The term "proximal" refers to the portion closest to the doctor, and the term "distal" refers to the portion located opposite the doctor. It will also be understood that, for the sake of convenience and clarity, spatial terms such as "vertical", "horizontal", "up" and "down" can be used in the present invention with respect to the drawings. However, surgical instruments can be used in many orientations and positions, and these terms are not intended to be limiting and / or absolute.

[0151] Various devices and exemplary methods are provided for performing laparoscopic and minimally invasive surgical procedures. However, the reader will readily understand that the various methods and devices disclosed in the present invention can be used in a number of surgical procedures and applications, including, for example, in relation to open surgical procedures. With the advancement of this Detailed Description, the reader will also understand that the various instruments disclosed here can be inserted into a body in any way, such as through a natural orifice, through an incision or perforation formed in fabric, etc. Functional portions or portions of the instrument end actuator can be inserted directly into a patient's body or can be inserted via an access device that has a working channel through which the end actuator and the elongated drive shaft surgical instrument can be advanced.

[0152] The surgical stapling system can comprise a drive shaft and an end actuator that extends from the drive shaft. The end actuator comprises a first jaw and a second jaw. The first jaw comprises a staple cartridge. The staple cartridge is insertable into, and removable from, the first jaw; however, other modalities are provided for in which a staple cartridge is not removable, or at least readily replaceable, from the first gripper. The second claw comprises an anvil configured to deform the staples ejected from the staple cartridge. The second claw is pivoting relative to the first claw around a geometric axis of the lid; However,

other modalities are foreseen in which the first claw is pivoting in relation to the second claw. The surgical stapling system additionally comprises an articulation joint configured to allow the end actuator to be rotated or articulated in relation to the drive shaft. The end actuator is rotatable about a pivot axis that extends through the pivot joint. Other modalities are foreseen that do not include an articulation joint.

[0153] The staple cartridge comprises a cartridge body. The cartridge body includes a proximal end, a distal end, and a platform that extends between the proximal end and the distal end. In use, the staple cartridge is positioned on the first side of the fabric to be stapled and the mustache is positioned on a second side of the fabric. The anvil is moved towards the staple cartridge to compress and secure the fabric against the platform. After that, the staples removably stored in the cartridge body can be implanted in the fabric. The cartridge body includes staple cavities defined therein, the staples being removably stored in the staple cavities. The staple cavities are arranged in six longitudinal rows. Three rows of staple cavities are positioned on a first side of a longitudinal slot and three rows of staple cavities are positioned on a second side of the longitudinal slot. Other arrangements of staple cavities and staples may be possible.

[0154] Staples are supported by staple actuators on the cartridge body. The actuators are movable between a first position, or non-triggered position, and a second position, or triggered position, to eject the clamps from the clamp cavities. The actuators are retained in the cartridge body by a retainer that extends around the bottom of the cartridge body and includes resilient members configured to secure the cartridge body and retain the retainer in the cartridge body. The actuators are mobile between their non-triggered positions and their positions triggered by a slider. The slider is movable between a proximal position adjacent to the proximal end and a distal position adjacent to the distal end. The slider comprises a plurality of inclined surfaces configured to slide under the actuators and lift the actuators, and the staples held therein, towards the anvil.

[0155] In addition to the above, the slider is moved distally by a firing member. The firing member is configured to contact the slide and push the slide towards the distal end. The longitudinal slot defined in the cartridge body is configured to receive the firing member. The anvil also includes a slot configured to receive the firing member. The firing member further comprises a first cam that engages the first claw and a second cam that engages the second claw. As the firing member is advanced distally, the first cam and the second cam can control the distance, or fabric span, between the staple cartridge platform and the anvil. The firing member also comprises a knife configured to make an incision in the tissue captured between the anvil and the staple cartridge. It is desirable that the knife is positioned at least partially proximal to the inclined surfaces, so that the clamps are ejected in front of the knife.

[0156] Figure 1 depicts a motor-driven surgical system 10 that can be used to perform a variety of different surgical procedures. As can be seen in Figure 1, an example of surgical system 10 includes four interchangeable surgical tool sets 1000, 3000, 5000 and 7000 which are adapted for interchangeable use with a 500 handle set. Each interchangeable surgical tool set 1000, 3000 , 5000 and 7000 can be designed for use in connection with the performance of one or more specific surgical procedures. In another modality of the surgical system, one or more of the interchangeable surgical tool sets 1000, 3000, 5000 and 7000 can also be effectively used with a tool drive set of a robotically controlled or automated surgical system. For example, the surgical instrument sets disclosed here can be used with various robotic systems, instruments, components and methods such as those disclosed in US Patent No. 9,072,535, but not limited to them, entitled "SURGICAL STAPLING

INSTRUMENTS WITH ROTATABLE STAPLE DEPLOYMENT ARRANGEMENTS ", which is incorporated herein by reference, in its entirety.

[0157] Figure 2 illustrates the attachment of the interchangeable surgical tool set 1000 to the handle set 500. It will be understood that any of the other interchangeable tool sets 3000, 5000 and 7000 can be coupled to the handle set 500 in a similar manner. The fixing arrangement and process shown in Figure 2 can also be used in connection with fixing any of the interchangeable surgical tool sets 1000, 3000, 5000 and 7000 to a tool drive portion or tool drive housing. of a robotic system. The cable assembly 500 may comprise a cable compartment 502 that includes a pistol grip portion 504 that can be held and handled by the physician. As will be briefly discussed below, the handle set 500 operationally supports a plurality of drive systems 510, 530, which are configured to generate and apply various control movements to the corresponding portions of the interchangeable surgical tool set 1000, 3000, 5000 and / or 7000 that is operationally attached to it.

[0158] As seen in Figure 2, the handle assembly 500 may also include a handle structure 506 that operationally supports the plurality of drive systems. For example, the 506 grip structure can operationally support a "first" drive system or closing drive system, generally referred to as 510, which can be used to apply closing and opening movements to the interchangeable surgical tool set 1000, 3000, 5000 and 7000 that is fixed or operationally attached to the handle set 500. In at least one form, the closing drive system 510 may include an actuator in the form of a closing trigger 512 , pivotally supported by the grip structure 506. This arrangement allows the closing trigger 512 to be manipulated by a physician, so that when the physician holds the pistol grip portion 504 of the grip assembly 500, the trigger of closure 512 can be easily rotated from an initial or "unacted" position to an "acted" position and, more particularly, to a fully compressed position or completely actuated. In various forms, the closing drive system 510 additionally includes a set of closing links 514, which is pivotally coupled to the closing trigger 512 or otherwise interfaces with it. As will be discussed in more detail below, in the illustrated example, the closing hinge assembly 514 includes a transverse fixing pin 516 that facilitates attachment to a corresponding drive system in the surgical tool set. In use, to actuate the closing drive system 510, the physician presses the closing trigger 512 towards the pistol grip portion 504. As described in more detail in US Patent Application Serial No. 14 / 226,142, entitled SURGICAL INSTRUMENT COMPRISING A SENSOR SYSTEM, now US Patent Application Publication No. 2015/0272575 which is hereby incorporated by reference in its entirety, the closing drive system 510 is configured to lock the closing trigger 512 in position fully pressed or fully actuated when the doctor fully presses the 512 closing trigger to obtain the complete closing stroke. When the clinician wishes to unlock the closing trigger 512 to allow the closing trigger 512 to be propelled to the unacted position, the physician activates a set of closing release button 518 that allows the closing trigger to return to its unopened position. acted upon. The lock release button set 518 can also be configured to interact with various sensors that communicate with a microprocessor 560 in the grip set 500 to track the position of the lock trigger 512. Further discussion regarding configuration and operation of the 518 lock release button assembly can be found in US Patent Application Publication No. 2015/0272575.

[0159] In at least one form, the handle assembly 500 and the handle structure 506 can operationally support another drive system called in the present invention a trigger drive system 530, which is configured to apply trigger movements to the portions corresponding to the interchangeable surgical tool set that is attached to it. As described in detail in US Patent Application Publication No. 0272575, the firing drive system 530 may employ an electric motor 505 which is located in the pistol grip portion 504 of the handle assembly 500. In various forms, the motor 505 can be a brushless DC drive motor with a maximum speed of approximately

25,000 RPM, for example. In other arrangements, the 505 motor may include a brushless motor, a wireless motor, a synchronous motor, a stepper motor or any other suitable type of electric motor. The motor 505 can be powered by a power supply 522 which, in one form, can comprise a removable power source. The power source can support a plurality of lithium ion batteries ("Li ions") or other suitable ones therein. Several batteries connected in series can be used as the 522 power source for the surgical system 10. In addition, the 522 power source can be replaceable and / or rechargeable.

[0160] The 505 electric motor is configured to axially drive a longitudinally movable driving member in the distal and proximal directions depending on the polarity of the voltage applied to the motor. For example, when the motor is started in a rotating direction, the longitudinally movable drive member will be driven axially in a "DD" distal direction. When the 505 motor is driven in the opposite rotating direction, the longitudinally movable drive member will be driven axially in a proximal "PD" direction. The grip set 500 may include a switch 513 that can be configured to reverse the polarity applied to the electric motor 505 by power source 522 or otherwise control the engine 505. The grip set 500 may also include a sensor or sensors that they are configured to detect the position of the drive member and / or the direction in which the drive member is being moved. The activation of motor 505 can be controlled by a trigger trigger 532 (Figure 1) pivotally held in the handle assembly 500. The trigger trigger 532 can be rotated between an unacted position and an acted position. The trigger trigger 532 can be moved to the unacted position by means of a spring or other propensity arrangement so that, when the physician releases the trigger trigger 532, the trigger trigger 532 can be rotated or otherwise , returned to the unacted position by means of the spring or the propensity In at least one way, the trigger trigger 532 can be positioned "far" from the closing trigger 512, as discussed above. As discussed in US Patent Application Publication 2015/0272575, the grip handle 500 can be equipped with a trigger trigger safety button to prevent the trigger trigger 532 from inadvertently operating. When the closing trigger 512 is in the unacted position, the safety button is contained in the handle assembly 500, where the doctor cannot readily access it and move it between a safety position, which prevents the trigger trigger 532 from operating and a position trigger in which trigger trigger 532 can be fired. When the physician presses the closing trigger 512, the safety button and trigger trigger 532 pivot downward, where they can then be manipulated by the physician.

[0161] In at least one form, the longitudinally movable drive member may have a toothed rack formed in it for engagement with a corresponding drive gear arrangement that interfaces with the motor. Additional details regarding those features can be found in US Patent Application Publication No. 2015/0272575. In at least one form, the handle assembly 500 also includes a manually actionable retraction assembly that is configured to enable the physician to manually retract the longitudinally movable driving member if the 505 motor is disabled. The rescue set can include a lever or rescue cable set that is stored inside the cable set 500 under a removable door 550. See Figure 2. The lever can be configured to be manually pivoted in ratchet engagement with the teeth on the drive member. In this way, the physician can manually retract drive member 540 using the retract handle assembly to engage drive member 540 in the proximal "PD" direction. US Patent No. 8,608,045, entitled

POWERED SURGICAL CUTTING AND STAPLING APPARATUS WITH MANUALLY RETRACTABLE FIRING SYSTEM, the description of which is hereby incorporated by reference in the present invention, reveals rescue provisions and other components, arrangements and systems that can also be used with any of the various surgical tool sets interchangeable materials disclosed in the present invention.

[0162] Turning now to Figures 3 and 4, the interchangeable surgical tool set 1000 includes a surgical end actuator 1500 comprising a first claw 1600 and a second claw 1800. In one arrangement, the first claw 1600 comprises an elongated channel 1602 which is configured to operationally support a surgical staple / clamp cartridge 1700 therein. The second claw 1800 comprises an anvil 1810 which is pivotally supported in relation to the elongated channel

1602. The interchangeable surgical tool set 1000 includes a hinge system 1300 comprising a hinge joint 1302 and a hinge lock 1400 (Figures 4 to 6), which can be configured to releasably secure the surgical end actuator 1500 in a desired articulated position in relation to a geometric axis of the drive axis SA1.

[0163] As can be seen in Figures 4 and 7-

9, the interchangeable surgical tool kit 1000 includes a tool frame assembly 1200 comprising a tool chassis 1210 that operationally supports a nozzle assembly 1240 therein.

In one form, the nose assembly 1240 is comprised of nozzle portions 1242, 1244 as well as an actuator wheel portion 1246 that is configured to be coupled to the assembled nozzle portions 1242, 1244 by pressure fittings, pins and / or screws, for example.

Interchangeable surgical tool set 1000 includes a proximal closure set 1900 that is operationally coupled to a distal closure set 2000 that is used to close and / or open anvil 1810 of surgical end actuator 1500 as will be further discussed in detail below .

In addition, the interchangeable surgical tool set 1000 includes a central column assembly 1250 that operationally supports the proximal closing assembly 1900 and is coupled to the surgical end actuator 1500. In various circumstances, to facilitate assembly, the central column assembly 1250 can be manufactured from an upper central column segment 1251 and a lower central column segment 1252 which are interconnected together by pressure fitting, adhesives and / or weld features, for example.

In assembled form, the center column assembly 1250 includes a proximal end 1253 which is pivotally supported on the tool frame 1210. In one arrangement, for example, the proximal end 1253 of the central column assembly 1250 is attached to a central column bearing (not shown) which is configured to be supported within the tool frame 1210. This arrangement facilitates the swivel attachment of the back 1250 to the tool frame 1210, so that the back 1250 can be selectively rotated around a geometric axis drive shaft SA1 in relation to the tool chassis 1210. In particular, in at least one arrangement, the proximal end 1253 of the center column assembly 1250 includes an upper pin location 1254 (Figures 4, 5, 7, 8 and 10) and a bottom pin location that are individually configured to receive a corresponding nozzle pin 1245 that extends inwardly from each of the portions the nozzle 1242, 1244, for example. This arrangement facilitates the rotation of the central column assembly 1250 around the geometric axis of the drive shaft SA1 by rotating the wheel portion of actuator 1246 of the nozzle assembly 1240.

[0164] As can be seen in Figures 4 and 5, the central column assembly 1250 additionally includes a segment of the drive shaft of the intermediate dorsum 1256 that has a diameter that is smaller than the diameter of the proximal end 1253 of the assembly center column 1250. The drive axis segment of the middle center column 1256 of the upper center column segment 1251 ends at an upper pin assembly feature 1260 and the drive axis segment of the middle center column of the lower center column segment 1252 ends in a lower pin assembly feature 1270. As can be seen in Figure 6, for example, the upper pin assembly feature 1260 is formed with a pin slot 1262 in it which is adapted to support mounting a top mount connection 1264 on it. Similarly, the lower pin assembly feature 1270 is formed with a pin slot 1272 in it which is adapted to support a lower assembly link 1274 in a passable manner. The upper mounting link 1264 includes a pivot socket 1266 inside it that is offset from the geometric axis of the drive axis SA1. The pivot socket 1266 is adapted to pivot a pivot pin 1634 on it which is formed in a channel cover or anvil retainer 1630 which is attached to a proximal end portion 1610 of the elongated channel 1602. The mono connection - lower pitch 1274 includes a lower pivot pin 1276 which is adapted to be received within a pivot hole 1611 formed in the proximal end portion 1610 of the elongated channel 1602. See Figure 6. The lower pivot pin 1276, as well as of the pivot hole 1611, it is displaced in relation to the geometric axis of the drive axis SA1. The lower pivot pin 1276 is vertically aligned with the pivot socket 1266 to define a pivot axis AA1 around which the surgical end actuator 1500 can pivot in relation to the geometric axis of the drive axis SA1. Although the pivot axis AA1 is transverse to the axis of the drive shaft SA1, the pivot axis AA1 is moved laterally from it and does not cross the axis of the drive shaft SA1.

[0165] Again with reference to Figures 6 and 15, the anvil 1810 includes an anvil body 1812 that ends at the anvil mounting portion 1820. The anvil mounting portion 1820 is movably supported or articulated in the elongated channel 1602 for selective pivoting displacement in relation to it around a fixed anvil pivot geometric axis PA1 (Figure 15) that is transversal to the geometric axis of the driving axis SA1. An anvil pivot member or rotating pin 1822 extends laterally outwardly on either side of the anvil mounting portion 1820 to be received on a corresponding rotating pin support 1614 formed on the vertical walls 1612 of the proximal end portion 1610 of the channel elongated 1602. The rotating pins of the anvil 1822 are pivotally retained in their corresponding rotating pin supports 1614 by the channel cover or anvil retainer 1630. The channel cover or anvil retainer 1630 includes a pair of fixing pins 1636 which are configured to be received retentively within the corresponding pin slots or notches 1616 formed in the vertical walls 1612 of the proximal end portion 1610 of the elongated channel 1602.

[0166] The surgical end actuator 1500 is selectively pivotal around the pivot axis AA1 by the pivot system 1300. In one form, the pivot system 1300 includes the proximal pivot actuator 1310 which is pivotally coupled to a connection pivot pin 1314. As can be seen in Figure 6, an offset pin 1314 is formed at a proximal end 1312 of the proximal pivot driver 1310. A pivot hole 1316 is formed at offset pin 1314 and is configured to receive pivotally a proximal link pin 1326 formed at the proximal end 1325 of the link link

1320. A distal end 1322 of the hinge link 1320 includes a pivot hole 1324 which is configured to pivotally receive within it a channel pin 1618 formed at the proximal end portion 1610 of the elongated channel 1602. Thus, the axial movement of the proximal articulation actuator 1310 will apply articulation movements to the elongated channel 1602 to articulate the surgical end actuator 1500 about the articulation axis AA1 in relation to the central column assembly 1250.

[0167] The movement of the anvil 1810 in relation to the elongated channel 1602 is effected by the axial movement of the set of the proximal closing system 1900 and the set of the distal closing system 2000. Now with reference to Figures 4 and 7, the closing set proximal ment 1900 comprises a proximal closing tube 1910 having a proximal closing tube portion 1920 and a distal portion 1930. The distal portion 1930 has a diameter that is smaller than the diameter of the proximal closing tube portion 1920. The proximal end 1922 of the proximal closing tube portion

1920 is pivotally supported on a reciprocating closing element 1940 that is slidably supported within the chassis of the 1210 tool, so that the reciprocating closing element 1940 can move axially in relation to the 1210 tool frame. , the reciprocating locking element 1940 includes a pair of proximally protruding hooks 1942 that are configured to be attached to the fixing pin 516 which is attached to the closing hinge assembly 514 of the handle assembly 500. A proximal end 1922 the portion of the proximal closing tube 1920 is pivotally coupled to the reciprocating closing element 1940. For example, a 1944 U-shaped connector is inserted into an annular slot 1924 in the portion of the proximal closing tube 1920 and is retained within the vertical slits 1946 in the reciprocating closing element 1940. This arrangement serves to fix the proximal closing member 1900 to the reciprocant element and closing 1940 for axial displacement with the same, while allowing the proximal closing member 1900 to rotate in relation to the reciprocating closing element 1940 around the geometric axis of the driving axis SA1. A closing spring 1948 (Figures 12-14) extends over the portion of the proximal closing tube 1920 to prop the reciprocating closing element 1940 in the proximal direction PD, which can serve to revolve the closing trigger 512 over the handle assembly 500 (Figure 2) to the unactivated position when the interchangeable surgical tool set 1000 is operationally coupled to the handle set 500.

