FIGS. 1 to 4 show a motor driven surgical cutting and fastening instrument 10 that may or may not be reused. In the illustrated embodiment, the instrument 10 includes a housing 12 with a handle 14 configured to be grasped, operated and actuated by a clinician. The housing 12 is operably attached to an elongated shaft assembly 200 to which a surgical end effector 300 configured to perform one or more surgical tasks or procedures is operably coupled. It is configured. The elongated shaft assembly 200 is disclosed, for example, in U.S. Patent Application No. 14 / 226,075, the title of the invention "MODULAR POWERED SURGICAL INSTRUMENT WITH DETACHABLE SHAFT ASSEMBLES," the entire disclosure of which is incorporated herein by reference. It can be interchangeable with other shaft assemblies in various ways. In other embodiments, the elongated shaft assembly may not be replaceable with other shaft assemblies and may essentially include a dedicated non-detachable portion of the appliance.

As you read through the embodiments for practicing the present invention, it is understood that the various forms of interchangeable shaft assemblies disclosed herein can also be effectively used in connection with robotic surgical systems. Will be done. Therefore, the term "housing" is also configured to generate and apply at least one control motion that can be used to actuate the elongated shaft assemblies and their respective equivalents disclosed herein. It may also include a housing or similar portion of the robot system that accommodates at least one drive system or otherwise operably supports it. The term "frame" may refer to a portion of a handheld surgical instrument. The term "frame" may also refer to a portion of a robot-controlled surgical instrument and / or a portion of a robotic system that may be used to operably control the surgical instrument. For example, the shaft assemblies disclosed herein are incorporated herein by reference in their entirety, U.S. Patent Application No. 13/118241, the title of the invention "SURGICAL STAPLING INSTRUMENTS WITH ROTATABLE STAPLE DEPLOYMENT ARRANGEMENTS", present in the United States. It can be used with various robot systems, instruments, components, and methods disclosed in Patent Application Publication No. 2012/02987719.

The housing 12 shown in FIG. 1 is shown with an elongated shaft assembly 200 that includes an end effector 300 with a surgical cutting and fastening device configured to operably support the surgical staple cartridge 304 inside. There is. The housing 12 includes end effectors adapted to support staple cartridges of various sizes and types and is configured for use in association with shaft assemblies having various shaft lengths, sizes, types and the like. May be done. In addition, the housing 12 is also adapted to use other motion and morphological energies such as radio frequency (RF) energy, ultrasonic energy and / or motion in connection with various surgical applications and procedures. It may be effectively used with a variety of other shaft assemblies, including assemblies configured to apply to the end effector configuration. In addition, end effectors, shaft assemblies, handles, surgical instruments, and / or surgical instrument systems can be used to fasten tissue using any suitable fastener. For example, a fastener cartridge with a plurality of fasteners retractably housed therein can be detachably inserted and / or mounted on an end effector of a shaft assembly.

FIG. 1 shows a housing 12 or handle 14 of a surgical instrument 10 to which a replaceable elongated shaft assembly 200 is operably coupled. As can be seen in FIG. 1, the handle 14 may include a pair of interconnectable handle housing segments 16 and 18 that may be interconnected with screws, snap mechanisms, adhesives and the like. In the illustrated configuration, the handle housing segments 16 and 18 work together to form a pistol grip portion 19 that can be gripped and manipulated by the clinician. As described in more detail below, the handle 14 operably supports a plurality of drive systems internally, which are operably attached to the corresponding portion of the replaceable shaft assembly. On the other hand, it is configured to generate and add various control motions.

With reference to FIG. 2, the handle 14 may further include a frame 20 that operably supports a plurality of drive systems. For example, the frame 20 can operably support a "first" or closed drive system, represented by 30 as a whole, the closed drive system operably mounted or coupled therein. It can be used to add closing and opening motion to the shaft assembly 200. In at least one embodiment, the closure drive system 30 may include an actuator in the form of a closure trigger 32 pivotally supported by the frame 20. More specifically, as shown in FIG. 2, the closure trigger 32 is pivotally coupled to the housing 14 by a pin 33. Such an arrangement allows the clinician to operate the closure trigger 32 so that when the clinician grips the pistol grip portion 19 of the handle 14, the closure trigger 32 is moved from the starting position or the "inactive" position. It can be easily pivoted to the "actuated" position, more specifically to the fully compressed or fully actuated position. The closing trigger 32 may be urged to a non-actuated position by a spring or other urging device (not shown). In various forms, the closure drive system 30 further includes a closure linkage assembly 34 pivotally coupled to the closure trigger 32. As can be seen in FIG. 2, the closure link mechanism assembly 34 may include a first closure link 36 and a second closure link 38 that are pivotally coupled to the closure trigger 32 by a pin 35. The second closing link 38, sometimes referred to herein as a "mounting member," includes a transverse mounting pin 37.

Continuing with reference to FIG. 2, the first closure link 36 has a locking wall or end 39 on it configured to cooperate with an unlocking assembly 60 pivotally coupled to the frame 20. You can observe what you may do. In at least one form, the release release assembly 60 may include a release button assembly 62 on which a locking claw 64 projecting distally is formed. The release button assembly 62 may be pivoted counterclockwise by a release spring (not shown). When the clinician pushes the closure trigger 32 from its non-actuated position towards the pistol grip portion 19 of the handle 14, the lock claw 64 heads towards the point where the lock claw 64 reaches the retention engagement with the lock wall 39 on the first closure link 36. The first closing link 36 is pivoted upwards, thereby preventing the closing trigger 32 from returning to the inactive position. Therefore, the closure release assembly 60 acts to lock the closure trigger 32 in the fully actuated position. If the clinician wants to unlock the closure trigger 32 so that it can be urged to the inactive position, the clinician simply pivots the unlock button assembly 62 and thereby locks it. The claw 64 is moved to disengage from engagement with the lock wall 39 on the first closing link 36. When the lock claw 64 is moved to disengage from engagement with the first closing link 36, the closing trigger 32 may pivot and return to the inactive position. Other closed trigger lock and release configurations may be used.

When the closing trigger 32 is moved from the non-working position to the working position, the closing release button 62 is pivoted between the first position and the second position. The rotation of the release button 62 can be referred to as an upward rotation, but at least a portion of the release button 62 is rotated towards the circuit board 100. Still referring to FIG. 2, the closure release button 62 can include an arm 61 extending from it and a magnetic element 63 mounted on the arm 61, such as a permanent magnet. When the closure release button 62 is rotated from its first position to its second position, the magnetic element 63 can move toward the circuit board 100. The circuit board 100 may include at least one sensor configured to detect the movement of the magnetic element 63. In at least one embodiment, a "Hall effect" sensor may be mounted on the bottom surface of the circuit board 100. The Hall effect sensor may be configured to detect changes in the magnetic field surrounding the Hall effect sensor caused by the movement of the magnetic element 63. The Hall effect sensor is capable of signal communication with, for example, a microcontroller, whereby the release release button 62 is in the first position associated with the non-actuated position of the closure trigger 32 and the open configuration of the end effector. Or is it in a second position associated with the actuation position of the closure trigger 32 and the closure configuration of the end effector, and / or in any position between the first and second positions. Can be judged.

Also in the illustrated configuration, the handle 14 and frame 20 are configured to apply firing motion to the corresponding portion of the attached interchangeable shaft assembly, another drive system referred to herein as the firing drive system 80. Supports operability. The launch drive system 80 is also sometimes referred to herein as a "second drive system." The launch drive system 80 may use an electric motor 82 located within the pistol grip portion 19 of the handle 14. In various forms, the motor 82 may be, for example, a brushed DC drive motor having a maximum rotation speed of about 25,000 RPM. In other configurations, the motor may include a brushless motor, a cordless motor, a synchronous motor, a stepper motor, or any other suitable electric motor. The motor 82 may include a removable power pack 92 in one form, or may be powered by a power source 90. For example, as can be seen in FIG. 2, the power pack 92 may include a proximal housing portion 94 configured for attachment to the distal housing portion 96. The proximal housing portion 94 and the distal housing portion 96 are configured to operably support a plurality of batteries 98 therein. Each of the batteries 98 may include, for example, lithium ion (“LI”) or other suitable battery. The distal housing portion 96 is configured to be detachably and operably attached to the control circuit board assembly 100, which is also operably coupled to the motor 82. A large number of batteries 98, which may be connected in series, may be used as a power source for the surgical instrument 10. In addition, the power supply 90 may be replaceable and / or rechargeable.

As outlined above in relation to various other forms, the electric motor 82 is a gear reducer assembly mounted by engaging and engaging a set of drive teeth 122 or racks on a longitudinally movable drive member 120. Includes a rotary shaft (not shown) that operably interfaces with the 84. In use, the voltage polarity provided by the power supply 90 can cause the electric motor 82 to operate clockwise, but the voltage polarity applied to the electric motor by the battery causes the electric motor 82 to operate counterclockwise. Can be inverted to. When the electric motor 82 is rotated in a certain direction, the drive member 120 is axially driven in the distal direction "DD". When the motor 82 is driven in the opposite rotational direction, the drive member 120 is axially driven in the proximal direction "PD". The handle 14 may include a switch that can be configured to reverse the polarity applied to the electric motor 82 by the power supply 90. Similar to other embodiments described herein, the handle 14 also includes a sensor configured to detect the position of the drive member 120 and / or the direction in which the drive member 120 is being moved. Can be done.

The operation of the motor 82 is controlled by a firing trigger 130 pivotally supported on the handle 14. The firing trigger 130 may be pivoted between the non-actuated position and the actuated position. The firing trigger 130 may be urged to a non-actuated position by a spring 132 or other urging device, whereby when the clinician releases the firing trigger 130, it is not urged by the spring 132 or other urging device. It may be pivoted to the working position or returned in another way. In at least one form, the firing trigger 130 can be positioned "outside" the closing trigger 32, as described above. In at least one embodiment, the firing trigger safety button 134 may be pivotally attached to the closing trigger 32 by a pin 35. The safety button 134 may have a pivot arm 136 that is positioned between the firing trigger 130 and the closing trigger 32 and projects from it. See FIG. When the closing trigger 32 is in the non-actuated position, the safety button 134 is housed in the handle 14 and is not easily accessible to the clinician, with a safety position to prevent the firing trigger 130 from operating and the firing trigger 130. It cannot be moved to or from a firing position where it may be fired. When the clinician presses the closure trigger 32, the safety button 134 and the firing trigger 130 are pivoted down, which in turn allows the clinician to operate them.

As mentioned above, the handle 14 includes a closing trigger 32 and a firing trigger 130. The firing trigger 130 may be pivotally mounted on the closing trigger 32. When the closing trigger 32 is moved from its non-actuated position to the activated position, the firing trigger 130 can descend downward as described above. After the safety button 134 has been moved to its launch position, the launch trigger 130 may be pressed to activate the motor of the surgical instrument launch system. In various examples, the handle 14 may include a tracking system configured to determine the position of the closing trigger 32 and / or the position of the firing trigger 130.

As shown above, in at least one embodiment, the longitudinal movable drive member 120 is a rack of drive teeth 122 formed on the longitudinal movable drive member 120 to mesh and engage with the corresponding drive gear 86 of the gear reducer assembly 84. Has. At least one form is also a manually actuated "emergency" configured to allow the clinician to manually retract the longitudinally movable drive member 120 if the motor 82 becomes unusable. Includes "disengagement" assembly 140. The emergency disengagement assembly 140 may include a lever or emergency disengagement handle assembly 142 that is manually pivoted to ratchet engage with the teeth 124 also provided on the drive member 120. Therefore, the clinician can manually drive the drive member 120 by ratcheting the drive member 120 in the proximal direction "PD" using the emergency withdrawal handle assembly 142. U.S. Patent Application Publication No. 2010/0899970 discloses an emergency withdrawal device, as well as other components, configurations, and systems that can also be used with the various instruments disclosed herein. U.S. Patent Application No. 12 / 249,117, title of invention "POWERED SURGICAL CUTTING AND STAPLING APPARATUS WITH MANUALLY RETRACTABLE FIRING SYSTEM", see current U.S. Pat. No. 8,608,045, in its entirety. Be incorporated.

Next, referring to FIGS. 1 and 3, the elongated shaft assembly 200 includes a surgical end effector 300 with an elongated channel 302 configured to operably support the staple cartridge 304 inside. The end effector 300 may further include an anvil 310 that is pivotally supported with respect to the elongated channel 302. As discussed in more detail below, the surgical end effector 300 may be articulated with respect to the elongated shaft assembly around the articulation joint 270. As can be seen in FIGS. 3 and 4, the shaft assembly 200 may further include a proximal housing or nozzle 201 consisting of nozzle portions 202 and 203. The shaft assembly 200 further includes a closing tube 260 that can be used to close and / or open the anvil 310 of the end effector 300. As can be seen in FIG. 4, the shaft assembly 200 includes a spine 210 that may be configured to fixably support the shaft frame portion 212 of the joint lock 350. U.S. Patent Application No. 13 / 803,086, the title of the invention "ARTICULATABLE SURGICAL INSTRUMENT COMPRISING AN ARTICULATION LOCK", which details of the configuration and operation of the joint lock 350 are incorporated herein by reference in its entirety. It is described in the current US Patent Application Publication No. 2014/0263541. The spine 210 is configured to slidably support the launching member 220 therein, and to slidably support the closing tube 260 extending around the spine 210. The spine 210 also slidably supports the proximal joint driver 230. The proximal joint driver 230 has a distal end 231 configured to operably engage the joint lock 350. In one configuration, the joint lock 350 interfaces with a joint frame 352 adapted to operably engage a drive pin (not shown) on an end effector frame (not shown).

In the illustrated configuration, the spine 210 comprises a proximal end 211 rotatably supported within the chassis 240. In one configuration, for example, a thread 214 is formed at the proximal end 211 of the spine 210 so that it is screwed into a spine bearing 216 configured to be supported within the chassis 240. See FIG. Such a configuration facilitates the rotatable attachment of the spine 210 to the chassis 240 so that the spine 210 can be selectively rotated about the shaft axis SA-SA with respect to the chassis 240. The shaft assembly 200 also includes a closure shuttle 250 slidably supported therein so that it can be moved axially with respect to the chassis 240. As can be seen in FIG. 3, the closure shuttle 250 includes a pair of proximal protruding hooks 252, which are mounting pins mounted on the second closing link 38, as discussed in more detail below. It is configured to be attached to 37. See FIG. The proximal end 261 of the closure tube 260 is coupled to the closure shuttle 250 so that it rotates relative to each other. For example, the U-connector 263 is inserted into an annular slot 262 at the proximal end 261 of the closure tube 260 and retained in the vertical slot 253 of the closure shuttle 250. See FIG. Such a configuration serves to attach the closing tube 260 to it so as to move axially with the closing shuttle 250, while allowing the closing tube 260 to rotate relative to the closing shuttle 250 about the shaft axis SA-SA. To. The closing spring 268 is pivotally supported on the closing tube 260 and serves to urge the closing tube 260 in the proximal direction "PD", whereby the shaft assembly 200 is operably coupled to the handle 14. It can play a role in pivoting the closure trigger to the inactive position.

As also mentioned above, the elongated shaft assembly 200 further includes a launching member 220 that is supported to move axially within the shaft spine 210. The launch member 220 includes an intermediate launch shaft portion 222 configured to be mounted on a distal cut portion or launch beam 280. The launching member 220 may also be referred to herein as a "second shaft" and / or a "second shaft assembly". As can be seen in FIG. 4, the intermediate launch shaft portion 222 may include a longitudinal slot 223 at its distal end, which is a tab 284 on the proximal end 282 of the distal launch beam 280. Can be configured to accept. The longitudinal slot 223 and the proximal end 282 can be sized and configured to allow relative movement between them and can include a slip joint 286. The slip joint 286 moves the intermediate firing shaft portion 222 of the firing drive 220 to jointly move the surgical end effector 300 without moving the firing beam 280, or at least substantially. It can be possible. When the surgical end effector 300 is suitably oriented, the proximal side wall of the longitudinal slot 223 contacts the tab 284 to advance the firing beam 280 and launch a staple cartridge that can be supported within the end effector 300. Until then, the intermediate launch shaft portion 222 can be advanced distally. Further, as can be seen in FIG. 4, the shaft spine 210 has an elongated opening or window 213 to facilitate assembly and insertion of the intermediate launch shaft portion 222 into the shaft frame 210. When the intermediate launch shaft portion 222 is inserted into the shaft frame 210, the top frame split portion 215 can be engaged with the shaft frame 212 to enclose the intermediate launch shaft portion 222 and the launch beam 280 therein. Further statements regarding the operation of the launching member 220 can be found in US Patent Application No. 13 / 803,086, and current US Patent Application Publication No. 2014/0263541.

