BR112019027695A2 - surgical instruments with constricted claws to rotate around a geometric axis through contact with a closing member that is parked in close proximity to the pivot geometric axis - Google Patents

Abstract

The present invention relates to a surgical instrument that includes an elongated drive shaft assembly that defines a drive shaft geometric axis and includes a first jaw attached to it. A second jaw is coupled to the first jaw for selective pivoting displacement in relation to it between a completely open position and a completely closed position around a claw pivot geometry axis that is transversal to the drive axis geometry and extends through the same. The elongated drive shaft assembly includes a closing member that is axially movable between an initial position which corresponds to the fully open position and an end position which corresponds to the fully closed position. When the closing member is in the starting position, a distal end of it is situated on a plane that is separated distally from the claw pivot geometry axis at a distance that is measured along the drive axis geometry which is no longer than 0.090 inch.

Likewise, an element of a surgical system, device or device that "comprises", "has", "includes" or "contains" one or more resources has those one or more resources, but is not limited to possess only those one or more resources.

[0113] The terms "proximal" and "distal" are used in the present

intervention with reference to a doctor who handles the handle portion of the surgical instrument. 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.

[0114] Several exemplary devices and 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 numerous 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's 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 shaft long drive of a surgical instrument can be advanced.

[0115] The surgical stapling system may 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 gripper; however, other modalities are provided for in which a staple cartridge is not removable, or at least promptly 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 in relation to the first claw around a geometric axis of the cover; 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 geometric pivot axis that extends through the pivot joint. Other modalities are foreseen that do not include an articulation joint.

[0116] 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 a first side of the fabric to be stapled and the anvil is positioned on a second side of the fabric. The anvil is moved towards the staple cartridge to compress and hold 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 are 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 staple cavity and staple arrangements may be possible.

[0117] The clamps are supported by clamp 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 movable between their non-triggered positions and their positions triggered by a slider. The slide is movable between a proximal position adjacent to the proximal end and a distal position adjacent to the distal end. The slide comprises a plurality of inclined surfaces configured to slide under the actuators and lift the actuators, and the staples supported on it, towards the anvil.

[0118] 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 also comprises a first cam that engages with the first claw and a second cam that engages with 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 staples are ejected in front of the knife.

[0119] Figure 1 depicts a motor-driven surgical system that can be used to perform a variety of different surgical procedures. As can be seen in that Figure, an example of surgical system 10 includes four sets of interchangeable surgical tools 1000, 3000, 5000 and 7000 that are adapted for interchangeable use with a handle set 500. Each set of interchangeable surgical tools 1000, 3000, 5000 and 7000 can be designed for use in connection with the performance of one or more specific surgical procedures. In another type of 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.

[0120] 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 set of handle 500 in a similar manner. The fixation arrangement and process shown in Figure 2 can also be used in connection with the attachment of any of the interchangeable surgical tool sets 1000, 3000, 5000 and 7000 to a tool drive portion or tool drive housing for a robotic system. The handle assembly 500 may comprise a handle housing 502 that includes a pistol handle 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.

[0121] 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 way, the locking drive system 510 may include an actuator in the form of a locking trigger 512, articulated by the 506 handle structure. This arrangement allows the closing trigger 512 is handled by a physician, so that when the physician grips the pistol grip assembly portion 504 of the grip assembly 500, the closing trigger 512 can be easily rotated from an initial position or " not actuated "to an" actuated "position and, more particularly, to a completely compressed or fully acted position. 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 makes an operational interface 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 handle 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 into the present invention, when the physician presses the closing trigger 512 completely to When reaching a full closing stroke, the closing drive system 510 is configured to lock the closing trigger 512 in the fully depressed or fully actuated position. When the doctor wants to unlock the closing trigger 512 to allow it to be propelled to the unacted position, the doctor simply activates a set of closing release button 518 that allows the closing trigger to return to the position not 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. A further discussion regarding configuration and The operation of the closing release button set 518 can be found in US Patent Application Publication No. 2015/0272575.

[0122] 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 trigger drive system 530 may employ an electric motor 505 which is located in the pistol grip portion 504 of the grip assembly 500. In various forms, the 505 motor can be a brushed DC 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, power source 522 can be replaceable and / or rechargeable.

[0123] The 505 electric motor is configured to axially drive a longitudinally movable drive member (not shown) in the distal and proximal directions depending on the polarity of the motor. For example, when the motor is started in a rotating direction, the longitudinally movable drive member will be axially driven in a distal "DD" 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 ( not shown) that are configured to detect the position of the drive member and / or the direction in which the drive member is being moved. The motor drive can be controlled by a trigger trigger 532 (Figure 1) pivotally supported on 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 doctor releases the trigger trigger 532, it can be rotated or, otherwise, returned to the unactivated position by means of the spring or the bias arrangement. In at least one way, the trigger trigger 532 can be positioned "distant" from the closing trigger 512, as discussed above. As discussed in US Patent Application Publication 2015/0272575, the handle set 500 can be equipped with a trigger trigger safety button (not shown) to prevent inadvertent trigger trigger 532. When the closing trigger 512 is in the non-actuated position, the safety button is contained in the handle set 500, where the doctor cannot readily access it and move it between a safety position, which prevents the actuation trigger trigger 532, and a trigger position at which trigger trigger 532 can be fired. When the doctor presses the lock trigger 512, the safety button and the trigger trigger 532 pivot down to a position where they can then be manipulated by the doctor.

[0124] In at least one shape, the longitudinally movable drive member may have a toothed rack (not shown) formed thereon for engagement with a corresponding drive gear arrangement (not shown) that forms - terface with the engine. Additional details regarding those features can be found in US Patent Application Publication 2015/0272575. At least one shape also includes a manually actuated "retraction" set, which is configured to allow the physician to manually retract the longitudinally movable drive member, in case the 505 engine stops running. The retract assembly may include a retract lever or handle assembly that is stored inside the handle assembly 500 under a removable door 550. See Figure 2. The lever can be configured to be manually hinged in engagement. ratchet with teeth on the drive member. In this way, the physician can manually retract the drive member 540 using the retraction handle assembly to engage the drive member 540 in the proximal "PD" direction. US Patent No. 8,608,045, entitled POWE-RED SURGICAL CUTTING AND STAPLING APPARATUS WITH MA- NUALLY RETRACTABLE FIRING SYSTEM, the description of which is incorporated herein by reference in the present invention, discloses rescue provisions and other components, provisions and systems that can also be used with any of the various interchangeable surgical tool sets disclosed in the present invention.

[0125] 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 The gripper comprises an elongated channel 1602 that is configured to operationally support a 1700 surgical staple / clamp cartridge inside. 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 release the surgical end actuator 1500 in a desired articulated position relative to a geometric axis of the SA drive axis. More details regarding the articulation system and the articulation lock can be found in the US patent application entitled SURGICAL INSTRUMENT COM- PRISING AN ARTICULATION SYSTEM LOCKABLE TO A FRAME, with proxy document number END8217USNP / 170102, filed on the same date and incorporated by reference to the present invention in its entirety.

[0126] As can be seen further in Figures 4 and 7 to 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 nozzle assembly 1240 comprises nozzle portions 1242, 1244, as well as a wheel portion of the actuator 1246 which is configured to be coupled to the portions of the assembled nozzle 1242, 1244 by pressure fittings, pins, screws, etc. . The interchangeable surgical tool set 1000 includes a proximal closing assembly 1900 that is operationally coupled to a distal closure assembly 2000 that is used to close and / or open the anvil 1810 of the surgical end actuator 1500, as will be further discussed in more detail below. In addition, the interchangeable surgical tool kit 1000 includes a central column assembly 1250 that operationally supports the proximal closure assembly 1900 and is coupled to the surgical end actuator

1500. In various circumstances, to facilitate assembly, the back assembly 1250 can be manufactured from a upper back segment 1251 and a lower back segment 1252 that are interconnected together by snap-on, adhesive, solder features , etc. In assembled form, the dorsal assembly 1250 includes a proximal end 1253 that is pivotally supported on the tool chassis 1210. In one arrangement, for example, the proximal end 1253 of the central column assembly 1250 is attached to a dorsal bearing (not shown) which is configured to be supported within the tool chassis

1210. This arrangement facilitates the swiveling fastening of the dorsal assembly 1250 to the tool chassis 1210, so that the dorsal assembly 1250 can be selectively rotated around a geometric axis of the drive shaft SA; in relation to the tool chassis 1210. In particular, in an arrangement, for example, the proximal end 1253 of the dorsal assembly 1250 includes an upper pin fitting 1254 (Figures 4,5,7,8e 10) and a lower pin fittings (not shown) that are individually configured to receive a corresponding nozzle pin 1245 extending inwardly from each of the nozzle portions 1242, 1244. This arrangement facilitates rotation of the central column 1250 around the geometric axis of the drive axis SA; by rotating the wheel portion of actuator 1246 of nozzle assembly 1240.

[0127] 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 shaft segment of the middle central column 1256 of the upper back segment 1251 ends in a top pin crimp feature 1260 and the middle shaft drive segment of the lower back segment 1252 ends in a bottom pin crimping feature 1270. As can be seen more particularly in Figure 6, for example, the top pin crimping feature 1260 is formed with a pin slit 1262 in it that is adapted to passably support a mounting link higher than 1264 on it. Similarly, the lower pin crimping feature 1270 is formed with a pin slot 1272 in it which is adapted to mount a lower mounting link 1274 in a passable way. The upper mounting link 1264 includes a pivot socket 1266 inside which is offset from the geometric axis of the drive shaft SA. The pivot socket 1266 is adapted to pivot a pivot pin 1634 on it which is formed on a channel cover or anvil retainer 1630 which is attached to a proximal end portion 1610 of the elongated channel 1602. The lower mounting link 1274 includes the lower pivot pin 1276 which is adapted to be received inside 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 the pivot 1611, it is offset in relation to the geometric axis of the drive axis SA. The lower pivot pin 1276 is vertically aligned with the pivot socket 1266 to define a geometric axis of articulation AA; around which the surgical end actuator 1500 can pivot in relation to the SA drive shaft. Although the hinge axis AA: is transversal to the hinge axis of the SA drive shaft, the hinge axis AA; it is moved laterally from it and does not cross the geometric axis of the drive axis SA.

[0128] Now with reference to Figures 6 and 15, the anvil 1810 in the illustrated example includes a body and anvil 1812 that ends at the anvil mounting portion 1820. The anvil mounting portion 1820 is movably supported or hinged in the channel elongated 1602 for selective pivoting displacement in relation to it around a fixed anvil pivot geometric axis PA: (FIGURE 15) which is transversal to the geometric axis of the drive axis SA :. In the illustrated arrangement, a pivot member or rotating pin of anvil 1822 extends laterally on either side of the mounting portion of the anvil 1820 to be received on a base of corresponding rotating pins 1614 formed on the vertical walls 1612 of the proximal end portion 1610 of the elongated channel 1602. The rotating pins of the anvil 1822 are pivotally retained at their bases of corresponding rotating pins 1614 by the channel cover or anvil retainer 1630. The channel cover or the anvil retainer 1630 includes a pair of fixing pins 1636 which are configured to be received retentively within the corresponding grooves or pin notches 1616 formed in the vertical walls 1612 of the proximal end portion 1610 of the elongated channel 1602.

[0129] In the illustrated example, the surgical end actuator 1500 is selectively articulable around the geometric axis of articulation AA: by the articulation system 1300. In one form, the articulation system 1300 includes the proximal articulation actuator 1310 that it is pivotally coupled to a hinge link 1320. As can be seen more particularly in Figure 6, an offset fixation pin 1314 is formed at a proximal end 1312 of the proximal hinge pin 1310. A pivot hole 1316 is formed on the displaced fixing pin 1314 and is configured to pivotally receive a proximal link pin 1326 formed at the proximal end 1325 of the link link 1320. A distal end 1322 of the link link 1320 includes a pivot hole 1324 which is configured to receive, articulatively 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 thus apply articulation movements to the elongated channel 1602 to thereby cause the surgical end actuator 1500 to articulate about the geometric axis of articulation AA, in relation to the set of central column 1250.

[0130] 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, in the illustrated arrangement, the proximal closure assembly 1900 comprises a proximal closure tube 1910 that has a proximal closure tube portion 1920 and a distal portion 1930. The portion distal 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 swiveled in a reciprocating closing element 1940 which is supported in an off-center manner within the tool frame 1210, so that it can move axially in it. In one form, the reciprocating closing element 1940 includes a pair of hooks that protrude proximally 1942 that are configured for fixing to the fixing pin 516 which is fixed to the closing hinge assembly 514 of the handle assembly 500. The proximal end 1922 of the proximal closing tube portion 1920 is coupled to the reciprocating closing element 1940 for relative rotation with respect to it. 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 slots 1946 in the reciprocating closing element 1940. This arrangement serves to secure the proximal closing 1900 to the reciprocating closing element 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 drive shaft SA :. A closing spring 1948 (Figures 12 to 14) extends over the portion of the proximal closing tube 1920 to propose the reciprocating closing element 1940 in the proximal direction PD that can serve to articulate the closing trigger 512 on the set of handle 500 (Figure 2) to the unacted position when the interchangeable surgical tool set 1000 is operationally coupled to the handle set 500.

[0131] 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. In the illustrated arrangement, for example, the distal closing assembly 2000 includes a connector for joint 2010 which is coupled to a 2030 distal closing tube segment. In the illustrated example, the 2030 distal closing tube segment has a diameter that is larger than the diameter of the distal portion 1930 of the 1910 proximal closing tube. The hinge connector 2010 has a proximally extending end portion 2012 that is adapted to be received on a 1934 connecting flange formed at the distal end of the distal portion 1930. The hinge connector 2010 can be retained on the flange 1934 connector by a suitable fastener arrangement, such as an adhesive, welding, etc. The hinge connector 2010 includes the upper and lower latches 2014, 2016, projecting distally from a distal end of the hinge connector 2010 to be mobilely coupled to a closing sleeve of the end actuator or distal segment of the closing tube 2030. The distal segment of the closing tube 2030 includes an upper lock 2032 and a lower lock (not shown) that project 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 distal closing tube segment 2030, respectively. Similarly, a lower double pivot loop 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.

[0132] In at least one arrangement, the interchangeable surgical tool set 1000 additionally includes a firing system generally designated as 2100. In the illustrated example, firing system 2100 includes a firing member set 2110 that is supported for the axial displacement within the central column assembly 1250. In the illustrated embodiment, the firing member assembly 2110 includes an intermediate portion of the firing drive shaft 2120, which is configured to connect to a distal cutting portion or bar cutter 2130. The firing member assembly 2110 may 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 can be dimensioned and configured to allow relative movement between them and may comprise a sliding joint

2134. Sliding joint 2134 may allow the intermediate firing drive shaft portion 2120 of firing member assembly 2110 to be 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 bar cutter 2130 in order to advance the cutter bar 2130 and fire the surgical staple / clamp cartridge 1700 positioned inside the elongated channel 1602. In the illustrated arrangement, a proximal end 2127 of the trigger drive shaft portion intermediate 2120 has a firing pin for the firing drive shaft 2128 formed on it (Figure 8) which is configured to be seated on a coupling base (not shown) that is on the distal end of the longitudinally movable drive (not shown) of the trigger drive system 530 within the cable assembly 500. This arrangement facilitates the axial movement of the portion of the drive drive shaft intermediate frame 2120 through the activation of the triggering system 530.

[0133] In addition to the above, the interchangeable tool set 1000 can include a 2200 gear set, which can be configured to selectively and releasably connect the proximal drive driver 1310 to the trigger member 2100 In one form, gearshift assembly 2200 comprises a locking ring or locking sleeve 2210 positioned around the intermediate firing drive shaft portion 2120 of firing system 2100, where locking sleeve 2210 can be rotated between a engaged position in which the locking sleeve 2210 couples the proximal pivoting actuator 1310 to the trigger member 2110 and a disengaged position, where the proximal pivoting actuator 1310 is not operably coupled to the firing member assembly

2110. When the locking sleeve 2210 is in its engaged position, the distal movement of the firing member assembly 2110 can move the proximal articulation actuator 1310 distally and, correspondingly, the proximal movement of the firing member assembly. 2110 can proximally move the proximal articulation trigger

1310. When the locking sleeve 2210 is in its disengaged position, the movement of the firing member 2110 is not transmitted to the proximal pivoting actuator 1310 and, as a result, the firing member 2110 can move. independently of the proximal articulation actuator 1310. In many circumstances, the proximal articulation actuator 1310 can be held in position by the articulated lock 1400 when the proximal articulation actuator 1310 is not being moved in the proximal or distal direction by the member assembly of firing 2110.

[0134] In the illustrated arrangement, the intermediate firing drive shaft portion 2120 of the firing member assembly 2110 is formed with two opposite flat sides 2121, 2123 with a driving notch 2126 formed therein. 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 drive shaft portion of intermediate trigger 2120 through it. The locking sleeve 2210 can comprise locking protrusions diametrically opposite and facing inward 2214, 2216 which, when locking sleeve 2210 is in a position, are received in an engaging manner within the corresponding portions of the notch. drive 2126 in the portion of the intermediate firing drive shaft 2120 and, when in another position, are not received within the drive slot 2126 to thereby allow relative axial movement between locking sleeve 2210 and the intermediate firing drive shaft 2120.

[0135] Now with reference to Figures 8 and 12 to 14, in the illustrated example, the 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 proximal articulation actuator 1310. This arrangement allows locking sleeve 2210 to rotate slightly in and out of the engagement with the intermediate firing drive shaft portion 2120 While remaining in engagement with the notch 1319 in the proximal articulation driver 1310. For example, when the locking sleeve 2210 is in its engaged position, the locking protrusions 2214, 2216 are positioned inside a driving notch 2126 in the portion of the intermediate firing drive shaft 2120, so that a force 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 movement proximal thrust u is then transmitted from the locking sleeve 2210 to the proximal pivoting actuator 1310 in order to articulate the surgical end actuator 1500. In effect, the trigger member assembly 2110, the locking sleeve 2210 and the proximal pivot actuator 1310 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 elements 2214, 2216 may not be received inside the drive notch 2126 in the portion of the intermediate firing 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 hinge drive 1310).

[0136] In the illustrated example, the relative movement of the lock sleeve 2210 between its engaged and disengaged positions can be controlled by a 2200 gear assembly that interfaces with the 1910 proximal closing tube of the 1900 proximal closing set. More specifically and with reference to Figures 8 and 9, the 2200 gear set additionally includes a 2240 gear wrench that is configured to be slidably received within a 2217 key groove formed on the outer perimeter of the locking sleeve 2210. This arrangement allows the 2240 shift wrench to move axially with respect to the 2210 locking sleeve. Referring to Figures 8 to 11, the 2240 shift wrench includes a 2242 actuating pin that extends through a cam or cam opening 1926 in the proximal closing tube portion 1920. See Figure 9. A cam surface 2243 is also provided adjacent the actuator pin 2242 which is configured to interact with the cam opening 1926 in order to cause the shift switch 2240 to rotate in response to the axial movement of the proximal closing tube portion 1920.

