However, surgical instruments can be used in many orientations and positions, and these terms are not intended to be limiting and / or absolute.

[0151] 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.

[0152] The surgical stapling system can comprise a drive shaft and an end actuator that extends from the drive shaft. The end actuator comprises a first jaw and a second jaw. The first jaw comprises a staple cartridge. The staple cartridge is insertable into, and removable from, the first 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 pivot axis that extends through the joint. Other modalities are foreseen that do not include an articulation joint.

[0153] The staple cartridge comprises a cartridge body. The cartridge body includes a proximal end, a distal end, and a platform that extends between the proximal end and the distal end. In use, the staple cartridge is positioned on 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.

[0154] Staples are supported by staple actuators on the cartridge body. The actuators are movable between a first position, or non-triggered position, and a second position, or triggered position, to eject the clamps from the clamp cavities. The actuators are retained in the cartridge body by a retainer that extends around the bottom of the cartridge body and includes resilient members configured to secure the cartridge body and retain the retainer in the cartridge body. The actuators are 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.

[0155] In addition to the above, the slider is moved distally by a firing member. The firing member is configured to contact the slide and push the slide towards the distal end. The longitudinal slot defined in the cartridge body is configured to receive the firing member. The anvil also includes a slot configured to receive the firing member. The firing member 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.

[0156] 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 Figure 1, an example of surgical system 10 includes four interchangeable surgical tool sets 1000, 3000, 5000 and 7000 which are adapted for interchangeable use with a 500 handle set. Each interchangeable surgical tool set 1000 , 3000, 5000 and 7000 can be designed for use in connection with the performance of one or more specific surgical procedures. In another 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.

[0157] Figure 2 illustrates the fixation of the surgical tool set

interchangeable logic 1000 to the handle set 500. It will be understood that any of the other interchangeable tool sets 3000, 5000 and 7000 can be coupled to the handle set 500 in a similar way. 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 cable assembly 500 may comprise a cable compartment 502 that includes a pistol grip portion 504 that can be held and handled by the physician. As will be briefly discussed below, the handle set 500 operatively supports a plurality of drive systems 510, 530, which are configured to generate and apply various control movements to the corresponding portions of the interchangeable surgical tool set 1000 , 3000, 5000 and / or 7000 that is operationally attached to it.

[0158] As seen in Figure 2, the handle assembly 500 may also include a handle structure 506 that operationally supports the plurality of drive systems. For example, the 506 grip structure can operationally support a "first" drive system or closing drive system, generally referred to as 510, which can be used to apply closing and opening movements to the interchangeable surgical tool set 1000, 3000, 5000 and 7000 that is fixed or operationally attached to the handle set

500. In at least one way, the locking drive system 510 can include an actuator in the form of a locking trigger 512, pivotally supported by the 506 handle structure. This arrangement allows the closing trigger 512 is handled by a physician, so that when the physician holds the pistol grip portion 504 of the handle assembly 500, the closing trigger 512 can be easily rotated from an initial or "not actuated" position "to an" acted "position and, more particularly, to a fully 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 joint assembly 514 includes a cross fixation pin 516 that facilitates attachment to a corresponding drive system in the set of surgical tools.

In use, to actuate the closing drive system 510, the doctor presses the closing trigger 512 towards the pistol grip portion 504. As described in more detail in US Patent Application serial number 14 / 226,142 , entitled SURGICAL INSTRUMENT COM- PRISING A SENSOR SYSTEM, now US Patent Application Publication No. 2015/0272575 which is hereby incorporated by reference in its entirety, the 510 closing drive system is configured to lock the trigger closing button 512 in the fully pressed or fully actuated position when the doctor fully presses the closing button 512 to obtain the complete closing stroke.

When the clinician wishes to unlock the closing trigger 512 to allow the closing trigger 512 to be propelled to the unacted position, the physician activates a set of the closing release button 518 that allows the closing trigger to return to its position. unacted position.