In addition to the above, the illustrated shaft assembly 200 includes a clutch assembly 400 that may be configured to selectively and releasably couple the joint driver 230 to the launch member 220. In one embodiment, the clutch assembly 400 includes a lock collar, i.e. a sleeve 402, that is positioned around the launch member 220, where the lock sleeve 402 is in an engaging position where the lock sleeve 402 couples the joint driver 360 to the launch member 220. And the joint driver 360 can be rotated between the disengagement position, which is not operably coupled to the launching member 200. When the lock sleeve 402 is in its engaged position, the launch member 220 can be moved distally to move the joint driver 360 distally, correspondingly proximal to the launch member 220. The directional movement allows the proximal joint driver 230 to be moved proximally. When the lock sleeve 402 is in its disengaged position, the movement of the launching member 220 is not transmitted to the proximal joint driver 230, so that the launching member 220 moves independently of the proximal joint driver 230. be able to. Under various circumstances, the proximal joint driver 230 may be held in place by the joint lock 350 when the proximal joint driver 230 has not been moved proximally or distally by the launching member 220.

Further, as can be seen from FIG. 4, the lock sleeve 402 may comprise a cylindrical or at least substantially cylindrical body in which a longitudinal aperture 403 configured to receive the launching member 220 is defined. .. The lock sleeve 402 may include a locking projection 404 facing inward and a locking member 406 facing outward facing in the radial direction. The lock projection 404 can be configured to selectively engage the launching member 220. More specifically, when the lock sleeve 402 is in its engaging position, the lock protrusion 404 is positioned within a drive notch 224 defined in the launching member 220, thereby causing a distal push and / or proximal. The tensile force can be transmitted from the launching member 220 to the lock sleeve 402. When the lock sleeve 402 is in its engaging position, the second locking member 406 is received within the drive notch 230 defined in the proximal joint driver 232, thereby exerting a distal push force on the lock sleeve 402. And / or proximal tensile force may be transmitted to the proximal joint driver 230. In essence, the launch member 220, the lock sleeve 402, and the proximal joint driver 230 will move with each other when the lock sleeve 402 is in its engaging position. On the other hand, when the lock sleeve 402 is in its disengaged position, the lock protrusion 404 may not be positioned within the drive notch 224 of the launching member 220, resulting in a distal push and / or proximal tensile force. May not be transmitted from the launching member 220 to the lock sleeve 402. Accordingly, the distal pushing force and / or the proximal tensile force need not be transmitted to the proximal joint driver 230. In such a situation, the launching member 220 can be slid proximally and / or distally to the lock sleeve 402 and the proximal joint driver 230.

As can be seen from FIG. 4, the elongated shaft assembly 200 further includes a switch drum 500 that is rotatably received on the closed tube 260. The switch drum 500 includes a hollow shaft segment 502 in which a shaft boss 504 that receives an outwardly projecting actuating pin 410 is formed. In various situations, the actuating pin 410 extends through slot 267 into the longitudinal slot 408 provided in the lock sleeve 402 when the lock sleeve 402 is engaged with the proximal joint driver 230. To facilitate its axial movement. The rotary torsion spring 420 is configured to engage a shaft boss 504 on the switch drum 500 and a portion of the nozzle housing 203 to apply urging force to the switch drum 500. The switch drum 500 may further include, at least partially, a circumferential opening 506 defined therein, the opening extending from nozzle portions 202, 203, with reference to FIGS. 5 and 6. It may be configured to accept the circumferential mounts 204, 205 to allow relative rotation between the switch drum 500 and the proximal nozzle 201, but not translation. The mount also extends through the opening 266 of the closing tube 260 and is seated in the recess n of the shaft spine 210. However, if the nozzle 201 is rotated to the point where the mount reaches the end of the corresponding slot 506 in the switch drum 500, the switch drum 500 will rotate about the shaft axis SA-SA. When the switch drum 500 rotates, the actuating pin 410 and the lock sleeve 402 will eventually rotate between their engaging and disengaging positions. Thus, in essence, Nozzle 201 is a joint drive system and launch in a variety of manners described in more detail in U.S. Patent Application No. 13 / 803,086 and current U.S. Patent Application Publication No. 2014/0263541. It may be used to operably engage and disengage with the drive system.

As also shown in FIGS. 3 and 4, the elongated shaft assembly 200 conducts power to and / or from the end effector 300 and / or signals to and / or from the end effector 300. It may include a slip ring assembly 600 that may be configured to communicate. The slip ring assembly 600 includes a proximal connector flange 604 mounted on a chassis flange 242 extending from the chassis 240 and a distal connector flange 601 located in a slot defined in shaft housings 202, 203. Can be done. The proximal connector flange 604 may comprise a first surface and the distal connector flange 601 may comprise a second surface that is positioned adjacent to and movable relative to the first surface. it can. The distal connector flange 601 can rotate about the shaft axis SA-SA with respect to the proximal connector flange 604. The proximal connector flange 604 can include a plurality of concentric, or at least substantially concentric, conductors 602 defined on its first surface. The connector 607 can be mounted on the proximal surface of the distal connector flange 601 and may have multiple contacts (not shown), each contact corresponding to and with one of the conductors 602. Make electrical contact. Such a configuration allows the proximal connector flange 604 and the distal connector flange 601 to rotate relative to each other while maintaining electrical contact between them. The proximal connector flange 604 can include, for example, an electrical connector 606 capable of arranging a conductor 602 in signal communication with a shaft circuit board 610 mounted on the shaft chassis 240. In at least one example, a wiring harness with a plurality of conductors can extend between the electrical connector 606 and the shaft circuit board 610. The electrical connector 606 may extend proximally through the connector opening 243 defined in the chassis mounting flange 242. See FIG. 7.

The entire contents of US Patent Application No. 13 / 800,025 filed on March 13, 2013, the title of the invention "STAPLE CARTRIDGE TISSUE THICKNESS SENSOR SYSTEM", and the current US Patent Application Publication No. 2014/0263551 Incorporated herein by reference.

As described above, the elongated shaft assembly 200 can include a proximal portion that is fixably mounted to the handle 14 and a distal portion that is rotatable about the longitudinal shaft axis SA-SA. The rotatable distal shaft portion can be rotated with respect to the proximal portion about the slip ring assembly 600, as described above. The distal connector flange 601 of the slip ring assembly 600 can be positioned within a rotatable distal shaft portion. In addition to the above, the switch drum 500 can also be positioned within the rotatable distal shaft portion. Rotating the rotatable distal shaft portion allows the distal connector flange 601 and the switch drum 500 to rotate synchronously with each other. In addition, the switch drum 500 can be rotated between the first and second positions with respect to the distal connector flange 601. When the switch drum 500 is in its first position, the joint drive system (ie, the proximal joint driver 230) can be operably disengaged from the launch drive system, thus the operation of the launch drive system is shaft. The end effector 300 of the assembly 200 cannot be articulated. When the switch drum 500 is in its second position, the joint drive system (ie, the proximal joint driver 230) can be operably engaged with the launch drive system, thus the operation of the launch drive system is the shaft assembly. 200 end effectors 300 can be articulated. When the switch drum 500 is moved between its first and second positions, the switch drum 500 is moved relative to the distal connector flange 601. In various examples, the shaft assembly 200 may include at least one sensor configured to detect the position of the switch drum 500.

With reference to FIG. 4 again, the closure tube assembly 260 includes a double pivot closure sleeve assembly 271. According to various forms, the double pivot closure sleeve assembly 271 includes an end effector closure sleeve 272 that includes upper and lower distal protruding tongues 273 and 274. The upper double pivot link 277 projects upward, engaging the upper distal pinhole of the upper proximal protruding tongue 273 and the upper proximal pinhole of the upper distal protruding tongue 264, respectively, on the closure tube 260. Includes distal and proximal pivot pins. The lower dual pivot link 278 engages the lower distal pinhole of the lower proximal protruding tongue 274 and the lower proximal pinhole of the lower distal protruding tongue 265, respectively, with an upwardly protruding distal. And including proximal pivot pins. See FIG.

FIGS. 5-8 generate a control motion for axially moving a closing member configured to add closing and opening motion to a portion of a surgical instrument of the type described above, or a surgical end effector. It shows an embodiment of a surgical end effector 300 configured to be operably attached to an elongated shaft assembly of another surgical instrument configuration, including a closure system configured as described above. In the illustrated example, as discussed in more detail below, the surgical end effector is configured to be articulated with respect to the proximal portion of the elongated shaft assembly around the joint 339, indicated by 339 as a whole. There is. Other configurations, however, may not allow joint movement. As can be seen in FIG. 6, the joint joint 339 defines a joint movement axis BB through which the surgical end effector 300 can selectively perform joint movement. In the illustrated example, the joint motion axis BB substantially crosses the shaft axis SA-SA of the elongated shaft assembly.

The illustrated surgical end effector 300 comprises a first jaw 308 and a second jaw 309, with the second jaw 309 in an open position with respect to the first jaw 308 (FIG. 7). It can be selectively moved to and from various closed positions (FIG. 8). In the illustrated embodiment, the first jaw 308 comprises an elongated channel 302 configured to operably support the surgical staple cartridge 304 in, and the second jaw 309 includes an anvil 310. There is. However, other surgical jaw configurations can also be used without departing from the spirit and scope of the present invention. As can be seen in FIG. 5, used to provide additional support to the surgical staple cartridge 304 and by a staple driver (not shown) supported in a staple pocket 306 formed in the surgical staple cartridge 304. A support pan 305 may be attached to the surgical staple cartridge 304 to prevent it from being previously detached from the surgical staple cartridge. As can be seen in FIG. 5, the elongated channel 302 has a proximal end portion 320 that includes two upright outer walls 322. The anvil 310 includes an anvil body 312 formed on which a staple-molded lower surface 313 is formed. The proximal end 314 of the anvil body is branched by launching member slots 315 defining a pair of anvil mounting arms 316. Each anvil mounting arm 316 includes an inclined top surface 321 and also includes a laterally projecting anvil trunnion 317 and a cam slot 318 defining a cam surface or "slotted cam surface" 319. See FIG. One of the cam slots 318 may be referred to herein as a "first cam slot", the cam surface of which is referred to as a "first cam surface". Similarly, the other cam slot 318 may be referred to as a "second cam slot", the cam surface of which is referred to herein as the "second cam surface". Trunnion holes 324 for receiving the corresponding one of the anvil trunnions 317 are provided on each outer wall 322 of the elongated channel 302. Such a configuration is defined by the trunnion hole 324 and the anvil 310 can be moved to the elongated channel 302 for selective pivotable movement around the anvil axis AA across the shaft axis SA-SA. Useful for mounting on. See FIG.

In the illustrated configuration, the anvil 310 is pivotally moved to the open position by a pair of open cams 354 with respect to the elongated channel 302 and the surgical staple cartridge 304 supported therein, and the open cam 354 is anvil. It may be detachably supported in the actuator member, detachably attached to the anvil actuator member, permanently attached to the anvil actuator member, or integrally formed in the anvil actuator member. In the illustrated embodiment, the anvil actuator member comprises an end effector closing sleeve 272. See FIG. Each open cam 354 includes an outer body portion 356, the outer body portion 356 having a cam tab 358 projecting inward from it. The outer body portion 356 is configured to be snap-fitted and detachably engaged in a corresponding cam hole 355 formed within the end effector closing sleeve 272 in at least one configuration. For example, the outer body portion 356 may include a chamfer stop portion 357 configured to snap into the corresponding portion of the end effector closure sleeve wall defining the cam hole 355. Another portion of the outer body portion 356 may form a dogleg form 359 configured to be received inside the portion of the end effector closure sleeve 272 adjacent to the cam hole 355. Other snap tab configurations may also be used to detachably attach the outer body portion 356 to the end effector closure sleeve 272. In other configurations, for example, the outer body portion may not be configured to snap engage with the end effector closure sleeve 272. In such a configuration, the outer body portion can be held in place by an annular crimp ring that covers the outer body portion of the open cam and extends around the outer circumference of the end effector closure sleeve and can be crimped in place. The crimp ring acts to capture the outer body portion with respect to the outer surface of the end effector closure sleeve. The crimpling is designed to provide the end effector closure sleeve with a relatively smooth or continuous outer surface that can advantageously avoid damage to adjacent tissue and / or accumulation of tissue / fluid etc. between these components. It can actually be crimped into the annular recess formed in the end effector closure sleeve.

When the open cam 350 is introduced into the end effector closure sleeve 272, each cam tab 358 extends through the elongated slot 326 of the corresponding outer wall 322 of the elongated channel 302 and is received in the corresponding cam slot 318 of the anvil 310. To. See FIG. In such a configuration, the open cams 350 are radially opposite to each other in the end effector closure sleeve. In use, the closure tube 260 is translated distally (direction "DD") to close the anvil 310, for example, in response to the activation of the closure trigger 32. The anvil 310 is closed when the closure tube 260 is translated distally "DD" so that the distal end 275 of the end effector closure sleeve 272 comes into contact with the closure lip 311 on the anvil body 312. Specifically, the distal end 275 of the end effector closure sleeve 272 is the upper surface of the anvil mounting arm 316 as the closure tube 260 is moved distally to begin pivoting the anvil 310 to the closed position. Get on 321. For example, in one configuration, closure of the anvil 310 occurs only by contact between the end effector closure sleeve 272 and the anvil 310, not by the interaction of the open cam with the anvil. In other configurations, however, the open cam may also be configured to add a closing motion to the anvil as the closing tube 260 is moved distally. The anvil 310 is opened by translating the closing tube 260 proximally in the proximal direction "PD", which translation causes the cam tab 358 to the cam slot 318 on the cam surface 319, as shown in FIGS. 6 and 7. It is moved in the proximal direction "PD" within to pivot the anvil 310 to the open position.

Embodiment 300 of the surgical end effector uses two open cams to ensure reliable opening of the end effector jaw even under load. It is conceivable that only one open cam may be used or three or more open cams may be used without other configurations deviating from the gist and scope of the present invention. In the illustrated example, the open cam is detachably attached to an end effector closure sleeve that facilitates easy assembly or attachment of surgical end effector components to an elongated shaft assembly and their disassembly. Such configurations also allow the use of smaller or shorter articulated joint configurations that further facilitate better operation of the surgical end effector within the confined space within the patient's body. To facilitate easy removal of the open cam that snaps into place, an additional hole is provided in the end effector closure sleeve through which a ply member is inserted to close the end effector. It may be possible to remove the open cam from the sleeve. In yet other configurations, the open cam may be integrally formed within the anvil actuator member or end effector closure sleeve. For example, each open cam may have tabs, which are cut into or otherwise formed in the wall of the anvil actuator member or end effector closure sleeve and then the second jaw. It is bent, crimped, or permanently deformed inward to engage the corresponding cam surface above the portion. For example, the tab can be bent inward at a 90 degree angle to the outer wall of the end effector closure sleeve. Such a configuration avoids the need for a separate open cam component. In other variants, one or more pins may be used, but those pins are attached to the second jaw and configured to rest on the corresponding cam surface on the first jaw. Is. The pin can be pressed, knurled, and then pressed and / or welded to the first jaw, for example. The open cam configuration described above is described in the context of surgical end effectors, including anvils that are configured to support surgical staple cartridges and are configured to move relative to surgical staple cartridges. However, it will be clear to the reader that open cam configurations can also be used with other end effector configurations with jaws that are movable relative to each other.

9 and 10 show an elongated shaft assembly marked 200', incorporating many of the features of the elongated shaft assembly 200 described above. In the illustrated example, the elongated shaft assembly 200'includes a double joint link configuration marked 800 with a joint lock 810 similar to the joint lock 350 described above. The components of the joint lock 810 that are different from the components of the joint lock 350 and that may be necessary to understand the operation of the joint lock 350 will be described in more detail below. Various details regarding the joint lock 350 are incorporated herein by reference in its entirety, U.S. Patent Application No. 13 / 803,086, title of invention "ARTICULATABLE SURGICAL INSTRUMENT COMPRISING AN ARTICULATION LOCK", current. It can be found in US Patent Application Publication No. 2014/0263541. The joint lock 810 can be configured and manipulated to selectively lock the surgical end effector 300 to various joint motion positions. Such a configuration allows the surgical end effector 300 to rotate, or jointly move, with respect to the shaft closure tube 260 when the joint lock 810 is in its unlocked state.