[0168] Now with reference to Figures 5 and 6, a distal portion 1930 of the proximal closing tube 1910 is attached to the distal closing assembly 2000. The distal closing assembly 2000 includes a hinge connector 2010 that is coupled to a segment of distal closing tube 2030. The segment of the distal closing tube 2030 has a diameter that is larger than the diameter of the distal portion 1930 of the proximal closing tube 1910. The hinge connector 2010 has an end portion that extends proximally 2012 which is adapted to be received on a 1934 connection flange formed at the distal end of the distal portion 1930. The hinge connector 2010 can be retained on the 1934 connection flange by a suitable fastener arrangement, adhesive and / or welds, for example. The hinge connector 2010 includes the upper and lower protrusions 2014, 2016 that project distally from a distal end of the hinge connector 2010 that are movably coupled to a closing sleeve of the end actuator or pipe segment distal closure 2030. The segment of the distal closure tube 2030 includes an upper protrusion 2032 and a lower protrusion protruding proximally from a proximal end thereof. An upper double pivot link 2060 includes the proximal and distal pins that engage the corresponding holes 2015, 2034 in the upper latches 2014, 2032 of the hinge connector 2010 and the segment of the distal closing tube 2030, respectively. Similarly, a lower double pivot link 2064 includes proximal and distal pins 2065, 2066 that engage the corresponding holes 2019 in the lower latches 2016 of the hinge connector 2010 and the distal segment of the closing tube 2030, respectively. As will be discussed in more detail below, the distal and proximal axial translation of the proximal closing set 1900 and the distal closing set 2000 will result in the closing and opening of the anvil 1810 in relation to the elongated channel 1602.

[0169] The interchangeable surgical tool set 1000 additionally includes a trigger system commonly referred to as

2100. The firing system 2100 includes a firing member assembly 2110 that is supported for axial displacement within the center column assembly 1250. The firing member assembly 2110 includes a portion of the intermediate firing drive shaft 2120, which it is configured to be connected to a distal cutting portion or cutting bar 2130. The firing member assembly 2110 can also be referred to in the present invention as a "second drive shaft" and / or a "second drive shaft assembly ". As can be seen in Figure 5, the intermediate firing drive shaft portion 2120 may include a longitudinal slot 2124 at a distal end 2122 thereof, which can be configured to receive a proximal end 2132 of the cutter bar 2130. The slot longitudinal 2124 and the proximal end 2132 of the cutter bar 2130 are dimensioned and configured to allow relative movement between them and may comprise a sliding joint 2134. The sliding joint 2134 may allow the intermediate firing drive shaft portion 2120 of the firing member assembly 2110 is moved to articulate end actuator 1500 without moving, or at least substantially moving, the cutter bar

2130. Once the end actuator 1500 has been properly oriented, the portion of the intermediate firing drive shaft 2120 can be advanced distally until a proximal side wall of the longitudinal slot 2124 contacts a portion of the cutter bar 2130 in order to advance the cutter bar 2130 and fire the surgical staple / clamp cartridge 1700 positioned inside the elongated channel 1602. A proximal end 2127 of the intermediate firing drive shaft portion 2120 has a pin for fixing the firing drive shaft 2128 formed thereon (Figure 8) which is configured to be seated on a coupling base which is on the distal end of the longitudinally movable drive member of the drive system 530 within the handle assembly 500 This arrangement facilitates the axial movement of the portion of the intermediate firing drive shaft 2120 through the actuation of the driving system firing range 530.

[0170] In addition to the above, the interchangeable tool set 1000 can include a 2200 gear set, which can be configured to selectively and releasably couple the proximal articulation driver 1310 to the firing member 2100. In one form gear unit 2200 comprises a locking ring or locking sleeve 2210 positioned around the intermediate firing drive shaft portion 2120 of the firing system 2100, where locking sleeve 2210 can be rotated between a engaged position on the which locking sleeve 2210 couples the proximal pivoting actuator 1310 to the firing member 2110 and a disengaged position, where the proximal pivoting actuator 1310 is not operably coupled to the firing member 2110. When the glove locking device 2210 is in its engaged position, the distal movement of the firing member assembly 2110 can move the proximal articulation corresponding, the proximal movement of the firing member assembly 2110 can proximally move the proximal pivot trigger 1310. When the locking sleeve 2210 is in its disengaged position, the motion of the firing member assembly 2110 is not transmitted to the firing member. proximal joint 1310 and, as a result, the firing member assembly 2110 can move independently of the proximal joint driver 1310. In many circumstances, the proximal joint driver 1310 can be held in position by the joint lock 1400 when the 1310 proximal articulation trigger is not being moved proximally or distally by the trigger member assembly 2110.

[0171] The portion of the intermediate firing drive shaft 2120 of the firing member assembly 2110 is formed with two opposite flat sides 2121, 2123 with a driving notch 2126 formed thereon. See Figure 8. As can also be seen in Figure 13, locking sleeve 2210 comprises a cylindrical, or at least substantially cylindrical, body that includes a longitudinal opening 2212 that is configured to receive the portion of the intermediate firing drive shaft. 2120 through it. The locking sleeve 2210 comprises diametrically opposite and inward facing locking protrusions 2214, 2216 which, when the locking sleeve 2210 is in a position, are received in a hitching position within the corresponding portions of the drive notch 2126 in the portion of the intermediate firing drive shaft 2120 and, when in another position, are not received within the driving notch 2126 to thereby allow relative axial movement between the locking sleeve 2210 and the middle firing drive portion 2120 .

[0172] Now referring to Figures 8 and 12 to 14, locking sleeve 2210 additionally includes a locking member 2218 which is dimensioned to be movably received within a notch 1319 at a proximal end 1318 of the actuator proximal pivot 1310. Such an arrangement allows locking sleeve 2210 to rotate slightly in and out of engagement with the intermediate firing drive shaft portion 2120 while remaining in engagement with notch 1319 on proximal pivot driver 1310. For example , when the locking sleeve 2210 is in its engaged position, the locking protrusions 2214, 2216 are positioned inside a drive notch 2126 in the portion of the intermediate firing drive shaft 2120, so that a distal pushing force and / or a proximal pulling force can be transmitted from the firing member assembly 2110 to the locking sleeve 2210. Such a pulling or proximal pushing movement is then They are transmitted from the locking sleeve 2210 to the proximal articulation actuator 1310 in order to articulate the surgical end actuator 1500. In effect, the firing member assembly 2110, the locking sleeve 2210 and the proximal articulation actuator 1310 are will move together when locking sleeve 2210 is in its engaged (pivot) position. On the other hand, when the locking sleeve 1622 is in its disengaged position, the locking protrusions 2214, 2216 may not be received inside the drive notch 2126 in the portion of the intermediate trigger drive shaft 2120 and, as a result , a distal pushing force and / or a proximal pulling force may not be transmitted from the firing member assembly 2110 to the locking sleeve 2210 (and the proximal pivoting actuator 1310).

[0173] The relative movement of the locking sleeve 2210 between its engaged and disengaged positions can be controlled by the displacement assembly 2200 that interfaces with the proximal closing tube 1910 of the proximal closing assembly 1900. More specifically and with reference to Figures 8 and 9, the displacement assembly 2200 additionally includes a displacement key 2240 which is configured to be received slidingly within a key groove 2217 formed on the outer perimeter of the locking sleeve 2210. Such an arrangement allows the displacement key 2240 to move axially in with respect to locking sleeve 2210. Referring to Figures 8 to 11, the shifting key 2240 includes an actuator pin 2242 that extends through a cam slot or cam opening 1926 in the proximal closing tube portion 1920. See Figure 9. A cam surface 2243 is also provided adjacent actuator pin 2242 that is configured to interact in cam with the 1926 d cam opening and in order to cause the displacement key 2240 to rotate in response to axial movement of the proximal closing tube portion

1920.

[0174] The displacement assembly 2200 additionally includes a switching cylinder 2220 which is rotatably received at a proximal end portion of the proximal closing tube portion

1920. As can be seen in Figures 10 to 14, the actuator pin 2242 extends through an axial slot segment 2222 in the switching cylinder 2220 and is movably received within an arcuate slot segment 2224 in the switching cylinder 2220. The switch cylinder torsion spring 2226 (Figures 12 to 14) is mounted on the switch cylinder 2220 and engages the nozzle portion 1244 to apply a torsion or rotation inclination (arrow SR in Figures 10 and 11) used to turn the switching cylinder 2220 until the actuator pin 2242 reaches the end of the arcuate slot segment

2224. See Figures 11 and 12. When in this position, the switch cylinder 2220 can provide torsional polarization to the displacement key 2240, which in this way causes the lock sleeve 2210 to rotate to its engaged position with the intermediate firing drive axis 2120. This position also corresponds to the unactivated configuration of the proximal closing assembly 1900. In one arrangement, for example, the actuator pin 2242 is located in the upper portion of the cam opening 1926 in the pipe portion proximal closing 1920 when the proximal closing assembly 1900 is in an unacted configuration (anvil 1810 is in an open position spaced away from the 1700 surgical clamp / clamp cartridge). When in this position, actuation of the intermediate firing drive shaft portion 2120 will result in the axial movement of the proximal articulation actuator 1310. After the user has articulated the surgical end actuator 1500 to a desired orientation, the user can then activate the set proximal closing assembly 1900. The actuation of the proximal closing assembly 1900 will result in the distal displacement of the proximal closing tube portion 1920 to ultimately apply a closing movement to the anvil 1810. This distal displacement of the closing tube portion proximal 1920 will result in the opening of the cam 1926 interacting with the cam surface 2243 on the actuator pin 2242 to thereby cause the displacement switch 2240 to rotate the lock sleeve 2210 in an actuating direction AD. Such rotation of the locking sleeve 2210 will result in the disengagement of the latch protrusions 2214, 2216 of the drive notch 2126 in the portion of the intermediate trigger drive shaft 2120. When in such a configuration, the trigger drive system 530 can be actuated to drive the portion of the intermediate firing drive shaft 2120 without activating the proximal pivoting actuator 1310. Further details regarding the operation of the switching cylinder 2220 and locking sleeve 2210, as well as articulation and triggering arrangements Alternatives that can be employed with the various sets of interchangeable surgical tools described here, can be found in US Patent Application Serial No. 13 / 803.086, entitled ARTICULATABLE SURGICAL INSTRUMENT COMPRISING AN ARTICULATION LOCK, currently US Patent Application Publication No. 2014/0263541; and U.S. Patent Application Serial No. 15 / 019,196, entitled SURGICAL

INSTRUMENT ARTICULATION MECHANISM WITH SLOTTED SECONDARY CONSTRAINT, the descriptions of which are incorporated herein by reference into the present invention.

[0175] With reference again to Figures 8 to 13, the switching cylinder 2220 may additionally comprise at least partially circumferential openings 2228, 2230 defined therein, which can receive circumferential pins / assemblies 1245 extending from the nozzle portions 1242 , 1244 and allow relative rotation, but not translation, between the switching cylinder 2220 and the nozzle assembly 1240. The nozzle pins 1245 extend through corresponding openings 1923 in the portion of the proximal closing tube 1920 to be seated in locations of pins 1254 in the center column assembly 1250. See Figures 8 and 9. This arrangement allows the user to rotate the center column assembly 1250 around the geometric axis of the drive shaft by rotating the nozzle assembly 1240.

[0176] Also as shown in Figures 7 and 12-14, the interchangeable tool set 1000 can comprise a slide ring set 1230 that can be configured to conduct electrical energy to and / or from the surgical end actuator 1500 and / or transmit signals to and / or from the surgical end actuator 1500 back to a microprocessor 560 (Figure 2) on the handle set 500 or on the robotic system controller, for example. More details on the 1230 slip ring assembly and associated connectors can be found in US patent application Serial No. 13 / 803,086, currently ARTICULATABLE SURGICAL INSTRUMENT COMPRISING AN ARTICULATION LOCK, currently US Patent Application Publication No. 2014 / 0263541 and US Patent Application Serial No. 15 / 019,196, filed on February 9, 2016, entitled SURGICAL INSTRUMENT

ARTICULATION MECHANISM WITH SLOTTED SECONDARY CONSTRAINT, each of which is incorporated herein by reference in its respective totalities, as well as in U.S. Patent Application Serial No. 13 / 800.067 entitled STAPLE CARTRIDGE TISSUE THICKNESS SENSOR SYSTEM, currently Publication of

US Patent Application U.S. Patent Application Serial No. 2014/0263552, which is hereby incorporated by reference in its entirety. As also described in more detail in the aforementioned patent applications which have been incorporated herein, for reference, the interchangeable surgical tool set 1000 may also comprise at least one sensor which is configured to detect the position of the switch cylinder 2220.

[0177] Again with reference to Figure 2, the tool chassis 1210 includes at least one tapered clamping portion 1212 formed therein, which is adapted to be received inside a corresponding slot 507 formed inside the portion of the distal end of the handle structure 506 of the handle assembly 500. Various sets of interchangeable surgical tools employ a locking system 1220 to removably couple the interchangeable surgical tool assembly 1000 to the handle structure 506 of the handle assembly

500. In at least one form, as can be seen in Figure 7, the locking system 1220 includes a locking member or a locking fork 1222 which is movably coupled, for example, to the tool frame 1210. The fork locking device 1222 has a U-shape with two legs extending outwardly spaced 1223. Each of the legs 1223 has a pivot pin formed in them which is adapted to be received in the corresponding holes formed in the tool frame 1210. Such arrangement facilitates pivoting fixation of the locking fork 1222 to the tool chassis 1210. The locking fork 1222 can include two locking pins that project proximally 1224 that are configured to be released to the corresponding detent or locking grooves 509 at the distal end of the handle structure 506 of the handle assembly 500. See Figure 2. In many ways, the locking fork

1222 is propelled in the proximal direction by a spring or bias member 1225. The actuation of the locking fork 1222 can be done by a locking button 1226 which is slidably mounted on a set of the locking actuator 1221 which is mounted on the chassis tool 1210. The lock button 1226 can be moved in a proximal direction in relation to the lock fork 1222. The lock fork 1222 can be moved to an unlocked position by providing the lock button 1226 in the distal direction. it also causes the locking fork 1222 to rotate out of the retaining hitch with the distal end of the grip frame 506. When the locking fork 1222 is in "retaining latch" with the distal end of the grip frame 506 , the locking pins 1224 are seated with retention within the corresponding locking detents or grooves 509 at the distal end of the grip structure 506.

[0178] The locking fork 1222 includes at least one locking hook 1227 which is adapted to contact the corresponding locking pin portion 1943 that is formed in the reciprocating closing element 1940. When the reciprocating closing element 1940 is in a non-actuated position, the locking fork 1222 can be pivoted in a distal direction to unlock the interchangeable surgical tool set 1000 from the handle set

500. When in this position, the locking hooks 1227 do not come into contact with the locking pin portions 1943 on the reciprocating closing element 1940. However, when the reciprocating closing element 1940 moves to an actuated position, the locking fork 1222 is prevented from being pivoted to an unlocked position. In other words, if the doctor tried to rotate the locking fork 1222 to an unlocked position or, for example, if the locking fork 1222 was inadvertently collided or brought into contact in a way that could otherwise cause it to rotate distally, the locking hooks 1227 on the locking fork 1222 would come in contact with the locking pin portions 1943 on the reciprocating closing element 1940 and prevent the locking fork 1222 from moving to an unlocked position.

[0179] Still referring to Figure 6, the cutter bar 2130 may comprise a laminated beam structure that includes at least two layers of beam. Such beam layers may comprise, for example, stainless steel bands which are interconnected, for example, by welds and / or pins, for example, at the proximal ends and / or at other locations along the length thereof. In alternative modalities, the distal ends of the bands are not connected to allow the laminates or the bands to spread out in relation to each other when the end actuator is articulated. This arrangement allows the cutter bar 2130 to be sufficiently flexible to accommodate the articulation of the end actuator. Various laminated cutter bar provisions are presented in U.S. Patent Application Serial No. 15 / 019,245, entitled

SURGICAL INSTRUMENTS WITH CLOSURE STROKE REDUCTION ARRANGEMENTS, which is hereby incorporated by reference in its entirety. As can also be seen in Figure 6, a firing drive shaft support set 2300 is employed to provide lateral support to the cutter bar 2130 as it flexes to accommodate the articulation of the surgical end actuator 1500. More details regarding the operation of the firing drive axle support set 2300 and alternative cutter bar support arrangements can be found in US patent application No. 15 / 019.245, entitled SURGICAL INSTRUMENTS WITH CLOSURE STROKE REDUCTION ARRANGEMENTS and in US Patent Application n Serial No. 15 / 019.220, entitled SURGICAL INSTRUMENT WITH

ARTICULATING AND AXIALLY TRANSLATABLE END EFFECTOR, which are hereby incorporated by reference in their respective totalities.

[0180] As can also be seen in Figure 6, a firing member or cutting member 2140 is attached to the distal end of the cutting bar 2130. In an exemplary form, firing member 2140 comprises a body portion 2142 that supports a knife or fabric cutting portion 2144. The body portion 2142 projects through an elongated slot 1604 in the elongated channel 1602 and ends at a base member 2146 that extends laterally on each side of the body portion 2142. As measured whereas the firing member 2140 is driven distally through the surgical staple / fastener cartridge 1700, the base member 2146 moves within a passage in the elongate channel 1602 which is located under the surgical staple / fastener cartridge 1700. In one arrangement , the body portion 2142 includes two central flaps that project laterally 2145 that can move above the central passage inside the 1700 surgical clamp / clamp cartridge. See Figure 6. A by cutting section 2144 is disposed between a distally projecting top tip portion 2143 and the base member 2146. As can be seen further in Figure 6, the firing member 2140 may additionally include two top flaps, pins or anvil hitch features 2147 that extend laterally. As the firing member 2140 is driven distally, a top portion of the body portion 2142 extends through an anvil slit 1814 centrally arranged and the anvil engaging features 2147 slide over the corresponding anvil projections 1816 formed in each side of the anvil slit 1814. To facilitate the assembly of the anvil 1810 and the firing element 2140, in one arrangement, the top of the anvil body 1812 has an opening

1817 anyway. Once the anvil 1810 is mounted on the elongated channel 1602 and the firing element 2140 is installed, the opening 1817 is covered by an anvil cover 1819 which is fixed to the anvil body 1812 by welds and / or other suitable fixation means .

[0181] Again with reference to Figure 6, the trigger member 2140 is configured to interface operationally with a slide assembly 2150 that is operationally supported within a body 1702 of the staple cartridge / surgical clamps 1700. Slide assembly 2150 is displaceable slidingly into the staple cartridge body / surgical clamps 1702 from a proximal starting position adjacent to the proximal end 1704 of cartridge body 1702 to a final position adjacent to distal end 1706 of cartridge body 1702. Cartridge body 1702 operationally supports within it a plurality of clip drivers that are aligned in rows on each side of a centrally arranged slot 1708. The centrally arranged slot 1708 allows the trigger member 2140 to pass through it and cut the fabric that is between the anvil 1810 and the staple cartridge / surgical clamps 1700. The drivers are as associated with corresponding staple / fastener pockets 1712 that open across the upper platform surface 1710 of the cartridge body

1702. Each of the clamp actuators supports one or more clamps or surgical clamps on it. The slide assembly 2150 includes a plurality of inclined or wedge-shaped cams 2152 with each cam 2152 corresponding to a particular line of fasteners or drivers located on one side of the slot

1708.

[0182] To fix the interchangeable surgical tool set 1000 to the handle set 500, referred to in Figure 2, the doctor can position the tool frame 1210 of the interchangeable surgical tool set 1000 above or adjacent to the distal end of the handle structure 506 , so that the tapered fastening portions 1212 formed on the tool frame 1210 are aligned with the slot slots 507 in the grip structure

506. The physician can then move the interchangeable surgical tool set 1000 along an installation axis IA which is perpendicular to the drive axis SA to seat the tapered clamping portions 1212 in "operating engagement" with the corresponding receiving slots 507 at the distal end of the grip structure 506. In doing so, the firing pin fixing pin 2128 in the portion on the intermediate firing drive shaft 2120 will also be seated on the fixing support 542 on the longitudinally movable driving member in the handle assembly 500 and the fixing pin portions 516 in the closing connection 514 will be seated on the corresponding hooks 1942 in the reciprocating closing element 1940. As used in the present invention, the term "operational hitch" in reference to two components means that the two components are engaged with each other so that, by applying a movim When acting on them, the components perform their intended action, function and / or procedure.

