1014. As can be seen in Figure 3, the handle 1014 may comprise a pair of interconnectable segments of the handle cabinet 1016 and 1018 which may be interconnected by screws, snap-fit members, adhesive, etc. In the illustrated arrangement, the grip cabinet segments 1016, 1018 cooperate to form a pistol grip portion 1019. Figures 1 to 3 depict a motor-driven cutting and clamping surgical instrument 1010 that may or may not be reused. In the illustrated embodiment, instrument 1010 includes a front housing 1012 comprising a handle 1014 that is configured to be gripped, manipulated, and actuated by the physician. Cabinet 1012 is configured for operational attachment to an interchangeable drive shaft assembly 1200 that has a surgical end actuator 1300 operatively coupled to it that is configured to perform one or more surgical tasks or procedures. As the present Detailed Description continues, it will be understood that the various forms of interchangeable drive shaft assemblies disclosed herein can also be used effectively in connection with robotically controlled surgical systems. Thus, the term "compartment" may also encompass a compartment or similar portion of a robotic system that houses or otherwise operationally supports at least one drive system configured to generate and apply at least one motion of a robot. control that can be used to drive the interchangeable drive shaft assemblies disclosed in the present invention and their equivalents. In addition, multiple components can be "housed" or contained within the case, or multiple components can be "associated with" a case. In such cases, the components may not be contained within the case or supported directly by the case. The term "structure" may refer to a portion of a hand-held surgical instrument. The term "structure" may also represent a portion of a robotically controlled surgical instrument and/or a portion of the robotic system that can be used to operationally control the surgical instrument. For example, the interchangeable drive shaft assemblies disclosed herein can be used with various robotic systems, instruments, components, and methods disclosed in US Patent No. 9,072,535 entitled SURGICAL STAPLING INSTRUMENTS WITH ROTATABLE STAPLE DEPLOYMENT ARRANGEMENTS, the which is incorporated herein by reference in its entirety.

[0224] Front cabinet 1012 shown in Figure 1 is shown in relation to an interchangeable drive shaft assembly 1200 (Figures 2, 4, and 5) that includes an end actuator 1300 that comprises a surgical cutting and clamping device. which is configured to operationally hold a 4000 surgical staple cartridge in it. The 1012 cabinet can be configured for use in

connection with interchangeable drive shaft assemblies that include end actuators that are adapted to support different sizes and types of staple cartridges, have different sizes and types of drive shafts, etc. In addition, the 1012 cabinet can also be used effectively with a variety of other drive shaft assemblies including assemblies that are configured to apply other motion and forms of energy such as radio frequency (RF) energy. , ultrasonic energy and/or motion to end actuator arrangements adapted for use in connection with various surgical applications and procedures. In addition, end actuators, drive shaft assemblies, handles, surgical instruments, and/or surgical instrument systems may use any suitable fastener, which can be grasped by the clinician. As will be discussed in more detail below, the handle 1014 operatively supports within it a plurality of drive systems which are configured to generate and apply various control movements to corresponding portions of the interchangeable drive shaft assembly. that is operationally attached to it.

[0225] Now referring to Figure 3, the handle 1014 may also include a frame 1020 that operatively supports a plurality of drive systems. For example, frame 1020 may operationally support a "first" drive system or closing drive system, commonly designated as 1030, which can be used to apply closing and opening motions to the shaft assembly. interchangeable drive 1200 that is operatively attached or coupled to it. In at least one form, the closure drive system 1030 may include an actuator in the form of a closure trigger 1032, which is pivotally supported by frame 1020. More specifically, as illustrated in Figure 3, the closure trigger - ment 1032 is pivotally coupled to housing 1014 by a pin 1033. This arrangement allows the closing trigger 1032 to be manipulated by a clinician so that when the clinician grasps the pistol grip portion 1019 of the grip 1014, the closing trigger 1032 can be easily pivoted from a home or "non-actuated" position to an "actuated" position and, more particularly, to a fully compressed or fully actuated position. Closing trigger 1032 may be biased to the non-actuated position by means of a spring or other biasing arrangement (not shown). In various forms, the lock drive system 1030 additionally includes a lock link assembly 1034, which is pivotally coupled to the lock trigger 1032. As can be seen in Figure 3, the lock link assembly 1034 may include a first locking link 1036 and a second locking link 1038 which are pivotally coupled to the locking trigger 1032 by a pin

1035. The second locking link 1038 may also be referred to herein as a "clamping member" and include a transverse clamping pin.

1037.

[0226] Still referring to Figure 3, it can be seen that the first locking link 1036 may have therein a locking wall or end 1039, configured to cooperate with a locking release assembly 1060 that is pivotally coupled to frame 1020. In at least one form, lock release assembly 1060 may comprise a release button assembly 1062 that has a distally projecting locking tongue 1064 formed thereon. The 1062 release button assembly can be pivoted counterclockwise by a release spring (not shown). When the clinician presses the lock trigger 1032 from its non-actuated position towards the pistol grip portion 1019 of the grip 1014, the first locking link 1036 pivots upward to a point where the locking pawl 1064 drops into a retaining engagement with the locking wall 1039 on the first closing link 1036, thus preventing the closing trigger 1032 from returning to the non-actuated position. Thereby, the lock release assembly 1060 serves to lock the lock trigger 1032 in the fully actuated position. When the clinician wishes to unlock the lock trigger 1032 to allow it to be biased to the non-actuated position, the clinician simply pivots the release button assembly 1062 so that the locking pawl 1064 is moved out of the way. engagement with locking wall 1039 at first locking link 1036. When locking pawl 1064 is moved out of engagement with first locking link 1036, locking trigger 1032 may pivot back to the non-actuated position. . Other arrangements for locking and releasing the closing trigger can also be used.

[0227] An arm 1061 can extend from the release button assembly 1062. A magnetic element 1063, such as a permanent magnet, for example, can be mounted to the arm 1061. When the release button assembly 1062 is rotated from its first position to its second position, magnetic element 1063 may move toward circuit board 1100. Circuit board 1100 may include at least one sensor that is configured to detect movement of magnetic element 1063. In at least one embodiment , for example, a "Hall effect" sensor (not shown) can be mounted on the bottom surface of the 1100 circuit board. The Hall effect sensor can be configured to detect changes in a magnetic field surrounding the sensor. Hall effect caused by the movement of magnetic element 1063. The Hall effect sensor may be in signal communication with a microcontroller, for example, which can determine whether the release button assembly 1062 is in the s a first position, which is associated with the non-actuated position of the closing trigger 1032 and the open configuration of the end actuator, its second position, which is associated with the actuated position of the closing trigger 1032 and the closed configuration of the actuator end, and/or any position between the first position and the second position.

[0228] In at least one form, the handle 1014 and frame 1020 may operatively support another drive system, called, in the present invention, a trigger drive system 1080, which is configured to apply trigger motions to the triggers. corresponding portions of the interchangeable drive shaft assembly fixed thereto. The trigger drive system 1080 may also be referred to in the present invention as the "second drive system". The trigger drive system 1080 may use an electric motor 1082 that is located in the pistol grip portion 1019 of the handle 1014. In various forms, the motor 1082 may be a brushed direct current drive motor with a maximum speed of approximately 25,000 rpm, for example. In other arrangements, the motor may include a brushless motor, a wireless motor, a synchronous motor, a stepper motor, or any other suitable electric motor. Motor 1082 may be powered by a power source 1090 which, in one form, may comprise a removable power source 1092. As can be seen in Figure 3, for example, the power pack 1092 may comprise a proximal cabinet portion. 1094 which is configured for attachment to a distal housing portion 1096. The proximal housing portion 1094 and the distal housing portion 1096 are configured to operatively support a plurality of batteries 1098 therein. Each of the batteries 1098 may comprise, for example, a lithium-ion ("LI") battery or other suitable battery. The distal cabinet portion 1096 is configured for operable removable attachment to the 1100 circuit board which is also operationally coupled to the 1082 motor. Multiple 1098 batteries, which can be connected in series, can be used as the power source for the instrument. 1010. Additionally, the power source 1090 may be replaceable and/or rechargeable.

[0229] As described above with respect to various other forms, the electric motor 1082 may include a rotating drive shaft (not shown), which operationally interfaces with a gear reducer assembly 1084, which is mounted in engagement coupling with a set, or rack, of drive teeth 1122 on a longitudinally movable drive member 1120. In use, a voltage polarity supplied by power source 1090 can operate electric motor 1082 clockwise, whereby the polarity of voltage applied to the electric motor by the battery can be reversed in order to run the electric motor 1082 counterclockwise. When the electric motor 1082 is rotated in one direction, the drive member 1120 will be axially driven in the distal direction "DD". When motor 82 is driven in an opposite rotary direction, drive member 1120 will be axially driven in the proximal "DP" direction. Handle 1014 may include a switch that may be configured to reverse the polarity applied to electric motor 1082 by power source 1090. As with the other forms described in the present invention, handle 1014 may also include a sensor that is configured to detect the position of drive member 1120 and/or the direction in which drive member 1120 is being moved.

[0230] The actuation of the 1082 motor can be controlled by a trigger 1130 which is pivotally supported on the handle 1014. The trigger trigger 1130 can be pivoted between a non-actuated position and an actuated position . Trigger trigger 1130 may be biased to the non-actuated position by means of a spring 1132 or other biasing arrangement so that when the physician releases trigger trigger 1130 it can be pivoted or otherwise returned. to the non-actuated position by spring 1132 or bias arrangement. In at least one way, trigger trigger 1130 may be positioned "outside" of closing trigger 1032, as discussed above. In at least one form, a trigger safety button 1134 may be pivotally mounted to the closing trigger 1032 by pin 1035. The safety button 1134 may be positioned between the trigger trigger 1130 and the triggering trigger. closure 1032 and having a pivot arm 1136 projecting therefrom. See Figure 3. When the close trigger 1032 is in the non-actuated position, the safety button 1134 is contained in the handle 1014, where the clinician cannot readily access it and move it between a safety position, which prevents actuation of trigger 1130, and a trigger position at which trigger trigger 1130 can be triggered. When the clinician presses the closing trigger 1032, the safety button 1134 and firing trigger 1130 pivot down to a position where they can then be manipulated by the clinician.

[0231] As indicated above, in at least one form, the longitudinally movable drive member 1120 has a tooth rack 1122 formed therein for meshing engagement with a corresponding drive gear 1086 of the gear reducer assembly 1084 At least one form also includes a manually actuatable "rescue" assembly 1140 which is configured to enable the clinician to manually retract the longitudinally movable drive member 1120 should the motor 1082 fail. Rescue assembly 1140 may include a lever or rescue handle assembly 1142 that is configured to be manually pivoted for ratchet engagement with teeth 1124 also provided on drive member 1120. In this way, the clinician can manually retract drive member 1120 using rescue handle assembly 1142 to engage drive member 1120 in the proximal "DP" direction. US Patent No. 8,608,045 entitled POWERED SURGICAL CUTTING AND STAPLING APPARATUS WITH MANUALLY RETRACTABLE FIRING SYSTEM discloses rescue arrangements and other components, arrangements and systems that can also be used with the various instruments disclosed herein.

TABLE SURGICAL INSTRUMENT COMPRISING AN ARTICULATION LOCK, now US Patent Application Publication No. 2014/0263541, is incorporated by reference into this report. As can be seen in Figure 4, the interchangeable drive shaft assembly 1200 may further include a proximal housing or nozzle 1201 composed of nozzle portions 1202 and 1203.

[0233] The interchangeable drive shaft assembly 1200 may additionally include a closing tube 3000 which may be used to close and/or open the anvil 2000 of the end actuator 1300. The drive shaft assembly 1200 may include a center column 1210 which is configured to, first, slidably support a trigger member therein, and second, slidably support closure member assembly 3000 that extends around central column 1210. As can be seen in Figure 5, a distal end 1212 of the center column 1210 terminates in an upper pin mounting feature 1270 and a lower pin mounting feature 1280. The upper pin mounting feature 1270 is formed with a pin slot 1272 therein which is adapted to mountably support an upper mounting link 1274 therein. Similarly, the lower pin crimp feature 1280 is formed with a pin slot 1282 therein that is adapted to mountably support a lower mounting link 1284 therein.

In at least one example, the closure member assembly 3000 comprises a proximal closure member segment 3010 that has a proximal end 3012 that is coupled to the closure shuttle 1250 for rotation thereto. For example, a U-shaped connector 1263 is inserted into an annular slot 3014 at the proximal end 3012 of the proximal closure member segment 3010 and is retained within the vertical slots 1253 in the closure shuttle 1250. This arrangement serves to secure the Proximal Closing Member Segment 3010 to the Closing Shuttle 1250 for axial displacement therewith, while allowing the Closing Member Segment 3010 to rotate relative to the Closing Shuttle 1250 around the axis geometry of the SA drive axis ("shaft axis"). A Closing Spring 1268 is seated over the Proximal Closing Member Segment 3010 and serves to bias the Proximal Closing Member Segment 3010 in the proximal "DP" direction, which can serve to pivot the Closing Trigger 1032 to the non-actuated position when drive shaft assembly is operationally coupled to handle 1014.

[0237] In at least one form, the interchangeable drive shaft assembly 1200 may also include a pivot joint 3020. Other interchangeable drive shaft assemblies, however, may not be capable of pivoting. As can be seen in Figure 5, for example, a distal closure member or distal closure tube segment 3030 or is coupled to the distal end of the proximal closure member segment 3010. Pivot joint 3020 includes a locking sleeve assembly. 3022 Double Pivot Closure. According to various shapes, the 3022 Double Pivot Closure Sleeve Assembly includes a 3050 End Actuator Closure Tube which has the upper and lower distally projecting connection terminals 3052, 3054. One upper dual pivot link 3056 includes upwardly projecting distal and proximal pivot pins that respectively engage an upper distal hole in the proximally projecting upper connecting terminal 3052 and an upper proximal hole in an upper connecting terminal distally projecting 3032 into the distal closure tube segment 3030. A lower dual pivot link 3058 includes distal and proximal pivot pins that project am upwards that respectively engage a lower distal hole in the proximally projecting lower connection terminal 3054 and a lower proximal hole in the distally projecting lower connection terminal 3034. See Figures 4 and 5. As per Figures 4 and 5. will be discussed in more detail below, the closing member assembly 3000 is translated distally (DD direction) to close the anvil 2000, for example, in response to actuation of the closing trigger 1032. The anvil 2000 is opened by means of the proximal translation of the closure member assembly 3000 which causes the end actuator closure tube 3050 to interact with the anvil 2000 and pivot it to an open position.

[0238] As also indicated above, the interchangeable drive shaft assembly 1200 additionally includes a trigger member 1900 which is supported to effect an axial displacement within the torso 1210. The trigger member 1900 includes an intervening portion. Firing drive shaft 1222 which is configured to connect to a distal cutting portion or cutter bar 1910. The intermediate firing drive shaft portion 1222 may include a longitudinal slot 1223 at its distal end which can be configured to receive a tab 1912 at the proximal end of the distal knife bar 1910. The longitudinal slot 1223 and proximal end tab 1912 can be sized and configured to allow movement.

relative movement therebetween and may comprise a sliding joint 1914. The sliding joint 1914 may allow a portion of the intermediate firing drive shaft 1222 of the firing member 1900 to be moved to pivot the end actuator 1300 without moving. , or at least without substantially moving, the knife bar 1910. Once the end actuator 1300 has been properly oriented, the intermediate-firing drive shaft portion 1222 can be advanced distally to a proximal side wall of the slot. 1223 makes contact with tab 1912 in order to advance cutterbar 1910 and fire staple cartridge 4000 positioned within elongated channel 1310. cutterbar 1910 includes a knife portion 1920 that includes a fabric cutting blade or edge 1922 and includes an upper anvil engagement flap 1924 and lower channel engagement flaps 1926. Various firing member configurations and operations are available. common in various other references incorporated herein by reference.

[0239] As can be seen in Figure 4, the drive shaft assembly 1200 additionally includes a switching cylinder 1500 which is rotatably received in the segment of the proximal closing member 3010. The switching cylinder 1500 comprises a segment hollow drive shaft 1502 having a drive shaft protrusion formed therein intended to receive an outwardly projecting actuating pin therein. In various circumstances, the actuation pin extends through a longitudinal slot provided in the locking sleeve to facilitate axial movement of the locking sleeve when it is engaged with the toggle driver. A rotating torsion spring 1420 is configured to engage the boss on the shift cylinder 1500 and a nozzle housing portion 1203 to apply a shifting force to the shift cylinder.

1500. Switch cylinder 1500 may further comprise at least partially circumferential openings 1506 defined therein, which may be configured to receive circumferential bezels that extend from nozzle portions 1202, 1203 and allow relative rotation. , but not translation, between the switching cylinder 1500 and the mouthpiece 1201. The bezels also extend through openings 3011 in the proximal closing member segment 3010 to be seated in recesses 1219 in the center column

1210. Rotation of switch cylinder 1500 about drive shaft geometry SA will ultimately result in rotation of the actuating pin and locking sleeve between their engaged and disengaged positions. In one arrangement, the rotation of the switching cylinder 1500 may be linked to the axial advance of the closing tube or closing member. In this way, essentially, the actuation of the closing system can operationally engage and disengage the linkage drive system with the trigger drive system in the various ways described in more detail in U.S. Patent Application Serial No. 13/803,086 now, US patent application publication No. 2014/0263541, entitled ARTICULATABLE SURGICAL INSTRUMENT COMPRISING AN ARTICULATION LOCK and US Patent No. 9,913,642, entitled SURGICAL INSTRUMENT COMPRISING A SENSOR SYSTEM, the disclosures of which are incorporated herein by reference in their totality. For example, when the closing member segment 3010 is in its most proximal position which corresponds to an "open jaws" position, the closing member segment 3010 will have positioned the switching drum 1500 so as to switch on. the linkage system to the triggering system. When the closing tube has been moved to its distal position corresponding to a "jaws closed" position, the closing tube rotates the switching drum 1500 to a position where the linkage system is disconnected from the drive system. - shooting ment.

[0240] Also as illustrated in Figure 4, the drive shaft assembly 1200 may comprise a slip ring assembly 1600 which may be configured to conduct electrical power to and/or the end actuator 1300 and/or therefrom. or communicate signals to and/or from the 1300 end actuator, for example. Slip ring assembly 1600 may comprise a proximal connector flange 1604 that mounts to a chassis flange 1242 that extends from chassis 1240 and a distal connector flange that is positioned within a slot defined in the cabinets. drive shaft. The proximal connector flange 1604 may comprise a first face and the distal connector flange may comprise a second face which is positioned adjacent and movable with respect to the first face. The distal connector flange can rotate with respect to the proximal connector flange 1604 around the axis of drive shaft SA. The proximal connector flange 1604 may comprise a plurality of concentric, or at least substantially concentric, conductors defined on its first face. A connector may be mounted on the proximal side of the connector flange and may have a plurality of contacts, each contact corresponding to and in electrical contact with one of the conductors. Such an arrangement allows relative rotation between the proximal connector flange 1604 and the distal connector flange, while maintaining electrical contact between them. Proximal connector flange 1604 may include an electrical connector 1606 that may place the leads in signal communication with a drive shaft circuit board 1610 mounted on drive shaft chassis 1240, for example. In at least one instance, an electrical harness comprising a plurality of conductors may extend between electrical connector 1606 and drive shaft circuit board 1610. Electrical connector 1606 may extend proximally through a 1243 connector opening defined in the 1242 chassis flange. See Figure 4. More details regarding the 1600 slip ring assembly can be found in patent application 13/803,086 entitled ARTICULATABLE SURGICAL INSTRUMENT COMPRISING AN ARTICULATION LOCK, now , patent application publication 2014/0263541, US patent application serial no. 13/800,067, titled STAPLE CARTRIDGE TISSUE THICKNESS SENSOR SYSTEM, filed March 13, 2013, now, US patent application publication no. 2014/0263552, and US Patent No. 9,345,481 entitled STAPLE CARTRIDGE TISSUE THICKNESS SENSOR SYSTEM, for example. US Patent Application Serial No. 13/803,086, now US Patent Application Publication No. 2014/0263541, US Patent Application Serial No. 13/800,067, now US Patent Application Publication No. 2014/0263552 and US Patent No. 9,345,481, which are each incorporated herein by reference in their entirety.

[0241] As discussed above, the drive shaft assembly 1200 may include a proximal portion that is fixably mounted to the handle 1014, and a distal portion that is rotatable about a longitudinal axis. The distal rotating portion of the drive shaft may be rotated with respect to the proximal portion around slip ring assembly 1600, as discussed above. The distal connector flange of the slip ring assembly 1600 may be positioned on the distal swivel portion of the drive shaft. Additionally, in addition to the above, the switching cylinder 1500 can also be positioned within the distal rotating portion of the drive shaft. When the distal rotating portion of the drive shaft is rotated, the distal connector flange and switching cylinder 1500 can be rotated synchronously with each other. In addition, the switching cylinder 1500 can be rotated between a first position and a second position with respect to the distal connecting flange.

When the switch cylinder 1500 is in its first position, the articulation drive system may be operationally disengaged from the trigger drive system, and therefore, the operation of the trigger drive system may not pivot the actuator. end cap 1300 of drive shaft assembly 1200. When shift cylinder 1500 is in its second position, the linkage drive system can be operationally engaged with the trigger drive system and thereby , the firing drive system operation can pivot the end actuator 1300 of the drive shaft assembly 1200. When the shift cylinder 1500 is moved between its first position and its second position, the shift cylinder 1500 is moved in relation to the distal connector flange. In various cases, drive shaft assembly 1200 may comprise at least one sensor configured to sense the position of switch cylinder 1500.

[0242] Again with reference to Figure 4, the chassis 1240 includes at least one, and preferably two, tapered attachment portions 1244 formed therein, which are adapted to be received within corresponding mating slots 1702 formed therein. within a distal attachment flange portion 1700 of frame 1020. See Figure 3. Each mating slot 1702 may be tapered or, in other words, approximately V-shaped to seat the attachment portions. 1244. As can also be seen in Figure 4, a drive shaft attachment pin 1226 is formed at the proximal end of the mid-firing drive shaft portion 1222. As will be discussed in more detail below, when the Interchangeable Drive Shaft Assembly 1200 is coupled to Handle 1014, Drive Shaft Attachment Pin 1226 is received in a Fire Drive Shaft Attachment Base 1126 formed in one end. and distal 1125 of longitudinal drive member 1120. See Figure 3.

[0243] Various embodiments of drive shaft assemblies use a locking system 1710 to detachably couple the drive shaft assembly 1200 to the cabinet 1012 and more specifically to the frame 1020. As can be seen in Figure 4 For example, in at least one form, lock system 1710 includes a lock member or lock fork 1712 that is movably coupled to chassis 1240. In the illustrated embodiment, for example, lock fork 1712 has a U-shape with two spaced, downwardly extending legs 1714. Each leg 1714 has a pivot pin 1715 formed therein that is adapted to be received in corresponding holes 1245 formed in the chassis 1240. Such an arrangement facilitates pivotal attachment. from the locking yoke 1712 to the chassis 1240. The locking yoke 1712 may include two proximally projecting locking pins 1716 that are configured to releasably engage the detents or corresponding locking grooves 1704 in the distal attachment flange 1700 portion of the frame 1020. See Figure 3. In various forms, the locking yoke 1712 is biased in the proximal direction by the spring or biasing member (not shown). Actuation of the locking yoke 1712 may be provided by a locking knob 1722 which is slidably mounted to a locking actuator assembly 1720 which is mounted on the chassis 1240. The locking knob 1722 may be tilted in either direction. proximal to the locking yoke 1712. As will be discussed in more detail below, the locking yoke 1712 can be moved to an unlocked position by biasing the locking knob in the distal direction, which also causes the locking yoke 1712 to pivot. out of retaining engagement with the distal attachment flange portion 1700 of the frame 1020. When the locking yoke 1712 is in retaining engagement with the distal attachment flange portion 1700 of the frame 1020, the locking pins 1716 are seated with retention within the corresponding detents or locking grooves 1704 in the distal attachment flange portion 1700.

[0244] When using an interchangeable drive shaft assembly that includes an end actuator of the type described here that is adapted to cut and grip tissue, as well as other types of end actuators, it may be desirable to prevent the inadvertent detachment of the interchangeable drive shaft assembly from the housing during actuation of the end actuator. For example, in use, the clinician can actuate the closing trigger 1032 to grasp and manipulate the target tissue into a desired position. When the target tissue is positioned within the end actuator 1300 in a desired orientation, the clinician can then fully actuate the closing trigger 1032 to close the anvil 2000 and secure the target tissue in position for cutting and stapling. In this case, the first drive system 1030 was fully actuated. After the target tissue has been secured to the end actuator 1300, it may be desirable to prevent inadvertent detachment of the drive shaft assembly 1200 from the cabinet 1012. One form of the locking system 1710 is configured to prevent this inadvertent detachment.

[0245] As can be more particularly seen in Figure 4, the locking yoke 1712 includes at least one and preferably two locking hooks 1718 which are adapted to contact the locking pin portions. corresponding 1256 which are formed in the closing shuttle 1250. When the closing shuttle 1250 is in a non-activated position (i.e. the first drive system 1030 is deactivated and the anvil 2000 is open), the closing yoke 1256 is in a non-activated position. Lock 1712 can be pivoted in a distal direction to unlock interchangeable drive shaft assembly 1200 from cabinet 1012. When in this position, lock hooks 1718 do not contact portions of lock pin 1256 on lock shuttle 1250. However, when the closing shuttle 1250 is moved to an actuated position (i.e., the first drive system 1030 is actuated and the anvil 2000 is in the closed position), the locking yoke 1712 is prevented from being pivoted to an unlocked position. In other words, if the clinician attempts to pivot the Locking Fork 1712 to an unlocked position or, for example, the Locking Fork 1712 has been inadvertently pushed or brought into contact in a way that could otherwise cause it pivots distally, the locking hooks 1718 on the locking yoke 1712 would contact the locking pin portions 1256 on the closing shuttle 1250 and preventing movement of the locking yoke 1712 to an unlocked position.

[0246] The attachment of the interchangeable drive shaft assembly 1200 to the handle 1014 will now be described. To begin the coupling process, the clinician may position chassis 1240 of interchangeable drive shaft assembly 1200 above or adjacent to distal attachment flange portion 1700 of frame 1020 so that the tapered attachment portions 1244 form into the chassis. 1240 align with slots 1702 in frame 1020. The clinician can then move drive shaft assembly 1200 along an installation axis that is perpendicular to drive axis geometry SA to seat the attachment portions 1244 in "operational engagement" with the corresponding dovetail receiving slots 1702. In doing so, the drive shaft attachment pin 1226 on the intermediate firing drive shaft portion 1222 will also be seated in the base 1126 on longitudinally movable drive member 1120 and pin portions 1037 on second locking link 1038 will be seated on corresponding hooks 1252 the closing shuttle 1250. As used in the present invention, the term "operable engagement" in reference to two components means that the two components are engaged with each other in such a way that upon application of an actuating motion to the same the components can perform the intended action, function and/or procedure.

[0247] At least five interchangeable drive shaft assembly 1200 systems may be operationally coupled to at least five corresponding 1014 grip systems. A first system may comprise a frame system that couples and/or aligns the frame or center column of drive shaft assembly 1200 with frame 1020 of handle 1014. Another system may comprise a closing drive system 1030 which can operatively connect the closing trigger 1032 of the handle 1014 and the closing tube 1260 and anvil 2000 of the drive shaft assembly 1200. As outlined above, the closing shuttle 1250 of the drive shaft assembly 1200 can be engaged with pin 1037 on the second lock link 1038. Another system may comprise the trigger drive system 1080 which can operatively connect the trigger trigger 1130 of the handle 1014 with the interlocking trigger shaft portion 1014. - midshaft 1222 of drive shaft assembly 1200. As outlined above, drive shaft attachment pin 1226 operatively connects to the base 1126 of the longitudinal drive member 1120. Another system may comprise an electrical system that can signal to a controller on the handle 1014, such as the microcontroller, for example, that a drive shaft assembly, such as the shaft assembly drive shaft 1200, for example, has been operationally engaged with handle 1014 and/or, two, conduct power and/or communication signals between drive shaft assembly 1200 and handle 1014. For example, drive shaft assembly 1200 - 1200 design may include an 1810 electrical connector that is operatively mounted to the 1610 drive shaft circuit board. The 1810 electrical connector is configured for mated engagement with a corresponding 1800 electrical connector on the grip control circuit.

1100. Additional details on the circuitry and control systems can be found in US Patent Application Serial No. 13/803,086, now, US Patent Application Publication No. 2014/0263541, and in US Patent Application Serial No. 14/226,142, now US Patent No. 9,913,642, the disclosures of which were previously incorporated by reference. The fifth system may consist of the locking system for releasably locking the drive shaft assembly 1200 to the handle 1014.

[0248] The anvil 2000 in the illustrated example includes an anvil body 2002 that terminates at the anvil mounting portion 2010. The anvil mounting portion 2010 is movably or pivotally supported in the elongated channel 1310 for selective pivotal displacement in relative thereto around a fixed anvil pivot axis PA that is transverse to the drive shaft SA axis. In the illustrated arrangement, an anvil pivot or pivot pin member 2012 extends laterally on either side of the anvil mounting portion 2010 to be received in a corresponding pivot pin base 1316 formed in the vertical walls 1315 of the end portion. proximal 1312 of the elongated channel

1310. The swivel pins of the anvil 2012 are pivotally retained in their corresponding swivel pin base 1316 by the channel cover or anvil retainer 1290. The channel cover or anvil retainer 1290 includes a pair of retaining pins that are configured to be retentively received within corresponding slots or pin notches formed in the vertical walls 1315 of the proximal end portion 1312 of the elongated channel 1310. See Figure 5.

[0249] Still referring to Figure 5, in at least one arrangement, the Distal Closing Member or Closing Tube of the 3050 End Actuator uses two positive jaw opening features, proximal and distal, axially offset 3060 and 3062. Positive jaw opening features 3060, 3062 are configured to interact with the corresponding raised areas and staggered portions formed in the anvil mounting portion 2010 as described in more detail in the US patent application Serial No. 15/635,631, entitled SURGICAL INSTRUMENT WITH AXIALLY MOVABLE CLOSURE MEMBER, now US Patent Application Publication No. 2019/0000464, the disclosure of which has been incorporated herein by reference, in its entirety. Other jaw opening arrangements can be used.

[0250] Figures 6 to 8 represent a surgical instrument for anterior cutting and fixation 5010 that is configured to generate rotary drive motions to operate a surgical end actuator 5012. The endoscopic surgical instrument 5010 comprises a handle 5006, a shaft 5008 drive shaft and a 5012 articulation surgical end actuator pivotally connected to the 5008 drive shaft on a 5014 articulation pivot. A 5016 articulation control may be provided adjacent to the 5006 handle to effect actuator rotation. 5012 around articulation pivot 5014. It will be understood that various embodiments may include a non-pivoting end actuator, and therefore may not have a articulation pivot 5014 or articulation control 5016.

[0251] The 5006 handle of the 5010 instrument may include a

5018 closing clip and a 5020 triggering trigger to actuate the 5012 end actuator. It will be understood that instruments that have end actuators targeted at different surgical tasks may have different numbers or types of triggers or other controls suitable for operate the 5012 end actuator. In one embodiment, a clinician or operator of the 5010 instrument can pivot the 5012 end actuator relative to the 5008 drive shaft using the 5016 pivot control, as described in more detail in the patent. US Pending No. 7,670,334 entitled SURGICAL INSTRUMENT HAVING AN ARTICULATING END EFFECTOR, the disclosure of which is incorporated herein by reference in its entirety. The end actuator 5012 in this example includes, among other things, a channel of clamps 5022 and a pivotally translatable clamping member, such as an anvil 5024, which are held in a spacing that ensures effective stapling and separation of tissue trapped in the end actuator 5012. The handle 5006 includes a pistol grip 5026 towards which the closing trigger 5018 is pivotally pulled by the clinician to cause the anvil 5024 to tighten or close in towards the clamp channel 5022 of the end actuator 5012 to thereby secure the tissue positioned between the anvil 5024 and the channel 5022.

[0252] In the arrangement shown in Figure 7, the end actuator 5012 includes, in addition to the previously mentioned channel 5022 and anvil 5024, a cutting instrument 5032, a slider 5033, a staple cartridge 5034 that is seated removable in channel 5022, and a helical screw drive shaft

5036. The cutting instrument 5032 can be, for example, a knife. Anvil 5024 includes pivot pins 5025 that are movably supported in corresponding slots in channel 5022. In one arrangement, anvil 5024 includes a tab 5027 at its adjacent end that is inserted into a component of a mechanical closure system ( described further below) to open and close anvil 5024.