As described above, when the proximal joint driver 230 is operatively engaged with the launch member 220 via the clutch system 400, the launch member 220 places the proximal joint driver 230 on the proximal side and / or It can be moved to the distal side. For example, by moving the launch member 220 to the proximal side, the proximal joint driver 230 can be moved to the proximal side, and similarly, by moving the launch member 220 to the distal side, the proximal joint can be moved. The driver 230 can be moved distally. The movement of the proximal joint driver 230, whether proximal or distal, allows the joint lock 810 to be unlocked, as described in more detail below. For example, as can be seen in FIG. 9, the elongated shaft assembly 200'includes a shaft frame 812 that is somewhat as wide as the first distal joint driver 820. The first distal joint driver 820 selectively moves longitudinally in the distal "DD" and proximal "PD" in response to the corresponding joint motion control motion applied thereto. Supported within the elongated shaft assembly 200'. The shaft frame 812 includes a distal end portion 814 having a downward projecting pivot pin (not shown) above it, which downward projecting pivot pin is a pivot formed in the proximal end portion 320 of the elongated channel 302. It is adapted to be received pivotally within the moving hole 328. See, for example, the same configuration shown in FIG. Such a configuration facilitates the pivotal movement of the elongated channel 302 of the surgical end effector 300 with respect to the shaft frame 812 centered on the joint motion axis BB defined by the pivot hole 328. As shown above, the joint motion axis BB crosses the shaft axis SA-SA defined by the elongated shaft assembly 200'.

Referencing FIG. 9 again, the first distal joint driver 820 includes a first or distal lock cavity 822 and a second or proximal lock cavity 824, with the first lock cavity 822. The second lock cavity 824 can be separated by an intermediate frame member 825. The joint lock 810 may further include at least one first lock element 826 disposed in at least partially in the first lock cavity 822, the first lock element 826 being the first far. The position joint driver 820 may be configured to prevent or prevent proximal movement. For example, in the embodiment shown in FIG. 9, there are three first lock elements 826 arranged in the first lock cavity 822, and all of these first lock elements 826 operate in the same parallel manner. And can act collaboratively as a single locking element. Other embodiments are also conceivable in which four or more or two or less first locking elements 826 can be utilized. Similarly, the joint lock 810 can further include at least one second lock element 828, which is at least partially located in the second lock cavity 824, the second lock element 824 being the second. The distal joint driver 820 of 1 may be configured to suppress or prevent the movement to the distal side. With respect to the particular embodiment shown in FIG. 9, there are three second locking elements 828 arranged within the second locking cavity 824, and these second locking elements 828 all operate in a similar parallel fashion. And can act collaboratively as a single locking element. Other embodiments are also conceivable in which four or more or two or less second locking elements 828 can be utilized.

In addition to the above, primarily with reference to FIG. 9, each first locking element 826 is slidably supported on the frame rail 830 and includes a locking tongue 827. Each of the first locking elements 826 has a locking aperture (not shown) therein for receiving the frame rail 830 through it. The lock tongue 827 may be disposed within the first lock cavity 822, and the lock aperture may be slidably engaged with the frame rail 830 attached to the shaft frame 812. The first locking element 826 is not oriented in a configuration perpendicular to the frame rail 830, rather the first locking element 826 is configured and configured at an angle not perpendicular to the frame rail 830. It is aligned so that the edge or side wall of the lock aperture is engaged with the frame rail 830. Further, the interaction between the side wall of the lock aperture and the frame rail 830 can generate a resistance or frictional force between them, which resistance or frictional force is the first locking element 826 and the frame rail 830. It can suppress relative movement with and, as a result, resist the proximal push force P applied to the first distal joint driver 820. In other words, the first locking element 826 can prevent, or at least suppress, the surgical end effector 300 from rotating in the direction indicated by arrow 821. When torque is applied to the end effector 300 in the direction of arrow 821, the proximal push force P will be transmitted to the distal joint driver 820. The proximal push force P will only act to enhance the lock engagement between the first locking element 826 and the frame rail 830. More specifically, the proximal push force P can be transmitted to the tongue 827 of the first locking element 826, which rotates the first locking element 826 to rotate the first locking element 826 and the frame rail. The angle defined between the 830 and the 830 can be reduced and, as a result, the bite between the side wall of the lock aperture and the frame rail 830 can be increased. Ultimately, the first locking element 826 can then lock the movement of the first distal joint driver 820 in one direction.

In order to release the first locking element 826 and rotate the surgical end effector 300 in the direction indicated by arrow 821, the proximal joint driver 230 may rotate the first locking element 826 vertically, or at least substantially substantially. It can be pulled proximally to realign to a vertical position or at least substantially realign. In such a position, the bite or resistance between the side wall of the lock aperture and the frame rail 830 can be sufficiently reduced or eliminated so that the first distal joint driver 820 can be moved proximally. To reposition the first locking element 826, the proximal joint driver 230 can be pulled proximally so that the distal arm 233 of the proximal joint driver 230 comes into contact with the first locking element 826. , The first locking element 826 is pulled to the straightening position and rotated. In various situations, the proximal joint driver 230 has a proximal arm 235 extending from it that contacts or abuts the proximal drive wall 832 of the first distal joint driver 820, bringing the distal joint driver 820 to the proximal side. It can continue to be pulled proximally until it is pulled to articulate the surgical end effector 300. In essence, proximal tensile force can be applied from the proximal joint driver 230 to the distal joint driver 820 through the interaction of the proximal arm 235 and the proximal drive wall 832, such tensile force being the first. Transmitted to the end effector 300 through the distal joint driver 820, the end effector 300 can be articulated in the direction indicated by the arrow 821, as further described below. After the surgical end effector 300 has been suitably articulated in the direction of arrow 821, the joint lock 810 can relock the first distal joint driver 820 and the surgical end effector 300 in place. One distal joint driver 820 can be released in a variety of situations.

At the same time as above, with reference to FIG. 9 again, the second locking element 828 can still remain in the oblique position while the first locking element 826 is locked and unlocked as described above. It should be understood by the reader that the second locking element 828 is aligned and aligned in an oblique position with respect to the shaft rail 830, whereas the second locking element 828 is of the first distal joint driver 820. It is not configured to interfere with, or at least substantially, interfere with motion to the proximal side. When the first distal joint driver 820 and the joint lock 810 are slid proximally as described above, the second locking element 828 changes the oblique alignment with respect to the frame rail 830 in various situations. It can be slid distally along the frame rail 830 without causing, or at least substantially changing. The second locking element 828 allows the first distal joint driver 820 and the joint lock 810 to move proximally, while the second locking element 828 is discussed in more detail below. , The first distal joint driver 820 may be configured to selectively prevent, or at least suppress, the distal movement.

Each second locking element 828 may include a locking aperture (not shown) and a locking tongue 829. The lock tongue 829 may be disposed within the second lock cavity 824, and the lock aperture may be slidably engaged with the frame rail 830 attached to the shaft frame 812. The frame rail 830 extends through the aperture of the second locking element 828. The second locking element 828 is not oriented in a configuration perpendicular to the frame rail 830, rather the second locking element 828 is configured and configured at an angle that is not perpendicular to the frame rail 830. It is aligned so that the edge or side wall of the lock aperture is engaged with the frame rail 830. Further, the interaction between the side wall of the lock aperture and the frame rail 830 can generate a resistance or frictional force between them, which resistance or frictional force is the second locking element 828 and the frame rail 830. It can suppress relative movement with and, as a result, resist the distal force D applied to the first distal joint driver 820. In other words, the second locking element 828 can prevent, or at least suppress, the surgical end effector 300 from rotating in the direction indicated by arrow 823. When torque is applied to the end effector 300 in the direction of arrow 823, the distal tensile force D will be transmitted to the first distal joint driver 820. The distal tensile force D will only act to enhance the lock engagement between the second locking element 828 and the frame rail 830. More specifically, the distal tensile force D can be transmitted to the tongue 829 of the second locking element 828, which rotates the second locking element 828 with the second locking element 828. The angle defined with the frame rail 830 can be reduced and, as a result, the bite between the side wall of the lock aperture and the frame rail 830 can be increased. Eventually, the second locking element 828 can then lock the movement of the first distal joint driver 820 in one direction.

To release the second locking element 828 and articulate the surgical end effector 300 in the direction indicated by arrow 823, the proximal joint driver 230 moves the second locking element 828 vertically, or at least substantially. It can be pushed distally to straighten to a position perpendicular to, or at least substantially straighten. In such a position, the bite or resistance between the side wall of the lock aperture and the frame rail 830 can be sufficiently reduced or eliminated so that the first distal joint driver 820 can be moved distally. To reposition the second locking element 828, the proximal joint driver 230 can be pushed distally so that the proximal arm 235 of the proximal joint driver 230 comes into contact with the second locking element 828. , The second lock element 828 is pushed into the straightening position and rotated. In various situations, the proximal joint driver 230 has a proximal arm 233 extending from it that contacts or abuts the distal drive wall 833 of the first distal joint driver 820 and distances the first distal joint driver 820. It may continue to be pushed distally until it is pushed laterally to articulate the surgical end effector 300. In essence, a distal push force can be applied from the proximal joint driver 230 to the first distal joint driver 820 through the interaction of the distal arm 233 with the distal drive wall 833, such push. Force is transmitted through the first distal joint driver 820 to allow the end effector 300 to joint in the direction indicated by arrow 823. After the surgical end effector 300 has been suitably articulated in the direction of arrow 823, the joint lock 810 can relock the first distal joint driver 820 and the surgical end effector 300 in place. One distal joint driver 820 can be released in a variety of situations.

Simultaneously with the above, the first locking element 826 can still remain in the oblique position while the second locking element 828 is locked and unlocked as described above. It should be understood by the reader that the first locking element 826 is aligned and aligned in an oblique position with respect to the shaft rail 830, whereas the first locking element 826 is of the first distal joint driver 820. It is not configured to interfere with, or at least substantially, interfere with distal motion. When the first distal joint driver 820 and joint lock 810 are slid distally as described above, the first locking element 826 changes its oblique alignment with respect to the frame rail 830 in various situations. It can be slid distally along the frame rail 830 without causing, or at least substantially changing. The first locking element 826 allows the first distal joint driver 820 and the joint lock 810 to move distally, whereas the first locking element 826 is the first, as described above. The distal joint driver 820 is configured to selectively prevent, or at least suppress, the proximal movement.

In view of the above, the joint lock 810 may be configured to resist the proximal and distal movement of the first distal joint driver 820 in the locked state. In terms of resistance, the joint lock 810 may be configured to prevent, or at least substantially prevent, the proximal and distal movement of the first distal joint driver 820. Overall, as described above, the motion towards the proximal side of the first distal joint driver 820 is resisted by the first locking element 826 when the first locking element 826 is in the locking direction, and the first The distal motion of the distal joint driver 820 of 1 is resisted by the second locking element 828 when the second locking element 828 is in the locking direction. In other words, the first locking element 826 comprises a first unidirectional locking and the second locking element 828 comprises a second unidirectional locking that locks in the opposite direction.

Although discussed in connection with the exemplary embodiments shown in FIGS. 9 and 10, due to the initial proximal movement of the proximal joint driver 230, the proximity of the first distal joint driver 820 and the joint lock 810. While the movement to the position side can be unlocked, the further movement of the proximal joint driver 230 to the proximal side drives the first distal joint driver 820 and the joint lock 810 to the proximal side. be able to. Similarly, the initial distal movement of the proximal joint driver 230 can unlock the distal movement of the first distal joint driver 820 and joint lock 810, while proximal. Further distal movement of the joint driver 230 can drive the first distal joint driver 820 and joint lock 810 to the distal side. Such an overall concept will be discussed in the context of some further exemplary embodiments disclosed below. To the extent that such arguments are the same as or largely overlap with those presented above, we will not reproduce such arguments for the sake of brevity.

Still referring to FIGS. 9 and 10, the double joint link configuration 800 is configured to establish a "push / pull" configuration when joint kinetic force is applied through the first distal joint driver 820. .. As can be seen in these figures, the first distal joint driver 820 has a first drive rack 842 formed therein. The first joint rod 844 projects distally from the first distal joint driver 820 and is attached to a first movable coupler 850 that is attached to the first distal joint driver 820 by a first ball joint 852. Has been done. The first coupler 850 is also pivotally pinned to the proximal end portion 320 of the elongated channel 302 by the first pin 854, as can be seen in FIG. The double joint link configuration 800 further comprises a second distal joint driver 860 with a second drive rack 862 formed therein. The second distal joint driver 860 is movably supported within the elongated shaft assembly 200'to move longitudinally in the distal "DD" and proximal "PD" directions. The second joint rod 864 projects distally from the second distal joint driver 860 and is attached to a second movable coupler 870 that is attached to the second distal joint driver 860 by a second ball joint 872. Has been done. The second coupler 870 is also pivotally pinned to the proximal end portion 320 of the elongated channel 302 by a second pin 874, as can be seen in FIG. As can be seen in FIG. 9, the first coupler 850 is attached to the elongated channel 302 on one outer side of the shaft axis SA and the second coupler 870 is attached to the elongated channel 302 on the opposite outer side of the shaft axis. Has been done. Therefore, by pulling one of the couplers 850 and 870 and simultaneously pushing the other coupler 850 and 870, the surgical end effector 300 joints the elongated shaft assembly 200'with respect to the joint motion axis BB. You will be exercising. In the illustrated configuration, the couplers 850, 870, and the elongated channel 302, which promote relative motion between the first distal joint driver 820 and the second distal joint driver 860, respectively, are made of relatively rigid components. However, coupler configurations with other relatively "soft" configurations may be used. For example, a cable or the like extends through one or both of the distal joint drivers 820, 860, couplers 850, 870 and ball joints 852, 872 so that they are coupled to an elongated channel to transmit joint motion motion to them. It may be promoted.

Similarly, as can be seen from FIGS. 9 and 10, the proximal pinion gear 880 and the distal pinion gear 882 are centrally located between the first drive rack 842 and the second drive rack 862 and mesh with them. It is in agreement. In an alternative embodiment, only one pinion gear or three or more pinion gears may be used. Therefore, at least one pinion gear is used. The proximal pinion gear 880 and the distal pinion gear 882 are rotatably supported within the shaft frame 812 to rotate freely with respect to them, so that the first distal joint driver 820 is placed in the distal direction "DD". When moved to, the pinion gears 870, 872 act to drive the second distal joint driver 860 in the proximal direction "PD". Similarly, when the first distal joint driver 820 is pulled in the proximal direction "PD", the pinion gears 880, 882 drive the second distal joint driver 860 in the distal direction "DD". Therefore, in order to jointly move the end effector 300 in the direction of arrow 821 about the joint movement axis BB, the joint driver 230 is operably engaged with the launching member 220 via the clutch system 400, thereby. , The launching member 220 moves or pulls the proximal joint driver 230 in the proximal direction "PD". As the proximal joint driver 230 moves in the proximal direction, the first distal joint driver 820 also moves in the proximal direction. When the first distal joint driver 820 moves in the proximal direction, the pinion gears 880, 882 act to drive the second distal joint driver 860 in the distal "DD" direction. As the first and second distal joint drivers 820, 860 move in this way, the surgical end effector 300, more specifically the elongated channel 302 of the surgical end effector 300, becomes the joint motion axis B-. It will pivot in the direction of joint movement of arrow 821 around B. Conversely, in order to joint the end effector 300 in the direction of arrow 823, the launching member 220 is actuated to push the first distal joint driver 820 in the distal "DD" direction. When the first distal joint driver 820 moves distally, the pinion gears 880, 882 act to drive the second distal joint driver 860 in the proximal direction "PD". As the first and second distal joint drivers 820, 860 move in this way, the surgical end effector 300, more specifically the elongated channel 302 of the surgical end effector 300, becomes the joint motion axis B-. It will be pivoted in the direction of joint movement of arrow 823 with B as the center.

The dual integrated link joint configuration 800 and its variants can provide a wider range of joint motion to the surgical end effector when compared to the configurations of other articulated surgical end effectors. Specifically, the monolithic link joint configurations disclosed herein can promote a range of joint motion beyond the 45-50 degree range commonly achieved by other articulated end effector configurations. Using at least one pinion gear to interface between distal joint drivers is also in use so that the end effector can be "pushed" and "pulled" in place. It can reduce the amount of "slop" or unwanted or unintended movement of the end effector. The double integrated link joint configuration disclosed herein also comprises a joint movement system with improved strength characteristics as compared to other joint movement system configurations.

As briefly described above, the intermediate launch shaft portion 222 is configured to operatively interface with a distal cut or launch beam 280. The distal emission beam 280 may have a laminated structure. With such a configuration, the distal firing beam 280 can be sufficiently flexed when the surgical end effector 300 is jointly moved about the joint movement axis BB. The distal firing beam 280 is supported for axial movement within the shaft assembly 200'and is slidably supported by two upright lateral support walls 330 formed on the proximal end of the elongated channel 302. To. Referring to FIG. 11, the distal firing beam 280 is attached to a firing member 900 that includes a vertically extending firing member body 902, the firing member body 902 having a tissue cut surface or blade 904 on it. There is. In addition, wedge threads 910 may be mounted within the surgical staple cartridge 304 for drive contact with the launching member 900. When the launching member 900 is driven distally through the cartridge body 304, the wedge surface 912 of the wedge thread 910 comes into contact with the staple driver, bringing the driver and the surgical staples supported on it into the surgical staple cartridge 304. Operate upward with.