[0183] During a typical surgical procedure, the doctor can introduce the surgical end actuator 1500 into the surgical site through a trocar or other opening in the patient to access the target tissue. In doing so, the physician aligns axially, or at least substantially, aligns the surgical end actuator 1500 in a non-articulated state along the geometric axis of the drive shaft and inserts the surgical end actuator 1500 through the trocar. Once the surgical end actuator 1500 has passed through the trocar, the physician may need to articulate the end actuator 1500 to advantageously position the end actuator 1500 adjacent to the target tissue. In addition to the above, the trigger drive system 530 is operated through a limited range of motion to move the hinge actuator 1310 and hinge the end actuator 1500. This hinge occurs before the anvil closes on the target tissue. Once the end actuator has reached the desired articulated position, the physician can then activate the closing drive system 510 to close the anvil 1810 on the target tissue. Such actuation of the closing drive system 510 activates the displacement assembly 2200 and detaches the articulation drive 1310 from the portion of the intermediate firing drive shaft 2120. Thus, once the target tissue has been properly captured in the surgical end actuator 1500, the physician can again activate the trigger drive system 530 to axially advance the trigger member 2140 through the staple cartridge / surgical clips 1700 to trigger the staples inward and cut the target tissue. Other closing and firing trigger arrangements, such as portable, manual, automated and / or robotic arrangements, for example, can be used to control the axial movement of the closure system components, the articulation system components and / or the components of the triggering system of the surgical tool set 1000.

[0184] An end actuator 10500 of a surgical instrument 10000 is illustrated in Figures 16 to 16B. The 10500 end actuator comprises a 10600 cartridge claw (Figure 18), including a 10700 staple cartridge and, in addition, an anvil 10800 configured to deform staples ejected from the staple cartridge 10700. In use, the anvil 10800 can be rotated between an open, unfixed position and a closed and secured position;

however, the 10600 cartridge gripper can be rotatable towards the anvil 10800 in other embodiments. The surgical instrument 10000 additionally comprises a drive shaft 10100 where the end actuator 10500 is pivotally connected to the drive shaft 10100 around a hinge joint 10200. In use, the end actuator 10500 is rotatable around the articulation joint 10200 between a fully articulated right position (Figure 16A), indicated by the angle ɵR, and a fully articulated left position (Figure 16B), indicated by the angle ɵL - and / or any suitable position between them. As discussed in more detail below, the ɵR and ɵL angles are limited by the design of the 10000 surgical instrument pivot trigger system. In at least one case, the ɵR and ɵL angles are limited to approximately 45 degrees from the non-articulated position. the 10500 end actuator (Figure 16).

[0185] Referring to Figure 18, the driving shaft 10100 of the surgical instrument 10000 comprises an outer closing tube that includes an outer housing 10110 that is movable distally to engage the anvil 10800 and move the anvil 10800 towards the cartridge of clamps 10700. The drive shaft 10100 additionally comprises a portion of the distal housing 10130 swiveled to the outer housing 10110 by two connector plates 10120 positioned on opposite sides of the hinge joint 10200. Each connector plate 10120 is connected to the housing outer 10110 on a pivot 10115 and, similarly, to the portion of the distal housing 10130 on a pivot 10125. Connector plates 10120 allow the closing tube to slide in relation to the pivot joint 10200 when end actuator 10500 is in a hinged position and, as a result, the anvil 10800 can be opened and closed while the end actuator 10500 is in a position the articulated. In addition to the above, the distal housing 10130 comprises an opening defined there configured to receive a flap extending from the proximal end of the anvil 10800 - the side wall of which is configured to engage the flap and transfer a proximal or opening movement, from the closing tube to the 10800 anvil.

[0186] An end actuator 11500 of an 11000 surgical instrument is illustrated in Figures 17 to 17B. The 11500 end actuator comprises a 11600 cartridge gripper (Figure 19), including a 11700 staple cartridge and, in addition, an 11800 anvil configured to deform staples ejected from the 11700 staple cartridge. In use, the 11800 anvil it can be rotated between an open position, not fixed and a closed and fixed position; however, arrangements are made in which the cartridge claw 11600 is movable in relation to the anvil 11800. The surgical instrument 11000 additionally comprises a drive shaft 11100 in which the end actuator 11500 is pivotally connected to the drive shaft 11100 to the around an articulation joint 11200. In use, the 11500 end actuator is rotatable around the articulation joint 11200 between a fully articulated right position (Figure 17A), indicated by the αR angle, and a fully articulated left position (Figure 17B ), indicated by the angle αL - and / or any suitable position between them. Although the αR and αL angles are ultimately limited by the design of the 11000 surgical instrument hinge trigger system, the αR and αL angles are larger. In at least one case, the angles αR and αL are approximately 60 degrees in relation to the non-articulated position of the 11500 end actuator (Figure 17), for example.

[0187] Referring to Figure 19, the drive shaft 11100 of the surgical instrument 11000 comprises an external closing tube that includes an external housing 11110 which is movable distally to engage the 11800 anvil and move the 11800 anvil towards the cartridge clamp 11700. The drive shaft 11100 additionally comprises a distal housing 11130 swiveled to the outer housing 11110 by two connector plates 11120 positioned on opposite sides of the hinge joint 11200. Each connector plate 11120 is connected to the outer housing 11110 in one pivot 11115 and, similarly, to the distal housing 11130 in a pivot 11125. Similar to the above, connector plates 11120 allow the closing tube to slide in relation to the hinge joint 11200 when the end actuator 11500 is in a position articulated in which, as a result, the anvil 11800 can be opened and closed while the end actuator 11500 is in u articulated position. In addition to the above, the distal housing 11130 comprises an opening defined there configured to receive a flap extending from the proximal end of the anvil 11800 - whose side wall is configured to engage the flap and transfer a proximal movement, or opening, from the closing tube to the 11800 anvil.

[0188] Again with reference to Figure 18, the surgical instrument 10000 additionally comprises a hinge actuator system 10300 that includes a hinge actuator actuator 10310 that extends through an inner opening 10105 defined in the closing tube 10110 of the drive shaft 10100. The hinged actuator actuator 10310 comprises a distal end operatively engaged with the jaw of the 10600 end actuator cartridge 105. More specifically, the distal end of the hinged actuator actuator 10310 comprises an opening, or slot, 10320 defined therein, and the 10600 cartridge jaw comprises a pin 10620 that extends into the slot

10320. When the hinge actuator actuator 10310 is pushed distally, the end actuator 10500 is driven to the right (Figure 16A) around a fixed geometry axis defined by a pivot 10210 that swivelly connects the claw of the 10600 cartridge to a drive shaft structure 10100. Correspondingly, end actuator 10500 is rotated to the left (Figure 16B) around pivot 10210 when hinge actuator actuator 10310 is pulled proximally.

[0189] Again with reference to Figure 19, surgical instrument 11000 additionally comprises a hinge actuator system 11300 that includes a hinge actuator 11310 that extends through an inner opening 11105 defined in closure tube 11110. The system hinge actuator 11300 additionally comprises a hinge connection 11320 pivotally coupled to a distal end of the hinge actuator 11310 around a pin 11315. Similarly, hinge connection 11320 is pivotally coupled to the gripper of the 11600 cartridge around a drive pin 11620 that extends through an opening defined in the hinge connection 11320. When the hinge actuator 11310 is pushed distally, the end actuator 11500 is driven to the right (Figure 17A ) around a fixed geometric axis defined by a 11210 pivot that swivelly connects the card claw ucho 11600 to a drive shaft structure 11100. Correspondingly, end actuator 11500 is rotated to the left (Figure 17B) around pivot 11210 when hinge actuator actuator 11310 is pulled proximally.

[0190] In addition to the above, the hinge connection 11320 of the hinge system 11300 allows the end actuator 11500 to be hinged over a wider range of hinge angles than the end actuator 10500 for a given, or equal, stroke length of joint actuators 10310 and 11310. A side-by-side comparison of end actuators 10500 and 11500 is provided in Figures 20 and 21 illustrating end actuators 10500 and 11500 in their fully articulated configurations on the right - and also illustrating that the 11500 end actuator can be further hinged to the right than the 10500 end actuator. A similar comparison can be made showing the 10500 and 11500 end actuators in their fully hinged configurations on the left. In addition, Figure 22 represents the entire articulation range of the 10500 end actuator while Figure 23 represents the entire articulation range of the 11500 end actuator.

[0191] Again with reference to Figure 22, the articulation actuator 10310 of the surgical instrument 10000 is advanced by a distal stroke length (DSL) in relation to its non-articulated position to fully articulate the end actuator 10500 to the right. Correspondingly, the articulation actuator 10310 is retracted to a proximal stroke length (PSL) in relation to its non-articulated position to fully articulate the end actuator 10500 to the left. The distal stroke length (DSL) and the proximal stroke length (PSL) of the 10310 hinge actuator are the same, or at least substantially the same. Now referring to Figure 23, the 10310 pivot actuator is advanced by a distal stroke length (DSL) relative to its non-pivoted position to fully pivot the 11500 end actuator to the right. Correspondingly, the 11310 pivot actuator is retracted to a proximal stroke length (PSL) in relation to its non-pivoted position to fully pivot the 11500 end actuator to the left. The distal stroke length (DSL) and proximal stroke length (PSL) of the 11310 joint actuator are not the same - the distal stroke length (DSL) is shorter than the proximal stroke length (PSL instead) ). In other embodiments, the proximal stroke length (DSL) is shorter than the distal stroke length (PSL). In any case, now with reference to Figures 31 to 31B, the combination of proximal stroke length (PSL) and distal stroke length (DSL) is equal to the entire stroke length (SL).

[0192] In addition to the above, joint actuator 10310 is configured to torque the first claw 10600 of end actuator 10500 through pin 10620 to rotate end actuator 10500 around joint joint 10200. Again with reference In Figure 22, a lateral torque arm defined between pivot joint 10210 of articulation joint 10200 and pin 10620 has a length TAC1 when end actuator 10500 is in its non-articulated position. The length TAC1 is measured in an orthogonal direction with respect to a longitudinal geometric axis 10190 that extends through the joint pivot joint 10210. Similarly, the lateral torque arm defined between joint joint 10210 and pin 10620 has a length TAR1 when the end actuator 10500 is fully pivoted to the right and similarly a length TAL1 when the end actuator 10500 is fully pivoted to the left - both lengths are measured orthogonally to the geometric axis longitudinal 10190. Notably, the lengths TAR1 and TAL1, and the torque arms they define, are the same, or at least substantially the same. In addition, the lengths TAR1 and TAL1 are smaller than the length of the non-articulated lateral torque arm TAC1. In this way, the largest torque arm, or mechanical advantage, of the 10300 articulation system exists when the end actuator 10500 is in its non-articulated position.

[0193] In at least one case, the length of the TAC1 arm is approximately 0.180 ", the length of the TAR1 arm is approximately 0.130" and the length of the TAL1 arm is approximately 0.130 ", for example.

[0194] In addition to the above, the 11310 hinge actuator of the surgical instrument 11000 is configured to torque the first claw 11600 of the end actuator 11500 through pin 11620 to rotate the end actuator 11500 around the hinge joint 11200 Referring to Figures 23, 28 and 30, a lateral torque arm (LTA) defined between the pivot joint 11210 of the articulation joint 11200 and the pin 11620 is defined by a length TAC2 when the end actuator 11500 is in its non-articulated position. The length TAC2 is measured in an orthogonal direction with respect to a longitudinal axis 11190 that extends through the joint pivot joint 11210. Notably, the longitudinal axis 11190 is offset and parallel to the center line of the drive shaft 11100 , as discussed in greater detail below in connection with Figure 25. Similar to the above, the lateral torque arm defined between joint 11210 and pin 11620 is defined by a length TAR2 when end actuator 11500 it is completely articulated to the right (Figure 30A) and, similarly, a TAL2 length when the end actuator 11500 is completely articulated to the left (Figure 30B) - both lengths are measured orthogonally in relation to the longitudinal geometric axis

11190. Notably, the TAR2 length is greater than the length of the non-articulated lateral torque arm TAC1 and the length TAL2 is shorter than the length of the non-articulated lateral torque arm

TAC1. In addition, the lengths TAR2 and TAL2, and the torque arms they define, are not the same. Instead, the length of the torque arm to the right TAR2 is considerably longer than the length of the torque arm to the left TAL2. In fact, the length of the torque arm articulated to the right TAR2 and the length of the torque arm articulated to the left TAL2 extend in different directions. Such an arrangement provides a greater pushing torque arm compared to a smaller pulling torque arm. In several cases, as a result, the retract pull force applied by the 11310 hinge actuator to pivot the end actuator 11500 to the left (Figure 30B) may be, or may need to be, greater than the distal push force for articulate end actuator 11500 to the right (Figures 29 and 30A). Advantageously, the 11310 pivot actuator can accommodate such greater pulling force as the 11310 pivot actuator is not subject to warping failure when being pulled.

[0195] In at least one case, the length of the TAC2 arm is approximately 0.149 ", the TAR2 length is approximately 0.154" and the length of the TAL2 arm is approximately 0.015 ", for example.

[0196] In addition to the above, the 11000 surgical instrument is configured and arranged to provide a large torque to the 11500 end actuator while, at the same time, providing a wide range of articulation, or sweeping, in response to a short articulation stroke . Namely, several design reasons for these relationships can be established and used to design the surgical instrument

11000. For example, a first ratio comprises the length of the fully articulated torque arm to the right (TA) divided by the length of the complete articulation stroke (SL) of the 11310 articulation actuator. The value of this first ratio is dimensionless. In at least one case, the torque arm fully articulated to the right (TA) measures 0.154 "and the length of the complete articulation stroke (SL) measures 0.275", resulting in a ratio value of 0.56, for example. Higher ratio values for the first ratio indicate more efficient articulation systems. In many cases, the value for the first ratio is less than 1.0, but it can be greater than 1.0. In at least one case, the fully articulated torque arm to the right (TA) measures 2.79 cm and the length of the complete articulation stroke (SL) measures 11.43 mm, resulting in a ratio value of 0.24 , for example.

[0197] The examples provided above for the first reason were based on the length of the torque arm (TA) when the end actuator 11500 is in its fully pivoted position to the right. This specific position of the 11500 end actuator is notable because the 11310 hinge actuator is compressed and can buckle when the load transmitted through it is excessive. That said, the first reason could also be used to analyze any suitable position of the 11500 end actuator, such as its non-articulated position and its completely articulated to the left, for example. In at least one case, the length of the non-articulated torque arm (TA) is 6.17 mm, resulting in a ratio value of 0.54 for a stroke length (SL) of 11.43 mm, for example. In addition, in at least one case, the length of the fully articulated torque arm to the left (TA) is 1.41 mm, resulting in a ratio value of 0.12 for a stroke length (SL) of 11, 43 mm, for example.

[0198] A second reason includes the arc length at which the drive pin 11620 is swept when the end actuator 11500 is pivoted between its fully pivoted position to the right and its fully pivoted position to the left, that is, its length scanning arc (ALS). More specifically, the second ratio comprises the sweeping arc length (ALS) of the drive pin 11620 divided by the length of the complete articulation stroke (SL) of the 11310 articulation actuator. The value of this second ratio is dimensionless. In at least one case, the length of the scanning arm (ALS) of the drive pin 11620 is 0.387 "and the length of the complete articulation stroke (SL) is 0.275", resulting in a ratio value of 1.41 , for example. In at least one case, the length of the scanning arc (ALS) measures 0.444 "and the length of the complete articulation stroke (SL) measures 0.306", resulting in a ratio value of 1.45, for example. In at least one case, the length of the scanning arc (ALS) measures 12.94 mm and the length of the complete articulation stroke (SL) measures 11.43 mm, resulting in a ratio value of 1.13, for example . Higher ratio values for the second ratio indicate more efficient articulation systems. In several cases, the value for the second ratio is greater than 1.0, such as between 1.0 and 3.0, for example. In at least one case, the second ratio value is approximately 2.0, for example. In certain cases, the value for the second ratio is about 1.1, but between 0.9 and 1.3, for example.

[0199] A third reason comprises the sum of the length of the torque arm fully articulated to the right (TA) and the length of the sweeping arc (ALS) of the drive pin 11620 divided by the length of the complete articulation stroke (SL). The value of this third reason is dimensionless. In at least one case, the length of the torque arm articulated completely to the right (TA) is 0.154 ", the length of the sweeping arc (ALS) of the drive pin 11620 is 0.387" and the length of the articulation stroke (SL) is 0.275 ", resulting in a ratio value of 1.97,

for example. In at least one case, the length of the torque arm fully articulated to the right (TA) is 2.79 mm, the length of the scanning arm (ALS) of the drive pin 11620 is 12.94 mm and the length of the stroke complete articulation (SL) is 11.43 mm, resulting in a ratio value of 1.38, for example. Higher ratio values for the third ratio indicate more efficient articulation systems. In several cases, the value for the third ratio is greater than 1.0, such as between 1.0 and 3.0, for example. In at least one case, the third ratio value is approximately 2.0 or greater than 2.0, for example.

[0200] Similar to the above, the third reason could be used to evaluate the articulation system when the 11500 end actuator is in any suitable position, such as in its non-articulated and fully articulated positions to the left, for example .

[0201] A fourth reason comprises the product of the length of the torque arm fully articulated to the right (TA) and the length of the sweeping arc (ALS) of the drive pin 11620 divided by the length of the complete articulation stroke (SL). The value of this fourth reason is not dimensionless and is instead measured at a distance. In at least one case, the length of the torque arm fully articulated to the right (TA) is 0.154 ", the length of the sweeping arc (ALS) of the drive pin 11620 is 0.387" and the length of the complete articulation stroke ( SL) is 0.275 ", resulting in a ratio value of 0.217", for example. This value can be dimensionless by dividing it by the stroke length (SL) again, resulting in a value of 0.79. In at least one case, the torque arm length fully articulated to the right (TA) is 2.79 mm, the scan arm length (ALS) of the 11620 drive pin is 12.94 mm and the length the complete articulation stroke (SL) is 11.43 mm, resulting in a ratio value of 3.15 mm, for example. In certain cases, the value for the fourth ratio is about 3.1 mm, but between 0.9 mm and 5.4 mm, for example. Similar to the above, this value can be dimensionless by dividing it by the stroke length (SL) again, resulting in a value of 0.28. Higher ratio values for the fourth ratio indicate more efficient articulation systems.

[0202] Similar to the above, the fourth reason could be used to evaluate the articulation system when the 11500 end actuator is in any suitable position, such as in its non-articulated and fully articulated positions to the left, for example .

[0203] As discussed above, end actuator 11500 is pivotally mounted to the drive shaft 11100 around a fixed pivot 11210 of the articulation joint 11200. Now with reference to Figures 24 and 25, the drive shaft 11100 comprises - end 11220 distal mounting tabs that extend from and are fixedly mounted to the structure, or central column, of the 11100 drive shaft. A first distal 11220 mounting tab is mounted on the first claw 11600, which comprises a frame portion bottom, and a second distal mounting tab 11220 is mounted on an upper frame portion 11230. The interconnection between the mounting tabs 11220 and the first jaw 11600 and the upper frame portion 11230 defines the fixed pivot 11210. As is also discussed above, the pivot of the fixed axis 11210 is laterally displaced with respect to a central longitudinal geometry axis LA of the drive axis 11100 by a travel distance OD. In at least one case, the fixed axis pivot 11210 is laterally displaced by approximately 0.036 ", for example. In addition, with reference to Figures 28 to 30B, pin 11620 is longitudinally displaced in relation to the fixed pivot 11210 which creates an arm of longitudinal or axial torque (ATA).