[0137] Also in the illustrated example, the gear unit 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 torsion spring of the switching cylinder 2226 (Figures 12 to 14) is mounted on the switching cylinder 2220 and attaches to the nozzle portion 1244 to apply a torsional bias or rotation (arrow SR in Figures 10 and 11) that serves to rotate the switching cylinder 2220 until the actuator pin 2242 reaches the end of the arcuate screw segment 2224. See Figures 11 and 12. When in this position, the switch cylinder 2220 can provide a torsional propensity to the 2240 gear switch that , in this way, causes locking sleeve 2210 to rotate in its engaged position with the intermediate firing drive shaft portion 2120. This position also corresponds to the unacted configuration of the 1900 proximal closing assembly. In one arrangement, for example, when the proximal closing assembly 1900 is in an unactivated configuration (the anvil 1810 is in an open position spaced away from the 1700 surgical clamp / clamp cartridge), the 2242 actuator pin is located in the upper portion of the cam opening 1926 at the proximal closing tube portion 1920. When in this position, the 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 actuator surgical end 1500 to a desired orientation, the user can then trigger the 1900 proximal closure set. The action of the 1900 proximal closure set will result in n the distal displacement of the proximal closing tube portion 1920 to finally apply a closing motion to the anvil 1810. This distal displacement of the proximal closing tube portion 1920 will result in the opening of the cam 1926 in order to interact with the surface of cam 2243 on the actuator pin 2242 to thereby make the shift key 2240 turn the locking 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 articulation drive 1310. Further details regarding the operation of the switch cylinder cylinder 2220 and lock sleeve 2210, as well as articulation arrangements

alternative triggering and triggering devices that can be used with the various sets of interchangeable surgical tools described here, can be found in US Patent Application Serial No. 13 / 803,086, currently Patent Application Publication Serial No. 2014 / 0263541, and patent application serial number 15 / 019.196, the disclosures of which are hereby incorporated by reference in the present invention.

[0138] With reference again to Figures 8 to 13, the switching cylinder 2220 may additionally comprise openings at least partially circumferential 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 switch cylinder 2220 and nozzle assembly 1240. The nozzle pins 1245 extend through corresponding openings 1923 in the proximal closing tube portion 1920 to be seated on the pin fittings 1254 on the central column assembly 1250. See Figures 8 and 9. This arrangement allows the user to rotate the central column assembly 1250 around the geometric axis of the drive shaft by rotating the nozzle assembly

1240.

[0139] Also as shown in Figures 7 and 12 to 14, the interchangeable tool set 1000 can comprise a set of the slip ring 1230 that can be configured to supply electrical energy to and / or the actuator of surgical end 1500 and / or transmit signals to and / or from surgical end actuator 1500, back to a microprocessor 560 (Figure 2) in the handle set 500 or in the robotic system controller, for example. More details about the 1230 slip ring assembly and associated connectors can be found in US patent order Serial No. 13 / 803.086, currently Order Order Publication

US Patent No. 2014/0263541 and US Patent Application Serial No. 15 / 019,196, each of which has been incorporated by reference in its entirety as well as in US Patent Application Serial No. 13 / 800,067 entitled STAPLE CARTRIDGE TISSUE THI-CKNESS SENSOR SYSTEM, currently Publication of Patent Application USP 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 that have been incorporated by reference, the interchangeable surgical tool set 1000 can also comprise at least one sensor that is configured to detect the position of the switching 2220.

[0140] Again with reference to Figure 2, the chassis of the tool 1210 includes at least one, and preferably two, tapered fastening portions 1212 formed therein, which are adapted to be received inside the slot slots corresponding 507 formed within the distal end portion of the handle structure 506 of the handle set 500. Various sets of interchangeable surgical tools employ a locking system 1220 to removably couple the set of interchangeable surgical tools 1000 to the handle structure 506 of the handle assembly 500. As can be seen in Figure 7, for example, in at least one form, the locking system 1220 includes a locking member or locking fork 1222 which is movably coupled to the tool chassis 1210. In the illustrated embodiment, for example, the locking fork 1222 has a U-shape with two spaced legs extending downwards 1223 The legs 1223 each have a pivot pin (not shown) formed in the legs, which are adapted to be received in corresponding holes formed in the chassis of the tool 1210. This arrangement facilitates the pivoting fixation of the locking fork 1222 to the tool chassis 1210. The locking fork 1222 may include two locking pins projecting proximally 1224 that are configured to release reliably to the holders or corresponding locking grooves 509 at the distal end of the grip structure 506 of the grip set 500. See Figure 2. In several ways, the locking fork 1222 is forced in the proximal direction by a spring or bias member 1225. The locking fork 1222 can be actuated by a locking button 1226 which is slidably mounted on a set of lock actuator 1221 which is mounted on the tool frame 1210. The locking button 1226 can be forced in one direction proximal to the locking fork 1222. The locking fork 1222 can be moved to an unlocked position with the locking button 1226 in the distal direction, which also causes the locking fork 1222 to rotate out of the retaining latch with the distal end of the holding frame 506. When the locking fork 1222 is in "holding latch" with the distal end of the holding frame 506, the locking pins 1224 are seated with retention - tion inside the corresponding holders or locking grooves 509 at the distal end of the 506 grip structure.

[0141] In the illustrated arrangement, the locking fork 1222 includes at least one and, preferably, two locking hooks 1227 which are adapted to come into contact with the corresponding locking pin portions 1943 which are formed movable member of 1940 closing. When the 1940 closing movable member is in a non-actuated position, 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, locking hooks 1227 do not come into contact with the locking pin portions 1943 on the closing movable member 1940. However, when the closing movable member 1940 is moved to an actuated position, the locking fork 1222 is prevented from being articulated to an unlocked position. In other words, if the doctor tried to articulate 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 the same gi - distally, locking hooks 1227 on locking fork 1222 would come into contact with the portions of locking tab 1943 on the reciprocating closing element 1940 and prevent movement of the locking fork 1222 to an unlocked position.

[0142] Referring again to Figure 6, the cutter bar 2130 may comprise a laminated beam structure that includes at least two layers of strip. Such bundle layers may comprise, for example, stainless steel bands that are interconnected, for example, by welding or fixing joints at their proximal ends and / or at other locations along their length. In alternative embodiments, the distal ends of the bands are not connected to allow the laminates or bands to spread out in relation to each other when the end actuator is pivoted. Such an arrangement allows the cutter bar 2130 to be sufficiently flexible to accommodate the end actuator joint. Several laminated cutter bar provisions are presented in US Patent Application Serial No. 15 / 019,245, entitled SURGICAL INSTRUMENTS WITH CLOSURE STROKE REDUCTION ARRANGEMENTS, which is incorporated by reference in its entirety. As can also be seen in Figure 6, a set of firing drive shaft support 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 operation of the firing drive shaft 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 no US Patent Application Serial No. 15 / 019,220, entitled SURGICAL INSTRUMENT WITH ARTICULATING AND AXI-ALLY TRANSLATABLE END EFFECTOR, which are hereby incorporated by reference in their respective totalities.

[0143] 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 cutting portion of fabric 2144. The body portion 2142? protrudes through an elongated slot 1604 in the elongated channel 1602 and ends at a base member 2146 that extends laterally on either side of the body portion 2142. As the firing member 2140 is driven distally through the surgical clamps / clamps 1700, the base member 2146 moves within a passage 1622 (Figure 48) in the elongated channel 1602 which is located under the clamp / clamp cartridge 1700. In one arrangement, the body portion 2142 includes two lateral flaps that project laterally 2145 that can move above the central passage inside the 1700 surgical staple / clamp cartridge. See Figure 6. The tissue cutting portion 2144 is arranged between a portion of top tip projecting distally 2143. As can be seen further in Figure 6, firing member 2140 may additionally include two top flaps, pins or anvil hitch 2147 that extend late usually. 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. In an arrangement, to facilitate the mounting of the anvil 1810 and the firing element 2140, the top of the anvil body 1812 has an opening 1817 therein. 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 attached to the anvil body 1812 by welding or other suitable fixation means. .

[0144] Again with reference to Figure 6, the firing 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 inside the staple cartridge body / surgical fasteners 1702 from a proximal starting position adjacent to the proximal end 1704 of the cartridge body 1702 to a final position adjacent to the distal end 1706 of the cartridge body 1702. The cartridge 1702 operationally supports a plurality of clip drivers (not shown) which are aligned in rows on each side of a centrally arranged slot 1708. Centrally arranged slot 1708 allows the firing member 2140 to pass through it and cut the tissue that is stuck between the anvil 1810 and the staple cartridge 1700. The actuators are so associated with matching staple / fastener pockets 1712 that open across the upper platform surface 1710 of the cartridge body

1702. Each of the clamp actuators holds one or more clamps / surgical clamps or clamps (not shown) on them. 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.

[0145] The attachment of the interchangeable surgical tool set 1000 to the handle set 500 will now be described with reference to Figure 2. To start the coupling process, the doctor can position the tool frame 1210 of the interchangeable surgical tool set 1000 above or adjacent to the distal end of the grip structure 506 so that the tapered clamping 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 a geometry axis IA installation which is perpendicular to the geometry axis of the drive axis SA to hold the tapered clamping portions 1212 in "operational engagement" with the recessed receiver slots 507 at the distal end of the 506 grip structure. When doing this, the firing pin 2128 in the portion on the intermediate firing drive shaft 2120 will also be seated on the fixing base 542 (not shown) on the longitudinally movable driving member (not shown) on the grip set 500 and the fixing pin portions 516 on the closing link 514 will be seated on the corresponding hooks 1942 on the reciprocating closing element 1940. As used in the present invention, the term "operable hitch" in reference to two components means that the two components are engaged with each other in such a way that, by applying a movement of actuation to them, the components can perform the desired action, function and / or procedure.

[0146] During a typical surgical procedure, the doctor may inform

bring the surgical end actuator 1500 to the surgical site through a trocar or other opening in the patient to access the target tissue.

In doing so, the physician typically axially aligns the surgical end actuator 1500 along the geometric axis of the drive axis (non-articulated state). Once the surgical end actuator 1500 passes through the trocar port, for example, the physician may need to articulate the end actuator 1500 to position it advantageously adjacent to the target tissue.

This occurs before closing the anvil on the target tissue, so that the closing trigger system 510 would remain unactivated.

When in this position, the actuation of the triggering system 530 will result in the application of articulation movements to the proximal articulation driver 1310. Once the end actuator has reached the desired articulated position, the triggering system 530 is deactivated and hinge lock 1400 can hold the surgical end actuator 1500 in the hinged position.

The doctor can then activate the closing drive system 510 to close the cuff 1810 on the target tissue.

Such actuation of the closing drive system 510 may also result in the decoupling of the gear set 2200 from the proximal articulation driver from the portion of the intermediate firing drive shaft 2120. Thus, once the target tissue has been captured in the actuator of surgical end 1500, the physician can again activate the trigger drive system 530 to axially advance the trigger member 2140 through the staple cartridge / surgical fasteners 1700 to cut the trapped tissue and fire the staples into the tissue cutting.

Other closing and firing drive arrangements, actuator arrangements (both portable and hand or manual, automated or robotic) can also be used to control the axial movement of the closing system components, the components of the articulation system and / or the components of the firing system components of the surgical tool set 1000 without departing from the spirit and scope of the various inventions presented in the present invention.

[0147] Again with reference to Figure 1, the surgical system 10 illustrated in that Figure includes four sets of interchangeable surgical tools 1000, 3000, 5000 and 7000 that can each be effectively used with the same handle set 500 for perform different surgical procedures. Turning now to Figures 16 to 18, the interchangeable surgical tool set 3000 includes a 3500 surgical end actuator comprising a first 3600 jaw and a second 3800 jaw. In one arrangement, the first jaw it comprises an elongated 3602 channel that is configured to operationally support a 3700 surgical staple / fastener cartridge inside. The second claw 3800 comprises an anvil 3810 that is pivotally supported in relation to the elongated channel 3602. The interchangeable surgical tool set 3000 includes a hinge system 3300 that comprises a hinge joint 3302 and a hinge lock 3400 which can be configured to release the 3500 surgical end actuator in a desired articulated position relative to a geometric axis of the drive shaft SA. Details regarding the construction and operation of the 3400 joint lock, as well as alternative locking configurations and operational details, 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, the description of which is incorporated herein, by reference, in its entirety. Additional details related to the 3400 toggle lock can also be found in US Patent Application Serial No. 15 / 019,196, filed on February 9, 2016, entitled "SURGICAL INSTRUMENT ARTICULATION MECHANISM WITH SLOTTED SECONDARY CONSTRAINT", the description of which is incorporated herein by way of reference, in its entirety.

[0148] As can be seen in Figure 17, the interchangeable surgical tool set 3000 includes a 3200 tool frame assembly comprising a 3210 tool chassis that operationally supports a 3240 nozzle assembly therein. In one form, the nozzle assembly 3240 comprises nozzle portions 3242, 3244, as well as a wheel portion of the actuator 3246 that is configured to be coupled to the portions of the assembled nozzle 3242, 3244 by pressure fittings, pins, screws , etc. The interchangeable surgical tool set 3000 includes a 3900 proximal closure set that is operationally coupled to a distal closing set 4000 that is used to close and / or open the anvil 3810 of the 3500 surgical end actuator, as will be discussed further in more detail below. In addition, the interchangeable surgical tool set 3000 includes a 3250 "elastic" back set that operationally supports the 3900 proximal closure set and is coupled to the 3500 surgical end actuator. An exemplary shape of the 3250 center column set is revealed in US Patent Application Serial No. 15 / 385,911, entitled SURGICAL STAPLE / FASTENERS WITH INDEPENDENTLY ACTUATABLE CLOING AND FIRING SYSTEMS, the description of which is hereby incorporated by reference in the present invention. For example, the back assembly 3250 may comprise an elastic back member that has a proximal end portion 3253 and a distal end portion 3280 that is separate from the proximal end portion

3253 of the elastic back assembly 3250 by a stretching feature 3282 formed between them. In addition, a stretch-limiting insert 3284 is supported with retention between the distal end portion 3280 and the proximal end portion 3253. In various arrangements, the elastic center column assembly 3250 can be manufactured from, for example , suitable polymeric material, rubber, etc. which has a modulus of elasticity designated as ME, for reference purposes. The extension limiter 3284 may have an elasticity module designated as ME> 2 for reference purposes. In various circumstances, the 3284 stretch limiter insert also includes a pair of 3285 stretch limiters (only one is shown in Figure 17). Stretch limiter 3285 can have an elastic modulus for reference purposes of ME3. In at least one provision, ME3 <ME2 <ME. More details on at least one implementation of the elastic back 3232 and the stretch limiter 3284 insert can be found in US Patent Application Serial No. 15 / 385,911.

[0149] In the illustrated arrangement, the distal end portion 3280 of the dorsal assembly 3250 has an opening 3281 inside it to facilitate assembly. A central column cover 3283 can be attached to it to cover opening 3281 after the various components are mounted inside it. In the assembled state, the proximal end portion 3253 of the back assembly 3250 is pivotally supported on the 3210 tool chassis. In one arrangement, for example, the proximal end of the proximal end portion 3253 of the column set The central 3250 is fixed to a dorsal bearing (not shown) that is configured to be supported within the chassis of the 3210 tool. This arrangement facilitates the swiveling attachment of the 3250 back assembly to the 3210 tool chassis, so that the dorsal set

7T4 / 217 3250 can be selectively rotated around a geometric axis of the drive axis SA? in relation to the tool chassis 3210. In particular, in an arrangement, for example, the proximal end portion 3253 of the back assembly 3250 includes two diametrically opposed pin fittings 3254 (only one can be seen in Figure 17) that are individually configured to receive a corresponding nozzle pin (not shown) that extends inwardly from each of the 3242, 3244 nozzle portions. This arrangement facilitates the rotation of the 3250 center column assembly around the geometry axis - traction of the drive shaft SA, by rotating the wheel portion of the actuator 3246 of the nozzle assembly 3240.

[0150] Now with reference to Figure 18, the distal end portion 3280 of the elastic back assembly 3250 is attached to a segment of distal structure 3286 that operationally supports the articulation lock 3400 therein. The back assembly 3250 is configured to, firstly, slide a set of the firing member 4110 slidingly inside and, secondly, to support the proximal closing tube 3910 that extends around it of the back assembly 3250. The central column assembly 3250 can also be configured to slide a proximal articulation actuator 3310 slidingly. As can be seen in Figure 18, the distal frame segment 3286 is pivotally coupled relative to the elongated channel 3602 by an end actuator assembly set 3290. In one arrangement, for example, the distal end 1562 of the distal frame segment 3286 has a pivot pin 3288 formed therein. The pivot pin 3288 is adapted to be pivotally received within a pivot hole 3292 formed in the pivot base portion 3291 of the end actuator mounting set 3290. The end actuator mounting set 3290 is fixed to a proximal end 3610 of the elongated channel 3602 by means of a spring pin 3620 or another suitable member which is received into the mounting holes 3611 in the proximal end portion 3610. The pivot pin 3288 defines a pivot geometry axis AA, which is transversal to the geometric axis of the drive axis SA '. See Figure 18. This arrangement facilitates the pivoting displacement (that is, the articulation) of the 3500 surgical end actuator around the AA geometric axis, articulating in relation to the elastic back 3232. The distal 3286 segment is additionally configured to support the 3400 hinge lock inside. Various articulation lock arrangements can be used. At least one form of joint lock 3400 is described in more detail in US Patent Application Serial No. 13 / 803,086, entitled "ARTICUL-

TABLE SURGICAL INSTRUMENT COMPRISING AN ARTICULATION LOCK ", currently US Patent Application Publication No. 2014/0263541, the description of which is incorporated herein by reference in its entirety. Additional details relating to the joint lock can also be found in the US Patent Application Serial No. 15 / 019,196, filed on February 9, 2016, entitled SURGI-

CAL INSTRUMENT ARTICULATION MECHANISM WITH SLOTTED SECONDARY CONSTRAINT.

[0151] In the illustrated example, the 3500 surgical end actuator is selectively pivotable around the geometric hinge axis AA, by the hinge system 3300. In one form, the hinge system 3300 includes the 3310 proximal hinge actuator makes operational interface with the 3400 articulation lock. The 3400 articulation lock includes a 3402 articulation structure that is adapted to operationally engage a 3293 drive pin in the pivot base portion 3291 of the end actuator assembly set 3290. In addition, a cross link 3294 can be connected to the drive pin 3293 and the articulation structure 3402 to assist the articulation of the 3500 surgical end actuator. As indicated above, additional details related to the operation of the articulation lock 3400 and the articulation structure 3402 can be found in US Patent Application Serial No. 13 / 803,086, now US Patent Application Publication No. 2014/0263541. More details on the end actuator assembly set and the 3294 cross link can be found in US Patent Application Serial No. 15 / 019,245, filed February 9, 2016, entitled SURGI-CAL INSTRUMENTS WITH CLOSURE STROKE REDUCTION AR- RANGEMENTS, whose description is incorporated herein, by reference, in its entirety. As further described here, as well as in other disclosures incorporated herein by reference in the present invention, the axial movement of the proximal articulation actuator 3310 will result in the engagement / disengagement of the 3400 articulation lock to thus apply articulation movements to the elongated channel. 3602 and thus cause the 3500 surgical end actuator to hinge around the AA hinge axis? in relation to the 3250 central column assembly.

[0152] The anvil 3810 in the illustrated example includes an anvil body 3812 that ends at the anvil mounting portion 3820. The anvil mounting portion 3820 is movably or articulated supported on the elongated channel 3602 for selective pivoting displacement in relation to it around a fixed pivot pivot geometric axis PA> (FIGURE 18) that is transversal to the geometric axis of the drive axis SA ». In the illustrated arrangement, a rotating pin of the anvil 3822 extends laterally away from each side of the anvil mounting portion 3820 to be received on a corresponding rotating pin base 3613 formed on the vertical walls 3612 of the proximal end portion 3610 of the elongated channel

3602. The movement of the 3810 anvil in relation to the elongated channel

3602 is effected by the axial movement of the 3900 proximal closing system assembly and the distal closing system assembly

4000. In the illustrated arrangement, the proximal closing assembly 3900 comprises a proximal closing tube 3910 that has a proximal end 3912 and a distal end 3914. The proximal end is swiveled in a reciprocating closing element 3940 which is slidably supported within the 3210 tool chassis, so that it can move axially with respect to it. In one form, the reciprocating locking element 3940 includes a pair of hooks that project proximally 3942 that are configured for fixing to the transverse fixing pin 516 which is attached to the closing hinge assembly 514 of the handle assembly 500 The proximal end 3912 is coupled to the reciprocating closing element 3940 for rotation with respect to it. For example, a U-shaped connector 3944 is inserted into an annular slot 3916 in the proximal portion 3912 and is retained within the vertical slots 3946 in the reciprocating closing member 3940. This arrangement serves to secure the proximal closing member 3900 to the reciprocating element closing mechanism 3940 for axial displacement with the same, while allowing the proximal closing tube 3910 to rotate in relation to the reciprocating closing element 3940 around the geometric axis of the drive shaft SA> 2. As discussed above in connection with the interchangeable surgical tool set 1000, a closing spring (not shown) can extend over the proximal end 3912 of the proximal closing tube 3910 to prop the reciprocating closing element 3940 in the proximal direction PD which can serve to articulate the closing trigger 512 in the handle set 500 (Figure 2) in the unacted position when the interchangeable surgical tool set 3000 is operationally coupled to the handle set 500 in the manner described above.