An end effector that uses a firing beam or launching member and is capable of joint movement over a range, eg, 45 degrees, can have many challenges to overcome. To facilitate the operable joint movement of such end effectors, the launching member or firing beam must be sufficiently flexible to adapt to such range of joint movement. However, the firing beam or launching member must also avoid buckling during compressive firing loads. Various "support" or "blowing" plate configurations have been developed to provide additional support for the firing beam or launching member. Some such configurations are described in US Pat. No. 6,964,363, titles of the invention "SURGICAL STAPLING INSTRUMENT HAVING ARTICULATION JOINT SUPPORT PLATES FOR SUPPORTING A FIRING BAR" and titles 736. STAPLING INSTRUMENT INCORPORTING AN ELECTROACTIVE POLYMER ACTURATED FIRING BAR TRACK THROUGH AN ARTICULATION JOINT, the entire disclosure of which is incorporated herein by reference. Blow-out plates that provide substantial buckling resistance are also generally difficult to bend, which adds the force that the articulated joint system must handle. Other firing beam support configurations are incorporated herein by reference in their entirety, U.S. Patent Application No. 14 / 575,117, title of the invention "SURGICAL INSTRUMENTS WITH ARTICULATABLE END EFFECTORS AND MOVABLE FIRING BEAMSULP. Is disclosed in.

Referring to FIGS. 11-15, the elongated shaft assembly 200'is a plurality for laterally supporting the distal firing beam 280 when the surgical end effector 300 is articulated about the joint motion axis BB. The support link assembly 920 is further provided. As can be seen in FIG. 11, the plurality of support link assemblies 920 include a surgical end effector 300 and a central support member 922 that is movably coupled to the elongated shaft assembly 200'. For example, the central support member 922 is pivotally pinned to the proximal end 320 of the elongated channel 302 so that it is pivotable with respect to the proximal end 320 about the pivot axis PA. .. As can be seen in FIG. 11, the central support member 922 includes a distal overhang tab 923, for which the distal overhang tab 923 receives an upright support pin 332 formed on the proximal end portion 320 of the elongated channel 302. Has a distal pivotal hole 924. As can be further seen from FIG. 11, the central support member 922 further includes a proximal overhang tab 926, which proximal overhang tab 926 has an elongated proximal slot 928. The proximal slot 928 is configured to slidably receive a central support pin 816 formed on the frame portion 812. With such a configuration, the central support member 922 can, for example, pivot and move axially with respect to the elongated shaft assembly 200'. As can be seen in FIGS. 11-13, the central support member 922 further includes a centrally disposed slot 930 through which the distal firing beam 280 is movably received.

Still referring to FIGS. 11-15, the plurality of support link assemblies 920 further include a proximal support link 940 and a distal support link 950. Proximal support link 940 includes an elongated proximal body 942 with a round proximal nose portion 943 and a round distal nose portion 944. Proximal support links 940 further include a pair of downward projecting opposed proximal support walls 945, 946, defining a proximal slot 947 between them. Similarly, the distal support link 950 includes an elongated distal body 952 with a round proximal nose portion 953 and a round distal nose portion 954. The distal support link 950 further includes a pair of downward projecting opposed distal support walls 955, 956, defining a distal slot 957 between them. As can be seen in FIG. 14, the soft distal firing beam 280 extends between the proximal support walls 945, 946 of the proximal support link 940 and the distal support walls 955, 956 of the distal support link 950. It is configured. The proximal support wall 945 includes an inwardly oriented proximal arched surface 948, and the proximal support wall 946 includes an inwardly directed proximal arched surface 949 facing the inwardly oriented proximal arched surface 948. The proximal arched support surfaces 948, 949 are the lateral portion of the proximal portion of the soft distal launch beam 280 as the soft distal launch beam 280 flexes during end effector joint movement and traverses the joint. Works to support laterally. The rounded surface may adapt to the outer diameter of the distal firing beam 280 depending on the direction of joint movement. Similarly, the distal support wall 955 includes an inwardly directed distal arched surface 958, and the distal support wall 956 includes an inwardly directed distal arched surface 959 that faces the distal arched surface 958. The distal arched support surfaces 958, 959 laterally traverse the outer portion of the distal portion of the distal launch beam 280 as the distal launch beam 280 bends during joint movement of the end effector 300 and traverses the joint. Work to support. The distal arched surfaces 958, 959 may adapt to the outer diameter of the distal firing beam 280 depending on the direction of joint movement. As can be seen in FIGS. 12 and 13, the distal end 217 of the shaft spine 210 includes a distal bow-shaped spine pocket 218 with a round proximal nose portion 943 of the proximal support link 940 extending inward. The round distal nose portion 944 of the proximal support link 940 is pivotally received within the arched proximal pocket 932 of the central support member 922. In addition, the round proximal nose portion 953 of the distal support link is received within the arcuate distal support member pocket 934 at the distal end of the central support member 922. The round distal nose portion 954 of the distal support link 950 moves into a V-shaped channel cavity 334 formed within an upright lateral support wall 330 formed on the proximal end 320 of the elongated channel 302. Acceptable as possible.

Multiple support linkage assemblies can provide a high degree of lateral support due to the flexible firing beam laminate as the beam bends over a higher degree of joint motion angle. Such a configuration will also prevent the firing beam from buckling over relatively high joint motion angles under high firing loads. The elongated support link, along with the central support member, serves to provide improved lateral support to the launch beam throughout the articular motion zone as compared to many conventional support configurations. In an alternative configuration, the support links may be configured to actually interlock with the central support member at various joint motion angles. The U-shaped support link facilitates easy introduction and supports the soft support beam not only at each lateral part of the beam but also at the top, and warps upward while the firing beam is articulated during firing. To prevent that.

In embodiments where the launching member comprises a tissue cut surface, a method that prevents the launching member from accidentally advancing if the unused staple cartridge is not properly supported within the elongated channel 302 of the surgical end effector 300. It may be desirable to construct an elongated shaft assembly. For example, if there are no staple cartridges and the launching member is advanced distally through the end effector, the tissue is cut but not stapled. Similarly, if a used staple cartridge (ie, a staple cartridge in which at least some of the staples have already been fired) is present in the end effector and the firing member is advanced, the tissue will be cut. , Staples, if any, may not be complete. It will become clear that the occurrence of such a phenomenon can lead to undesired catastrophic consequences during surgical procedures. US Pat. No. 6,988,649, title of invention "SURGICAL STAPLING INSTRUMENT HAVING A SPENT CARTRIDGE LOCKOUT", No. 7,044,352, title of invention "SURGICAL STAPLING INSTRUMENT HALVING INFRING A , And No. 7,380,695, the title of the invention "SURGICAL STAPLING INSTRUMENT HAVING A SINGLE LOCKOUT MECHANISM FOR PREVENTION OF FIRING", respectively, discloses various launch member lockout configurations. Each of these US patents is incorporated herein by reference in its entirety.

Such a lockout configuration can be effectively used with various surgical staple fasteners. Such configurations, however, may not be particularly suitable for use in connection with the various surgical staple fastening instruments disclosed herein, using relatively small and short articulated joint configurations. For example, FIGS. 15-19 show a surgical end effector 300 operably attached to an elongated shaft assembly 200'by a joint 270'. The elongated shaft assembly 200'defines the shaft axis SA-SA, and the joint joint 270' is a surgical end effector for the elongated shaft assembly 200' centered on the articular motion axis BB that traverses the shaft axis SA-SA. Promotes 300 selective joint movements. In the illustrated embodiment, the dual integral link joint configuration 800 (as described above) can be used to selectively add joint motion motion to the surgical end effector 300. The elongated shaft assembly 200' includes a distal firing beam 280 of the type described above, which, when a firing motion is applied to it, is a surgical end effector from start to end. Within 300, it can be selectively moved in the axial direction. The distal firing beam 280 extends through the joint 270'and flexes around the joint motion axis BB to adapt to the joint motion of the surgical end effector 300 in the various schemes described herein. It is configured to do. In the illustrated embodiment, the joint 270'includes a central support member 922 movably attached to the distal end 814 of the shaft frame 812 and the proximal end 320 of the elongated channel 302. As described above, the central support member 922 has a distal projecting tab 923, which receives the upright support pin 332 formed on the proximal end portion 320 of the elongated channel 302. Has a distal pivot hole 924 for. The central support member 922 further includes a proximal overhang tab 926, which proximal overhang tab 926 has an elongated proximal slot 928. The proximal slot 928 is configured to slidably receive a central support pin 816 formed on the frame portion 812. The central support 922 further includes a centrally disposed slot 930 through which the distal firing beam 280 is axially received. The central support member 922 facilitates the axial passage of the distal launch beam 280 during launch, while the distal launch beam during joint motion of the surgical end effector 300 centered on the joint motion axis BB. Supports the 280 laterally.

In the illustrated embodiment, the distal firing beam 280 is erroneously advanced from the start position to the end position unless the unlaunched surgical staple cartridge 304 is operably seated within the cartridge support member or the elongated channel 302. A firing beam lock assembly 980 is used to prevent this. As can be seen in FIGS. 15-19, the firing beam lock assembly 980 in one embodiment includes a lock cam or detent 281 formed on the distal firing beam 280 so as to project upward from the top surface of the distal firing beam 280. .. The urging member 984 is supported on the central support member 922 and is attached to the central support member 922. As can be seen in FIG. 16, for example, the urging member 984 is substantially planar and includes a window 985 configured to accommodate the lock cam 281 during the joint movement of the surgical end effector 300. There is. Therefore, when the surgical end effector 300 is articulated about the articulation axis BB, the urging member 984 does not apply any urging force or load to the distal firing beam 280. This feature can avoid an increase in the magnitude of the joint kinetic force that must be generated to joint the surgical end effector 300 around the joint kinematic axis BB. The urging member 984 may be tack welded to the central support member 922, or may be attached to the central support member 922 by other fastening methods such as screws, pins, or adhesives. The window 985 may also define a lock band or portion 986 that acts to contact the lock cam 281 when the distal firing beam 280 is in the starting position. The lock cam 281 is accompanied by a distally inclined surface 283 and a proximally inclined surface 285 to reduce the magnitude of the firing and retreating forces required to move the distal firing beam 280 axially. Can be formed. See FIG.

As described above, the distal firing beam 280 is operably mounted on the firing member body 902 with the firing member 900 including the tissue cutting surface 904. In an alternative configuration, the tissue cut surface may be attached to a portion of the distal firing beam 280, or may be formed separately on or directly supported by that portion. .. In the illustrated configuration, a laterally extending foot 905 is formed at the bottom of the launching member body 902. The launching member body 902 further comprises a wedge thread engaging member 906, which wedge thread engaging member 906 is configured to engage the wedge thread in the surgical staple cartridge 304, as discussed in more detail below. Has been done.

FIG. 18 shows an "unused" or "unfired" surgical staple cartridge 304 properly introduced into the elongated channel 302. As can be seen in this figure, the wedge thread 910 is located in the "unfired" (recent position) position within the surgical staple cartridge 304. The wedge thread 910 is configured to engage the wedge thread engaging member 906 on the launching member 900, thereby urging the launching member 900 in the upward direction represented by arrow 988. The surface 914 is included, so that the bottom surface portion of the launching member 900 and the foot 905 are free to pass through the lock wall 307 formed by the lock opening 303 at the bottom of the elongated channel 302. When in that position, the distal firing beam 280 and firing member 900 are located within the elongated channel 302, or more precisely within the surgical staple cartridge 304 mounted therein, from the starting position shown in FIG. All of the surgical staples operably supported within the surgical staple cartridge 304 can be advanced distally to the end position within the surgical staple cartridge 304 where the wedge threads 910 have finished ejecting. In such a configuration, after the launch member 900 has been fully launched (ie, fully advanced from the start position to the end position within the surgical staple cartridge 304), the launch member 900 has started as shown in FIG. Retreat to position again. The wedge thread 910 is advanced distally to the end position in the staple cartridge 304 by the launch member 900, and since the launch member 900 is not attached to the wedge thread 910, the launch member 900 returns to the start position. When retracted, the wedge thread 910 is still in the end position within the surgical staple cartridge 304 and does not return the launching member 900 to the start position again. Therefore, the surgical staple cartridge 304 is said to be in a "after", "used", or "launched" state. As can be seen in FIG. 19, when the wedge thread is not in the unlaunched state, the bottom of the body portion 902 and the foot 905 of the launch member 900 are brought to the lock cam 281 on the distal launch beam 280 by the lock band 986 of the urging member 984. The urging motion applied extends into the lock opening 303 at the bottom of the elongated channel 302. When in that position, if the clinician deliberately attempts to refire the used surgical staple cartridge, the body portion 902 and / or the foot 905 will come into contact with the wall 307 of the elongated channel 302 and also initiate. It will be prevented from moving from the position to the end position. Thus, the firing beam lock assembly 980 is a distal firing beam 280 as well as a firing member if an unlaunched or unused surgical staple cartridge is not properly / operably introduced into the elongated channel of the surgical end effector. Prevents the 900 from advancing from the start position to the end position. It will also be apparent that the firing beam lock assembly 980 prevents the distal firing beam 280 from advancing when no staple cartridge has been introduced into the elongated channel 302. Centered on the joint motion axis BB, without the additional load applied to the distal firing beam, which may result in increased joint motion force for joint motion of the surgical end effector. In addition to adapting to the joint movement of the surgical end effector 300, the launch beam lock assembly 980 is distal across the lockout wall, regardless of whether the end effector jaw is open or closed. When advanced, no additional load is applied to the launch member and / or the distal launch beam.

FIG. 20A shows another embodiment 300'of a joint motion surgical end effector using a firing beam lock assembly 980'with an urging member 984' mounted within an end effector closure sleeve 272. As can be seen in this figure, for example, the urging member 984'applies an urging force to the tilted or tapered portion 283' of the distal firing beam 280'. The firing beam lock assembly 980'otherwise operates in the same manner as described above for the firing beam lock assembly 980'. More specifically, the urging member 984'applies an urging force to the distal firing beam 280' that pushes the distal firing beam 280'and the firing member attached to it downward within the elongated channel. An unused surgical staple cartridge, with the wedge thread or other staple ejector member in the unlaunched position, to move the launch member / launch beam out of engagement with the lock wall. If not properly introduced into the staple channel or cartridge support member to operably engage with, the launch member / launch beam is prevented from being axially advanced from the start position to the end position. Will be.

21-25 show a portion of another elongated shaft assembly 1200 similar to the elongated shaft assembly 200 described above, except for various differences described in more detail below. The components of the elongated shaft assembly 1200 described in detail above are referred to by similar element codes for brevity, eg, when used with each part of the surgical instrument 10 described above, the shaft. We will not go into further detail beyond what may be necessary to understand the behavior of the assembly 1200. As can be seen in FIG. 21, the elongated shaft assembly 1200 includes a joint lock 1810, which is substantially equivalent to the joint lock 810 and operates in essentially the same manner. As can be seen in FIG. 22, the elongated shaft assembly 1200 includes a shaft frame 1812, which is configured to movably support the proximal portion 1821 of the first distal joint driver 1820. It has a proximal cavity 1815. The first distal joint driver 1820 has an elongated shaft that selectively moves longitudinally in the distal "DD" and proximal "PD" in response to joint motion control motion applied thereto. It is movably supported within the assembly 1200. The shaft frame 1812 further includes a distal end portion 1814 formed on which a pivot pin 1818 is formed. The pivot pin 1818 is adapted to be pivotally received within the pivot hole (not shown) of the proximal end portion 1320 of the elongated channel 1302 of the surgical end effector 1300. Such a configuration facilitates the pivotal movement (ie, joint movement) of the elongated channel 1302 with respect to the shaft frame 1812 about the joint movement axis BB defined by the pivot hole and pin 1818. The shaft frame 1812 further includes a centrally disposed cavity 1817 and a distal notch 1819, the distal notch 1819 being disposed between the distal end 1814 and the centrally disposed cavity 1817.