[0204] As discussed above, the 11100 drive shaft closure tube is movable distally to engage the 11800 anvil jaw of the 11500 end actuator and move the 11800 anvil jaw towards a 11700 staple cartridge positioned 11600 cartridge gripper. In other words, the closing tube is configured to move the 11800 anvil from an open position (Figures 26 to 26B) to a closed position (Figures 27 to 27B) to secure a patient's tissue against the staple cartridge

11700. In such cases, the closing tube, which comprises housing 11110, connector plates 11120 and distal housing 11130 slide distally from the hinge joint 11200 during a closing stroke. When the end actuator 11500 is in an open, non-articulated configuration, now with reference to Figure 26, the connector plates 11120 extend in a direction that is slightly transverse to the central longitudinal axis LA of the drive shaft 11100. More specifically, a CA geometry axis extending between joints 11115 and 11125 is slightly transverse to the longitudinal geometry LA of drive axis 11100 when end actuator 11500 is in an open, non-articulated configuration. When the 11500 end actuator is pivoted in relation to the right (Figure 26A) or to the right (Figure 26B), the orientation of the CA axis in relation to the central longitudinal axis LA may change.

[0205] In several cases, in addition to the above, the orientation of the CA axis will change in relation to a longitudinal axis that extends between the proximal end and the distal end of the 11500 end actuator. In at least one In this case, the AC axis is transversal to such a axis of the longitudinal end actuator, except in a configuration in which the AC axis will be parallel to the geometric axis of the longitudinal end actuator.

[0206] In addition to the above, the orientation of an AA geometry axis defined between the pivot pivot 11210 and the distal pivot 11125 of the 11120 connector plates changes as the end actuator 11500 is pivoted. With reference to Figure 26, the geometric axis AA extends at an angle β with respect to the geometric axis AC when the end actuator 11500 is in an open, non-articulated configuration. When the 11500 end actuator is pivoted in an open configuration on the right (Figure 26A), the angle β decreases. When the 11500 end actuator is hinged in an open configuration on the left (Figure 26B), the angle β increases. At no time, however, the AA axis is collinear with or parallel to the CA axis when the 11500 open end actuator is pivoted. Instead, the AA axis is transverse to the CA axis when the end actuator 11500 is pivoted in an open configuration.

[0207] With reference to Figure 27, the AA axis extends at an angle γ to the CA axis when the end actuator 11500 is in a closed, non-articulated configuration. When the 11500 end actuator is pivoted in a closed configuration to the right (Figure 27A), the angle γ increases. When the 11500 end actuator is hinged in a closed configuration to the left (Figure 27B), the δ angle increases. At no time, however, is the AA axis aligned with the CA axis when the 11500 end actuator is articulated in a closed configuration, and / or any other configuration between an open configuration and a closed configuration. Instead, the geometric axis AA is transversal to the geometric axis AC when the end actuator 11500 is articulated in a closed configuration and / or in any other configuration between an open configuration and a closed configuration.

[0208] Again with reference to Figures 20 and 21, the design of the surgical instrument 11000 can shorten the end actuator 11500 compared to the end actuator 10500. In addition, the distance between the joint joint 10200 and the proximal end of the staple line that is applied to a patient's tissue by the end actuator 10500 is an L1 distance - while the distance between the hinge joint 11200 and the proximal end of the staple line that is applied by the 11500 end actuator is an L2 distance , which is shorter than the distance L1.

[0209] Now with reference to Figures 40 to 45, surgical instrument 11000 additionally comprises a hinge lock 11400 configured to selectively lock the hinge actuator system 11300 and end actuator 11500 in position. The hinge lock 11400 comprises a distal end 11402 mounted on a frame 11180 of the drive shaft 11100. More particularly, the frame of the drive shaft 11180 comprises pins, or projections, 11182 received and / or pressed closely into the openings defined at the distal end 11402. The hinge lock 11400 additionally comprises a proximal end 11404 configured to move with respect to the distal end

11402. In at least one aspect, hinge lock 11400 comprises a cantilever bundle where the distal end 11402 comprises a fixed end and the proximal end 11404 comprises a free end. The proximal end 11404 is positioned in a cavity 11184 defined in the drive shaft structure 11180 and is configured to move laterally in and in the opposite direction to the hinge actuator actuator

11310, as described in more detail below.

[0210] In addition to the above, the proximal end 11404 of the hinge lock 11400 comprises one or more teeth 11406 defined therein that are configured to engage the hinge actuator actuator 11310. As shown in Figure 40, teeth 11406 are arranged in a longitudinal matrix; however, any suitable arrangement can be used. The actuator of the hinge actuator 11310 comprises a longitudinal tooth array 11316 defined therein which is configured to be engaged by the hinge lock teeth 11406. Referring to Figure 41, the structure of the drive shaft 11180 additionally comprises a tooth array longitudinal 11186 defined in the same that is configured to be engaged by the articulation lock teeth

11406. When hinge lock 11400 is in a fully locked state, as described in greater detail below, hinge lock teeth 11406 are engaged with the teeth of the 11316 actuator actuator and the teeth of the drive shaft structure 11186, so that hinge lock 11400 locks hinge actuator 11310 into the drive shaft structure 11180 and prevents, or at least inhibits, the relative movement between the hinge actuator 11310 and the drive shaft structure 11180.

[0211] In addition to the above, hinge lock 11400 is configurable in three states - a self-locked state, an unlocked state, and a fully locked state. When pivot lock 11400 is in a self-locking state, with reference to Figure 43, pivot lock teeth 11406 11400 are engaged with the teeth of the 11316 actuator actuator and the teeth of the drive shaft structure 11186. In such cases , hinge lock 11400 can withstand some force transmitted through the hinge actuator 11310 actuator; However, the proximal and / or distal movement of the 11310 hinge actuator actuator can overcome the clamping force of the hinge lock 11400 and move the hinge lock 11400 to its unlocked configuration, as shown in Figure 44. In such cases , hinge lock 11400 can flex or deflect laterally in the direction opposite to actuator actuator 11310. Hinge lock 11400 comprises a spring element 11403 that extends between distal portion 11402 and proximal portion 11404 that is configured to resiliently return , or at least tilt, the articulation lock towards its self-locked configuration (Figure 42). As a result, the 11300 pivot drive system can lock and unlock itself even as a result of its own movement and pivot end actuator 11500, unless pivot lock 11400 is placed in its fully locked position, as discussed below.

[0212] As discussed further above, the drive shaft 11100 of the surgical instrument 11000 comprises a closing tube 11110 which is advanced distally during a closing stroke to close the 11500 end actuator. Before the closing stroke, the lock pivot 11400 is movable between its self-locking and unlocked configurations to allow the 11500 end actuator to be pivoted by the 11300 pivot drive system. However, during the closing stroke, the closing tube 11110 is configured to engage the hinge 11400 and place or secure hinge lock 11400 in its fully locked configuration. More specifically, the closure tube 11110 comprises a projection, or flap, 11118 configured to engage a cam surface 11408 defined on the rear side of the joint lock 11400 and prevent the teeth of the joint lock 11406 from separating from the teeth. of the 11316 actuator actuator and the teeth of the drive shaft structure

11186. When closing tube 11110 is retracted proximally to open end actuator 11500, flap 11118 disengages from hinge lock 11400 and hinge lock 11400 is free to move between its self-locked and unlocked positions, as discussed above , so that the 11500 end actuator can be pivoted once again.

[0213] The surgical instrument 11000 described above is further illustrated in figures 80 to 82. The surgical instrument 11000 comprises a drive shaft 11100 that is configured for use with a trocar that has a defined passage in it. The drive shaft of the surgical instrument 11100 comprises different diameters at different points along the length of the drive shaft of the surgical instrument 11100. Among other things, the drive shaft of the surgical instrument 11100 comprises a central region 11160 that comprises a diameter smaller than any other region of the 11000 surgical instrument's drive shaft. This 11100 surgical instrument's drive shaft geometry provides significant advantages over previous designs and solves a long-standing problem associated with the use of a trocar. Typically, when a surgical instrument is used in combination with a trocar during a surgical procedure, the surgical procedure is limited by the range of angles that the instrument can assume as a result of the constraints created by the passage of the trocar. The drive shaft configuration of the 11100 surgical instrument is an improvement over the existing drive shaft configurations because it increases the range of angles that a surgical instrument can assume in relation to the longitudinal geometric axis of a trocar. As a result, the user of the 11000 surgical instrument can manipulate the 11000 surgical instrument at a variety of angles in relation to the longitudinal geometric axis of the trocar due to the smaller diameter of the central region 11160 of the 11100 surgical instrument drive axis.

[0214] Referring to Figures 80 and 81, the driving axis of the surgical instrument 11100 additionally comprises a proximal region 11150 and a distal region 11170. The proximal region 11150 of the driving axis of the surgical instrument 11000 is located adjacent to a set nozzle 11140 of the drive shaft 11100. The distal region 11170 is located closest to the end actuator 11500. The proximal region 11150 of the drive shaft of the surgical instrument comprises a first diameter, and the central region 11160 comprises a second diameter. The distal region 11170 further comprises a third diameter. The first diameter of the proximal region 11150 is different from the second diameter of the central region 11160. Similarly, the second diameter of the central region 11160 is different from the third diameter of the distal region 11170. The first diameter of the proximal region 11150 is different from the third diameter distal region 11170; however, modalities are contemplated in which the first diameter and the third diameter are the same.

[0215] In addition to the above, the proximal region 11150 defines a central longitudinal geometric axis. The central region 11160 extends along the longitudinal geometric axis and is centered in relation to the central longitudinal geometric axis. Each of the proximal region 11150 and central region 11160 define a circular profile, although they can comprise any suitable configuration. The distal region 11170 is not centered in relation to the central longitudinal geometric axis. Instead, the distal region 11170 is displaced laterally with respect to the central longitudinal geometric axis. In addition, more of the cross section and / or perimeter of the distal region 11170 is positioned on a first side of the central longitudinal geometric axis than a second side. In at least one example, the distal region 11170 comprises an enlargement that extends to one side of the central longitudinal axis. In addition, the 11170 distal region does not define a circular profile.

[0216] Still with reference to Figures 80 and 81, the central region 11160 comprises a second width that is smaller than the first width of the proximal region 11150. The central region additionally comprises a second width that is smaller than the third width of the distal region 11170. The proximal region 11150 additionally comprises a different width than the width of the distal region 11170. For example, the width of the proximal region 11150 is less than the width of the distal region 11170, but it is even greater than the width from the central region

11160. Similarly, the width of the proximal region 11150 is greater than the width of the distal region 11170 and the width of the central region 11160. In other cases, the proximal region 11150 and the distal region 11170 comprise approximately the same width.

[0217] With reference to Figures 80 to 82, the drive axis of the surgical instrument 11100 of the surgical instrument 11000 is configured, for example, to fit through a 12 mm trocar. In at least one such case, the central region 11160 of the driving axis of the surgical instrument 11100 comprises a maximum diameter of approximately 9 mm. Such a diameter of the central region 11160 provides a wider range of angles that the drive axis 11100 can assume in relation to the center line of the trocar. In addition, such an arrangement may reduce the possibility of causing damage to the intercostal nerves associated with placing the 11100 surgical instrument drive shaft between a patient's ribs during certain surgical procedures. The 11170 distal region of the 11100 surgical instrument drive shaft is configured to fit through a 12 mm trocar, and comprises one or more 11172 flat sides to provide an increased level of access during procedures requiring a high level articulation. Other modalities are provided in which the 11100 drive shaft is inserted through an 8 mm trocar and / or a 5 mm trocar, for example.

[0218] The 11150 proximal region comprises a scaled or tapered region, close to the proximal end of the 11100 surgical instrument drive axis, where the 11100 surgical instrument drive axis translates from the 11150 proximal region to the central region 11160. The 11160 central region additionally comprises a stepped, or tapered region, close to the distal end of the 11100 surgical instrument drive axis, where the 11100 surgical instrument drive axis transitions from the 11160 central region to the 11170 distal region.

[0219] Still with reference to Figures 80 and 81, the proximal region 11150 comprises a first circumference, the central region 11160 comprises a second circumference and the distal region 11170 comprises a third circumference. The circumference of the proximal region 11150 is different from the circumference of the central region 11160, due to the difference in diameters of such portions of the driving axis of the surgical instrument 11100. Similarly, the circumference of the central region 11160 and the circumference of the distal region 11170 are different. The circumference of the proximal region 11150 and the circumference of the distal region 11170 are the same, but may be different in other modalities.

[0220] Again with reference to Figures 80 and 81, the drive shaft of the surgical instrument 11100 comprises a single piece of material formed, although the drive shaft of the surgical instrument 11100 can comprise multiple pieces of material that are combined to form a single drive shaft of the cohesive surgical instrument, in other cases. The pieces of material can be assembled using any suitable process. The drive shaft of the 11100 surgical instrument is configured to operate with a variety of surgical arrangements not limited to the surgical stapling instruments described above. The drive shaft of the 11100 surgical instrument can be used with other surgical instruments that have swiveling end actuators. Other surgical instruments can include, for example, ultrasonic surgical devices, clip applicators and fastener applicators. In addition, the drive shaft of the 11100 surgical instrument is configured to be used with any surgical instrument where the use of a trocar passage is appropriate.

[0221] In addition to the above, the outer tube 11110 of the drive shaft 11100 comprises a proximal end 11150 and a longitudinal portion 11160 comprising a diameter, or width, which is narrower than the diameter, or width, of the proximal end 11150. That said, the 11000 surgical instrument is configured and arranged to provide a high torque for the 11500 end actuator while, at the same time, the longitudinal portion 11160 comprises a narrow diameter. Namely, at least one design ratio for this relationship can be established and used to design the 11000 surgical instrument. For example, a ratio comprises the diameter of the longitudinal portion 11160 (D) divided by the length of the fully articulated torque arm for the right (TA). The value of this ratio is dimensionless. In at least one case, the diameter of the longitudinal portion 11160 (D) is 0.316 "and the length of the torque arm (TA) is 0.154", resulting in a ratio value of 2.06, for example. Lower values for this ratio indicate more efficient articulation systems. In many cases, the value for this ratio is less than 2.0, such as between 1.0 and 2.0, for example. In at least one case, the ratio value is between 2.0 and 3.0, for example. In certain cases, the ratio value is less than 3.38, for example.

[0222] In addition to the above, the outer tube 11110 of the drive shaft 11100 includes a longitudinal portion 11160 and an enlarged distal end 11170 (Figure 80). Again with reference to Figure 40, the entire articulation lock 11400 is positioned in the longitudinal portion 11160 and not in the enlarged distal end 11170. However, modalities are provided in which at least a portion of the articulation lock 11400 is positioned in the enlarged distal end. 11170. In at least one of these Cases, hinge lock 11400 is mounted on the drive shaft structure so that the distal end 11402 of hinge lock 11400 is at the increased distal end 11170 of the outer tube

11110. In certain cases, the hinge lock 11400 is again arranged so that the movable end of the hinge lock 11400 is positioned at the raised distal end 11170 of the outer tube 11110. In several cases, the entire hinge lock 11400 is positioned at the enlarged distal end 11170.

[0223] Now returning to Figure 46, a surgical instrument 14000 comprises a drive shaft 14100, an end actuator 11500 and, in addition, a pivot actuator system including a pivot actuator 14310 configured to articulate the 11500 end actuator. The drive shaft 14100 comprises a hinge lock system configured to selectively lock the 14310 hinge actuator actuator and the 14500 end actuator in position. The hinge lock system comprises a hinge lock 14400 that includes the proximal and distal ends mounted on a frame 14180 of the drive shaft 14100. In at least one aspect, the hinge lock

14400 comprises a fixed beam and / or simply supported at both ends. The hinge lock 14400 further comprises an intermediate portion 14404 positioned in a cavity 14184 defined in the drive shaft structure 14180 which is configured to move laterally towards and away from a hinge actuator actuator 14310 of the hinge drive system 14300 Similar to the above, hinge lock 14400 comprises one or more spring portions 14403 configured to allow hinge lock 14400 to flex toward and away from hinge actuator 14310.

[0224] In addition to the above, the intermediate portion 14404 of the hinge lock 14400 comprises one or more teeth 14406 defined therein that are configured to engage the hinge actuator actuator 14310. The teeth 14406 are arranged in a longitudinal arrangement; however, any suitable arrangement can be used. The articulation actuator actuator 14310 comprises a longitudinal tooth array 14316 defined therein that are configured to be engaged by the articulation lock 14406 teeth. The articulation lock system additionally comprises a 14420 lock plate positioned sliding way in the drive shaft cavity 14184 which includes a longitudinal tooth array 14226 defined therein that is also configured to be engaged by the hinge lock teeth 14406. When the hinge lock 14400 is in a fully locked state, as described in more detail below, the articulation lock 14406 teeth are engaged with the 14316 actuator actuator teeth and the lock plate 14226 teeth, so that the 14400 articulation lock locks the 14310 articulation actuator actuator in position and prevents, or at least inhibits, the relative movement between the 14310 articulation actuator actuator and the shaft structure drive unit 14180.

[0225] The 14420 locking plate comprises a shoulder-shaped part 14424 that is positioned under the actuator of the 14310 pivoting actuator. The teeth of the 14426 locking plate are defined on a side edge of the 14424 shoulder-shaped part and are substantially aligned with the teeth 14316 defined in the 14310 hinge actuator actuator. In at least one case, the teeth of the 14316 hinge actuator are aligned along a first geometric axis of the teeth and the teeth of the lock plate 14406 are defined along a second tooth axis which is parallel, or at least substantially parallel, to the first tooth axis. In several cases, the actuator teeth of the 14316 actuator are defined in a plane that is parallel to a plane including the teeth of the lock plate 14406. Such arrangements allow the 14400 hinge lock to engage the lock plate simultaneously 14420 and the articulation actuator

14310. Although the first geometric axis of the teeth and the second geometric axis of the teeth are parallel to a longitudinal geometric axis of the drive axis 14100, modalities are contemplated in which the first geometric axis of the teeth and the second geometric axis of the teeth are transverse to the longitudinal axis of the drive shaft 14100.

[0226] Again with reference to Figure 46, the locking plate 14420 is slidable longitudinally inside the cavity 14184; however, the longitudinal movement of the lock plate 14420 is limited by the proximal and distal end walls 14427. As a result, the lock plate 14420 can float within the cavity of the drive shaft 14184 between the end walls 14427. In several cases , the teeth of the 14426 locking plate may not be fully aligned with the teeth of the 14316 actuator actuator when the 14400 pivot lock engages teeth 14426 and 14316. In such cases, the 14420 locking plate may move longitudinally, to a certain degree, so that the teeth on the 14426 lock plate are aligned with the teeth on the 14316 actuator actuator. In many cases, the 14420 lock plate can move in response to a locking force applied to it by the lock lock. articulation 14400. In at least one case, the locking plate 14420 may be allowed to move distally at a tooth pitch distance and proximally to a pitch distance from within its position centered, for example, where a pitch distance from within is the distance between the peaks of the adjacent lock teeth 14426 of the lock plate 14420. In other cases, the lock plate 14420 may be allowed to move distally 1/4 of a step distance from and proximally 1/4 of a tooth step distance in relation, for example, to its centralized position. In several cases, the 14420 locking plate can move proximally and distally more than a tooth pitch distance.

[0227] In addition to the above, articulation lock 14400 is configurable in three states - a self-locked state, an unlocked state and a fully locked state. When hinge lock 14400 is in a self-locking state, teeth 14406 of hinge lock 14400 are engaged with the teeth of the 14316 actuator actuator and the teeth of the drive shaft frame

14186. In such cases, hinge lock 14400 may withstand some force transmitted through the hinge actuator actuator 14310; however, the proximal and / or distal movement of the 14310 hinge actuator actuator can overcome the clamping force of the hinge lock 14400 and move the hinge lock 14400 to its unlocked configuration. In such cases, the articulation lock 14400 can flex or deflect laterally in the opposite direction to the actuator of the 11500 actuator, so that the 11500 end actuator can be articulated. Similar to the above, the spring elements 14403 of the hinge lock 14400 can resiliently return, or at least tilt, the hinge lock 14400 towards its self-locking configuration. As a result, the articulation drive system can lock and unlock itself as a result of its own movement, unless it is placed in its fully locked position, as discussed below.