[0153] As can be seen in Figure 18, the distal end 3914 of the proximal closing tube 3910 is attached to the distal closing set 4000. The distal end 3914 includes the upper and lower lugs 3917, 3918 that are configured to be movably coupled to a closing sleeve of the end actuator or segment of the distal closing tube 4030. The segment of the distal closing tube 4030 includes an upper lock 4032 and a lower lock that protrude proximally from one end near it. An upper double pivot link 4060 pivotally attaches to the upper latches 3917 and 4032 and a lower double pivot link 4064 pivotally attaches to the lower latches 3918 and 4034 together as described above. The distal advance of the distal closing tube segment 4030 in the anvil mounting portion 3820 will result in the anvil 3810 closing or pivoting displacement towards the elongated channel 3602 around the geometric axis of the fixed pivot PA2. In the illustrated arrangement, the distal closing tube segment 4030 also includes positive opening 4040 features of the claw or anvil that are configured to co-act with ramp surfaces or portions on the anvil mounting portion 3820 in order to that the anvil 3810 pivots from a closed position to an open position as the segment of the distal closing tube 4030 moves proximally back to an initial position. Other modalities may not use the positive jaw opening (PJO) features, but they may use springs or other propensity arrangements to prop the anvil to the open position when the pipe segment is closed. distal has been retracted to its most proximal initial position. More details on settings and the operation of the anvil opening features can be found, for example, in US Patent Application Serial No. 15 / 385,911, entitled SURGICAL STAPLE / FASTENERS WITH IN- DEPENDENTLY ACTUATABLE CLOSING AND FIRING SYSTEMS.

[0154] In the illustrated arrangement, the interchangeable surgical tool set 3000 additionally includes a trigger system generally referred to as 4100. In several examples, the 4100 trigger system includes a 4110 trigger member set that is supported for displacement axial within the central column assembly 3250. In the illustrated embodiment, the trigger member 4110 assembly includes a portion of the intermediate trigger drive shaft 4120 that is configured to connect to a distal cutting portion or 4130 cutting bar. support cushion arrangement 4121 can be employed to support the intermediate firing drive shaft portion 4120 within the center column assembly 3250. The firing member assembly 4110 can also be called in the present invention a "second drive shaft" and / or a "second drive shaft assembly". As can be seen in Figure 18, the intermediate firing drive shaft portion 4120 may include a longitudinal slot 4124 at a distal end 4122 thereof, which can be configured to receive a proximal end 4132 of the cutter bar 4130. The slot longitudinal end 4124 and the proximal end 4132 of the cutter bar 4130 can be dimensioned and configured to allow relative movement between them and may comprise a sliding joint 4134. The sliding joint 4134 can allow the firing drive shaft portion intermediate 4120 of the firing member assembly 4110 is moved to articulate end actuator 3500 without moving, or at least substantially moving, the cutter bar 4130, as discussed above. In the illustrated arrangement, a proximal end 4127 of the intermediate firing drive shaft portion 4120 has a firing pin for the firing drive shaft 4128 formed on it that is configured to be seated on the coupling base (no shown) that is over the distal end of the longitudinally movable drive member (not shown) of the trigger drive system 530 within the cable assembly 500, as discussed above. This arrangement facilitates axial movement of the 4120 intermediate drive shaft portion by actuating the 530 trigger drive system. Other mounting configurations can also be used to couple the drive shaft portion of the drive intermediate stop 4120 to other triggering arrangements (for example, manual, robotic, etc.).

[0155] In addition to the above, the interchangeable tool set 3000 can include a 4200 gear set, which can be configured to selectively and releasably couple the proximal articulation driver 3310 to the 4110 as described above. In one form, gear unit 4200 comprises a locking ring or locking sleeve 4210 positioned around the intermediate firing drive shaft portion 4120 of firing member 4110, where locking sleeve 4210 can be rotated between an engaged position in which the locking sleeve 4210 engages the proximal articulation driver 3310 to the trigger member 4110 and a disengaged position, where the proximal articulation driver 3310 is not operably coupled to the trigger member assembly 4110. As discussed above, the intermediate firing drive shaft 4120 portion of firing member assembly 4110 is formed with a driving groove 4126. Locking sleeve 4210 comprises a cylindrical body, or at least substantially cylindrical, which includes a longitudinal opening 4212 which is configured to receive the portion of the intermediate firing drive shaft 4120 therethrough. The locking sleeve 4210 can comprise locking protrusions diametrically opposite and facing inwards 4214, 4216 which, when the locking sleeve 4210 is in a position, are received in an engaging manner within the corresponding portions of the drive notch 4126 in the axis portion 4120 intermediate firing drive and, when in another position, are not received within the driving notch 4126 to thereby allow relative axial movement between the locking sleeve 4210 and the intermediate firing drive shaft portion 4120, as discussed in more detail above. The locking sleeve 4210 additionally includes a locking member 4218 that is sized to be movably received within a notch 3319 at a proximal end of the 3310 proximal pivoting actuator. When the locking sleeve 4210 is in its engaged position, the locking protrusions 4214, 4216 are positioned within a drive notch 4126 defined in the middle portion of the trigger drive shaft 4120, so that a distal pushing force and / or a proximal pulling force can be transmitted from the 4110 firing member assembly to the locking sleeve 4210. Such a pulling or proximal pushing motion is then transmitted from the locking sleeve 4210 to the nearby articulation driver 3310 in order to articulate the 3500 surgical end actuator.

[0156] As discussed above, in the illustrated example, the relative movement of the lock sleeve 4210 between its engaged and disengaged positions can be controlled by the exchange set 4200 which interfaces with the proximal closing tube 3910 of the set of proximal closure 3900. The exchange set 4200 additionally includes an exchange key 4240 that is configured to be received in a sliding way inside a key groove (similar to key groove 2217 illustrated in Figure 8) formed in the perimeter locking sleeve 4210. This arrangement allows the 4240 gear shift to move axially with respect to the 4210 lock gear. The operation of the 4200 gear set may be identical to the operation of the 2200 gear set which has been described in more detail above and will not be repeated again for the sake of brevity. More details, alternative arrangements and drive configurations that can be used are disclosed in other provisions that can be used and which are disclosed in US Patent Application No. 15 / 385,911, entitled SURGICAL STAPLE / FASTENERS WITH INDEPENDENTLY ACTUABLE CLOSING AND FIRING SYSTEMS, in US Patent Application Serial No. 13 / 803,086, now US Patent Application Publication No. 2014/0263541, and in US Patent Application Serial No. 15 / 019,196, as well as other disclosures that have been incorporated into this invention.

[0157] The interchangeable tool set 3000 may comprise a 3230 slip ring assembly that can be configured to conduct electrical energy to and / or the 3500 surgical end actuator and / or transmit signals to and / or from surgical end actuator 3500, back to a microprocessor 560 in the handle set 500 or robotic system controller, for example, as discussed above. More details on the 3230 slip ring assembly and associated connectors can be found in US patent application Serial No. 13 / 803.086, currently US Patent Application Publication No. 2014/0263541 and Paid Application. try US serial number 15 / 019,196, each of which has been incorporated by reference in its respective entirety as well as in US Patent Application serial number 13 / 800,067 entitled STAPLE CARTRIDGE TISSUE THICKNESS SENSOR SYSTEM, currently published Patent Application USP Patent Application US Serial No. 2014/0263552, which is hereby incorporated by reference in its entirety.

[0158] The interchangeable surgical tool set 3000 also employs a locking system 3220 to connect, for example, removably, the interchangeable surgical tool set 3000 to the handle structure 506 of the handle set 500. The lock 3220 can be identical to the lock system 1220 described in detail above. The cutter bar 4130 may comprise a laminated beam structure that includes at least two layers of beam. Such bundle layers may comprise, for example, stainless steel bands that are interconnected, for example, by welding or fixing joints at their proximal ends and / or at other locations along their length. In alternative modalities, the distal ends of the bands are not connected to allow the laminates or bands to spread in relation to each other when the end actuator is articulated. Such an arrangement allows the 4130 cutter bar to be flexible enough to accommodate the end actuator pivot. Several laminated cutter bar provisions are presented in US Patent Application Serial No. 15 / 019,245, entitled SURGICAL INSTRUMENTS WITH CLOUD SURE STROKE REDUCTION ARRANGEMENTS, which is incorporated by reference in its entirety. As can also be seen in Figure 18, a 4300 firing drive shaft support assembly is employed to provide lateral support to the 4130 cutter bar as it flexes to accommodate the 3500 surgical end actuator joint. for operating the 4300 firing axle support set and alternative cutter bar support arrangements can be found in US patent application No. 15 / 019.245, entitled SURGICAL INSTRUMENTS WITH CLOSURE STROKE REDUCTION ARRANGE - MENTS and in US Patent Application 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.

[0159] As can also be seen in Figure 18, a 4140 firing member or cutting member is attached to the distal end of the 4130 cutter bar. The 4140 firing member is configured to make operational interface with a 4150 slide assembly which is operationally supported inside the 3702 body of the 3700 surgical staples / fasteners cartridge. The 4150 slide assembly is slidably movable within the 3702 surgical staples / fasteners body from an initial position proximal adjacent the proximal end 3704 of the cartridge body 3702 to a final position adjacent to the distal end 3706 of the cartridge body 3702. The cartridge body 3702 operationally supports a plurality of clip drivers (not shown) which are aligned in rows on each side of a centrally arranged slot 3708. The centrally arranged slot 3708 allows firing member 4140 to pass through and cut the fabric that is stuck between the anvil 3810 and the staple cartridge 3700. The actuators are associated with corresponding staple pockets 37 12 that open across the 3710 platform surface of the 3702 cartridge body. Each of the staple actuators holds one or more surgical clips / fasteners or fasteners (not shown) on them. Slider assembly 4150 includes a plurality of inclined or wedge-shaped cams 4152 with each cam 4152 corresponding to a particular line of fasteners or drivers located on one side of slot 3708.

[0160] In an exemplary form, the firing member 4140 comprises a body portion 4142 that supports a knife or fabric cutting portion 4144. See Figure 49. Body portion 4142 projects through an elongated slit 3604 in the elongated channel 3602 and ends in a base member 4146 that extends laterally on each side of the body portion 4142. As the firing member 4140 is driven distally through the 3700 surgical clip / clamp cartridge, the base member 4146 moves within a passage 3622 in the elongated channel 3602 which is located under the surgical staple / clamp cartridge 3700. The tissue cutting portion 4144 is arranged between a top tip portion that projects distally 4143. As can be seen further in Figure 18, firing member 4140 may additionally include two top flaps, pins or anvil engaging features 4147 that extend laterally. As the firing member 4140 is driven distally, a top portion of the body portion 4142 extends through an anvil slot 3814 centrally arranged and the anvil engaging features 4147 slide over the corresponding projections 3816 formed on each side of the slot anvil

3814. More details on the 4140 firing member, the 4150 slide assembly and its various alternatives, as well as examples of their operation, will be discussed in more detail below, and can also be found in US Patent Application no. series15 / 385.911, entitled SURGICAL STAPLE / FASTENERS WITH INDEPENDENTLY ACTUABLE TABLE CLOSING AND FIRING SYSTEMS. The interchangeable surgical tool set 3000 can be for the handle set 500 in the manner described above in relation to the interchangeable surgical tool set 1000.

[0161] Again with reference to Figure 1, and as already discussed, the surgical system 10 illustrated in this Figure includes four sets of interchangeable surgical tools 1000, 3000, 5000 and 7000 that can each be effectively used with the same 500 handle set to perform different surgical procedures. Turning now to Figures 19 to 21, the interchangeable surgical tool set 5000 includes a 5500 surgical end actuator comprising a first 5600 jaw and a second 5800 jaw. In one arrangement, the first jaw comprises an elongated channel 5602 that is configured to operationally support a 5700 surgical staple / clamp cartridge inside. The second claw comprises an anvil 5810 which is movably supported in relation to the elongated channel 5602. The interchangeable surgical tool set 5000 includes a hinge system 5300 comprising a hinge joint 5302 and a hinge lock 5400 which can be configured to release the 5500 surgical end actuator in a desired articulated position relative to a geometric axis of the SAsz drive axis. Details regarding the construction and operation of the 5400 joint lock, as well as alternative locking configurations and operational details, can be found in US Patent Application Serial No. 15 / 385,894, entitled SHAFT ASSEMBLY COMPRISING A LOCK OUT, the full description of which is here incorporated, as a reference, in its entirety. Alternative joint locking arrangements can also be found in US Patent Application Serial No. 13 / 803,086, entitled ARTICULATABLE SURGICAL INSTRUENT COMPRISING AN ARTICULATION LOCK, currently US Patent Application Publication No. 2014/0263541, and patent application serial number 15 / 019,196, filed on February 9, 2016, entitled

SURGICAL INSTRUMENT ARTICULATION MECHANISM WITH SLOTTED SECONDARY CONSTRAINT, all the disclosures of each of these references being incorporated herein by reference.

[0162] As can be seen in Figure 20, the interchangeable surgical tool set 5000 includes a tool frame set 5200 comprising a 5210 tool chassis that operationally supports a 5240 nozzle assembly therein. In one form, the nozzle assembly 5240 comprises nozzle portions 5242, 5244, as well as a wheel portion of the actuator 5246 which is configured to be coupled to the portions of the assembled nozzle 5242, 5244 by pressure fittings, pins, screws , etc.

The interchangeable surgical tool set 5000 includes a 5900 proximal closure set that is operationally coupled to a distal closing set 6000 that is used to close and / or open the anvil 5810 of the 5500 surgical end actuator, as will be discussed further in more detail below.

In addition, the interchangeable surgical tool set 5000 includes a 5250 central column set that operationally supports the 5900 close closure set and is coupled to the 5500 surgical end actuator. In the illustrated arrangement, the column set central 5250 includes a distal end portion 5280 that has an opening 5281 inside to facilitate assembly.

A central column cover 5283 can be attached to it to cover opening 5281 after the various components are mounted inside it.

In the assembled state, a proximal end portion 5253 of the 5250 back assembly is pivoted to the 5210 tool chassis. In a layout, for example, the proximal end of the proximal end portion 5253 of the assembly 5250 torso bearing is attached to a dorsal bearing (not shown) that is configured to be supported within the 5210 tool chassis. This arrangement facilitates the rotating attachment of the 5250 dorsal assembly to the 5210 tool chassis, so that the 5250 dorsal assembly can be selectively rotated around a geometric axis of the drive axis SA; in relation to the 5210 tool chassis. In particular, in an arrangement, for example, the proximal end portion 5253 of the 5250 back assembly includes two diametrically opposed pin fittings 5254 (only one can be seen in Figure 20) that are individually configured to receive a corresponding nozzle pin (not shown) extending inwardly from each of the nozzle portions 5242, 5244. This arrangement facilitates the rotation of the 5250 center column assembly around the axis geometric axis drive system; by rotating the wheel portion of actuator 5246 of the 5240 nozzle assembly.

[0163] Now with reference to Figure 21, the distal end portion 5280 of the back assembly 5250 is fixed to a segment of distal structure 5286 that operationally supports the joint lock 5400 therein. The 5250 back assembly is configured to first slide a set of the firing member 6110 slidingly inside and secondly to support a 5910 proximal closing tube that extends around the 5250 back assembly. The 5250 center post assembly can also be configured to slide a first 5310 pivot driver and a second 5320 joint driver. As can be seen in Figure 21, the distal structure 5286 is pivotally coupled to the proximal end 5610 of the elongated channel 5602. In one arrangement, for example, the distal end 1562 of the distal structure segment 5286 has a pivot pin 5288 formed therein. Pivot pin 5288 is adapted to be pivotally received within a pivot hole 5611 formed in the proximal end portion 5610 of the elongated channel 5602. Pivot pin 5288 defines a geometric axis of articulation AA; 3 which is transversal to the geometric axis of the drive axis SA ;. See Figure 21. This arrangement facilitates the pivoting displacement (that is, the articulation) of the 5500 surgical end actuator around the AA geometric axis; articulation in relation to the central column assembly

5250. The distal frame segment 5286 is additionally configured to support the hinge lock 5400 inside.

[0164] In the illustrated arrangement, a distal end 5314 of the first hinge driver 5310 is formed with a link 5316 which is adapted to receive a first hinge pin 5618 therein, which is formed over the proximal end portion 5610 of the elongated channel 5602. Similarly, a distal end 5324 of the second hinge driver 5320 has a link 5326 that is adapted to receive a second hinge pin 5619 therein, which is formed over the proximal end portion 5610 of the channel elongated 5602. In one arrangement, for example, the first hinge drive 5310 additionally comprises a proximal rack of teeth 5315 which is engaged in engagement with an intermediate gear 5330 pivotally supported on the central column assembly

5250. Similarly, the second articulation drive 5320 additionally comprises a proximal rack of teeth 5325 that are engaged in engagement with the intermediate gear 5330. Thus, in such an arrangement, the movement of the first articulation drive 5310 in the direction distal DD will result in the movement of the second 5320 articulation trigger in the proximal direction PD. Moving the first 5310 hinge actuator in the proximal direction PD will result in the movement of the second 5320 hinge actuator in the distal direction DD. In this way, this movement of the first and second articulation actuators 5310, 5320 will simultaneously provide pushing and pulling movements to the surgical end actuator 5500 to articulate it around the geometric articulation axis AA :.

[0165] The anvil 5810 in the illustrated example includes an anvil body 5812 that ends at the anvil assembly portion 5820. The anvil assembly portion 5820 is movably supported over the elongated channel 5602 to perform the movement selective and vertical pivot in relation to it.

In the illustrated arrangement, an anvil rotating pin 5822 extends laterally away from each side of the anvil mounting portion 5820 to be received on a corresponding unrestricted vertical base 5613 formed on the vertical walls 5612 of the end portion. proximal 5610 of the elongated canal 5602. The movement of the anvil 5810 in relation to the elongated canal 5602 is effected by the axial movement of the proximal closing system assembly 5900 and the distal closing system assembly 6000. In the illustrated arrangement, the proximal closing assembly 5900 comprises the proximal closing tube 5910 which has a proximal end 5912 and a distal end 5914. The proximal end 5912 is pivotally supported on a reciprocating closing element 5940 which is slidably supported within the 5210 tool frame , so that it can move axially in relation to it.

In one form, the reciprocating closing element 5940 includes a pair of proximally projecting hooks 5942 that are configured for attachment to the cross fixation pin 516 which is attached to the closing hinge assembly 514 of the handle assembly 500. A proximal end 5912 of proximal closing tube 5910 is coupled to the reciprocating closing element 5940 for relative rotation with respect to it.

For example, a U-shaped connector 5944 is inserted into an annular slot 5916 in the proximal portion 5912 and is retained within the vertical slots 5946 in the reciprocating closing element 5940. This arrangement serves to secure the proximal closing member 5900 to the reciprocating closing element 5940 for axial displacement with the same, while allowing the 5910 proximal closing tube to rotate in relation to the reciprocating closing element 5940 around the geometric axis of the drive

SA3z. As discussed above in connection with the interchangeable surgical tool set 1000, a closing spring (not shown) can extend over the proximal end 5912 of the proximal closing tube 5910 to prop the reciprocating closing element 5940 in the proximal direction PD that can serve to articulate the closing trigger 512 in the handle set 500 (Figure 2) inside the unacted position when the interchangeable surgical tool set 5000 is operationally coupled to the handle set 500 in the manner described above.