The shaft assembly 1200 further includes a second distal joint driver 1860, which includes an endless member 1862 rotatably pivoted on the proximal pulley 1840 and the distal pulley 1340. Be prepared. Still referring to FIG. 22, the proximal pulley 1840 is rotatably pivotally supported on the pulley spindle 1842, and the pulley spindle 1842 is mounted in the centrally arranged cavity 1817 in the shaft frame 1812. The distal pulley 1340 is non-rotatably supported or formed on the proximal end 1320 of the elongated channel 1302 of the surgical end effector 1300. In one form, the endless member 1862 comprises a cable made of, for example, stainless steel, tungsten, aluminum, titanium and the like. The cable may have a braided or multi-stranded structure with varying numbers of strands to obtain the desired level of tensile strength and flexibility. In various configurations, for example, the cable 2382 ranges from 0.08 cm to 0.20 cm (0.03 inch to 0.08 inch), more preferably 0.13 cm to 0.20 cm. It can have a diameter in the range (0.05 inches to 0.08 inches). Preferred cables can be made from, for example, semi-rigid to fully rigid 300 ferritic steels. In various configurations, the cable may also be coated with, for example, Teflon®, copper, etc. to improve lubricity and / or reduce elongation. For example, by crimping, a first lug 1863 is attached to one end of the cable and a second lug 1864 is attached to the other end of the cable. The cable is stretched under tension while the ends and / or lugs 1863, 1864 are welded, glued and mechanically fastened to each other to form the endless member 1862. Spindle 1842 may include a cam mount that engages the pulley 1840 so as to move the proximal pulley 1840 to the proximal side. Other forms of tension adjusting configurations, such as belt tensioners, turnbuckle configurations, may also be used to tension the endless member 1862.

Still referring to FIG. 22, the endless member 1862 is coupled to the distal end 1821 of the first distal joint driver 1820 by a coupler assembly 1830. The coupler assembly 1830 comprises an upper coupler portion 1832 formed on the distal end 1822 of the first distal joint driver 1820 and a lower coupler portion 1834. The lower coupler portion 1834 is formed with two cradle 1835 configured to receive lugs 1862, 1864 inside. A pair of mounting pins 1836 are configured to be pressed into holes 1837 of the upper coupler portion 1832 to secure the two coupler portions 1832 and 1834 to each other. Other fastening configurations, screws, rivets, adhesives and the like may be used. When the endless member 1862 is pivotally supported on the pulleys 1840 and 1340, the coupler assembly 1830 responds to the axial movement of the first distal joint driver 1820 and shafts within the distal notch 1819 of the shaft frame 1812. Move freely in any direction. The joint motion motion generated by the axial movement of the first distal joint driver 1820 is transmitted to the second distal joint driver 1860 or the endless member 1862. A mounting ball or lug 1866 is mounted on the endless member 1862 and is received in a groove or pocket 1342 formed in the distal pulley 1340. Therefore, the movement of the endless member 1862 is transmitted to the surgical end effector 1300, more specifically to the elongated channel 1302 of the surgical end effector 1300, and causes the end effector to jointly move around the joint movement axis BB. Thus, when the first distal joint driver 1820 is moved in the distal "DD" direction, the endless member 1862 will have a surgical end centered on the joint motion axis BB in the joint motion direction represented by arrow 823. The effector 1300 is jointly moved. See FIG. 21. Similarly, when the first distal joint driver 1820 is moved in the proximal direction "PD", the endless member 1862 is surgically centered on the joint movement axis BB in the joint movement direction represented by arrow 821. The end effector 1300 is jointly moved. See FIGS. 21 and 25. As shown in FIG. 21, the joint movement direction 823 is opposite to the joint movement direction 821.

26-31 show a portion of another elongated shaft assembly 2200 similar to the elongated shaft assembly 200 described above, except for various differences described in more detail below. The components of the elongated shaft assembly 2200 described in detail above are referred to by similar element codes for brevity, eg, when used with each part of the surgical instrument 10 described above. We will not go into further detail beyond what may be necessary to understand the operation of the shaft assembly 2200. As can be seen in FIG. 26, the elongated shaft assembly 2200 includes a proximal housing or nozzle 201 consisting of nozzle portions 202 and 203. The elongated shaft assembly 2200 further includes an anvil actuator member in the form of a closure tube 2260 that can be used to close and / or open the anvil 2310 of the surgical end effector 2300 that is operably attached. As can be seen in FIG. 26, the elongated shaft assembly 2200 includes a proximal spine 2210 configured to operably interface with the joint lock 2350. The proximal spine 2210 slidably supports the launching member 2220 therein, and the closure tube 2260 extending around the proximal spine 2210 slidably. It is composed. The proximal spine 2210 also slidably supports the proximal joint driver 2230. Proximal joint driver 2230 has a distal end 2231 configured to operably engage joint lock 2350.

In the configuration shown, the proximal spine 2210 includes a proximal end 2211 that is rotatably supported within the chassis 240. In one configuration, for example, the proximal end 2211 of the proximal spine 2210 is formed with a thread 2214 so that it can be screwed into a spine bearing configured to be supported within the chassis 240. Such a configuration facilitates the rotatable attachment of the proximal spine 2210 to the chassis 240 so that the proximal spine 2210 can be selectively rotated with respect to the chassis 240 about the shaft axis SA-SA. The proximal end of the closure tube 2260 is attached to a closure shuttle supported within the chassis, as described in detail above. When the elongated shaft assembly 2200 is operably coupled to the handle or housing of the surgical instrument 10, the closure trigger operates to advance the closure tube 2260 distally.

As also mentioned above, the elongated shaft assembly 2200 further includes a launching member 2220 that is supported to move axially within the proximal spine 2210. The launch member 2220 includes an intermediate launch shaft portion 2222 configured to be attached to a distal cut or launch beam assembly 2280. See FIG. 27. The intermediate launch shaft portion 2222 may include a longitudinal slot 2223 at its distal end, which longitudinal slot 2223 may be configured to receive tabs on the proximal end of the distal launch beam assembly 2280. .. The longitudinal slot 2223 and proximal end 2280 of the distal firing beam assembly 2280 can be sized and configured to allow relative movement between them and may also include slip joints. The slip joint moves the intermediate launch shaft portion 2222 of the launch drive 2220 to articulate the end effector 300 without moving the distal launch beam assembly 2280, or at least substantially. It can be possible. When the surgical end effector 2300 is suitably oriented, the proximal side wall of the longitudinal slot 2223 is tabbed to advance the distal firing beam assembly 2280 and launch a staple cartridge that can be supported within the end effector 300. The intermediate launch shaft portion 2222 can be advanced distally until contact. Proximal spine 2210 is also bound to distal spine 2212.

Similar to the elongated shaft assembly 200, the elongated shaft assembly 2200 shown includes a clutch assembly 2400 that may be configured to selectively and releasably couple the proximal joint driver 2230 to the launching member 2220. In one form, the clutch assembly 2400 includes a lock collar or sleeve 2402 disposed around the launch member 2220, the lock sleeve 2402 is an engaging position where the lock sleeve 2402 couples the proximal joint driver 2230 to the launch member 2220. And the proximal joint driver 2230 may be rotated between the disengaged positions that are not operably coupled to the launching member 2220. When the lock sleeve 2402 is in its engaging position, the launch member 2220 moves distally to allow the proximal joint driver 2230 to move distally, and the launch member 2220 corresponds accordingly. By moving to the proximal side, the proximal joint driver 2230 can be moved to the proximal side. When the lock sleeve 2402 is in its disengaged position, the movement of the launching member 2220 is not transmitted to the proximal joint driver 2230 and as a result the launching member 2220 moves independently of the proximal joint driver 2230. be able to. Under various circumstances, the proximal joint driver 2230 may be held in place by the joint lock 2350 when the proximal joint driver 2230 has not been moved proximally or distally by the launching member 2220.

As described above, the lock sleeve 2402 may comprise a cylindrical or at least substantially cylindrical body in which a longitudinal aperture 2403 configured to receive the launching member 2220 is defined. The lock sleeve 2402 may include an inwardly facing lock protrusion 2404 and an outwardly facing locking member 2406 facing in the radial direction. The locking member 2404 may be configured to selectively engage the launching member 2220. More specifically, when the lock sleeve 2402 is in the engaging position, the lock overhang 2404 is located within the drive notch 2224 defined in the launch member 2220 so that the distal push force and / or the proximal tension Force can be transmitted from the launching member 2220 to the lock sleeve 2402. When the lock sleeve 2402 is in its engaging position, the second locking member 2406 is received within the drive notch 2232 defined in the joint driver 2230, thereby exerting a distal push force and / or on the lock sleeve 2402. Alternatively, the proximal tensile force may be transmitted to the proximal joint driver 2230. In essence, the launch member 2220, the lock sleeve 2402, and the proximal joint driver 2230 will move with each other when the lock sleeve 2402 is in its engaging position. On the other hand, when the lock sleeve 2402 is in its disengaged position, the lock overhang 2404 cannot be located within the drive notch 2224 of the launching member 2220, resulting in a distal push and / or proximal tensile force. Cannot be transmitted from the launching member 2220 to the lock sleeve 2402. Accordingly, distal pushing and / or proximal tensile forces cannot be transmitted to the proximal joint driver 2230. Under such circumstances, the launch member 2220 may slide proximally and / or distally to the lock sleeve 2402 and the proximal joint driver 2230.

Similarly, as described above, the elongated shaft assembly 2200 further includes a switch drum 2500 that is rotatably received on the closed tube 2260. The switch drum 2500 comprises a hollow shaft segment 2502 formed with a shaft boss 2504 for receiving the outward protrusion actuating pin 2410 therein. In various situations, the actuating pin 2410 extends through the slot into the longitudinal slot provided in the lock sleeve 2402 and its axial direction when the lock sleeve 2402 is engaged with the joint driver 2230. Make exercise easier. The rotary torsion spring 2420 is configured to engage a boss 2504 on the switch drum 2500 and a portion of the nozzle housing 203 to apply urging force to the switch drum 2500. The switch drum 2500 may further include, at least partially, a circumferential opening 2506 defined therein, the opening accepting a circumferential mount extending from nozzle halves 202, 203. However, it may be configured to allow relative rotation between the switch drum 2500 and the proximal nozzle 201 but not translation. As described above, when the switch drum 2500 rotates, the actuating pin 2410 and the lock sleeve 2402 will eventually rotate between their engaging and disengaging positions. Thus, in essence, the nozzle 201 is articulated in the various schemes described above, as well as in the various schemes of US Patent Application No. 13 / 803,086 and current US Patent Application Publication No. 2014/0263541. It can be used to operably engage and disengage the system and the launch drive system.

With reference to FIG. 27, the closure tube assembly 2260 includes a double pivot closure sleeve assembly 2271. According to various forms, the double pivot closure sleeve assembly 2271 includes an end effector closure sleeve 2272 with upper and lower distal protruding tongues. The upper double drive link 2277 includes an upwardly projecting distal and proximal pivot pins, each of which is an upper proximal projecting tongue on a closing tube 2260. Engage with the upper distal pinhole in and the upper proximal pinhole in the upper distal protruding tongue. The lower double pivot link 2278 includes an upwardly projecting distal pivot pin and a proximal pivot pin, each of which is a lower distal pin of the lower proximal protruding tongue. Engage with the hole and the lower proximal pinhole of the lower distal protruding tongue.

The elongated shaft assembly 2200 also includes a surgical end effector 2300 similar to the surgical end effector 300 described above. As can be seen in FIG. 27, the surgical end effector 2300 includes an elongated channel 2302, which elongated channel 2302 is configured to operably support the surgical staple cartridge 2304 inside. The elongated channel 2302 has a proximal end portion 2320 that includes two upright outer walls 2322. The surgical end effector 2300 further includes an anvil 2310, which has an anvil body 2312 formed on which a stapled lower surface 2313 is formed. The proximal end 2314 of the anvil body 2312 is branched by a launcher slot 2315 to form two anvil mounting arms 2316. Each anvil mounting arm 2316 includes a laterally projecting anvil trunnion 2317. A trunnion slot 2324 for receiving the corresponding one of the anvil trunnions 2317 is provided on each outer wall 2322 of the elongated channel 2302. Such a configuration acts to movably anchor the anvil 2310 to the elongated channel 2302 so that it selectively pivotally moves between the open position and the closed or clamped position. The anvil 2310 is moved to the closed position by advancing the closure tube 2260, more specifically the end effector closure sleeve 2272, distally onto the tapered mounting arm 2316, thereby closing the anvil 2310. It will be moved distally while pivoting to position. A horseshoe-shaped opening 2273 configured to engage an upright tab 2318 on the anvil 2310 of the end effector 2300 is provided on the end effector closing sleeve 2272. To open the anvil 2310, the closure tube 2260, more specifically the end effector closure sleeve 2272, is moved proximally. In doing so, the central tab portion defined by the horseshoe-shaped opening 2273 works with the tab 2318 on the anvil 2310 to pivot the anvil 2310 back into the open position.

With reference to FIGS. 26, 28 and 29, as described above, the elongated shaft assembly 2200 includes a joint lock 2350 that is substantially equivalent to the joint locks 350 and 810 described above. The components of the joint lock 2350, which are different from the components of the joint lock 350 and are necessary for understanding the operation of the joint lock 350, will be described in more detail below. As described above, the joint lock 2350 may be configured and manipulated to selectively lock the end effector 2300 in place. Such a configuration allows the surgical end effector 2300 to rotate, or jointly move, with respect to the shaft closure tube 2260 when the joint lock 2350 is in the unlocked state. In addition to the above, when the proximal joint driver 2230 is operatively engaged with the launching member 2220 via the clutch system 2400, the launching member 2220 makes the proximal joint driver 2230 proximal and / or distal. Can be moved to. The movement of the proximal joint driver 2230, whether proximal or distal, allows the joint lock 2350 to be unlocked, as described above. This embodiment includes a proximal lock adapter member 2360 that is movably supported between the proximal spine 2210 and the distal spine 2212. To receive in the proximal lock adapter 2360 a first locking element 2364 and a second locking element 2366 axially supported on a frame rail 2368 extending between the proximal frame 2210 and the distal frame 2212. Includes a lock cavity 2362. The joint lock 2350 operates in the various manners described above and is not described further herein for brevity.

As can be seen in FIGS. 26, 28 and 29, a first distal joint driver 2370 is attached to the proximal lock adapter 2360. The first distal joint driver 2370 is operably attached to a second distal joint driver 2380 that operably interfaces with the elongated channel 2302 of the end effector 2300. The second distal joint driver 2380 comprises a cable 2382 rotatably pivoted on the proximal pulley 2383 and the distal pulley 2392. The distal pulley 2392 is non-rotatably supported or integrally formed on the end effector mounting assembly 2390 and includes a detent or pocket 2396. In the illustrated example, the end effector mounting assembly 2390 is moved to the proximal end 2320 of the elongated channel 2302 by a spring pin 2393 extending through a hole in the end effector mounting assembly 2390 and a hole 2394 in the proximal end 2320 of the elongated channel 2302. It is installed impossible. The proximal pulley 2383 is rotatably supported on the distal spine 2212. The distal end of the distal spine 2212 has a pivot pin 2213 formed on it, and the pivot pin 2213 is rotatably received within the pivot hole 2395 formed in the end effector mounting assembly 2390. It is configured as follows. Such a configuration facilitates the pivotal movement (ie, joint movement) of the elongated channel 2302 with respect to the distal spine 2212, centered on the joint movement axis BB defined by the pivot hole 2395 and pin 2213.

In one form, the cable 2382 can be made of, for example, stainless steel, tungsten, aluminum, titanium and the like. The cable may have a braided or multi-stranded structure with varying numbers of strands to obtain the desired level of tensile strength and flexibility. In various configurations, for example, the cable 2382 ranges from 0.08 cm to 0.20 cm (0.03 inch to 0.08 inch), more preferably 0.13 cm to 0.20 cm. It can have a diameter in the range (0.05 inches to 0.08 inches). Preferred cables can be made from, for example, semi-rigid to fully rigid 300 ferritic steels. In various configurations, the cable may also be coated with, for example, Teflon®, copper, etc. to improve lubricity and / or reduce elongation. In the illustrated example, the cable 2382 has a lug 2384 attached to one end thereof, for example by a crimp, and a lug 2385 attached to the other end. The first distal joint driver 2370 includes a pair of separated cleats 2372, 2374, the cleats 2372, 2374 being sufficiently separated from each other to accommodate lugs 2384, 2385 between them. For example, the proximal cleat 2372 includes a proximal slot 2373 for receiving a portion of the cable 2382 adjacent to the lug 2384, and the distal cleat 2374 is adjacent to the lug 2385 of the cable 2382. Includes a distal slot 2375 for receiving the corresponding portion. Slots 2373 and 2375 are dimensioned relative to lugs 2384, 2385, respectively, to prevent lugs 2384, 2385 from passing through them, respectively. The proximal slot 2375 is oriented at an angle relative to the distal slot 2375 so that it firmly grips the corresponding portion of the cable 2382 therein. See FIG. A mounting ball or lug 2398 is mounted on the endless member 2382 and is received in a detent or pocket 2396 formed in the distal pulley 2392. See FIG. 31. Thus, when the first distal joint driver 2370 is axially retracted in the proximal direction "PD" in the manner described above, the endless member 2382 is oriented in the direction represented by arrow 2376 in FIG. The end effector 2300 will be jointly moved. Conversely, when the first distal joint driver 2370 is axially retracted in the distal "DD" direction, the surgical end effector 2300 is articulated in the direction indicated by arrow 2399 in FIG. .. In addition, the proximal and distal cleats 2372, 2374 are sufficiently spaced between them to accommodate the lugs 2384, 2385. To apply sufficient tension to the cable 2382, a tension adjusting wedge 2378 is used as shown in FIGS. 29-32 so that when the cable is activated, a joint motion motion is applied to the end effector 2300. .. In the alternative configuration shown in FIG. 35, the proximal cleat 2374'is initially not attached to the first joint driver 2370. Proximal cleats 2374'are placed on the first distal joint driver 2370 so as to capture the lugs 2384 and 2385 between the distal cleats 2372 and the proximal cleats 2374'. Proximal cleats 2374'are moved towards distal cleats 2372 until sufficient tension is applied to cable 2382, then proximal cleats 2374' are first distal joint driver 2370. Attached to. For example, the proximal cleat 2374'can be attached to the first distal joint driver 2370 by laser welding or other suitable form of attachment or fastener configuration.