The 518 lock release button set can also be configured to interact with various sensors that communicate with a microprocessor

560 on the grip handle 500 to track the position of the closing trigger 512. Further discussion regarding the configuration and operation of the lock release button assembly 518 can be found in US Patent Application Publication No. 2015 / 0272575.

[0159] In at least one form, the handle assembly 500 and the handle structure 506 can operationally support another drive system called in the present invention a trigger drive system 530, which is configured to apply trigger movements to the portions corresponding to the interchangeable surgical tool set that is attached to it. As described in detail in US Patent Application Publication No. 0272575, the 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, the 522 power source can be replaceable and / or rechargeable.

[0160] The 505 electric motor is configured to drive a longitudinally movable drive member axially in the distal and proximal directions depending on the polarity of the voltage applied to the motor.

For example, when the motor is started in a rotating direction, the longitudinally movable drive member will be 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 that they are configured to detect the position of the drive member and / or the direction in which the drive member is being moved.

The activation of motor 505 can be controlled by a trigger trigger 532 (Figure 1) pivotally held in the handle assembly 500. The trigger trigger 532 can be rotated between an unacted position and an acted position.

The trigger trigger 532 can be moved to the unacted position by means of a spring or other propensity arrangement so that when the doctor releases the trigger trigger 532, the trigger trigger 532 can be turned or otherwise, returned to the unactivated position by means of the spring or the bias arrangement.

In at least one way, trigger trigger 532 can be positioned "far" from closing trigger 512, as discussed above.

As discussed in US Patent Application Publication 2015/0272575, the handle assembly 500 can be equipped with a trigger trigger safety button to prevent inadvertent triggering of the trigger trigger 532. When the trigger trigger closing 512 is in the unacted position, the safety button is contained in the grip set 500, where the doctor cannot readily access it and move it between a safety position, which prevents the trigger trigger 532 from acting, and a firing position at which trigger trigger 532 can be fired. When the physician presses the closing trigger 512, the safety button and trigger trigger 532 pivot downward, where they can then be manipulated by the physician.

[0161] In at least one form, the longitudinally movable drive member may have a toothed rack formed in it for engagement with a corresponding drive gear arrangement that interfaces with the motor. Additional details regarding those resources can be found in US Patent Application Publication 2015/0272575. In at least one form, the handle assembly 500 also includes a manually actionable retraction assembly that is configured to enable the physician to manually retract the longitudinally movable driving member if the 505 motor is disabled. The rescue kit may include a lever or rescue cable assembly that is stored inside the cable assembly 500 under a removable door

550. See Figure 2. The lever can be configured to be manually articulated in ratchet engagement with the teeth on the drive member. In this way, the physician can manually retract drive member 540 using the retract handle assembly to engage drive member 540 in the proximal "PD" direction. US Patent No. 8,608,045, entitled POWERED SURGI-CAL CUTTING AND STAPLING APPARATUS WITH MANUALLY RE-TRACTABLE 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 they can also be used with any of the various interchangeable surgical tool sets disclosed in the present invention.

[0162] Turning now to Figures 3 and 4, the interchangeable surgical tool set 1000 includes a surgical end actuator 1500 comprising a first claw 1600 and a second claw 1800. In one arrangement, the first claw 1600 comprises an elongated channel 1602 which is configured to operationally support a 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.