[0228] Similar to the above, the drive shaft 14100 of the surgical instrument 14000 comprises a closing tube which is advanced distally during a closing stroke to close the 11500 end actuator. Before the closing stroke , the 14400 pivot lock is movable between its self-locking and unlocked configurations to allow the 11500 end actuator to be pivoted by the pivot drive system. During the closing stroke, the closing tube is configured to engage the 14400 hinge lock and place, lock and / or secure the 14400 hinge lock in its fully locked configuration. More specifically, the closure tube comprises a cam 14118 configured to engage a cam surface 14405 defined on the rear side of the articulation lock 14400 and prevent the teeth of the articulation lock 14406 from detaching from the teeth of the actuator 14316 and the teeth of the drive shaft structure

14186. Cam 14118 comprises an inclined surface 14115 which engages a correspondingly defined inclined surface on cam surface 14405, although any suitable arrangement can be used. When the closing tube is retracted proximally to allow the end actuator 11500 to be opened, flap 14118 disengages from hinge lock 14400 and hinge lock 14400 is free to move between its self-locked and unlocked positions, as discussed above, so that end actuator 11500 can be pivoted once again.

[0229] When the hinge lock 14400 moves to its configuration completely locked by the closing tube, again with reference to Figure 46, the hinge lock 14400 pushes the lock plate 14420 against a wall on the side side 14183 of the drive shaft cavity 14184. Actually, the hinge lock 14400 engages the lock plate 14420 with enough strength to secure the lock plate 14420 against the side wall 14183, so that the lock plate 14420 cannot move, or at least move substantially, longitudinally with respect to the drive shaft structure 14180. Lock plate 14420 comprises one or more projections 14422 extending from it that are configured to enter, crack and / or deflect the wall side 14183 of the drive shaft cavity 14184 when the locking plate 14420 is pushed against the side wall 14183 to prevent, or at least reduce the possibility of the locking plate 14420 if moving see longitudinally in relation to the drive shaft structure

14180.

[0230] In addition to the above, the drive shaft structure 14180 comprises one or more cavities, or openings, defined therein that are configured to allow and / or facilitate deflection of the sidewall 14183. For example, as illustrated in Figure 46, the drive shaft structure 14180 comprises cavities 14182 defined therein that are aligned, or at least substantially aligned, with the projections 14422. When the locking plate 14420 is disposed laterally by the closing tube, as discussed above, the wall lateral 14183 moves elastically into the cavities 14182 and the locking plate 14420 is locked in position. In such cases, the engagement between the drive shaft structure 14180 and the locking plate 14420 prevents the actuator of the 14310 hinge actuator from moving longitudinally and locks the end actuator 11500 in position. When the closing tube is retracted and disengaged from the Articulation Lock 14400, the side wall 14183 can return to its non-flexed state and move the lock plate 14420 laterally. At such a point, locking plate 14420 is unlocked and end actuator 11500 can be pivoted, as described above.

[0231] A 15000 surgical instrument is illustrated in Figures 47 to 49 and is similar to the 14000 surgical instrument in many respects, most of which will not be repeated here, for the sake of brevity. Among other things, the surgical instrument 15000 comprises a drive shaft, an end actuator 11500 and a hinge actuator system including a hinge actuator actuator 14310. The surgical instrument 15000 further comprises a hinge lock system that includes a joint lock 15400 which is, similar to the above, movable between a self-locking position, an unlocked position and a completely locked position. The hinge lock system further comprises a lock plate 15420 which is similar to the lock plate 14420 in many respects. For example, lock plate 15420 is movable laterally in engagement with wall 14183. In addition, for example, lock plate 15420 is movable longitudinally to float in a suitable locked position in which a tooth array 15426 defined on the plate locking device 15420 engages with the teeth 14406 of the joint locking 15400, as shown in Figure 48. That said, the drive shaft of the surgical instrument 15000 additionally comprises a distal spring 15429 positioned between the locking plate 15420 and a distal end wall 15427 defined in the drive shaft structure and, in addition, a proximal spring

15429 positioned between lock plate 15420 and a proximal end wall 15427 defined in the drive shaft structure. The springs 15429 are configured to position the lock plate 15420 in a centralized or balanced position between the end walls 15427, which is illustrated in Figure 47. Such a centralized position creates a proximal gap (PG) and a distal gap (DG) between the end walls 15427 and the lock plate 15420 which are the same, or at least substantially the same, with each other. That said, springs 15429 can experience different deflections or loads when lock plate 15420 rests in engagement with hinge lock 15400, as shown in Figure 49, which can create uneven spans PG and DG.

[0232] A surgical instrument 16000 is illustrated in Figures 50 to 52 and is similar to surgical instruments 14000 and 15000 in many respects, most of which will not be repeated here, for the sake of brevity. Among other things, the 16000 surgical instrument comprises a drive shaft, an 11500 end actuator and a hinge driver system including a 16310 hinge driver. Referring primarily to Figure 50, the 16000 surgical instrument further comprises a locking system articulation that includes a 16400 articulation lock that is, similar to the above, configurable in a self-locking configuration, an unlocked configuration and a completely locked configuration. The hinge lock system additionally comprises a lock plate 16420 which is similar to the lock plate 14420 in many respects. For example, lock plate 16420 is movable laterally in engagement with wall 14183, as shown in Figure

51. In addition, for example, the lock plate 16420 is movable longitudinally to float in a suitable locked position in which the teeth 16426 of the lock plate 16420 are engaged with the teeth

Pivot lock 16406, as shown in Figure 52. In addition, pivot latch 16406 teeth 16400, latch plate 16426 teeth 16420 and pivot trigger 16316 lock teeth 16310 are configured and arranged to provide a plurality of positions, or permutations of positions, in which hinge lock 16400 can lock hinge driver 16310 to lock plate 16420. For example, the hinge lock system has achieved a completely locked configuration in a set of illustrated positions in Figure 51 and to a completely locked configuration in a different set of positions illustrated in Figure 52.

[0233] The adaptability discussed above of the joint locking system can be obtained through tooth steps of the joint locking teeth 16406, the teeth of the 16316 articulation driver and the teeth of the locking plate 16426. For example, with reference mainly to Figure 50, the articulation lock teeth 16406 are defined in a first step 16407, the articulation trigger teeth 16316 are defined in a second step 16317, and the teeth of the lock plate 16426 are defined in a third step 16427 The first step is different from the second step and the third step - the second step is different from the first step and the third step - and the third step is different from the first step and the second step, although modalities are foreseen in which two of the first step, second step and third interval are the same. Again with reference to Figure 50, the third step 16427 of the teeth of the lock plate 16426 is greater than the second step 16317 of the teeth of the 16316 pivoting driver, and the second step 16317 is greater than the first step 16407 of the teeth of the locking latch. articulation 16406, although any suitable arrangement can be used.

[0234] A 17000 surgical instrument is illustrated in Figures 53 to

56 and is similar to the surgical instrument 11000 in many respects, most of which will not be repeated here, for the sake of brevity.

The surgical instrument 17000 comprises a drive shaft, an end actuator 11500 pivotally connected to the drive shaft around an articulation joint 11200 and a joint actuator system configured to articulate the end actuator around the pivot joint 11200. Similar to the above, the pivot drive system comprises a pivot connection 17320 mounted pivotally to the claw 11600 around a pin 11620 and a pivot drive 17310 mounted pivotally to the pivot connection 17320 around a pin 17315. The surgical instrument 17000 further comprises a hinge lock 17400 movably mounted to a drive shaft structure of the surgical instrument 17000 which is movable between an unlocked position and a locked position.

The hinge lock 17400 comprises a distal end 17402 fixedly mounted to the drive shaft structure and a proximal end 17404 mounted slidably to the drive shaft structure.

More specifically, the drive shaft structure comprises a pin that extends into an opening defined at the distal end 17402 of the hinge lock 17400 and a guide projection 17114 that extends into an elongated opening defined at the proximal end 17404. cases, the drive shaft structure may comprise two or more pins that extend into the openings defined at the distal end 17402 of the hinge lock 17400 to secure the distal end 17402 to the drive shaft structure and prevent the distal end 17402 rotate in relation to the drive shaft structure.

As a result of the above, at least the proximal end 17404 of the hinge lock 17400 is movable with respect to the drive shaft structure to engage the hinge actuator 17310 and lock the hinge system and end actuator 11500 in position.

[0235] In addition to the above, the articulation actuator 17310 comprises a longitudinal tooth rack 17316 defined therein and the articulation lock 17400 comprises a longitudinal tooth rack 17406 defined therein. When the hinge lock 17400 is in its unlocked position, as shown in Figures 53 and 54, the teeth 17406 of the hinge lock 17400 are not engaged with the teeth 17316 of the hinge trigger 17310. In such cases, the hinge trigger 17310 may move freely in relation to the hinge lock 17400 to pivot the end actuator 11500. When the hinge lock 17400 is in a partially locked position, as shown in Figure 55, the teeth of the hinge lock 17406 are partially engaged with the teeth of the articulation trigger 17316. In these cases, the proximal and distal movement of the articulation trigger 17310 is prevented by the articulation lock 17400; however, the articulation trigger 17310 can still move freely in relation to the articulation lock 17400 to articulate the end actuator 11500. When the articulation lock 17400 is in a fully locked position, as shown in Figure 56, the pivot lock teeth 17406 are fully engaged with pivot trigger teeth 17316. In such cases, the proximal and distal movement of pivot trigger 17310 and pivot of end actuator 11500 are prevented by pivot lock 17400.

[0236] In addition to the above, surgical instrument 17000 does not include a biasing member configured to move hinge lock 17400 towards hinge trigger 17310 other than a closing member, or tube, 17110. Closing tube 17110 is configured to engage the hinge lock

17400 and move the 17400 hinge lock from its unlocked position (Figure 54) to its partially locked (Figure 55) and completely locked (Figure 56) positions. Similar to the above, the closing tube 17110 comprises a cam 17118 configured to engage a defined cam surface over the hinge lock 17400, although other arrangements may be used. Closing tube 17110 is configured to move hinge lock 17400 between its unlocked position and its partially locked position when closing tube 17110 is moved distally through a partial closing stroke (PCs) that at least partially closes the actuator. end 11500. In such cases, the end actuator 11500 of the surgical instrument 17000 can be used to hold a patient's tissue, for example. Closing tube 17110 is configured to move hinge lock 17400 to its fully locked position when closing tube 17110 is moved distally through a full closing stroke (FCS) that completely closes the end actuator

11500. In such cases, the 11500 end actuator of the 17000 surgical instrument can be used to hold a patient's tissue, for example.

[0237] As discussed above, the locking force applied to the 17310 pivot drive by the 17400 pivot lock increases as the 17110 closing tube advances distally. In other words, the hinge lock force is a function of the stroke of the 17110 closing tube. In addition to the above, with reference now to Figure 57, the lock force between the 17310 hinge driver and the 17400 hinge lock is represented by line 17101. As shown in Figure 57, the teeth of the 17406 hinge lock initially become engaged with the teeth of the 17316 hinge driver during the partial closing stroke.

In at least one case, such initial engagement of teeth 17406 and 17316 occurs after approximately 0.050 "of the closing stroke of closing tube 17110, although any suitable distance can be used. Notably, such initial engagement of teeth 17406 and 17316 does not necessarily coincide with the end of the partial closing stroke; instead, it can occur at some point during the partial closing stroke (PCS) .This also occurs at some point during the full closing stroke (FCS). does not comprise a coupling lock force, instead a coupling lock force between teeth 17406 and 17316 is only established at some point during the total closing stroke (FCS). closing stroke (FCS) has a length of approximately 0.260 ", for example.

[0238] An 18000 surgical instrument is illustrated in Figures 58 to 60 and is similar to surgical instruments 11000 and 17000 in many respects, most of which will not be repeated here, for the sake of brevity. The surgical instrument 18000 comprises a drive shaft, a 11500 end actuator pivotally connected to the drive shaft around a pivot joint and a pivot system configured to pivot the 11500 end actuator. The drive shaft comprises a structure 18180 including the first and second longitudinal racks of teeth 18186 that are parallel, or at least substantially parallel to each other, although the racks 18186 may extend transversely with respect to each other. The surgical instrument 18000 additionally comprises a hinge lock 18400 and a closing member including a cam 18118. The hinge lock 18400 includes a first lock arm 18410 configured to engage the first longitudinal tooth rack.

18186 and a second locking arm 18420 configured to engage the second longitudinal tooth rack 18186. Referring mainly to figures 59 and 60, the first locking arm 18410 comprises a first cam surface 18415 defined therein and the second locking arm 18420 comprises a second cam surface 18425 defined therein that is configured to be brought into contact by cam 18118 during a closing stroke of the closing member and displaced or flexed out in a fully locked engagement with the 18186 longitudinal tooth racks. In addition, one or both locking arms 18410 and 18420 also engage the pivot system to lock the end actuator 11500 in place when locking arms 18410 and 18420 are moved outwardly in engagement with the drive shaft structure 18180 .

[0239] Once displaced or flexed in their fully locked states, locking arms 18410 and 18420 define a longitudinal slot 18430 between them, which is configured to allow cam 18118 to pass through it during the rest of the closing stroke, for example. In addition, in such cases, the cam 18118 forces the articulation lock 18400 in engagement with the frame 18180 and securely fixes the lock arms 18410 and 18420 in their completely locked positions.

[0240] In at least one alternative modality, in addition to the above, the first locking arm 18410 of the articulation lock 18400 can be configured to engage the 18180 drive shaft structure of the 18000 surgical instrument, while the second locking arm 18420 of the 18400 hinge lock can be configured to engage the 18000 surgical instrument hinge system.

[0241] A 19000 surgical instrument is illustrated in Figures 61 to 65 and is similar to the 11000 surgical instrument in many respects, most of which will not be repeated here, for the sake of brevity. The surgical instrument 19000 comprises a drive shaft 19100 including a closing member 19110, an end actuator 11500 pivotally connected to the drive shaft 19100 around a joint 11200 and a drive system 19300 including a pivot actuator 19310 configured to pivot end actuator 11500 around pivot joint 11200. Referring mainly to Figure 61, surgical instrument 19000 additionally comprises a pivot lock 19400 configured to selectively lock the pivot actuator system 19300 and lock the end actuator 11500 in position. The drive shaft 19100 additionally comprises a frame 19180 and the articulation lock 19400 is movably mounted to the frame 19180 between an unlocked position (Figure 61), a partially locked position (Figure 63) and a locked position (Figure 64). As described in greater detail below, the articulation lock 19400 is movable laterally towards the articulation actuator 19310 to bring the articulation lock 19400 in close proximity to the articulation actuator 19310 (Figure 63) and also transversely in interference with articulation actuator 19310 (Figure 64).

[0242] In addition to the above, the drive shaft structure 19180 comprises a proximal guide protrusion 19182 and a distal guide protrusion 19184. The proximal guide protrusion 19182 extends into an elongated lateral slot defined at a proximal end 19402 of the lock articulation 19400 and, similarly, the distal guide protrusion 19184 extends into a lateral elongated slot defined at a distal end 19404 of the articulation lock 19400. The lateral elongated slots allow the 19400 articulation lock to move laterally in direction and in the opposite direction to the 19310 articulation actuator, as described above. The lateral elongated slits also define the lateral path of the 19400 articulation lock and prevent, or at least substantially avoid, the longitudinal movement of the 19400 articulation lock in relation to the 19180 drive shaft structure. articulation lock 19400 can guide the articulation lock 19400 between an unlocked position (Figure 61) in which the 19406 lock teeth of the articulation lock 19400 are not engaged with a longitudinal tooth rack 19316 defined in the articulation drive 19310, a position partially locked (Figure 63) in which the 19406 locking teeth are partially engaged with teeth 19316, and a completely locked position (Figure 64) in which the 19406 locking teeth are completely engaged with teeth 19316.

[0243] In addition to the above, the hinge lock 19400 additionally comprises a longitudinal cam slot 19408 defined therein and the closing member 19110 comprises a cam pin 19188 positioned in the cam slot 19408. When the closing member 19110 is in a non-actuated or open position (Figure 61), cam pin 19188 is positioned in a proximal portion 19408a of cam slot 19408. When closing member 19110 is moved distally to a partially actuated, or partially closed, as shown in Figure 62, cam pin 19188 moves to a central portion 19408b of cam slot 19408. In such cases, cam pin 19188 moves pivot lock 19400 toward pivot driver 19310. In In such cases, however, the 19406 teeth of the articulation lock 19400 may not be engaged with the teeth 19316 of the articulation driver 19310, and as a result, the articulation driver 19310 may still move to pivot end actuator 11500 in relation to drive shaft 19100. As a result, end actuator 11500 can be pivoted when the closing stroke of closing member 19110 has only been partially completed.

[0244] When closing member 19110 is moved further distally, as shown in Figure 63, cam pin 19188 moves to a distal portion 19408c of the cam slot

19408. In such cases, the cam pin 19188 moves the articulation lock 19400 in close proximity to the articulation actuator 19310 and in partial interlacing with the teeth 19316 of the articulation actuator 19310. That said, such partial interleaving between teeth 19406 and 19316 can only resist a certain amount of force transmitted through the articulation actuator 19310 and such resistance can be overcome to move the articulation actuator 19310 in relation to the articulation lock 19400 and articulate the actuator 11500.

[0245] In addition to the above, the articulation lock 19400 is not raised or lowered transversely in relation to the structure of the drive shaft 19180 during the partial closing stroke of the closing member 19110 (Figures 61 to 63). Instead, hinge lock 19400 is lifted upwards so that the teeth 19406 of hinge lock 19400 fully engage teeth 19316 of hinge driver 19310 and lock hinge driver 19310 in position during the final or last portion of the closing stroke of the closing member 19110, as shown in Figure 64. The hinge lock 19400 moves upwards by means of a different cam pin that extends from the closing member 19110, that is, the locking pin cam 19189 that engages hinge lock 19400 at the end of the closing stroke of closing member 19110. Notably, cam pin 19189 is not engaged with hinge lock 19400 at the beginning of the closing stroke or during the partial closing stroke of the closing member 19110. At most, the cam pin 19189 can slide the bottom of the articulation lock 19400 during the partial closing stroke. That said, with reference mainly to Figure 65, the hinge lock 19400 comprises a cutout, or recess, 19409 defined therein that provides a gap between the cam pin 19189 and the hinge lock 19400 during the partial closing stroke. That said, cam pin 19189 comes into contact with articulation lock 19400 when cam pin 19189 reaches the end of recess 19409 and, in such cases, activates articulation lock 19400 transversely upwards so that the teeth of lock 19406 interference interlock with teeth 19316 of the articulation driver 19310 and the articulation lock 19400 is placed in its completely locked position, as shown in Figure 64. At such a point, the articulation driver 19310 is locked in position and not can be moved longitudinally to articulate end actuator 11500.

[0246] Again with reference to Figure 65, the teeth 19316 of the articulation driver 19310 are angled, or inclined, in relation to the longitudinal geometric axis of the drive shaft 19100. The 19406 lock teeth of the 19400 articulation lock are not angled, or are angled in a different orientation with respect to teeth 19316. As a result, lock teeth 19406 of pivot lock 19400 can be partially engaged with teeth 19316 of pivot driver 19310 when pivot lock 19400 is in its lowered position ( Figure 63) and completely engaged with teeth 19316 when the articulation lock 19400 is in its raised position (Figure 64).

[0247] In order to unlock the articulation system 19300 from the surgical instrument 19000, the closing member 19110 needs to be retracted to disengage the cam pin 19189 from the articulation lock 19400 so that the articulation lock 19400 can return to its lowered position. Once the cam pin 19189 has been disengaged from the articulation lock 19400, the proximal retraction of the cam pin 19188 can drive the articulation lock 19400 down as the cam pin 19188 is pulled proximally through the cam slot 19408. In addition, cam pin 19188 can move hinge lock 19400 away from hinge driver 19310 when it is pulled proximally. In various embodiments, the drive shaft 19110 can comprise one or more bias members, such as springs, for example, configured to bend or push the hinge lock 19400 down to quickly reset the hinge lock to an unlocked position.