With reference to FIGS. 36-39, the surgical instrument comprises, for example, a centrally launched beam support member 2286, which extends throughout the joint to support the flexible firing beam assembly 2280. It is configured in. In one form, the centrally-launched beam support member 2286 comprises a flexible plate member or band with a downwardly projecting distal mounting tab 2287 that is attached to a surgical end effector and an upwardly extending proximal end that is attached to an elongated shaft assembly. Includes portion 2288 and. In at least one configuration, the distal mounting tab 2287 is attached to the end effector mounting assembly 2390 by a spring pin 2393 and the proximal end portion 2288 is pinned to the distal spine 2212 by a pin (not shown). The central launch beam support member 2286 is located along the centerline or shaft axis of the device and acts to support the launch beam during joint movement. It is located on the outer side of the firing beam, thereby deviating from the shaft axis and increasing the tension and compressive forces received during joint movement, a "blow-out" plate or lateral support plate. It is different from the configuration using. In the illustrated example, the longitudinally movable flexible firing beam assembly 2280 comprises a stacked beam structure comprising at least two beam layers, the at least one beam layer having one adjacent outer side of the central firing beam support member. It is configured to pass, and at least one other beam member is configured to pass through another adjacent outer portion of the centrally emitted beam support member. In the illustrated example, the two laminates 2282 and 2284 are configured to pass near each side of the flexible tension transfer member. See, for example, FIGS. 35 and 36. In various embodiments, the laminates 2282 and 2284 may comprise, for example, stainless steel bands that are interconnected by welding or pinning to each other at their proximal ends, but their corresponding distal ends. The portions are not connected to each other so that the laminates or bands separate from each other when the end effectors are articulated. Each pair of laminates or bands 2282, 2284 is represented as the side firing band assembly 2285 of the firing beam assembly 2280. Thus, as shown in FIG. 36, one lateral launch band assembly 2285 is axially moved relative to the central joint bar 2286 by a series of lateral load bearing members 2290 so that each outer side of the central joint bar 2286. Supported by the department. Each lateral load bearing member 2290 is made of, for example, stainless steel, aluminum, titanium, liquid crystal polymer material, plastic material, nylon, acrylonitrile butadiene styrene (ABS), polyethylene, etc., and is formed with arched ends 2292 on both sides. Can be done. Each lateral load bearing member 2290 also has an axial passage 2294 extending through it to receive the assembly of the lateral launch band assembly 2285 and the central joint bar 2286. As most notably seen in FIG. 38, each axial passage is defined by two opposing bow-shaped surfaces 2295 that facilitate the movement of the lateral load bearing member 290 over the longitudinally movable flexible launch beam assembly 2280. ing. The lateral load bearing members 2290 are continuously arranged on the lateral launch band assembly 2285 and the central joint bar 2286, so that the opposing arched ends 2292 correspond to the adjacent lateral load bearing members 2290. It is designed to come into contact with the bow-shaped end 2292. See, for example, FIGS. 36 and 37.

Referencing FIG. 37 again, it can be seen that the proximal end portion 2288 of the central joint bar 2286 extends downward for attachment to the distal spine 2212. The distal end 2287 of the firing beam assembly 2280 is attached, for example, to the firing member 2900 of the type and structure described above. As can be seen in this figure, the launch member 2900 includes a vertically extending launch member body 2902, the launch member body 902 having a tissue cut surface or blade 2904 on it. In addition, wedge threads 2910 may be mounted within the surgical staple cartridge 2304 for drive contact with the launching member 2900. When the launching member 2900 is driven distally through the cartridge body 2304, the wedge surface 2912 of the wedge thread 2910 contacts the staple driver, pointing the driver and the surgical staples supported on it upward within the cartridge 2304. To operate. The firing beam assembly 2280 is operated in the various manners described above. When the firing beam assembly 2280 is advanced distally around the articulation joint, the lateral load bearing member 2290 can help resist the buckling load on the firing beam assembly 2280. The lateral load support member 2290 can also reduce the amount of force required to joint the end effector and can adapt to larger joint movement angles compared to other joint joint configurations. The fixed central firing beam support member 2286 serves to support the tensile load generated during joint movement and firing.

As described above, the firing beam assembly comprises a stacked beam structure that includes at least two beam layers. When the firing beam assembly is advanced distally (during firing), the firing beam assembly is essentially branched by a central firing beam support member, so that each part of the firing beam assembly (ie, stacking) is centrally fired. It will pass on both sides of the beam support member.

40-43 show the portion of another firing beam assembly 2280'attached to the firing member 2900. As can be seen in this figure, the launch beam assembly 2280 has two outer beams or layers 228', each having a thickness indicated by "a", and four centers, each having a thickness indicated by "b". It has a laminated structure including layer 2284'. In at least one configuration, for example, "a" is about 0.013 centimeters to 0.020 centimeters (0.005 inches to 0.008 inches), more preferably 0.020 centimeters (0.008 inches). “B” may be about 0.020 centimeters to 0.030 centimeters (0.008 inches to 0.012 inches), more preferably 0.025 centimeters (0.010 inches). Good. However, other thicknesses may be used. In the illustrated example, "a" is thinner than "b". In another example, "a" is thicker than "b". In an alternative configuration, for example, the laminate may consist of three different thicknesses "a", "b", "c", where "a" = 0.015 centimeters (0.006 inches). ), "B" = 0.020 cm (0.008 inch), "c" = 0.025 cm (0.010 inch) (the thickest laminate or band is in the center of the assembly). In various configurations, an even number of laminates or bands may be present, where "c" is the single thickest laminate in the center.

This laminate composition is appropriate due to the magnitude of the strain applied to the beam assembly based on the thickness and distance from the bending centerline. Thicker laminates or bands closer to the centerline can receive the same level of strain as thinner laminates or bands away from the centerline, but this is because the thinner laminates or bands overlap each other. This is because, in view of the fact that it has been done, it must be bent more. The radius of curvature becomes steeper inside the curve away from the centerline. Given the same radius of curvature, thicker laminates or bands tend to be subject to greater internal stresses than thinner laminates. Therefore, a thinner side laminate or band with the smallest radius of curvature may have the same plastic deformation potential as a thicker laminate or band near the centerline. In other words, when the end effector makes a joint movement in a certain direction, the laminate or band located away from the direction of the joint movement has the maximum bending radius and is the laminate closest to the direction of the joint movement. The band has the densest bend radius. However, the opposite is true when the end effector is articulated in the opposite direction. Laminates inside the stack stack undergo the same deviation, but their bend radii are always within the outer bend radii. Therefore, it may be desirable to place a thinner laminate outside the stack to maintain flexibility. However, the thicker material inside to maximize stiffness and buckling resistance adds an additional advantage. Instead, if the end effector needs to joint in only one direction, the laminate or band located away from that direction of joint will receive the maximum bend radius and in the direction of joint movement. The laminated body or band located will have the densest bend radius. However, since the end effectors do not joint in the opposite direction, the reverse is no longer true and therefore the stacking stack does not have to be symmetrical. Therefore, in such a configuration, it is desirable that the thinnest laminate or band be the one that receives the steepest bend radius (the laminate or band on the side in the direction of joint movement).

Still in other configurations, the laminate or band may be made of different metals with different strengths and moduluss. For example, the outer laminate or band can have the same thickness as the inner laminate or band, the inner laminate or band is made of 300 series stainless steel, and the outer laminate or band is titanium or nitinol. Made from.

As can be seen from FIGS. 42 and 43, the distal firing beam assembly 2280'can be effectively used with the series of lateral load bearing members 2290 described above. The distal firing beam assembly 2280 can also be used with the central joint bar 2286 in the manner described above, so that some of the layers or lateral beams (or bands or laminates) are along the sides of the central joint bar. It will be clear that it moves forward in the axial direction. In some embodiments, the advancing layers on each side of the central joint bar 2286 may have the same thickness, composition, shape and composition. In other configurations, one side of the central joint bar to achieve the desired range of movement and flexibility while maintaining the desired amount of stiffness to avoid buckling during firing. The layer traveling along is having a thickness and / or composition and / or shape different from the thickness and / or composition and / or shape of the layer traveling along the other side of the central joint bar. May be good.

Figures 44-46 show a portion of another elongated shaft assembly 3200 that includes the surgical end effector 300 of the type and structure described above. Other forms of surgical end effectors may also be used. The elongated shaft assembly 3200 also includes a longitudinally movable flexible launch beam assembly 3280 that is attached to the launch member 900. In an alternative configuration, the distal end of the firing beam assembly 3280 may be configured to perform various movements within the surgical end effector without the need for a firing member attached to it. The flexible launch beam assembly 3280 may comprise the various types of laminated beam configurations described herein. In one configuration, at least two compression bands are used to laterally support the flexible launch beam assembly 8280 as it traverses the joint. The illustrated embodiment uses a total of four compression bands to laterally support the flexible firing beam as it traverses the joint. For example, the elongated shaft assembly 3200 further comprises a spine 3210 that includes a distal end 3217, the distal end 3217 having two distal cavities or notches 3219 and two proximal cavities or notches 3219'inside. Is formed in. One distal cavity 3219 houses the first proximal end 3904 of the first compression band 3900 located on one outer portion 3281 of the flexible firing beam assembly 3280 and the other distal. The cavity 3219 accommodates a second proximal end 3905 of a second compression band 3901 located on another outer portion 3283 of the flexible firing beam assembly 3280. The first compression band 3900 includes a first distal end 3902, the first distal end 3902 corresponding formed on the proximal end 320 of the elongated channel 302 of the surgical end effector 300. It is mounted in the upright lateral support wall 330. Similarly, the second compression band 3901 includes a second distal end 3907, which second distal end 3907 is also on the proximal end 320 of the elongated channel 302 of the surgical end effector 300. It is mounted within the corresponding upright lateral support wall 330 formed.

Similar to the first and second compression bands 3900, 3901, the third and fourth compression bands 3910, 3911 may be made of spring steel. As can be seen in FIGS. 44-46, the third compression band 3910 may be arranged between the first compression band 3900 and the outer portion 3281 of the flexible firing beam assembly 3280 and the fourth compression band. The 3911 may be disposed between the second compression band 3901 of the flexible firing beam assembly 3280 and another outer portion 3283. The third proximal end 3914 of the third compression band 3910 and the fourth proximal end 3915 of the fourth compression band 3911 are each movable within the corresponding proximal cavity 3219'in the spine 3210. It may be bent in a U-shaped manner so as to form a receiving urging portion. The third distal end 3912 of the third compression band 3910 and the fourth distal end 3917 of the fourth compression band 3911 are mounted within the corresponding lateral support wall 330 of the surgical end effector 300. ing.

The elongated shaft assembly 3200 further comprises a movable support link assembly 3920 for further laterally supporting the flexible launch beam assembly 3280 as the end effector 300 is articulated about the joint motion axis. As can be seen in FIGS. 44-46, the movable support link assembly 3920 comprises a surgical end effector 300 as well as a central support member 3922 movably coupled to the elongated shaft assembly 3200. In one embodiment, the central support member 3922 is pivotally pinned to the proximal end 320 of the elongated channel 302. The central support member 3922 further includes a proximal overhang tab 3926, which proximal overhang tab 3926 has an elongated proximal slot 3928. The proximal slot 3928 is configured to slidably receive the central support pin 3211 formed on the spine 3210. Such a configuration allows the dynamic movement to maintain proper lateral support on the firing beam assembly 3280, while the central support member 3922 to adapt to a wider range of joint movements. Allows relative pivotal and axial movement between and the spine 3210 of the elongated shaft assembly 3200. As can be seen in FIGS. 44-46, the central support member 3922 further includes a centrally disposed slot 3930 through which the firing beam assembly 3280 is axially received.

Further, as can be seen in FIGS. 44-46, the movable support link assembly 3920 further comprises an elongated movable pivot link 3940. The pivot link 3940 includes an elongated proximal body 3942 having a proximal protruding proximal nose portion 3943 and a distal protruding distal nose portion 3944. The pivot link 3940 further includes a first downward projecting lateral support wall 3945 and a second downward projecting lateral support wall 3946, defining a beam slot 3497 between them. As can be seen in FIG. 46, the firing beam assembly 3280 has a first lateral support wall 3945 and a second lateral support wall 3946 during the activation of the firing beam assembly 3280 and the joint movement of the surgical end effector 300. It is configured to extend in between.

It extends between the wall 3946 and the fourth compression band 3911. The first lateral support wall 3945 includes an inward first bow-shaped surface 3948 and the second lateral support wall 3946 includes an inward second bow-shaped surface 3949. The first and second arcuate surfaces 3948, 3949 serve to provide lateral support to the launch beam assembly 3280 as the launch beam assembly 3280 flexes during joint movement of the end effector 300. These rounded surfaces may be compatible with the outer diameters of the firing beam assembly 3280 and compression bands 3900, 3901, 3910, 3911, depending on the direction and extent of joint movement. Similarly, as can be seen in FIGS. 44 and 45, the distal end 3217 of the spine 3210 includes a pair of left and right opposing shaft notches 3218, within which the surgical end effector is the joint motion axis. The round proximal protrusion proximal nose portion 3943 of the pivot link 3940 extends depending on the direction of joint movement around the center. Similarly, left and right opposed support notches 3932 are provided in the central support 3922 to accommodate the distal protruding distal nose portion 3944 of the pivot link 3940, depending on the direction in which the end effector is articulated. There is. Such a notch configuration acts to provide lateral support to the pivot link 3940 while properly aligning the pivot link 3940 in a direction suitable for adapting to the direction of joint movement.

FIGS. 47-51 show another elongated shaft assembly 4200 similar to the elongated shaft assembly 2200 described above in some embodiments, except for various differences described in more detail below.

As can be seen in FIG. 50, the first proximal gear rack segment 4371 and the second proximal gear rack segment 4381 engage with the proximal power distribution gear 4390 rotatably supported by the distal spine assembly 4212. There is a good engagement. Similarly, the first distal gear rack segment 4373 and the second distal gear rack segment 4383 are in mesh engagement with the distal power distribution gear assembly 4392. Specifically, in at least one configuration, the distal power distribution gear assembly 4392 meshes with the first distal gear rack segment 4373 and the second distal gear rack segment 4383 to form a pinion gear 4393. including. The distal power distribution gear assembly 4392 further includes a drive gear 4394 configured in mesh engagement with the idler gear 4395. The idler gear 4395 is then supported in meshing engagement with a driven gear 4306 formed on the proximal end portion 4320 of the elongated channel 4302 of the surgical end effector 4300. The surgical end effector 4300 is otherwise similar to the surgical end effector 2300 and may include anvil 4310 that can be opened and closed in the various manners described above. With reference to FIGS. 48, 49 and 51, the distal spine assembly 4212 may include an upper spine portion 4212A and a lower spine portion 4212B. The distal power distribution gear assembly 4392, idler gear 4395 and driven gear portion 4306 of the elongated channel 4302 are respectively pivotally attached to or supported on the bottom portion 4212B of the distal spine assembly 4212.

The elongated shaft assembly 4200 shown in FIG. 47 includes a firing beam assembly 3280 attached to a firing member (not shown). The firing beam assembly 3280 may comprise a laminated beam configuration of the type described herein. The operation of the launching member has been described in detail above and will not be repeated for brevity. As can be seen in FIG. 47, U.S. Pat. The disclosed type of launch beam support member 4400 is used to support the launch beam assembly 3280 during the articulation of the surgical end effector 4300. FIG. 52 shows the use of the distal firing beam assembly 2280 in the elongated shaft assembly 4200. As can be seen in this figure, a plurality of lateral load bearing members 2290 are used in the manner described above to support the distal firing beam assembly 2280 when the surgical end effector 4300 is articulated. ..

FIGS. 53-58 show another elongated shaft assembly 5200 similar to the elongated shaft assembly 2200 described above in some embodiments, except for various differences described in more detail below. For the sake of brevity, the components of the elongated shaft assembly 5200 described in detail above in connection with the elongated shaft assembly 2200 are identified by similar element codes, eg, each portion of the surgical instrument 10 described above. When used in conjunction with, no further details will be given beyond what may be necessary to understand the operation of the elongated shaft assembly 5200.