[0253] Still referring to Figure 7, the drive shaft 5008 includes a proximal closure tube 5040 and a distal closure tube 5042 pivotally connected by a pivot link 5044. The distal closure tube 5042 includes an opening 5045 into which tab 5027 on anvil 5024 is inserted to open and close anvil 5024, as further described below. Disposed within the closure tubes 5040, 5042 may be an adjacent back tube 5046. Disposed within the adjacent back tube 5046 may be a main (or adjacent) rotary drive shaft 5048 that communicates with a secondary drive shaft. (or distal) 5050 through a 5052a bevel gear set c. The secondary drive shaft 5050 is connected to a drive gear 5054 which engages an adjacent drive gear 5056 of the helical screw drive shaft 5036. The vertical bevel gear 5052b can seat and pivot in an opening 5057 in the distal end of the adjacent backbone tube 5046. A distal backtube 5058 may be used to surround the secondary drive shaft 5050 and the drive gears 5054, 5056. Collectively, the main drive shaft 5048, the secondary drive shaft 5050 and the linkage assembly (eg, bevel gear assembly 5052a ac) is sometimes referred to in the present invention as "main drive shaft assembly".

[0254] A bearing 5038, positioned at a distal end of the clamp channel 5022, receives the 5036 helical screw drive shaft, allowing the 5036 helical screw drive shaft to rotate freely with respect to the 5022 channel. screw drive shaft 5036 can interface with a threaded opening (not shown) of knife 5032 so that rotation of the screw drive shaft 5036 causes knife 5032 to translate distally or proximally (depending on the - rotation reaction) through clamp channel 5022.

[0255] Returning to Figure 8, the grip 5006 includes outer lower side pieces 5059, 5060 and mouthpiece pieces 5061, 5062 that fit together to form the overall exterior of the grip 5006. A battery 5064, such as a battery pack Li ion, can be supplied in the 5026 pistol grip of the 5006 grip. The 5064 battery powers a 5065 motor disposed in an upper portion of the 5026 pistol grip portion of the 5006 grip. The 5065 motor can drive a bevel gear assembly 90° 5066 which comprises a first bevel gear 5068 and a second bevel gear 5070. The bevel gear assembly 5066 can drive a set of planetary gears 5072. The planetary gear set 5072 can include a pinion gear 5074 connected to a 5076 drive shaft. The 5074 pinion gear can drive a 5078 mating annular gear that drives a 5080 helical gear drum via a steel shaft. tion. A 5084 ring can be threaded onto the worm gear drum

5080. Thus, when the motor 5065 rotates, the ring 5084 is forced to move along the 5080 helical gear drum via the interposed bevel gear set 5066, the planetary gear set 5072, and the annular gear 5078.

[0256] Handle 5006 may include an intermediate part of handle 5104 adjacent to the upper portion of the trigger

5020. Handle 5006 may also comprise a bias spring 5112 connected between columns at the midpiece of the handle 5104 and the trigger trigger 5020. The bias spring 5112 may bias the trigger trigger 5020 to its fully open position . That way, when the operator releases the 5020 trigger, the 5112 bias spring will pull the 5020 trigger to its open position. The distal end of the 5080 worm gear drum includes a 5120 distal drive shaft that drives an annular gear 5122, which mates with a 5124 pinion gear. The 5124 pinion gear is connected to the 5048 main drive shaft. of the main drive shaft assembly. In this way, rotation of the 5065 motor causes the main drive shaft assembly to rotate, which causes the 5012 end actuator to act. The 5084 ring threaded into the 5080 helical gear drum can include a 5086 column that is disposed within a slot 5088 of a slotted arm 5090. The slotted arm 5090 has an opening 5092 at its opposite end 5094 which receives a pivot pin 5096 which is connected between the outer side pieces of the handle 5059, 5060. The pivot pin 5096 is also disposed through an opening 5100 in the trigger 5020 and an opening 5102 in the midpiece of the handle 5104.

[0257] Handle midpiece 5104 includes a rear shoulder 5106 that engages the slotted arm 5090. Handle midpiece 5104 also has a forward motion lock 5107 that engages firing trigger 5020. of the slotted slot 5090 is controlled by the rotation of the motor 5065. When the slotted arm 5090 rotates counterclockwise as the ring 5084 moves from the adjacent end of the worm gear drum 5080 to the distal end, the intermediate piece handle 5104 will be free to turn counterclockwise. That way, as the user pulls the trigger trigger 5020, the trigger trigger 5020 will engage the forward motion lock 5107 of the middle grip piece 5104, making

causing the middle grip piece 5104 to rotate counterclockwise. Due to the rear shield 5106 which engages the slotted arm 5090, however, the intermediate grip piece 5104 will only be able to rotate counterclockwise as far as the slotted arm 5090 will allow. That way, if the motor 5065 stops rotating for some reason, the slotted arm 5090 will stop rotating, and the user will not be able to additionally pull the trigger trigger 5020 because the middle part of the handle 5104 will not be free to rotate counterclockwise due to the slotted arm 5090.

[0258] The components of an exemplary closing system for closing (or securing) the anvil 5024 of the end actuator 5012 by retracting the closing trigger 5018 are also shown in Figure 8. In the illustrated embodiment, the closing system includes a fork 5250 connected to Closing Trigger 5018. A Pivot Pin 5252 is inserted through slots aligned in both Closing Trigger 5018 and Fork 5250 so that they both pivot about the same point. The distal end of the 5250 yoke is connected, via a 5254 pin, to a 5256 first closing bracket. The 5256 first closing bracket connects to a 5258 second closing bracket. Collectively, the 5256 closing brackets , 5258 defines an opening in which the adjacent end of the proximal closure tube 5040 (see Figure 7) is seated and held so that longitudinal movement of the closure brackets 5256, 5258 causes longitudinal movement by the proximal closure tube

5040. The instrument 5010 also includes a closure drive shaft 5260 disposed within the proximal closure tube 5040. The closure drive shaft 5260 may include a window 5261 in which a column 5263 in one of the outer parts of the handle, like the lower outer side piece 5059 in the illustrated embodiment, is arranged to fixedly connect the lock drive shaft 5260 to the handle 5006. In this way, the proximal lock tube 5040 is able to move longitudinally with respect to the drive axis. - closure feature 5260. Closure drive shaft 5260 may also include a distal collar 5267 which fits into a cavity in adjacent dorsal tube 5046 and is retained therein by a cap.

[0259] In operation, when the yoke 5250 rotates due to retraction of the closing trigger 5018, the closing trigger 5256, 5258 causes the proximal closing tube 5040 to move distally (i.e., away from the end of the instrument handle 5010), which causes the Distal Closure Tube 5042 to move distally, which causes the Anvil 5024 to rotate around the Pivot Pins 5025 to the locked or closed position. When the Closing Trigger 5018 is unlocked from the locked position, the Proximal Closure Tube 5040 causes proximal sliding, which causes the Distal Closure Tube 5042 to slide proximally, which because the tab 5027 is inserted in the opening 5045 of the distal closure tube 5042, causes the anvil 5024 to pivot about the pivot pins 5025 to the open or unsecured position. In this way, by retracting and locking the closing trigger 5018, an operator can clamp the tissue between the anvil 5024 and the channel 5022, and can release the tissue after the cutting/stapling operation by unlocking the closing trigger 5018 from the locked position. . Further details regarding the construction and operation of the existing 5010 surgical instrument can be found in US Patent No. 7,845,537 entitled SURGICAL INSTRUMENT HAVING RECORDING CAPABILITIES, the disclosure of which is incorporated herein by reference in its entirety. Other rotary drive arrangements configured for use with various forms of robotic systems are disclosed in patent application publication 2016/0287251 entitled STAPLING END EFFEC-

TOR CONFIGURED TO COMPENSATE FOR AN UNEVEN GAP BETWEEN A FIRST JAW AND A SECOND JAW, the disclosure of which is hereby incorporated in its entirety by way of reference.

[0260] Figures 9 to 16 represent a 20012 surgical end actuator that can be used, for example, in connection with the 5010 powered surgical instrument described above. The 20012 Surgical End Actuator can also be effectively used with various other powered or robotically powered rotary surgical systems that are disclosed in the various references incorporated herein by reference. The components shown in Figures 9 through 16 that are identical to the components of the 5010 powered surgical instrument have been identified with similar component numbers. In the illustrated example, the 20012 surgical end actuator comprises an elongated channel 20020 that is configured to operatively support a 20040 surgical staple cartridge therein. The 20020 elongated channel is similar to the 5022 channel described above, except for the differences noted. Returning to Figure 10, the elongated channel 20020 comprises a pair of spaced vertical walls 20022 and a bottom 20024. The helical screw drive shaft 5036 is supported in the channel 20020 by a bearing 5038 which allows the helical screw 5036 rotates freely with respect to channel 20020. The surgical end actuator 20012 additionally comprises an anvil 5024 which has pivot pins or swivel pins 5025 which are received in corresponding slots 20026 provided in the vertical walls of channel 20022.

[0261] In the illustrated arrangement, the staple cartridge 20040 includes an elongate cartridge body 20042 that is sized to be removably seated in the elongate channel 20020. The cartridge body 20042 includes a cartridge slot 20050 that extends from a portion from proximal end 20046 to a distal end portion 20044 of cartridge body 20042. Cartridge body 20042 further comprises a cartridge platform surface 20043 that faces a lower staple-forming surface 5029 of anvil 5024 when cartridge 20040 is seated in channel 20020 and anvil 5024 is pivoted to a closed position. Also in the illustrated example, three rows of 20052 surgical staple pockets are formed on either side of the 20050 cartridge slot and open across the platform surface of the 20043 cartridge. Each 20052 staple pocket can have a staple driver (no - auger) associated with it that supports a surgical clip or fastener (not shown) on it.

[0262] Still referring to Figure 10, the staple cartridge 20040 additionally includes a cam assembly 20060 comprising a cam assembly body 20062 having a passage 20064 therethrough that is configured to sit on the shaft 5036 helical screw drive without affecting its rotation. In other embodiments, cam assembly 20060 may have a series of internal threads (not shown) that are configured to threadably engage helical screw drive shaft 5036 to be so driven. In such arrangements, for example, the helical screw drive shaft 5036 may be provided with an unthreaded portion corresponding to an initial position of the cam assembly 20060. Such arrangements of a cam assembly are further described in various references which have been incorporated herein by reference. In the illustrated example, cam assembly 20060 is driven distally through cartridge body 20042 by firing member 20120.

[0263] As can be further seen in Figure 10, the cam assembly body 20062 includes a series of cam members 20066 that are aligned with corresponding staple drivers supported in rows within the staple cartridge body 20042. In the illustrated example, the cam assembly 20060 includes an inner tissue cutting member or blade 20068. The tissue cutting member 20068 extends above the platform surface 20043 so that when the cam assembly 20060 is actuated distally, wherein the 20068 tissue cutting member cuts the tissue that is trapped between the 5024 anvil and the 20040 staple cartridge. When the staple cartridge is "fresh" or new (i.e. the cartridge has never been fired and contains the staples or fasteners therein ready to be fired), cam assembly 20060 is homed within cartridge 20040. When cam assembly 20060 is homed, tissue cutting member 20068 is in place. located within a garage portion 20048 formed in the proximal end portion 20046 of the cartridge body 20042 to prevent injury during handling of the new cartridge 20040. In one aspect, the cam members 20066 extend distally beyond the cutting member. 20068 so that the staples or fasteners are implanted through the tissue before the 20068 tissue cutting member cuts the tissue.

In this way, the trapped tissue is stapled and then cut as the triggering member 20120 and a cam assembly 20060 are driven distally.

After the trigger member 20120 and cam assembly 20060 have been driven to their most distal end positions, the trigger member 20120 can be retracted to its home position by rotating the auger auger 5036 in a direction reverse rotating while the 20060 cam assembly remains in its final position.

In at least one arrangement, the tissue cutting member 20068 is movable from an activated cutting position to a storage position in which the tissue cutting member 20068 is stored below the 20043 cartridge platform surface to prevent injury. while handling the fired or spent cartridge 20040. For example, a retraction member (not shown) can be strategically located at the distal end 20044 of the cartridge body 20042 to contact and move the tissue cutting member 20068 from the activated position to the storage position when a portion of the fabric cutting member 20068 is brought into contact with the retraction member.

[0264] Figure 11 represents a shape of a trigger member

20120. As can be seen in Figure 11, the trigger member 20120 comprises a body portion 20122 that includes two downwardly extending hollow mounting portions 20124 that are unthreaded and spaced apart to receive a drive nut. threaded 20130 between them. Threaded drive nut 20130 is configured to threadably engage helical screw drive shaft 5036. Drive nut 20130 includes a vertical tab portion 20131 that is sized to extend through an axial slot 20025 (Figure 10) on the bottom 20024 of the elongate channel 20020. Two laterally extending retaining flanges 20134 are formed on the threaded drive nut 20130 and are configured to engage the bottom 20024 of the elongate channel 20020. In addition, two anvil engaging tabs which laterally extending 20126 are formed on top of the trigger member body 20122 and are configured to engage corresponding bosses 20102 formed on the anvil 5024 as the trigger member 20120 is moved axially within the surgical end actuator 20012.

[0265] As can also be seen in Figure 11, the trigger member 20120 may also be equipped with an internal trigger member locking assembly 20140 which comprises a locking member 20142 which is pivotally coupled to the internal triggering member 20140. trigger member body 20122. Lock member 20142 includes a slider lock 20148 lock that is configured to be engaged by cam assembly 20060 when cam assembly 20060 is in a non-triggered position. As can be seen in Figures 12 and 13, the cam assembly 20060 includes a trigger member boss 20061 configured to engage the slider lock 20148 on the locking member.

20142. Locking spring 20150 is mounted in elongated channel 20020 and is configured to bias locking member 20142 downwards so that if cam assembly 20060 is not in its unfired home position, locking member 20142 goes into contact with locking pins 20028 which are formed in portions of the inner surface of each vertical side wall 20022 of the elongated channel

20020. See Figure 15. When in this position, if the user inadvertently attempts to advance the 20120 triggering member distally, the 20142 locking member contacts the 20028 locking pins in the 20020 channel to prevent distal advancement of the limb. trigger 20120.

[0266] Figure 12 illustrates the initial insertion of a new unfired surgical staple cartridge 20040 into channel 20020. As can be seen in Figure 12, the cam assembly 20060 is in a home position and the proximal end portion 20046 of the surgical staple cartridge 20040 is inserted at an angle to the channel 20020 and then pushed in the proximal direction DP until the protrusion of the triggering member 20061 on the cam assembly 20060 unlockably engages the slider lock portion 20148 of the 20142 locking member. Figures 13 and 14 illustrate the 20040 Surgical Staple Cartridge in a correctly installed position. As can be seen in Figure 13, the firing member locking assembly

20140 is in an unlocked position. Rotating actuation of the helical screw drive shaft 5036 in a first rotational direction will cause the triggering member 20120 to move distally in the distal direction DD. As the trigger member 20120 moves distally, the cam assembly 20060 is thereby also actuated distally. The 20066 cam members provide cam movement to the drivers stored in the 20040 cartridge upwards in the 20042 cartridge body. As the drivers cam upward, the surgical clamps or fasteners supported thereon are driven through the tissue that has been clamped. between the anvil 5024 and the cartridge 20040 and making contact with the lower staple forming surface 5029 on the anvil 5024. The stapled tissue is then cut by the tissue cutting member 20068. When the firing member 20120 has been triggered for its In the most distal position on the 20040 cartridge, the 5036 helical screw drive shaft can be rotated in a second, opposite direction of rotation to retract the 20120 firing member back to its home position. Cam assembly 20060 remains in distal end portion 20044 of cartridge body 20042. Spent cartridge 20040 can then be removed from channel 20020.

[0267] Figure 14 illustrates the 20012 end actuator after the spent cartridge has been removed from the 20020 channel. As can be seen in Figure 14, the spring 20150 biases the locking member 20142 of the triggering member locking assembly 20140 into engagement with the 20028 locking pins in the 20020 channel. If the user attempts to trigger the 20012 Surgical End Actuator (distally advancing the 20120 triggering member), the 20142 locking member will prevent the 20120 triggering member from move distally. Likewise, if the user tries to reuse the spent cartridge because the cam assembly 20060 is not in the home position, the triggering member 20140 locking assembly will prevent the distal advancement of the triggering member 20120.

[0268] In the illustrated arrangement, the locking member 20142 is pivotally coupled to the triggering member body 20122 by pivot pins 20143 which are received in a hole 20123 which extends through the triggering member body 20122. See Figures 14 and

16. In at least one arrangement, pivot pins 20143 are sized relative to holes 20123 in firing member body 20122 to facilitate free pivoting displacement of locking member 20142 and to account for differences in component tolerance. As can be seen in Figure 14, the triggering member 20120 includes a proximally facing triggering surface 20145 that is configured to be contiguous with a distally facing bearing surface 20125 on the body of the triggering member 20122 when the assembly 20140 firing member locking lever is in the unlocked position. In this way, when the triggering member 20120 is advanced distally, the resistive forces encountered by the cam assembly 20060 during its distal movement are directly applied to the distal-facing bearing surface 20125 on the triggering member body.

20122. Such an arrangement can prevent the transfer of these resistive forces back to the 20143 pivot pins, which can cause the 20143 pivot pins to fail under such a load. Similarly, as can be seen in Figure 16, the proximally facing angled bearing surface 20145 of the triggering member 20120 is configured to be contiguous with the distally facing bearing surface 20125 on the body of the triggering member 20120 20122 when the 20140 firing member locking assembly is in the locked position. Such an arrangement can prevent the transfer of resistive locking forces resulting from the locking engagement of the 20142 locking member with the 20028 locking pins back to the 20143 pivot pins, which can cause the 20143 pivot pins to fail. under such a load. Loose fit between pins 20143 and hole 20123 in triggering member body 20122 facilitates some translation of locking member 20142 when under load to facilitate transfer of loads into triggering member body 20122 and not onto the pins 20143 itself.

[0269] In another arrangement, or in addition to the previously described locking member arrangement 20142, the amount of current being drawn by the motor used to apply the rotary motions to the helical screw drive shaft 5036 is monitored. Once the current increases beyond a predetermined threshold, a control circuit for the surgical instrument or robotic system, etc., can stop the motor to prevent any further rotation of the 5036 helical screw drive shaft and movement. of the 20120 tripping member to prevent damage to the components described above.

[0270] Some previous trigger member locking arrangements that are configured to prevent advancement of a trigger member from the end actuator unless a new unfired staple cartridge has been properly installed in the surgical end actuator, require that the user actively retracts the firing member back to its most proximal starting position before allowing the anvil to open. If the user tries to open the anvil before the triggering member is moved back to its most proximal position, the user may not understand why the anvil cannot open. The arrangement described above can avoid such confusion.

[0271] Figures 17 to 21 depict a surgical end actuator 20300 that can be used, for example, in connection with the powered surgical instrument 1010 described above. The 20300 Surgical End Actuator can also be effectively used with

There are several other robotically powered surgical systems which are disclosed in the various references incorporated herein by reference. The components shown in Figures 17 to 21 that are identical to the components of the 1010 surgical instrument have been identified with similar component numbers. The construction and function of the 1010 surgical instrument components that are not necessary to understand the operation of the 20300 Surgical End Actuator will not be repeated here for the sake of brevity.

[0272] Referring to Figures 17 through 21, the surgical end actuator 20300 includes an elongated channel 20310 that is configured to operatively support a surgical staple cartridge 20600 therein. In the illustrated example, the elongated channel 20310 comprises end a channel bottom 20312 and a pair of vertical sidewalls

20314. Channel 20310 is coupled to elongated drive shaft assembly 1200 (Figure 5) by a channel mounting feature 20340 that can facilitate its pivoting around pivot joint 3020 (Figure 5). As can be seen in Figure 19, in one arrangement for example, the channel mounting feature 20340 comprises a body portion 20342 consisting of a vertical support 20344 which has a slot 20346 extending therethrough to receive the firing member beam 1900 (Figure 5) therethrough. The channel mount feature 20340 can be movably or pivotally mounted to a proximal end 20316 of the channel 20310 by a channel mount feature, or channel pin 20320. In particular, the channel mount feature 20320 further includes a transverse pin opening 20348 which is configured to be coaxially aligned with holes 20318 in side walls 20314 of channel 20310 to receive channel pin 20320 therethrough.

[0273] As described above, the drive shaft assembly

1200 includes a 1210 center column that terminates in a 1270 upper stud mounting feature and a 1280 lower stud mounting feature. See Figure 5. The 1270 upper stud mounting feature is formed with a slot. pin 1272 thereon which is adapted to mountably support an upper mounting link 1274 thereon. Similarly, the lower pin crimp feature 1280 is formed with a pin slot 1282 therein that is adapted to mountably support a lower mounting link 1284 therein. The upper mounting link 1274 includes a pivot socket 1276 therein is adapted to pivotally receive therein a pivot pin 1292 which is formed in a channel cap or anvil retainer 1290 which is secured to the proximal end portion 20316 of the channel elongated 20310. As can be seen in Figure 19, the channel mounting feature 20340 additionally includes a drive shaft mounting flange 20350 that extends proximally therefrom. In one arrangement, for example, the drive shaft mounting flange 20350 has a centrally disposed pivot hole 20352 therethrough which can pivotally receive the lower pivot pins 1286 on the lower mounting link 1284 of the drive feature. bottom 1280 pin assembly (Figure 5). Lower pivot pin 1286 is vertically aligned with pivot socket 1276 to define a pivot axis AA about which surgical end actuator 20300 can pivot with respect to center column 1210. In one arrangement, pivot driver 20300 can pivot with respect to center column 1210. 2102 (Figure 5) can be directly coupled to a pivot pin 20354 formed in the 20350 drive shaft mounting flange. In other arrangements, the proximal pivot driver 2102 can be attached to one or more pivot links. tion that are fixed to the drive shaft mounting flange

20350. In either case, axial movement of the proximal hinge driver 2102 in the manner described above will cause the channel mount feature to pivot about the hinge axis with respect to the central column 1210 (Figure 5) to hinge the 20300 end actuator around the AA joint geometry axis.

[0274] The 20300 Surgical End Actuator additionally comprises a 20400 anvil that is very similar to the 2000 anvil described above, except for the differences discussed below. The anvil 20400 includes an elongated anvil body portion 20402 that has a lower clamp-forming surface 20404 and an anvil mounting portion 20410 that is configured to interact with the end actuator closing tube 3050 (Figure 5) of the anvil. manner described above. The anvil 20400 is pivotally mounted to the elongated channel 20310 by a pair of laterally extending pivot pins or anvil pins 20412 that are received in corresponding elongated pivot pin slots 20322 formed in the vertical walls of the channel 20314. O Axial movement of the 3050 End Actuator Closing Tube in a distal direction will cause the 20400 Anvil to pivot to a closed position about a pivot axis defined by the 20412 Anvil Swivel Pins and the Motion of the Actuator Closing Tube end cap 3050 in a proximal direction will cause the anvil to pivot to an open position with respect to the elongated channel

20310

[0275] Figure 22 illustrates one form of a staple cartridge 20600 that can be used in conjunction with the surgical end actuator 20300. In at least one arrangement, the surgical staple cartridge 20600 comprises an elongate cartridge body 20602 that is sized to be removably seated in elongate channel 20310. Cartridge body 20602 includes a cartridge slot 20608 that extends from a proximal end portion 20604 to a distal end portion 20606 (Figure 17) of the cartridge body 20602. Cartridge body 20602 further comprises a cartridge platform surface 20610 which faces the lower staple forming surface 20404 of anvil 20400 when cartridge 20600 is seated in channel 20310 and anvil 20400 is pivoted to a closed position. . Also in the illustrated example, three rows of surgical staple pockets 20612 are formed on each side of cartridge slot 20608 and open through the surface of cartridge deck 20610. Each staple pocket 20612 can have a staple driver ( not shown) associated therewith, which supports a surgical clip or fastener (not shown) thereon. In at least one example, the cartridge body 20602 is molded from a polymeric material with the staple pockets 20612 molded or machined therein. In one arrangement, the 20612 staple pockets also open through a bottom of the 20602 cartridge body to facilitate installation of the drivers and fasteners into their respective 20612 pockets. After the drivers and fasteners are inserted into their respective pockets 20612 staples, a 20620 cartridge tray is attached to the bottom of the cartridge body

20602. In one form, the cartridge tray 20620 is manufactured from a metallic material and includes a bottom 20622 that extends through the bottom of the cartridge body 20602 and two vertical side walls 20624 that correspond to each side of the cartridge body 20602. Cartridge tray 20620 may be removably attached to cartridge body 20602 by a series of hooks 20626 which are formed in side walls 20624 and configured to hookably engage corresponding portions of cartridge body 20602. See Figure 22. When installed, the 20620 cartridge tray can, among other things, prevent the drivers and fasteners from falling out of the bottom of the 20602 cartridge body when handling and installing the 20600 cartridge in the 20310 elongated channel.

[0276] As discussed above in connection with the 20040 cartridge, the 20600 cartridge operatively supports a cam assembly within it. The cam assembly comprises a series of spaced-apart cam members that are configured to move axially within corresponding cam slots 20609 formed on either side of cartridge slot 20608 in cartridge body 20602. Cam slots 20609 are aligned with the corresponding rows of drivers on the 20602 cartridge body to facilitate cam contact with a corresponding cam member as the cam assembly is driven through the 20600 staple cartridge from a home position within the cam portion. proximal end 20604 of cartridge body 20602 to an end position within distal end portion 20606.

[0277] The example illustrated in Figures 20 and 21 also uses a 20500 trigger member that is attached to a distal end of the 1900 trigger member beam and beam is configured to interface operatively with the cam assembly on the staple cartridge 20600 to drive the cam assembly from its home position to its final position within the 20600 cartridge. In at least one arrangement, the firing member 20500 is configured to interact with a cam assembly (not shown) in a staple cartridge 20600 that has been properly installed in the elongate channel 20310. For example, the firing member 20500 includes a firing member body 20502 that has a fabric cutting surface or blade 20504 formed therein or affixed thereto. at the same. The firing member body 20502 is sized to move axially within an axial anvil slot (not shown) in the anvil 20400 as well as the cartridge slot 20608 in the cartridge body 20602 and a channel slot (not shown) in the channel 20310. A lower foot assembly 20506 comprising a pair of laterally extending lower flanges 20508 extends from one end.

lower edge of the firing member body 20502 until it slidably engages the corresponding channel protrusions (not shown) that are formed on each side of the channel slot. An upper foot (not shown) comprising two laterally extending anvil lugs may be formed at an upper end of the firing member body 20502 and is configured to slidably engage the anvil protrusions (not shown). ) that are formed on either side of the anvil slit. In at least one arrangement, the firing member 20500 additionally includes a pair of central flaps 20510 that extend laterally on either side of the firing member body.

20502

[0278] Still referring to Figures 20 and 21, in one arrangement, the triggering member body 20502 is configured with a proximally extending spring tail 20512 that can be configured to operatively interface with a locking spring 20520 of trigger member which is mounted on elongate channel 20310 and is configured to bias trigger member 20500 downwardly (arrow PB) on elongate channel 20310 to a locked position. When in the locked position, the foot of the trigger member 20506 and/or the central tabs 20510 are misaligned with corresponding passages in the channel 20310 and as such, should the user attempt to advance the trigger member 20500 distally when in that locked state, the trigger member 20500 will not move distally due to such misalignments. That is, the foot 20506 and/or the central tabs 20510 contact portions of the elongated channel to thereby prevent distal advancement of the firing member.

20500. In one arrangement, a slider lock 20514 is formed on the trigger member body 20502 and is configured to be engaged by a corresponding portion formed on a cam assembly that is operatively supported on the surgical staple cartridge 20600.

When a new unfired staple cartridge 20600 with its cam assembly in its home position is operatively installed in the elongated channel 20310, a portion of the cam assembly engages the slider lock 20514 on the firing member body 20502 and moves the firing member 20500 up (up arrow in Figure 20) to an unlocked position in which the lower foot assembly 20506 and/or the center tab assembly 20510 are aligned with the respective passages in the channel 20310 to allow allow the 20500 trigger member to advance axially within it. As the user distally advances the 20500 triggering member on the 20600 cartridge, the 20500 triggering member also drives the cam assembly on the 20500 cartridge that provides cam movement to the drivers upwards to drive the clamps or clips. res supported on it in forming contact with the underside of the anvil. The fabric cutting member 20504 in the triggering member 20500 then cuts through the stapled fabric. After the trigger member 20500 has been driven to its most distal position which corresponds to the end position of the cam assembly, the trigger member 20500 is retracted back to its most proximal position, leaving the cam assembly at the distal end 20606 of the cartridge 20600. When the triggering member 20500 returns to its most proximal starting position, the locking spring of the triggering member 20520 again biases the triggering member 20500 back to its locked position. That way, if the user inadvertently tries to reuse the spent cartridge 20600, the cam assembly is not in its home position which is needed to unlock the firing member 20500.

[0279] The 20300 Surgical End Actuator may also use a 20700 Closing Locking System to prevent the 20400 Anvil from being moved from an open position to a closed (clamped) position unless a matching 20600 Surgical Staple Cartridge is compatible. operationally installed in the elongated channel 20310. In the illustrated example, the 20700 closing lock system comprises an anvil lock 20702 that is configured to move between a locked anvil position and an unlocked anvil position in response installing a 20600 staple cartridge in it. Figure 19 illustrates one form of an anvil latch 20702. The anvil latch member 20702 can be fabricated from spring steel or other suitable metal and include a proximal biasing arm 20704 that can be configured to seat in a Cross spring mounting slot 20343 provided in body portion 20342 of channel mounting feature 20340. Anvil latch 20702 further includes a distally extending body portion 20706 that has a downwardly extending mounting tab 20708 and an upwardly extending anvil locking tab 20710 protruding therefrom. As can be seen in Figures 17, 18, and 20 the mounting tab 20708 is for a clearance window 20319 which is formed in the elongated channel

20310

[0280] Figure 19 illustrates the 20300 Surgical End Actuator without a Surgical Staple Cartridge installed in it. As can be seen in Figure 19, the proximal biasing arm 20704 has biased the anvil latch 20702 in the distal "anvil latched" position. When in this position, the anvil locking tab 20710 is aligned with a portion of an anvil locking pin 20414 that is formed in the anvil mounting portion 20410 of the anvil 20400. Should the user attempt to close the anvil 20400, the anvil locking pin 20414 will contact the anvil locking tab 20710 to thereby prevent any further displacement of the anvil 20400 in the closing direction.

[0281] Returning to Figure 21, in at least one arrangement, the staple cartridge 20600 includes an anvil unlocking feature or tab 20630 that projects proximally from the cartridge body 20602 and is aligned to unlockably engage a tab. 20712 which is formed at the distal end of the anvil latch 20702 when the 20600 cartridge is operatively installed in the 20310 elongated channel. Figure 20 depicts the 20600 surgical staple cartridge operatively installed in the elongated channel.

20310. As can be seen in Figure 21, the anvil release tab 20630 on the staple cartridge body 20602 contacted the actuation tab 20712 of the anvil lock 20702 and biased the anvil lock 20702 in the proximal direction DP to an unlocked position, whereby the anvil locking tab 20710 is no longer aligned with the anvil locking pin 20414 on the anvil 20400. When in this position, the user can pivot the anvil 20400 to a closed position. If the user attempts to install an inappropriate cartridge that does not have the 20630 Anvil Unlock Tab or similar feature designed to unlock the 20702 Anvil Lock, the user will not be able to close the 20400 Anvil to complete the procedure. stapling surgery.

[0282] Figure 23 illustrates an alternate closure locking system 20700' to prevent an anvil 20400' of a surgical end actuator 20300' from being moved from an open position to a closed (clamped) position unless a cartridge of matching 20600 surgical clips have been operatively installed in the corresponding elongated channel (not shown). The 20300' Surgical End Actuator is substantially identical to the 20300 Surgical End Actuator described above, except for the differences noted below. The closing latch system 20700' comprises an anvil latch 20702' which is substantially identical to the anvil latch 20702 described above, except for the following differences. For example, anvil latch 20702 may be manufactured from spring steel or other suitable metal and include a distally extending body portion 20706' which has a spring portion 20707' formed therein. A proximal end of the anvil lock 20702' has an anchor tab 20703' formed thereon that serves to couple the anvil lock 20702' to the channel mount feature 20340 (Figure 19). Additionally, the body portion 20706' includes a downwardly extending mounting tab 20708' and an upwardly extending anvil locking tab 20710' projecting therefrom. An actuation tab 20712' is formed at the distal end of the body portion 20706'.

[0283] The Surgical Staple Cartridge 20600' is similar to the Surgical Staple Cartridge 20600 described above and includes a cartridge body 20602' which is sized to be removably seated in the elongated channel 20310. The cartridge body 20602' includes a cartridge slot 20608' extending from a proximal end portion 20604' to a distal end portion of cartridge body 20602. Cartridge body 20602' further comprises a cartridge platform surface 20610' and three rows of surgical staple pockets 20612' located on either side of cartridge slot 20608'. As can be seen in Figure 23, the staple pockets 20612', as well as the staples or fasteners therein (not shown) are aligned on the geometric axes of the pockets PA' which are parallel to the cartridge slot 20608'. In this way, the staples/fasteners are applied in lines that are approximately parallel to the 20608' cartridge slot and the fabric cut line. Like the Surgical Staple Cartridge 20600, the Surgical Staple Cartridge 20600' includes a cartridge tray 20624' and an anvil unlocking feature or tab 20630' protruding proximally from the cartridge body 20602'.

[0284] Still referring to Figure 23, the anvil 20400' is similar to the anvil 20400, except for the differences discussed below.

The anvil 20400' includes an elongated anvil body portion 20402' and an anvil mounting portion 20410' that is configured to interact with the end actuator closing tube 3050 (Figure 5) in the manner described above. .