[0166] As can be seen in Figure 21, the distal end 5914 of the proximal closing tube 5910 is attached to the distal closure set 6000. The distal end 5914 includes the upper and lower tabs 5917, 7918 that are configured to be movably coupled to a closing sleeve of the end actuator or segment of the distal closing tube 6030. The segment of the distal closing tube 6030 includes an upper lock 6032 and a lower lock that protrude proximally from one end near it. An upper double pivot link 6060 pivotally attaches to the upper latches 5917 and 6032 and a lower double pivot link 6064 pivotally attaches to the lower latches 5918 and 6034 together as described above. The segment of the distal closing tube 6030 includes an internal cam surface 6036 which is configured to engage with a cam an anvil cam surface 5821 on the anvil mounting portion 5820. The distal advance of the tube segment distal closure 6030 on the anvil mounting portion 5820 will result in the anvil 5810 closing or pivoting displacement towards the elongated channel 5602. In the illustrated arrangement, the vertical anvil flaps 5827 are formed on the 5820 anvil mounting portion and are configured to be contacted by two positive opening flap tabs 6038 that extend inwardly within the segment of the distal closing tube 6030. Each positive opening flap tab 6038 is configured to engage one of the corresponding anvil 5827 tabs to pivot anvil 5810 to an open position when the distal closing tube segment 6030 moves axially in the proximal direction PD.

[0167] In the illustrated arrangement, the interchangeable surgical tool set 5000 additionally includes a firing system generally referred to as 6100. In several examples, the firing system 6100 includes the firing member set 6110 that is supported for displacement axial within the 5250 center column assembly. In the illustrated mode, the firing member assembly 6110 includes an intermediate portion of the firing drive shaft 6120, which is configured to connect to a distal cutting portion or cutter bar 6130. The firing member assembly 6110 may 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 21, the intermediate firing drive shaft portion 6120 may include a longitudinal slot 6124 at a distal end 6122 thereof, which can be configured to receive a proximal end 6132 of the cutter bar 6130. The longitudinal slot 6124 and the proximal end 6132 of the cutter bar 6130 can be dimensioned and configured to allow relative movement between them and may comprise a sliding joint 6134. The sliding joint 6134 can allow the portion of the intermediate firing drive shaft 6120 of the firing member assembly 6110 is moved to pivot end actuator 5500 without moving, or at least substantially moving, the cutter bar 6130, as discussed above. In the illustrated arrangement, a proximal end 6127 of the intermediate firing drive shaft portion 6120 has a firing pin fixing shaft 6128 formed on it that is configured to be seated within a coupling base (no shown) which is over the distal end of the longitudinally movable drive member (not shown) of the trigger drive system 530 within the cable assembly 500, as discussed above. This arrangement facilitates the axial movement of the portion of the 6120 intermediate trigger drive shaft through the activation of the trigger drive system

530. Other clamping configurations can also be used to couple the portion of the intermediate trigger drive shaft to other trigger drive arrangements (for example, manual, robotic, etc.).

[0168] In addition to the above, the interchangeable tool set 5000 can include a gear set 6200, which can be configured to selectively and releasably couple the first hinge actuator 5310 to the firing member assembly 6110 as described above. In one form, the shift set 6200 comprises a locking ring or locking sleeve 6210 positioned around the intermediate firing drive shaft portion 6120 of the firing member assembly 6110, where locking sleeve 6210 can be rotated between an engaged position in which the locking sleeve 6210 couples the first hinge actuator 5310 to the firing member assembly 6110 and a disengaged position, where the first hinge actuator 5310 is not operably coupled to the firing member assembly 6110. As discussed above, the intermediate firing drive shaft portion 6120 of the firing member assembly 6110 is formed with a driving groove 6126. The locking sleeve 6210 comprises a cylindrical body, or at least substantially cylindrical, which includes a longitudinal opening that is configured to receive the portion of the intermediate firing drive shaft 6120 therethrough. Locking sleeve 6210 can comprise locking protrusions diametrically opposite and facing inward 6214, 6216 which, when locking sleeve 6210 is in a position, are received in an engaging manner within the corresponding portions of drive notch 6126 in the portion of the intermediate firing drive shaft 6120 and, when in another position, are not received within the drive notch 6126 to thereby allow relative axial movement between the locking sleeve 6210 and the shaft portion of the 6120 intermediate trigger drive, as discussed in more detail above. The locking sleeve 6210 additionally includes a locking member 6218 which is sized to be movably received within a notch 5319 at an end proximal to the first hinge actuator 5310. When the locking sleeve 6210 is in their engaged position, the locking protrusions 6214, 6216 are positioned inside a driving notch 6126 defined in the middle portion of the firing drive shaft 6120, so that a distal pushing force and / or a proximal pulling force can be transmitted from the firing member 6110 assembly to the locking sleeve 6210. Such a pulling or proximal pushing movement is then transmitted from the locking sleeve 6210 to the first hinge driver

5310. The axial movement of the first 5310 articulating actuator results in the axial movement of the second 5320 articulating actuator in an opposite direction to thus articulate the 5500 surgical end actuator.

[0169] As discussed above, in the illustrated example, the relative movement of the lock sleeve 6210 between its engaged and unfolded positions

can be controlled by the gear set 6200 that interfaces with the proximal closing tube 5910 of the proximal closing set 5900. The gear set 6200 additionally includes a 6240 gear switch that is configured to be received - slide groove within a key groove (similar to key groove 2217 shown in Figure 8) formed on the outer perimeter of locking sleeve 6210. Such an arrangement allows the 6240 gear shift to move axially with respect to locking sleeve 6210 The 6200 transmission set operation may be identical to the 2200 transmission set operation which has been described in more detail above and which will not be repeated again for the sake of brevity. More details, alternative arrangements and drive configurations that can be used are disclosed in other provisions that can be used and which are disclosed in US Patent Application No. 15 / 385,911, entitled SURGICAL STAPLE / FASTENERS WITH INDEPENDENTLY ACTUABLE CLOSING AND FIRING SYSTEMS, in US Patent Application Serial No. 13 / 803,086, now US Patent Application Publication No. 2014/0263541, and in US Patent Application Serial No. 15 / 019,196, as well as other disclosures that have been incorporated into present invention.

[0170] The interchangeable tool set 5000 can comprise a 5230 slip ring assembly that can be configured to conduct electrical energy to and / or the surgical end actuator 5500 and / or transmit signals to and / or from surgical end actuator 5500, back to a microprocessor 560 in the handle set 500 or robotic system controller, for example, as discussed above. More details on the 5230 slip ring assembly and associated connectors can be found in US patent application Serial No. 13 / 803,086, currently US Patent Application Publication No. 2014/0263541 and Paid Application. try US Serial No. 15 / 019,196, each of which has been incorporated by reference in its respective entirety as well as in US Patent Application Serial No. 13 / 800,067 entitled STAPLE CARTRIDGE TISSUE THICKNESS SENSOR SYSTEM, currently US Patent Application Publication Serial No. 2014/0263552, which is hereby incorporated by reference in its entirety.

[0171] The interchangeable surgical tool set 5000 also employs a 5220 locking system to connect, for example, removably, the interchangeable surgical tool set 5000 to the handle structure 506 of the handle set 500. The 5220 lock can be identical to the 1220 lock system described in detail above. The cutter bar 6130 may comprise a laminated beam structure that includes at least two layers of beam. Such bundle layers may comprise, for example, stainless steel bands that are interconnected, for example, by welding or fixing joints at their proximal ends and / or at other locations along their length. In alternative modalities, the distal ends of the bands are not connected to allow the laminates or bands to spread in relation to each other when the end actuator is articulated. Such an arrangement allows the cutter bar 6130 to be flexible enough to accommodate the end actuator hinge. Several laminated cutter bar provisions are presented in US Patent Application Serial No. 15 / 019,245, entitled SURGICAL INSTRUMENTS WITH CLOUD SURE STROKE REDUCTION ARRANGEMENTS, which is incorporated by reference in its entirety. As can also be seen in Figure 21, a 6300 firing drive shaft support assembly is employed to provide lateral support to the 6130 cutter bar as it flexes to accommodate the 5500 surgical end actuator joint. operation of the 6300 firing drive shaft support set and alternative cutter bar support arrangements can be found in US Patent Application No. 15 / 019.245, entitled SURGICAL INSTRUMENTS WITH CLOSURE STROKE REDUCTION ARRANGE - MENTS and in US Patent Application 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.

[0172] As can also be seen in Figures 21 and 50, a firing member or cutting member 6140 is attached to the distal end of the cutting bar 6130. The firing member 6140 is configured to interface operationally with a set 6150 slide which is operatively supported within the 5702 body of the surgical staple cartridge / clamps 5700. The 6150 slide assembly is slidably movable within the 5702 surgical staple cartridge / clamp body from a proximal starting position adjacent to a proximal end 5704 of the cartridge body 5702 to a final position adjacent to the distal end 5706 of the cartridge body 5702. The cartridge body 5702 operationally supports a plurality of clip drivers (not shown) ) which are aligned in rows on each side of a centrally arranged slot 5708. The centrally arranged slot 5708 allows the firing member 6140 to pass through the table cut and cut the fabric that is trapped between the 5810 anvil and the 5700 staple cartridge. The triggers are associated with corresponding staple pockets that open across the upper platform surface of the 5702 cartridge body. Each of the staple drivers holds one or more clamps / surgical clamps or clamps (not shown) on them. The slider assembly includes a plurality of inclined or wedge-shaped cams 6152 with each cam corresponding to a particular line of fasteners or drivers located on one side of the slot 5708.

[0173] In an exemplary form, firing member 6140 comprises a body portion 6142 that supports a knife or tissue cutting portion 6144. See Figure 50. Body portion 6142 projects through an elongated slit 5604 in the elongated channel 5602 and ends in a base member 6146 that extends laterally on each side of the body portion 6142. As the firing member 6140 is driven distally through the surgical clip / clamp cartridge 5700, the base member 6146 moves within a passage 5622 in the elongated channel 5602 which is located under the surgical staple / clamp cartridge 5700. The tissue cutting portion 6144 is disposed between a distally projecting top tip portion 6143. As can be seen further in Figures 21 and 50, firing member 6140 may additionally include two laterally extending top tabs, pins or anvil engaging features 6147. As the firing member 6140 is driven distally, a top portion of the body portion 6142 extends through an anvil slot 5814 arranged centrally and the anvil engaging features 6147 slide over the corresponding projections 5816 formed on each side of the 5814 anvil slit. More details on the firing member 6140, the 6150 slide assembly and its various alternatives, as well as examples of their operation, will be discussed in more detail below, and can also be found in the US Patent Application. serial no. 15 / 385,911, entitled SURGICAL STAPLE / FASTENERS WITH INDEPENDENTLY ACTUATABLE CLOSING AND FIRING SYSTEMS. The interchangeable surgical tool set 5000 can be operatively coupled to the handle set 500 in the manner described above in relation to the interchangeable surgical tool set 1000.

[0174] Again with reference to Figure 1, and as previously discussed, the surgical system 10 illustrated in this Figure includes four sets of interchangeable surgical tools 1000, 3000, 5000 and 7000 that can each be effectively used with the same 500 handle set to perform different surgical procedures. Turning now to Figures 22 to 24, the 7000 interchangeable surgical tool set includes a 7500 surgical end actuator comprising a first 7600 jaw and a second 7800 jaw. In one arrangement, the first jaw comprises an elongated channel 7602 which is configured to operationally support a 7700 surgical staple / clamp cartridge inside. The second claw 7800 comprises an anvil 7810 that is movably supported in relation to the elongated channel 7602. The interchangeable surgical tool set 7000 includes a hinge system 7300 comprising a hinge joint 7302 and a hinge lock 7400 that can be configured to release the 7500 surgical end actuator releasably in a desired articulated position in relation to a geometric axis of the SAa drive shaft. Details regarding the construction and operation of the 7400 articulation lock, as well as alternate locking and operational details can be found in US Patent Application Serial No. 13 / 803,086, entitled ARTICULATABLE SURGI- CAL INSTRUMENT COMPRISING AN ARTICULATION LOCK, currently US Patent Application Publication No. 2014/0263541, the description of which is incorporated herein, as a reference, in its entirety. Additional details related to the 7400 hinged lock and / or hinged lock provisions can also be found in US Patent Application Serial No. 15 / 019,196, filed on February 9, 2016,

entitled "SURGICAL INSTRUMENT ARTICULATION MECHANISM WITH SLOTTED SECONDARY CONSTRAINT” ", the description of which is incorporated herein, by reference, in its entirety.

[0175] As can be seen in Figure 24, the interchangeable surgical tool set 7000 includes a tool frame set 7200 that comprises a tool chassis 7210 that operationally supports a nozzle assembly 7240 in it. In one form, the nozzle assembly 7240 comprises nozzle portions 7242, 7244, as well as a wheel portion of the actuator 7246 which is configured to be coupled to the portions of the assembled nozzle 7242, 7244 by pressure fittings, pins, screws , etc. The interchangeable surgical tool set 7000 includes a proximal closure set 7900 that is operationally coupled to a distal closing set 8000 that is used to close and / or open the anvil 7810 of the surgical end actuator 7500, as will be discussed further in more detail below. In addition, the 7000 interchangeable surgical tool set includes a 7250 central column set that operationally supports the 7900 close closure set and is coupled to the 3500 surgical end actuator. In the illustrated arrangement, the column set center 7250 includes a distal end portion 7280 that has an opening 7281 inside to facilitate assembly. A central column cover 7283 can be attached to it to cover opening 7281 after the various components are mounted inside it. In the assembled state, a proximal end portion 7253 of the back assembly 7250 is pivoted to the chassis of the 7210 tool. In a arrangement, for example, the proximal end of the proximal end portion 7253 of the assembly 7250 dorsal bearing is attached to a dorsal bearing (not shown) that is configured to be supported within the 7210 tool chassis. This arrangement facilitates the swivel attachment of the 7250 dorsal assembly to the 7210 tool chassis, so that the 7250 dorsal assembly can selectively rotated around a geometric axis of the drive shaft SA, in relation to the tool frame 7210. In particular, in an arrangement, for example, the proximal end portion 7253 of the center column assembly 7250 includes two fittings diametrically opposed pin pins 7254 (only one can be seen in Figure 23) that are individually configured to receive a corresponding nozzle pin (not shown) extending inwardly from each of the 7242 nozzle portions,

7244. This arrangement facilitates the rotation of the central column assembly 7250 around the geometric axis of the drive axis SA. by rotating the wheel portion of actuator 7246 of the 7240 nozzle assembly.

[0176] Now with reference to Figure 24, the distal end portion 7280 of the central column assembly 7250 is attached to a segment of distal structure 7286 that operationally supports the articulation lock 7400 therein. The central column assembly 7250 is configured to, firstly, slide a set of the firing member 8110 slidingly inside and, secondly, to slide a proximal closing tube 7910 that slides extends around the center column assembly 7250. The center column assembly 7250 can also be configured to slide a 73x proximal articulation actuator slidingly. As can be seen in Figure 24, the distal structure segment 7286 is coupled pivotally to the elongated channel 7602 by an end actuator mounting assembly 7290. In one arrangement, for example, the distal end 1562 of the distal frame segment 7286 has a pivot pin 7288 formed therein. Pivot pin 7288 is adapted to be pivotally received within a pivot hole 7292 formed in the pivot base portion 7291 of the end actuator mounting set 7290. The end actuator mounting set 7290 is attached to a proximal end portion 7610 of the elongated channel 7602 by means of a spring pin 7620 or other suitable member which is received into the mounting holes 7611 in the proximal end portion 7610. The pivot pin 7288 defines an AA pivot geometry axis , which is transversal to the geometric axis of the drive shaft SA, .. See Figure 24. This arrangement facilitates the pivoting displacement (that is, the articulation) of the 7500 surgical end actuator around the geometric axis AA, of articulation in relation to to the central column assembly 7250. The segment of the distal frame 7286 is additionally configured to support the hinge lock 7400 inside. Various articulation lock arrangements can be used. At least one form of joint lock 7400 is described in more detail 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, the description of which is incorporated herein by reference in its entirety. Additional details related to the hinge lock can also be found in US Patent Application Serial No. 15 / 019,196, filed on February 9, 2016, entitled SURGICAL INSTRUMENT ARTICULATION MECHANISM WITH SLOTTED SECONDARY CONSTRAINT.

[0177] In the illustrated example, the 7500 surgical end actuator is selectively pivotable around the geometric hinge axis AA. by the 7300 hinge system. In one form, the 7300 hinge system includes the 7310 proximal hinge actuator that interfaces operationally with the 7400 hinge lock. The 7400 hinge lock includes a 7402 hinge structure that is adapted for operationally engage an actuation pin 7293 in the pivot base portion 7291 of the end actuator assembly set 7290. In addition, a cross link 7294 can be connected to actuation pin 7293 and the articulation structure 7402 to aid articulation of the 7500 surgical end actuator. As noted above, additional details related to the operation of the 7400 hinge lock and the 7402 hinge structure can be found in US Patent Application Serial No. 13 / 803,086, now Order Publication US Patent No. 2014/0263541. More details on the end actuator assembly set and the 7294 cross link can be found in US Patent Application Serial No. 15 / 019,245, filed February 9, 2016, entitled SURGI-CAL INSTRUMENTS WITH CLOSURE STROKE REDUCTION AR - RANGEMENTS, the description of which is incorporated herein, as a reference, in its entirety. As further described here, as well as in other disclosures incorporated herein by reference in the present invention, the axial movement of the 7310 proximal joint drive will result in the engagement / disengagement of the 7400 joint lock to thereby apply joint movements to the elongated channel. 7602 and thus make the surgical end actuator 7500 articulate around the geometric axis of articulation AA, in relation to the central column assembly 7250.

[0178] The anvil 7810 in the illustrated example includes an anvil body 7812 that ends at the anvil assembly portion 7820. The anvil assembly portion 7820 is movably supported over the elongated channel 7602 to perform the movement selective and axial pivot in relation to it. In the illustrated arrangement, a rotating anvil pin 7822 extends laterally away from each side of the anvil mounting portion 7820 to be received in a corresponding "kidney-shaped" opening 7613 formed in the vertical walls 7612 of the proximal end portion 7610 of the elongated channel 7602. The movement of the anvil 7810 in relation to the elongated channel 7602 is effected by the axial movement of the proximal closing system assembly 7900 and the distal closing system assembly 8000. In the illustrated arrangement, the proximal closing assembly 7900 comprises the proximal closing tube 7910 which has a proximal end 7912 and a distal end 7914. The proximal end 7912 is swiveled in a reciprocating closing element 7940 which is slidably supported within of the 7210 tool chassis, so that it can move axially in relation to it.

In one form, the reciprocating closing element 7940 includes a pair of proximally protruding hooks 7942 that are configured for attachment to the cross fixation pin 516 which is attached to the closing hinge assembly 514 of the handle assembly 500. A proximal end 7912 of the proximal closing tube 7910 is coupled to the reciprocating closing element 7940 for relative rotation with respect to it.

For example, a U-shaped connector 7944 is inserted into an annular slot 7916 at the proximal end 7912 of the proximal closing tube 7910 and is retained within the vertical slots 7946 in the mobile closing element 7940. This arrangement is for fix the proximal closing member 7900 to the reciprocating closing element 7940 for axial displacement with it, while allowing the proximal closing tube 7910 to rotate in relation to the reciprocating closing element 7940 around the geometric axis of the drive SA ,. As discussed above in connection with the interchangeable surgical tool set 1000, a closing spring (not shown) can extend over the proximal end 7912 of the proximal closure tube 7910 to prop the reciprocating closing element 7940 in the proximal direction PD that it can serve to articulate the closing trigger 512 in the handle set 500 (Figure 2) within the unacted position when the interchangeable surgical tool set 7000 is operationally coupled to the handle set 500 in the manner described above.