Similar to the elongated shaft assembly 2200, the elongated shaft assembly 5200 shown includes a clutch assembly 2400, the clutch assembly 2400 of which is a push-and-pull joint motion to a surgical end effector 300 operably coupled to the elongated shaft assembly 5200. It is configured to operably engage with the joint motion system 5600, which is configured to add motion. In this embodiment, the clutch assembly 2400 comprises a lock collar or lock sleeve 2402 disposed around the launch member 2220, the lock sleeve 2402 engaging the lock sleeve 2402 to engage the articulation system 5600 to the launch member 2220. It can be rotated between the position and the disengagement position where the articulation system 5600 is not operably coupled to the launching member 2220. In particular, with reference to FIGS. 54-56, in the illustrated example, the joint motion system 5600 comprises a joint disc or rotating member 5602 that is supported to rotate within the nozzle 201. The joint disc 5602 is rotatably driven by a drive coupling assembly 5610. In the illustrated example, the drive coupling assembly 5610 includes a drive pin 5621 attached to the joint disc 5602. The joint drive link 5614 is operably attached to the drive pin 5612 by a connector 5616 that facilitates movement of the joint drive link 5614 with respect to the drive pin 5612. See FIGS. 54-56. The joint drive link 5614 includes a drive coupler 5618, which is configured to drively engage the outward locking member 2406 on the lock sleeve 2402. See FIG. 53.

As described above, the lock sleeve 2402 may comprise a cylindrical or at least substantially cylindrical body in which a longitudinal aperture 2403 configured to receive the launching member 2220 is defined. See FIG. 53. The lock sleeve 2402 may include an inwardly facing lock protrusion 2404 and an outwardly facing lock member 2406 that face each other in the radial direction. The locking member 2404 may be configured to selectively engage the launching member 2220. More specifically, when the lock sleeve 2402 is in the engaging position, the lock overhang 2404 is located within the drive notch 2224 defined in the launch member 2220 so that the distal push force and / or the proximal tension Force can be transmitted from the launching member 2220 to the lock sleeve 2402. When the lock sleeve 2402 is in its engaging position, the outward locking member 2406 is received within the drive notch 5619 of the drive coupler 5618 as shown in FIG. 53, and thus the distal pushing force applied to the lock sleeve 2402 and / Or proximal tensile force may be transmitted to the joint drive link 5614. In essence, the launch member 2220, the lock sleeve 2402, and the joint drive link 5614 will move with each other when the lock sleeve 2402 is in its engaging position. On the other hand, when the lock sleeve 2402 is in its disengaged position, the lock overhang 2404 cannot be located within the drive notch 2224 of the launching member 2220, resulting in a distal push and / or proximal tensile force. Cannot be transmitted from the launching member 2220 to the lock sleeve 2402. Similarly, the driving force "DF" cannot be applied to the joint disc 5602. Under such circumstances, the launch member 2220 may slide proximally and / or distally to the lock sleeve 2402 and the proximal joint driver 2230.

Similarly, as described above, the elongated shaft assembly 5200 further includes a switch drum 2500 that is rotatably received on the closed tube 2260. See FIG. 53. The switch drum 2500 comprises a hollow shaft segment 2502 formed with a shaft boss 2504 for receiving the outward protrusion actuating pin 2410 therein. In various situations, the actuating pin 2410 extends into the longitudinal slot 2401 provided in the lock sleeve 2402 and is the axis of the lock sleeve 2402 when the lock sleeve 2402 is engaged with the joint drive link 5614. Promote directional movement. The rotary torsion spring 2420 is configured to engage a boss 2504 on the switch drum 2500 and a portion of the nozzle housing 201 to apply urging force to the switch drum 2500. Similarly, as described above, the switch drum 2500 may further include an opening defined therein that is at least partially along the circumferential direction, the opening extending from the nozzle half. It may be configured to accept a circumferential mount and allow relative rotation between the switch drum 2500 and the nozzle housing 201 but not translation. As described above, when the switch drum 2500 rotates, the actuating pin 2410 and the lock sleeve 2402 will eventually rotate between their engaging and disengaging positions. Thus, essentially, the nozzle housing 201 uses the various methods described above, as well as the various methods in US Patent Application 13 / 803,086 and current US Patent Application Publication No. 2014/0263541, for joint motion. It can be used to operably engage and disengage the system 5600 and the launch drive system.

Referring again to FIGS. 53-56, the articulated motor system 5600 of the illustrated example further comprises a "first" or right joint linkage 5620 and a "second" or left joint linkage 5640. The first joint linkage 5620 includes a first joint link 5622, and the first joint link 5622 contains a first joint pin 5624 that is movably received within the first joint slot 5604 of the joint disc 5602. .. The first joint link 5622 is movably pinned to a first joint connector 5626 configured to engage the joint lock 2350. As described above, the joint lock 2350 may be configured and manipulated to selectively lock the surgical end effector 300 in place. Such a configuration allows the surgical end effector 300 to rotate, or jointly move, with respect to the shaft closure tube 2260 when the joint lock 2350 is in its unlocked state. In addition to the above, when the joint drive link 5614 is operably engaged with the launch member 2220 via the clutch system 2400, the launch member 2220 rotates the joint disk 6502 to proximal the first joint linkage 5620. Can be moved laterally and / or distally. The movement of the first joint connector 5626 of the first joint linkage 5620, whether proximal or distal, allows the joint lock 2350 to be unlocked, as described above. The proximal lock adapter 2360 is a lock for receiving a first locking element 2364 and a second locking element 2366 axially supported on a frame rail extending between the proximal frame 2210 and the distal frame. Includes cavity 2362. The operation of the joint lock 2350 operates in the various manners described above and is not described further herein for brevity. As can be seen in FIG. 53, a first distal joint driver 5370 is attached to the proximal lock adapter 2360. The first distal joint driver 5370 is operably attached to the proximal end 320 of the elongated channel 302 of the surgical end effector 300.

Similarly, as shown above, the articulated motor system 5600 in the illustrated example further comprises a "second" or left joint linkage 5640. As can be seen in FIGS. 54-56, the second joint linkage 5640 includes a second joint link 5642, the second joint link 5642 is movably received within the second joint slot 5606 of the joint disc 5602. Includes a second joint pin 5644. The second joint link 5642 is pinned to a second joint bar 5646 attached to the proximal end 320 of the elongated channel 302 of the surgical end effector 300. Referring to FIG. 54, the joint movement system 5600 has a first joint urging member 5628 received in the first joint slot 5604 and a second joint urging member received in the second joint slot 5606. It further includes a member 5648. FIG. 54 shows a joint movement system 5600 in a neutral or non-joint movement configuration. As can be seen in this figure, the first joint pin 5624 is in contact with the first joint urging member 5628, and the second joint pin 5644 is in contact with the second joint urging member 5648. However, when in its neutral position, the first and second joint urging members 5628, 5648 do not have to be in the compressed state. FIG. 55 shows that a driving force “DF” is applied to the joint disk 5602 in the proximal direction “PD” by the joint driving link 5614 in the manner described above. Applying the driving force DF in the proximal direction "PD" results in rotating the joint disc 5602 in the direction of rotation represented by arrow 5601. When the joint disc 5602 rotates in the direction of rotation 5601, the end of the second joint slot comes into contact with the second joint pin 5644 to the second joint linkage 5640 and finally to the second joint bar 5646. Apply pushing force to. Conversely, the first joint urging member 5628 pushes the first joint pin 5624 in the direction of arrow 5601 within the first joint slot 5604 so that the tensile force is in the proximal direction "PD". Added to 1 joint linkage 5620. This proximal tensile force is transmitted to the first distal joint driver 5370 through the joint lock 2350. Such "pushing and pulling motions" applied to the surgical end effector will cause the surgical end effector 300 to jointly move around the joint movement axis in the direction represented by the arrow 5300. See FIG. 53. When the joint disc 5602 is in the position shown in FIG. 55, the second joint urging member 5648 may be in a compressed state, and the first joint urging member may not be compressed. Therefore, when the force of the driving force DF on the joint driving link 5614 is interrupted, the second joint urging member 5648 may again urge the joint disc 5602 to, for example, the neutral position shown in FIG.

Conversely, as shown in FIG. 56, when the driving force "DF" is applied to the joint drive link 5614 in the distal direction "DD", the joint disc 5602 rotates in the direction of rotation represented by arrow 5603. As the joint disc 5602 rotates in the direction of rotation 5603, the end of the first joint slot 5604 contacts the first joint pin 5624 and through the joint lock 2350 to the first joint linkage 5620 and finally to the first. A pushing force is applied to the joint driver 5370 of 1. In addition, the second joint urging member 5648 pushes the second joint pin 5644 in the second joint slot 5606 in the direction of arrow 5603, whereby the tensile force is second in the proximal direction "PD". Added to 2 joint linkages 5640. This proximal tensile force is transmitted to the second joint bar 5646. Such a "pushing and pulling motion" applied to the surgical end effector 300 will cause the surgical end effector 300 to jointly move around the joint movement axis in the direction represented by arrow 5302. See FIG. 53. When the joint disc 5602 is in the position shown in FIG. 56, the first joint urging member 5628 may be in a compressed state and the second joint urging member 5648 may not be compressed. Therefore, when the force of the driving force DF on the joint driving link 5614 is interrupted, the first joint urging member 5628 may again urge the joint disc 5602 to, for example, the neutral position shown in FIG.

FIG. 57 shows the attachment of the distal end portion 814 of the shaft frame 812 to the surgical end effector 300 operably coupled to the elongated shaft assembly 5200. As described above, the distal end portion 814 has a downward protruding pivot pin (not shown) on it, the downward protruding pivot pin forming on the proximal end portion 320 of the elongated channel 302. It is adapted to be received pivotally within the pivotal hall (not shown). With such a configuration, the pivotal movement of the elongated channel 302 with respect to the shaft frame 812 about the joint motion axis BB defined by the pivot hole is promoted. As can be seen in FIG. 57, the first distal joint driver 5370 is attached to the first coupler 850 by the first ball joint 852. The first coupler 850 is also pivotally pinned to the proximal end portion 320 of the elongated channel 302 by a first pin 854, as can be seen in FIG. Similarly, the second joint bar 5646 is attached to the second coupler 870 by a second ball joint 872. The second coupler 870 is also pivotally pinned to the proximal end portion 320 of the elongated channel 302 by a second pin 874, as can be seen in FIG.

With reference to FIGS. 53 and 58, the elongated shaft assembly 5200 may also include a launch beam assembly 2280 attached to the launch member 900 of the type described above. The launch beam assembly 2280 is attached to the launch member 2220 and can be axially advanced and retracted in the various manners described above. The elongated shaft assembly 5200 further comprises a plurality of support link assemblies 920 for laterally supporting the distal firing beam 2280 as the surgical end effector 300 is articulated about the joint motion axis BB. May be good. As can be seen in FIG. 58, the plurality of support link assemblies 920 include a central support member 922 that is pivotally pinned to the proximal end 320 of the elongated channel 302 in the manner described above. The central support member 922 further includes a centrally disposed slot 930 through which the distal firing beam 2280 is axially received. A plurality of support link assemblies 920 further include a proximal support link 940 and a distal support link 950. The proximal support link 940 has a body portion 942 with a round proximal end 943 and a round distal end 944. The proximal support link 940 further includes a pair of downward projecting lateral support walls 945, defining a proximal slot between them. Similarly, the distal support link 950 includes a body portion 952 having a round proximal end 953 and a round distal end 954. The distal support link 950 further includes a pair of downward projecting lateral support walls 955, defining a distal slot between them. As can be seen in FIG. 58, the distal firing beam 2280 is configured to extend between the lateral support wall 945 of the proximal support link 940 and the lateral support wall 955 of the distal support link 950. Each support wall 945 and 955 includes an inwardly bowed surface, as described above. These support surfaces serve to provide lateral support to the distal launch beam assembly 2280 as the distal launch beam 2280 flexes during joint movement of the end effector 300. In addition, the closure tube assembly 2260 may include a dual pivot closure sleeve assembly of the type described above, configured to operably interact with the anvil of the surgical end effector 300. The operation of the closed tube assembly 2260 results in the surgical effector anvil opening and closing in the various manners described above.

FIG. 59 shows a portion of another elongated shaft assembly 5700 that may be substantially equivalent to the elongated shaft assembly 5200, except for the differences described below. Specifically, the joint disc 5702 of the joint movement system 5701 is rotated by a worm gear motor 5710 operably supported by the nozzle housing 201. In one embodiment, for example, the driven gear 5703 is formed integrally with the joint disc 5702 or is immovably attached to the joint disc 5702, resulting in meshing engagement of the motor 5710 with the worm gear drive 5712. Eggplant. In the illustrated example, the first joint rod or member 5720 can be attached directly to a portion of the surgical end effector by any of the various methods described herein. A first joint pin 5722 is attached to a first joint rod 5720 and is received in a bow-shaped first joint slot 5704 formed in a joint disc 5702. A first joint urging member 5705 is received in the first joint slot 5704 to urge contact with the first joint pin 5722. Similarly, the second joint rod or member 5730 may be attached directly or indirectly to a portion of the surgical end effector by any of the various methods described herein. The second joint pin 5732 is attached to the second joint rod 5730 and is received in the arched second joint slot 5706 formed in the joint disc 5702. A second joint urging member 5707 is received in the second joint slot 5706 to urge contact with the second joint pin 5732.

FIG. 59 shows a joint movement system 5701 in a neutral or non-joint movement configuration. As can be seen in this figure, the first joint pin 5722 is in contact with the first joint urging member 5705, and the second joint pin 5732 is in contact with the second joint urging member 5707. However, when in its neutral position, the first and second joint urging members 5705 and 5707 do not have to be in the compressed state. By activating the motor 5710 to rotate the joint disc 5702 in the direction of rotation represented by the arrow 5601, a tensile motion is applied to the first joint rod 5720 and the first joint rod 5720 is moved in the proximal direction "PD". At the same time, a pushing motion is applied to the second joint rod 5730, and the second joint rod 5730 is moved in the distal direction "DD". Conversely, by activating the motor 5710 to rotate the joint disc 5702 in the direction of rotation represented by the arrow 5603, a pushing motion is applied to the first joint rod 5720 and the first joint rod 5720 is distal. At the same time that it is moved in the direction "DD", a tensile motion is applied to the second joint rod 5730 and the second joint rod 5730 is moved in the proximal direction "PD". Such "pushing and pulling motions" applied to the surgical end effector will cause the surgical end effector to jointly move around the joint movement axis in the various manners described above.

Figures 60-65 show another joint motion system 5800 that can be used with the various elongated shaft assemblies and effector configurations described herein. In this embodiment, however, the joint movement system 5800 comprises a double joint disc assembly 5810 with a driver joint disc 5820 and a driven joint disc 5830. Even if both joint discs 5820 and 5830 are rotatably supported, for example, in the nozzle housing of an elongated shaft assembly so that both joint disc discs 5820 and 5830 can rotate independently about a common axis. Good. In various embodiments, drive motion can be applied to the driver joint disc 5820 by the joint drive link 5614 and the launch member configuration 2220 as described above. In another embodiment, rotational drive motion may be applied to the drive joint disk 5820 by the worm gear motor 5710 in the manner described above.

FIG. 61 shows one form of the drive disk 5820. As can be seen in this figure, the drive disc 5820 includes a first pair of first bow joint slots 5822L, 5822R, each having a first bow length "FL". In addition, the driver joint disc 5820 further includes a driver slot 5824 centrally located between the first joint slots 5822, as can be seen in FIG. Depending on the method used to drive the driver joint disc 5820, the joint drive link 5614 or worm gear 5710 interfaces with the driver joint disc 5820 in various ways as described above to provide rotational motion to the driver joint disc 5820. Can be added. FIG. 62 shows one form of the driven joint disc 5830. As can be seen in this figure, the driven joint disc 5830 has a second pair of second bow joint slots 5832L, each of which has a second bow length "SL" shorter than the first bow length "FL". , 5832R is included. In addition, the driven joint disc 5830 further includes a driver post 5834 configured to be movably received within the driver slot 5824.