[0163] As can be seen further in Figures 4 and 7-9, the interchangeable surgical tool set 1000 includes a tool frame assembly 1200 comprising a tool chassis 1210 that operationally supports a nozzle assembly 1240 in it . In one form, the nose assembly 1240 is comprised of nozzle portions 1242, 1244 as well as an actuator wheel portion 1246 that is configured to be coupled to the assembled nozzle portions 1242, 1244 by pressure fittings, pins and / or screws, for example. The Interchangeable Surgical Tool Set 1000 includes a proximal closure set 1900 that is operationally coupled to a distal closure set 2000 that is used to close and / or open the anvil 1810 of the surgical end actuator 1500 as will be discussed further in details below. In addition, the interchangeable surgical tool set 1000 includes a central column set 1250 that operationally supports the proximal closing set 1900 and is coupled to the surgical end actuator 1500. In various circumstances, to facilitate assembly, the central column assembly 1250 can be manufactured from an upper central column segment 1251 and a lower central column segment 1252 which are interconnected together by pressure fitting, adhesives and / or weld features, for example. In assembled form, the center column assembly 1250 includes a proximal end 1253 that is pivotally supported on the tool frame 1210. In one arrangement, for example, the proximal end 1253 of the center column assembly 1250 is attached to a bearing. center column (not shown) that is configured to be supported within the 1210 tool chassis. This arrangement facilitates the swivel attachment of the dorsal assembly 1250 to the 1210 tool chassis, so that the dorsal assembly 1250 can be selectively rotated around a geometric axis of the drive axis SA; in relation to the tool chassis 1210. In particular, in at least one arrangement, the proximal end 1253 of the center column assembly 1250 includes an upper pin location 1254 (Figures 4, 5,7, 8 and 10) and a bottom pin locations that are individually configured to receive a corresponding nozzle pin 1245 extending inwardly from each of the nozzle portions 1242, 1244, for example. This arrangement facilitates the rotation of the central column assembly 1250 around the geometric axis of the drive shaft SA: by rotating the wheel portion of the actuator 1246 of the nozzle assembly 1240.

[0164] As can be seen in Figures 4 and 5, the central column assembly 1250 additionally includes a segment of the drive shaft of the intermediate dorsum 1256 that has a diameter that is smaller than the diameter of the proximal end 1253 of the assembly center column 1250. The center axis 1256 drive axis segment of the upper center column 1251 segment ends in an upper pin assembly feature 1260 and the center axis column driving axis segment 1260 lower center 1252 ends in a lower pin assembly feature 1270. As can be seen in Figure 6, for example, the upper pin assembly feature 1260 is formed with a pin slot 1262 in it that is adapted to support an upper mounting connection 1264 on it. Similarly, the lower pin assembly feature 1270 is formed with a pin slot 1272 in it which is adapted to support a lower assembly link 1274 in a passable manner. The upper mounting link 1264 includes a pivot socket 1266 inside 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 in a channel cover or anvil retainer 1630 which is attached to a proximal end portion 1610 of the elongated channel 1602. The mono connection - lower dimension 1274 includes a 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 hole 1611, it is displaced 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 pivot axis AA: around which the surgical end actuator 1500 can pivot in relation to the geometric axis of the drive shaft SA :. Although the articulation axis AA: is transversal to the geometric axis of the drive axis SA, the articulation axis AA; it is laterally displaced from it and does not cross the geometric axis of the drive axis SA :.

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

[0166] The 1500 surgical end actuator is selectively articulated around the AA pivot axis: by the pivot system

1300. In one form, the hinge system 1300 includes the proximal hinge actuator 1310 which is pivotally coupled to a hinge link 1320. As can be seen in Figure 6, an offset clamping pin 1314 is formed at a proximal end 1313 of the proximal articulation driver 1310. A pivot hole 1316 is formed in the displaced fixing pin 1314 and is configured to pivotively receive a proximal link pin 1326 formed at the proximal end 1325 of the articulation link 1320. A distal end 1322 of the hinge link 1320 includes a pivot hole 1324 which is configured to pivotally receive within it a channel pin 1618 formed at the proximal end portion 1610 of the elongated channel 1602. In this way, the axial movement of the proximal articulation actuator 1310 will apply articulation movements to the elongated channel 1602 to articulate the surgical end actuator 1500 around the axis of articulation AA: in relation to the central column assembly 1250.

[0167] The movement of the anvil 1810 in relation to the elongated channel 1602 is effected by the axial movement of the 1900 proximal closing system and the distal closing system.