The anvil body portion 20402' includes a lower staple forming surface 20404' that is cut by an anvil slot 20405' that is configured to accommodate the passage of the firing member 20500 therethrough.

As can be seen in Figure 23, the lower staple forming surface 20404' comprises three rows of staple forming pockets 20407' which are arranged on the forming pocket axes ("FPA"). ) that are parallel to the anvil slit 20405'. When the anvil 20400' is moved to a closed position, the anvil slot 20405' is vertically aligned with the cartridge slot 20608' to allow the firing member 20500 to pass therethrough.

The rows of 20407' staple forming pockets are aligned with the 20612' staple pockets so that as the staples are driven from the 20600' cartridge, they come into contact with a corresponding pair of staple forming pockets. 20407' to be crimped.

Thus, the array of staple forming pockets on the anvil 20400' needs to match the array of staple pockets 20612' on the cartridge 20600' to ensure that the staples are properly formed.

As can be further seen in Figure 23, in this arrangement, the anvil 20400' includes a downwardly extending anvil locking pin 20414' which is formed distal to the anvil mounting portion 20410', but is otherwise mode, configured to contact the anvil locking tab 20710' when the anvil locking tab 20702' is in the locked position (e.g. no cartridges were inserted in channel 20310 or an inappropriate cartridge was seated in channel 20310) . When the cartridge 20600' is properly seated in the elongated channel 20310, its anvil unlocking feature 20630' makes contact with the actuation tab 20712' on the anvil lock 20702' to bias the lock 20702' pro- proximally to the unlocked position where the anvil locking tab 20710' is out of locking alignment with the anvil locking pin 20414' to allow the anvil 20400' to be pivoted to the closed position.

[0285] Figure 24 illustrates an alternative 20700'' latching system to prevent an anvil 20400'' of another surgical end actuator 20300'' from being moved from an open position to a closed (stuck) position. unless a compatible 20600'' Surgical Staple Cartridge has been operatively installed in the 20310 elongated channel. The 20300'' Surgical End Actuator is substantially identical to the 20300 Surgical End Actuator described above, except for the differences noted below. The closing locking system 20700'' comprises an anvil locking 20702'' which is substantially identical to the anvil locking 20702 described above, except for the following differences. For example, anvil latch 20702'' may be manufactured from spring steel or other suitable metal and include a distally extending body portion 20706'' which has a spring portion 20707'' formed therein. A proximal end of the anvil lock 20702'' has an anchor tab 20703'' formed therein that serves to couple the anvil lock 20702'' to the channel mount feature 20340 (Figure 19). Additionally, body portion 20706'' includes a downwardly extending mounting tab 20708'' and an upwardly extending anvil locking tab 20710' projecting therefrom. An actuation tab 20712'' is formed at the distal end of the body portion 20706''.

[0286] The Surgical Staple Cartridge 20600'' is similar to the Surgical Staple Cartridge 20600 described above and includes a cartridge body 20602'' which is sized to be removably seated in the elongated channel 20310. The cartridge body 20602'' ' includes a cartridge slot 20608'' extending from a proximal end portion 20604'' to a distal end portion of cartridge body 20602''. Cartridge body 20602'' further comprises a cartridge platform surface 20610'' and two rows of surgical staple pockets 20612'' located on either side of cartridge slot 20608''. As can be seen in Figure 24, the staple pockets 20612'', as well as the staples or fasteners therein (not shown) are aligned on the geometric axes of the pockets PA'' which are transverse to the slot of the 20608'' cartridge. . In this way, the staples/fasteners are applied in lines that are approximately transverse to the 20608'' cartridge slot and the fabric cutting line. Such fastener arrangements create "flexible" or "stretchable" staple lines. Additional details regarding cartridges for developing flexible and stretchable staple lines can be found in US Patent Application Serial No. 14/498,121 entitled FASTENER CARTRIDGE FOR CREATING A FLEXIBLE STAPLE LINE, now US Patent No. 9,801,627, the disclosure of which is incorporated herein by reference in its entirety. Like the Surgical Staple Cartridge 20600, the Surgical Staple Cartridge 20600'' includes a cartridge tray 20624'' and an anvil unlocking feature or tab 20630'' that projects proximally from the cartridge body 20602'.

[0287] Still referring to Figure 24, the anvil 20400'' is similar to the anvil 20400, except for the differences discussed below. The anvil 20400'' includes an elongated anvil body portion 20402'' and an anvil mounting portion 20410'' that is configured to interact with the end actuator closing tube 3050 (Figure 5) in the manner described above.

The anvil body portion 20402'' includes a lower clamp forming surface 20404'' that is cut by an anvil slot 20405'' that is configured to accommodate the passage of the firing member 20500 therethrough.

As can be seen in Figure 24, the lower staple forming surface 20404'' comprises rows of staple forming pockets 20407'' which are arranged on the geometric axes of FPA forming pockets that are transverse to the slit. of anvil 20405''. When the anvil 20400'' is moved to a closed position, the anvil slot 20405'' is vertically aligned with the cartridge slot 20608'' to allow the firing member 20500 to pass therethrough.

The rows of 20407' staple forming pockets are aligned with the 20612' staple pockets so that as the staples are driven from the 20600' cartridge, they contact a corresponding pair of 20407 forming pockets. ' to be crimped.

Thus, the array of staple forming pockets 20407'' on the anvil 20400'' needs to match the array of staple pockets 20612'' on the cartridge 20600'' to ensure that the staples are properly formed.

As can be further seen in Figure 24, in this arrangement, the anvil 20400'' includes a downwardly extending anvil locking pin 20414'' which is formed or secured to the anvil mounting portion 20410'' and is configured to contact the 20710'' Anvil Lock Tab when the 20702'' Anvil Lock is in the locked position (e.g. no cartridge is inserted into channel 20310 or an inappropriate cartridge is inserted into channel 20310) . When the 20600'' cartridge is properly seated in the 20310 elongated channel, its 20630'' anvil unlocking feature contacts the 20712'' actuation tab on the 20702'' anvil lock to bias the 20702'' anvil lock. ' proximally to the unlocked position where the anvil locking tab 20710'' is out of locking alignment with the anvil locking pin 20414'' to allow the anvil 20400'' to be pivoted close.

[0288] As discussed above, various surgical staple cartridges may have different dies and/or staple/fastener orientations in them. The sizes of clips or fasteners as well as the number of fasteners may vary from cartridge type to cartridge type depending on a specific surgical procedure or application. To ensure that staples are properly crimped or formed, surgical staple cartridges need to be used in connection with mating anvils that have the proper array of staple forming pockets in it. If a "non-compatible" cartridge is loaded into an end actuator that has an anvil that is not misaligned with the cartridge, the clamps may not be properly formed during the firing process, which can lead to catastrophic results. . For example, the 20600' surgical staple cartridge shown in Figure 23 is aligned with or "compatible with" the 20400' anvil shown in Figure 23. The 20600'' surgical staple cartridge shown in Figure 24 corresponds to or compatible with the anvil 20400'' shown in Figure 24. However, the surgical staple cartridge 20600'' of Figure 24 is incompatible with the anvil 20400' shown in Figure 23, for example.

[0289] Closing interlock systems used in the examples described above can prevent activation of a misaligned cartridge that has otherwise been loaded into the end actuator. For example, the anvil release feature or tab 20630' on the staple cartridge 20600' is situated on the left side of the cartridge slot 20608' and is positioned to contact the actuator tab 20712' on anvil locking spring 20707' when cartridge 20600' is properly loaded in channel 20310 of end actuator 20300'. On the other hand, the 20630'' anvil unlocking feature or tab on the 20600'' cartridge is situated on the right side of the 20608'' cartridge slot and aligned to contact the 20712'' actuator tab on the anvil lock. 20702'' when cartridge 20600'' is properly loaded into channel 20310. If user loads cartridge 20600'' into channel 20310 of end actuator 20300'', the anvil unlocking feature or tab 20630'' on the cartridge 20600'' clamp cho will not contact actuator tab 20712' on anvil lock 20702' to move it to the unlocked position and user will be unable to pivot anvil 20400' closed.

Similarly, if the user loads the 20600' cartridge into the 20300'' end actuator channel, the 20630' anvil release feature or tab on the 20600' staple cartridge will not contact the 20712 actuator tab. '' on locking anvil 20702'' to move it to the unlocked position and the user will be unable to pivot anvil 20400'' closed.

If the user unintentionally loads another cartridge that does not have the proper anvil locking feature or tab that matches the anvil locking on the end actuator, the user will not be able to close the anvil.

The location, format, length, etc. of the anvil release features or tabs on a surgical staple cartridge may vary from cartridge type to cartridge type and be interrelated to the actuating member (size, location, shape, number, etc.) in the corresponding anvil lock located at a corresponding surgical end actuator.

For example, the anvil release feature or tab may be integrally formed into the cartridge body, be machined or molded into the cartridge body, be secured to the cartridge body, be secured to or integrally formed into the cartridge cam assembly, or comprising a portion of the cartridge tray, for example.

All such variations are contemplated by the present invention and are intended to be covered by the appended claims.

[0290] Figures 25 to 29 illustrate a 21300 Surgical End Actuator that is very similar to the 20300, 20300', 20300” Surgical End Actuators described above, except for the differences noted below. In this embodiment, for example, the end actuator 21300 comprises an elongate channel 21310 which is configured to operatively support a surgical staple cartridge 21600 therein. In the illustrated example, the elongate channel 21310 comprises a channel bottom 21312 and a pair of vertical side walls 21314. Although not shown, the channel 21310 may be coupled to the elongate drive shaft assembly 1200 (Figure 5) by a mounting feature. - channel tang 20340 (described above) that can facilitate its articulation around the articulation joint 3020 (Figure 5). The 21300 Surgical End Actuator additionally comprises a 21400 anvil that is very similar to the 20400 anvil described above, except for the differences discussed below. The anvil 21400 includes an elongated anvil body portion 21402 that has a lower clamp-forming surface and an anvil mounting portion 21410 that is configured to interact with an end actuator closing tube 3050 (Figure 5) in the manner described above. The anvil 21400 is pivotally mounted to the elongate channel 21310 by a pair of laterally extending pivot pins or anvil pins 21412 that are received in corresponding elongate pivot pin slots 21320 that are formed in the vertical walls of the channel 21314. Axial movement of the End Actuator Closing Tube 3050 in a distal direction will cause the Anvil 21400 to translate distally until the Swivel Pins 21412 contact the distal ends of their respective Swivel Pin Slots 21320 and pivot into a position closed. On the other hand, movement of the end actuator closing tube 3050 in a proximal direction will cause the anvil 21400 to pivot to an open position with respect to the elongated channel 21310.

[0291] The 21300 End Actuator is configured to operatively support a 21600 Surgical Staple Cartridge which may be substantially the same as the 20600 Surgical Staple Cartridge, except that the 21630 Anvil Unlocking Feature or Tab comprises a portion of the 21630 Surgical Staple Tray. cartridge 21620. Anvil unlocking feature 21630 is configured to operatively interact with an axially movable anvil latch 21702 that is supported by channel 21310. Returning to Figure 27, anvil latch 21702 is supported for axial movement between a position a distal locked position and a proximal locked position by a guide block 21720 that is attached to a portion of the channel 21310. In one example, the anvil lock 21702 may be formed from metal and the guide block 21720 may be manufactured from 6/6 nylon filled with 40% carbon and be attached to the 21314 side wall of the 21310 channel by an adhesive or other suitable fastening means. Guide block 21720 may define a guide channel 21722 which is configured to support a locking tab portion 21710 of the anvil latch.

21702. The anvil latch 21702 further comprises a vertical body portion 21706 which has an actuation tab 21712 formed at its distal end. The 21702 anvil latch is biased into a distal locked position by a 21730 extension spring that is secured to the 21702 anvil latch and the canal sidewall.

21314. When no cartridge is present, extension spring 21730 biases anvil latch 21702 to a distal latched position where locking tab portion 21710 contacts a portion of anvil 21400 to prevent anvil 21400 from pivoting to a closed position. When a suitable or compatible cartridge 21600 is loaded into the elongated channel 21310, the unlocking feature or tab 21630 of the cartridge tray 21620 contacts the actuation tab 21712 on the anvil latch 21702 to move the anvil latch 21702 proximally to a unlocked position where the locking tab portion 21710 of the anvil lock 21702 no longer prevents pivoting movement of the anvil

21400. As can be seen in Figure 25, the design of the 21630 anvil unlock feature of the 21600 Surgical Staple Cartridge is "asymmetric". That is, the anvil release feature 21630 is situated on only one side of a proximal end of the 21600 cartridge. Figure 25 illustrates an old relief area 21315 that is present in previous channel arrangements and new relief areas 21317 , 21319 which are provided in channel 21310 to accommodate cartridge 21600 therein.

[0292] Figure 30 illustrates portions of a 21300' Surgical End Actuator that is identical to the 21300 End Actuator, except that the 21300' End Actuator uses a 21702' Anvil Latch as depicted in Figures 31 and 32. In one example, anvil latch 21702' may be fabricated from 6/6 nylon filled with 40% carbon and includes a vertical body portion 21706' that has a locking portion 21710' formed at its upper end. . An actuation tab 21712' is formed at a distal end and a bellows 21714' is also used to provide additional support for the actuation tab 21712'. As discussed above, when a suitable or compatible surgical staple cartridge 21600 is loaded into the elongated channel 21310, the unlocking feature or tab 21630 of the cartridge tray 21620 makes contact with the actuation tab 21712' on the release latch. anvil 21702' to move anvil latch 21702' proximally to an unlocked position where the locking portion 21710' of anvil latch 21702' no longer impedes pivoting movement of anvil 21400.

[0293] Figure 33 illustrates another 22300 Surgical End Actuator that uses a 22700 Anvil Locking System. The 22300 End Actuator is similar to the 20300 End Actuator described above, except for the differences noted. In this embodiment, the end actuator 22300 comprises an elongated channel 22310 which is configured to operatively support a cartridge of surgical staples 22600 therein. In the illustrated example, the elongate channel 22310 comprises a channel bottom 22312 and a pair of vertical side walls 22314. Although not shown, the channel 22310 may be coupled to the elongate drive shaft assembly 1200 (Figure 5) by a feature. channel mount 20340 (described above) that can facilitate its pivoting around pivot joint 3020 (Figure 5). The Surgical End Actuator 22300 additionally comprises an anvil 22400 which is very similar to the anvil 20400 described above, except for the differences discussed below. The anvil 22400 includes an elongated anvil body portion 22402 and an anvil mounting portion 22410 that is configured to interact with an end actuator closing tube 3050 (Figure 5) in the manner described above. The anvil 22400 is pivotally mounted to the elongated channel 22310 by a pair of laterally extending pivot pins or anvil pins 22412 that are received in corresponding elongated pivot pin slots 22320 formed in the vertical side walls of the channel.

22314. Axial movement of the 3050 End Actuator Closing Tube in a distal direction will cause the 22412 Anvil Swivel Pins to translate distally to the 22320 Swivel Pin Slots to pivot the 22400 Anvil to a closed position. On the other hand, movement of the end actuator closure tube 3050 in a proximal direction will cause the anvil 22400 to pivot to an open position with respect to the elongated channel.

22310.

[0294] The 22300 End Actuator is configured to operationally support a 22600 Surgical Staple Cartridge which can be substantially the same as the 20600 Surgical Staple Cartridge, except that the 22630 Anvil Unlocking Feature or Tab is formed on a right side of a proximal end portion 22604 of cartridge body 22602 and has a contoured proximal end surface of cartridge 22632. In the illustrated example, contoured proximal end surface 22632 has an arcuate shape. The anvil unlocking feature 22630 is configured to operatively interact with an axially movable anvil latch 22702 of the 22700 anvil locking system that is supported by the 22310 channel. In the illustrated example, the anvil latch 22702 is supported for axial movement between a 22310 channel. distal locked position and a proximal unlocked position within a proximal end portion 22316 of the elongate channel 22310. In the illustrated example, the anvil lock 22702 comprises an elongate body portion 22706 that has an anvil locking tab 22710 formed into its proximal end is configured to interlock in a locked manner with a locking pin 22413 formed in the anvil mounting portion 22410 of the anvil 22400. See Figure 33. An actuation tab 22712 is formed at a distal end of the anvil 22400 portion. of body 22706. Actuation tab 22712 has a contoured actuation surface 22714 formed thereon which is configured to substantially match or mate with contoured proximal end surface 22632 on anvil unlocking feature 22630. See Figure 34.

[0295] In at least one arrangement, a spring or biasing member 22730 (spring bundle, coil spring, etc.) may be attached to or mounted within the 22310 channel and configured to bias the 22702 anvil latch in the direction distal DD to the locked position where the locking tab of the anvil 22710 thereon is in locking alignment with the locking pin 22413 on the anvil mounting portion 22410 to prevent the anvil 22400 from closing. of suitable or compatible surgical staples 22600 is operationally loaded into channel 22310, the anvil release feature or tab 22630 is placed in engagement with contoured surface 22714 on actuation tab 22712 of the anvil lock 22702. The 22600 Surgical Staple Cartridge is then moved proximally to seat the 22600 Cartridge within the 22310 channel. As the 22600 Surgical Staple Cartridge is moved proximally, the 22630 Anvil Unlocking feature comes into play. contact with the actuation tab 22712 of the 22702 anvil lock and biases the anvil lock 22702 proximally to the unlocked position where the anvil locking tab 22710 thereon is moved out of locking alignment with the pin lock 22413 on anvil mounting portion 22410 to allow anvil 22400 to pivot closed. When the surgical staple cartridge 22600 is removed from the channel 22310, the spring 22730 biases the anvil latch 22702 distally back to the locked position. Figure 35 illustrates that the contoured proximal end 22632 of the anvil unlocking feature 22630 formed on a right side of the proximal end portion 22604 of the cartridge body 22602 and the corresponding contoured surface 22714 on the actuation tab 22712 of the 22702 anvil locks allow the 22600 cartridge to facilitate the unlocking interaction between the 22630 unlocking feature and the 22712 actuation tab even when the cartridge is installed at an installation angle IA ("installation angle") to the axis 22300 End Actuator EA Center Geometric. See Figure 35.

[0296] Figure 36 illustrates the attempted use of an incompatible cartridge

22600X lacking an unlocking feature to move the 22702 anvil latch from the locked position to the unlocked position. As can be seen in Figure 36, locking tab 22710 is in locking alignment with locking pin 22413 on anvil 22400 to thereby prevent anvil 22400 from being closed even after cartridge 22600X has been seated in channel 22310 .

[0297] Figure 37 illustrates another 22300' Surgical End Actuator that is substantially identical to the 22300 Surgical End Actuator described above, except for the differences noted below. End actuator 22300' is configured to operatively support a staple cartridge 22600' that is substantially the same as the cartridge 20600 and includes an anvil unlocking feature or tab 22630' that has a contoured proximal end surface 22632'. In the illustrated example, the anvil latch 22702' comprises an elongated body portion 22706' that has an anvil latching tab 22710' formed at its proximal end 22711' and configured to latch interact with a locking pin 22413 ' formed in the anvil mounting portion 22410 of the anvil

22400. A distal end 22712' of the anvil latch 22702' includes a contoured actuation surface 22714' formed therein that is configured to substantially match or mate with the contoured proximal end surface 22632' on the anvil unlocking feature 22630' in the ways described above. A spring or biasing member 22730 (spring bundle, coiled spring, etc.) can be attached to or mounted within the 22310 channel and configured to bias the 22702 anvil latch in the distal direction DD to the latched position in which its anvil latch 22702 anvil lock 22710 is in lock alignment with lock pin 22413 on anvil mounting portion 22410 to prevent anvil from closing

22400

[0298] When a suitable or compatible surgical staple cartridge 22600' is operationally loaded into channel 22310', the anvil unlocking feature or tab 22630' is placed in engagement with the contoured surface 22714' of the anvil latch 22702'. Cartridge 22600' is then moved proximally in a proximal direction DP to seat cartridge 22600' within channel 22310'. As the 22600' cartridge is moved proximally, the 22630' anvil release feature contacts the distal end of the 22702' anvil latch and biases the 22702' anvil latch proximally to the unlocked position in which its anvil latch 22702' is moved proximally. Anvil lock 22710 is moved out of lock alignment with locking pin 22413 on anvil mounting portion 22410 to allow anvil 22400 to pivot closed. When cartridge 22600' is removed from channel 22310', spring 22730' biases anvil latch 22702' distally back to the locked position. As can be seen in Figure 37, when compared to the anvil latch 22702 described above, the anvil latch 22702' has a more robust body portion 22706'. In at least one example, a clearance notch 22709' is provided in the body portion 22706' to provide sufficient clearance for the lock pin 22413' when the anvil 22400 is pivoted to the closed position. In addition, a channel lock 22313' is formed in a bottom 22312' of channel 22310' and is configured to contact the proximal end 22711' of anvil lock 22702' when anvil lock 22702' is in position. unlocked position to prevent anvil latch 22702' from moving more proximally to ensure that locking pin 22413' remains aligned with clearance notch 22709' in anvil latch 22702' during closing of anvil 22400.

[0299] Figure 38 illustrates another 22300'' surgical end actuator that can be identical to the surgical end actuator

22300 described above, except for the differences noted below. End actuator 22300'' comprises an elongated channel 22310'' that includes an anvil 22400'' that is pivotally supported thereon. The 22310'' channel is configured to operationally support a 22600 surgical staple cartridge that is compatible with the bottom staple forming surface of the 22400'' anvil and uses a 22700'' anvil locking system that is configured to prevent - tar the 22400'' anvil closure unless a 22600 Surgical Staple Cartridge has been operationally installed in the 22300'' End Actuator. In the illustrated example, the anvil locking system 22700'' includes a locking anvil 22702'' that comprises a body portion 22706'' that has a distal end portion 22712'' that is larger than a proximal portion of the body. 22706''. When the anvil latch 22702'' is in its most distal locked position, a portion of the anvil 22400'' contacts the higher distal end portion 22712'' to prevent the anvil 22400'' from being closed. The distal end portion 22712'' of the anvil lock 22702'' includes a contoured actuation surface 22714'' that is configured to substantially match or mate with the contoured proximal end surface 22632'' on the 22630 anvil unlocking feature formed in the 22600 cartridge in the ways described above. A spring or biasing member 22730'' (spring bundle, coil spring, etc.) can be attached to or mounted within the 22310'' channel and be configured to bias the 22702'' anvil latch in the distal direction DD to the locked position in which the distal end portion 22712'' is in locking line with the locking pin with the corresponding portion of the anvil 22400'' to prevent the anvil 22400'' from closing.

[0300] When a suitable or compatible 22600 surgical staple cartridge is operationally loaded into channel 22310'', the anvil unlocking feature 22630 on cartridge 22600 is placed in engagement with contoured surface 22714'' at distal end 22712' ' of anvil latch 22702''. Cartridge 22600 is then moved proximally to seat cartridge 22600 within channel 22310''. As the 22600' cartridge is moved proximally, the 22630 anvil unlocking feature contacts the 22712" distal end of the 22702' anvil latch and biases the 22702' anvil latch proximally to the unlocked position in which the 22702' anvil latch distal end 22712'' is moved out of locking alignment with the corresponding portion of anvil 22400'' to allow anvil 22400'' to pivot to a closed position. When cartridge 22600 is removed from channel 22310'', spring 22730'' biases anvil latch 22702'' distally back to the locked position. As can also be seen in Figure 38, a channel lock 22313'' is formed in a bottom 22312'' of channel 22310'' and is configured to contact a proximal end 22711'' of the anvil lock 22702'' to prevent cartridge 22600 from being inserted too far proximally into end actuator 22300''.

[0301] Figures 39 and 40 illustrate another 23300 surgical end actuator that is similar to the other surgical end actuators described here with the exception of the various differences noted below. End actuator 23300 comprises an elongated channel 23310 that includes an anvil 23400 that is pivotally supported thereon. The 23310 channel is configured to operationally support a 22600 surgical staple cartridge that is compatible with the 23400 anvil staple forming surface and uses a 23700 anvil locking system that is configured to prevent closure.

anvil 23400 unless a cartridge 22600 has been operatively installed in the end actuator 23300. In the illustrated example, the anvil locking system 23700 comprises an anvil latch 23702 comprising a body portion 23706 that has a portion distal end portion 23712. The distal end portion 23712 of the anvil lock 23702 includes a contoured actuation surface 23714 that is configured to substantially match or mate with the contoured proximal end surface 22632 on the anvil unlocking feature. 22630 which is formed into the 22600 cartridge in the ways described above. A spring or biasing member 23730 is mounted within the channel 23310 and is configured to bias the anvil latch 23702 in the distal direction DD to a "locked" position.

[0302] In the illustrated example, the anvil 23400 includes an elongated anvil body 23402 and an anvil mounting portion 23410 that is configured to interact with an end actuator closing tube 3050 (Figure 5) in the manner described above. . The anvil 23400 is pivotally mounted to the elongate channel 22310 by a pair of laterally extending pivoting pin formations 23412 that are received in corresponding pivoting pin slots 23320 formed in the vertical side walls of the channel 23310. At least one pin formation swivel 23412 comprises a laterally projecting actuator boss 23414 that defines an actuator boss 23416. A swivel pin 23418 projects out of the actuator boss 23414 and is sized to translate and pivot within a swivel pin slot 23414. corresponding river 23320.

[0303] As can be seen in Figure 39, at least one swivel pin slot 23320 comprises an arcuate actuating portion 23322 and a locking displacement portion 23324 which is formed at a proximal end 23321 of the swivel pin slot

23320. Figure 39 illustrates the insertion of a cartridge 22600 into the elongate channel 23310. To install a cartridge 22600 into the elongate channel 23310, the anvil 23400 is first moved to an open position. This can be accomplished by actuation of the closure system to move the closure tube of the 3050 End Actuator (Figure 5) in a proximal DP direction. As closure tube 3050 is moved proximally, it interacts with an opening flap 23411 formed in anvil mounting portion 23410. As closure tube 3050 interacts with anvil mounting portion 23410, anvil 23400 translates proximally and begins to pivot open, which results in the formation of the swivel pin 23412 translating downward from the arcuate actuation portion 23322 of the corresponding swivel pin slot 23320 and into the proximal end 23321 of the swivel pin slots 23320 as the anvil 23400 reaches its position completely open.

[0304] When installing a suitable or compatible surgical staple cartridge 22600 into channel 23310, the anvil unlocking feature or tab 22630 is placed in engagement with contoured surface 23714 on actuation tab 23712 of the lock lock. anvil 23702. The 22600 cartridge is then moved proximally to seat the 22600 cartridge within the 22310 channel. As the 22600 cartridge is moved proximally, the 22630 anvil unlocking feature contacts the distal end 23712 of the 23702 anvil lock. and biases the 23702 anvil latch proximally an unlocking distance (UD) that to bring a proximal end 23710 of the 23706 anvil latch body into engagement with the 23414 actuator shoulder in steel. least one swivel pin formation 23412 to move the swivel pin formation 23412 into a position where the swivel pin formation 23412 can translate to the arcuate formation portion 23322 of the slot 23320 when a closing motion is applied to the anvil mounting portion 23410. Said another way, the proximal end 23710 of the anvil latch 23702 prevents the swivel pin formation 23412 from entering the latch displacement portion. 23324 formed at the proximal end 23321 of the swivel pin slot 23320 to allow the swivel pin formation 23412 to enter the arcuate actuation portion 23322 of the swivel pin slot 23320.

[0305] Figure 40 illustrates an attempt to insert an incompatible 22600X cartridge that does not have the indispensable unlocking feature or tab 22630 to move the anvil lock 23702 out of the distal locked position. If, however, the user seats the 22600X incompatible cartridge in the 23310 channel and then attempts to close the 23400 anvil, the 23700 anvil locking system will prevent the 23400 anvil from closing. For example, to close the 23400 anvil, the closing system is activated to move the closing tube (or other closing member) distally into operational contact with the 23410 anvil mounting portion of the 23400 anvil to apply closing motions thereto. The initial application of closing motions to the anvil mounting portion 23410 causes the anvil mounting portion 23410 to move downward ("downward" DL arrow in Figure 40) which results in entry of the 23410 rotating pin formations. anvil 23412 in the locking displacement portions 23324 formed in the swivel pin slots 23320. Thus, the swivel pin formations of anvil 23412 cannot translate into the arcuate actuating portion 23322 of the corresponding swivel pin slot 23320 during application of the closing motion to anvil 23400 and anvil 23400 is then prevented from closing.

[0306] Figure 41 illustrates a portion of an alternative anvil 23400' comprising an anvil mounting portion 23410' that has swivel pin formations 23412' formed thereon.

Each pivot pin formation 23412' comprises a laterally projecting actuator shoulder 23414' that defines an actuator boss 23416' that is configured to interact with an anvil locking system 23700 in the manner described above. As can be seen in Figure 41, the actuator boss 23416' is offset vertically (distance OD) from a lower surface 23415' of the anvil mounting portion 23410'. A swivel pin 23418' projects out of the actuator shoulder 23414' and is sized to translate and pivot within a corresponding swivel pin slot 23320. In this example, swivel pin 23418' has a swivel pin diameter TRD ( "trunnion pin diameter") which is approximately equal to the LW width of the actuator boss 23414'.

[0307] Figure 42 illustrates a portion of an alternative anvil 23400'' that comprises an anvil mounting portion 23410'' having swivel pin formations 23412'' formed thereon. Each pivot pin formation 23412'' comprises a laterally projecting actuator shoulder 23414'' that defines an actuator boss 23416'' that is configured to interact with an anvil locking system 23700 in the manner described above. As can be seen in Figure 42, the actuator boss 23416'' is coextensive with (e.g., not offset from) a bottom edge surface 23415'' of the anvil mounting portion 23410''. A swivel pin 23418'' projects out of the actuator shoulder 23414'' and is sized to translate and pivot within a corresponding swivel pin slot 23320. In this example, swivel pin 23418'' has a diameter TRD swivel pin which is approximately equal to the LW' width ("width") of the actuator shoulder 23414'.

[0308] Figure 43 is an end elevational view in partial cross-section of a surgical end actuator 24100 comprising an anvil 24400 that is pivotally supported over an elongated channel 24310. The anvil 24400 comprises an anvil mounting portion 24310. anvil 24410 which has rotating pin formations 24412 formed therein. Each pivot pin formation 24412 comprises a laterally projecting actuator shoulder 24414 that defines a bottom shoulder surface 24416'' that is configured to interact with an anvil locking system 24700 in the manner described above. As can be seen in Figure 44, the bottom cam surface 24416 is offset vertically (distance OD1) from a bottom surface 24415 of the anvil mounting portion 24410. A pivot pin 24418 projects out of the cam cam. actuator 24414 and is sized to translate and pivot within a corresponding swivel pin slot 24320 formed in elongated channel 24310. In this example, swivel pin 24418 has a swivel pin diameter TRD1 that is approximately equal to the width LW1 of actuator cam 24414.

[0309] Channel 20310 comprises a channel bottom 24312 and a pair of vertical side walls 24314. Channel 24310 may be coupled to an elongated drive shaft assembly 1200 (Figure 5) by a channel mounting feature 20340 which can facilitate its articulation around the articulation joint 3020 (Figure 5). Figure 45 illustrates a portion of a proximal end 24316 of channel 24310. In one example, each wall of channel 24314 has a swivel pin slot 24320 formed therein. In the illustrated arrangement, a shoulder ridge 24340 is formed on each wall of the channel 24314 so that a top surface 24342 of the shoulder ridge 24340 is coextensive with a bottom surface 24321 of the corresponding swivel pin slot 24320. Each swivel pin 24418 is received within a corresponding swivel pin slot 24320 and is free to rotate and translate therein.

[0310] Still referring to Figure 45, a portion of an anvil lock 24702 of the anvil locking system is shown

24700. The anvil latch 24702 operates in the same manner as the anvil latch 20702 described above and includes a locking body 24706 that has an actuator tab (not shown) that is formed at a distal end thereof that is configured to be contacted by an unlocking feature that protrudes proximally from a compatible cartridge. The 24702 anvil latch may be fabricated from spring steel or other suitable metal and include a 24704 proximal biasing arm which may be configured to seat in a transverse spring mounting slot (not shown) which is provided in the of the channel mount feature body (not shown). The anvil lock 24702 additionally includes an upwardly extending anvil locking tab 24710 which projects therefrom which is configured to extend above the corresponding shoulder lug 24340 and contacts a corresponding shoulder 24414 as will be described below.

[0311] Figures 45 and 46 illustrate the anvil lock 24702 in the locked position where the anvil 24400 is pivoted to an open position. This can occur when no cartridge has been inserted into channel 24310, or a non-compatible cartridge (for example, a cartridge that does not have, among other things, the proper anvil unlocking feature that is required to bias the anvil latch spring proximally- has been inserted into channel 24310. If the user unintentionally attempts to close the anvil 24400 when the anvil latch 24702 is in the distal latched position shown in Figures 45 and 46, the corresponding boss 24414 will contact the anvil 24710 and will prevent the anvil 24400 from pivoting to the closed position. Figures 47 and 48 illustrate the position of the anvil lock 24702 in the proximal unlocked position where the anvil locking tab 24710 is positioned proximal to the shoulder 24414 to allow the shoulder 24414 to pivot to the closed position.