[0179] As can be seen in Figure 24, the distal end 7914 of the proximal closing tube 3910 is attached to the distal closing set 8000. The distal end 7914 includes the upper and lower tabs 7917, 7918 that are configured to be movably coupled to a closing sleeve of the end actuator or segment of the distal closing tube 8030. The segment of the distal closing tube 8030 includes an upper lock 8032 and a lower lock 8034 that project proximally from a proximal end of it. An upper double pivot link 8060 pivotally coupled to the upper latches 7917 and 8032 and a lower double pivot link 8064 pivotally coupled to the lower latches 7918 and 8034 together as described above. The distal advancement of the distal closing tube segment 8030 in the anvil mounting portion 7820 will result in the anvil 7810 closing or pivoting towards the elongated channel 7602. In the illustrated arrangement, a vertical anvil flap 7824 is formed over the portion anvil assembly 7820 and extends into an 8038 horseshoe-shaped opening. Opening 8038 defines an opening flap 8039 configured to operationally interface with the flap of anvil 7824 as the distal closing tube is retracted in the distal direction. Such interaction between the opening flap 8039 and the anvil flap 7824 applies an opening movement to the anvil 7810 to thereby cause the anvil 7810 to move to an open position.

[0180] In the illustrated arrangement, the 7000 interchangeable surgical tool set additionally includes a firing system generally referred to as the 8100. In several instances, the 8100 firing system includes the 8110 firing member set that is supported for displacement axial within the center column assembly 7250. In the illustrated mode, the firing member 8110 assembly includes an intermediate portion of the firing drive shaft 8120, which is configured to connect to a distal cutting portion or cutter bar 8130. The firing member assembly 8110 may 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 24, the intermediate firing drive shaft portion 8120 can include a longitudinal slot 8124 at a distal end 8122 thereof, which can be configured to receive a proximal end 8132 of the cutter bar 8130. The longitudinal slot 8124 and the proximal end 8132 of the cutter bar 8130 can be dimensioned and configured to allow relative movement between them and can comprise a sliding joint 8134. The sliding joint 8134 can allow the portion of the intermediate firing drive shaft 8120 of the firing member assembly 8110 is moved to pivot the end actuator 7500 without moving, or at least substantially moving, the cutter bar 8130, as discussed above. In the illustrated arrangement, a proximal end 8127 of the intermediate firing drive shaft portion 8120 has a firing pin for the firing drive shaft 8128 formed on it that is configured to be seated within a coupling base (no shown) which is over the distal end of the longitudinally movable drive member (not shown) of the trigger drive system 530 within the cable assembly 500, as discussed above. This arrangement facilitates the axial movement of the portion of the intermediate trigger drive shaft 8120 through the activation of the trigger drive system

530. Other clamping configurations can also be used to couple the portion of the intermediate trigger drive shaft to other trigger drive arrangements (for example, manual, robotic, etc.).

[0181] In addition to the above, the interchangeable tool set 7000 can include a coupling set 8200, which can be configured to selectively and releasably couple the proximal articulation actuator 7310 to the firing member set 8110. In In one way, the shifting assembly 8200 comprises a locking ring or locking sleeve 8210 positioned around the portion of the intermediate firing drive shaft 8120 of the firing member assembly 8110, wherein the locking sleeve 8210 can be rotated between a latched position in which the locking sleeve 8210 couples the proximal pivoting actuator 7310 to the firing member 8110 and a disengaged position, where the proximal pivoting actuator 7310 is not operably coupled to the firing 8110. As discussed above, the intermediate firing drive shaft 8120 portion of firing member 8110 is formed with an action notch namento

8126. The locking sleeve 8210 comprises a cylindrical, or at least substantially cylindrical body, which includes a longitudinal opening which is configured to receive the portion of the intermediate firing drive shaft 8120 therethrough. The locking sleeve 8210 can comprise locking protrusions diametrically opposite and facing inwards 8214, 8216 which, when the locking sleeve 8210 is in a position, are received in an engaging manner within the corresponding portions of the drive notch 8126 in the portion of the intermediate firing drive shaft 8120 and, when in another position, are not received within the drive notch 8126 to thereby allow relative axial movement between the locking sleeve 8210 and the drive shaft portion of intermediate trigger 8120, as discussed in more detail above. The locking sleeve 8210 additionally includes a locking member 8218 that is sized to be movably received within a notch 7319 at a proximal end of the proximal joint driver 7310. When the locking sleeve 8210 is in its engaged position , the locking protrusions 8214, 8216 are positioned inside a drive notch 7126 defined in the middle portion of the drive drive shaft 8120, so that a distal pushing force and / or a pulling force proximal attachment can be transmitted from the trigger member 8110 assembly to the locking sleeve 8210. Such a pulling or proximal pushing motion is then transmitted from the locking sleeve 8210 to the proximal articulation driver 7310 in order to articulate the 7500 surgical end actuator.

[0182] As discussed above, in the illustrated example, the relative movement of the locking sleeve 8210 between its engaged and disengaged positions can be controlled by the exchange set 8200 which interfaces with the proximal closing tube 7910 of the set of proximal closure 7900. The gear set 8200 additionally includes a gear switch 8240 which is configured to be received in a sliding way within a key groove (similar to key groove 2217 shown in Figure 8) formed at the perimeter external of the 8210 locking sleeve. This arrangement allows the 8240 gear shift to move axially with respect to the 8210 lock gear. The operation of the 8200 gear set may be identical to the 2200 gear set operation which has been described in more detail. above and will not be repeated again for the sake of brevity. More details, alternative provisions and drive configurations that can be used are disclosed in other provisions that can be used and which are disclosed in US Patent Application No. 15 / 385,911, entitled

SURGICAL STAPLE / FASTENERS WITH INDEPENDENTLY ACTUAL- TABLE CLOSING AND FIRING SYSTEMS, in US Patent Application Serial No. 13 / 803,086, now US Patent Application Publication No. 2014/0263541, and in US Patent Application Serial No. 15 / 019,196 , as well as other disclosures that have been incorporated into the present invention.

[0183] The 7000 interchangeable tool set may comprise a 7230 slip ring assembly that can be configured to conduct electrical energy to and / or from the 7500 surgical end actuator and / or transmit signals to and / or from surgical end actuator 7500, back to a microprocessor 560 in the handle set 500 or robotic system controller, for example, as discussed above. More details about the 7230 slip ring assembly and associated connectors can be found in US Patent Application Serial No. 13 / 803,086, currently US Patent Application Publication No. 2014/0263541 and Paid Application. try US Serial No. 15 / 019,196, each of which has been incorporated by reference in its respective entirety as well as in US Patent Application Serial No. 13 / 800,067 entitled STAPLE CARTRIDGE TISSUE THICKNESS SENSOR SYSTEM, currently Published - tion of US Patent Application serial number 2014/0263552, which is hereby incorporated by reference in its entirety.

[0184] The interchangeable surgical tool set 7000 also employs a locking system 7220 to connect, for example, removably, the interchangeable surgical tool set 7000 to the handle structure 506 of the handle set 500. The lock 7220 can be identical to the lock system 1220 described in detail above. The cutter bar 8130 may comprise a laminated beam structure that includes at least two layers of beam. Such bundle layers may comprise, for example, stainless steel bands that are interconnected, for example, by welding or fixing joints at their proximal ends and / or at other locations along their length. In alternative modalities, the distal ends of the bands are not connected to allow the laminates or bands to spread in relation to each other when the end actuator is articulated. Such an arrangement allows the 8130 cutter bar to be flexible enough to accommodate the end actuator pivot. Several laminated cutter bar provisions are presented in US Patent Application Serial No. 15 / 019,245, entitled SURGICAL INSTRUMENTS WITH CLOUD SURE STROKE REDUCTION ARRANGEMENTS, which is incorporated by reference in its entirety. As can also be seen in Figure 24, a firing drive shaft support assembly 8300 is employed to provide lateral support to the 8130 cutter bar as it flexes to accommodate the 7500 surgical end actuator joint. for the operation of the drive axle support set 8300 and the alternative cutter bar support arrangements can be found in US patent application No. 15 / 019.245, entitled SURGICAL INSTRUMENTS WITH CLOSURE STROKE REDUCTION ARRANGE - MENTS and in US Patent Application 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.

[0185] As can also be seen in Figure 24, a trigger member or cutting member 8140 is attached to the distal end of the cutter bar 8130. The trigger member 8140 is configured to make operational interface with an 8150 slide assembly which is operationally supported inside the 7702 body of the 7700 staple / surgical clamp cartridge. See Figure 51. The assembly slides

painter 8150 is slidably movable within the surgical clip / clamp cartridge body 7702 from a proximal starting position adjacent to a proximal end 7704 of the cartridge body 7702 to a final position adjacent to the distal end 7706 of the body of cartridge 7702. The cartridge body 7702 operationally supports within it a plurality of clip drivers (not shown) which are aligned in rows on each side of a centrally arranged slot 7708. Centrally arranged slot 7708 allows the member trigger 8140 pass through it and cut the fabric that is stuck between the anvil 7810 and the staple cartridge 7700. The triggers are associated with corresponding staple pockets that open across the upper platform surface of the body cartridge 7702. Each of the clamp actuators holds one or more clamps / surgical clamps or clamps (not shown) on them. The slider assembly includes a plurality of inclined or wedge-shaped cams, each cam corresponding to a particular line of fasteners or actuators located on one side of the 7708 slot.

[0186] In an exemplary form, firing member 8140 comprises a body portion 8142 that supports a knife or cutting portion of fabric 8144. See Figure 51. Body portion 8142 protrudes through an elongated slit 7604 in the elongated channel 7602 and ends in a base member 8146 that extends laterally on each side of the body portion 8142. As the firing member 8140 is driven distally through the surgical staple / clamp cartridge 7700, the base member 8146 moves within a passage 7622 in the elongated channel 7602 which is located under the staple cartridge 7700. The fabric cutting portion 8144 is disposed between a distally projecting top tip portion 8143 As can be seen further in Figure 24, firing member 8140 may additionally include two laterally extending top tabs, pins or anvil engagement features 8147. As the firing member 8140 is driven distally, a top portion of the body portion 8142 extends through an anvil slot 7814 arranged centrally and the anvil filler resources 8147 slide over the corresponding projections 7816 formed on each side anvil slit 7814. More details on firing member 8140, sliding assembly 8150 and its various alternatives, as well as examples of their operation, will be discussed in more detail below, and can also be found in the US Patent Application serial no. 15 / 385,911, entitled SURGICAL STAPLE / FASTENERS WITH INDEPENDENTLY ACTUATABLE CLOING AND FIRING SYSTEMS. The interchangeable surgical tool set 7000 can be operationally coupled to the handle set 500 in the manner described above in relation to the interchangeable surgical tool set 1000.

[0187] As can be understood from the descriptions mentioned above, the interchangeable surgical tool sets described here can be operated by the same handle set, robotic system or other automated drive system. All of the interchangeable surgical tool sets described above comprise surgical clamping and cutting instruments that have somewhat similar closing and firing components. However, the closing and firing systems and the components of each of these tool sets have differences that may seem a little subtle at first, but that, as will be further discussed below, such differences can result in improvements significant in the material composition, design, construction, manufacture and use of such tools. As will become evident according to this

Detailed Description proceed, the interchangeable surgical tool set 1000 contains subtle design differences compared to other interchangeable surgical tool sets 3000, 5000 and 7000 described here that can result in significant improvements in global functionality, in reliability and cost of the toolkit. In addition, we have found that, in some cases, a synergistic effect exists between certain component arrangements employed by the 1000 toolkit, which can further enhance the overall efficiency and functionality of the 1000 toolkit. to better understand these differences and improvements, certain components and systems of each of the tool sets 1000, 3000, 5000, 7000 will now be further described and compared to each other below.

[0188] For example, each of the interchangeable surgical tool sets 1000, 3000, 5000, 7000 needs to be able to apply a sufficient amount of clamping force to cause the claws to sufficiently grip the target tissue to allow the firing member deals properly with the tissue trapped by actuation of the firing trigger system. For example, in the illustrated sets, the respective components of the closure system need to be able to attach the anvil and the staple / surgical clip cartridge to the target tissue to allow the firing member to cut the attached tissue properly and eject rows of staples or surgical fasteners on each side of the tissue cut line. Depending on the thickness and composition of the target tissue, significant closing and firing forces are often required. In this way, the closing and firing systems in the handle assembly housing, robotic housing, etc. need to be able to generate these forces of sufficient magnitude

(using a motor or manually generated motion, for example) to close the claws sufficiently and fire the firing member through the trapped tissue. Such procedures additionally require that the components within the interchangeable drive shaft assemblies are robust enough to accommodate the magnitudes of the forces that are transmitted through them. In the past, the magnitudes of such forces often determined that components of the closing system, as well as components of the firing system, were manufactured from metal or other suitable materials with relatively large cross-section thicknesses and with substantial reinforcement configurations.

[0189] The tissue loads encountered during the pressing process typically create a large "moment" around the pivot axis of the PA anvil. The components of the closure system need to be designed to counteract that moment. In various circumstances, for example, a moment is needed around the geometric axis of pivot PA in the opposite direction. To maximize the efficiency of the system (for example, to minimize the magnitude of the applied force), the largest arm of the practical moment is desired. However, as will be discussed further below, there are tradeoffs with other design variables when trying to establish a major opposite moment. For example, there is a balance between the distance from the hinged joint to the first clamp and the length of the arm at the moment for a closing system in which the closing and firing systems are separate and distinct. The larger the moment arm of the closure system, the more efficiently it handles the staple loads and tissue compression. However, the distance between the pivot joint and the first clamp can have a major impact on the access of the surgical end actuator as it is positioned in tight spaces within a laparoscopic environment.

[0190] Figures 25 to 32 illustrate exemplary moment arms for each of the 1500, 3500, 5500 and 7500 surgical end actuators. Analyzing Figure 25 first, as described above, the 1822 anvil rotating pins extend laterally away from each side of the bib assembly 1820 to be received on a base of corresponding rotating pins 1614 formed on the vertical walls 1612 of the proximal end portion 1610 of the elongated channel 1602. The rotating pins of the anvil 1822 are hingedly attached to its base of corresponding rotating pins 1614 by the channel cover or anvil retainer 1630. The channel cover 1630 includes a pair of fixing pins 1636 that are configured to be received from retaining manner within the corresponding grooves or pin notches 1616 formed in the vertical walls 1612 of the proximal end portion 1610 of the elongated channel 1602. Such a remaining arrangement ring the anvil 1810 only to articulate around the pivot axis PA: (see Figure 3). Under such an arrangement, the anvil mounting portion 1820 does not move axially or vertically. As the segment of the distal closing tube 2030 advances in the distal direction DD under a horizontal closing force Fx; (Figure 26), the interaction between an internal cam surface 2036 in the segment of the distal closing tube 2030 and the anvil cam surface 1821 in the anvil mounting portion 1820 results in the application of a closing force Fc to the surface of anvil cam 1821. The closing force Fc: comprises the force resulting from the horizontal closing force Fx, and the vertical closing force Fy, and is essentially "normal a" or perpendicular to the cam surface 1821 on the portion of anvil assembly

1820. See Figure 26. Ma; represents an arm from the moment of closure of the pivot axis of the anvil PA: (coinciding with the center of the rotating pins of the anvil 1822) to the point of contact between the inner cam surface 2036 on the distal segment of the closing tube 2030 and the anvil cam surface 1821 on anvil mounting portion 1820 when anvil 1810 has been hinged to the fully closed position. In one example, the arm of the closing moment Mai: may be, for example, approximately 0.415 inches. Ma: x Fc: = a closing moment Cwm1 that is applied to the anvil assembly portion 1820.

[0191] To ensure that each side of the fabric cut line is secured with clips or fasteners that extend from the proximal end to the distal end of the fabric cut line, a proximal end portion 1818 of the fabric body anvil 1812 is formed with two tissue stop formations or tissue locating features 1830 extending downward from each side of the anvil body 1812 (only a stop formation of tissue 1830 can be seen in Figures 25 and 26). When the anvil 1810 is opened to receive the target tissue between the underside of the anvil and the surface of the cartridge platform, the downward extending fabric stop 1830 serves to prevent the target tissue from extending proximally beyond the staples / fasteners closer to the 1700 surgical staple / fastener cartridge. If the tissue were to extend proximally beyond the more proximal staples / fasteners, that portion of tissue could be cut by the firing member during the firing process and could not be closed, which could lead to catastrophic results. The fabric stops that extend down 1830 can prevent this from happening. As shown in Figure 26, for example, the 1720 staple / fastener pockets are shown in dashed lines in relation to the 1830 fabric stops. As can be seen in this Figure, the 1830 fabric stop has a downward extending portion 1832 and a chamfered portion 1834. The target tissue is brought into contact by the portions 1832, 1834 to prevent the target tissue from extending proximally beyond the more proximal staples / fasteners that are supported in the staple pockets / closest clamps 1720 in the staple cartridge / clamp 1702 body.

[0192] Returning again to Figure 25, as the anvil 1810 is closed over the target tissue (not shown) that is positioned between the underside or the surface in contact with the 1813 tissue of the anvil body 1812, the tissue applies the forces Tr, on the lower side 1813 of the anvil body 1812, which make the anvil 1810 experience a moment contrary to the fabric Cr: which must be overcome by the closing moment Cm: established by the components of the closing system. The example shown in Figure 25 illustrates the equally distributed tissue forces Tr, on the anvil 1810 and an arm of the Mr fabric moment; established by the trapped tissue (the trapped tissue is not shown in Figure 25, for clarity purposes). As can be seen in that Figure, in this example, the moment arm of the M 7 fabric; it is considerably longer than the arm at the time of closing Ma (ie Mr:> Mai).

[0193] Now addressing Figures 27 and 28, as described above, the rotating pins 3822 of the anvil 3810 of the interchangeable surgical tool set 3000 extend laterally away from each side of the 3820 anvil mounting portion to be received in the holes of the corresponding rotating pins 3613 formed in the vertical walls 3612 of the proximal end portion 3610 of the elongated channel 3602. Such an arrangement restricts the anvil 3810 only to pivot around the pivot pivot axis PAz (see Figure 18). Under such an arrangement, the anvil mounting portion 3820 does not move axially or vertically. As the segment of the distal closing tube 4030 advances in the distal direction

DD under a horizontal closing force Fx2 (Figure 28), the interaction between an internal cam surface 4036 in the segment of the distal closing tube 4030 and the anvil cam surface 3821 in the anvil mounting portion 3820 results in the application of a closing force Fc2 to the anvil cam surface 3821. Does the closing force Fc2 comprise the force resulting from the horizontal closing force Fx? and the vertical clamping force Fy2 and is essentially "normal a" or perpendicular to the anvil cam surface 3821 over the anvil mounting portion 3820. See Figure 28. Ma2 represents the arm of the geometry axis closing moment of the anvil pivot PA, (center of the rotating pins of the anvil 3822) to the point of contact between the inner cam surface 4036 on the distal segment of the closing tube 4030 and the anvil cam surface 3821 on the anvil mounting portion 3820 when the 3810 anvil has been pivoted to the fully closed position. In one example, the closing moment arm Ma> 2 may, for example, be approximately 0.539 inches. Ma2 x Fc2 = a closing moment Cwm2 that is applied to the anvil assembly portion 3820.

[0194] In the example shown in Figures 27 and 28, the bib body 3812 is formed with two fabric stop formations or 3830 tissue locating features that extend downward from each side of the body of the anvil 3812 (only one stop pattern of fabric 3830 can be seen in Figures 27 and 28.). When the anvil 3810 is opened to receive the target tissue between the underside of the anvil and the surface of the cartridge platform, the fabric stop formations that extend downwards 3830 serve to prevent the target tissue from extending proximally beyond clamps / clamps closest to the 3700 clamp / clamp cartridge. In the form shown in Figure 28, for example

For example, the closest 3720 staple pockets are shown in | dashed lines in relation to the 3830 fabric stop formations. As can be seen in this Figure, the 3830 fabric stop formation has a 3832 extending downward portion and a beveled portion 3834. The target fabric is placed in contact with the 3832, 3834 portions to prevent the target fabric from extending proximally beyond the closest proximal clips / fasteners that are supported in the proximal 3720 clip / fastener pockets on the 3702 staple / fastener cartridge body.