With reference to FIGS. 60 and 63-65, the articulation system 5800 is attached directly or jointly to a portion of the surgical end effector by any of the various methods described herein. It further comprises a first joint rod 5840 to obtain. A first joint pin 5842 is attached to a first joint rod 5720 and is received in the corresponding first and second arched joint slots 5822L, 5832L. Similarly, a second joint rod or member 5850 may be attached directly to a portion of the same surgical end effector in any of the various methods described herein. A second joint pin 5852 is attached to the second joint rod 5850 and is received in the corresponding first and second arched joint slots 5822R, 5832R. FIG. 60 shows a joint movement system 5800 in a null position where the surgical end effector can be moved freely. FIG. 63 shows the placement of the joint movement system 5800 when a rotational motion is first applied to the driver joint disc 5820 in the direction indicated by the arrow 5860. As can be seen in this figure, during the initial rotation of the driver joint disc 5820, the joint slots 5822L, 5832L are inconsistent with each other, and the joint slots 5822R, 5832R are also inconsistent with each other, but the motion is still in the joint rods 5840, 5850. Not communicated. FIG. 64 shows the placement of the joint motion system 5800 when a rotational motion is subsequently applied to the driver joint disk 5820 in the direction of arrow 5860, which rotational motion is, for example, a surgical end effector with respect to the shaft axis. It is sufficient to result in a 75 degree joint movement of. As can be seen in this figure, a pushing motion is applied to the first joint rod 5840, the first joint rod 5840 is axially moved in the distal "DD" direction, and a tensile motion is the second joint rod 5850. In addition, the second joint rod 5850 is axially moved in the proximal direction "PD". The movement of the first and second joint rods 5840, 5850 in opposite directions results in the joint movements of the surgical end effectors being operably linked to them. FIG. 65 shows the arrangement of the joint motion system 5800 when a rotational motion is applied to the drive joint disk 5820 in the opposite direction represented by the arrow 5862, which rotational motion is, for example, the opposite joint motion. It is sufficient to result in a 75 degree joint movement of the surgical end effector with respect to the shaft axis in the direction. As can be seen in this figure, a pushing motion is applied to the second joint rod 5850, the second joint rod 5850 is axially moved in the distal "DD" direction, and a tensile motion is the first joint rod 5840. In addition, the first joint rod 5840 is axially moved in the proximal direction "PD". The opposite movement of the first and second joint rods 5840, 5850 results in joint movement of the surgical end effectors operably attached to them. In one configuration, the first joint rod 5840 applies only tensile force to the surgical end effector when the joint drive disc 5820 is rotated by a sufficient distance to obtain a joint motion range of 75 degrees. May be good.

FIGS. 66-70 show a surgical end effector 6300 with first and second jaws that can move simultaneously between open and closed positions with respect to shaft axis SA-SA. The first and second jaws may comprise a variety of surgical jaw configurations without departing from the spirit and scope of the present invention. Gaining access to target tissue using the jaw of a surgical end effector can sometimes be difficult. The operability of surgical end effectors, especially surgical end effectors configured to cut and staple tissue, is the distance between the points where the jaws are supported against each other and the most recent staple position. Can be improved if minimized. For example, a surgical end effector that uses only one movable jaw (ie, one of the jaws is fixed to the shaft axis) has one movable jaw that moves relatively widely to accommodate the target tissue. It may be necessary to have a range. Such a wider range of movement can complicate the process of favorably placing target tissue using end effectors. The surgical end effector 6300 uses first and second jaws that move around a common pivot axis and with respect to each other and with respect to the shaft axis. With such a configuration, for example, the distance between the pivot axis and the most recent staple position can be reduced compared to the same distance in a particular surgical end effector that uses only one movable jaw. It will be possible.

In the illustrated example, the first jaw 6310 includes an elongated channel 6312 configured to support a surgical staple cartridge 6320 inside. As can be seen in FIG. 70, the surgical staple cartridge 6320 is configured to operably support a plurality of staple drivers 6322 therein, on which the staple driver 6322 can operate the surgical staple 6324. To support. The staple driver 6322 is movably supported in a corresponding driver slot 6321 formed within the surgical staple cartridge 6320. Staple drivers 6322 are held in their respective driver slots 6321 by cartridge pans 6330, and cartridge pans 6330 are clipped to or otherwise attached to surgical staple cartridges 6320. Staple drivers 6322 are arranged in rows on each side of the elongated slot 6326 of the surgical staple cartridge 6320 to accommodate the axial passages of the firing member 6340 through it. A wedge thread 6350 is movably supported within the surgical staple cartridge 6320 and the launching member 6340 is within the distal end of the surgical staple cartridge 6320 from a starting position adjacent to the proximal end of the surgical staple cartridge 6320. It is configured to be drivenly engaged by the launching member 6340 when driven to the end position. As described above, when the wedge threads 6350 are driven distally through the surgical staple cartridge 6320, the wedge threads 6350 drive into contact with the staple drivers 6322 and direct them towards the cartridge deck surface 6323. Drive. The firing member 6340 includes a tissue cutting surface 6346, which serves to cut the tissue clamped between the jaws when the firing member 6340 is driven distally. The various types of distal launch beams (not shown) described herein are operably attached to the launch member 6340 and the intermediate launch shaft portion 2222 or other launch system configurations. The operation of the intermediate launch shaft portion 2222 to drive and retract the distal launch beam has been described in detail above and is not repeated for brevity. Other firing beam and firing system configurations (motor driven and manually driven) may also be used to power the launching member without departing from the spirit and scope of the invention.

The illustrated surgical end effector 6300 is also configured to selectively articulate about a joint motion axis BB that substantially traverses the shaft axis SA-SA. As can be seen in FIGS. 66-70, the surgical end effector 6300 includes an end effector mounting assembly 6390 so that the end effector mounting assembly 6390 is rotatably received, for example, in the mounting hole 6392 of the end effector mounting assembly 6390. It is adapted to be pivotally mounted on a distal shaft frame (not shown) that includes a pivot pin configured in. The surgical end effector 6300 can be articulated by the type of joint lock described above and the first and second joint rod configurations. As can be seen in FIG. 70, the end effector mounting assembly 6390 further includes a pair of bilateral laterally extending trunnion pins 6394. The trunnion pin 6394 extends laterally from the outer 6391 on either side of the end effector mounting assembly 6390, which also defines a pocket area 6395 configured to receive the launch member 6340 inside. There is. The trunnion pin 6394 serves to define the pivot axis PA-PA through which the first and second jaws 6310, 6360 can pivot around it. The first jaw 6310 or the proximal end 6314 of the elongated channel 6312 is a pair of opposing U-shaped or open types adapted to receive the corresponding one of the trunnion pins 6394 inside. Includes slot 6316. Such a configuration acts to movably or pivotally support the first jaw 6310 with respect to the end effector mounting assembly 6390.

The illustrated surgical end effector 6300 further comprises a second jaw 6360 that may include anvil 6362. The illustrated anvil 6362 includes an anvil body 6364 that includes an elongated slot 6366 and two stapled surfaces 6368 formed on each side. The anvil 6362 further has a proximal end portion 6370, which is also a pair of U-shaped or adapted to receive the corresponding one of the trunnion pins 6394 inside. It has an open slot 6372. Such a configuration acts to movably or pivotally support the second jaw 6360 with respect to the end effector mounting assembly 6390 so that the first and second jaws are mutually pivoted. Not only can it move with respect to it, but it can also move with respect to the shaft axis SA-SA. The first and second jaws 6310 and 6360 may be movably actuated by the various types of closure systems described herein. For example, a first closed drive system of the type described herein may be used to operate the closed tube in the manner described herein. The closure tube can also be attached to an end effector closure sleeve 6272 that can be pivotally attached to the closure tube by a double pivot closure sleeve assembly in the manner described above. As described above, for example, the axial movement of the closing tube can be controlled through the activation of the closing trigger 32. As can be seen in FIGS. 67-69, the end effector closure sleeve 6272 extends over the end effector mounting assembly 6390 and is proximal to the proximal end 6370 of the second jaw 6360 and proximal to the first jaw 6310. It is configured to engage the end 6314. At least one cam surface 6336 may be formed on the proximal end 6314 of the first jaw 6310, whereby when the distal end 6274 of the end effector closure sleeve 6272 comes into contact with the cam surface 6336. The first jaw portion 6310 is cam-driven toward the second jaw portion and the shaft axis SA-SA. Similarly, one or more cam surfaces 6376 may be formed on the proximal end portion 6370 of the second jaw 6360, thereby contacted by the distal end 6274 of the end effector closure sleeve 6272. When so, the second jaw 6360 is moved towards the first jaw 6310 and the shaft axis SA-SA. The cam surfaces 6336, 6376 may be configured and positioned relative to each other such that the first and second jaws close relative to each other at various "closing rates" or closing times. One such configuration is shown in FIG. As can be seen in FIG. 68, points P ₁ on the first jaw 6310 and corresponding points P on the second jaw 6360 when the first and second jaws are in their respective fully open positions. _The distance along the arch path between ₂ is represented by _DT . P ₁ and point P ₂ of the first and second is said to be "compatible" with each other. For example, the first point P ₁ and the second point P ₂ may each be on a common line or axis extending between them and perpendicular to the shaft axis SA-SA. Distance along the arcuate path between the another point P _A and shaft axis SA-SA of the first jaw 6310 is represented by D _1, another corresponding point P on the second jaw _The distance along another arch path between _B and the shaft axis SA-SA is represented by D ₂ . Points P _A and the point P _B is also said to correspond to each other. For example, points P _A and P _B may be on a common line or axis extending between them and perpendicular to the shaft axis SA-SA. In the illustrated configuration, the distance D2 at which the _second jaw 6360 or anvil 6362 moves from the fully open position to the closed position where the stapled surface of the anvil 6362 is located along the shaft axis SA-SA is the second. The jaw 6310 or surgical staple cartridge 6320 of ₁ is longer than the distance D1 from which the cartridge deck surface moves from the fully open position to the closed position where the cartridge deck surface is located along the shaft axis SA-SA. For example, in at least one configuration, the second jaw or anvil opens or moves over two-thirds of the distance _DT (or another distance along another path of travel between the jaws). The first jaw or staple cartridge opens or moves over one-third of the distance _DT (or other distance along yet another path of travel between the jaws) and is therefore essentially essentially. Even if the closing motion is initially applied to both jaws at the same or equivalent time, one jaw will be faster or faster than the other jaw will acquire its fully closed position. Acquire a completely closed position. For example, cam surfaces on the first and second jaws can be arranged / configured to obtain different jaw movement ratios / speeds without departing from the gist and scope of this embodiment of the invention. .. When the end effector closing sleeve 6272 is in the starting or inactive position, the opening spring 6380 (FIG. 70) is in the first jaw to urge the first and second jaws 6310, 6360 to the open position. It may be arranged between the proximal end 6314 of the portion 6310 and the proximal end 6370 of the second jaw 6360. See FIGS. 67-69.

To move the first and second jaws 6310, 6360 to the closed position (FIG. 66), the clinician activates the closure system to activate the cam surface on the proximal end 6314 of the first jaw 6310. Simultaneously contacting the 6336 and the cam surface 6376 on the proximal end 6370 of the second jaw 6360 puts the first and second jaws 6310, 6360 into the positions shown in FIG. 66 (and shaft axis SA). The end effector closure sleeve 6272 is moved distally "DD" to urge it towards (-SA). The first and second jaws 6310 and 6360 are held in this closed position while the end effector closing sleeve 6272 is held in this position. The launch system can then be actuated to axially advance the launch member 6340 distally through the surgical end effector 6300. As can be seen in FIG. 70, the launch member 6340 is slidable within the slotted passage 6318 of the elongated channel 6312 and the foot portion 6342 configured to slidably engage the slotted passage 6374 of the anvil 6362. It may have an upper tab portion 6344 adapted to be accepted in. See FIG. 69. Thus, such launch member configurations are provided during launch of the launch member (ie, during staple launch and cutting of tissue clamped between the first jaw 6310 and the second jaw 6360). , The first and second jaws 6310, 6360 serve to reliably hold in the desired distance arrangement. The first jaw cover 6315 is provided to prevent tissue and / or body fluids from entering the first and second jaws, which may interfere with or interfere with the operation of the launching member 6340, as well as for assembly purposes. It is detachably attached to the elongated channel 6312 and the second jaw cover 6363 is detachably attached to the anvil 6362.

Other firing beam and firing system configurations (motor driven and manually driven) may also be used to power the launching member without departing from the spirit and scope of the invention.

The illustrated surgical end effector 6300'is also configured to selectively articulate around the articulation axis BB that substantially traverses the shaft axis SA-SA. The end effector 6300' includes an end effector mounting assembly 6390', and the end effector mounting assembly 6390' is configured to be rotatably received, for example, in the mounting hole 6392' of the end effector mounting assembly 6390'.

Includes or open slot 6316'. Such a configuration acts to movably or pivotally support the first jaw 6310'with respect to the end effector mounting assembly 6390'.

The illustrated surgical end effector 6300'also further comprises a second jaw 6360' which may include anvil 6362'. The illustrated anvil 6362'includes an anvil body 6364' that includes an elongated slot 6366'and two staple-molded surfaces formed on each side. The anvil 6362'has an additional proximal end portion 6370', and the proximal end portion 6370'is also adapted to accept the corresponding one of the trunnion pins 6394'into a pair of U's. It has a letter-shaped or open slot 6372'. Such a configuration acts to movably or pivotally support the second jaw portion 6360'with respect to the end effector mounting assembly 6390'. The first and second jaws 6310'and 6360' are movably actuated by the various types of closure systems described herein. For example, a first closed drive system 30 may be used to operate the closed tube 260 in the manner described herein. The closure tube 260 can also be attached to the end effector closure sleeve 6272, which can be pivotally attached to the closure tube 260 by the double pivot closure sleeve assembly 271 in the manner described above. As described above, for example, the axial movement of the closing tube 260 can be controlled through the activation of the closing trigger 32. The end effector closure sleeve 6272 extends over the end effector mounting assembly 6390', with the proximal end 6370' of the second jaw 6360' and the proximal end 6314' of the first jaw 6310'. It is configured to engage. At least one cam surface 6336'may be formed on the proximal end 6314' of the first jaw 6310', whereby the distal end 6274 of the end effector closure sleeve 6272 and the cam surface 6336' Upon contact, the first jaw 6310'is cam driven towards the second jaw 6360' and the shaft axis SA-SA. Similarly, one or more cam surfaces 6376'may be formed on the proximal end portion 6370' of the second jaw 6360', thereby the distal end of the end effector closure sleeve 6272. When contacted by 6274, the second jaw 6360'is moved towards the first jaw 6310' and the shaft axis SA-SA. When the end effector closing sleeve 6272 is in the starting or inactive position, a spring (not shown) is provided to urge the first and second jaws 6310', 6360' to the open position. It may be located between the proximal end 6314'of the jaw 6310'and the proximal end 6370' of the second jaw 6360'.

To move the first and second jaws 6310', 6360' to the closed position, the clinician activates the closure system to activate the cam surface on the proximal end 6314' of the first jaw 6310'.

'Is detachably attached to the elongated channel 6312' and the second jaw cover 6363' is detachably attached to the anvil 6362'.

In the surgical end effector embodiments described herein, where both use jaws that move relative to each other and with respect to the shaft axis, one of the jaws is fixed, eg, with respect to the shaft axis, and does not move. It may offer various advantages over other surgical end effector configurations. In such a configuration, one movable jaw has a relatively wide range of movement relative to the fixed jaw so that the target tissue can be manipulated, placed and then clamped in between. Is often desirable. In embodiments where both jaws are mobile, each jaw does not require extensive motion to adapt to the manipulation, placement and clamping of the target tissue between them. For example, such reduction of anvil movement can result in improved organizational placement. Such a configuration may also make it possible to minimize the distance between the pivot axis and the first staple position. In addition, the launching member may always remain engaged with the movable jaw (anvil and elongated channels) during the opening and closing movements.

FIGS. 72-79 show another surgical end effector 6400 configured to be operably attached to an elongated shaft assembly of the type described herein that defines the shaft axis SA-SA.

As can be seen in FIG. 74, a pair of cam plates 6500 are immovably attached to, for example, the end effector mounting assembly 6490 by spring pins 6502. As further seen in FIG. 74, each cam plate 6500 has a cam slot 6504 with a closed wedge portion 6505 and an open wedge portion 6507. The closed wedge portion 6505 is formed from two opposing closed cam surfaces 6506, and the open wedge portion 6507 is formed from two opposing open cam surfaces 6508. The elongated channel 6412 includes two proximal extension actuator arms 6416, each of which has an open trunnion pinion 6418 and a closed trunnion pin 6419 projecting laterally from them. .. Open and closed trunnion pins 6418 and 6419 are accepted using the cam slot 6504 of the corresponding cam plate 6500. Such a configuration acts to movably or pivotally support the first jaw 6410 with respect to the end effector mounting assembly 6490.

Such a configuration acts to movably or pivotally support the second jaw 6460 with respect to the end effector mounting assembly 6490.

The first and second jaws 6410 and 6460 are movably actuated by the various types of closure systems described herein. For example, a first closed drive system 30 may be used to operate the closed tube in the manner described above. The closure tube 260 can also be attached to the end effector closure sleeve 657, which can be pivotally attached to the closure tube by a double pivot closure sleeve assembly in the manner described above.