[0248] A 20000 surgical instrument is illustrated in Figures 66 to 68 and is similar to surgical instruments 11000, 17000, 18000 and 19000 in many respects, most of which will not be repeated here, for the sake of brevity. The surgical instrument 20000 comprises a drive shaft that includes a 20110 closing tube, an end actuator 11500 pivotally mounted to the drive shaft around a hinge joint 11200 and a hinge system configured to pivot the end actuator 11500 in relation to the drive shaft. Similar to the above, the pivot system comprises a pivot connection 20320 pivotally attached to the end actuator 11500 and, in addition, a pivot actuator 20310 pivotally attached to the pivot connection

20320. In use, the articulation actuator 20310 moves proximally and / or distally to actuate the articulation connection 20320 and to articulate the end actuator 11500. The surgical instrument 20000 additionally comprises a joint lock system comprising a locking gear pivot 20400 pivotally mounted to a drive shaft structure around a fixed geometry axis. The articulation lock gear 20400 comprises an annular tooth array 20406 that is engaged in engagement with a longitudinal array of teeth 20316 defined in the articulation actuator 20310. As a result, with reference generally to Figure 66, the articulation lock gear 20400 will rotate in response to the proximal and / or distal movement of the 20310 hinge actuator until the hinge lock 20400 gear is locked in position by the closing tube 20110, as shown in Figure 68.

[0249] In addition to the above, the articulation lock system additionally comprises locking arms 20405 extending from the drive shaft structure to a central opening defined in the articulation lock gear 20400 and, when the closing tube 20110 is moved distally during a closing stroke to close the end actuator 11500, a cam, or wedge 20118 of the closing tube 20110 is configured to engage the lock arms 20405 and extend the lock arms 20405 outwardly in engagement with the articulation lock gear 20400. Since the lock arms 20405 are engaged with the articulation lock gear 20400, the lock arms 20405 can prevent the rotation of the articulation lock 20400 and also the longitudinal movement of the articulation actuator 20310. In such cases, the locking arms 20405 can prevent, or at least substantially prevent, the articulation of the 11500 end actuator until the wedge 20118 of the closing tube 20110 is retracted proximally during an opening stroke and the locking arms 20405 return resiliently to their non-flexed or unlocked configurations.

[0250] In addition to the above, the articulation system of the surgical instrument 20000 can be placed in an unlocked configuration (Figure 66), a partially locked configuration (Figure 67) and a completely locked configuration (Figure 68). The articulation system can be placed in its partially locked configuration (Figure 67) when the 20110 closing tube is advanced distally through a partial closing stroke (PCS). In such cases, the end actuator 11500 is at least partially closed but can still be pivoted, although the locking arms 20405 can be partially engaged with the pivoting lock gear 20400. More particularly, the pivoting lock gear 20400 it can still rotate despite the displacement created by the partial engagement of the 20405 lock arms against the 20400 articulation lock gear. In at least one case, the PCS is approximately 0.050 ", for example. The articulation system can be placed in its completely locked configuration (Figure 68) when the closing tube 20110 is advanced distally through a full closing stroke (PCS). In such cases, the end actuator 11500 is completely closed and cannot be pivoted until the articulation returns to its partially locked and / or unlocked configurations.

[0251] A 21000 surgical instrument is illustrated in Figures 69 to 71 and is similar to surgical instruments 11000, 17000, 18000, 19000 and 20000 in many respects, most of which will not be repeated here, for the sake of brevity. The surgical instrument 21000 comprises a drive shaft that includes a closing member 21110, an end actuator 11500 pivotally mounted to the drive shaft around a pivot joint 11200 and a pivot system that includes an actuator. articulation

21130 configured to articulate end actuator 11500 in relation to the drive shaft. The surgical instrument 21000 further comprises an articulation lock system comprising a 21400 articulation lock gear pivotally mounted to a drive shaft structure around a fixed geometric axis. The hinge lock gear 21400 comprises an annular tooth array 21406 that is engaged in engagement with a longitudinal hinge matrix 21316 defined on the hinge actuator 21310. As a result, with reference generally to Figure 69, the hinge lock gear 21400 rotates in response to the proximal and / or distal longitudinal movement of the articulation actuator 21310 until, as described in more detail below, the articulation lock 21400 gear is locked in position by the closing member 21110 (Figure 71).

[0252] In addition to the above, the articulation locking system of the surgical instrument 21000 additionally comprises a mobile locking element 21405 that is mounted in a sliding way to the drive shaft structure. More specifically, with reference mainly to Figure 69, the locking element 21405 comprises a guide projection 21402 extending from it and extending into a lateral elongated slot 21403 defined in the drive shaft structure that is configured to allow the locking element 21405 slide laterally towards and / or in the opposite direction to articulation actuator 21310. In addition, with reference mainly to Figure 70, locking element 21405 slides laterally within a defined opening in the locking gear articulation 21400 between an unlocked position (Figure 69) and a locked position (Figure 71). The locking element 21405 comprises an annular matrix of the locking teeth 21407 and the hinge locking gear 21400 comprises an annular matrix of the locking teeth 21408 defined around its internal opening and, when the locking element 21405 is in in its unlocked position (Figure 69), the locking teeth 21407 of the locking element 21405 are not engaged with the locking teeth 21408 of the hinge locking gear 21400. When the locking element 21405 is in its locked position (Figure 71) , the locking teeth 21407 of the locking element 21405 are engaged with the locking teeth 21408 of the pivoting locking gear 21400 so that the pivoting locking gear 21400 cannot rotate and, as a result, the pivoting actuator 21300 is prevented to move longitudinally to articulate the 11500 end actuator.

[0253] Figures 69 to 71 illustrate the distal progression of closing member 21110 during a closing course. Figure 69 illustrates the closing member 21110 in a non-actuated or open position. In such a position, the closing member 21110 is not engaged with the locking element 21405. Figure 70 illustrates the closing member 21110 in a partially closed position where the closing member 21110 has the end actuator 11500 at least partially closed . In such a position, a cam surface 21115 of the closing member 21110 engaged the locking member

21405. In at least one case, closing member 21110 moves distally approximately 0.050 "from its open position (Figure 69) to its partially closed position (Figure 70). Figure 71 illustrates closing member 21110 in a completely closed position where the closing member 21110 has the end actuator 11500 completely closed In such a position, the cam surface 21115 moved by the locking element 21405 and the locking element 21405 was displaced by the total thickness of the closing member 21110.

[0254] In view of the above, a surgical instrument may include a joint locking system configured to prevent the surgical instrument's end actuator from being articulated and / or unintentionally driven back by a load, or torque, applied to the end actuator. At least a portion of the articulation lock system can move in engagement with a surgical instrument pivot drive system to prevent pivoting of the end actuator. In at least one case, a hinge lock can be an integral part of the hinge drive system, as described in more detail below.

[0255] Referring to Figures 72 to 74, a 22000 surgical instrument comprises a drive shaft and a 22300 pivot drive system that is configured to pivot an end actuator, such as a 11500 end actuator, for example, the surgical instrument 22000 in relation to the drive shaft. The hinge drive system 22300 comprises a hinge drive 22310 and a pinion gear 22320. The hinge drive 22310 comprises a longitudinal tooth rack 22316 defined therein that is operationally engaged with teeth 22326 of pinion gear 22320. When the articulation actuator 22310 is moved distally, the pinion gear 22320 rotates in a first direction. Correspondingly, pinion gear 22320 rotates in a second direction when hinge actuator 22310 is moved proximally. The pinion gear 22320 comprises an inclined gear 22330 mounted fixedly thereto, so that the inclined gear 22330 rotates with the pinion gear 22320 about a common geometric axis of rotation. The combined set of pinion gear 22320 and inclined gear 22330 is pivotally mounted on the drive shaft of the surgical instrument 22000.

[0256] In addition to the above, teeth 22336 of inclined gear 22330 are in engagement with teeth 22346 of an inclined gear 22340 which is pivotally mounted around a threaded pivoting pivot screw 22350. More specifically, the inclined gear 22340 comprises a portion of nut that includes an opening at least partially threaded that is threadably engaged with the hinge drive screw 22350. When the inclined gear 22340 is rotated in a first direction by the hinge gear 22310 through the inclined gear 22330, inclined gear 22340 rotates pivot screw 22350 in a first direction. Likewise, the inclined gear 22340 rotates the pivot screw 22350 in a second direction when the inclined gear 22340 is rotated in a second direction. In addition, the 11500 end actuator is rotated in a first direction when the articulation actuator screw 22350 is rotated in its first direction and, correspondingly, in a second direction when the drive shaft of the threaded articulation actuator 22350 is rotated in its second direction.

[0257] In addition to the above, the pitch of the threads on the 22350 threaded pivot screw can be selected to prevent indentation within the pivot drive system

22300. In other words, a steep pitch of the threads defined in the articulation drive screw 22350 would be able to resist a force and / or torque transmitted proximally from the end actuator 11500 through the articulation drive system 22300 and, as a result , you can prevent the 11500 end actuator from being unintentionally pivoted. As such, the thread pitch can serve as an integral pivot lock with the 22300 pivot drive system. In at least one case, the pivot drive screw comprises an ACME drive screw, for example.

[0258] Referring to Figures 75 to 79, a 23000 surgical instrument comprises a drive shaft and a 23300 pivot drive system that is configured to pivot an end actuator, such as a 11500 end actuator, for example, the surgical instrument 23000 in relation to the drive shaft. The articulation actuator system 23300 comprises an articulation actuator 23310 and a pinion gear 23320. The articulation actuator 23310 comprises a longitudinal rack of teeth 23316 defined therein that is operationally engaged with teeth 23326 of pinion gear 23320. When the articulation actuator 23310 is moved distally, the pinion gear 23320 rotates in a first direction. Correspondingly, the pinion gear 23320 rotates in a second direction when the hinge driver 23310 is moved proximally. The pinion gear 23320 comprises a worm gear 23330 mounted fixedly to it, so that the worm gear 23330 rotates with the pinion gear 23320 about a common geometric axis of rotation . The combined set of pinion gear 23320 and worm gear 23330 is pivotally mounted on the drive shaft of the surgical instrument 23000.

[0259] In addition to the above, the teeth 23336 of the worm gear 23330 are in engagement with the teeth 23346 of a worm thread 23340 which is pivotally mounted to the drive shaft structure. The worm thread 23340 comprises a pinion gear 23350 mounted fixedly to it so that the pinion gear 23350 rotates with the worm thread 23340 around a common axis of rotation. Pinion gear 23350 is operationally coupled to a translatable hinged output driver 23360. More specifically, pinion gear 23350 comprises teeth 23356 that are in engagement with a tooth rack 23366 defined on output driver 23360. When the worm 23340 is rotated in a first direction by the articulation driver 23310 through the worm gear 23330, the pinion gear 23350 drives the output driver 23360 distally. Correspondingly, worm 23340 and pinion gear 23350 drive output driver 23360 proximally when worm 23340 is rotated in a second direction by the worm gear 23330. In addition, the end actuator 11500 is rotated in a first direction when the output driver 23350 is driven distally by the hinge drive system 23330 and in a second direction when the output driver 23350 is driven proximally by the hinge drive system 23330.

[0260] In addition to the above, the pitch of the threads on the worm thread 23340 can be selected to avoid indentation within the 23300 hinge drive system. In other words, a steep pitch of the threads defined on the worm thread 23340 , for example, would be able to withstand a force and / or torque transmitted proximally from the end actuator 11500 through the hinge actuator system 23300 and can prevent the end actuator 11500 from being unintentionally articulated. As such, the thread pitch can serve as an integral hinge lock with the 23300 hinge drive system.

[0261] A surgical instrument 12000, illustrated in Figures 32 to 34B, is similar to the surgical instrument 11000 in several aspects, most of which will not be repeated here, for the sake of brevity. In addition to a drive shaft 11100, an end actuator 11500 and a hinge joint 11200, the surgical instrument 12000 additionally comprises a clamp firing system 12900, for example, including a firing bar 12910 that extends through the joint hinge 11200. In use, the firing bar 12910 is translatable distally to perform a staple firing stroke and retracts proximally after at least a portion of the staple firing course has been completed. The firing bar 12910 extends through a channel, or slot, 11190 defined in the structure 11180 of the driving shaft 11100 which is configured to receive and / or guide firing bar 12910 closely as firing bar 12910 moves in relation to to the drive shaft 11100. Similarly, end actuator 11500 comprises a channel, or slot 11590, defined in structure 11580 of end actuator 11500 which is also configured to receive narrowly and / or guide firing bar 12910 according to firing rod 12910 moves relative to end actuator 11500.

[0262] In addition to the above, channels 11190 and 11590 do not extend into the hinge joint 11200 and, without further ado, the 12910 firing bar may not be supported within the hinge joint 11200. When the end actuator 11500 is in a non-hinged configuration (Figure 34), the 12910 firing bar is unlikely to warp within the 11120 hinge joint during the staple firing stroke - however, the probability of the 12910 firing bar warping laterally during the stroke clamp trigger increases when the 11500 end actuator is in an articulated configuration (Figures 34A and 34B). To reduce the possibility of such deformation, the surgical instrument 12000 additionally comprises a firing rod support 12400 configured to support firing rod 12910. The firing rod support 12400 comprises a proximal portion 12410 connected to the structure of the firing shaft. drive 11180, a distal portion 12430 connected to the frame of the end actuator 11580 and an intermediate portion 12420 extending between the proximal portion 12410 and the distal portion

12430. Portions 12410, 12420 and 12430 of the 12400 firing bar holder are integrally formed; however, other modalities are provided for in which the portions 12410, 12420 and 12430 are assembled together and / or comprise separate components.

[0263] In addition to the above, the distal portion 12430 of the firing bar 12400 is fixedly mounted to the support of the end actuator 11580 and does not move, or at least substantially moves, in relation to the structure of the actuator. end 11580. The intermediate portion 12420 of the firing bar holder 12400 comprises one or more portions having a reduced cross section which, among other things, allows the firing bar holder 12400 to flex within the hinge joint 11200 when the end actuator 11500 is articulated. The proximal portion 12410 of the firing bar holder 12400 is slidably mounted on the drive shaft structure 11180 so that the firing bar support 12400 can translate in relation to the structure of the driving shaft 11180 when the end actuator 11500 is articulated. That said, the proximal portion 12410 of the firing bar support 12400 comprises a proximal head 12415 that is slidable within a chamber, or cavity, 11185 defined within the drive shaft structure 11180 that can limit the displacement of the support of the 12400 firing bar. However, the modalities are provided without such a travel restriction. In any case, the proximal portion 12410, the intermediate portion 12420 and the distal portion 12430 of the firing bar support 12400 cooperatively define a channel, or slot, 12490 that is configured to support firing bar 12910 - especially within the articulated joint 11200

- and reduce the possibility of the 12910 firing bar warping during the clamp firing stroke, for example.

[0264] In several cases, the firing rod 12910 is comprised of a plurality of parallel layers, or at least substantially parallel. The layers are affixed to a distal cutting member and can partially translate or slide longitudinally in relation to each other - especially within the hinge joint

11200. Each of these layers is configured to transmit a load in the same direction, that is, proximally or distally, even though these layers can move, or slide, in relation to each other. In addition to the above, such layers can widen laterally relative to each other - especially within the articulation joint 11200 - when the end actuator 11500 has been articulated. The intermediate portion 12420 of the firing bar holder 12400 comprises a plurality of connected control elements which can at least reduce, if not prevent, the relative lateral widening of the firing bar layers. Alternatively, as mentioned above, one or more of the control elements can be disconnected from each other.

[0265] In addition to or instead of the 12400 firing bar holder, the surgical instrument 12000 comprises one or more dividers that separate and control the firing bar layers 12910. Referring to Figures 34 to 34B, the 11110 drive shaft it comprises a divider 12920 positioned within the layers of the 12910 firing bar. Two layers of the 12910 firing bar are positioned on one side of the 12920 divider, while two layers are positioned on the other side of the 12920 divider, although any suitable provision can be used. The divider 12920 prevents half the layers of the firing bar 12910 from extending outward when the end actuator 11500 is pivoted. In other words, divider 12920 prevents the two rightmost layers of the firing bar from extending to the left when end actuator 11500 is hinged to the right (Figure 34A) and, similarly, divider 12920 prevents that the two leftmost layers of the firing bar widen to the right when the end actuator 11500 is pivoted to the left (Figure 34B). The divider 12920 extends through the hinge joint 11200 and the firing bar support 12400 and into the end actuator 11500, and can flex when the end actuator 11500 is pivoted. Consequently, in such cases, divider 12920 is flexible. The divider 12920 is mounted on the 11180 frame of the 11110 drive shaft and does not move relative to the 11180 frame; however, modalities are provided for in which the divider 12920 is not mounted to the structure 11180 and can float within the layers of the firing bar.

[0266] A surgical instrument 13000, illustrated in Figures 35 to 39B, is similar to surgical instruments 11000 and 12000 in several respects, most of which will not be repeated here, for the sake of brevity. In addition to a drive shaft 13100, an end actuator 13500 and a hinge joint 11200, the surgical instrument 13000 additionally comprises a clamp firing system 12900, for example, including a firing bar 12910 that extends through the gasket hinge 11200. In use, the firing bar 12910 is translatable distally to perform a staple firing stroke and retracts proximally after at least a portion of the staple firing course has been completed. With reference mainly to Figures 39 to 39B, the firing bar 12910 extends through a channel, or slot, 13190 defined in the structure 13180 of the driving shaft 13100 which is configured to receive closely and / or guide the bar firing rod 12910 as firing rod 12910 moves relative to the driving shaft 11100. Similarly, end actuator 13500 comprises a channel, or slot, defined in structure 13580 of end actuator 13500 which is also configured to receive closely and / or guide firing bar 12910 as firing bar 12910 moves relative to end actuator 13500.

[0267] When end actuator 13500 is in a non-hinged configuration (Figure 39), in addition to the above, firing bar 12910 is unlikely to warp into joint 11120 during the clamp firing stroke - no However, the probability that the 12910 firing bar will bend laterally during the staple firing stroke increases when the 13500 end actuator is in an articulated configuration (Figures 39A and 39B). To reduce the possibility of such deformation, surgical instrument 13000 further comprises a firing bar holder 13400 configured to support firing bar 12190. The firing bar holder 13400 comprises a first side plate 13410 and a second side plate 13420. The side plates 13410 and 13420 are positioned on opposite sides of the firing bar 12910. Each side plate 13410, 13420 comprises a proximal portion connected to the structure of the drive shaft 13180, a distal portion connected to the structure of the end actuator 13580 and a portion intermediary extending between the proximal portion and the distal portion. The portions of each plate 13410, 13420 are integrally formed; however, other modalities are envisaged in which the portions are assembled together and / or comprise separate components.

[0268] In addition to the above, the first side plate 13410 comprises a distal portion 13416 that is fixedly mounted to the end actuator support 13580 and does not move, or at least substantially move, relative to the structure of the actuator. end 13580. Similarly, the second side plate

13420 comprises a distal portion 13426 which is fixedly mounted to the structure of the end actuator 13580 and does not move, or at least move substantially, with respect to the structure of the end actuator 13580. The first side plate 13410 comprises a proximal portion 13412 which it is slidably mounted on the drive shaft structure 13180, so that the first side plate 13410 can translate in relation to the drive shaft structure 13180 when the end actuator 13500 is pivoted. The proximal portion 13412 comprises a head that is slidable within a chamber, or cavity, 13185 defined within the structure of the drive shaft 13180 that can limit the displacement of the firing bar support 13400. Similarly, the second side plate 13420 comprises a proximal portion 13422 which is slidably mounted on the drive shaft structure 13180 so that the firing rod holder 13400 can shift over the drive shaft structure 13180 when the end actuator 13500 is articulated. The proximal portion 13422 comprises a head which is slidable within the chamber 13185 defined within the structure of the drive shaft 13180 which can also limit the displacement of the firing bar holder 13400.