[0195] Returning to Figure 27 again, as the anvil 3810 is closed privately over the target tissue (not shown) that is positioned between the underside or the surface in contact with the 3813 tissue of the 3812 anvil body, the fabric applies the force Tr2 to the bottom side 3813 of the anvil body 3812 which causes the anvil 3810 to experience a moment opposite to the Cr2 fabric that needs to be overcome by the Cum> 2 closing moment established by the closing system components. The example shown in Figure 27 illustrates the equally distributed tissue forces Tr2 on the anvil 3810 and an arm of the Mr2 tissue moment established by the trapped tissue (the trapped tissue is not shown in Figure 27, for the sake of clarity). As can be seen in that Figure, in this example, the arm of the moment of the Mr2 fabric is considerably longer than the arm of the moment of the closing Ma> 2 (that is, Mr2> Maz).

[0196] Now approaching Figures 29 and 30, as described above, the rotating pins 5822 of the anvil 5810 of the interchangeable surgical tool set 5000 extend laterally away from each side of the 5820 anvil mounting portion to be received on the corresponding unrestricted vertical base 5613 formed on the vertical walls 5612 of the proximal end portion 5610 of the elongated channel 5602. In this arrangement, the rotating pins of the anvil 5822 are free to articulate within their respective bases 5613 as the segment of the distal closing tube 6030 comes in misaligned contact with the 5821 anvil cam surface on the 5820 anvil mounting portion. Under this arrangement, the 5810 anvil does not move axially, but the rotating pins of the 5822 anvil are free to move vertically (arrow V) within their respective bases 5613. As the segment of the closing tube distal 6030 advances in the distal direction DD under a horizontal clamping force Fx43 (Figure 30), the interaction between an internal cam surface 6036 in the segment of the distal closing tube 6030 and the anvil cam surface 5821 in the anvil mounting portion 5820 results in applying a closing force Fc3 to the 5821 anvil cam surface. The closing force Fc3 comprises the force resulting from the horizontal closing force Fu3 and the vertical closing force Fy3 and is essentially "normal a" or perpendicular to its surface. - 5821 anvil cam surface over the 5820 anvil assembly portion. See Figure 30. Ma; represents the arm of the moment of closure of the pivot axis of the anvil PA; z (coinciding with the center of the rotating pins of the anvil 5822) to the point of contact between the inner cam surface 6036 in the distal closing tube 6030 and the surface anvil cam 5821 on the anvil assembly portion 5820 when the anvil 5810 has been hinged to the closed position. In one example, the closing moment arm Ma3 can be, for example, approximately 0.50 inch. Maz3 x Fca = a Cv3 closing moment that is applied to the 5820 anvil assembly portion.

[0197] In the example shown in Figures 29 and 30, the bib body 5812 is formed with two fabric stop formations or 5830 tissue locating features that extend downward from each side of the body. anvil 5812 (only a stop formation of fabric 5830 can be seen in Figures 29 and 30.). When the anvil 5810 is opened to receive the target tissue between the underside of the anvil and the surface of the cartridge platform, the fabric stop formations that extend downwards 5830 serve to prevent the target tissue from extending proximally beyond the staples / closest clamps in the staple cartridge / surgical clamps

5700. In the embodiment shown in Figure 29, for example, the most proximal staple / fastener pockets 5720 are shown in dashed lines in relation to the 5830 fabric stop formations. As can be seen in this Figure, the formation of 5830 fabric has a downwardly extending portion 5832 and a chamfered portion 5834. The target fabric is brought into contact by the 5832, 5834 portions to prevent the target fabric from extending proximally beyond the more proximal clamps / fasteners that are supported in the closest staple / clamp pockets 5720 on the clamp / clamp cartridge body 5702.

[0198] Returning to Figure 29 again, as the anvil 5810 is closed privately over the target tissue (not shown) that is positioned between the lower side 5813 of the 5812 anvil body, the fabric applies the Tr3 forces to the side bottom or the surface of contact with the fabric 5813 of the anvil body 5812 that causes the 5810 anvil to experience a moment contrary to the Ct3 fabric that needs to be overcome by the Cum closing moment; established by the components of the closing system. The example shown in Figure 29 illustrates the equally distributed tissue forces Tr3 on the 5810 anvil and an arm of the tissue moment Mr1; 3 established by the trapped tissue (the trapped tissue is not shown in Figure 29, for the sake of clarity). As can be seen in that Figure, in this example, the arm of the moment of the Mr3 fabric is considerably longer than the arm of the moment of the closing Mas (that is, Mr13> Ma3).

[0199] Now approaching Figures 31 and 32, as described above, the rotating pins 7822 of the anvil 7810 of the interchangeable surgical tool set 7000 extend laterally away from each side of the anvil mounting portion 7820 to be received in the corresponding "kidney-shaped" opening 7613 formed in the vertical walls 7612 of the proximal end portion 7610 of the elongated channel 7602. When the anvil 7810 is in a "completely open" position, the rotating pins of the anvil 7822 can generally be located in the bottom portion 7613B of the kidney slit 7613. The anvil 7810 can be moved to a closed position by distal advancing the distal closing tube segment 8030 in the distal direction DD so that the inner cam surface 8036 at the distal end 8035 of the segment of the distal closing tube 8030 slides over an anvil cam surface 7821 that is formed over the anvil mounting portion 7820 of the anvil at

7810. As the inner cam surface 8036 at the distal end 8035 of the segment of the distal closing tube 8030 advances distally along the anvil cam surface 7821 over the anvil mounting portion 7820 under the horizontal closing force Fra (Figure 32), the segment of the distal closing tube 8030 causes the body portion 7812 of the anvil 7810 to articulate and move axially in relation to the 7700 staple / surgical clip cartridge as the rotating pins of the anvil 7822 moves upward and distally into the kidney slits 7613. When the distal closing tube segment 8030 reaches the end of its closing stroke, the distal end 8035 of the distal closing tube segment 8030 is contiguous / comes into contact with an abrupt anvil protrusion 7823 and serves to position the anvil 7810, so that the forming pockets (not shown) on the underside or on the contact surface with the fabric 7 813 of the body portion 7812 are properly aligned with the staples / fasteners on the staple / fastener cartridge. The anvil protrusion 7823 is defined between the anvil cam surface 7821 on the anvil mounting portion 7820 and the anvil body portion 7812. In other words, in this arrangement, the anvil cam surface 7821 does not extend to the outermost surface 7817 of the anvil body 7812. When in this position, the rotating pins of the anvil 7822 are located in the top portions 7613T of the renal slots 7613. Ma represents the moment arm from the pivot axis of the anvil PA . (coinciding with the center of the rotating pins of the anvil 7822) when the rotating pins 7822 are located in the top portions 7613T of the kidney slots 7613, as shown. In one example, the arm of the moment Mas can be, for example, approximately 0.184 inches. Mas x FHa = a closing moment Cma that is applied to the anvil mounting portion 7820.

[0200] In the example shown in Figures 31 and 32, the anvil body 7812 is formed with two fabric stop formations or 7830 fabric locator formations that extend downward from each side of the anvil body 7812 (only one stop pattern of fabric 7830 can be seen in Figures 31 and 32). When the anvil 7810 is opened to receive the target tissue between the underside of the anvil and the surface of the cartridge platform, the fabric stop formations that extend downwards 7830 serve to prevent the target tissue from extending proximally beyond staples / fasteners closest to the 7700 staple cartridge / surgical fasteners. In the embodiment shown in Figure 31, for example, the closest staple pockets / fasteners 7720 are shown in dashed lines in relation to the fabric stopper 7830. As can be seen in this Figure, the fabric stopper formation 7830 has a downward portion 7832 and a chamfered portion 7834. The target tissue is brought into contact by portions 7832, 7834 to prevent the target tissue from extending proximally beyond the most proximal clips / fasteners that are supported in the most proximal staple / fastener pockets 7720 on the 7702 clip / fastener body.

[0201] Returning again to Figure 31, as the anvil 7810 is closed privately over the target tissue (not shown) that is positioned between the underside or the surface in contact with the tissue 7813 of the body portion of the anvil 7812, the fabric applies the forces Tra to the lower side 7813 of the anvil body 7812 which causes the anvil 7810 to experience a moment contrary to the Cra fabric that needs to be overcome by a closing moment Cma established by the components of the closing system. The example shown in Figure 31 illustrates the equally distributed fabric forces Tra on the 7810 anvil and an arm of the Mr. fabric moment established by the attached fabric (the attached fabric is not shown in Figure 31, for the sake of clarity) . As can be seen in that Figure, in this example, the arm of the Mr fabric moment is considerably longer than the arm of the Maas closure moment (that is, Mrs> Mas).

[0202] The exemplary interchangeable surgical tool sets illustrated 1000, 3000, 5000, 7000 comprise surgical stapling devices that employ "separate and distinct" closing and firing systems. In other words, the closing system used to close the claws is operable separately from the firing system used to drive the firing member through the staple cartridge / surgical fasteners to cut and secure the tissue. These separate and distinct locking and firing systems can be distinguishable from those surgical stapling instruments in which the triggering system action to advance the firing member is necessary to move the claws from an open position to a closed position.

As will be discussed in more detail below, however, the firing members of some of the interchangeable surgical tool sets disclosed here can also apply additional closing movements to the anvil as the firing member is fired (ie, advanced distally through the surgical end actuator). As can be seen from the reference to Figures 25-32, in the illustrated examples, Ma2> Mas> Ma:> Mas.

Figures 25, 27, 29 and 31 also illustrate the resistive forces established by the fabric during the closing process.

Tr represents the force generated by the tissue when the tissue is trapped between the anvil and the staple cartridge.

These forces establish an opposite moment Cr that is applied to the anvil around the point / area where the segment of the distal closing tube is in cam contact with the anvil cam surface in the anvil mounting portion.

In these illustrated examples, the tissue moment arm for each surgical instrument (tool set) is generally larger than the closure moment arm for that instrument.

It can be understood from the difference between an arm of the typical tissue moment found when picking the tissue between the anvil and the clip of surgical clips / fasteners and the arm of the instrument closing moment results in the need to apply forces enough closure by the segment of the closing tube distal to the anvil to close the anvil sufficiently on the tissue.

Thus, the segment of the distal closing tube needs to be strong and robust enough to handle the considerable stresses formed during the closing process.

To establish a state of tension in the segment of the distal closing tube that most closely resembles a state of "circumferential tension" instead of a state of "ring tension", the side walls of the segment of the closing tube distal can be thickened in order to come into contact with the side walls and the corresponding anvil mounting portions of the elongated channel. This arrangement can also add tension to the structure similar to the overall rim of the pipe. Maximizing the thickness on the anvil side of the distal closing tube segment can also increase the strength of the tube segment (rim) while allowing space for a large bearing or cam surface to misalign the anvil down towards the cartridge. Patent application serial number 15 / 385,911, entitled SURGICAL STAPLE / FASTE-

NERS WITH INDEPENDENTLY ACTUATABLE CLOSING AND FIRING SYSTEMS, reveals several segment configurations of the distal closure tube, which can be used in the various sets of interchangeable surgical tools disclosed here.

[0203] The discussion and previous comparisons may illustrate that designs of the closing system that have large arms of the closing moment can lead to better efficiencies of the components of the closing system and can reduce the amount of forces of closure that are necessary to achieve total closure of the anvil on the tissue. However, as noted above, there can be disadvantages with other design variables when trying to maximize the closing moment arm. For example, another desirable attribute refers to "opening the claw". The "claw opening" can refer to a distance since it is measured from the middle of a more distal clamp center or fastener along a line that is perpendicular to the corresponding most distal clamp forming pocket on the bottom side or contact surface of the surface of the anvil body portion. Figure 33 illustrates the jaw opening Ja: for the surgical end actuator 1500. In the illustrated example, the more distal clamp / clamp pockets 1730 contain the clamps or clamps

more distal pains (not shown) in them.

Each more distal clamp or clamp corresponds to a more distal clamp-forming pocket / clamp 1815 (shown in dashed line in Figure 33) that is formed on the underside or surface of contact with the fabric 1813 of the anvil body 1812 The distance Ja, between the most distal clamp / clamp pocket 1730 and the corresponding most distal clamp / clamp pocket 1815 is the "claw opening" for the 1500 surgical end actuator. at least one modality, for example, Ja is approximately 1.207 inches.

Figure 34 illustrates the Jar jaw opening for the 3500 surgical end actuator. In the illustrated example, the most distal clamp / clamp pockets 3730 contain the most distal clamps or clamps (not shown) in them.

Each more distal clamp or fastener corresponds to a more distal clamp-forming pocket / fastener 3815 that is formed on the underside or surface of contact with fabric 3813 of the 3812 anvil body. The distance Ja? between the most distal clamp J / clamps 3730 and the corresponding pocket the most distal clamp forming pocket / clamp 3815 is the "claw opening" for the 3500 surgical end actuator. In at least one embodiment, for example, Ja? is approximately 0.781 inches.

Figure 35 illustrates the Jaz jaw opening for the 5500 surgical end actuator. In the illustrated example, the most distal clamp / clamp pockets 5730 contain the most distal clamps / clamps (not shown there). Each more distal clamp / fastener corresponds to a 5815 more distal clamp-forming pocket / fastener that is formed on the underside or surface of contact with the 5813 fabric of the 5812 anvil body. The distance Jaz between the most distal clamp / fastener pocket 5730 and the corresponding most distal clamp-forming pocket / fastener 5815 is the "jaw opening" for the 5500 surgical end actuator. In at least one embodiment, for example, Ja3 is approximately 0.793 inches.

Figure 36 illustrates the Jas jaw opening for the 7500 surgical end actuator. In the illustrated example, the most distal clamp / clamp pockets 7730 contain the most distal clamps or clamps (not shown) in them. Each more distal clamp or clamp corresponds to a more distal clamp-forming pocket / clamp 7815 that is formed on the underside or surface of contact with the 7813 tissue of the 7812 anvil body. The Jas distance between the most distal clamp J / 7730 fasteners and the corresponding pocket for the most distal clamp-forming pocket / fastener 7815 is the "claw opening" for the surgical end actuator 7500. In at least one embodiment, for example, Ja, is approximately 0.717 inch. Thus, for these Examples, Ja:> Jaz> Jaz> Jaa. As such, comparatively, the surgical end actuator 1500 has the largest claw opening.

[0204] In these surgical end actuator designs that employ separate and distinct closing and firing systems that use an axially movable closing ring or distal closing tube segment as the examples described above, the interrelationships between the anvil or the pivot geometric axes of the Pa claw and the distal end of the segment of the distal closing tube, as well as the strength of the anvil mounting portion, can determine the magnitude of the claw opening that is achievable for each end actuator design specific. These interrelationships can be better understood from, for example, the reference to Figure 37. Figure 37 shows a 1500R surgical end actuator using an anvil 1810R that has an anvil mounting portion 1820R that is shown in solid lines . The anvil mounting portion 1820R includes rotating anvil pins 1822R that define an even reference pivot geometry axis around which the anvil mounting portion 1820R can pivot with respect to an elongated channel.

1602R cattle.

The 1500R surgical end actuator also employs a segment of the distal closing tube 2030R that has a distal end 2035R that is configured to come into contact with the anvil mounting portion 1820R in the various ways discussed above.

A 1700R surgical staple / clamp cartridge is supported on the elongated channel 1602R and has a cartridge platform surface or 1710R tissue contact surface.

Figure 37 represents a distance between the reference pivot axis Par and the distal end 2035R of the segment of the distal closing tube 2030R.

Figure 37 illustrates the 1810R anvil in solid lines.

The anvil body 1812R is in its maximum open position when the segment of the distal closing tube 2030R is in its initial position most proximal to the anvil mounting portion 1820R.

The maximum APAr opening angle for this configuration is, for example, approximately ten degrees.

This APAr opening angle is typical for many end actuator arrangements.

In another end actuator arrangement, the opening angle is 12.25 degrees.

In one arrangement, for example, D; can be approximately 0.200 inch.

To obtain an APAr opening angle: greater than, for example, twenty-two degrees, if the relationship between the distal end 2035R of the segment of the distal closing tube 2030R and the geometric axis of the PaR reference pivot remains unchanged, then a width in cross section Mw of an anvil mounting portion 1820R ;, it must be undesirably reduced.

The 1810R; anvil is illustrated by dashed lines.

As can be seen in this figure, an abrupt protrusion must be formed between the anvil body 1812R: and the anvil mounting portion 1820R1, so that its width in cross section is reduced.

The APAr opening angle: is measured from the bottom side 1813R: from the anvil body 1812R; and the 1710R platform surface of the 1700R surgical clamp / clamp cartridge. Such a reduction in the robustness of the anvil mounting portion of the anvil can lead to reduced anvil reliability and is less desirable than anvils that have anvil mounting portions with larger cross-section profiles.

[0205] Now with reference to Figures 38 and 39, increases in the claw opening (or opening angle) can be more easily achieved as the pivot or pivot axis PA moves closer to the distal end of the initial or proximal position of the distal closing tube segment. Figure 38 illustrates a surgical end actuator 1500 'which is substantially similar to the surgical end actuator 1500, except for the location of the pivot geometry axis PA' in relation to the distal end 2035 of the distal closing tube segment 2030. As can be seen in that Figure, the distance between the pivot geometric axis PA 'and the distal end 2035 of the distal closing tube segment 2030 when the distal closing tube segment 2030 is in its closest starting position is represented by DP 'and the opening angle is APA. In other words, when the segment of the distal closing tube 2030 is in its initial position which corresponds to the completely open position of the anvil 1810, the distal end 2035 of the same is on an RF reference plane that is perpendicular to the said geometric axis of the drive shaft SA. The distance between the pivot geometry axis PAN 'and the reference plane RF', measured along a line that is perpendicular to the reference plane RF 'and extends through the pivot drive axis PA' is DP '. In at least one arrangement, the DP 'is approximately 0.200 inches and the APA opening angle can be approximately 10 degrees.

[0206] Figure 38 illustrates the APA opening angle of a 1500 'surgical end actuator with a distance DP' between the reference pivot geometry axis PA 'and the distal end 2035 of the closing tube segment. distal 2030. Turning to Figure 39, as can be seen in this figure, the distance DP between the pivot geometric axis PA and the RF reference plane on which the distal end 2035 of the segment of the distal closing tube 2030 is located when the segment of the distal closing tube 2030 is in its most proximal initial position it is less than the distance DP 'and the APA opening angle; is greater than PAC. For example, in at least one mode, the DP distance is approximately 0.090 inches and the APA opening angle is approximately twenty-two degrees. In this way, by moving the pivot geometric axis PA closer to the distal end of the segment of the distal closing tube when the segment of the closing tube is in its closest starting position, the opening of the claw can be significantly increased without the need to reduce the width of the cross section of the anvil mounting position. This can represent a significant improvement over other provisions of the surgical end actuator. In various circumstances, the center of the rotating pins of the anvil 1822 can ideally be located between 0.010 and 0.060 inches from the distal end 2035 of the distal closure tube segment 2030 when the distal closure tube is in position initial (more proximal). A maximum distance for large claw applications can be, for example, 0.090 inches. As can also be seen in Figure 39, when the anvil 1810 is in its fully open position, as shown, the downwardly extending portion 1832 of the fabric stop 1830 generally stops on the deck surface of the staple cartridge 1710 to prevent any proximal movement of the target tissue during grip.