[0312] Figure 49 is an end elevational view in partial cross-section of a surgical end actuator 24100 comprising an anvil 24400 that is pivotally supported over an elongated channel 24310. Anvil 24400' comprises an anvil 24400 that is pivotally supported over an elongated channel 24310. - anvil mounting assembly 24410' which has swivel pin formations 24412' formed therein. Each pivot pin formation 24412' comprises a laterally projecting actuator shoulder 24414' that defines a bottom shoulder surface 24416' that is configured to interact with an anvil locking system 24700' in the manner described above. As can be seen in Figure 50, the bottom shoulder surface 24416' is coextensive with a bottom surface 24415' of the anvil mounting portion 24410'. A swivel pin 24418' projects out of the actuator shoulder 24414' and is sized to translate and pivot within a corresponding swivel pin slot 24320' formed in the elongated channel 24310'. In this example, swivel pin 24418' has a swivel pin diameter DRT2 that is smaller than the LW2 width of actuator shoulder 24414'.

[0313] Channel 20310' comprises a channel bottom 24312' and a pair of vertical side walls 24314'. The channel 24310' may be coupled to an elongated drive shaft assembly 1200 (Figure 5) by a channel mounting feature 20340 which can facilitate its pivoting around the pivot joint 3020 (Figure 5). Figure 51 illustrates a portion of a proximal end 24316' of channel 24310'. In one example, each channel wall 24314' has a swivel pin slot 24320' formed therein. In the illustrated arrangement, a shoulder lug 24340' is formed in each channel wall 24314' so that a top surface 24342' of shoulder lug 24340' is offset vertically from a bottom surface 24321' of the slot. corresponding swivel pin 24320' an OSD offset distance ("offset distance"). The OSD offset distance may be approximately equal to a distance TSD between the swivel pin 24418' and the lower shoulder surface 24416'. See Figure 50. Each swivel pin 24418' is received within a corresponding swivel pin slot 24320' and is free to rotate and translate therein.

[0314] Still referring to Figure 51, a portion of an anvil lock 24702' of the anvil locking system 24700' is shown. The anvil latch 24702' operates in the same manner as the anvil latch 20702 described above and includes a locking body 24706' which has an actuator tab (not shown) formed at a distal end thereof which is configured to be placed in contact by an unlocking feature that protrudes proximally from a compatible cartridge. The 24702' anvil latch may be fabricated from spring steel or other suitable metal and include a 24704' proximal bias arm which may be configured to seat in a transverse spring mounting slot (not shown) provided in the body portion. of the channel mount feature (not shown). The anvil latch 24702' additionally includes an upwardly extending anvil locking tab 24710' protruding therefrom which is configured to extend above the corresponding shoulder lug 24340' and contacts a corresponding boss 24414' as described above.

[0315] Figure 51 illustrates the anvil lock 24702' in the locked position where the anvil 24400 is pivoted to an open position. This can occur when no cartridge has been inserted into the channel or a non-compatible cartridge (for example, a cartridge that does not have, among other things, the proper anvil unlocking feature that is required to bias the anvil lock spring proximally. ) was inserted into channel 24310'. Should the user unintentionally attempt to close the anvil 24400' when the anvil lock 24702' is in the distal locked position shown in Figure 45, the corresponding shoulder 24414' will contact the anvil locking tab 24710' and prevent the anvil 24400' pivot to closed position. After a compatible surgical staple cartridge has been loaded into the 24100' end actuator, the 24702' anvil latch will tilt to the unlocked position (see, for example, Figure 47) and the 24400' anvil will be free to pivot to the closed position.

[0316] Figure 52 represents a portion of a surgical end actuator 24100'' that comprises an anvil 24400'' that is pivotally supported on an elongated channel 24310''. The anvil 24400'' comprises an anvil mounting portion 24410'' having swivel pin formations 24412'' formed therein. As can be seen in Figures 53 and 54, each swivel pin formation 24412'' comprises a laterally projecting actuator shoulder 24414'' that defines a bottom shoulder surface 24416'' that is configured to interact with a 24700'' anvil locking system in the manner described above. As can be seen in Figure 53, actuator cam 24414'' as well as bottom cam surface 24416'' of actuator cam 24414'' are situated at an angle to an end actuator geometry axis. (EA) as well as a bottom edge 24419'' of anvil mounting portion 24410'' and/or bottom 24312'' of channel 24310''. As further illustrated in Figure 53, the bottom cam surface 24416'' is parallel to a cam axis LBA ("lobe axis") which is situated at a cam angle LA ("lobe angle") with respect to the axis geometry of the EA end actuator. A swivel pin 24418'' projects out of the actuator shoulder 24414'' and is sized to translate and pivot within a corresponding swivel pin slot 24320'' that is formed in the elongated channel 24310''. See Figure 55. In this example, swivel pin 24418'' has a swivel pin diameter DRT3 that is approximately equal to the LW3 width of actuator shoulder 24414''.

[0317] Referring to Figure 55, channel 24310'' comprises a channel bottom 24312'' and a pair of vertical side walls 24314''. Channel 24310'' may be coupled to an elongated drive shaft assembly 1200 (Figure 5) by a channel mounting feature 20340 which can facilitate its pivoting around pivot joint 3020 (Figure 5) in the various ways described in present document. Figure 55 illustrates a portion of a proximal end 24316'' of channel 24310''. In one example, each channel wall 24314'' has a swivel pin slot 24320'' formed therein. In the arrangement illustrated, a shoulder ridge 24340'' is formed on each wall of the channel 24314'' so that a proximal surface portion 24344" of a top surface 24342'' of the shoulder ridge 24340'' is coextensive. - tensile with a bottom surface 24321'' of the corresponding swivel pin slot 24320''. In the illustrated arrangement, the bottom surface 24321'' of the swivel pin slot 24320'' is approximately parallel to the geometric axis of the end actuator EA and/or the bottom 24312'' of the channel 24310''. As can be seen in Figure 56, an inclined portion 24346'' of the top surface 24342'' extends distally from the proximal surface portion 24344'' at a TSA angle and terminates in a horizontal distal surface portion 24348'' . In one arrangement, for example, the distal surface portion 24348'' is approximately parallel to the axis of end actuator EA and/or the bottom 24312'' of channel 24310'' and angle TSA = angle LA. However, the TSA angle may be different from the LA angle in other modalities. Each swivel pin 24418'' is received within a corresponding swivel pin slot 24320'' and is free to rotate and translate therein.

[0318] With reference to Figures 55 and 56, a portion of an anvil lock 24702'' of an anvil locking system 24700'' is shown. The anvil latch 24702'' operates in the same manner as the anvil latch 20702 described above and includes a locking body 24706'' which has an actuator tab (not shown) formed at a distal end thereof which is configured to be contacted by an unlocking feature that protrudes proximally from a compatible surgical staple cartridge. The 24702'' anvil latch may be fabricated from spring steel or other suitable metal and include a 24704'' proximal bias arm which may be configured to seat in a cross spring mounting slot (not shown) that is provided on the body portion of a channel mount feature (not shown). The anvil latch 24702'' further includes an upwardly extending anvil locking tab 24710'' protruding therefrom and configured to extend above the distal surface portion 24348'' of the corresponding shoulder lug. 24340'' and be equal to or level with the proximal surface portion 24344'' portion of the shoulder ridge 24340''.

[0319] Figure 55 illustrates the 24702'' anvil lock in the distal locked position with the 24400'' anvil pivoted to an open position. This can occur when no surgical staple cartridge has been inserted into channel 24310'' or a non-compatible surgical staple cartridge (e.g. a surgical staple cartridge that does not have, among other things, the proper anvil unlocking feature). which is required to propose the anvil lock 24702” proximally) was inserted into the channel 24310''. When the 24702” anvil lock is in this position, the 24418” anvil swivel pins are located at the proximal end of their respective 24320” swivel pin slot and the 24416” bottom shoulder surface of at least a boss 24414” rests on the proximal surface portion 24344” of the corresponding boss boss 24340” as well as on the anvil locking tab 24710”. If the user unintentionally tries to close the anvil 24400’’

when the 24702'' anvil lock is in the distal locked position shown in Figures 52 and 55, the 24710” anvil lock tab will prevent the 24414” shoulder from pivoting down to the 24346” ramp surface portion of the 24340” shoulder that prevents the 24400” anvil from pivoting to the closed position. See Figure 52. After a compatible surgical staple cartridge has been loaded into the 24100'' End Actuator, its anvil locking feature will bias the 24702'' anvil lock proximally to the unlocked position. See Figures 56 and 57. When anvil lock 24702”' is in the proximal unlocked position, anvil lock tab 24710”' is locked proximal to ramp surface 24346”' on shoulder boss 24340”' to allow for this. the shoulder 24414”' pivots down on it, which results in the closing of the anvil 24400”'.

[0320] Figure 58 represents a proximal portion of another anvil 24400"' which is configured to be pivotally supported in an elongated channel 24310"' which is similar to channel 24310"' except for the differences discussed below. The anvil 24400"' comprises an anvil mounting portion 24410"' which has swivel pin formations 24412"' formed therein. Each rotating pin formation 24412''' comprises a laterally projecting actuator shoulder 24414''' that defines a bottom shoulder surface 24416''' which is configured to interface with an anvil locking system 24700'' of the way described above. The actuator shoulder 24414"' as well as the bottom shoulder surface 24416"' of the actuator shoulder 24414"' are located at an angle that is equal to the angle LA described above with respect to the actuator shoulder 24414''. A swivel pin 24418''' projects out of the actuator shoulder 24414''' and is sized to translate and pivot within a corresponding swivel pin slot 24320''' that is formed in the elongated channel 24310'''. See Figure 59. In this example, swivel pin 24418''' has a swivel pin diameter DRT4 that is approximately equal to the LW4 width of actuator shoulder 24414'''.

[0321] As can be seen in Figure 59, the channel 24310''' comprises a channel bottom 24312''' and a pair of vertical side walls 24314'''. The 24310''' channel can be coupled to an elongated drive shaft assembly 1200 (Figure 5) by a channel mount feature 20340 that can facilitate its pivoting around the articulation joint 3020 (Figure 5). 5). Figure 59 illustrates a portion of a proximal end 24316''' of channel 24310'''. In one example, each channel wall 24314''' has a swivel pin slot 24320''' formed therein. In the illustrated arrangement, a shoulder lug 24340''' is formed on each channel wall 24314''' so that a top surface 24342''' of the shoulder lug 24340''' is offset vertically from a bottom surface 24321''' of the corresponding swivel pin slot 24320''' an OSD1 offset distance ("offset distance"). The displacement distance OSD1 can be approximately equal to a distance between the swivel pin 24418''' and the bottom shoulder surface 24416'''. In the illustrated arrangement, the top surface 24342''' of the shoulder ridge 24340''' is identical to the top surface 24342'' of the shoulder ridge 24340'' and includes a proximal portion 24344''' that is parallel to the bottom surface 24321''' of the swivel pin slot 24320''' as well as an inclined surface 24346''' and a distal surface 24348'''.

[0322] The 24700'' anvil locking system works in the same way to prevent the 24400''' anvil from closing. When no cartridge is present in channel 24310”' or a non-compatible cartridge (e.g. a cartridge without adequate anvil unlocking feature to bias the anvil latch spring proximally) has been inserted into channel 24310”', the anvil lock tab 24710”' is in its most distal locked position preventing the corresponding actuator shoulder 24414”' from pivoting down over the ramped surface 24346”' thus keeping the anvil 24400”' in the open position.

After a compatible surgical staple cartridge has been loaded into the 24100'' End Actuator, its anvil locking feature will bias the 24702'' anvil lock proximally to the unlocked position. When the anvil lock 24702'' is in the proximal unlocked position, the anvil locking tab 24710” is locked proximal to the ramped surface 24346”' on the shoulder boss 24340''' to thereby allow the shoulder 24414'” to pivot down on it, which results in the closing of the anvil 24400”'.

[0323] Figures 60 and 61 illustrate another 24400 A anvil that is identical in construction and operation to the 24400 anvil described above, except that the 24412 A rotating pin formation is offset vertically from a lower edge 24415 A of an anvil mounting portion 24410A of anvil 24400A. Figure 62 illustrates another anvil 24400B that is identical in construction and operation to the anvil 24400' described above, except that the swivel pin formation 24412B is offset vertically from a lower edge 24415B of an anvil mounting portion. 24410B of the anvil 24400B.

[0324] The examples depicted in Figures 41 to 62 use swivel pin formations that comprise various shapes and configurations of cam structures that serve to interact with an anvil locking feature such that the interaction between the anvil locking feature anvil and corresponding cam structure serves to facilitate positioning of the anvil swivel pins within their respective swivel pin slots. This positioning of the landing structures allows the anvil to close by applying closing movements to it when a compatible surgical staple cartridge is loaded inside the end actuator. In cases where an incompatible surgical staple cartridge is loaded into the end actuator, the anvil lock feature will retain the corresponding swivel pin formation in a position where the anvil will not be able to close even upon application of a closing movement to it. Thus, the initial positions of the swivel pin formations prevent closure, but loading a suitable or compatible surgical staple cartridge into the canal changes the positions of the swivel pin formations allowing closure to occur. The various cam features described here are also generally more robust than previous swivel pin arrangements, which can lead to better reliability.

[0325] Figures 63 to 69 represent a surgical end actuator 25300 that can be used, for example, in connection with the energized surgical instrument 1010 described above. The surgical end actuator 25300 comprises an anvil 25400 that is pivotally supported over an elongated channel 25310 that is configured to operatively support a cartridge of surgical staples 25600. The anvil 25400 is movable between an open position and a closed position through interaction. with an axially movable closing member in the various ways disclosed herein. In the illustrated example, the anvil 25400 comprises an anvil body 25402 and an anvil mounting portion 25410. The anvil mounting portion 25410 comprises a pair of laterally extending pivoting pins 25412 that are operatively received within the slots of the anvils. corresponding pivot pins provided on the vertical side walls 25314 of channel 25310 in the various ways disclosed herein. As discussed above with respect to the end actuator 1300, the anvil 25400 can be pivoted between an open position and a closed position by interacting with a closing tube of the end actuator 3050 in the various ways described herein. For example, the end actuator closure tube 3050 can be axially moved by actuation of a closure trigger 1032 of the surgical instrument 1010. In other arrangements, the end actuator 25300 and drive shaft assembly to which it is attached can operationally interface with a robotic system as described in detail in many of the references which have been incorporated herein by reference. In such applications, the closing tube of the 3050 end actuator can be axially advanced and retracted through the actuation of a robotic system closing control system.

[0326] In the illustrated arrangement, distal movement of the end actuator closure tube 3050 causes a distal end 3051 of the end actuator closure tube 3050 to operatively interact with a cam surface 25411 that is formed on the anvil mounting portion 25410 to move the anvil 25400 to a closed position. When the 3050 End Actuator Closing Tube is axially retracted in the proximal direction, the 3050 End Actuator Closing Tube can be configured to interact with various formations, bosses, or tabs to apply an opening motion to the 25400 anvil. More details can be found in various other references which have been incorporated herein by reference.

[0327] The elongated channel 25310 can be coupled to an elongated drive shaft assembly 1200 (Figure 5) by a channel mounting feature 20340 which can facilitate its pivoting around the pivot joint 3020 (Figure 5) in various ways described in this document. The illustrated example also includes a trigger member 20500 (FIG. 20) that is attached to a distal end of a trigger member beam 1900 (Figure 5) and is configured to operationally interface with a cam assembly on a 25600 surgical staple cartridge that has been loaded into channel 25310. To ensure that a compatible surgical staple cartridge

25600 was loaded into the 25300 End Actuator prior to closing the 25400 Anvil, the End Actuator uses a 25700 Closing Locking System. In the illustrated example, the 25700 Closing Locking System is configured to prevent distal movement of the 3050 End Actuator Closing Tube unless a 25600 compatible cartridge has been properly seated within the 25310 channel. In one example, the 25700 Closing Lock System comprises a 25702 Closing Latch that is configured to move between a locked position and an unlocked position in response to the installation of a compatible 25600 surgical staple cartridge in it. Figures 65 to 69 illustrate a form of a locking latch 25702 that may be manufactured from spring steel or other suitable metal and include a body portion 25706 that is pivotally secured to the body portion 20342 of the channel mount feature. 20340 by a 25709 pivot pin that extends through a 25707 pivot hole in the 25706 body portion. The 25702 closing latch additionally includes a 25704 proximal bias arm that can be configured to seat in a slot. (not shown) which is provided in the body portion 20342 of the channel mounting feature 20340. Such an arrangement serves to bias the closing latch 25702 downwardly within the channel 25310.

[0328] As can be more particularly seen in Figures 65 and 66, in the illustrated example, the closing latch 25702 additionally includes a locking feature 25710 that projects from the bottom of the body portion 25706 and extends laterally towards outside. As illustrated in Figure 65, when the 25702 Closing Latch is in the locked position, the 25710 Locking feature is positioned to block the distal advancement of the 3050 End Actuator Closing Tube. When the 25702 Closing Latch is in unlocked as shown in Figure 66, the 25710 locking feature is moved away from the locked position to allow distal advancement of the end actuator closing tube

3050

[0329] Returning to Figure 67, the lock latch 25702 additionally includes an actuator portion 25712 that extends proximally to be engaged by a lock release feature 25630 formed at a proximal end 25604 of a cartridge surgical staple cartridge 25600. In at least one arrangement, the surgical staple cartridge 25600 comprises an elongate cartridge body 25602 that is sized to be removably seated in the elongate channel 25310. The cartridge body 25602 includes a cartridge 25608 that extends from a proximal end portion 25604 to a distal end portion 25606 (Figure 64) of cartridge body 25602. Cartridge body 25602 further comprises a cartridge platform surface 25610 that faces a lower clamp forming surface 25404 of anvil 25400 when cartridge 25600 is seated in channel 25310 and anvil 25400 is pivoted to a closed position gives. Although not shown in Figure 67, the surgical staple cartridge 25600 may have a plurality of (generally three) rows of surgical staple pockets on either side of the cartridge slot 25608 that open through the cartridge platform surface.

25610. Each staple pocket may have a staple driver (not shown) associated with it that supports a surgical staple or fastener (not shown) thereon. In at least one example, the cartridge body 25602 is molded from a polymeric material with the staple pockets molded or machined therein. In one arrangement, the staple pockets also open through a bottom of the 25602 cartridge body to facilitate the installation of triggers and fasteners in their respective pockets. After the drivers and fasteners are inserted into their respective staple pockets, a 25620 cartridge tray is attached to the bottom of the 25602 cartridge body. When installed, the 25620 cartridge tray can, among other things, prevent drivers and fasteners fall out of the bottom of cartridge body 25602 during handling and installation of cartridge 25600 into elongate channel 25310. As discussed above in connection with cartridge 20040, cartridge 25600 operatively supports a cam assembly therein. The cam assembly comprises a series of spaced-apart cam members that are configured to move axially within corresponding cam slots 25609 formed on either side of cartridge slot 25608 in cartridge body 25602. Cam slots 25609 are aligned with corresponding rows of drivers on cartridge body 25602 to facilitate cam contact with a corresponding cam member as the cam assembly is driven through the staple cartridge 25600 from an initial position within the cam portion. proximal end 25604 of cartridge body 25602 to an end position within the distal end portion

25606.

[0330] Figure 63 and 68 illustrate the 25300 Surgical End Actuator without a Surgical Staple Cartridge installed in it. As can be seen in Figure 68, the proximal biasing arm 25704 has biased the closing latch 25702 down into the 25310 channel, which results in the movement of the blocking feature 25710 in blocking alignment with the distal end 3051 of the closing tube of the 3050 end actuator (locked position). If the user activates the closing system to move the closing tube,

When the 3050 End Actuator is pulled distally, the 25710 Lockout feature will block the distal advancement of the 3050 End Actuator Closing Tube, thus preventing an application of closing motions to the 25400 Anvil. Returning to Figure 67, in In at least one arrangement, the staple cartridge 25600 includes an anvil unlocking feature or tab 25630 that projects proximally from the cartridge body 25602 and is aligned to unlockly engage the actuation tab 25712 which is formed at the distal end of the 25702 closing latch when the 25600 cartridge is operatively installed in the 25310 elongated channel. In one example, the 25630 unlocking feature has a somewhat sloped surface 25632 that is configured to interact operationally. ally with an angled surface 25713 on the actuation tab 25712 so that when the angled surface 25632 and the angled surface 25713 are brought into engagement, the closing latch 2570 2 is pivoted in an upward direction. When the 25702 Closing Latch is pivoted up to the unlocked position, the 25710 Interlocking feature is no longer in interlocking alignment with the 3050 End Actuator Closing Tube. See Figure 66.

[0331] Figures 64 and 69 depict the 25300 Surgical End Actuator with a 25600 Compatible Surgical Staple Cartridge operationally installed in the 25310 elongated channel. 25602 staple cartridge made contact with angled surface 25713 (shown in Figure 68) on actuating tab 25712 on closing latch 25702 to bias closing latch 25702 to the unlocked position. When in this position, the user can advance the 3050 End Actuator Closing Tube distally to apply closing motions to the 25400 Anvil. Should the user attempt to install an improper cartridge that does not have the 25630 unlocking feature in a proper A similar feature designed to unlock the 25702 Closing Latch, the user will not be able to distally advance the 3050 End Actuator Closing Tube to close the 25400 Anvil.

[0332] Figures 70 and 71 illustrate a surgical end actuator 25300' comprising an anvil 25400' that is pivotally supported over a channel 25310' and is substantially identical to the end actuator 25300' described above, except that the 25700' Closing Latch System uses a different 25702' Closing Latch that is configured to interact with an unlocking feature provided on a 25650' Cam Assembly on a 25600' Surgical Staple Cartridge. As can be seen in Figures 70 and 71, the locking latch 25702' comprises an elongate body 25706' which has a tapered actuator flap portion 25712' at its distal end. The body 25706' is pivotally secured to the channel mounting feature 20340 and a proximal bias arm 25704' biases the closing latch 25702' within the channel 25310'.

[0333] Figure 72 illustrates a surgical staple cartridge 25600' comprising an elongated cartridge body 25602' that is sized to be removably seated in the elongate channel 25310'. Cartridge body 25602' includes a cartridge slot 25608' extending from a proximal end portion 25604' to a distal end portion of cartridge body 25602'. Cartridge body 25602' further comprises a cartridge platform surface 25610' which faces a lower staple forming surface 25404' of anvil 25400' when cartridge 25600' is seated in channel 25310' and anvil 25400 ' is pivoted to a closed position.

Although not shown in Figure 72, the surgical staple cartridge 25600' may have a plurality of (generally three) rows of surgical staple pockets on either side of the cartridge slot 25608' that open through the cartridge platform surface. 25610'. Each staple pocket may have a staple driver (not shown) associated therewith that supports a surgical staple or fastener (not shown) thereon.

In at least one example, the cartridge body 25602' is molded from a polymeric material with the staple pockets molded or machined therein.

In one arrangement, the staple pockets also open through a bottom of the 25602' cartridge body to facilitate installation of the triggers and fasteners into their respective pockets.

After the drivers and fasteners are inserted into their respective staple pockets, a 25620' cartridge tray is attached to the bottom of the 25602' cartridge body. When installed, the cartridge tray 25620' can, among other things, prevent the drivers and fasteners from falling out of the bottom of the cartridge body 25602' during handling and installation of the cartridge 25600' in the elongated channel 25310'. A cam assembly 25650' is operatively supported on cartridge body 25602'. In at least one arrangement, cam assembly 25650 comprises a series of spaced apart cam members 25652' which are configured to move axially within corresponding cam slots 25609' which are formed on either side of cartridge slot 25608' in cartridge body 25602. Cam slots 25609' align with corresponding rows of drivers on cartridge body 25602' to facilitate cam contact with a corresponding cam member 25652' as cam assembly 25650 ' is driven through the staple cartridge 25600' from a starting position within the proximal end portion 25604' of the cartridge body 25602' to an ending position within the distal end portion.

In at least one example, cam assembly 25650' includes a locking unlocking feature or tab 25660' that projects proximally from cam assembly 25650' and is aligned to unlockly engage actuation tab 25712' which is formed at the distal end of the closing latch 25702' when the cartridge 25600' is operatively installed in the elongate channel 25310' and the cam assembly 25650' is in its unfired home position within the cartridge 25600'.

[0334] Again with reference to Figure 71, in one example, the unlocking feature 25660' has a tapered nose portion 25662' which is configured to operatively interact with the actuation tab 25712' so that when the tapered nose portion 25662' is placed in engagement with actuation tab 25712', closing latch 25702' is pivoted upwards. When the 25702' Closing Latch is pivoted up to the unlocked position, a 25710' Latching feature on the 25702' Closing Latch is no longer in blocking alignment with the End Actuator Closing Tube

3050

[0335] As can be seen in Figure 72, cartridge body 25602' may additionally include a locking safety 25670' protruding proximally from a proximal end of cartridge body 25602' and adjacent to the nose portion tapered 25662'. An upper surface 25672' of the locking security 25670' is positioned at an angle to correspond with the tapered nose portion 25662' but when the cam assembly 25650' is in its most proximal home position, the tapered nose portion 25662' protrudes proximally beyond the end of the 25670' locking safety.

[0336] Figure 70 illustrates an initial insertion of a 25600' compatible unfired surgical staple cartridge into channel 25310'. As can be seen in Figure 70 the tapered nose portion 25662'

made initial contact with actuator tab portion 25712' over closing latch 25702'. The 25702' Closing Latch remains biased downward to a locked position in which the 25710' locking feature of the 25702' Closing Latch is in locking alignment with the 3051 distal end of the Closing Tube 25702'. end actuator 3050. As cartridge 25600' is advanced further proximally to a seated position within channel 25310', tapered nose portion 25662' on cam assembly 25650' lifts actuation tab 25712' up above 25672' angled top surface of the 25670' locking safety to allow the 25702' locking latch to pivot to the unlocked position in which the 25710' locking feature is no longer in locking alignment with the 3051 distal end of the 3050 End Actuator Closing Tube. When in this position, the user can advance the 3050 End Actuator Closing Tube to apply closing motions to the 25400' anvil. Thus, in this mode, the closing latch system 25700' is actuated by the cam assembly 25650', but only when the cam assembly 25650' is in a non-triggered home position.

[0337] Figure 73 illustrates the insertion of a 25600X staple cartridge where its cam assembly is not in a more proximal unfired position. This can occur when the user tries to use the 25600X staple cartridge that was previously used, for example. Since the cam assembly is not in its unfired home position, the tapered nose portion is absent to begin biasing the closing latch 25702' to an up position above the closing safety 25670'. When the 25600X cartridge is fully seated in the channel 25310', the action tab 25712' of the closing latch 25702' is positioned under a lower locking surface 25674'. The 25702' Closing Latch remains in the latched position in which its 25710' blocking feature is in blocking alignment with the 3051 distal end of the 3050 End Actuator Closing Tube. When the 3050 End Actuator Closing Tube is used to close the 25400' Anvil, the 3051 Distal End will contact the 25710' Lockout Feature and the 25670' Closing Safety will additionally prevent the 25702 Closing Latch. ' Pivot up to an unlocked position under closing load.

[0338] Figures 74 and 75 illustrate a 25300'' surgical end actuator comprising a 25400'' anvil that is pivotally supported in a 25310'' channel and is substantially identical to the 25300' end actuator described above . The 25300’’ End Actuator uses a 25700’’ Closing Latch System that comprises a 25702’’ Closing Latch. As can be seen in Figure 76, the locking latch 25702'' comprises an elongate body 25706'' that has an actuator tab portion 25712'' at its distal end. The body 25706'' includes a lower spring arm 25720'' which is mounted inside the channel 25310''. The lower spring arm 25720'' is mounted so as to apply a downward biasing force to the closing latch 25702'', which will be discussed below. As will be discussed in more detail below, the 25702'' Closing Latch additionally includes a 25710'' vertically extending anvil locking tab that is configured to interlock in a locked manner with a 25414 locking pin. '' which is formed in an anvil mounting portion 25410'' of anvil 25400''. In addition, the closing latch 25702'' comprises a proximal biasing spring 25704'' that serves to bias the closing latch 25702'' in the distal direction DD (Figure 76). As can be seen in Figure 74, the elongated channel

25310'' can be coupled to a 1200 elongated drive shaft assembly (Figure 5) by a 20340 channel mount feature that can facilitate its pivoting around the 3020 pivot joint (Figure 5) in various ways. described here. As can be seen in Figure 76, the proximal bias spring 25704” is configured to be seated in the transverse slot 20343 in the body portion 20342 of the channel mounting feature 20340.

[0339] Similar to the closure of the 25400' anvil discussed above, the distal movement of an end actuator closure tube causes a distal end of the end actuator closure tube to operatively interact with a cam surface 25411" formed over an anvil mounting portion 25410" of anvil 25400" to move anvil 25400" to a closed position. When the end actuator closing tube is axially retracted in the proximal direction, the end actuator closing tube can be configured to interact with various formations, protrusions or tabs to apply an opening motion to the 25400' anvil '. More details can be found in various other references which have been incorporated herein by reference.

[0340] Figure 77 illustrates a surgical staple cartridge 25600'' comprising an elongated cartridge body 25602'' that is sized to be removably seated in the elongate channel 25310'. Cartridge body 25602'' includes a cartridge slot 25608'' that extends from a proximal end portion 25604'' to a distal end portion of cartridge body 25602''. Cartridge body 25602'' further comprises a cartridge platform surface 25610'' which faces a lower staple forming surface 25404'' of anvil 25400'' when cartridge 25600'' is seated in channel 25310 ' and anvil 25400' is pivoted to a closed position.

Although not shown in Figure 77, the 25600'' surgical staple cartridge may have a plurality of (generally three) rows of surgical staple pockets on either side of the 25608'' cartridge slot that open through the 25610 cartridge platform surface. ''. Each staple pocket may have a staple driver (not shown) associated with it that supports a surgical staple or fastener (not shown) thereon.

In at least one example, the cartridge body 25602' is molded from a polymeric material with the staple pockets molded or machined therein.

In one arrangement, the staple pockets also open through a bottom of the 25602'' cartridge body to facilitate installation of triggers and fasteners in their respective pockets.

A cam assembly 25650'' is operatively supported on cartridge body 25602''. In at least one arrangement, the cam assembly 25650'' comprises a series of spaced apart cam members 25652'' that are configured to move axially within corresponding cam slots 25609'' that are formed in each side of cartridge slot 25608' in cartridge body 25602''. The 25609'' cam slots are aligned with the corresponding rows of drivers on the 25602'' cartridge body to facilitate cam contact with a corresponding 25652'' cam member as the 25650' cam assembly ' is driven through the staple cartridge 25600'' from an initial position within the proximal end portion 25604'' of the cartridge body 25602'' to an end position within the distal end portion.

In at least one example, cam assembly 25650' includes a locking unlocking feature or tab 25660'' that projects proximally from cam assembly 25650'' and is aligned to unlockly engage actuation tab 25712 '' which is formed at the distal end of the 25702'' Closing Latch when the 25600'' Surgical Staple Cartridge is operatively installed in the 25310'' elongated channel and the cam assembly

25650’’ is in its unfired home position inside the 25600’’ cartridge.

[0341] Again with reference to Figure 77, in one example, the unlocking feature 25660'' has a tapered nose portion 25662'' which is configured to operatively interact with the actuating tab 25712'' so that when the nose 25662'' is placed in engagement with actuating tab 25712'', closing latch 25702'' is moved upward against a downward bias force established by lower spring 25720''. When the 25702'' closing latch is pivoted up to the unlocked position, the 25710'' anvil locking tab on the 25702'' closing latch is no longer in locking alignment with the 25414 locking pin. '' on anvil mounting portion 24410''.

[0342] Figure 74 illustrates an initial insertion of a compatible 25600'' unfired surgical staple cartridge into channel 25310''. As can be seen in Figure 74, the tapered nose portion 25662'' of the cam assembly 25650'' has not yet interacted with the actuator tab portion 25712'' on the closing latch 25702''. The 25702'' Closing Latch remains biased downward to a locked position where the 25710'' Anvil Locking Tab of the 25702'' Closing Latch is in locking alignment with a locking pin. 25414'' over the anvil mounting portion 25410'' of the anvil 25400''. As the 25600'' Surgical Staple Cartridge is advanced further proximally to a seated position within the 25310'' channel, the tapered nose portion 25662'' on the cam assembly 25650'' contacts the actuation 25712'' and biases the closing latch 25702'' upward to an unlocked position where the anvil locking tab 25710'' is no longer aligned with the anvil locking pin 25414''.

When in this position, the user can close the 25400'' anvil by advancing the end actuator closing tube distally and applying closing movements to the 25400'' anvil. Thus, in this mode, the closing locking system 25700'' is actuated by the cam assembly 25650'', but only when the cam assembly 25650'' is in a non-triggered home position. Upon removal of the Surgical Staple Cartridge 25600'' from the channel 25310'', the lower spring 25720'' on the Closing Latch 25702'' will bias the Closing Latch 25702'' downwards back to its locked position. that anvil locking tab 25710'' is in lock alignment with locking pin 25414'' on anvil 25400''.