[0269] The first side plate 13410 comprises a flexible portion 13414 positioned on the hinge joint 11200 that allows the distal portion 13416 of the first side plate 13410 to flex with respect to the proximal portion 13412 and accommodate the end actuator joint 13500. A flexible portion 13414 extends laterally from the first side plate 13410 and comprises a hinge including the spans 13413 defined therein, which allow rotation within the first side plate 13410. In addition to or instead of the above, the first side plate 13410 comprises longitudinal openings 13415 defined therein that allow the first side plate 13410 to flex within the end actuator 13500 and accommodate the hinge of the end actuator 13500. The first side plate 13410 can comprise any number and configuration of openings and / or recesses defined there in any suitable location that is configured to allow the ap first side plate 13410 flexes during articulation of the end actuator

13500. Similarly, the second side plate 13412 comprises a flexible portion 13424 positioned on the hinge joint 11200 which allows the distal portion 13426 of the second side plate 13420 to flex with respect to the proximal portion 13422 and accommodate the actuator joint. end piece 13500. The flexible portion 13424 extends laterally from the first side plate 13420 and comprises a hinge including the spans defined therein, which allow rotation within the second side plate 13420. In addition to or instead of the above , the second side plate 13420 comprises longitudinal openings defined therein that allow the second side plate 13420 to flex within the end actuator 13500 and accommodate the hinge of the end actuator 13500. The second side plate 13420 can comprise any number and configuration of openings and / or suitable recesses defined therein in any suitable location that is configured to allow the second side plate 13420 flexes when pivoting the end actuator 13500.

[0270] In addition to the above, the side plates 13410 and 13420 are flexible and can resiliently return to their non-flexed configurations when the end actuator 13500 is returned to its non-articulated configuration. In several cases, side plates 13410 and 13420 comprise springs that resiliently tilt the 13500 end actuator in its non-articulated configuration.

[0271] A 24900 firing member is illustrated in Figures 83 and 84 and can be used with any of the surgical stapling instruments disclosed here. The firing member 24900 comprises a firing bar 24910 which, similar to the above, comprises a plurality of layers. More specifically, the firing bar 24910 comprises two outer layers 24911 and two inner layers 24912. The firing member 24900 further comprises a distal cutting element 24920 which includes a cutting edge of fabric 24926. The distal cutting member 24920 comprises additionally a first cam 24922 configured to engage a first jaw of an end actuator and a second cam 24924 configured to engage a second jaw of the end actuator. That said, modalities are contemplated in which the 24920 distal cutting member is configured to only engage one end actuator jaw or, alternatively, no end actuator jaw.

[0272] Layers 24911 and 24912 of firing bar 24910 are welded to distal cutting member 24920 in welds 24930. As shown in Figure 84, a first weld 24930 is present on a first side of firing member 24900 and a second weld 24930 is present on a second side of firing member 24900. The first weld 24930 penetrates a first outer layer 24911 and the adjacent inner layer 24912. In several cases, the first weld 24930 penetrates entirely through the adjacent inner layer 24912 and / or also penetrates the other inner layer 24912. The second weld 24930 penetrates a second outer layer 24911 and the adjacent inner layer 24912. In several cases, the second weld 24930 penetrates entirely through the adjacent inner layer 24912 and / or also penetrates the other inner layer 24912.

[0273] Referring mainly to Figure 83, each weld

24930 of firing member 24900 comprises a weld line that is configured to firmly secure firing bar 24910 to cutting member 24920 and, at the same time, providing a flexible connection between them. Each 24930 weld comprises a junction weld 24931 that connects cutting member 24920 to the distal ends of plates 24911 and 24912 and is placed under tension and / or compression when a longitudinal firing force is transmitted through the firing member 24900 The junction weld is orthogonal, or at least substantially orthogonal to a longitudinal firing (FA) geometric axis of the firing member 24900. The junction weld 24931 can comprise any suitable configuration, such as a square, square configuration closed, single chamfer, double chamfer, single J, double J, single V, double V, single U, double U, flange, swelling and / or T configuration, for example.

[0274] In addition to the above, each 24930 weld additionally comprises a distal hook weld portion 24932 and a proximal hook weld portion 24933. Each hook weld portion 24932 and 24933 comprises a longitudinal portion that is aligned with , or is parallel to the longitudinal firing (FA) geometry axis of firing member 24900 and is sheared when a longitudinal firing force is transmitted through firing member 24900. In addition, each hook weld portion 24932 and 24933 comprises a joint portion that is orthogonal, or at least substantially orthogonal, to the longitudinal firing (FA) geometric axis and is placed under tension and / or compression when a longitudinal firing force is transmitted through the firing member 24900. Notably, each set of hook weld portions 24932 and 24933 comprises an interlocking connection between firing bar 24910 and cutting member 24920 that can transmit a flow of stress between them without fail and / or causing inadequate performance.

[0275] Each 24930 weld is generally L-shaped, for example; however, 24930 welds can comprise any suitable configuration.

[0276] Although surgical instruments 10000, 11000, 12000, 13000, 14000, 15000, 16000, 17000, 18000, 19000, 20000, 21000, 22000 and 23000 are surgical staplers, their designs can be readily adapted to other surgical instruments that have articulated end actuators, among others. Such other surgical instruments may include, for example, clip applicators, fastener applicators and / or surgical instruments capable of supplying electrical and / or vibrational energy to the tissue.

[0277] Figure 86 shows a surgical staple cartridge 25100 comprising an elongated tip 25150 located at a distal end thereof, generically designated as 25102. The elongated tip 25150 has a base 25152 which is defined by a first length 25154 extending by a distance between the end of the staple line 25056 and a distal tip 25142 of the staple cartridge 25100. The distal tip 25142 is formed at an angle σ from the base 25152 of the staple cartridge 25100. The distal tip 25142 on the clamps 25100 is positioned and configured to serve as a stop area for a wedge slide, not shown, of the trigger system after completing a clamp trigger course.

[0278] In an effort to shorten the overall length of the staple cartridge without sacrificing the length of the stapled tissue, the surgical staple cartridge 25200 shown in Figure 85 comprises a cartridge body 25210 including a shortened tip 25250 located at a distal end thereof, generically designated as 25202. The shortened tip 25250 has a base 25252 which is defined by a second length 25254 that extends a distance between the end of the staple line 25056 and a rounded distal tip 25242 of the staple cartridge

25200. The second length 25254 of the shortened tip 25250 is minimized by dulling the stop area for the wedge slider 25270 (see Figure 89). While the shortened rounded tip 25250 of the staple cartridge 25200 in Figure 85 still provides a stop area for the wedge slider, it may be necessary to make additional accommodation for storage, as will be discussed below. The rounded distal tip 25242 is formed at an angle γ from the base 25252 of the staple cartridge

25200.

[0279] When comparing staple cartridges 25200 and 25100 depicted in Figures 85 and 86, respectively, the reader should recognize that the second length 25254 is shorter than the first length 25154. As a result, the length of the staples 25200 beyond the end of the 25056 staple line is minimized to allow for improved spatial access to a surgical site, among other things. The shortened tip 25250 also prevents the rounded distal tip 25242 from perforating a seal in a trocar system, as is further discussed below. In addition, a person will recognize that the angle γ of the rounded distal tip 25242 of the staple cartridge 25200 with respect to the base 25252 is greater than the angle σ of the sharp distal tip 25142 of the staple cartridge 25100 with respect to the base 25152. For example, the rounded distal tip 25242 can extend at an angle of approximately 45 to 50 degrees from the base 25252 of the staple cartridge 25200, while the sharp distal tip 25142 can extend at an angle of approximately 30 degrees in relative to the base 25152 of the 25100 staple cartridge. The steeper angle of the rounded distal tip 25242 provides increased stability in all distal regions of the 25200 staple cartridge structure.

[0280] Figure 89 is a plan view of the staple cartridge 25200; The cartridge body 25210 of the staple cartridge 25200 comprises an elongated slot 25230 that extends from a proximal end 25204 of the staple cartridge 25200 towards the shortened distal tip 25250. A plurality of staple cavities 25220 are formed within the body of cartridge 25210. Staple cavities 25220 extend between the proximal end 25204 and the distal end 25202 of staple cartridge 25200. Staple cavities 25220 are arranged in six laterally spaced rows 25221, 25222, 25223, 25224, 25225, 25226, with three rows on each side of the elongated slot 25230. Clamps 25260 are removably positioned within clamp cavities 25220.

[0281] Figure 87 illustrates an embodiment of a triple clamp driver 25240 within the clamp cartridge 25200 to support and drive three clamps 25260. Clamp driver 25240 comprises a first driver portion 25342, a second driver portion 25344 and a third portion of driver 25346. A central base member 25348 connects the first portion of driver 25342 and the third portion of driver 25346 to the second portion of driver 25344. The first portion of driver 25342 is positioned at least partially distal to the second portion of driver 25344. Additionally, the third portion of driver 25346 is positioned at least partially distal to the second portion of driver 25344. Several of the first clamp drivers 25240 are slidably mounted within the corresponding clamp cavities 25220 from the three longitudinal rows 25221, 25222, 25223 on one side of the elongated slit 25230. In other words, each first aci clip clamp 25240 is configured to support three clamps 25260: a clamp 25260 stored inside a clamp cavity 25220 in the first longitudinal row 25221; a clip 25260 stored inside a staple cavity 25220 in the second longitudinal row 25222; a clip 25260 stored inside a cavity of clips 25220 in the third longitudinal row 25223. Due to the distal position of the first portion of the driver 25342 and the third portion of the driver 25346 in relation to the second portion of the driver 25344, the clips 25260 are fired in a back arrow setting. As shown in Figure 89, the last clamps 25260 in the first longitudinal row 25221 and in the third longitudinal row 25223 are closer to the shortened tip 25250 of the staple cartridge 25200 than the last clamp 25260 in the second longitudinal row 25222.

[0282] On the other side of the elongated slot 25230, a plurality of second clip drivers are mounted within the corresponding clip cavities 25220 in the three longitudinal rows 25224, 25225, 25226. Similar to the clip driver 25240, each of the seconds Staple actuators comprise a first portion of driver 25342, a second portion of driver 25344 and a third portion of driver 25346. A central base member 25348 connects the first portion of driver 25342 and the third portion of driver 25346 to the second portion of the driver 25344. The first portion of the driver 25342 is positioned at least partially distal to the second portion of the driver 25344. Additionally, the third portion of the driver 25346 is positioned at least partially distal to the second portion of the driver 25344. Just like the staple driver 25240 above , each second clamp trigger is configured to support three 25260 clamps: one 25260 clamp stored in the interior of a staple cavity 25220 in the fourth longitudinal row 25224, a staple 25260 stored inside a staple cavity 25220 in the fifth longitudinal row 25225 and a staple 25260 stored inside a staple cavity 25220 in the sixth longitudinal row 25226. Due at the distal position of the first portion of the driver 25342 and the third portion of the driver 25346 relative to the second portion of the driver 25344, the clamps 25260 are fired in a backward arrow configuration. As shown in Figure 89, the last clamps 25260 in the fourth longitudinal row 25224 and in the sixth longitudinal row 25226 are closer to the shortened end 25250 of the staple cartridge 25200 than the last clamp 25260 in the fifth longitudinal row 25225.

[0283] The first portion 25342 of the staple driver 25240 has a first support column for the front 25352 and a first support column for the back 25354 projecting upwards from a first base of the driver portion. The first front support column 25352 and the first back support column 25354 are spaced apart from one another and collectively form a first clamp support to hold a clamp 25260 in an upright position (ie the clamp pins facing the anvil). Similarly, the second clamp portion 25344 has a second forward support column 25362 and a second back support column 25364 projecting upwardly from a second base of the driver portion. The second back support column 25362 and the second back support column 25364 are spaced apart and collectively form a second clamp support to hold a clamp 25260 in an upright position (ie the clamp pins facing the anvil). The third portion of the driver 25346 has a third support column for the front 25372 and a third support column for the back 25374 projecting upwardly from a third base of the driver portion. The third front support column 25372 and the third rear support column 25374 are spaced from one another and collectively form a third clamp support to hold a clamp 25260 in a vertical position (ie, the clamp pins facing the anvil).

[0284] The center of mass of the first and third portions of the driver 25342, 25346 is represented by the dashed line D-D. Similarly, the dashed line P-P represents the center of mass of the second portion of the 25344 driver. The combined center of mass of the triple clamp driver 25240 is shown in Figures 87 and 88 as the dashed line C-C. As such, the 25240 clamp driver is less likely to roll forward. Notably, C-C is closer to D-D than P-P, which makes the 25240 clip driver very stable.

[0285] As discussed above, the central base member 25348 of the clip driver 25240, shown in Figure 88, attaches the first portion of the driver 25342 and the third portion of the driver 25346 to the second portion of the driver 25344. The central base member 25348 extends laterally between the proximal ends of the first and third backing columns 25354, 25374 in the first and third portions of the driver 25342, 25346, respectively, and the proximal end of the second supporting column forwards 25362 on the second portion of the driver 25344. As can be seen in Figure 90, the central base member 25348 has an angled backward edge 25349 adapted to be engaged by a wedge slide 25270, as will be discussed in further detail below. Due to the extension of the central base member 25348 between all three portions of the driver 25342, 25344, 25346, the midpoint of the rear facing edge 25349 can be bifurcated into a portion that is closest to the first portion 25342 and a portion that is closest to the third portion 25346. Such an arrangement can balance the moments created during firing and the formation of the 25260 staples stored within the staple cavities

25220.

[0286] Referring mainly to Figure 89, each staple cavity 25220 defined in the cartridge body 25210 of the staple cartridge 25200 comprises a proximal wall 25264 and a distal wall 25262. The reverse orientation of the arrow formed by the arrangement of the first, second, and third portions of the driver 25342, 25344, 25346 of the triple clamp driver 25240 discussed above, reduces the forward and / or side scrolling of the clamp driver 25240 during a clamp firing stroke. In several cases, the distal end of the first forward support column 25352 and the distal end of the third forward support column 25372 are pushed into the distal walls 25262 of their respective clamp cavities 25220, which stabilize the actuator 25240. Thus, when the slider 25270 (Figure 89) lifts the clamp driver 25240 upwards during the clamp firing stroke, two distal walls 25262 of the clamp cavities 25220 provide an opposite force against the support columns forward 25352, 25372, preventing any unwanted movement or rolling of the 25240 clamp actuator.

[0287] As shown in Figures 87 to 90, the elongated slot 25230 of the staple cartridge 25200 is configured to receive a portion of a trigger assembly 25280. The trigger assembly 25280 is configured to push the slider 25270 distally to eject the staples 25260 stored inside the staple wells 25220 and deform the staples 25260 against an anvil positioned opposite the staple cartridge 25200. More specifically, a coupling member 25282 pushes the wedge slide 25270 distally from the staple cartridge 25200. The slide in wedge 25270 has four rails, two inner rails 25272 and two outer rails 25274 that are connected to each other by means of a central member 25276. An inner rail 25272 and an outer rail 25274 are positioned on one side of the elongated slot 25230, while the other inner rail 25272 and the other outer rail 25272 are positioned on the opposite side of the elongated slot 25230. When driven distally Then, the inner rails 25272 pass through the inner channels 25212 defined within the body of the cartridge 25210 and engage the rear-facing edge 25349 of the drivers 25240 that support the clamps 25260 to trigger the clamps towards the anvil. Likewise, the outer rails 25274 pass through the outer channels 25214 defined within the cartridge body 25210 and engage the portions of the drivers 25240 that support the clamps 25260 to push the clamps towards the anvil. The distal movement of the wedge slide 25270 causes the rails 25272, 25274 to make contact with the rear facing edges 25349 of the clamp drivers 25240, pushing the clamps 25240 upwards to eject and push the clamps 25260 from the clamp cartridge 25200 in the tissue captured between the staple cartridge 25200 and an opposite anvil. Coupling member 25282 also comprises a cutting edge 25284 that cuts the fabric as coupling member 25282 advances distally to eject the clips 25260 from the cartridge body 25210.

[0288] Again with reference to Figure 87, the positioning of the first, second and third portions of the driver 25342, 25344, 25346 of the clip driver 25240 between or adjacent to an inner rail 25272 and an outer rail 25274 of the wedge slider 25270 provides increased lateral stability. Two rails, an inner rail 25272 and an outer rail 25274, span the clamp driver 25240 to provide greater support and stability for the entire firing stroke. In addition to providing greater stability for the clamp driver 25240, another benefit of having a clamp driver 25240 extending over two rails 25272, 25274 of a wedge slide 25270 is the reduced force required to execute a firing stroke. The required force is reduced because there is less deflection and loss within the system. In addition, the additional drive surface provided by the rear facing edge 25349 allows the rails 25272, 25274 of the wedge slider 25270 to extend at a steeper angle from the base 25278 of the wedge slider 25270. The steeper angle of the slider wedge 25270 allows a general decrease in the length of the base 25278 of the wedge slider 25270, further contributing to the reduction of the length of the shortened tip 25250 of the staple cartridge 25200. After the completion of the staple firing stroke, again with reference to Figure 89, the wedge slide 25270 of the firing assembly 25280 into the shortened tip 25250 of the staple cartridge 25200.

[0289] Figure 89 represents the wedge slide 25270 of the firing set 25280 stopped at the shortened tip 25250 after the completion of the staple firing stroke. The shortened tip 25250 comprises a plurality of openings 25292, 25294 at the distal end of the shortened tip 25250 to receive the four rails 25272, 25274. The shortened tip 25250 further comprises an opening 25296 configured to receive the central sliding member 25276 of the slider in wedge 25270. Thus, the portions of the rails 25272, 25274 and the central sliding member 25276 of the wedge slide 25270 are exposed at the distal end 25202 of the staple cartridge 25200. The openings 25292, 25294 are continuations of channels 25212, 25214 within the which trails

25272, 25274 of the wedge slide 25270 move in a sliding manner. Two Inner openings 25292 are configured to receive the two inner rails 25272 of the wedge slide 25270, while two outer openings 25294 are configured to receive the two outer rails 25274 of the wedge slide 25270. One central opening 25296 in the center of the distal portion 25202 of the shortened tip 25250 is configured to receive the central member 25276 of the wedge slide 25270. The openings 25292, 25294, 25296 at the distal end 25202 of the shortened tip 25250 allow the staple firing stroke to be completed and the wedge slide 25270 to stop at a shortened distal end.

[0290] Again with reference to Figure 89, the staple cartridge 25200 additionally includes projections 25262 that extend around the proximal and distal ends of the staple cavities

25220. Projections 25262 in the first longitudinal row 25221 are shown to be singular, while projections in the second and third longitudinal rows 25222, 25223 are shown to be connected. The 25262 projections are configured to provide additional support for the 25260 clamps as they are fired up and out of their 25220 clamp cavities. In addition, the 25264 projections formed on the most distal clamp cavity 25220 are angled to control the flow of tissue in the end actuator. A more detailed discussion of the projections can be found in US Patent Application Publication 2015/0297228, entitled FASTENER CARTRIDGES INCLUDING EXTENSIONS HAVING DIFFERENT CONFIGURATIONS, filed on June 30, 2014, the description of which is incorporated by reference.

[0291] Figure 91 illustrates some of the benefits obtained from using the shortened staple cartridge 25200 in Figure 85 instead of the extended staple cartridge 25100 in Figure 86. Both staple cartridges are suitable for various surgical procedures, including , for example, low anterior resection (LAR) surgery. LAR is a common treatment, for example, for colorectal cancer. Such procedures require precise dissection and sealing of tissue deep within a patient's pelvic cavity. As will be discussed in more detail below, the reduced length of the staple cartridge 25200 due to the reduced tip 25250 in Figure 85, among other things, allows the surgical instrument end actuator to gain greater access to tissue in the pelvic cavity. The reader should understand that the staple cartridges described herein can be used in various surgical treatments and should not be limited by the specific procedures discussed in the present invention.