[0207] Figures 40 and 41 illustrate the arrangements of the tissue stop or tissue locator 1830 employed in a form of the surgical end actuator 1500. As indicated above, the tissue stops 1830 comprise a portion extending downwards 1832 and a chamfered portion 1834. The downwardly extending portion 1832 comprises a distal edge 1833 ending at a distal corner portion 1835. Figure 40 illustrates anvil 1810 in its fully open position. The bottom side 1813 of the anvil body 1812 is positioned at an APA opening angle. In at least one arrangement, the APA opening angle; it is greater than 12.25 degrees (12.25 degrees) and can be as large as eighteen degrees (18 degrees). When in this fully open position, the surgical end actuator 1500 can additionally have a proximal opening ParPP1 which, in at least one arrangement, can be, for example, approximately 0.254 inch. The proximal opening defines how much the tissue can be positioned between the proximal portions of the claws (anvil and cartridge). A large proximal opening can be more advantageous, for example, when cutting and trapping lung tissue that can be partially inflated when it is introduced between the anvil and the cartridge. The proximal opening can be measured from the center of the pocket or pair of fastener pockets most proximal directly vertical to the contact surface of the lower fabric or the fabric on the anvil body.

[0208] When the anvil 1810 is in the fully open position, as shown in Figure 40, the distal corner 1835 does not extend above the 1710 cartridge platform surface to prevent the tissue from moving from the proximal to the most proximal clamp in the most proximal staple pockets 1720. In at least one fashion, a stop portion of the vertical channel 1619 can extend upward from the side walls of the elongated channel 1602 to match each corresponding fabric stop 1830 to additionally avoid any proximal tissue infiltration between the fabric stop 1830 and the stop portion of the channel 1619. Figure 41 illustrates the anvil 1810 in a completely closed position. When in this position, the distal edges 1833 of the fabric stops 1830 are approximately aligned or coincident with the locations of the closest clamps / fasteners on the 1700 staple / fastener cartridge. The distance from the geometric hinge axis AA: for most proximal clamps / fasteners is identified as Tsp1. In one arrangement, Tsp: has, for example, approximately 1.044 inches. When the anvil 1810 is completely closed, the fabric stops 1830 can be sized and shaped in relation to the proximal end portion 1610 of the elongated channel 1602 in order to facilitate easy insertion through a standard trocar of corresponding size. In at least one example, the fabric stops 1830 of the anvil 1810 are dimensioned and shaped in relation to the elongated channel 1602 in order to allow the surgical end actuator 1500 to be inserted through a conventional 12 mm trocar.

[0209] Figures 42 and 43 illustrate the arrangements of the fabric stop 3830 employed in a form of the surgical end actuator 3500. As indicated above, the fabric stops 3830 comprise a portion extending downwards 3832 and a chamfered portion 3834. The downwardly extending portion 3832 comprises a distal edge 3833 ending at a distal corner portion 3835. Figure 42 illustrates anvil 3810 in its fully open position. The bottom side 3813 of the anvil body 3812 is positioned at an opening angle APA2. In at least one arrangement, the APA opening angle is approximately thirteen and a half degrees (13.5º). When in this fully open position, the 3500 surgical end actuator can additionally have a ParP2 proximal opening which, in at least one arrangement, can be, for example, approximately 0.242 inch. When the anvil 3810 is in the fully open position, as shown in Figure 42, the distal corner 3835 does not extend above the 3710 cartridge platform surface to prevent the fabric from moving from the clips / fasteners proximal to most proximal in the most proximal 3720 clamp / clamp pockets. Figure 43 illustrates anvil 3810 in a completely closed position. When in this position, the distal edges 3833 of the fabric stops 3830 are approximately aligned or coincident with the locations of the closest staples / fasteners on the 3700 staple / fastener cartridge. The distance from the hinge axis AA> for the closest clamps / fasteners it is identified as Tsp2. In one arrangement, Tsp2 is, for example, approximately 1.318 inches.

[0210] Figures 44 and 45 illustrate the provisions of the 5830 fabric stopper employed in a shape of the 5500 surgical end actuator. As indicated above, the 5830 fabric stoppers comprise a downwardly extending portion 5832 and a chamfered portion 5834. The downwardly extending portion 5832 comprises a distal edge 5833 ending at a distal corner portion 5835. Figure 44 illustrates anvil 5810 in its fully open position. The lower side 5813 of the anvil body 5812 is positioned at an APA3z opening angle. In at least one arrangement, the APA opening angle; it is approximately eight degrees (8th). When in this fully open position, the surgical end actuator 5500 can additionally have a proximal opening Papp3 which, in at least one arrangement, can be, for example, approximately 0.226 inches. When the anvil 5810 is in the fully open position, as shown in Figure 44, the distal corner 3835 extends slightly above the surface of the cartridge platform

5710. Figure 45 illustrates the 5810 anvil in a completely closed position. When in this position, the distal edges 5833 of the 5830 fabric posts are approximately aligned or coincident with the locations of the closest clips / fasteners on the 5700 staple / fastener cartridge. The distance from the AA artifact geometric axis; 3 for the closest clamps / fasteners is identified as Tsp3. In one arrangement, Tsp3 is, for example, approximately 1,664 inches.

[0211] Figures 46 and 47 illustrate the arrangements of the tissue stop 7830 employed in a form of the surgical end actuator 7500. As indicated above, the tissue stops 7830 comprise a portion extending downwards 7832 and a chamfered portion 7834. The downwardly extending portion 7832 comprises a distal edge 7833 ending at a distal corner portion 7835. Figure 46 illustrates anvil 7810 in its fully open position. The bottom side 7813 of the anvil body portion 7812 is positioned at an APA opening angle. In at least one arrangement, the APA opening angle is approximately ten degrees (10º). When in this fully open position, the 7500 surgical end actuator can additionally have a proximal Papra opening which, in at least one arrangement, can be, for example, approximately 0.188 inch. When the anvil 7810 is in the fully open position, as shown in Figure 46, the distal corner portion 7835 extends slightly below the surface of the 7710 cartridge platform to prevent the fabric from getting close to the closest clamps / fasteners in the closest staple pockets 7720. Figure 47 illustrates the 7810 anvil in a completely closed position. When in this position, the outer edges 7833 of the fabric stops 7830 are approximately aligned

mismatched or coincident with the locations of the closest clamps / fasteners in the 7700 staple / fastener cartridge. The distance from the AA pivot axis for the closest clamps / fasteners is identified as Tsva. In one arrangement, Tspa is, for example, approximately 1.686 inches.

[0212] In various circumstances, the relations of the firing member in relation to the geometric axis of articulation AA, as well as the geometric axis of the PA claw pivot around which the anvil is articulated, can affect the length of the arrangement of the articulation joint. Obviously, the longer articulation joint arrangements can adversely affect the maneuverability of the end actuator within tight spaces and also limit the magnitude of the jaw opening that can ultimately be reached by the end actuator. Figure 48 illustrates the surgical end actuator 1500 in a fully open position. That is, the anvil 1810 has been pivoted to its fully open position and the firing member 2140 is in its starting or starting position. The distance between the distal end of each of the coupling features of the anvil 2147 and the geometric axis of articulation AA: is represented by AJD :. In at least one example, AJD: is approximately 0.517 inches. For comparison and in reference to Figure 49, the AJD distance? from the distal end of each of the coupling features of the 4147 anvil and the hinge axis AA, it is, in at least one example, approximately 0.744 inch. With reference to Figure 50, the distance AJD3 from the distal end of each of the coupling features of the anvil 6147 and the geometric axis of articulation AA; it is, in at least one example, approximately 1.045 inches. Turning to Figure 51, the AJD distance. from the distal end of each of the engaging features of the anvil 8147 and the geometric axis of articulation AA, it is, in at least one example, approximately 1.096 inches. Thus, as can be seen from this comparison, the articulation joint arrangement (as measured by the distances AJD1, AJD2, AJD3, AJD4) of the surgical end actuator 1500 is more compact and, therefore, can be more maneuverable than 3500, 5500 and 7500 surgical end actuators in at least some surgical applications.

[0213] Another factor that can affect the length of the joint arrangement refers to the location of the firing member in relation to the geometrical axis of the anvil pivot PA around which the anvil articulates. For example, Figure 52 illustrates the anvil 1810 of the surgical end actuator 1500 in its fully open position. When in this position, the firing member 2140 is in its parked or "home" position. As can be seen in that Figure, a useful metric for comparing the "compactness" of the articulation joint arrangement is the distance from the proximal flap TD, between the proximal end 2149 of each of the top anvil engaging features 2147 and the pivot axis of the PA anvil. In at least one preferred arrangement, the distance from the proximal flap TD: is approximately greater than thirty-five percent (35%) of the total length TL, 1 of each of the anvil hitching features 2147 when the anvil 1810 is in a completely open position and firing member 2140 is in its most proximal or initial position. In other words, when the anvil 1810 and the firing member 2140 are in the positions described above, at least 35% of each of the engaging features of the anvil 2147 extends proximally beyond the geometric pivot axis of the PA anvil. Figure 53 illustrates the end actuator 1500 with the anvil 1810 in the closed position and the firing member 2140 in its most proximal or initial position. As can be seen in this figure, at least 35% of each of the coupling features of the anvil 2147 extends proximally beyond the pivot geometry axis of the anvil PA :.

[0214] Figure 54 illustrates the position of the firing member 4140 of the surgical end actuator 3500 when the anvil 3810 is in its fully open position and the firing member 4140 is in its most proximal or initial position. As can be seen in this Figure, each of the coupling features of anvil 4147 is completely distal to the geometric axis of the anvil pivot PA, thus resulting in a longer articulation joint arrangement. Thus, the TD distance is the distal distance between the proximal ends 4149 of the anvil engaging features 4147 and the pivot axis of the anvil PA. Figure 55 illustrates the position of firing member 6140 of surgical end actuator 5500 when anvil 5810 is in its fully open position and firing member 6140 is in its most proximal or initial position. As can be seen in this Figure, each of the engaging features of the anvil 6147 is completely distal to the geometric axis of the anvil pivot PAs; thus resulting in a longer articulation joint arrangement. In this way, the distance TD; 3 is the distal distance between the proximal ends 6149 of the coupling features of the anvil 6147 and the pivot geometric axis of the PAsz anvil. Figure 56 illustrates the position of the shooting member 8140 of the surgical end actuator 7500 when the anvil 7810 is in its fully open position and the shooting member 8140 is in its most proximal or initial position. As can be seen in this figure, each of the engaging features of the anvil 8147 is completely distal to the geometric axis of the pivot of the anvil PA., Thus resulting in a longer articulation joint arrangement. Thus, the TD distance is the distal distance between the proximal ends 8149 of the anvil hitch features 8147 and the pivot geometric axis of the PA anvil.

the surgical end actuator 1500 is the only surgical end actuator in which a portion of the anvil engaging features on the firing member extends proximally beyond the anvil's geometric pivot axis when the firing member is in its most proximal or initial position. The anvil engaging features of each of the firing members of the 3500, 5500 and 7500 surgical end actuators are completely distal from their respective anvil pivot geometry axes when the firing members are in position more proximal or initial. Further analyzing this comparison, for example, the surgical end actuator 1500 is the only surgical end actuator in which at least thirty-five percent (35%) of the anvil engagement resources reside between the geometric axis of anvil pivot and geometric axis of articulation when the firing member is in its initial position and the anvil is fully open. Similar comparisons can be made by comparing the same distances between the location of the lower channel engaging resources in the firing member in relation to the geometric axis of the claw pivot when the firing member is in its most proximal initial position.

[0215] Another metric that can be used to assess the compactness of the articulation joint arrangement may comprise comparing the ratio between the distance from the geometric axis of articulation and the distal end of the anvil engaging features on the firing member (distances AJD1, AJD2, AJD3, AJDa - Figures 48-51) in relation to the distance from the geometric axis of articulation to the distal edge of the fabric stops or the most proximal clamp / fastener (distances TSD1, TSD> 2 , TSD3, TSD, - Figures 41, 43, 45, 47) for each end actuator. For example, in a preferred arrangement, AJD / TSD <0.500. The AJD / TSD ratio can be referred to in the present invention

"compactness ratio" for that specific surgical end actuator. In an arrangement, for example, for the 1500 end actuator, AJDVTSD: = 0.517 inch / 1.044 inch = 0.495. In an example illustrated for the 3500 end actuator, AJD2 / TSD> 2 = 0.744 inch / 1.318 inch = 0.564. In an illustrated example for the 5500 end actuator, AJD3 / TSD3 = 1,045 inches / 1,664 inches = 0.628. In an illustrated layout, AJDVTSD. = 1.096 inch / 1.686 inch = 0.650. Thus, in at least one preferential arrangement in which the joint joint arrangement is the most compact, has the largest claw opening and is the most maneuverable, the ratio between the distance from the geometric axis of articulation to the proximal end of the anvil engaging features on the firing member and the distance from the geometric axis of articulation to the distal edge of the fabric stops or the most proximal clamp / fastener is approximately less than 0.500.

[0216] Figures 57 to 61 illustrate a progressive closing arrangement for moving the anvil 1810 of the surgical end actuator 1500 from a fully open position to a closed position and then to a more closed position. Figures 57 and 58 illustrate the anvil 1810 in a closed position. In both Figures, the 2030 distal closure tube segment was advanced in the distal DD direction to its completely closed position. As discussed above, the interaction between an inner cam surface 2036 in the segment of the distal closing tube 2030 and an anvil cam surface 1821 in the anvil mounting portion 1820 causes the anvil 1810 to revolve to the closed position. As can be seen in Figure 58, the staple-forming bottom or fabric contact surface 1813 of the anvil body 1812 can be relatively parallel and spaced with respect to the cartridge platform surface 1710 of the staple cartridge / surgical fastener . When in that initial closed position, firing member 2140 is in its starting position, as can be seen in Figure 57. When in this position, the engaging features of anvil 2147 of firing member 2140 did not engage with anvil 1810 , but they are in substantially horizontal alignment with the projections 1816 formed on the anvil 1810. In at least one arrangement, a ramp segment 1829 is formed proximal to each of the horizontal projections 1816 of the anvil. Figure 59 illustrates the position of the firing member 2140 after it has advanced distally to a point where the engagement features of the anvil 2147 initially engaged the horizontal projections of the anvil 1816 on the anvil 1810, and Figure 61 illustrates the position of the firing member 2140 and the anvil 1810 so that the engaging features of the anvil are fully engaged with the protrusions of the anvil 1816 to apply an "excessive closing" force to the anvil 1810 as the firing member 2140 continues to advance distally. In at least one arrangement, as shown in Figure 61, for example, when the anvil 1810 is in the most closed position (no tissue stuck between the anvil and the cartridge), the distal portion of the anvil 1810 will come into contact with the surface of the 1710 cartridge platform. As a result of such a configuration, the force required to advance the firing member distally from its initial position to its final position within the end actuator may generally be less than other provisions of the surgical end actuator that does not use such progressive closing arrangements.

[0217] Figure 62 illustrates the anvil 1810 of the surgical end actuator 1500 in a fully open position. As discussed above, each of the rotating pins of the anvil 1822 is received on a corresponding rotating pin base 1614 that is formed on the vertical walls 1612 of the proximal end portion 1610 of the elongated channel 1602. The rotating pins of the anvil 1822 are pivotally retained at their corresponding rotating pin bases 1614 by the channel cover or anvil retainer 1630. The channel cover 1630 includes a pair of fixing pins 1636 that are configured to be received retentively within the grooves or corresponding pin indentations 1616 formed in the vertical walls 1612 of the proximal end portion 1610 of the elongated channel 1602. During a portion of the closing stroke for the anvil 1810 in the individual tissue, the counter-forces established during the process of gripping the tissue push the rotating pins of the anvil 1822 away from their respective rotating pin bases 1614. The cover of the channel 1630 includes a pair of portions of the slot cover 1632 corresponding to each rotating pin base 1614. When the channel cover 1630 is installed in the proximal end portion 1610 of the elongated channel 1602, each portion of the slot cover 1632 serves to retain the pins rotors of the anvil 1822 within their respective rotating pin bases 1614 during the closing process. As can be seen in Figures 62 and 63, each portion of the slit lid 1632 can have an arched bottom portion 1638 that is configured to pivot the corresponding rotating pins of the anvil 1822. Each slit lid 1632 can be shaped wedge to completely block the open end of the rotating pin bases

1614. Such an arrangement of the channel cover 1630 can increase the ease of mounting the anvil 1810 to the elongated channel 1602. Once the rotating pins of the anvil 1822 have been placed in their respective rotating pin bases 1614, the cover of the anvil channel 1630 can be installed as shown. In at least one arrangement, the distal closing tube segment 2030 serves to hold the cover of channel 1630 in the position that serves to prevent the rotating pins of the anvil 1822 from moving vertically on their respective rotating pin bases 1614 during closing, as shown in Figure 63. In another arrangement, the fixing tabs 1636 may be chafed within their respective notches 1616 or otherwise be retained thereon by means of an adhesive or other fixation means.

[0218] The four interchangeable tool sets 1000, 3000, 5000 and 7000 employ different claw opening configurations to facilitate moving the anvil from a closed position to a fully open position. For example, the distal closing tube segment 4030 of the interchangeable tool assembly 3000 includes positive 4040 claw or anvil opening features that correspond to each side wall of the distal closing tube segment 4030 and project into it . The 4040 positive anvil opening features extend inwardly through the corresponding openings in the transitional side walls and can be welded to the 4030 distal closing tube segment. In this arrangement, the positive positive anvil opening features are axially aligned between themselves and are configured to make operational interface with the corresponding opening ramps formed on the undersides of the anvil mounting portion 3820. When the anvil 3810 and the distal closing tube segment 4030 are in their completely closed positions, each of the anvil 4040 positive opening features is located in a cavity that is established between the anvil opening ramps and the bottom portion of the elongated channel 3602. When in this position, the 4040 positive anvil opening features do not come into contact with the anvil mounting portion 3820 or at least may not apply any opening movements or forces significant to them. When the distal closing tube segment 4030 is moved in the proximal direction, the 4040 anvil opening features are brought into contact with the anvil opening ramps to cause the 3810 anvil to pivot to an open position. More details on the 4040 positive anvil opening features can be found in US Patent Application Serial No. 15 / 385,911, entitled SURGICAL STAPLE / FASTENERS WITH INDEPENDENTLY ACTUAL TABLE CLOSING AND FIRING SYSTEMS.

[0219] Regarding the surgical end actuator 5500 of the tool set 5000, the segment of the distal closing tube 6030 includes two positive opening tabs of the anvil that extend inward 6038 that can be pushed into the wall of the segment of the anvil distal closure tube 6030. See Figure 21. In the illustrated arrangement, tabs 6038 are axially aligned with each other and are configured to contact the corresponding vertical anvil tails 5827 formed on the anvil assembly portion 5820. When the distal closing tube segment 6030 is moved in the proximal direction, the anvil opening features 6038 are brought into contact with the 5827 anvil tails to cause the 5810 anvil to pivot to an open position.

[0220] Regarding the surgical end actuator 7500 of tool set 7000, a positive opening motion of the anvil is applied to the anvil 7810 by the segment of the distal closing tube 8030 when the segment of the distal closing tube 8030 is moved proximally. As discussed above, a vertical anvil flap 7824 is formed over the anvil mounting portion 7820 and extends into the horseshoe-shaped opening 8038 in the segment of the distal closing tube 8030. See Figure 24. The opening 8038 defines an opening flap 8039 that is configured to interoperate with the anvil flap 7824 as the segment of the distal closing tube 8030 is retracted in the distal direction.

Such interaction between the opening flap 8039 and the anvil flap 7824 applies an opening movement to the anvil 7810 to thereby cause the anvil 7810 to move to an open position.