[0343] Figure 78 illustrates the insertion of a 25600X'' staple cartridge that has a cam assembly in it that is not in a more proximal unfired position. Since the cam assembly is not in its unfired home position, the tapered nose portion is absent to bias the closing latch 25702'' up to the unlocked position. Closing latch 25702' remains in the latched position where its anvil latch tab 25710'' is in locking alignment with anvil latch pin 25414'' on anvil 25400''. If the user unintentionally tries to close the anvil 25400'', the anvil locking pin 25414'' will contact the anvil locking tab 25710'' on the closing latch 25702'' and will prevent the anvil 25400'' from pivoting. to the closed position.

[0344] Figures 79 to 83 illustrate an alternative cartridge nose assembly 25800 that can be used with any of the cartridges and channel arrangements disclosed in the present invention to provide another mechanism for ensuring that a cartridge of surgical staples that is inserted into the end actuator channel is compatible with the end actuator and to provide the user with another visual indicator that the cartridge has fired. For example, the 25800 Cartridge Nose Assembly can be used with the 25600 Cartridge and 25310 Channel of the 25300 End Actuator (Figure 64). In the illustrated arrangement, cartridge nose assembly 25800 comprises a nose assembly body 25802 that is movably coupled to a distal end 25606 of cartridge body 25602. As can be seen in Figures 81 and 82, the end portion 25606 of cartridge body 25602 comprises a distally extending tapered portion 25605 which is adapted to be received within a complementary shaped nose notch 25804 in the nose assembly body 25802. In addition, the nose assembly body 25802 is configured with axial alignment features (not shown) that can be slidably supported in 25607 axial grooves provided in the 25606 distal end portion of the 25602 cartridge body.

[0345] As can be seen in Figures 83 and 84, a nose detent locking arm 25810 extends proximally from an upper portion of the nose assembly body 25802 into a locking cavity 25680 formed in the nose assembly body 25802. cartridge 25602. The nose assembly body 25802 is axially movable from a locked position shown in Figures 81 and 83 to an unlocked position shown in Figures 82 and 84. When the nose assembly body 25802 is in the unlocked position, a retainer 25812 which is formed at a proximal end of retainer lock arm 25810 engages retainer pin 25682 which is formed over distal end portion 25606 of cartridge body 25602 to retain cartridge nose assembly 25800 at distal end 25606 of the 25602 cartridge body.

[0346] Referring now to Figures 81 and 82, the nose assembly body 25802 further comprises proximally extending nose tab portions 25820 which are sized to frictionally engage corresponding distally extending channel protrusions 25317 formed at a distal end 25315 of channel 25310 to retain nose assembly 25800 in the "locked position" proximally forward. As can be seen in Figures 83 and 84, the nose assembly body 25802 may additionally include an integral spring arm 25830 that is configured to interact with a spring pin 25684 that is formed over the tapered portion that extends distally. 25605 of the 25602 cartridge body. The 25830 spring arm applies a distal biasing force (BF, "biasing force") to the 25800 cartridge nose assembly to increase the friction force assembly between the nose flap portions 25820 and channel bosses 25317 to retain the 25800 cartridge nose assembly in the locked position.

[0347] In operation, the 25800 cartridge nose assembly is in the locked position when the 25600 cartridge is in its unfired state and is ready to be installed in the 25310 channel. To install the 25600 unfired cartridge in the end actuator 25300, cartridge body 25602 is placed in channel 25310 and then advanced proximally therein to engage channel protrusions 25317 with nose tab portions 25820 as shown in Figures 81 and

82. As discussed above, when the 25600 cartridge is unfired, the 25650 cam assembly is at its most proximal home position. During the firing process, the cam assembly 25650 is driven on the cartridge body 25602 to its most distal position therein. When the 25650 cam assembly reaches its most distal position, a center body portion 25651 of the 25650 cam assembly contacts the 25800 cartridge nose assembly with a sufficient amount of force to overcome the frictional forces FF which retains the 25800 cartridge nose assembly in the locked position and moves the 25800 cartridge nose assembly axially to the unlocked position.

Alternatively, the user can disengage the nose assembly from the 25800 cartridge by pulling it distally to the unlocked position. After the 25800 cartridge nose assembly is moved to the unlocked position, the 25600 cartridge can be removed from the 25310 elongated channel. In addition, the 25800 distally extending cartridge nose assembly can provide the user with a visual indication of that the cartridge has been fired (spent).

[0348] Figures 85 and 86 illustrate a portion of a 26300 surgical end actuator that uses a 26120 trigger member that can be configured to be advanced distally by a rotation-actuated trigger system or a powered trigger system. axial chalk (not driven by rotation). In particular, the trigger member 26120 may be used in connection with any of the various end actuator arrangements and trigger system configurations disclosed herein, as well as in connection with the end actuator and trigger system configurations. triggers described in the various references incorporated by reference into the present invention.

[0349] As can be seen in Figures 85 and 86, the triggering member 26120 comprises a triggering member body 26122 that includes a triggering member locking system 26140 comprising a triggering member locking system 26142 that is secured in place. pivotally to the firing member body 26122. The firing member locking 26142 comprises a locking body 26144 comprising a pair of legs 26146 which engage the firing member body 26122 and are pivotally secured thereto. . The 26144 locking body additionally includes a 26148 slider lock that is configured to contact a cam slider or a 26650 cam assembly that is operatively supported on a staple cartridge (not shown). Figure 85 illustrates the triggering member 26120 in its most proximal starting position. As can be seen in Figures 85 and 86, a trigger lock orifice 26315 is provided through a bottom portion 26312 of an elongate channel 26310 of the end actuator 26300. Lock spring 26150 is mounted in the elongate channel 26310 and is configured to bias the firing member 26142 locking downward so that if a new unfired staple cartridge is not properly loaded into the elongate channel 26310, a distal edge 26149 of the locking body 26144 engages an angled distal edge 26317 26315 trigger lock hole. When in this position, if the user inadvertently attempts to advance the 26120 trigger member distally, locking the trigger member 26142 prevents distal advancement of the trigger member 26120 as shown in Figure 86.

[0350] A new, unfired surgical staple cartridge contains a 26650 cam assembly that is situated in an unfired home position that is proximal to the rows of staple drivers that are supported on the cartridge body. As used in the present invention, the terms "new, unfired" means that the staple cartridge has all of its intended staples or fasteners in their respective unfired positions and the cam assembly is in a proximal, initial, unfired position. When a fresh, unfired surgical staple cartridge has been properly seated within the elongated channel 26310, a proximally extending unlocked portion 26653 on cam assembly 26650 engages slider lock 26148 over firing member lock 26142 to pivot the trigger member lock 26142 to an unlocked position in which the trigger member lock 26142 does not extend into the trigger lock hole 26315 in the elongate channel 26310. Figure 85 illustrates a cam assembly 26650 in position and the 26120 triggering member is free to be advanced distally by actuation of the triggering trigger system.

[0351] Upon completion of the firing process, Cam Assembly 26650 may remain at the distal end of the staple cartridge (i.e. in a "fire" position) while firing member 26120 is retracted back to its home position in which the anvil can be opened and the spent cartridge removed from channel 26310. In this way, after a surgical staple cartridge has been spent (eg, fully fired), the cam assembly 26650 is not returned to its home position. As such, if the spent cartridge is inadvertently reinstalled in the 26300 end actuator, the 26650 cam assembly will not be in a home position where the 26650 cam assembly can unlock the 26142 firing member lock. 26140 firing member locking may also be referred to in the present invention as a "spent cartridge locking system".

[0352] Figures 87 to 90 illustrate an anvil 26400 that is configured to be pivotally supported over channel 26310 or a similar channel of the various types disclosed herein. In Figures 87 to 89, the channel has been omitted for clarity. In the illustrated arrangement, the anvil 26400 includes a cartridge verification system 26440 that can be configured to prevent firing of an otherwise incompatible cartridge seated in the cartridge channel. The 26400 Anvil and 26440 Anvil Verification System can be used in conjunction with a 26300 Surgical End Actuator that uses a 26120 Trigger Member that is equipped with a 26140 Internal Trigger Member Locking System that is configured to prevent the Distal advancement of trigger member 26120 unless triggering member lock 26142 has been moved to an unlocked position through interaction with a corresponding cam assembly located on the surgical staple cartridge. The 26440 Cartridge Verification System can also be used in connection with surgical end actuators that use an axially advanced (non-rotating) trigger member that is otherwise equipped with a trigger member locking system that is similar to to the 26140 firing member locking system.

[0353] Figure 90 illustrates a portion of a 26600 surgical staple cartridge that is compatible with the surgical end actuator

26300. In at least one arrangement, the surgical staple cartridge 26600 comprises an elongate cartridge body 26602 that is sized to be removably seated in the elongate channel of the end actuator 26300. The cartridge body 26602 includes a cartridge slot 26608 which extends from a proximal end portion 26604 to a distal end portion of cartridge body 26602. Cartridge body 26602 further comprises a cartridge platform surface 26610 which confronts a lower surface of cartridge 26602. clamping 26404 of the anvil 26400 is formed when the cartridge 26600 is seated in the channel and the anvil 26400 is pivoted to a closed position. Although not shown in Figure 90, the surgical staple cartridge 26600 may have a plurality of (generally three) rows of surgical staple pockets on each side of the cartridge slot 26608 that open through the cartridge platform surface 26610. Each staple pocket may have a staple driver (not shown) associated therewith that supports a surgical staple or fastener (not shown) thereon. In at least one example, the 26602 cartridge body is molded from a polymeric material with the staple pockets molded or machined therein. In one arrangement, the staple pockets also open through a bottom of the 26602 cartridge body to facilitate installation of the triggers and fasteners into their respective pockets. After the drivers and fasteners are inserted into their respective staple pockets, a 26620 cartridge tray is attached to the bottom of the 26602 cartridge body. When installed, the 26620 cartridge tray can, among other things, prevent the drivers from being screws and fasteners fall out of the bottom of the 26602 cartridge body when handling and installing the 26600 cartridge in the elongated channel

26310.

[0354] In the illustrated arrangement, the cartridge 26600 operatively supports a cam assembly 26650 therein. Cam assembly 26650 comprises a central body portion 26652 and a series of spaced-apart cam members 26654 that are configured to move axially within corresponding cam slots 26609 formed on either side of cartridge slot 26608 in the body. cartridge

26602. Cam slots 26609 are aligned with corresponding rows of drivers on cartridge body 26602 to facilitate cam contact with a corresponding cam member 26654 as the 26650 cam assembly is driven through the cartridge of clips 26600 from a starting position within the proximal end portion 26604 of the cartridge body 26602 to an ending position within the distal end portion 26602. The central body portion 26652 includes the unlocking portion that extends proximally. - mind 26653 which is configured to engage the slider lock 26148 into the firing member lock 26142 when the 26600 cartridge has been properly loaded into the 26310 channel. As can be seen in Figure 90, when the 26650 cam assembly is in its home position most proximal to which the unlocked portion 26653 can move the triggering member lock 26142 to the unlocked position, each of the cam members 26654 can protrude. air proximally out of their respective cam slots 26609.

[0355] Now with reference to Figures 87 and 91, in the illustrative arrangement

26440 cartridge verification system comprises a verification member or shuttle member 26442 that is attached to a lower side of an anvil mounting portion 26410 of the anvil.

26400. Cartridge check member 26442 may be a one-piece construction and include a pair of downwardly extending shuttle legs 26444 that are bifurcated by a firing member slot 26447 (Figure 91) to facilitating the passage of the firing member 26120 therebetween. In other arrangements, the cartridge check member 26442 may be a two-piece construction consisting of two separate downwardly extending shuttle legs 26444 that are separated from each other by a space 26448 that is configured to accommodate the passage of the firing member body 26122 therethrough. In either case, the shuttle member 26442 may be made of a malleable rubber or polymeric material and be secured to the underside of the anvil mounting portion 26410 by suitable adhesive of fastener arrangements.

[0356] In the illustrated example, each leg of the 26444 shuttle includes a slider actuator arm that projects distally

26446. Returning to Figure 90, the 26602 cartridge body includes two verification features or key portions of the cartridge that protrude proximally to the 26630 that are configured to unlockly engage the slider actuator arm 26446 on one leg. 26444 matching shuttle when the 26600 cartridge is operationally seated in the 26310 channel. As will be discussed further below, if the 26630 verification features are not present to contact the actuator arm of the corresponding 26446 slider, the actuator arm of slider 26446 could otherwise contact the cam members in projection 26654 and push or push the cam assembly

26650 distally to a position where the unlocking portion 26653 on the cam assembly 26650 is no longer in unlocking engagement with the slider lock 26148 on the triggering member lock 26142.

[0357] The interaction between the 26440 Cartridge Verification System and the 26600 Cartridge can be understood with reference to Figures 87 to

92. Figure 87 illustrates the initial installation of a compatible 26600 Surgical Staple Cartridge into the 26300 End Actuator. Although the channel is omitted from the drawings, the 26400 anvil is shown in a fully open position. In the illustrated example, the anvil 26400 is movably seated on the channel so that upon application of an initial closing movement thereto from a closing member arrangement of many of the various closing systems described herein, the 26400 anvil pivots to a partially closed or intermediate position shown in Figure 88. When in this position, each 26446 slider actuator arm is aligned confrontationally with the corresponding check feature 26630 on the 26602 cartridge body. The application Additional closing movement to the anvil 26400 may also cause the anvil 26400 to translate distally to a closed position. When the 26400 anvil moves distally, the 26630 verification features block distal movement of the corresponding 26446 flexible slider actuator arms to prevent the 26446 slider actuator arm from contacting the protruding cam members. proximally 26654. In this way, the cam assembly 26650 remains in its initial position in which the unlocking portion 26653 on the unlocking cam assembly 26650 remains in unlocking engagement with the slider lock 26148 on the triggering member.

26142. In this way, the trigger member 26120 is free to move distally through the cartridge 26600 upon actuation of the trigger system.

[0358] Figure 92 illustrates a 26600X cartridge that may be very similar to the 26600 cartridge but is "incompatible" with the 26300 surgical end actuator. For example, the 26600X cartridge does not have the 26630 verification features or key portions. from the 26600 cartridge. In addition to not having the 26630 verification features or keys, the 26600X cartridge may also differ from the 26600 cartridge in numbers, sizes, locations, and so on. of the fasteners contained therein, however the 26600X cartridge may have a 26650 cam assembly that is identical in construction and use to the 26650 cam assembly used in the 26600 cartridges.

[0359] Figures 93 through 95 illustrate the insertion of a 26600X incompatible staple cartridge into the 26300 Surgical End Actuator. Figure 93 illustrates the initial installation of a 26600X Incompatible Surgical Staple Cartridge into the 26300 End Actuator. channel has been omitted from the drawings, anvil 26400 is shown in a fully open position. Figure 94 illustrates the 26400 anvil in an intermediate position by applying an initial closing motion to it. When in that position, each slider actuator arm 26446 is confrontationally aligned with corresponding cam members 26654 that protrude proximally out of their respective cam slots 26609. The additional application of closing motion to the anvil 26400 can cause the anvil 26400 to translate distally to a final closed position. As the anvil 26400 moves distally, the arms of the slider actuator 26446 contact the proximally projecting cam members 26654 and move the cam assembly 26650 distally to a point where the unlocking portion 26653 over the it is no longer in engagement with the 26148 slider lock on the 26142 trigger member lock. In this way, the 26142 trigger member lock remains in locking engagement with the 26310 elongated channel of the 26300 end actuator to prevent Distal advancement of the 26120 triggering member through actuation of the triggering trigger system.

[0360] Figures 96 to 98 illustrate another 26440' cartridge verification system that can be used with a 26300' end actuator that uses a 20500 trigger member that is axially advanced by a 1900 trigger member beam. in the various ways discussed in the present invention. As discussed above, firing member 20500 comprises a firing member body 20502 which is configured to pass through vertically axially aligned slots in the anvil (not shown), a staple cartridge 26600', and elongated channel 26310 '. A lower foot assembly 20506 comprising a pair of laterally extending lower flanges extends from a lower end of the firing member body 20502 to slidably engage corresponding channel protrusions which are formed on either side of the slot. of channel. An upper foot comprising two laterally extending anvil lugs 20507 can be formed at an upper end of the firing member body 20502 and is configured to slidably engage the anvil projections (not shown) that are formed on each side of the anvil slot. In at least one arrangement, the firing member 20500 additionally includes a pair of central flaps (not shown) that extend laterally on either side of the firing member body 20502.

[0361] The trigger member body 20502 is also configured with a proximally extending spring tail 20512 that may be configured to interface operatively with a trigger member locking spring (not shown) that mounts to the elongated channel 26310 and is configured to bias the trigger member

20500 down in the elongated channel 26310 to a locked position.

When in the locked position, the foot of the triggering member 20506 and/or the central tabs are misaligned with corresponding passages in the channel 20310 and as such, should the user attempt to advance the triggering member 20500 distally when in that locked state, the triggering member 20500 will not move distally due to such misalignments.

That is, the foot 20506 and/or the central tabs contact portions of the elongated channel 20310' to thereby prevent distal advancement of the firing member 20500. In one arrangement, a slider lock 20514 is formed on the body. of firing member 20502 and is configured to be engaged by a proximally extending unlocking portion 26653' over a cam assembly 26650' that is operatively supported in a more proximal home or unfired position of a compatible cartridge 26600 ' which was operationally seated on channel 26310'. When a new, unfired staple cartridge 26600' with its cam assembly 26650' in its unfired position has been operatively installed in the elongated channel 26310', the unlocking portion 26653' on the cam assembly 26650' engages the latch. of the slider 20514 in the trigger member body 20502 and moves the trigger member 20500 up to an unlocked position in which the lower foot assembly 20506 and/or the center tabs are aligned with the respective passages in the channel 26310 ' to allow the firing member 20500 to advance axially therein.

As the user distally advances the trigger member 20500 on the 26600' cartridge, the trigger member 20500 also drives the cam assembly 20650' thereon which provides cam movement to the drivers upwards to drive the clamps or fasteners supported on the cartridge. even in formation contact with the underside of the anvil.

The fabric cutting member 20504 in the triggering member 20500 then cuts through the stapled fabric.

After the trigger member 20500 has been driven to its most distal position which corresponds to the end position of the cam assembly 26650', the trigger member 20500 is retracted back to its most proximal position, leaving the cam assembly 26650' at the distal end of the 26600' cartridge. When the trigger member 20500 returns to its most proximal starting position, the locking spring once again biases the trigger member 20500 back to its locked position. That way, if the user inadvertently tries to reuse the spent cartridge, the cam assembly 26650' is not in its home position which is needed to unlock the firing member 20500. Therefore, this locking arrangement of the firing member 20500 is firing may also be referred to in the present invention as "spent cartridge locking arrangement".

[0362] In the arrangement shown in Figures 96 and 97, the cartridge verification system 26440' comprises a cartridge verification member or seating shuttle 26442' which is supported within the channel 26310' for axial movement from a more distal cartridge engagement position to a proximal checkpoint within the 26310'. A shuttle spring 26449' is mounted within the channel 26310' and serves to bias the cartridge check member or seating shuttle 26442' to the most distal position of cartridge engagement. As can be seen in Figures 96 and 97, the cartridge check shuttle member or shuttle 26442 additionally includes a pair of slider actuator arms 26446' that project distally. The actuator arms of the 26446' slider are positioned to contact corresponding cam members on a cam assembly of a non-malleable cartridge as discussed below.

[0363] Figure 98 illustrates a proximal end portion 26604' of the surgical staple cartridge 26600' that is compatible with the surgical end actuator 26300'. In at least one arrangement, the surgical staple cartridge 26600' comprises an elongate cartridge body 26602' which is sized to be removably seated in the elongate channel 26310'. Cartridge body 26602' includes a cartridge slot 26608' extending from a proximal end portion 26604' to a distal end portion of cartridge body 26602'. Cartridge body 26602' further comprises a cartridge platform surface 26610' which faces a lower staple forming surface of the anvil when cartridge 26600' is seated in channel 26310' and the anvil is pivoted into a position closed. Although not shown in Figure 98, the surgical staple cartridge 26600' may have a plurality of (generally three) rows of surgical staple pockets on each side of the cartridge slot 26608' that open through the cartridge platform surface. 26610'. Each staple pocket may have a staple driver (not shown) associated therewith that supports a surgical staple or fastener (not shown) thereon. In at least one example, the cartridge body 26602' is molded from a polymeric material with the staple pockets molded or machined therein. In one arrangement, the staple pockets also open through a bottom of the 26602' cartridge body to facilitate installation of the triggers and fasteners into their respective pockets. After the drivers and fasteners are inserted into their respective staple pockets, a 26620' cartridge tray is attached to the bottom of the 26602' cartridge body. When installed, cartridge tray 26620' can, among other things, prevent drivers and fasteners from falling out of the bottom of cartridge body 26602' during handling and installation of cartridge 26600' into elongated channel 26310'.

[0364] In the illustrated arrangement, the cartridge 26600' operatively supports a cam assembly 26650' therein. Cam assembly 26650' comprises a central body portion 26652' and a series of spaced-apart cam members 26654' which are configured to move axially within corresponding cam slots 26609' formed on either side of cartridge slot 26608 ' in cartridge body 26602'. Cam slots 26609' are aligned with corresponding rows of drivers on cartridge body 26602' to facilitate cam contact with a corresponding cam member 26654' as cam assembly 26650' is driven through the cartridge of clips 26600' from a starting position within the proximal end portion 26604' of the cartridge body 26602' to an ending position within the distal end portion 26602'. The central body portion 26652' includes the proximally extending unlocking portion 26653' which is configured to engage the slider lock 20514 on the firing member 20500 when the cartridge 26600' has been properly loaded into the channel 26310'.

[0365] Compatible 26600' cartridge additionally includes verification features or key formations that protrude proximally 26630' that are configured to engage slide actuator arms 26446' when cartridge 26600' is operationally seated in channel 26310' . In the illustrated arrangement, the additional 26602' cartridge body has bilateral verification features or 26632' cartridge key formations that are also configured to engage the 26442' cartridge verification shuttle member or shuttle. As will be discussed further below, if the check formations 26630', 26632' are not present to contact the corresponding slider actuator arm 26446' and the check cartridge shuttle member 26442', the actuator arms of slider 26446' could otherwise contact protruding cam members 26654' and push or urge cam assembly 26650 distally to a position where unlocking portion 26653' on cam assembly 26650' is no longer in unlocking engagement with slider lock 20514 on trigger member 20500.

[0366] Referring now to Figures 99 to 101, in the arrangement shown, the verification features or key formations 26630', 26632' each have an angled bottom alignment surface 26634' thereon that facilitate initial insertion of cartridge 26600' into channel 26310' in a first position angle (FPA) in which angled bottom alignment surfaces 26634' prevent contiguous contact with slider actuator arms 26446 '. Surfaces 26634' may be called secondary surfaces in the present invention. After the user has positioned the surgical staple cartridge 26600' in the first installation position, the cartridge 26600' is then pivoted down into channel 26310' at position 2 at which the vertical contiguous surfaces 26636' (surfaces secondary) on the check features or cartridge key formations 26630', 26632' are in a boundary position with the corresponding vertical contiguity surfaces 26641' and 26647' (primary surfaces) on the check member or shuttle of the 26442 cartridge '. The user can then advance the cartridge 26600' proximally to position 3 within the elongated channel 26310'.

[0367] Figure 102 illustrates the insertion of an incompatible 26600X' surgical staple cartridge into the 26300' surgical end actuator. In this example, the 26600X’ incompatible cartridge does not have the verification capabilities or the 26630’, 26632’ cartridge key formations that were provided on the 26600’ compatible cartridge to engage the 26442’ cartridge verification shuttle member or shuttle. In this way, as the 26600X' cartridge is seated in the 26310' channel, the actuator arms of the 26446' slider contact the projecting cam members 26654' and push or push the distal 26650' cam assembly. - set to a position in which the unlocking portion 26653' on the cam assembly 26650' is not in unlocking engagement with the slider lock 20514 on the triggering member 20500. In this way, the triggering member 20500 remains locked in position and the user would be unable to advance the 20500 firing member distally into the 26600X' incompatible cartridge.

[0368] Figures 103 and 104 illustrate the insertion of the incompatible 26600X' cartridge into the 26300' end actuator, with the incompatible 26600X' cartridge being initially inserted too long proximally in the 26310' channel, so that the distal end of the firing member 20500 has contacted and pushed the cam assembly 26650' or "slider" too far distally within the 26600X' cartridge so that it is in the proper position to latch unlockably engage the slider latch portion 20514 of the 26600X' cartridge. firing member 20500 after the 26600X' has finally been seated in the channel 26310' in a suitable position. Likewise, when the incompatible cartridge 26600X' is initially inserted in a diagonal positioning 1 as described above, and then moved to positions 2 and 3, the firing member 20500 can push the cam assembly 26650 ' or slide it distally out of the trigger member unlock position so that when properly seated, the 26650' cam assembly would not be sufficient to unlock the 20500 trigger member. See Figures 105 and 106.

[0369] Figures 107 to 109 illustrate another 26440'' cartridge verification system that can be used with a 26300'' end actuator that uses a 20500 trigger member that is axially advanced by a 1900 trigger member beam in the various ways discussed in the present invention. As discussed above, the trigger member 20500 comprises a trigger member body 20502 that is configured to pass through vertically axially aligned slots in the anvil (not shown), a staple cartridge, and the elongated channel 26310 ''. A lower foot assembly (not shown) comprising a pair of laterally extending lower flanges extends from a lower end of the firing member body 20502 to slidably engage corresponding channel protrusions that are formed in each side of the channel slit. An upper foot 20507 comprising two laterally extending anvil lugs 20509 may be formed at an upper end of the firing member body 20502 and is configured to slidably engage the anvil projections (not shown) which are formed on each side of the anvil slit. In at least one arrangement, the firing member 20500 additionally includes a pair of central flaps 20510 that extend laterally on either side of the firing member body 20502.

[0370] The 20502 trigger member body is also configured with a proximally extending spring tail (not shown) that can be configured to interface operationally with a trigger member locking spring (not shown) that is mounted in the elongated channel 26310'' and is configured to bias the firing member 20500 downward in the elongated channel 26310' to a locked position. When in the locked position, the foot of the trigger member 20510 and/or the central tabs 20510 are misaligned with corresponding passages in the channel 20310 and as such, should the user attempt to advance the trigger member 20500 distally when in that locked state, the trigger member 20500 will not move distally due to such misalignments. That is, the foot and/or central tabs 20510 contact portions of the elongated channel 26310" to thereby prevent distal advancement of the trigger member 20500. In one arrangement, a slider lock 20514 is formed in the body. of firing member 20502 and is configured to be engaged by an unlocking portion that extends proximally over a cam assembly that is operatively supported in an initial or unfired position more proximally on a compatible cartridge that has been operationally seated in channel 26310''.

[0371] When a new, unfired staple cartridge with its cam assembly in its home (unfired) position has been operatively installed in the elongated channel 26310'', the unlocking portion on the cam assembly engages the slider 20514 locks onto trigger member body 20502 and moves trigger member 20500 upward to an unlocked position in which the lower foot assembly and/or center tabs 20510 are aligned with respective passages in channel 26310' ' to allow the firing member 20500 to advance axially therein. As the user distally advances the firing member 20500 into the cartridge, the firing member 20500 also drives the cam assembly thereon which provides cam movement to the drivers upward to drive the clamps or fasteners supported on the cartridge. even in formation contact with the underside of the anvil. A fabric cutting member 20504 on firing member 20500 then cuts through the stapled fabric. After the trigger member 20500 has been driven to its most distal position which corresponds to the final position of the cam assembly, the trigger member 20500 is retracted back to its most proximal position, leaving the cam assembly at the distal end (fired position ) of the cartridge. As the trigger member 20500 returns to its most proximal starting position, the locking spring once again biases the trigger member 20500 back to its locked position. That way, in case the user inadvertently tries to reuse the spent cartridge, the cam assembly is not in its initial position which is necessary to unlock the firing member 20500. Such firing member locking system can also be called in the present invention as "spent cartridge locking system".

[0372] In the arrangement shown in Figures 107 to 109, the cartridge checking system 26440'' comprises an axially movable cartridge checking shuttle 26442'' which is supported within the channel 26310'' for axial movement to from a more distal cartridge engagement position to a proximal check location within the 26310''. A shuttle spring 26449'' is mounted within the channel 26310'' and serves to bias the cartridge check shuttle 26442'' to the most distal position of cartridge engagement. As can be seen in Figures 107 and 108, the check cartridge shuttle 26442'' additionally includes distally extending shuttle base members 26644'' and a pair of laterally movable shuttle drive arms. 26450''. Each shuttle drive arm 26450'' has a drive lock feature 26452'' on it which has an angled proximal drive surface 26454'' and an angled distal drive surface 26456'' that converge together to form a point. 26548''. The 26450'' shuttle drive arms are biased laterally inward to a spring actuated position by the 26449'' shuttle spring. When the shuttle drive arms 26450'' are in the drive position, the angled proximal drive surfaces 26454'' are in drive engagement with the center tabs 20510 on the firing member 20500 as shown in Figures 107 and 108 When the 26450'' shuttle drive arms are in this position, the distal advance of the 20500 triggering member will cause the 26442'' seating shuttle to move distally with it.

[0373] Figure 109 illustrates a proximal end portion 26604'' of the surgical staple cartridge 26600'' that is compatible with the surgical end actuator 26300'' seated with channel 26310". In at least one arrangement, the surgical staple cartridge 26600'' comprises an elongate cartridge body 26602'' that is sized to be removably seated in the elongated channel 26310'. Cartridge body 26602'' includes a cartridge slot 26608'' extending from proximal end portion 26604'' to a distal end portion of cartridge body 26602''. The cartridge 26600'' operatively holds a cam assembly 26650'' therein. Cam assembly 26650'' comprises a central body portion 26652'' and a series of spaced-apart cam members 26654'' which are configured to move axially in corresponding cam slots 26609'' formed on either side of the slot. cartridge 26608'' in cartridge body 26602''. Cam slots 26609'' are aligned with corresponding rows of drivers on cartridge body 26602'' to facilitate cam contact with a corresponding cam member 26654'' as cam assembly 26650'' is driven through the staple cartridge 26600'' from a starting position within the proximal end portion 26604'' of the cartridge body 26602'' to an ending position within the distal end portion 26602''. Central body portion 26652'' includes proximally extending unlocking portion 26653'' which is configured to engage slider lock 20514 on firing member 20500 when cartridge 26600'' is properly loaded into channel 26310' '.

[0374] The compatible 26600'' cartridge additionally includes proximally protruding unlocking features or 26630'' cartridge key formations that are configured to engage the 26450'' shuttle drive arms when the 26600'' cartridge is operationally seated on channel 26310''. As can be seen in Figure 109, during distal advancement of the 20500 triggering member, the 26442'' check shuttle is driven distally until each 26450'' shuttle drive arm comes into contact with a formation of matching cartridge key 26630'' which causes the shuttle drive arms 26450'' to tilt out laterally. As the trigger member 20500 continues to move distally, the trigger lock features 26452'' on the shuttle trigger arms 26450'' disengage from the corresponding center tabs 20510 on the trigger member body 20502 to allow the trigger member 20502 to trigger 20500 to move distally without triggering check shuttle 26442'' distally. Therefore, in such a case, the check shuttle 26442'' has not moved distally enough to move the cam assembly 26650” out of the latch in an unlocked manner with the slider lock 20514 on the firing member. 20500. Therefore, the 20500 trigger member can be driven distally through the 26600” compatible cartridge to drive fasteners therefrom and to cut tissue that has been clamped on the 26300” end actuator. When the trigger member 20500 is retracted back to its home position, a tapered surface 20511 on each center tab 20510 contacts the angled distal drive surface 26456” on the corresponding trigger lock feature 26452” to bias the 26452” obturator arms 26450” laterally to allow central tabs 20510 to re-engage angled proximal driving surfaces 26454” so that check plug 26442'' can once again be driven distally with triggering member 20500.

[0375] Figures 107 and 108 illustrate an incompatible cartridge 26600X'' loaded in the surgical end actuator 26300''. As can be seen from these figures, the 26600X'' incompatible cartridge does not have the proximally protruding unlocking features or 26630'' cartridge key formations that are provided in the 26600'' compatible cartridge. In this way, when the firing member 20500 is advanced distally, the check cartridge shuttle 26442'' also moves distally with the firing member 20500.

As cartridge check shuttle 26442'' moves distally, the distal ends 26645'' of the distally extending check shuttle base members 26644'' contact cam assembly 26650'' and move cam assembly 26650” out of the unlocking engagement with slider lock 20514 on trigger member 20500. When unlocking portion 26653'' of cam assembly 26650'' disengages slider lock 20514, the body of the member trigger 20502 will fall into locking engagement with elongated channel 26310'' thus preventing further distal advancement of trigger member 20500.

[0376] As can be further seen in Figures 108 and 109, in the illustrated arrangement, a side stiffening member 26470'' projects laterally outward from each shuttle arm 26450''. When firing member 20500 and check shuttle 26442'' are located in their respective most proximal starting positions, each side stiffening member 26470'' is laterally aligned with a corresponding channel notch 26472'' provided in each wall. 26314'' channel side to provide clearance for the 26450'' shuttle arms to move laterally when a 26600'' compatible cartridge has been properly loaded into the 26300'' end actuator. However, when an incompatible 26600X'' cartridge has been loaded into the 26300'' end actuator and the user begins to advance the 20500 firing member as well as the 26442'' check shuttle distally, the 26470'' side stiffening members are no longer aligned with the notches of channel 26472'' in the side walls of channel 26314'' as can be seen in Figure 108. In such an example, side stiffening members 26470'' prevent shuttle arms 26450'' from protruding laterally outwardly. with central tabs 20510 extending laterally from each side of the firing member body 20502.