[0292] In addition to the above, the staple cartridge 25200 is part of a first end actuator 25202 in a first surgical instrument 25201, which also includes an anvil

25203. The first surgical instrument 25201 additionally comprises a first drive shaft 25206 which is pivotally connected to the first end actuator 25202. The first end actuator 25202 is articulated around a joint 25208 positioned between the first end actuator 25202 and the first drive shaft 25206. The first end actuator 25202 is capable of being pivoted at an angle α relative to the first drive shaft 25206. Similarly, the elongated clamp cartridge 25100 is part of a second end actuator 25102 on a second surgical instrument 25101 which also includes an anvil 25103. Also, the second surgical instrument 25101 additionally comprises a second drive shaft 25106 which is pivotally connected to the second end actuator 25102. The second end actuator 25102 is pivotable around a 25108 pivot joint positioned between and the second end actuator 25102 and the second drive shaft 25106. The second end actuator 25102 is capable of being pivoted at an angle β with respect to the second drive shaft 25106.

[0293] In addition to the above, in use, the physician inserts the 25202 end actuator through a cannula, or trocar, and into a patient when the 25202 end actuator is in its non-articulated condition. Once through the trocar, the end actuator 25202 can be articulated as shown in Figure

91. At such a point, the drive shaft 25206 can be moved to position the end actuator 25202 in the pelvic cavity. Similar steps would be used to position the end actuator

25102.

[0294] The first end actuator 25202 is capable of reaching an X1 distance from the pelvic floor within the pelvic cavity during an LAR procedure. The second end actuator 25102 is capable of reaching an X2 distance from the pelvic floor within the pelvic cavity during an LAR procedure. The distance X1 is shorter than the distance X2, allowing the first surgical instrument 25201 to be placed more deeply in the pelvic cavity than the second surgical instrument 25101, giving the surgeon the ability, among other things, to target, access and remove a larger matrix of diseased tissue from the colon. In addition, the articulation capabilities of the first 25201 surgical instrument allow deeper access to tissue within the surgical site while inflicting minimal trauma to the surrounding tissue. The first end actuator 25202 is capable of being articulated to a greater degree than the second end actuator 25102, since β is greater than α. For example, the first end actuator 5202 can be pivoted to an angle 115 degrees from the first drive shaft 25206, while the second end actuator 2 can be pivoted only to an angle 135 degrees from the second drive shaft 25106 .

[0295] As shown in Figure 91, staple cartridge 25100 and anvil 25103 of end actuator 25102 are approximately the same length, but staple cartridge 25100 is noticeably longer than anvil 25103. Comparatively, the staple cartridge 25200 and the anvil 25203 of the end actuator 25202 are of substantially the same length, if not the same length. In any case, the difference in length between the staple cartridge 25200 and the anvil 25203 of the end actuator 25202, if any, is much smaller than that of the end actuator 25102.

[0296] An extreme difference between the distal end of a staple cartridge and the distal end of an anvil can cause damage to a trocar when the end actuator is inserted through it. Referring to Figure 92, an end actuator 25810 comprises a distal end 25802, an anvil 25820 and a staple cartridge 25830. Staple cartridge 25830 has a shortened and rounded nose 25840 similar to the shortened nose 25250 over the shortened cartridge clamps 25200 in Figure 85. As can be seen in Figures 92 and 93, anvil 25820 has a protective tip 25822 on it. Protective tip 25822 is sized and positioned over anvil 25820 in a way that makes anvil 25820 shorter in length than the staple cartridge 25830. Thus, the shortened tip 25840 of the staple cartridge 25830 extends distally with respect to anvil 25820. Protective tip 25822 may be integrally formed (molded, machined, etc.) on the distal end 25802 of anvil 25820 or may comprise a separate part configured to receive a complementary portion of the anvil. A more detailed discussion of the protective tips can be found in US Patent Application Publication 2008/0169328, entitled IMPROVED BUTTRESS MATERIAL FOR USE WITH A SURGICAL STAPLER, whose full description is hereby incorporated by reference in its entirety for reference.

[0297] As can be seen in Figures 92 and 93, the protective tip 25822 of the anvil 25820 has a first curved or angled outer surface 25824, and a second curved or angled outer surface 25826 configured to form a stubby distal end over the anvil 25820 The first angled outer surface 25824 extends downwardly from a top surface 25828 of the anvil 25820 at a first angle φ. The second angled outer surface 25826 extends downwardly from the first angled outer surface 25824 towards the staple cartridge 25830 at a second angle θ. The second angle θ is greater than the first angle φ. Several modalities are predictions in which the angle θ measures, for example, approximately 90 degrees. Other modalities of the protective tip 25822 are provided for having only one of a first inclined external surface 25824 or a second inclined external surface 25826. The first inclined external surface 25824 serves to deflect a centering ring from a trocar seal assembly during insertion of the end actuator 25810 through the trocar. When the second angle θ is 90 degrees apart, and / or when the first and second curved outer surfaces 25824, 25826 are not continuous, the anvil 25820 can pierce through a trocar seal or it can displace the centering ring from one trocar sealing system, as will be discussed in more detail below.

[0298] A protective tip can be attached to an anvil in any suitable way. Figures 94 to 99 illustrate exemplary modalities of protective tips formed separately 25922, 26022, and various methods for attaching them to an anvil. As shown in Figures 94 to 96, a distal portion of an anvil 25920 comprises a fixing feature that includes fixing members 25927, 25929 that are configured to fit retentively with the complementary retaining channels 25926, 25928 formed on the protective tip 25922. More specifically, a central retaining channel 25928 is formed within the protective tip 25922 to receive a central fixing member 25929 of the anvil

25920. A pair of lateral retaining channels 25296 is formed within the protective tip 25922 to receive a pair of corresponding lateral fixing members 25927 on anvil 25920. Figure 96 is a cross-sectional view of anvil 25920 of Figure 94 taken along from line 96-96 in Figure 95 in a disassembled configuration showing the alignment of the retention channels 25926, 25928 with their respective fixing members 25927, 25929. An elongated slot 25994 extends longitudinally from the proximal end 25904 of the anvil 25920 towards the distal end 25902 of the anvil 25920. The elongated slot 25994 is configured to receive a portion of the firing set discussed here.

[0299] In addition, or alternatively to the above, the protective tip 25922 can be attached to the anvil 25920 using the rivets

25924. As shown in Figure. 96, a through hole 25925 extends through the central retaining channel 25928 of the protective tip

25922. A through hole 25925 also extends through the central fixing member 25929 of the anvil 25920 so that when the protective tip 25922 is attached to the anvil 25920, the through holes 25925 align to facilitate the insertion of a rivet 25924 therein. THE

Figure 95 is a cross-sectional view of anvil 25920 represented in Figure 94 taken along line 95-95 in Figure 94 in a disassembled configuration illustrating a rivet assembly for removably securing protective tip 25922 to anvil 25920 In addition, or alternatively to the above, the protective tip 25922 can be fixed to the anvil 25920 by means of adhesives such as, for example, cyanoacrylates, light-curable acrylics, polyurethanes, silicones, epoxies and / or ultraviolet-curable adhesives. , such as HENKEL LOCTITE®. In any case, a combination of fixing members and retaining channels can be provided on the anvil 25920 and the protective tip 25922. Still other forms of fixations and fixing arrangements can be used to fix the protective tip 25922 to the anvil 25920 .

[0300] Figures 97 to 99 illustrate another embodiment of a tip attachment arrangement. A distal portion of an anvil 26020 comprises fixing members 26027 which are configured to fit retentively with the complementary retaining channels 26026 defined in the protective tip 26022. In addition, a central retaining channel 26028 defined within the protective tip 26022 is configured to receive a central fixing member 26029 of anvil 26020. Figure 98 is a cross-sectional view of anvil 26020 of Figure 97 taken along line 98-98 in Figure 97 in a disassembled configuration showing the alignment of the retaining channels 26026, 26028 with their respective fixing members 26027, 26029. Figure 99 is a cross-sectional view of anvil 26020 in Figure 97, taken along line 99-99 in Figure 97 in an assembled configuration. Protective tip 26022 is attached to the 26020 anvil using a compression fitting. The central fixing member 26029 is pressed into the central retaining channel 26028, remaining in place due to the geometry of the central retaining channel 26028. The central fixing member 26029 of the anvil 26020 in Figure 98 has a trapezoidal shape that is imitated by the central retention channel 26028. An elongated slot 26094 extends longitudinally from a proximal end 26004 of the anvil 26020 towards the distal end 26002 of the anvil 26020. The elongated slot 26094 is configured to receive a portion of the firing set discussed herein.

[0301] In addition, or alternatively to the above, the protective tip 26022 can be fixed to the anvil 26020 by means of adhesives such as, for example, cyanoacrylates, light-curable acrylics, polyurethanes, silicones, epoxies and / or ultraviolet curable adhesives , such as HENKEL LOCTITE®. In various embodiments, a combination of fixing members and retaining channels can be provided on the 26020 anvil and the 26022 protective tip. Still other forms of fixations and fixing arrangements can be used to fix the 26022 protective tip to the 26020 anvil. Figures 97 to 99 additionally illustrate means to assist a user in fixing the protective tip 26022 to the anvil 26020. Figure 97 illustrates the protective tip 26022 positioned removably within a temporary support 26030. In order to releasably secure the protective tip 26022 to anvil 26020, the user presses the temporary support 26030 and the anvil 26020 together. The temporary support 26030 can provide an additional sterilization barrier to the protective tip 26022 while the protective tip 26022 is attached to the anvil 26020. In addition, the temporary support 26030 provides the user with an object that is more substantial to hold when fixing the protective tip 26022 to anvil 26020, since the protective tip 26022 may be small in size. It is envisaged that the temporary support 26030 can be used in various modalities of protective tips, including in the other modalities presented in the present invention.

[0302] Various protective anvil tips have been described and shown in the present invention as being used in conjunction with a linear end actuator. Those skilled in the art will readily understand, however, that the protective anvil tips described herein can be used together with a variety of different end actuator configurations, such as curved end actuators and other types of end actuators without moving away the spirit and scope of this description. Thus, the protective tip described above should not be limited to use only in conjunction with linear end actuators and / or staplers.

[0303] Figures 100 to 106 illustrate an exemplary practical application of the various end actuators described here when they are inserted through a trocar seal system before being introduced into a surgical site. The trocar seal system 27040 of Figures 100 to 106 comprises a housing 27042 configured to support a floating seal assembly 27050 and a central opening 27044 configured to receive a surgical instrument. The floating seal assembly 27050 comprises a first seal port 27052 and a second seal port 27054 that work together to prevent gas from escaping from an inflated cavity in a patient during a surgical procedure. The floating seal assembly 27050 additionally comprises a centering ring 27058 which is configured to guide a surgical instrument through the central opening 27044 of the 27040 trocar seal system. The 27050 floating seal assembly is attached to the 27042 housing of the trocar seal 27040 through a resilient annular element 27056.

[0304] Figure 100 shows an example end actuator 27000 comprising an anvil 27010 and a staple cartridge 27020. The staple cartridge 27020 comprises a shortened and rounded nose 27022 similar to the shortened nose 25250 shown in the staple cartridge 25200 in Figure 85. The distal end 27202 of anvil 27010 is pointed and does not have a protective tip, as shown in Figure 92. As can be seen in Figure 100, anvil 27010 is shorter in length than the staple cartridge 27020 In other words, the shortened tip 27022 of the staple cartridge 27020 extends longitudinally beyond the distal end 27002 of the anvil 27010. Before insertion of the end actuator 27000 through the trocar seal system 27040, the first seal port 27052 and the second sealing port 27054 extends inward to prevent gas from escaping from the surgical site. Figure 101 represents the 27000 end actuator of Figure 100 partially inserted in the 27040 trocar seal system. The shortened tip 27022 of the 27020 staple cartridge is the first component of the 27000 end actuator to come into contact with the first and second sealing ports 27052, 27054 of the 27040 trocar seal system, tilting the floating seal assembly 27050 to one side. Due to its rounded shape, the shortened tip 27022 does not damage the second seal port 27054 despite exerting a force on it.

[0305] Figure 102 represents the end actuator 27000 of Figures 100 and 101 when the end actuator 27000 was additionally introduced into the central opening 27044 of the trocar seal system 27040. After the initial contact of the shortened staple cartridge tip 27022 with the 27040 trocar seal system, the pointed distal end 27002 of the anvil 27010 comes into contact with the first seal port 27052 of the 27040 trocar system. In many cases, the pointed distal end 27002 of the anvil 27010 may break the first seal port 27052 of the trocar seal system 27040 As the contact between the shortened tip 27022 and the second seal port 27054 has already changed the position of the floating seal assembly 27050, laterally. As shown in Figure 103, if the distal end 27002 of anvil 27010 comprised a protective tip 27012 similar to the protective tip 25822 shown in Figure 92, the risk of rupture of the first seal port 27052 would be reduced. The risk of breakage decreases with the use of a 27012 protective tip on the 27010 anvil, as the first seal port 27052 stretches smoothly around the protective tip 27012. In addition, the same length of the cartridge and anvil reduces, or prevents, pre-displacement of the floating seal assembly.

[0306] Figure 104 shows an example actuator end 27100 comprising an anvil 27110 and a staple cartridge 27120. The staple cartridge 27120 comprises an elongated and pointed nose 27122 similar to the elongated nose 25150 shown in the staple cartridge 25100 in Figure 86. The distal end 27102 of anvil 27110 is pointed and does not have a protective tip, like the one shown in Figure 92. Anvil 27110 has a shorter length than the staple cartridge 27120. In other words, the elongated tip 27122 of staple cartridge 27120 extends longitudinally beyond the distal end 27102 of the anvil

27110. Prior to insertion of the 27100 end actuator through the trocar40 seal system 27040, the first seal port 27052 and the second seal port 27054 of the trocar seal system 27040 extend inward to prevent gas from escaping from the surgical site. Figure 105 represents end actuator 27100 of Figure 104 when end actuator 27100 is initially inserted into the trocar seal system 27040. The elongated tip 27122 of staple cartridge 27120 is the first component of end actuator 27000 to come into contact with contact with the first and second sealing ports 27052, 27054 of the 27040 trocar seal system by tilting, or pre-shifting, the 27050 floating seal assembly to one side, as discussed above.

[0307] Figure 106 represents the end actuator 27100 of Figures 104 and 105 when the end actuator 27100 was additionally introduced into the central opening 27044 of the trocar seal system 27040. After the initial contact of the elongated tip 27100 of the staple cartridge 27120, the pointed distal end 27102 of the anvil 27110 comes into contact with the first seal port 27052 of the trocar seal system 27040. In several cases, the pointed distal end 27102 of the anvil 27110 may break the first seal port 27052 of the system Trocar seal 27040 as the contact between the elongated tip 27122 and the second seal port 27054 displaced the position of the 27050 floating seal assembly.

[0308] As discussed in the present invention, a first staple cartridge may comprise a first cartridge length and a second staple cartridge may comprise a second cartridge length that is different from the first cartridge length. In several cases, an end actuator of a surgical stapling instrument may comprise a cartridge gripper configured to receive the first staple cartridge and, in an alternative embodiment, the second staple cartridge. In other words, the cartridge gripper is configured to receive the first staple cartridge and the second staple cartridge, but not at the same time. The first staple cartridge and the second staple cartridge individually comprise a proximal end that is aligned with a detail of the proximal cartridge jaw when it is positioned on the cartridge jaw. When the first length of the cartridge is longer than the second length of the cartridge, for example, the distal end of the first staple cartridge would be positioned further from the detail of the proximal cartridge jaw given the distal end of the second staple cartridge. The reader should understand that the second cartridge length may be longer than the first cartridge length in other cases.

[0309] In addition to the above, the end actuator comprises a movable anvil claw relative to the cartridge claw between an open, or not clamped, position and a closed, or clamped position. In alternative embodiments, the jaw of the cartridge is movable in relation to the jaw of the anvil. In any case, the anvil claw comprises a distal anvil end that is supported by the first staple cartridge and the second staple cartridge, depending on which staple cartridge is positioned in the cartridge claw. The distal anvil end is supported at a first location on the first cartridge jaw and at a second location on the second cartridge jaw. In many cases, the first location and the second location may not be at the same distance from the detail of the given proximal cartridge grip. In some cases, however, they may be at the same distance from the detail of the given proximal cartridge grip. In addition, in several cases, the first location is located at a first distance from the distal end of the first staple cartridge while the second location is located at a second, or different, distance from the distal end of the second staple cartridge. In use, a patient's tissue will be positioned between the anvil clamp and the cartridge claw but, however, the support locations of the staple cartridges will still support the anvil claw, or the fixation load applied by the anvil claw.

[0310] In several cases, in addition to the above, the distal anvil end may extend distally beyond the distal end of the first staple cartridge when the end actuator is in a closed configuration and the first staple cartridge is positioned in the grip of the cartridge and, similarly, the distal end of the anvil may extend distally beyond the distal end of the second staple cartridge when the end actuator is in a closed configuration and the second staple cartridge is positioned in the cartridge grip. . However, when the first cartridge length is longer than the second cartridge length, in many cases, the distal anvil tip may extend distally beyond the distal end of the second staple cartridge, but may not extend distally beyond the distal end of the first staple cartridge. In such cases, the anvil claw may be longer than the second staple cartridge when the second staple cartridge is positioned in the cartridge claw, but shorter than the first staple cartridge when the first staple cartridge is positioned on the cartridge grip. In some cases, the anvil claw is the same length as the first staple cartridge or the second staple cartridge.

[0311] In addition to the above, the anvil claw will deflect when it moves to its closed position. Due to the different cartridge lengths of the staple cartridges, the deflection of the anvil claw can be different depending on which staple cartridge is positioned in the cartridge claw. As a result, the staple gap between the anvil clamp and the staple actuators of the first claw of the cartridge may be different from the staple gap between the anvil clamp and the staple actuators of the second claw cartridge. In some cases, the gap in the staple formation gap is negligible, and the staples ejected from the first staple cartridge and the second staple cartridge will be formed at the same height, or at least at the lowest suitable and sufficient heights for staple the fabric caught between the anvil claw and the cartridge claw. In such cases, the unformed height of the clamps on the first clamp cartridge can be equal to the unformed height of the clamps on the second clamp cartridge. In other cases, the unformed height of the clamps on the first clamp cartridge is different from the unformed height of the clamps on the second clamp cartridge. In such cases, the higher staples can be used on the first staple cartridge and the shorter staples can be used on the second staple cartridge, for example, depending on the deflection and / or anticipated orientation of the anvil claw when closed against the first and the second staple cartridges. In at least one of these cases, each of the staples in the first staple cartridge has an unformed height in a first unformed height range and each of the staples in the second staple cartridge has an unformed height in a second height range not formed. In some cases, the first unformed height band is completely different from the second unformed height band while in other cases, the first unformed height band partially overlaps the second unformed height band.

[0312] As discussed above, the first staple cartridge and the second staple cartridge are selectively positioned on the end actuator's cartridge jaw and, in addition to the above, the cartridge jaw additionally comprises a support or bottom surface configured for support the staple cartridges when they are seated on the cartridge gripper. Such support may include a vertical detail. In several cases, the first support location on the first staple cartridge and the second support location on the second staple cartridge, discussed above, have the same vertical distance from the vertical detail of the cartridge grip. The vertical distance is measured orthogonally from the vertical reference, but it can be measured in any suitable way.

In such cases, the orientation and / or deflection of the anvil claw when the anvil claw is in its secured position may be different as a result of the first local support location and the second support location having different vertical heights. Such different vertical heights can occur when the distal end, or tip, of the first staple cartridge, is different from the distal end of the second staple cartridge, among other reasons.