[0221] In relation to the surgical end actuator 1500 of the interchangeable tool set 1000, in the example shown, the segment of the distal closing tube 2030 employs two axially displaced resources, distal and proximal, with positive claw opening 2050 and 2040, as illustrated in Figures 64 to 77. As can be seen in Figures 64 and 65, the positive opening feature of the proximal jaw 2040 is axially proximal to the positive opening feature of the distal jaw 2050 by an axial displacement distance AOF (“axial offset distance ”). In Figure 65, the positive opening feature of the 2040 claw is located on the right side (as seen by a tool set user) of the geometric axis of the SA drive shaft. Figures 66, 72 and 73 illustrate the position of the positive opening feature of the proximal claw 2040 when the anvil 1810 is in the closed position. As can be seen more particularly in Figure 66, when in this position, the positive opening feature of the proximal claw 2040 is on a right side or in the first relieved area 1825 formed in the anvil mounting portion 1820. Figures 69, 72 and 73 illustrate the position of the positive opening feature of distal claw 2050 when anvil 1810 is in the closed position. As can be seen more particularly in Figure 69, when in this position, the positive opening feature of the distal claw is in contact with a stepped portion 1823 of the anvil cam surface 1821.

[0222] To initiate the opening process, the jaw closure system is actuated to move the 2030 distal closure tube segment in the proximal direction PD. As the segment of the distal closing tube 2030 moves in the proximal direction PD, the positive opening feature of the proximal jaw 2040 comes into contact with a first jaw opening cam surface or right jaw opening cam surface 1826 and begins to apply a claw opening movement to the anvil 1810. See Figures 67, 74 and 75. As can be seen in Figures 70, 74 and 75, during this proximal movement of the segment of the distal closing tube 2030, the feature positive opening opening of the distal jaw 2050 is axially movable within a second relief area or left relief area 1840 formed in the anvil mounting portion 1820. Thus, while the positive opening feature of the proximal jaw 2040 is applying a first opening movement, or initial opening movement, to the anvil mounting portion 1820, the positive opening feature of distal claw 2050 is not applying any significant opening movement anvil 1810. Additional proximal movement of the segment of the distal closing tube 2030 will result in the contact of the positive opening feature of the distal claw 2050 with an opening flap of the left anvil 1842 and the positive opening feature of the proximal claw 2040 disengaging from the opening cam surface of claw 1826. In this way, the positive opening feature of proximal claw 2040 disengaged from the anvil mounting portion 1820 and no longer applies any additional opening movement to it, while the opening feature distal claw positive 2050 is applying a second claw opening movement to the anvil mounting portion 1820 to articulate the 1810 to a fully open position, shown in Figures 68, 71, 76 and 77.

[0223] Figure 78 illustrates the process of opening the claw or stool used by the set of interchangeable tools 1000 in graphic form. As can be seen in this Figure, the left or vertical geometric axis of the graph represents the degree of opening of the claw from about 0º to about 22º ("anvil opening angle") and the bottom or horizontal axis represents the axial displacement proximal approach to the segment of the distal closing tube 2030 from a position where the anvil is completely closed to a position where the anvil is completely open.

As indicated above, the "anvil opening angle" or "claw opening angle" can represent the angle between the cartridge platform surface or tissue contact surface over the surgical fastener cartridge or the "first claw" and the fastener-forming surface or fabric contact surface on the anvil or the "second claw". When the anvil is completely closed, the anvil opening angle can be, for example, approximately 0º.

In the illustrated arrangement, the 2030 distal closing tube segment can move proximally from a first position (1850 in the graph) which corresponds to the completely closed position at a distance of, for example, about 0.040 inches until a first intermediate position (1852 in the graph) before the positive proximal jaw opening feature 2040 begins to apply a first jaw opening movement to the anvil 1810. As the distal closing tube segment 2030 continues to move proximally from from the first intermediate position 1852 to a second intermediate position (1854 in the graph), an additional proximal distance of, for example, about 0.040 inches to about 0.120 inches, the 2040 proximal claw positive opening feature moves the anvil 1810 through an anvil opening angle from 0º to about 10º.

Although the segment of the distal closing tube 2030 continues to move proximally from the second intermediate position 1854 to a third intermediate position (1856 in the graph) an additional proximal distance (from about 0.120 inch to about 0.140 inch), the anvil remains at an anvil opening angle of about

10th. With the additional proximal movement of the 2030 distal closing tube segment from the third intermediate position 1856 to a fourth intermediate position (1858 in the graph) from a proximal distance (from about 0.140 inch to about 0.240 inch), the positive distal claw opening feature 2050 begins to apply a second claw opening motion to the anvil 1810. As the 2030 distal closing tube segment continues to move proximally from third intermediate position 1856 to fourth intermediate position (1858 in the graph), an additional proximal distance (from, for example, about 0.140 inch to about 0.240 inch), the positive distal claw opening feature 2050 moves the anvil 1810 relative to the elongated channel 1602 so that the angle of anvil opening increases, for example, from 10º to about 22º. Although the segment of the distal closing tube 2030 continues to move proximally from the intermediate fourth position 1858 to a final proximal position (1860 in the graph) an additional proximal distance (from about 0.240 inch to about 0.260 inch, for example) , the anvil 1810 remains in a fully open position with an anvil opening angle of approximately 22 °.

[0224] The process of closing the illustrated example of the interchangeable tool set 1000 can be understood from the reference to Figures 67 to 69 and 70 to 72, as well as Figure 78. Figures 68 and 71 illustrate anvil 1810 in its fully open position. As can be seen in these figures, the proximal claw positive opening feature 2040 is out of contact with the anvil mounting portion 1820 and the distal claw positive opening feature 2050 is in contact with the left anvil open flap.

1842. When the anvil closing process is initiated, the closing drive system is actuated to move the 2030 distal closing tube segment in the distal DD direction. As the segment of the distal closing tube moves from the final proximal position 1860 to the fourth intermediate position 1858 (Figure 78), the beaker 1810 remains in its fully open position.

Thus, once the closing process is initiated, in at least one example, the distal closing tube segment 2030 can move distally at a first or predetermined initial axial closing distance before anvil 1810 start moving.

In other words, the distal closing tube segment can move the first predetermined axial closing distance before any closing movement is applied to the 1810 anvil. In at least one example, the first predetermined closing distance or distance it can be approximately 0.020 inch.

As the distal closing tube segment 2030 continues to move distally across an intermediate axial closing distance, the distal end 2035 of the distal closing tube segment 2030 begins to come into contact with the anvil cam surface 1821 on the anvil mounting portion 1820 (Figures 67 and 70) until the inner cam surface 2036 in the distal closing pipe segment 2030 begins to come into contact with the anvil cam surface 1821. According to the internal cam surface 2036 moves above the anvil cam surface 1821, anvil 1810 is pivoted to the fully closed position.

The anvil cam surface 1821 and the internal cam surface 2036 can be configured to allow additional distal displacement of the segment of the distal closing tube 2030, for example, from the first point or intermediate position 1852 to the first position 1850 (Figure 78). Thus, in at least one example, the distal closing tube segment 2030 can move distally at a predetermined axial closing distance during

during the closing process after the anvil 1810 reaches its completely closed position. In at least one example, the final predetermined axial closing distance can be approximately 0.040 inches.

[0225] In those surgical stapling devices that employ a firing member assembly comprising a firing member that has a tissue cutting surface, it may be desirable that the firing system and the end actuator portions are configured to prevent inadvertent advancement of the firing member, unless an uns worn staple cartridge is properly supported on the end actuator. If, for example, no staple cartridge is present and the firing member is advanced distally through the end actuator, the tissue would be cut, but not stapled. Similarly, if a staple cartridge used (that is, a staple cartridge in which at least some staples have already been fired) is present on the end actuator and the firing member is advanced, the fabric would be cut , but it may not be fully stapled if it were stapled. It will be recognized that such occurrences could lead to undesirable catastrophic results during the surgical procedure.

TRUMENTS WITH LOCKOUT ARRANGEMENTS FOR PREVENTING FIRING SYSTEM ACTUATION UNLESS AN UNSPENT STAPLE CARTRIDGE IS PRESENT reveal various trigger member stop arrangements. Each of these references is hereby incorporated by reference, in its entirety.

[0226] Referring to Figures 60A and 60 |, a surgical end actuator 9010 is shown which comprises a portion of a 9000 surgical tool set comprising a first 9020 jaw and a second 9120 jaw. In the illustrated arrangement, for example For example, the first claw 9020 comprises an elongated channel 9022 which is configured to operationally and removably support a 9600 surgical staple cartridge within it. The elongated channel 9022 is attached to an elongated drive shaft assembly 9300 of the surgical tool set. In the arrangement shown in Figures 60C and 60D, for example, the elongated channel 9022 is pivotally coupled to a central column assembly 9310 of the elongated drive shaft assembly 9300 to perform the selective articulation with respect to it. Refer to Figures 60D, 60E, 60H and 601I. The 9300 elongated drive shaft assembly can define a geometric axis of the SA drive shaft. The second claw 9120 comprises an anvil 9122 which is movably supported on the elongated channel 9022 and which is movable between the open and closed positions by the closing system 9400. The anvil 9122 includes an anvil body 9124 and an assembly portion of anvil 9126 which is pivotally supported for pivoting displacement with respect to the proximal end 9024 of the elongated channel 9022. The closing system 9400 may include, for example, a segment of axially movable distal closing tube 9410 that is configured to engage a cam surface 9128 on the anvil mounting portion 9126 when the segment of the distal closing tube 9410 advances axially in the distal direction DD. The segment of the distal closure tube 9410 can also be configured to apply opening movements to the anvil mounting portion 9126 when the segment of the distal closure tube 9410 moves in the proximal direction PD. See Figures 60C and 60D.

[0227] The surgical tool set 9000 additionally includes a 9500 firing system which, in the illustrated arrangement, comprises a 9510 firing member set which is configured to receive firing movements from a firing control system. paro supported in a housing of a hand control system or a robotic control system, for example. In the illustrated embodiment, a shape of the firing member assembly 9510 comprises a first firing member element 9520 consisting of a firing member body 9522 that supports a tissue or blade 9524 cutting surface thereon. The body of the firing element 9522 is coupled to a firing bar or cutter bar 9530 that interfaces operationally with the corresponding portions of the 9500 firing system to receive the firing movements of the firing control system. The firing member body 9522 may include a second claw or anvil engaging features 9526 which may comprise laterally extending flap features configured to be received within the corresponding second claw passages or slits 9125 in the body. anvil 9124. In addition, the firing member body 9522 may additionally include the first jaw or channel engaging features or a base 9528 that is configured to be received in the corresponding first jaw passages, slots or openings 9023 in the elongated channel

9022.

[0228] The 2800 staple cartridge comprises a 9602 cartridge body. See Figures 60H and 60I. The cartridge body 9602 includes a proximal end 9604, a distal end (not shown) and a platform 9606 extending between the proximal end and the distal end. In use, the staple cartridge 9600 is positioned on a first side of the fabric to be stapled and anvil 9122 is positioned on a second side of the fabric. The anvil 9122 is moved towards the staple cartridge 9600 to compress and secure the fabric against the 9606 platform. Thereafter, the staples or fasteners removably stored in the 9602 cartridge body can be implanted in the fabric. The 9602 cartridge body includes staple or fastener cavities (not shown) defined therein, the staples or fasteners (not shown) are removably stored in the staple cavities. The staple cavities can be arranged in longitudinal rows. In one arrangement, for example, 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. The longitudinal slot is configured to axially receive the first firing member element 9520 through it. Other arrangements of staple / fastener cavities and staples or fasteners may be possible.

[0229] Clamps or fasteners are supported by clamp actuators (not shown) that are movably supported on the 9602 cartridge body. The actuators are movable between a first position, or an unchained position, and a second position, or fired position, to eject the clamps or fasteners from the cavities. The drivers are retained in the 9602 cartridge body by a retainer (not shown) that extends around the bottom of the 9602 cartridge body and includes resilient members configured to secure the cartridge body and secure the retainer to the cartridge body.

The triggers are movable between their non-triggered positions and their triggered positions by a 9610 slide. The 9610 slide is movable between a proximal or "non-triggered" position adjacent to the proximal end 9604 and a distal or "triggered" position adjacent to the distal end ( after firing). As can be seen in Figure 60G, the 9610 slider comprises a plurality of 9620 cam or ramp surfaces that are configured to slide under the drivers and lift them, and the clamps or fasteners supported on it, towards the anvil .

A "not fired", "not worn", "free" or "new" 9600 cartridge means, in the present invention, that the 9600 staple cartridge has all of its staples or fasteners in their "ready to be" positions fired ". When in this position, the 9610 slide assembly is in its home or "not fired" position. The new staple cartridge 9600 is seated within the elongated channel 9022 and can be retained there by snap-on features on the 9602 cartridge body, which are configured to engage corresponding portions of the elongated channel 9022 by retention. Figures 60G and 60H illustrate a portion of the surgical end actuator 9010 with a new or unloaded surgical staple cartridge 9600 seated there.

As can be seen in Figures 60G and 60H, slider 9610 is in the non-triggered position.

To prevent the 9500 firing system from being activated and, more precisely, to prevent the first element of the 9520 firing member from being driven distally through the 9010 surgical end actuator, unless a new surgical staple cartridge or not triggered 9600 has been properly seated inside the elongated channel 9022, the illustrated surgical tool set 9000 uses a trigger member locking

9700.

[0230] Now with reference to Figures 60E and 60F, in one form, the locking member of the firing member 9700 comprises a second firing member element or rocking element 9710 comprising a latching portion of the 9720 slider. illustrated position, the second element of the firing member 9710 is pivotally coupled to the body of the firing member 9522 by a clamping joint 9713 in the form of, for example, a 9714 pivot element or elements which are received from articulated manner in the corresponding pivot holes 9523 provided in the body of the firing member 9522 to perform pivoting displacement with respect to it around a pivot geometry axis PA that is transverse to the geometry axis of the drive axis SA. This arrangement facilitates the pivoting displacement of the second element of the firing member 9710 in relation to the body of the firing member 9522 between a locked position (Figure 60E) and an unlocked position (Figure 60F). In the illustrated example, the body of the firing member 9522 comprises a distal surface 9525 which is approximately perpendicular to the channel engagement features 9528 and a locking surface 9527 which is angled with respect to the distal surface 9525. In addition, one or more ramps support elements 9529 are formed in the body of the firing member 9522 which serve to define the corresponding landing surfaces 9531 to receive the second element of the firing member 9710 when in the locked configuration. See Figure 60E.

[0231] As can be seen in Figure 60F, when the second element of the firing member 9710 is in the unlocked position, a space, usually indicated as 9724, is provided between a proximal surface 9722 of the second member of the firing member. firing 9710 and the distal surface 9525 of the firing member 9522. Thus, when in the unlocked position, the proximal surface 9722 of the second element of firing member 9710 is not in contact with the distal surface 9525 of the firing member body. firing 9522. Now referring to Figures 60A to 60D, the second element of firing member 9710 additionally comprises at least one locking-engaging portion 9730 which includes an angled locking end 9732 which is configured to engage with a locking notch. corresponding element 9026 which is formed in the elongated channel 9022 when the second element of the firing member 9710 is in the locked position. In one embodiment, for example, the second element of the firing member 9710 includes two locking-engaging portions

9730. As can also be seen in Figures 60A to 60D, a locking spring or bias member 9740 is mounted at the proximal end 9024 of the elongated channel 9022 and includes two spring arms 9742 that individually correspond to a portion of locking-coupling 9730. The spring arms 9742 serve to propel the second element of the firing member 9710 to the locked position, as shown in Figures 60B to 60D.

[0232] Now with reference to Figures 60G to 60l, the slide 9610 comprises an unlocking portion 9630 that is configured to engage the engaging portion of slide 9720 on the second element of trigger member 9710 when slide 9610 is in position not fired. This arrangement serves to articulate the second element of the firing member 9710 to the unlocked position. When in the unlocked position, the end of the angled lock 9732 of each locking-engaging portion 9730 is pivoted out of the corresponding locking notch 9026 in the elongated channel 9022 so that the firing member assembly 9510 can be fired or advanced distally through staple cartridge. If the staple cartridge that was loaded in the elongated channel 9022 was previously fired or even partially fired, the slide 9610 will not be in the non-fired position, in order to articulate the element segment of the firing member 9710 to the unlocked position. In such a case, the physician will not be able to advance distally or fire the 9510 firing member assembly. When in the unlocked position, actuation of the 9500 firing system will result in the 9510 firing member assembly being dislocated. indicated above, when the firing member 9510 is activated distally, the second firing member 9710 is in contact with the firing member 9522 body through the pivot elements

9714. However, when the second element of the firing member 9710 is rotated to the locked position (Figure 60E), a portion of the proximal surface 9722 is in contiguous contact with the angled locking surface 9527 on the body of the firing member 9522 In addition, as can be seen more particularly in Figures 60E and 60F, pivot hole 9523 in the body of the firing member 9522 is dimensioned in relation to the corresponding pivot member 9714 to provide a clearance C between them so that the load is transferred through the second member of the firing member directly to the body of the firing member 9522 and not through the pivot members 9714. As can be seen in Figure 60E, the angled locking surface 9527 facilitates the pivoting movement of the engagement portion of the 9720 slider to the locked position. When the second element of the trigger member 9720 is in the locked position, if the physician inadvertently applies an FM trigger movement to the assembly of the trigger element 9510 in the distal direction DD, the engagement between the second element of the trigger member 9720 and lock notch 9026 on elongated channel 9022 will prevent distal advance of trigger member 9510 and cause a resulting unlocking load force UL to be applied to the second element of trigger member 9720. That load force of UL unlocking will be applied to the angled locking surface 9527 on the body of firing member 9522 and will not be applied to pivot elements 9714. This arrangement avoids the loading or tension of pivot elements 9714 in case the doctor inadvertently tries advance the triggering element set 9510 to the locked position. In this way, this configuration can prevent the 9714 pivot elements from being cut during such an attempt to advance the 9510 firing member assembly.

[0233] In this way, the aforementioned firing member assembly 9510 and firing member locking assembly 9700 can provide several advantages. For example, as discussed above, the distal surface 9525 of the body of the firing member 9522 carries the load during firing and prevents the transfer of that charge to the pivot elements that secure the second firing member 9710 to the first firing member. shooting member

9520. When in the locked state or locked position, the load is carried by the ends of the angled lock 9732 over the locking hitch 9730 portions. This arrangement also avoids the need for the 9510 firing member assembly, or more precisely. the first element of the firing member 9520 moves vertically, which can inadvertently cause misalignment with the anvil and the elongated channel when moved to an unlocked state for firing. In addition, due to the fact that the first element of the firing member 9520 does not move vertically, the anvil engaging features, as well as the channel engaging features, can be advantageously shaped and designed to obtain the desirable engagement. with the anvil and the channel during firing. The design and shape of the firing member body can also provide a large surface area for attachment to the cutter bar, for example, by welding. For example, the distal end of the cutter bar can be attached to the body of the firing member by an edge weld and a laser weld on both sides to interconnect the laminates, forming the cutter bar at the distal end. This weld configuration can be more compact longitudinally than previous weld configurations, and can result in a longer joint length. Other advantages can also be enjoyed from the previous firing member and the locking system arrangements.

[0234] Many of the surgical instrument systems described here are driven by an electric motor; however, the surgical instrument systems described here can be induced in any suitable manner. In several examples, the surgical instrument systems described herein can be induced, for example, by a manually operated trigger. In certain cases, the motors disclosed in this document may comprise a portion or portions of a robotically controlled system. In addition, any of the end actuators and / or tool sets shown in the present invention can be used with a robotic surgical instrument system. US Patent Application Serial No. 13 / 118,241, entitled

SURGICAL STAPLING INSTRUMENTS WITH ROTATABLE STAPLE DEPLOYMENT ARRANGEMENTS, now US Patent No. 9,072,535, for example, reveals several examples of a robotic surgical instrument system in more detail.

[0235] The surgical instrument systems described here have been described in connection with the implantation and deformation of the clamps; however, the modalities described in the present invention are not | limited in this way. Several modalities are foreseen, which implant fasteners in addition to staples, such as claws or tacks, for example. In addition, several modalities are contemplated, which use any suitable means to seal the fabric. For example, an end actuator, according to various modalities, may comprise electrodes configured to heat and seal the tissue. Likewise, for example, an end actuator according to certain modalities, can apply vibrational energy to seal the tissue. Examples