[0377] The cartridge check systems described here can solve several problems that may, from time to time, be encountered when using an end actuator that is capable of initially accepting a variety of cartridges, some of the cartridges being are otherwise not particularly compatible with the end actuator.

For example, a cartridge may operatively fit inside the end actuator channel, but the cartridge may not have proper closure configurations that are compatible with the forming pockets on the end actuator anvil.

The incompatible cartridge may not have the proper numbers and shapes of staples, etc.

The cartridge may not have a cam assembly that is compatible with the firing member locking arrangement used by the end actuator.

Some cartridges may have a suitable cam assembly, but the cam assembly may at some point have moved to a marginal unlocked position at which the cam assembly may or may not unlockly engage the firing member's locking arrangement. .

At least some of the cartridge verification systems can resolve this issue.

The cartridge verification systems disclosed herein may also provide the ability to differentiate between an old, obsolete cartridge and a newer, more suitable cartridge, for example, which has, for example, features that are better matched to the components of the end actuator.

Cartridge verification systems can also ensure that a cartridge is properly seated in the end actuator channel and minimize any misalignment of the cartridge in the channel, with the proximal end of the cartridge positioned relative to the firing member in an undesirable position in which the center tabs on the firing member may be under the cartridge tray rather than on top of it, as desired.

Such misalignment can result in damage and bending of the cartridge tray which could lead to premature locking of the firing member.

[0378] Figures 110 through 115 illustrate another 27440 cartridge verification system that can be used with a 27300 end actuator that uses a 20500 trigger member (described above) that is axially advanced by a trigger member 1900 in the various ways discussed in the present invention. In the illustrated arrangement, the cartridge verification system 27440 comprises an axially movable cartridge verification shuttle member or shuttle 27442 which is supported within the channel 27310 of the end actuator 27300 for axial movement from a more distal position of engagement. cartridge to a proximal check location within channel 27310. Cartridge check member or shuttle 27442 may be manufactured from spring steel and include an elongate body 27444 that has a locking hook 27446 that is formed at one end Distal 27445 of Elongated Body 27444. See Figure

111. Cartridge check member or shuttle 27442 additionally includes an actuator portion 27448 that is formed at a proximal end 27447 of the elongate body 27444.

[0379] Still referring to Figure 111, the check member or shuttle of the cartridge 27442 is configured to move axially within a shuttle rail 27360 which is formed in a bottom of channel 27312 of channel 27310. Seen in Figure 111, the rail shuttle 27360 comprises a transverse curved portion 27362 that extends transversely with respect to a channel slot 27313 that is centrally disposed in the lower channel 27312 to accommodate the axial passage of the firing member 20500 therethrough. The transverse curved portion 27362 of the shuttle rail 27360 terminates in an inclined rail portion 27364 which is situated on the other side of the channel slot 27313. As can be seen in Figure 111, the inclined rail portion 27364 has a surface 27366. A proximal end 27370 of the shuttle rail 27360 adjoins an axial spring cavity 27380 which is configured to support a shuttle spring 27382 which is seated in a projecting spring retainer pin 27449 proximally from the actuator portion 27448 of the 27442 Checking Shuttle Member or Cartridge 27382. The 27382 Check Shuttle Spring serves to bias the 27442 Check Shuttle to a more distal locked position, with the 27442 Checking Shuttle Member or Cartridge Locking the distal advance of a cam assembly 27650 and trigger member 20500.

[0380] Figure 110 illustrates a proximal end portion 27604 of the surgical staple cartridge 27600 that is compatible with the surgical end actuator 27300. In at least one arrangement, the surgical staple cartridge 27600 comprises an elongated cartridge body 27602 that is sized to be removably seated in elongate channel 27310. Cartridge body 27602 includes a cartridge slot 27608 that extends from proximal end portion 27604 to a distal end portion of cartridge body 27602 Cartridge body 27602 further comprises a cartridge platform surface 27610 which faces a lower staple forming surface of the anvil when cartridge 27600 is seated in channel 27310 and the anvil is pivoted to a closed position. Although not shown in Figure 110, the 27600 surgical staple cartridge may have a plurality of (generally three) rows of surgical staple pockets on each side of the 27608 cartridge slot that open through the cartridge platform surface. 27610. Each staple pocket may have a staple driver (not shown) associated with it that supports a surgical staple or fastener (not shown) over it. In at least one example, the cartridge body

27602 is molded from a polymeric material with the staple pockets molded or machined into it. In one arrangement, the staple pockets also open through a bottom of the 27602 cartridge body to facilitate installation of the triggers and fasteners into their respective pockets. After the drivers and fasteners are inserted into their respective staple pockets, a 27620 cartridge tray is attached to the bottom of the 27602 cartridge body. When installed, the 27620 cartridge tray can, among other things, prevent the drivers from screws and fasteners fall out of the bottom of the 27602 cartridge body when handling and installing the 27600 cartridge in the elongated channel

27310

[0381] In the illustrated arrangement, the cartridge 27600 operationally supports a cam assembly 27650 therein. Cam assembly 27650 comprises a central body portion 27652 and a series of spaced cam members 27654 which are configured to move axially within corresponding cam slots 27609 formed on either side of cartridge slot 27608 in the cartridge body 27602. Cam slots 27609 are aligned with corresponding rows of drivers on cartridge body 27602 to facilitate cam contact with a corresponding cam member 27654 as the cam assembly 27650 is driven through the cartridge of staples 27600 from a starting position within the proximal end portion 27604 of the cartridge body 27602 to an ending position within the distal end portion

27602. The central body portion 27652 includes the proximally extending unlocking portion 27653 that is configured to engage the slider lock 20514 on the firing member 20500 when the cartridge 27600 is properly loaded into the channel.

27310

[0382] The 27600 compatible cartridge additionally includes a proximally protruding verification feature or 27630 cartridge key formation that is configured to engage the 27448 slider actuator when the 27600 cartridge is operationally seated in the 27310 channel. 27630 check feature biases the 27442 cartridge check member or shuttle to the most proximal unlocked position where the 27650 cam assembly and 20500 trigger member can be moved distally through the 27600 cartridge. Check cartridge 27442 limb or check shuttle is in the unlocked position, the locking hook 27446 that is formed at the distal end 27445 of the elongate body 27444 of the 27442 check cartridge shuttle member or shuttle is retracted into the transverse curved portion 27362 of the check rail. shuttle 27360 and does not extend through channel slot 27313 at the bottom of channel 27312. When locking hook 27446 does not extend through channel slot 27313, firing member 20500 and cam assembly 27650 can be advanced into cartridge 27310''.

[0383] Figures 114 and 115 illustrate the 27300 surgical end actuator with an incompatible 27600X cartridge installed in it. In this example, the 27600X incompatible cartridge does not have the 27630 cartridge check or key formation feature that was provided in the 27600 compatible cartridge to engage the 27448 actuator portion of the 27442 check cartridge shuttle or member. , the shuttle spring 27382 has biased the cartridge check shuttle member or shuttle 27442 distally to its closed position in which the locking hook 27446 which is formed at the distal end 27445 of the elongated body 27444 of the member or shuttle check cartridge 27442 extends transversely along channel slot 27313 and into slanted track portion 27364. As locking hook 27446 enters slanted track portion 27364, angled bottom surface 27366 causes the hook 27446 moves up to a position where the 27446 locking hook blocks the distal advancement of the 27650 cam assembly and the 20500 triggering member. Accordingly, when in that position, if the user inadvertently attempts to advance the 20500 triggering member distally, the 27446 locking hook will block the 27650 cam assembly and 20500 triggering member from distal advancement.

[0384] In at least one arrangement, as shown in Figure 115, the portion of the locking hook 27446 that extends transversely through the channel slot 27313 may be reinforced with an additional reinforcement block portion 27450 that is secured to the same. That is, the portion of the locking hook 27446 that is reinforced has a cross-sectional thickness that is greater than a cross-sectional thickness of the remaining body portions of the 26442 cartridge check member or shuttle. Alternative arrangements are contemplated for use with those end actuators disclosed in the present invention which use an axially movable closing member to move the anvil to a closed position, such as an end actuator closing tube. In such end actuator arrangements, for example, the closing tube of the end actuator can be configured to bias the check shuttle to the locked position, locked when the closing member is actuated to close the anvil. . The 27440 Cartridge Verification System can also be effectively used with surgical end actuators that have energized rotating firing member arrangements with firing member locking systems of the types disclosed herein.

[0385] Figures 116 to 119 illustrate a cartridge of citric staples.

28600 replacement parts that can be used in connection with the various end actuator arrangements disclosed in this document. In the illustrated arrangement, the surgical staple cartridge 28600 comprises an elongate cartridge body 28602 that is sized to be removably seated in the elongate channel of the end actuator. As can be seen in Figure 117, cartridge body 28602 includes a cartridge slot 28608 that extends from a proximal end portion 28604 of cartridge body 28602 to a distal end portion of the cartridge body.

28602. Cartridge body 28602 further comprises a cartridge platform surface 28610 which faces a lower clamping surface of the anvil when the cartridge 28600 is seated in the channel and the anvil is pivoted to a closed position. Although not shown in Figure 117, the surgical staple cartridge 28600 may have a plurality of (generally three) rows of surgical staple pockets on each side of the cartridge slot 28608 that open through the cartridge platform surface.

28610. Each staple pocket may have a staple driver (not shown) associated with it that supports a surgical staple or fastener (not shown) thereon. In at least one example, the cartridge body 28602 is molded from a polymeric material with the staple pockets molded or machined therein. In one arrangement, the staple pockets also open through a bottom of the 28602 cartridge body to facilitate installation of triggers and fasteners in their respective pockets. After the drivers and fasteners are inserted into their respective staple pockets, a 28620 cartridge tray is attached to the bottom of the 28602 cartridge body. When installed, the 28620 cartridge tray can, among other things, prevent drivers and fasteners fall out of the bottom of the 28602 cartridge body when handling and installing the 28600 cartridge in the elongated channel.

[0386] In the illustrated arrangement, the cartridge 28600 operatively supports a cam assembly 28650 thereon. Cam assembly 28650 comprises a central body portion 28652 and a series of spaced cam members 28654, 28654' which are configured to move axially within corresponding cam slots 28609 formed on each side of the cartridge slot. 28608 in cartridge body

28602. Cam slots 28609 are aligned with corresponding rows of drivers on cartridge body 28602 to facilitate cam contact with a corresponding cam member 28654, 28654' as the 28650 cam assembly is actuated through the staple cartridge 28600 from a starting position within the proximal end portion 28604 of the cartridge body 28602 to an ending position within the distal end portion 28602.

[0387] Still referring to Figure 117, the 28600 cartridge is equipped with a 28440 cam assembly locking system that is configured to retain the 28650 cam assembly in its starting position unless the 28600 cartridge does. has been loaded into a compatible end actuator. In the arrangement illustrated for example, the cam assembly locking system 28440 comprises a laterally displaceable locking feature 28442 comprising an actuator portion 28444 and a locking tab 28446. As can be seen in Figure 117, the locking tab 28446 The lock 28446 is configured to be received within a lock cavity 28655 provided in a corresponding cam member 28654' when the cam assembly 28650 is in a locked position. See Figures 116 and 117. The 28444 actuator portion is configured to be contacted by an actuator pin or other end actuator anvil portion when the anvil is moved to a closed position. For example, an actuator pin 28411 may be formed in an anvil mounting portion of any of the various anvils disclosed herein and be configured to laterally bias the actuator portion 28444 laterally into an unlocked position when the anvil is moved. to a closed position. When actuator portion 28444 is in an unlocked position, locking tab 28446 is moved laterally out of lock cavity 28655 on cam member 28654' and cam assembly 28650 can then be advanced distally through the 28600 cartridge when the trigger system is activated as described in the present invention. See Figures 118 and 119.

[0388] In various cases, a surgical stapling instrument comprises a cartridge grip configured to receive a replaceable staple cartridge. The stapling instrument further comprises a staple firing system configured to eject, or fire, staples from the staple cartridge and an anvil comprising forming surfaces, or pockets, configured to deform the staples. The staple firing system comprises a tissue cutting knife which is moved from a proximal end of the staple cartridge towards the distal end during a staple firing stroke. During the course of firing the staples, the fabric cutting knife abuts and pushes a slider on the staple cartridge that drives the staples towards and against the anvil. As the staples are deformed against the anvil, the staples are implanted into the fabric in longitudinal rows and the fabric cutting knife cuts the tissue between two of the longitudinal rows of staples. After the staple firing stroke has been completed, and/or after a sufficient length of the staple firing stroke has been completed, the tissue cutting knife is retracted proximally. However, the cartridge slider is not retracted proximally with the tissue cutting knife. Instead, the cartridge slider is left behind in the most distal position in which it was pushed by the tissue cutting knife. After a staple cartridge has fired, or at least partially fired, it is removed from the cartridge grip and then replaced with another replaceable staple cartridge, if desired. At this point, the stapling instrument can be reused to continue stapling and incising the patient's tissue. In some cases, however, a previously fired staple cartridge may accidentally be loaded into the cartridge's grip. If the tissue cutting knife is advanced distally into such a previously fired staple cartridge, the stapling instrument would cut the patient's tissue without stapling it. Similarly, the stapling instrument would cut the patient's tissue without stapling it if the tissue cutting knife were advanced distally through a staple firing stroke without a staple cartridge positioned in the cartridge grip. To this end, the stapling instrument comprises one or more interlocks that prevent this from happening, as discussed in more detail below.

[0390] Referring to Figure 120, a surgical stapling instrument 30000 comprises a cartridge gripper, or channel, 30010 and a staple cartridge 30020 seated in the cartridge gripper.

30010. The staple cartridge 30020 comprises a cartridge body 30022, staple cavities defined in the cartridge body 30022, and staples removably stored in the staple cavities. The staple cartridge 30020 further comprises a slider 30030 and staple drivers that are driven by the slider 30030 to eject the staples from the staple cavities as the slider 30030 is advanced distally during a staple firing stroke. The stapling instrument 30000 further comprises a triggering member 30040 which is configured to engage the slider 30030 and push the slider 30030 distally, as discussed in more detail below.

[0391] In addition to the above, the firing member 30040 comprises a cutting portion 30042 that includes a fabric knife

30044. Cutting portion 30042 further comprises a distal nose 30043 which is configured to rest on a shoulder 30033 defined on slider 30030 when slider 30030 is in its unfired position on staple cartridge 30020 and firing member 30040 is moved distally from its unfired position illustrated in Figure 120. When distal nose 30043 is on the shoulder of slider 30033, firing member 30040 can be advanced distally to execute a staple firing stroke. In particular, the cutting portion 30042 further comprises a first cam member 30046 configured to engage a cam surface of the channel 30010 and a second cam member 30048 configured to engage a cam surface on the anvil of the stapling instrument 30000 which cooperates to position the anvil and staple cartridge 30020 relative to each other. That said, embodiments without one or both cam members 30046 and 30048 are envisaged.

[0392] Referring to Figure 121, the trigger member 30040 is biased towards channel 30010 by a spring, and if the slider 30030 is not in its untriggered position when the trigger member 30040 is advanced distally to start the stroke trigger, the distal nose 30043 of the cutting portion 30042 will not contact, or would not come to rest on, shoulder 30033, and instead, the cutting portion 30042 will move down toward channel 30010. cutting portion 30042 comprises locking pins 30045 extending laterally therefrom which enter a locking window, or recess, 30012 defined in channel 30010 when distal nose 30043 does not land over shoulder 30033 of slider 30030. In such instances, triggering member 30040 is permitted to move distally within locking window 30012; however, the distal end of the locking window 30012 comprises a locking shoulder 30015 which is in contact with the locking pins 30045 to stop the distal advancement of the triggering member 30040. In such cases, as a result, the triggering member 30040 is locked and prevented from performing its staple firing stroke. If the slider 30030 were in its unfired position, however, the interaction between the distal nose 30043 of the cutting portion 30042 and the shoulder 30033 of the slider 30030 would prevent the triggering member 30040 from falling into the locking window 30012 and the firing stroke of staples could have been performed.

[0393] In addition to the above, the trigger member

30040 could fall into the 30012 locking window if the 30040 firing member was advanced distally without a staple cartridge positioned in and/or a staple cartridge properly seated in the 30010 cartridge channel. In view of the above, the surgical instrument 30000 comprises a lock that prevents the staple firing stroke if the staple cartridge in the surgical instrument 30000 is absent, improperly seated and/or has been at least partially worn. That said, several cases can arise when a staple cartridge has not been fired, i.e., all of its staples are still positioned in their staple cavities, and yet the distal nose 30043 of the cutting portion 30042 can not reach shoulder 30033 of slider 30030 due to, for example, various manufacturing tolerances. Such cases cause the firing member 30040 to lock unnecessarily and require a physician to replace the staple cartridge with another staple cartridge. Such cases may not happen often, but if they do, they are inconvenient for the doctor.

[0394] A surgical instrument 30100 is illustrated in Figure 122 and includes an enhancement that may reduce the possibility that the distal nose 30043 of the cutting portion 30042 does not reach the shoulder 30033 of the slider 30030. The surgical instrument 30100 is similar to the surgical instrument. The 30000 is logical in many respects but includes a staple cartridge 30120 instead of the staple cartridge 30020. The staple cartridge 30120 comprises a cartridge body 30122, staple cavities defined in the cartridge body 30122, and staples stored in a manner Removable in staple cavities. Referring to Figure 123, the staple cartridge 30120 additionally comprises a slider 30030 which, similarly to the above, is movable distally from a non-fired position during a staple firing stroke if the distal nose 30043 of the cutting portion 30042 strikes the shoulder 30033 of the slider 30030. Otherwise, with reference to Figure 124, the cutting portion 30042 is pushed into the locking window 30012 defined in the cartridge channel 30010 when the firing member 30040 is advanced distally.

[0395] Referring to Figures 125 and 126, cartridge body 30122 comprises proximal ramps 30126 configured to lift firing member 30040 upward when firing member 30040 is advanced distally. More specifically, locking pins 30045 extending laterally from firing member 30040 contact ramp surfaces 30127 defined in proximal ramps 30126 that guide cutting portion 30042 away from locking window 30012 when the 30040 triggering member is advanced distally. They do this, in addition to the above, against the biasing force of the spring pushing the firing member 30040 towards the cartridge channel 30010. Lifting the firing member 30040 thus increases the probability that the nose 30043 of the trigger member 30040 will land on the shoulder 30033 of the slider 30030 - even if the slider 30030 has been accidentally pushed slightly distally from its unfired position. In this way, the possibility of an unfired staple cartridge becoming unintentionally stuck is reduced. If the 30120 staple cartridge has been at least partially fired, however, the 30043 nose will not reach the 30033 shoulder and the 30045 locking pins will fall through a 30125 window defined between the 30126 proximal ramps and into the 30126 window. lock 30012. In this way, as described above, the surgical instrument 30100 will be locked out if an at least partially worn staple cartridge 30120 is seated in the cartridge channel 30010. Also, as described above, the surgical instrument 30100 will be locked out if a staple cartridge is missing from the 30010 cartridge channel and the staple firing stroke will start as the 30040 firing member immediately enters the 30012 locking window due to the absence of proximal ramps

30126.

[0396] In particular, in addition to the above, the ramps 30126 are positioned proximal to the shoulder 30033 of the slider 30030. As such, the firing member 30040 must consecutively pass the missing cartridge/cartridge lock. 30126 ramps and spent cartridge locking provided by the 30030 slider as the 30040 firing member is moved distally to execute the staple firing stroke. In addition, ramps 30126 raise firing member 30040 to a suitable height to be supported by slider 30030. Finally, ramps 30126 of cartridge body 30122 and shoulder 30033 of slider 30030 work together to overcome locks on the insulator. - 30100 stapling tool.

[0397] A staple cartridge 30220 is illustrated in Figure 127 according to at least one alternative embodiment. The 30220 staple cartridge comprises a 30222 cartridge body that is similar to the 30122 staple cartridge in many respects. That said, the cartridge body 30222 comprises proximal ramps 30226 that extend more proximally than the proximal ramps 30126. As such, the firing member 30040 will be raised earlier in its staple firing stroke when a staple cartridge 30220 is used. In various cases, the 30220 staple cartridge may include a larger dual window 30225 than the dual window 30125. In addition, the proximal ramps 30226 comprise ramp surfaces 30227 ramps that are shorter than the ramp surfaces 30127. In such cases , the 30040 triggering member will not be lifted as high when a 30220 staple cartridge is used compared to a 30120 staple cartridge. In either case, these parameters can be used to improve a proper lifting motion for the 30040 triggering member .

[0398] As discussed above, the locking pins 30045 of the triggering member 30040 are configured to contact the ramps 30226 that lift the triggering member 30040 so that the triggering member 30040 can land on the shoulder 30033 of the slider 30030 if the 30030 slider is properly positioned on the 30220 staple cartridge. That said, alternative arrangements are envisioned in which the ramps can lift any suitable portion of a staple firing member over the shoulder 30033 of the 30030 slider. For example, the firing member 30040 may comprise laminated bars attached to the cutting portion 30042 which contact the ramps 30226 and cause the firing member 30040 to be lifted upwards when the firing stroke of staples is initiated.

[0399] Again with reference to Figure 127, the staple cartridge 30220 comprises a tray 30024 that extends at least partially under the cartridge body 30222. Tray 30024 is configured to prevent staple drivers and/or staples within the cartridge body 30222 fall out of the bottom of cartridge body 30222. Tray 30024 comprises latches 30021 engaged with slots defined in cartridge body 30222. Tray 30024 additionally comprises windows 30029 defined therein which, in cooperation with the projections extending from the cartridge body 30222, align the tray 30024 with the cartridge body 30222. In addition to or in lieu of the above, lift ramps 30226, for example, may extend from the tray

30024

[0400] A 30300 surgical stapling instrument is illustrated in Figure 128. The 30300 stapling instrument is similar to the 30200 stapling instrument in many respects. That said, the 30300 stapling instrument comprises a 30320 staple cartridge instead of the 30220 staple cartridge. The 30320 staple cartridge comprises a cartridge body 30322, staple cavities defined in the cartridge body 30322, and staples stored in removable way in the clamp cavities. Cartridge body 30322 further comprises a longitudinal slot 30023 defined therein which is configured to receive firing member 30040 and, furthermore, a proximal ramp 30327 extending in front of longitudinal slot 30023 which lifts firing member 30040 over the 30030 slider if the 30030 slider is at, or at least close to, its unfired position, as illustrated in Figure 129. If the 30030 slider has been at least partially advanced through its staple firing stroke, the shoulder 30033 will not hit the nose 30043 of the firing member 30040 and the cutting portion 30042 will fall through a window defined between the ramp supports 30326 and into the locking window 30012.

[0401] Referring to Figures 130 and 132, ramp 30327 also comprises a door configured to pivot out of the way of the firing member 30040 path when sufficient pushing force is applied to firing member 30040. The ramp 30327 comprises a first end pivotally mounted to one of the ramp supports 30326 and a second end releasably secured to the other ramp support 30326. With reference to Figures 131 and 133, the second end of the ramp 30327 is configured to detach from its ramp support 30326 after the trigger member 30040 has been lifted up so that when the ramp 30327 gives way, the nose 30043 of the trigger member 30040 falls over the shoulder 30033 of the slider 30030 - if slider 30030 is in its non-fired position, or at least close to its non-fired position. At such a point, the ramp 30327 no longer impedes distal movement of the triggering member 30040 and the triggering member 30040 can be advanced distally through the longitudinal slot.

30023. Ramp 30327 remains offset to the side throughout the firing stroke of staples and after firing member 30040 has been retracted back to its unfired position. As such, the offset ramp 30327 cannot lift the trigger member 30040 should the trigger member 30040 need to be advanced distally once more. In such cases, the locking pins 30045 of the cutting portion 30042 would be pushed into the locking window 30012 by the spring acting against the triggering member 30040 if the triggering member 30040 is advanced distally before the staple cartridge spent 30320 is replaced. In this way, the 30327 ramp acts as a spent cartridge lock. In at least one alternative embodiment, ramp 30327 is configured to break away from cartridge body 30322 to release firing member 30040.

[0402] In addition to the above, the locking arrangement of the 30300 stapling instrument also acts as an improper/incompatible cartridge lock. If an unsuitable or incompatible staple cartridge that does not have the 30327 ramp, or another properly configured ramp, were to be seated in the 30010 cartridge channel, the 30040 firing member would not be lifted over an unsuitable staple cartridge slider. and instead the locking pins 30045 would be forced into the locking window 30012 thereby locking the staple firing system. In such instances, the firing member 30040 can be retracted back to its unfired position and the unsuitable/incompatible staple cartridge can be replaced with a suitable/compatible staple cartridge. The accidental exchange of an unsuitable staple cartridge for a suitable staple cartridge can happen in an operating room where certain staple cartridges are intended to be used only with certain stapling instruments, among other cases.

[0403] As discussed above, ramp 30327 extends behind slider 30030. As a result, ramp 30327 can protect slider 30030 from being accidentally pushed distally. In many cases, the 30320 staple cartridge is loaded into the 30300 stapling instrument by inserting the proximal end of the 30320 staple cartridge into the 30010 cartridge channel first and then seating the 30320 staple cartridge into the cartridge channel. 30010. As such, the possibility exists that the slider 30030 will contact the cartridge channel 30010, for example, and will be pushed distally into the staple cartridge 30320 from its proximal unfired position. In such cases, the 30030 slider may no longer be positioned to override the staple firing latch of the 30300 stapling instrument when the staple firing stroke is initiated, and therefore the staple firing latch will treat that cartridge. 30320 staples as worn and will need to be replaced to use the 30300 stapling instrument. The 30327 ramp can prevent this as it extends proximally behind the 30030 slider and can prevent the 30030 slider from being pushed distally into the staple cartridge 30320 when the 30320 staple cartridge is being installed.

[0404] As discussed above, the slider 30030, when properly positioned on the staple cartridge, overcomes the staple firing lock of the stapling instrument so that the staple firing stroke can be completed. In use, the 30040 triggering member is advanced distally, at least partially, to assess whether or not the 30030 slide is properly positioned and that the staple trigger lock has been overcome. More specifically, the 30040 triggering member is advanced distally until the 30040 triggering member is supported by the 30030 slider to execute the staple firing stroke - if the 30030 slider is properly positioned on the 30320 staple cartridge - or comes in contact with the 30015 locking shoulder if the 30030 slider is not properly positioned on the 30320 staple cartridge or the 30320 staple cartridge is not in the cartridge channel

30010. If the 30040 triggering member contacts the 30015 locking lug, the 30040 triggering member may need to be retracted to be able to insert an unspent 30320 staple cartridge into the 30010 cartridge channel and/or retract to start another staple shooting course. With this in mind, the surgical instrument 30400 of Figures 134 and 135 is configured to limit movement of a firing member so that the firing member can be stopped before it reaches the locking lug 30015 if the firing cartridge staples is missing from the cartridge channel, as discussed in more detail below.

[0405] The trigger member 30440 of the surgical instrument 30400, in addition to the above, is similar to the trigger member 30040 in many respects, but comprises a cutting member 30442 that includes secondary locking pins 30449 that extend laterally from the same. If the 30320 staple cartridge is not positioned in the 30410 cartridge channel of the 30400 stapling instrument, the 30442 cutting member will immediately enter the 30012 locking window when the 30440 triggering member is advanced and dis-

then the 30449 secondary locking pins will quickly come into contact with a 30419 secondary locking boss on the 30012 locking window. That way, if a 30320 staple cartridge is not present in the 30410 cartridge channel, the firing member 30440 will not need to move distally until it contacts the locking lug 30015. In such cases, the distance the trigger member 30440 needs to be retracted is at least reduced. In certain instances, the secondary locking shield 30419 is positioned so that the cutting member 30442 does not need to be retracted. In such cases, as a result, an unspent staple cartridge 30320 can be inserted into channel 30410 and the staple firing stroke can be completed without having to retract the firing member 30440.

[0406] In addition to the above, the interaction between the locking pins 30449 and the locking boss 30419 provides a missing cartridge lock. If the staple cartridge 30320 is seated in the cartridge channel 30410, the cutting member 30442 engages the ramp 30327 of the staple cartridge 30320 which lifts the locking pins 30449 over the locking shoulder 30419. In other words , the presence of the 30320 staple cartridge in the 30010 cartridge channel overrides the staple trigger secondary interlock. That said, the slider 30030 of the 30320 staple cartridge needs to be properly positioned on the 30320 staple cartridge for the staple firing stroke to be completed since the nose 30043 of the 30442 cutting member still needs to land on the 30033 shoulder. of slider 30030 so that locking pins 30045 are lifted up onto locking shoulder 30015 as described above. Put another way, the presence of the 30030 slider on the 30320 staple cartridge in its unfired position overrides the primary-fire latch, and the presence of the 30320 staple cartridge in the 30410 cartridge channel overcomes the secondary-fire latch. Thus, the 30400 stapling instrument comprises a primary missing cartridge lock and a secondary missing cartridge lock, with the primary missing cartridge lock also serving as a spent cartridge lock.

[0407] A 30500 surgical stapling set is illustrated in Figure 136. The 30500 stapling instrument is similar to the 30000 stapling instrument in many respects. Among other things, the stapling instrument 30500 comprises a cartridge channel 30510, a staple cartridge 30520 detachably positionable in the cartridge channel 30510, a firing member 30040 and a staple firing lock 30514. 30514 staple firing comprises a resilient metal spring, for example, mounted in cartridge channel 30510. That said, the 30514 staple firing latch can be comprised of any suitable material. The 30514 staple firing latch comprises a base mounted to the 30510 cartridge channel and flexible latch arms 30516 that extend from the base. Each flexible locking arm 30516 moves independently of the other and comprises a locking window 30515 defined therein that is configured to receive and releasably capture a locking pin 30045 extending from the locking member. 30040 trigger. Flexible locking arms 30516 are configured so that they extend inwardly toward and/or against the side of triggering member 30040 and are thereby prone to capture locking pins 30045. When one or both 30045 locking pins are captured in a 30515 locking window, the 30040 staple firing member is prevented from being advanced distally through a staple firing stroke.

[0408] In addition to the above, the staple cartridge

30520 comprises a cartridge body 30522, staple cavities defined in the cartridge body 30522, and staples removably stored in the staple cavities. Staple cartridge 30520 further comprises a tray 30024 attached to cartridge body 30522 and a slider configured to travel distally within the staple cartridge 30520 to eject staples from staple cavities during a staple firing stroke. Similar to the above, the triggering member 30040 is configured to push the slider distally to perform the triggering stroke of staples after the triggering member 30040 has been unlocked. To that end, with reference to Figures 136 and 139, cartridge body 30522 comprises projections, or keys, 30526 which extend proximally therefrom which are configured to engage lock arms 30516 when the cartridge clips 30520 is seated in cartridge channel 30510. In particular, the ends of the lock arms 30516 flare outwards so that when the projections 30526 contact the lock arms 30516, the lock arms 30516 are not trapped. between the projections 30526 and the trigger member 30040. As a result, the projections 30526 flex the locking arms 30516 laterally outward so that the locking pins 30045 extending from the triggering member 30040 are not more positioned in the 30515 lock windows of the 30514 trigger lock when the 30520 staple cartridge is seated in the 30510 cartridge channel. In this way, the act of seating the 30520 staple cartridge in the 30520 30510 cartridge unlocks the 30500 stapling instrument.

[0409] In the event that a 30520 staple cartridge is not seated in the 30510 cartridge channel as discussed above, the 30040 firing member remains locked by the 30514 firing lock and the 30500 stapling instrument cannot be used to staple. the patient's tissue. If a staple cartridge is seated in the 30510 cartridge channel that does not have the 30526 projections, or keys, such as the 30020 staple cartridge, for example, it will not unlock the 30514 trigger lock, as illustrated in Figs. ras 137 and 138, and as a result, the stapling instrument 30500 can be used to staple patient tissue. As shown in Figures 137 and 138, the proximal end of the cartridge body 30022 does not engage, and/or sufficiently displace, the lock arms 30516. Thus, in the present example, the staple cartridge 30020 would be a staple cartridge. unsuitable as it does not unlock the staple trigger trigger of the stapling instrument 30500 and correspondingly the 30520 staple cartridge would be a suitable staple cartridge as it can unlock the staple trigger trigger of the stapling instrument. 30500 stapling lock. As such, the 30514 firing lock is both a missing cartridge lock and an improper cartridge lock. The stapling instrument 30500 may additionally comprise a spent cartridge lock. In the event that an unsuitable staple cartridge is seated in the 30500 stapling instrument and the 30500 stapling instrument cannot be fired, the unsuitable staple cartridge can be removed and a suitable staple cartridge, i.e. a cartridge 30520 staple clamp, can be seated on the 30500 stapling instrument to unlock the staple trigger.

[0410] As discussed above in connection with the stapling instrument 30000, again with reference to Figure 121, the locking pins 30045 of the firing member 30040 engage the locking shoulder 30015 if the slider 30030 is not in its correct position on the cartridge of staples 30020. As also discussed above, the triggering member 30040 of the stapling instrument 30000 is advanced distally before engaging the locking shoulder 30015 and thus has time to accelerate before contacting the locking shoulder 30015. As such, the firing member 30040 of the stapling instrument 30000 can collide with the locking shoulder at 30015 with significant velocity and energy. As such, the 30015 Lock Shoulder is robustly designed to absorb this impact; however, there is a possibility that the triggering member 30040 may collide with the locking shoulder or the locking shoulder 30015 fails, thereby accidentally overriding the staple triggering lock of the stapling instrument 30000. crash 30514 of Figures 136 and 137 can reduce, if not eliminate, these potential problems. For example, the 30515 locking windows of the 30514 triggering lock are sized and configured to prevent a small, if any, proximal or distal translation of the 30040 staple triggering member while the 30516 locking arms are engaged with the locking pins. 30045 and thus the staple firing member 30040 has little, if any, time to accelerate before being stopped by the distal ends of the latch windows 30515. Furthermore, after the latch pins 30045 engage the distal ends of the latch windows 30045. 30515 locking windows, 30516 locking arms are placed under tension and, as a result, are able to withstand significant loads before they fail, if failures do occur.

[0411] As discussed above, both locking arms 30516 are disengaged from firing member 30040 by cartridge body 30522 when staple cartridge 30520 is seated in stapling instrument 30500. That said, alternative arrangements are provided in which a first component of a staple cartridge unlocks a first latch arm 30516 and a second component of the staple cartridge unlocks a second latch arm 30516 when the staple cartridge is seated in the stapling instrument 30500. For example, a body cartridge slider can unlock the first lock arm 30516 and a staple cartridge slider can unlock the second lock arm

[0412] A 30600 surgical stapling instrument is illustrated in Figure 140 and a 30700 surgical stapling instrument is illustrated in Figure 141. The 30600 and 30700 stapling instruments are similar to the 30500 stapling instrument in many respects. Referring to Figure 140, the stapling instrument 30600 comprises a cartridge channel 30610, a staple cartridge 30620 detachably positionable in the cartridge channel 30610, and a staple firing lock 30614 mounted on the cartridge channel. 30610 which prevents the 30040 firing member from being advanced through a staple firing stroke unless the 30620 staple cartridge is seated in the cartridge channel

30610. Similarly, with reference to Figure 141, the stapling instrument 30700 comprises a cartridge channel 30710, a staple cartridge 30720 removably positioned in the cartridge channel 30710, and a staple firing latch 30714 mounted in the channel. cartridge 30710 which prevents the 30040 firing member from being advanced through a staple firing stroke unless the 30720 staple cartridge is seated in the 30710 cartridge channel. In particular, however, cartridge seating of staples 30720 in the stapling instrument 30600 does not unlock the staple firing system of the stapling instrument 30600 and likewise the seating of the staple cartridge.

pos 30620 on the stapling instrument 30700 does not unlock the staple triggering system of the stapling instrument 30700. In this way, the stapling instruments 30600 and 30700 can be used in the same operating room at the same time without the possibility of be used with the wrong staple cartridge, even though the 30620 and 30720 staple cartridges are very similar.

[0413] Referring to Figure 142, in addition to the above, the staple cartridge 30620 further comprises a cartridge body 30622 that includes a proximal end 30626 that is angled so that the center of the cartridge body 30622, that is, the portion closest to the longitudinal slot 30023, extends more proximally than on the side sides of the cartridge body 30622. The staple cartridge 30620 additionally comprises a slider 30630, which is similar to slider 30030 in many ways. aspects, which comprises a proximal end 30636 that has a profile that corresponds, or at least substantially corresponds, to the profile of the proximal end 30626 of the cartridge body 30622. Again referring to Figure 140, the firing lock 30614 is similar to the trigger lock 30514. Among other things, trigger lock 30614 comprises lock arms 30616 that releasably hold trigger member 30040 in its unfired position until the 30616 lock arms are displaced laterally by the proximal end of the 30622 cartridge body and/or the proximal end of the 30630 slider to release the 30045 lock pins from the lock windows defined in the 30616 lock arms. of staples 30620 is removed from cartridge channel 30610, lock arms 30616 resiliently return to their locked position.

[0414] Referring to Figure 143, in addition to the above, the staple cartridge 30700 further comprises a cartridge body 30722 that includes a proximal end 30726 that is angled so that the side sides of the cartridge body 30722 , i.e., the most distant portions of longitudinal slot 30023, extend more proximally than the center of cartridge body 30722. Staple cartridge 30720 further comprises a slider 30730, which is similar to slider 30030 in many respects, comprising a proximal end 30736 that has a profile that matches, or at least substantially matches, the profile of the proximal end 30726 of the cartridge body 30722. Again with reference to Figure 141, the firing lock 30714 is similar to the firing lock 30714. trigger 30514. Among other things, the trigger lock 30714 comprises locking arms 30716 that releasably hold the trigger member 30040 in its undisclosed position. until the 30716 lock arms are displaced laterally by the proximal end of the 30722 cartridge body and/or the proximal end of the 30730 slider to release the 30045 lock pins from the lock windows defined in the 30716 lock arms. If the 30720 staple cartridge is removed from the 30710 cartridge channel, the 30716 lock arms resiliently return to their locked position.

[0415] In particular, in addition to the above, the proximal end of the staple cartridge 30620 would not displace, or at least sufficiently displace, the locking arms 30716 of the trigger lock 30714 to disengage the trigger lock 30714 from the trigger member. - stop 30040 if the 30620 staple cartridge is seated in the 30700 stapling instrument. Also, the proximal end of the 30720 staple cartridge would not displace, or at least sufficiently displace, the locking arms 30616 of the 30616 locking device. 30614 trigger to disengage the 30614 trigger lock from the 30040 trigger member if the 30720 staple cartridge is seated in the 30600 stapling instrument. In this way, each staple cartridge

30620 and 30720 comprise unique switching features that unlock their respective, or correct, instruments, or stapling instruments.

[0416] In many cases, in addition to the above, the cartridge body and/or slider of a staple cartridge, or staple cartridge type, may comprise one or more unique keying features that can only unlock its respective stapling tool. In certain cases, the tray that extends under the cartridge body may comprise a proximal feature, or key, configured to unlock the staple trigger of your stapling instrument. Referring to Figure 144, a cartridge tray 30824, which is similar to tray 30024 in many respects, comprises a proximal projection, or key, 30826 configured to unlock the staple firing drive of a stapling instrument. The 30826 projection is comprised of sheet metal folded to form a tubular structure, for example. The tubular frame is reinforced by a nested interconnect that includes a tab 30827 and a slot 30828.

[0417] A 30900 surgical stapling instrument is illustrated in Figures 145 and 147 and a 31000 surgical stapling instrument is illustrated in Figure 148. The 30900 and 31000 stapling instruments are similar to the 30500 stapling instrument in many respects. Referring to Figure 145, the stapling instrument 30900 comprises a cartridge channel 30910, a staple cartridge 30920 detachably positionable in the cartridge channel 30910, and a staple firing latch 30914 mounted on the cartridge channel 30910 that prevents the 30040 firing member from being advanced through a staple firing stroke unless the 30920 staple cartridge is seated in the cartridge channel

30910. Similarly, with reference to Figure 148, the stapling instrument 31000 comprises a cartridge channel, a staple cartridge 31020 detachably positionable in the cartridge channel, and a staple firing latch 31014 mounted in the cartridge channel. which prevents the firing member 30040 from being advanced through a staple firing stroke unless the staple cartridge 31020 is seated in the cartridge channel.

[0418] In particular, the staple firing latch 30914 comprises only one latch arm 30916 extending along the right side of the firing member 30040. That said, the one latching arm 30916 comprises a latching window defined in the which is configured to capture and hold a locking pin 30045 properly of the firing member 30040 to secure the firing member 30040 in its unfired position, as illustrated in Figure 147, until the staple cartridge 30920 is seated in the firing channel. cartridge 30910, as illustrated in Figure 145. More specifically, the cartridge body 30922 of the staple cartridge 30920 comprises a proximal projection, or key, 30926 that extends from the right side of the cartridge body 30922 that engages the arm. 30916 lock arm and flexes the 30916 lock arm laterally as the 30920 staple cartridge is seated in the cartridge channel

30910. In particular, cartridge body 30922 may not comprise a projection, or key, 30926 extending from the left side of cartridge body 30922.

[0419] Furthermore, in particular, the 31014 Clamp Fire Lock comprises only one Latch Arm 31016 that extends along the left side of the 30040 Fire Member. That said, the one Latch Arm 31016 comprises a locking window defined therein which is configured to capture and hold a locking pin 30045 suitably of the firing member 30040 to secure the firing member 30040 in its unfired position, as illustrated in Figure 148, until the staple cartridge 31020 is seated in the cartridge channel of the stapling instrument 31000. More specifically, the cartridge body 31022 of the staple cartridge 31020 comprises a proximal projection, or key, 31026 that extends from the left side of the body. cartridge 31022 that engages lock arm 31016 and flexes lock arm 31016 laterally outward when staple cartridge 31020 is seated in stapling instrument 31000. In particular, the c Cartridge body 31022 may not comprise a projection, or key, 31026 that extends from the right side of cartridge body 31022.

[0420] Due to the asymmetry of the 30922 and 31022 cartridge bodies and the corresponding asymmetry of the 30914 and 31014 staple firing interlocks, seating the 31020 staple cartridge in the 30900 stapling instrument does not unlock the staple firing system of the 30900 stapling instrument and likewise, seating the 30920 staple cartridge in the 31000 stapling instrument does not unlock the staple firing system of the 31000 stapling instrument. As such, the 30900 stapling instruments and 31000 can be used in the same operating room at the same time without the possibility of being used with the wrong staple cartridge, although the 30920 and 31020 staple cartridges are very similar. In some cases, the staple pattern produced by the 30920 staple cartridge is different from the staple pattern produced by the 30120 staple cartridge, and as a result, the anvil of the 30900 stapling instrument will have a different arrangement of anvil forming pockets. of the stapling instrument 31000. In such cases, the asymmetric trigger/key locking arrangements disclosed herein may prevent a mismatch between the arrangement of staple cavities and the arrangement of staple forming pockets.

[0421] Referring to Figures 149 and 150, a staple cartridge 31120 comprises a cartridge body 31122 that includes longitudinal parallel rows of staple cavities while a staple cartridge 31220 comprises a cartridge body 31222 that includes rows of clamp cavities oriented in transverse directions. Similar to the above, with reference to Figure 149, the proximal end of cartridge body 31122 comprises keys 31126 that extend from the left side of cartridge body 31122 - but not the right or opposite side of the cartridge body 31122 - and the proximal end of cartridge body 31222, with reference to Figure 150, comprises keys 31226 that extend from the right side of the cartridge body 31222 - but not the left side of the cartridge body

31222. The 31120 staple cartridge (Figure 149) is used with a first stapling instrument that has parallel longitudinal rows of anvil staple forming pockets and a left-side staple firing lock, such as the trigger lock 31014 (Figure 148), for example. The 31220 staple cartridge (Figure 150) is used with a second stapling instrument that has longitudinal rows of anvil staple forming pockets and a right-hand staple trigger lock, like the 30914 trigger lock. (Figure 147), for example. The 31220 staple cartridge does not unlock the first stapling instrument and similarly the 31120 staple cartridge does not unlock the second stapling instrument. As such, the keys 31126 of the 31120 staple cartridge cannot unlock a stapling instrument that has staple forming pockets that extend in transverse directions, and accordingly, the keys 31226 of the 31220 staple cartridge cannot unlock an instrument. stapling bag which has staple forming pockets that extend in parallel longitudinal rows.

[0422] In particular, the staple cartridge 31120 and the staple cartridge 31220 are substantially the same length and substantially the same shape. In addition, the 31120 and 31220 staple cartridges are both configured to produce staple lines in patient tissue that are approximately 60 mm in length. However, the 31120 and 31220 staple cartridges could both be configured to produce staple lines that are approximately 30mm long or 45mm long, for example. Furthermore, it is entirely possible for cartridge body 31122 and cartridge body 31222 to be the same color. In many cases, a commercial supplier may color-code the cartridge bodies of the staple cartridges they sell to indicate the size of staples stored in them. For example, cartridge bodies containing unformed staples having an unformed staple height of approximately 4 mm are green, for example. Cartridge bodies containing unformed staples having an unformed staple height of approximately 2.5 mm may be white, for example. Therefore, it is entirely possible for the 31120 and 31220 staple cartridges to be the same color. As such, it is possible for a clinician to pick up one staple cartridge when he intended to pick up the other and install the staple cartridge in the wrong stapling instrument. The improvements disclosed in the present invention take these possibilities into account and lock the stapling instrument in such cases.

[0423] A 30800 surgical instrument is illustrated in Figures 151 to

155. Referring primarily to Figures 153 and 154, the surgical instrument 30800 comprises a cartridge channel 30810, a staple cartridge 30820 removably positioned in the cartridge channel 30810, a firing member 30040, and a lock 30814 mounted on the channel. cartridge 30810. Lock 30814 comprises a spring bundle 30816 that includes a proximal end anchored in an opening defined in cartridge channel 30810 and a distal end that is movable with respect to the fixed proximal end. Referring primarily to Figures 153 and 155, the lock 30814 additionally comprises a lock box 30815 configured to capture one of the lock pins 30045 that extend from the cutting portion 30042 of the trigger member 30040 and hold the trigger member 30040. 30040 trigger in a non-triggered position when the 30820 staple cartridge is not seated in the 30810 cartridge channel. The 30815 lock box comprises a distal wall configured to prevent the 30040 triggering member from being advanced distally, a proximal wall configured to prevent the trigger member 30040 from retracting proximally, and a bottom wall that connects the proximal wall and the distal wall of the 30815 lock box. The top of the 30815 lock box, however, is open but could be closed.

[0424] The staple cartridge 30820 comprises a cartridge body 30822, a slider, and a tray 30824 attached to and extending under the cartridge body 30822. In addition to the above, the tray 30824 comprises a proximal projection. 30826 configured to engage the 30816 spring bundle of the 30814 lock when the 30820 staple cartridge is seated in the 30810 cartridge channel as illustrated in Figures 152 and 154. When the 30826 projection contacts the spring bundle 30816, the spring bundle 30816 flexes laterally so that the locking pin 30045 is no longer captured in the locking box 30815 of the locking 30814. At that point, the triggering member 30040 has been unlocked and the triggering member 30040 can be advanced distally to perform a staple firing stroke. Referring primarily to Figure 154, the distal, or free, end of spring bundle 30816 extends into a window 30819 defined in cartridge channel 30810. Window 30819 provides clearance for spring bundle 30816 when the bundle 30816 is flexed by the staple cartridge 30820. In addition, a bottom side wall of the window 30819 supports the distal end of the spring bundle 30816 so that the distal end is at least simply supported. In any case, the 30814 lock provides a missing cartridge lock and a cartridge lock that is unsuitable for staple cartridges, such as the 30020 staple cartridge, that do not have a proper key to unlock the 30800 stapling instrument.

[0425] As discussed above, the lock 30814 is moved from a locked position (Figures 152 and 153.) to an unlocked position (Figure 154) when the staple cartridge 30820 is seated in the cartridge channel 30810 of the stapling instrument 30800. This deflection is seen in Figure 155 which illustrates the 30814 lock in its locked position on solid lines and its unlocked position on imaginary lines. In cases where an inadequate or incompatible staple cartridge, i.e. a staple cartridge that does not have a suitable key, is seated in cartridge channel 30810, the spring bundle 30816 will not be deflected, or at least adequately deflected, to unlocking the firing member 30040. In particular, the latch 30814 further comprises a tab 30817 that extends from the spring bundle 30816 so that the tab 30817 moves laterally with the spring bundle 30816 when the latch 30814 is deflected. When the lock 30814 is in its locked position, as illustrated in Figure 153, the tab 30817 prevents the anvil of the surgical instrument 30800, i.e. the anvil 30050, from being moved to a closed position, or fully secured, as described in more detail below.

[0426] The 30050 anvil is pivotally coupled to the car-

tappet 30810 around pivot pins 30051 mounted in defined openings in cartridge channel 30810. When anvil 30050 is rotated towards cartridge channel 30810 by a surgical instrument closure system 30800, and cartridge staples 30820 is not seated in cartridge channel 30810, a bottom surface 30057 of anvil 30050 contacts tab 30817 and anvil 30050 is prevented from being moved to its closed or fully secured position. When the staple cartridge 30820 is seated in the cartridge channel 30810, however, the tab 30817 is displaced laterally so that when the anvil 30050 is closed, the anvil 30050 does not contact the tab 30817 and the anvil 30050 can be moved to its closed or fully secured position. Thus, lock 30814 also comprises a closing anvil lock since lock 30814 prevents the anvil 30050 from being closed when the staple cartridge 30820 is not seated in the cartridge channel.

30810. In such cases, the clinician will quickly become aware that an improper staple cartridge is positioned in the 30810 cartridge channel and/or that a staple cartridge is missing as he will not be able to close the 30050 anvil. Since the 30050 anvil cannot be closed over tissue, the staple firing stroke of the 30800 stapling instrument would also be avoided in such cases. In alternative embodiments in which the staple cartridge jaw is pivotable instead of the anvil, such a lock could be used to prevent the staple cartridge jaw from being rotated to a closed position or fully clamped if an ineffective staple cartridge fails. is positioned in the staple cartridge jaw or a staple cartridge is missing from the cartridge jaw.

[0427] As discussed above, Lock 30814 is configured to resist closing of Anvil 30050. To this end, in addition to the above, the proximal end of Lock 30814 is fixedly supported in cartridge channel 30810 and the distal end of the 30814 lock is simply supported by the side walls of the 30819 window. This is the case when the 30814 lock is in both its locked (Figure 153) and unlocked (Figure 154) configurations. As such, the 30814 lock can act as a beam supported at both ends and is well suited to support the clamping load applied by the 30050 anvil. Similarly, the tab 30817 extending from the 30814 lock is also supported by the 30810 cartridge. More specifically, tab 30817 is slidably supported in a slot 30818 defined in cartridge channel 30810 when lock 30814 is in both its locked (Figure 153) and unlocked (Figure 154) configurations. . As such, the 30814 lock can act as a beam supported at both ends and an intermediate position and is well suited to withstand the clamping load applied by the anvil.

30050. That said, any suitable support arrangement could be used.

[0428] As discussed above, the lock 30814 is configured to prevent the anvil 30050 of the stapling instrument 30800 from being moved to a closed position, or fully secured, when the staple cartridge 30820 is not seated in the cartridge channel 30810. Said that is, the lock 30814 is configured to prevent the anvil 30050 from being substantially closed when the staple cartridge 30820 is not seated in the cartridge channel 30810. In such cases, the anvil 30050 can be moved slightly towards the cartridge channel 30810; however, anvil 30050 visibly opens when anvil 30050 contacts tab 30817 of the lock

30814. In several alternative embodiments, the 30050 anvil is prevented from moving until the 30820 staple cartridge is seated in the 30810 cartridge channel. In either case, the 30800 stapling instrument is not insertable into a patient via of a trocar when the 30050 anvil is locked. More specifically, a trocar comprises an internal passage, or cannula, which is sized and configured to closely receive a surgical instrument therein and, when the anvil 30050 is locked as described above, the distance between the anvil 30050 and the cartridge channel 30810 is too large for the 30800 stapling instrument to fit through the inner passage. As a result, in such cases, the physician using the 30800 stapling instrument will become aware that an inappropriate staple cartridge is positioned in the 30800 stapling instrument before the 30800 stapling instrument is inserted into the patient.

[0429] A 31520 staple cartridge is illustrated in Figure 155A. The staple cartridge 31520 comprises a cartridge body 31522 and a tray 31524 attached to the cartridge body 31522. Tray 31524 comprises locking arms 31521 engaged with side channels defined in cartridge body 31522 that secure tray 31524 to the cartridge body. cartridge 31522. Tray 31524 is comprised of stamped metal, such as stainless steel, for example. Tray 31524 comprises two side sides - one on each side of longitudinal slot 30023. Each side side of tray 31524 extends along a side side of cartridge body 31522 and under a portion of cartridge body 31522. Each side side of tray 31524 further comprises a proximal end 31527 that wraps around the proximal end of cartridge body 31522. The proximal ends 31527 extend orthogonally, or at least substantially orthogonally, to the lateral sides of the tray.

31524. Each proximal end 31527 comprises a tab that is bent to form a proximally extensible key 31526. Similar to the above, keys 31526 are configured to unlock a staple firing system of a stapling instrument when the staple cartridge 31520 is seated in the stapling instrument.

[0430] In addition to the above, each key 31526 comprises a rounded proximal end created by bending the tabs outward so that the tab ends are brought back into contact with the proximal end 31527. As a result, 31526 keys are strong and deflection of 31526 keys is avoided, or at least substantially reduced. As such, the 31526 keys will reliably deflect the trigger locks to unlock the trigger system when the 31520 staple cartridge is seated in the stapling instrument. Each proximal end 31527 further comprises one or more retaining teeth 31529 that extend into slots 31528 defined in proximal end 31527. Slots 31528 facilitate flexing of proximal ends 31527 and also prevent, or at least limit, movement. and/or deflection within keys 31526. Teeth 31529 presses proximal end 31527 and holds key 31526 in its bent configuration.

[0431] A 31620 staple cartridge is illustrated in Figure 155B. The staple cartridge 31620 comprises a cartridge body 31522 and a tray 31624 secured to the cartridge body 31522. Tray 31624 comprises locking arms 31621 engaged with side channels defined in cartridge body 31522 that secure tray 31624 to the cartridge body. cartridge 31522. Tray 31624 is comprised of stamped metal, such as stainless steel for example. Tray 31624 comprises two side sides - one on each side of longitudinal slot 30023. Each side side of tray 31624 extends along a side side of cartridge body 31522 and under a portion of cartridge body 31522. Each side side of tray 31624 further comprises a proximal end that wraps down and around the proximal end of cartridge body 31522. The proximal ends extend orthogonally, or at least substantially orthogonally, to the lateral sides of tray 31624. Each end The proximal portion comprises a tab that is bent to form a proximally extensible key 31626. Similar to the above, keys 31626 are configured to unlock a staple firing system of a stapling instrument when the staple cartridge 31620 is seated in the instrument. of stapling.

[0432] In addition to the above, each switch 31626 comprises a side-facing U-shaped channel. More specifically, each key 31626 comprises an inner base 31627, a laterally extending upper side 31628 extending from the inner base 31627, and a laterally extending lower side 31629 extending from the opposite side of the key. 31627 internal base. The U-shape configuration of the 31626 keys prevents bending of the 31626 keys under a longitudinal load and/or deflection under a laterally directed torque. In particular, keys 31626 are bent from tabs extending from tray 31624 to create clearance spans 31625 under keys 31626. Clearance spans 31625 are sized and configured to allow locking pins of a member triggers pass under keys 31626 during a triggering stroke of triggering member clamps.

[0433] A 31720 staple cartridge is illustrated in Figure 155C. The staple cartridge 31720 comprises a cartridge body 31522 and a tray 31724 attached to the cartridge body 31522. Tray 31724 comprises locking arms 31721 and 31721' engaged with side channels defined in cartridge body 31522 that secure tray 31724 to cartridge body 31522. Tray 31724 is comprised of stamped metal, such as stainless steel, for example. Tray 31724 comprises two side sides - one on each side of longitudinal slot 30023. Each side side of tray 31724 extends along a side side of cartridge body 31522 and under a portion of cartridge body 31522. side of tray 31724 further comprises a proximal end 31727 that wraps down and around the proximal end of cartridge body 31522. Proximal end 31727 extends orthogonally, or at least substantially orthogonally, to the lateral side of tray 31724. Proximal end 31727 comprises a tab that is bent to form a proximally extensible key 31726. Similar to the above, key 31726 is configured to unlock a staple firing system of a stapling instrument when the staple cartridge 31720 is seated on the stapling instrument.

[0434] In addition to the above, the lateral side of the tray 31724 comprises an arcuate surface or circular cutout and the proximal end 31727 comprises an arcuate or circular projection 31723 which is flexed around the sides of the cartridge body 31522 into the circular cutout. Projection 31723 is received closely in the cut so that the proximal end 31727 of tray 31724 is greatly stiffened or reinforced by this arrangement. Key 31726 comprises an L-shaped tab flexed proximally from tray 31724. Key 31726 comprises a shoulder 31728 bent up from proximal end 31727 to create this L-shaped configuration shaped configuration. The 31728 shoulder comprises at least one notch, or stress relief, 31729 configured to facilitate bending of the 31726 wrench. The U-shaped configuration of the 31726 wrench prevents bending of the 31726 wrench under a longitudinal and/or longitudinal load. deflection under a laterally directed torque. In particular, key 31726 is bent from a tab that extends from tray 31724 to create a clearance gap 31725 under key 31726. Clearance gap 31725 is sized and configured to allow the locking pin of a firing member passes under key 31726 during a firing stroke of firing member clamps.

[0435] A 31920 staple cartridge is illustrated in Figure 155E. The staple cartridge 31920 comprises a cartridge body 31522 and a tray 31924 attached to the cartridge body 31522. Tray 31924 comprises locking arms 31921 engaged with side channels defined in cartridge body 31522 that secure tray 31924 to the cartridge body. cartridge 31522. Tray 31924 is comprised of stamped metal, such as stainless steel, for example. Tray 31924 comprises two side sides - one on each side of longitudinal slot 30023. Each side side of tray 31924 extends along a side side of cartridge body 31522 and under a portion of cartridge body 31522. side of tray 31924 comprises a proximal end 31927 that wraps around the proximal end of cartridge body 31522. The proximal end 31927 extends orthogonally, or at least substantially orthogonally, to the lateral side of tray 31924. Proximal end 31927 comprises a tab that is bent to form a proximally extensible key 31926. Similar to the above, key 31926 is configured to unlock a staple trigger system of a stapling instrument when the cartridge - cho of staples 31920 is seated in the stapling instrument.

[0436] In addition to the above, key 31926 comprises an L-shaped tab flexed proximally from tray 31924. Key 31926 comprises a shoulder 31928 bent up from proximal end 31927 to create this configuration L-shaped. The U-shaped configuration of the 31926 wrench prevents the 31926 wrench from bending under a longitudinal load and/or deflecting under a laterally directed torque. In addition, a free edge of the 31928 shoulder is welded and/or brazed to the 31927 proximal end to strengthen the 31926 key. That said, any suitable number of 31929 welds can be used to secure or reinforce the 31926 key. In particular, keys 31926 are bent from the tabs extending from tray 31924 to create a clearance gap 31925 under key 31926. Clearance gap 31925 is sized and configured to allow the locking pin of a member trigger passes under key 31926 during a trigger stroke of the triggering member clamps.

[0437] A 31820 staple cartridge is illustrated in Figure 155D. The staple cartridge 31820 comprises a cartridge body 31522 and a tray 31824 secured to the cartridge body 31522. Tray 31824 comprises locking arms 31821 engaged with side channels defined in cartridge body 31522 that secure tray 31824 to the cartridge body. cartridge 31522. Tray 31824 is comprised of stamped metal, such as stainless steel, for example. Tray 31824 comprises two side sides - one on each side of longitudinal slot 30023. Each side side of tray 31824 extends along a side side of cartridge body 31522 and under a portion of cartridge body 31522. side of tray 31824 comprises a proximal end 31827 that wraps around the proximal end of cartridge body 31522. The proximal end 31827 extends orthogonally, or at least substantially orthogonally, to the lateral side of tray 31824. Proximal end 31827 comprises a tab that is bent to form a proximally extendable key 31826. Similar to the above, key 31826 is configured to unlock a staple firing system of a stapling instrument when the cartridge is - cho of staples 31820 is seated in the stapling tool.

[0438] In addition to the above, the key 31826 comprises a rounded proximal end created by bending the tab outwards so that the tab end is brought back into contact with the proximal end 31827. As a result, the 31826 key is strong and deflection of the 31826 key is avoided, or at least substantially reduced. As such, the 31826 key will reliably deflect the firing system latches to unlock the firing system when the 31820 staple cartridge is seated in the stapling instrument. Proximal end 31827 further comprises one or more retaining teeth 31829 that extend into slots 31828 defined in proximal end 31827. Slots 31828 facilitate flexing of proximal end 31827 and also prevent, or at least limit, movement. and/or deflection within the key 31826. The teeth 31829 press the proximal end 31827 and hold the key 31826 in its folded configuration. In particular, key 31826 is bent from a tab that extends from tray 31824 so as to create a clearance gap 31825 under the key.

31826. Clearance gap 31825 is sized and configured to allow the locking pin of a firing member to pass under key 31826 during a firing stroke of firing member clamps.

[0439] Many of the locks disclosed herein are overcome when a compatible or suitable staple cartridge is seated in the stapling instrument. When seated, a staple cartridge is locked into position within the stapling instrument. In such cases, there is little, if any, relative movement possible between the staple cartridge and the stapling instrument until the staple cartridge is uninstalled from the stapling instrument.

[0440] In various cases, a surgical stapling assembly comprises a drive shaft and an end actuator that extends distally from the drive shaft that includes a first jaw and a second jaw pivoting relative to the first jaw. The surgical staple assembly may comprise a locking member configured to prevent accidental firing of the surgical staple assembly and/or tightening of the surgical staple assembly until a locking key unlocks the locking member. The locking key may be a part of a staple cartridge configured to be installed in one of the first jaws and second jaws, for example. Particularly, the locking key may be a part of a staple cartridge slider so that the staple cartridge can unlock the locking member when the slider is in its unfired position, indicating that the staple cartridge it is unworn when the staple cartridge is installed into the surgical stapling assembly. In at least one case, additional action may be required to unlock the lock with the locking key. For example, an end actuator may be required to reach a fully locked configuration before the locking switch can unlock the locking member. An example of a lock can be found in US Patent Application Publication No. 2016/0249921 entitled SURGICAL APPARATUS WITH CONDUCTOR STRAIN RELIEF, now US Patent No. 10,085,749, the disclosure of which is hereby incorporated by reference. , in its entirety.

[0441] In at least one case, surgical stapling sets such as the one described above can be used with a surgical robot. Surgical stapling sets can be configured to be attached to robotic systems and operated via the robotic arms of the robotic systems.

These robotic systems allow surgeons to be outside of a sterile field in which the patient is present.

In at least one case, a technician and/or another surgeon, for example, may be situated within the confines of the sterile field to monitor the interface between the tools and the patient.

This technician and/or surgeon may attach the instruments to the robotic arms or release them from the robotic arms during a surgical procedure.

In some cases, it may be advantageous to be able to actively deactivate the locking member of a surgical stapling set.

Providing this capability can allow a surgeon or technician to manually override a locking means of a staple cartridge when the locking means, for whatever reason, cannot be automatically overridden.

Providing this capability may also allow a surgeon to test the operability of the locking member to ensure that the locking member is functional before using the surgical stapling set.

In a case where the surgeon wants to manually override the locking member to fire a staple cartridge, a surgeon or physician may know that the staple cartridge installed is a suitable, unfired staple cartridge and may want to fire the cartridge. of staples irrespective of the fact that the locking member was not actually overcome.

In at least one case, the clinician may want to remove this locking member from the firing sequence and prevent it from being a part of the firing course.

In addition, providing direct access to the locking member within the end actuator itself for manual unlocking can provide an advantage with or without a system that automatically disables the locking member.

Direct access to the locking member within the end actuator can eliminate additional components that might otherwise be present in a system that uses an unlocking mechanism to unlock the locking member that is further upstream of the locking member. The use of an unlocking mechanism further upstream of the locking member within the surgical instrument shaft, for example, may introduce additional components that could jam or fail during application of an unlocking actuation.

[0442] Figures 156 to 160 depict a 41000 surgical staple set configured to clamp, staple, and cut a patient's tissue. The 41000 Surgical Stapling Assembly is configured to be attached to, detached from, and operated by a surgical robot and/or a surgical instrument handle. The surgical staple assembly 41000 comprises a drive shaft 41100, a first jaw 41200 pivotally supported within the drive shaft 41100, and a second jaw 41300 secured to the drive shaft 41100. The first jaw 41200 is movable between an unclamped configuration and a clamped configuration for clamping and releasing tissue positioned between the first jaw 41200 and the second jaw 41300. The surgical instrument assembly 41000 further comprises a staple cartridge 41230 comprising a plurality of clips removablely stored therein. The 41230 staple cartridge is configured to be installed inside the first 41200 jaw and replaced with other staple cartridges. The surgical stapling assembly 41000 further comprises a triggering member 41400 which extends through the drive shaft 41100 which is configured to move the first jaw 41200 with respect to the second jaw 41300 between the unfixed configuration and the secured configuration. staple cartridge 41230 and cut the tissue during a firing stroke with a knife, or blade, 41422. The firing member 41400 is configured to be driven by a surgical robot drive system and/or an instrument handle surgical. Embodiments are provided in which the firing member 41400 is driven with a rotating drive shaft. Modalities are also contemplated in which the jaw configured to receive the staple cartridge is fixed to the drive shaft and the jaw containing the anvil is movable between a clamped configuration and an unclamped configuration.

[0443] The 41000 Surgical Staple Assembly additionally comprises a 41500 Lock (Figure 160) configured to prevent the 41400 Trigger Member from moving distally beyond a specific position unless a suitable unused staple cartridge is installed in the first jaw 41200 and the first 41200 grip is in a fully clamped configuration. In at least one case, the trigger member 41400 is permitted to move a first distance between a home position and the specific position regardless of the condition of the lock 41500 to allow for tissue attachment and release, as discussed in greater detail below. The lock 41500 is biased towards a locked configuration in which the trigger member 41400 is prevented from moving distally beyond the specified position. The 41500 Lock is movable in an unlocked configuration in which the 41400 triggering member is allowed to move distally beyond the specific position to deploy staples from the staple cartridge

41230. As discussed in greater detail below, the surgical staple assembly 41000 additionally comprises a right access hole defined therein configured to allow a clinician to manually, or artificially, unlock the lock 41500, i.e., move the lock 41500 to the unlocked configuration.

[0444] The first jaw 41200 comprises a channel 41210 configured to receive the staple cartridge 41230 therein. The 41230 staple cartridge is configured to be installed into the 41210 channel and readily replaced with another staple cartridge. The staple cartridge 41230 further comprises a slider 41235 movable between a non-fired position and a fired position to eject staples from the staple cartridge 41230 as the slider 41235 is pushed distally through a cartridge body 41232 of the staple cartridge 41230. staples 41230 by firing member 41400. Second jaw 41300 comprises an anvil 41320 comprising a staple forming surface 41310 configured to form staples ejected from staple cartridge 41230.

[0445] The first jaw 41200 is movable with respect to the second jaw 41300 between an unclamped configuration and a configuration held by the firing member 41400. Embodiments are contemplated in which the second jaw 41300 is movable with respect to the first jaw

41200. To grip the tissue, the trigger member 41400 is moved a first distance distally from an initial position to eccentrically actuate the first jaw 41200 in a gripped configuration. Referring to Figure 159, firing member 41400 comprises anvil cam portions 41423 configured to engage a ramp 41332 of an anvil channel 41330 defined within second jaw 41300 and channel cam portions 41424 configured to engage a ramp. 41222 of a bottom surface 41220 of first jaw 41200. Anvil cam portions 41423 and channel cam portions 41424 extend laterally from a distal portion 41420 of firing member 41400 and are configured to controlling the distance between the first jaw 41200 and the second jaw 41300 as the distal portion 41420 of the triggering member moves through its triggering path. During the first distance discussed above, the anvil cam portions 41423 and the channel cam portions 41424 engage the first and second jaws 41200, 41300 and cam the first jaw 41200 into a locked configuration. Further distal movement of the distal portion 41420 of the triggering member 41400 retains the first and second jaws 41200, 41300 relative to each other during the triggering stroke and pushes the slider 41235 distally to eject the staples stored within the trigger. 41230 staple cartridge.

[0446] The 41000 Surgical Stapling Assembly additionally comprises a 41500 Lock configured to prevent the triggering member from being advanced distally beyond the first distance unless a suitable unused staple cartridge is installed within the first jaw 41200 and the first jaw 41200 is fully engaged. The lock 41500 comprises a lock member 41510 pivotally supported within the drive shaft 41100 and movable between an unlocked configuration (Figure 157) in which the firing member 41400 is allowed to move beyond the first distance to complete the stroke. trigger and a locked configuration (Figure 158) in which the trigger member 41400 is prevented from moving beyond the first distance. Locking member 41510 is biased to the spring-locked configuration 41520. A suitable unspent staple cartridge installed within channel 41210 can overcome the bias provided by spring 41520 when first jaw 41200 is moved to the stuck configuration.

[0447] To unlock the 41500 latch, the 41200 first jaw needs to be moved to its gripped configuration to introduce the 41235 slider to engage and unlock the 41510 locking member. The 41235 slider cannot override the 41500 lock when the first jaw 41200 is not in its stuck configuration. Modalities are envisaged in which the cartridge grip is not pivotable but the anvil grip is pivotable. In such embodiments, the mere insertion of the staple cartridge features the 41235 slider to overcome the locking.

41500. In such embodiments, the lock 41500 may be overcome prior to the application of any gripping movement of the anvil grip.

[0448] To unlock the latch 41500, as discussed above, a suitable unspent staple cartridge must be installed in the first jaw 41200 of the surgical stapling assembly 41000. The staple cartridge 41230 comprises a slider 41235 which comprises a lock 41237 that extends proximally therefrom. The 41237 locking switch is configured to move the 41510 locking member to the unlocked configuration when the 41235 slider is in a non-triggered position and the 41200 first jaw is moved to the locked configuration. To unlock the lock, the 41237 locking key pivots the 41510 locking member to the unlocked configuration by moving a locking boss, or leg, 41511 of the 41510 locking member away from a locking notch 41412 defined on a drive shaft. , or bar, trigger 41410 of trigger member 41400 that would otherwise prevent distal movement of trigger member 41400 beyond an initial distance used to clamp when first jaw 41200 is moved to the clamped configuration. Locking member 41510 comprises a pair of arms 41512 extending distally from locking lug 41511 that are configured to seat triggering member 41400 as triggering member 41400 moves through its triggering path. .

[0449] Figure 157 illustrates the locking key 41237 engaged with the distal ends 41516 of the arms 41512 at a distal end 41515 of the locking member 41510. As illustrated in Figure 157, the locking member 41510 has pivoted relative to - tion to the drive shaft 41100 about bosses 41513 (Figure

160) of the 41510 locking member to the unlocked configuration. When the locking member 41510 is in the unlocked configuration, the locking notch 41412 of the triggering drive shaft 41410 will release the locking boss 41511 of the locking member 41510 thus allowing the triggering member 41400 to move distally. through the 41230 staple cartridge. Referring to Figure 158, if the 41237 locking key is not present in the grip of the 41200 first jaw for the clamped configuration, then the 41510 locking member remains prone in the locked configuration through the clamping configuration. spring 41520 (Figure 159) pushing against tabs 41514 (Figure 160) of locking member 41510 where locking projection 41511 engages notch 41412 of firing drive shaft 41410 to block distal movement of the triggering member 41511. trigger 41400 beyond the initial distance used for the grip.

[0450] As discussed above, the surgical stapling assembly 41000 further comprises a direct access hole 41425 defined therein configured to allow a clinician to artificially move the locking member 41510 to the unlocked configuration. Hole 41425 may be positioned in any suitable component so that a tool 41590 can access locking member 41510 through hole 41425 to move locking member 41510 to the unlocked configuration. Hole 41425 is defined in channel cam portions 41424 of distal portion 41420 of firing member 41400. Hole 41425 may comprise access slots defined, for example, in channel cam portions 41424. In at least one example, the orifice 41425 is defined in drive shaft 41100 and/or a component thereof. However, locking member 41510 is directly accessible through hole 41425. Tool 41590 comprises a hook portion 41591 configured to be inserted through hole 41425 and an opening 41517 defined between arms 41512 of locking member 41510 for hooking, or latching onto an upper side of lug 41511 to pull lug 41511 and thereby pivoting locking member 41510 to the unlocked configuration overcoming the spring bias that encourages locking member 41510 to the locked configuration. The 41425 hole can be configured so that commonly avoidable tools, such as a screwdriver, for example, will not fit inside the hole, or external access opening, 41425. Portions of the 41510 locking member are illustrated in imaginary lines in the unlocked configuration in which tool 41590 has positioned locking member 41510 in the unlocked configuration. Arms 41512' and boss 41511' are imaginary line versions of arms 41512 and boss 41511 of locking member 41510 illustrated in the unlocked configuration.

[0451] After the 41510 locking member is manually or artificially overpowered to move the 41500 lock to the unlocked configuration, the 41400 triggering member is allowed to move distally beyond an unfired location and into the staple cartridge

41230. The untriggered location is defined as the position after it is locked in but before it is triggered. After the trigger member 41400 is advanced distally beyond its non-triggered position, the tool 41590 can be disengaged from the locking member 41510 and removed from the hole 41425 to allow the lock 41500 to resume normal operation. For example, the locking member 41510 will pivot to the locked configuration when the triggering member 41400 returns to the unfired location after having at least partially fired a staple cartridge. During the firing stroke, the locking member 41510 is accessible with the tool 41590 through a secondary access opening 41160 defined between a proximal end of the channel.

41210 and a distal end of the drive shaft 41100. That said, the locking member 41510 will continue to deactivate during the course of firing staples. In at least one case, the direct access hole is positioned within the drive shaft 41100, for example, and may provide access to the locking member 41510 during the firing stroke of the firing member 41400. In at least one case, secondary access opening 41160 comprises the locking primary access opening.

[0452] The 41500 lock can be positioned in any suitable location. In at least one example, the lock 41500 may be positioned proximal to the distal portion 41420 of the triggering member 41400 when the triggering member 41400 is in its most proximal position (as the position illustrated in Figure 159). In such a case, the access opening may be defined in a drive shaft cabinet, or frame, of the surgical stapling assembly 41000. In at least one case, the access opening is defined in channel 41210.

[0453] In at least one case, tool 41590 may be inserted through direct access opening 41425 to unlock lock 41500 prior to insertion of staple cartridge 41230 into channel 41210. Movement of lock 41500 to its unlocked configuration prior to Inserting a staple cartridge can assist with staple cartridge installation by preventing the 41500 latch from engaging the staple cartridge during installation. Some interlocks disable unsuitable staple cartridges by pushing a staple cartridge slider from its non-fired, triggerable position to a non-fired, non-fired position which can cause the staple cartridge to immediately become worn. Also, such jams can push a slider of a proper staple cartridge during installation of the proper staple cartridge. Unlocking the 41500 lock before installing the staple cartridge can ensure that the proper staple cartridge is not accidentally deactivated during installation.

[0454] Figures 161 and 162 depict a 42000 surgical staple set for use in tightening, stapling and cutting a patient's tissue. The 42000 Surgical Stapling Set is similar to other stapling sets described here in many respects. The surgical staple assembly 42000 comprises a trigger assembly 42100 and a cartridge channel 42200 configured to receive a staple cartridge therein. The 42100 Trigger Assembly is configured to push a slider of a suitable unspent staple cartridge installed in the 42200 cartridge channel to deploy the staple cartridge staples and cut the stapled fabric. The 42000 Surgical Staple Assembly additionally comprises a 42300 Lock configured to prevent the 42100 Trigger Assembly from being advanced through an inappropriate staple cartridge. Latch 42300 comprises a spring 42310 which biases latch 42300 towards a latched configuration. The 42300 lock is configured to be pushed proximally by an unspent staple cartridge suitable for unlocking the firing assembly

42100. In particular, the 42300 lock is configured so that the 42300 lock does not accidentally push the proper staple cartridge slider into a position that would induce a lock condition for the 42100 trigger assembly. The 42300 lock may use any method of proper locking. The 42100 trigger set is similar to other trigger sets described here.

[0455] The Surgical Staple Assembly 42000 further comprises a direct access cutout, or opening, 42210 defined in the bottom of the cartridge channel 42200 at a proximal end of a longitudinal slot 42230 defined in the cartridge channel

42200. Firing assembly 42100 is movable through slot 42230 of cartridge channel 42200 during a firing stroke of staples.

The 42210 Direct Access Cutout allows a tool to be inserted into the 42000 Surgical Staple Assembly to access the 42300 Lock directly.

The tool can be inserted through the direct access cutout 42210 to move the lock 42300 to an unlocked configuration (Figure 162). Unlocking the 42300 lock in this way can be called artificial unlocking the 42300 lock because an unused staple cartridge did not automatically unlock the 42300 lock for any reason.

Direct access cutout 42210 comprises a proximal end 42211 and a distal end 42213 which comprises a cutout portion wider than the proximal end 42211. The wider cutout portion of the distal end 42213 can aid in proper insertion of the tool into the channel. 42200. For example, the tool may comprise a latching engagement portion that engages the distal end 42213 but not the proximal end 42211 thus eliminating the possibility of incorrect insertion of the tool into the proximal end 42211. In addition, the latch 42300 , and its position in relation to other components of the Surgical Staple Assembly 42000, is also directly visible through the direct access cutout 42210. However, a tool can be inserted through the cutout 42210 to pull and /or push the 42300 lock proximally to overcome the spring bias and move the 42300 lock to the unlocked configuration.

The tool can also be removed and disengaged from the 42300 lock so that the 42300 lock can resume normal operation.

Additionally, providing the ability to manually move the 42300 Lock may allow a clinician to move the 42300 Lock away from its locked position prior to installing a staple cartridge in the 42200 cartridge channel to prevent the 42300 Lock from moving a cartridge slider. of staples being installed in the 42200 cartridge channel prematurely.

[0456] Figures 163 and 164 represent a surgical staple assembly 43000 comprising a trigger assembly 43100, a frame 43400 that supports the trigger assembly 43100 inside, a cartridge channel 43300 pivotally attached to the frame - ture 43400, and a key lock mechanism 43500 configured to override a lockout of the 43000 Surgical Staple Assembly. The 43000 Surgical Staple Assembly can comprise any suitable lock; however, a plunge knife lock where the 43100 firing assembly falls into a locking recess in the absence of a suitable unspent staple cartridge being positioned in the 43300 cartridge channel is described below.

[0457] The 43100 trigger assembly comprises a 43110 trigger drive shaft and a 43120 trigger member attached to the distal end of the 43110 trigger drive shaft. Although a linear trigger drive shaft is illustrated, the 43100 trigger assembly can be configured with a swivel drive shaft. The 43110 trigger drive shaft is configured to be actuated by a trigger trigger of a surgical instrument handle and/or a surgical robot, for example. Any suitable drive mechanism can be used. Firing member 43120 comprises anvil cam pins 43122 and channel cam pins 43123 extending laterally therefrom. Pins 43122, 43123 are configured to control the clamping pressure on the captured tissue in the 43000 Surgical Staple Assembly during a firing stroke. Firing member 43120 further comprises a cutting edge 43121 configured to cut trapped tissue. Firing member 43120 further comprises a protrusion, or distal nose, 43124 configured to engage and/or rest on top of a slider of a suitable unfired staple cartridge so that firing member 43120 does not fall into the recess. of locking.

[0458] The firing assembly 43100 further comprises an extension 43111 configured to be biased downwards towards the channel 43300 by a spring member mounted within the frame 43400. Discussed in more detail below, the downward bias of the extension 43111 encourages the 43100 trip assembly towards its latched condition. Downward bias is overcome when a suitable unspent staple cartridge is installed into the 43300 cartridge channel.

[0459] The key lock mechanism 43500 comprises a spring 43530, a wedge 43520 slidably supported within the frame 43400, and a lifting spring 43510 comprising a proximal end 43511 mounted to the frame 43400. The wedge 43520 comprises a ramp 43521 on which a distal end 43512 of the lifting spring 43510 rests. When a staple cartridge is inserted into the cartridge channel 43300, the staple cartridge 43200 pushes the wedge 43520 proximally. Proximal movement of wedge 43520 causes lifting spring 43510 to lift firing member 43120 to overcome a first stage of locking. Lifting spring 43510 comprises a notch 43513 defined in distal end 43512 configured to engage lifting pins 43125 extending laterally from firing member 43120 when lifting spring 43510 is lifted by wedge 43520 of staple cartridge 43200.

[0460] After the first stage of lockout is overcome, the 43100 trigger assembly is advanced distally to assess the second stage of lockout. This second phase of locking is overcome when the 43200 staple cartridge slider is in its proximal unfired position. Similar to the above, the 43110 trigger shaft can be lifted over the slider by the 43200 staple cartridge as the 43110 trigger shaft is advanced distally.

[0461] To cause the nose 43124 of the 43120 firing member to land on an unfired slider of the 43200 staple cartridge to overcome the second stage of locking and prevent the firing member 43120 from falling into the locking recess, a cartridge body 43211 is provided at a proximal end 43201 of cartridge body 43210. Now referring to Figure 164, as the 43200 staple cartridge is installed in the 43300 cartridge channel, the 43211 cartridge body key pushes the 43520 pro wedge - proximally and overcomes the spring bias provided by spring 43530. As wedge 43520 is pushed proximally, wedge 43520 lifts lift spring 43510. At this point, notch 43513 can hold lift pins 43125 and lift the assembly trigger

43100. Lifting the 43100 trigger assembly in this way can be called overcoming the first stage of the lock. In particular, a staple cartridge without the proper cartridge locking key may be able to install in the 43300 cartridge channel but will not be able to lift the 43100 firing assembly. After the 43200 staple cartridge is installed in the 43300 cartridge channel and the 43100 firing assembly is raised, the 43100 firing assembly can be advanced distally so that the 43513 notch can hold the 43100 firing assembly at the proper height and for the proper distance so that the 43124 nose can rest on the slider on the 43200 unfired staple cartridge thus preventing the locking recess. Resting the 43124 nose on the unfired slider can be called overriding the second stage of locking. If the switch

in the 43200 Staple Cartridge is not in its unfired position, the 43100 Firing Assembly will fall into the locking recess and will not be able to be advanced distally beyond its locked configuration. In at least one instance, the cartridge body key 43211 extends proximally from a cartridge body tray 43220 of the staple cartridge 43200.

[0462] Figure 165 depicts a first staple cartridge 43610 comprising a proximal end 43611 and a locking key 43613 extending from the proximal end 43611. Locking key 43613 comprises a first profile. Figure 165 depicts a second staple cartridge 43620 comprising a proximal end 43621 and a locking key 43623 extending from the proximal end 43621. Locking key 43623 comprises a second profile that is different from the first profile of locking key 43613 The first 43610 staple cartridge is configured to unlock only the stapling instruments it is compatible with, and the second 43620 staple cartridge is configured to unlock only the stapling instruments it is compatible with.

[0463] Again with reference to the 43500 key lock mechanism in Figures 163 and 164, cartridges that use different key profiles can be used to ensure that the firing member is lifted in the proper location and to the proper height. . Lifting the triggering member at different locations, with reference to Figure 165, causes different timings for lifting the triggering member. This can be used to ensure that an unsuitable staple cartridge cannot unlock a non-compatible instrument. Figures 166 and 167 contain graphs that illustrate the different lifting timings 43610', 43620' and displacements 43610'',

43620'' provided by the 43610, 43620 cartridges. The 43610 staple cartridge is configured to lift the triggering member before the 43620 staple cartridge. In a compatible surgical instrument, the first 43610 staple cartridge will cause a wedge, for example, like the wedge described in the present invention, to lift the firing member at the proper time and place so that the firing member will land on an unfired slider of the first staple cartridge 43610 so to overcome the lock and allow the firing member to be advanced distally to execute a staple firing stroke. In an incompatible surgical instrument, the first staple cartridge 43610 will cause a wedge, for example, to lift the triggering member at the wrong time and location causing the triggering member to fall off before hitting the slider or causing the trigger member pushes the slider distally before being lifted over the slider. Both situations involving the installation of an incompatible cartridge and instrument will cause the firing member to enter a locked condition after an attempt is made to move the firing member through a course of fire. The second 43620 staple cartridge functions similarly. That said, the second 43620 staple cartridge cannot unlock an instrument compatible with the first 43610 staple cartridge, and vice versa.

[0464] Figures 168 and 169 represent a 44000 system comprising a first cartridge 44100 (Figure 168) and a second cartridge 44200 (Figure 169). The first staple cartridge 44100 comprises a cartridge body 44110 comprising a proximal end 44111, a distal end 44112, and a plurality of staple cavities 44114 arranged in rows extending between the proximal end 44111 and the distal end

44112. The first staple cartridge 44100 additionally comprises a cartridge tray 44130 configured to hold the staples in the cartridge body 44110, a slider 44120 and configured to deploy the staples from the cartridge body 44110. anvil 44110 further comprises a longitudinal slot 44113 defined therein configured to receive a firing member of a surgical stapling instrument. Longitudinal slot 44113 defines a first side side and a second side side identified as "A" and "B" respectively. Cartridge body 44110 further comprises a locking key 44116 that extends from a proximal face 44115 of the first lateral side "A" of cartridge body 44110.

[0465] The second staple cartridge 44200 comprises a cartridge body 44210 comprising a proximal end 44211, a distal end 44212, and a plurality of staple cavities 44214 arranged in rows extending between the proximal end 44211 and the end 44212. The second staple cartridge 44200 further comprises a cartridge tray 44230 configured to contain staples in the cartridge body 44210, a slider 44220 and configured to deploy the staples from the cartridge body 44210. The anvil body 44210 it further comprises a longitudinal slot 44213 defined therein configured to receive a triggering member of a surgical stapling instrument. Longitudinal slot 44213 defines a first side side and a second side side identified as "A" and "B" respectively. Cartridge body 44210 further comprises a locking key 44216 extending from a proximal face 44215 of the second side side "B" of cartridge body 44210.

[0466] Clip cavities 44114 comprise three rows on each side of longitudinal slot 44113. Each row defines a row geometry with which each staple cavity in that row is aligned. In other words, the proximal end and distal end of each cavity in a single row are aligned with the row axis of that row. Clip cavities 44214 comprise three rows on each side of longitudinal slot 44213. Each row defines a row axis with which each staple cavity in that row is transversely aligned. Each side of the staple cartridge 44200 comprises an outer row of staple cavities 44214, an inner row of staple cavities 44214, and an intermediate row of staple cavities 44214 positioned between the outer row of staple cavities 44214 and the inner row of cavities of staples 44214. The staple cavities 44214 of the middle row define the cavity geometry axes that are transverse to the cavity axis by the staple cavities 44214 in the inner row and the staple cavities 44214 in the outer row.

[0467] The 44000 system provides a way to prevent an unsuitable staple cartridge from being used with a surgical stapling set by providing the locking keys for each cartridge on different sides of the staple cartridge. The provision of locking keys on different sides of the staple cartridge prevents the use of a stapling assembly comprising corresponding staple forming pockets for the first staple cartridge 44100 with the second staple cartridge 44200 and the use of a set of stapling comprising corresponding staple forming pockets for the second staple cartridge 44200 with the first staple cartridge 44100. Therefore, the first staple cartridge 44100 will not be able to unlock a trigger lock of a set of staples. surgical stapling intended for the second 44200 staple cartridge and the second 44200 staple cartridge will not be able to unlock a trigger lock of a surgical stapling assembly intended for the first staple cartridge

44100. This prevents improper cartridge installation, which can result in staples deploying against an anvil with mismatched staple forming pockets.

[0468] Figures 170 to 179 depict a 45000 surgical staple set configured to clamp, staple, and cut a patient's tissue. The 45000 Surgical Stapling Set can be used with a surgical robot and/or a surgical instrument handle. The surgical stapling assembly 45000 comprises a first jaw 45200, a second jaw 45400 movable with respect to the first jaw 45200 between an unclamped configuration and a clamped configuration, and a triggering assembly 45500. The surgical stapling assembly 45000 additionally comprises a replaceable staple cartridge 45300 comprising a plurality of staples removable stored therein that are configured to be deployed by the firing assembly 45500. The first jaw 45200 comprises a channel 45210 configured to receive the replaceable staple cartridge 45300. The second jaw 45400 comprises an anvil 45410 which comprises a staple forming surface 45415 configured to form the staples implanted from the staple cartridge 45300. The first jaw 45200 additionally comprises pin openings 45212 ( Figure 171) in which the pivot pins 45413 of the second jaw 45400 are received to allow the second jaw 45400 pivots with respect to the first jaw 45200. Arrangements are envisaged in which the fixed jaw comprises the anvil and the movable jaw comprises the channel and the staple cartridge.

[0469] To secure tissue with the surgical stapling assembly 45000, the second jaw 45400 comprises a cam surface 45412 formed at a proximal end 45411 thereof which is configured to be engaged by a closure member. The closure member comprises a closure tube, for example, but may comprise any other suitable configuration. The closing member is configured to move the second jaw 45400 from the loose configuration to the clamped configuration towards the channel 45210 by engaging and sliding along the cam surface 45412. To release the 45000 Surgical Staple Assembly, the closing member is retracted proximally. A spring may be provided to bias the second jaw 45400 into the loose configuration as the closing member disengages cam surface 45412.

[0470] To staple and cut tissue with the 45000 Surgical Stapling Set, a suitable unspent staple cartridge needs to be installed inside the Surgical Stapling Set

45000. When a suitable unspent staple cartridge is installed into the 45210 channel, the 45500 trigger assembly can be actuated through the 45300 staple cartridge to push a 45340 slider of the 45300 staple cartridge distally from a position non-fired to a fired position to deploy staples stored within the 45300 staple cartridge during a staple firing stroke. As the firing assembly 45500 moves through the firing course of staples, a cutting edge 45523 of the firing assembly cuts the tissue trapped between the first jaw 45200 and the second jaw 45400. In at least one case, the cutting edge 45523 follows behind the staple implantation to prevent the tissue from being cut before the tissue is stapled.

[0471] Referring primarily to Figures 172 to 175, the firing assembly 45500 comprises a firing member 45520 comprising cutting edge 45523, anvil cam portions

45521 and channel cam portions 45522 configured to control the distance between the first jaw 45200 and the second jaw 45400 during the firing stroke of staples, and laterally extending portions 45525 positioned between the anvil cam portions 45521 and channel cam portions 45522 configured to fall into a lock, as discussed in more detail below. The trigger member 45520 further comprises a tail 45526 extending proximally therefrom which is configured to interface with a spring 45240 mounted on the drive shaft as discussed in greater detail below.

[0472] To prevent the 45500 firing assembly from being advanced through an inadequate and/or worn staple cartridge, the 45000 surgical stapling assembly additionally comprises a locking system. The 45000 surgical stapling assembly comprises a diving knife lock like that disclosed herein wherein the 45500 trigger assembly falls into a locking pocket if a suitable unused staple cartridge is not installed within the 45000 surgical stapling assembly. A suitable unspent staple cartridge, such as the 45300 staple cartridge, is configured to prevent the 45500 firing assembly from falling into the locking pocket by lifting the 45500 firing assembly when the 45300 staple cartridge is not depleted. In such cases, a distal end of the trigger assembly will land on an unfired slider of the 45300 staple cartridge. The 45500 trigger assembly can then be advanced through the 45300 staple cartridge.

[0473] The 45300 Staple Cartridge includes a 45330 Locking Key to lift the 45500 Firing Assembly to the proper height and distance to allow the 45500 Firing Assembly to land on an unfired slider and override the lock. of the surgical staple assembly 45000. The staple cartridge 45300 further comprises a cartridge body 45310 comprising a proximal end 45301 comprising a proximal face 45313 and a longitudinal slot 45311 configured to receive the firing assembly 45500 during staple firing course. Locking key 45330 extends proximally from proximal face 45313 of cartridge body 45310 and comprises a pair of protuberances that define a proximal longitudinal slot portion 45333 of longitudinal slot 45311. The proximal longitudinal slot portion 45333 is configured to engage firing member 45520 when staple cartridge 45300 is installed in channel 45210. Each protrusion of locking key 45330 comprises an inclined surface, or portion, 45331 and an uninclined portion, or surface, 45332. The 45300 staple cartridge further comprises a tray 45320 configured to hold the staples in the 45310 cartridge body. The 45320 tray is configured to clamp over a platform 45312 of the 45310 cartridge body. cartridge 45310 by a series of hooks 45321 that are formed in the side walls 45320 and configured to engage hook-and-loop by corresponding parts of the 45310 cartridge body. In at least one case, the tray may comprise the locking key.

[0474] The 45500 Firing Assembly comprises a 45510 Firing Drive Shaft configured to transfer firing motions to the 45520 Firing Member. The 45520 Firing Member is attached to a Distal End 45513 of the Firing Drive Shaft.

45510. Firing member 45520 is biased downward by spring 45420 mounted on drive shaft. More specifically, the spring 45420 pushes the tail 45526 of the firing member 45520 downwards to bias the firing member 45520 unless the firing member 45520 is lifted upwards in the opposite direction to the firing latch. To lift the trigger assembly 45500, the surgical clip assembly 45000 comprises a floating pin 45600 positioned behind the trigger member 45520 of the trigger assembly

45500. The floating pin 45600 is supported within a slot, or channel, 45213 defined on the sides of the staple cartridge channel 45210. The floating pin 45600 is configured to move vertically within the slot 45213 by the inclined surfaces 45331. More specifically, the floating pin 45600 is pushed upward by locking key 45330 into staple cartridge channel 45210 which in turn contacts the bottom edge of firing member 45520 and pushes firing member 45520 upwards. In this way, the 45600 floating pin does not allow the 45520 trigger member to plunge into the trigger lock when the 45300 staple cartridge is seated in the 45210 staple cartridge channel. As such, the 45330 locking key overrides the 45330 staple cartridge channel. spring-down bias applied to firing member 45520 by spring 45240.

[0475] After the 45300 staple cartridge is fully installed and the 45500 trigger assembly is raised to the position illustrated in Figure 174, the 45500 trigger assembly can then be advanced distally towards the staple cartridge slider 45340

45300. In this way, with the proper locking switch, the first stage of locking is overridden. If the slider 45340 is in its non-triggered position, a distal nose, or shelf, 45524 of the triggering member 45520 will land on a corresponding platform 45341 of the slider 45340 and avoid the locking discussed above. The landing of the distal nose 45524 of the firing member 45520 on the platform 45341 of the slider 45340, when the slider 45340 is in its unfired position, overcomes a second stage of the lock. As the 45500 trigger assembly is advanced distally, the bottom surface 45511 moves along the 45600 floating pin and the float height of the 45500 trigger assembly is governed by the engagement between the 45600 floating pin, the bottom surface 45511 of the 45510 trigger shaft, and the 45600 locking key.

[0476] Due to the fact that the height of the 45500 trigger assembly is regulated by the engagement between the 45600 floating pin, the 45511 bottom surface of the 45510 trigger shaft and the 45600 locking key, the trigger shaft 45511 45510 is configured so that the 45500 trigger assembly can still fall into the lock when the 45340 slider on the 45300 staple cartridge is not in its unfired position. Referring to Figures 176 and 177, the bottom surface 45511 comprises a notch 45515 defined proximal to the distal end 45513 of the trigger drive shaft 45510. The notch 45515 is configured so that the trigger drive shaft 45510 falls into the lockout if slider 45340 is not present in its untriggered position. Figure 176 illustrates staple cartridge 45300 installed within channel 45210; however, slider 45340 is not present in its unfired position. Thus, turning to Figure 177, the trigger drive shaft 45510 is not lifted sufficiently up by the floating pin 45600 to lift the trigger drive shaft 45510 out of the lock. Instead, the 45510 firing drive shaft is pulled down by the 45240 spring when the 45500 firing assembly is advanced distally because the 45600 floating pin fits into the 45515 notch. needs to be removed and replaced with a proper unfired staple cartridge.

[0477] If a staple cartridge is installed in a surgical stapling assembly that does not have a proper locking key, the 45600 floating pin will remain in its lowest position illustrated in Figure 172. If an attempt is made to advance the 45500 trigger assembly distally, the 45500 trigger assembly will not be able to overcome the first stage of lockout.

[0478] Figure 180 represents the 45300 staple cartridge discussed above. Figure 181 depicts a second staple cartridge 45900 comprising a cartridge body 45910 and a tray 45920 configured to hold a plurality of staples in the staple cartridge 45900. Cartridge body 45910 further comprises a locking key 45930 that engages extends proximally from a proximal face 45913 of cartridge body 45910. As can be seen from Figures 180 and 181, staple cartridge 45300 and second staple cartridge 45900 comprise similar features; however, they comprise locking switches that have different settings. The locking key 45330 of the staple cartridge 45300 comprises a first length 45338 and a first height 45339 while the locking key 45930 of the second staple cartridge 45900 comprises a second length 45938 and a second height 45939 which are different from the first length 45338 and first height 45339, respectively. The 45300, 45900 staple cartridges are part of a system in which the 45300 staple cartridge can only unlock a first instrument but not a second instrument while the 45900 second staple cartridge can only unlock the second instrument and not the second instrument. first instrument. The locking key 45930 comprises an inclined surface 45931 and a flat surface 45932 which have different dimensions from the surfaces 45331, 45332 of the locking key 45330. The locking key 45330 of the staple cartridge 45300 is shown in imaginary lines in the Figure 181 for comparison purposes.

[0479] Different locking switch settings between similar looking cartridges, for example, can prevent a clinician from inserting and using an incompatible cartridge in a second instrument. In this case, the 45330, 45930 interlock switches will cause an instrument trigger set to rise to different heights and at different times during the triggering course of the trigger set. Referring again to the 45600 floating pin, if the second 45900 staple cartridge is installed in the 45000 surgical stapling assembly, the 45500 firing assembly will be lifted by the 45600 floating pin to a height that is less than a height at which the 45600 assembly trigger 45500 will be lifted by floating pin 45600 if staple cartridge 45300 is installed. This will result in the 45500 firing assembly not being able to land on the platform of the second staple cartridge's platform glider and will instead become locked. This will avoid using an unsuitable staple cartridge inside a stapling instrument.

[0480] The instrument with which the second staple cartridge 45900 can be used may comprise a similar floating pin system as discussed above; however, this float pin may be located in a different position to the second 45900 staple cartridge so that the 45930 locking key can lift the triggering member of this instrument to the proper height and time for land on the slider of the second 45900 staple cartridge to bypass the instrument lock. In at least one case, the locking keys described herein comprise cartridge body fins, for example.