2000. Now with reference to Figures 4 and 7, 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 distal portion 1930 has a diameter that is smaller than the diameter of the proximal closing tube portion 1920. The proximal end 1922 of the proximal closing tube portion 1920 is pivotally supported on a reciprocating closing element 1940 which is slidably supported within the 1210 tool frame, so that the reciprocating closing element 1940 can move axially with respect to the tool chassis 1210. In one form, the reciprocating closing element 1940 includes a pair of proximally protruding 1942 hooks that are configured to be fixed to the lock pin. fixation 516 which is attached to the closing hinge assembly 514 of the handle assembly 500. A proximal end 1922 of the pro-closing tube portion ximal 1920 is rotatably coupled to the reciprocating 1940 closing element. For example, a 1944 U-shaped connector is inserted into a 1924 annular slot in the 1920 proximal closing tube portion and is retained within the 1946 vertical slots in the 1940 closing reciprocating element. This arrangement serves to fix the 1900 closing member to the 1940 closing reciprocating member for axial displacement with the same, while allowing the 1900 closing member to rotate in relation to the element. 1940 reciprocating closure around the geometry axis of the drive shaft SA :. A closing spring 1948 (Figures 12-14) extends over the portion of the proximal closing tube 1920 to propose the reciprocating closing element 1940 in the proximal direction PD, which can serve to revolve the closing trigger 512 over the handle set 500 (Figure 2) for the unacted position when the interchangeable surgical tool set 1000 is operationally coupled to the handle set

500.

[0168] Now with reference to Figures 5 and 6, a distal portion 1930 of the proximal closing tube 1910 is attached to the distal closing assembly 2000. The distal closing assembly 2000 includes a hinge connector 2010 that is coupled to a distal closing tube segment 2030. The distal closing tube segment 2030 has a diameter that is larger than the diameter of the distal portion 1930 of the proximal closing tube 1910. The hinge connector 2010 has an end portion that extends proximally 2012 which is adapted to be received on a 1934 connection flange formed at the distal end of the distal portion 1930. The 2010 connector can be retained on the 1934 connection flange by a suitable fastener, adhesive and / or welds, for example. The hinge connector 2010 includes the upper and lower protuberances 2014, 2016 that project distally from a distal end of the hinge connector 2010 that are movably coupled to a closing sleeve of the end actuator or pipe segment distal closure 2030. The distal closure tube segment 2030 includes an upper protrusion 2032 and a lower protrusion 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 on the upper latches 2014, 2032 of the hinge connector 2010 and the segment of the distal closing tube 2030, respectively. Similarly, a lower double pivot link 2064 includes the 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 closure and opening of the shoulder 1810 in relation to the elongated channel 1602.

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

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

2130. Once the end actuator 1500 has been properly oriented, the portion of the intermediate firing drive shaft 2120 can be advanced distally until a proximal side wall of the longitudinal slot 2124 contacts a portion of the 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. A proximal end 2127 of the intermediate firing drive shaft portion 2120 has a fixing pin for the firing drive shaft 2128 formed on it (Figure 8) which is configured to be seated on a coupling base which is on the distal end of the longitudinally movable driving member of the driving system 530 within the handle set 500. This arrangement facilitates the axial movement of the portion of the intermediate firing drive shaft 2120 by means of the actuation system triggering 530.

[0170] In addition to the above, the interchangeable tool set 1000 can include a 2200 gear set, which can be configured to selectively and releasably 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 articulation lock 1400 when the proximal articulation actuator 1310 is not being moved in the proximal or distal direction by the set of shooting member 2110.

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

[0172] Now with reference to Figures 8 and 12 to 14, the locking sleeve

2210 additionally includes a lock member 2218 which is dimensioned to be movably received within a notch 1319 at a proximal end 1318 of the proximal articulation driver

1310. This arrangement allows the 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 on the proximal pivot driver 1310. For example, when the lock sleeve 2210 is in its engaged position, the lock protrusions 2214, 2216 are positioned inside a drive slot 2126 in the portion of the intermediate drive shaft 2120, so that a force distal pushing force and / or a proximal pulling force can be transmitted from the trigger member 2110 assembly to the locking sleeve 2210. Such a pulling or proximal pushing movement is then transmitted from the locking sleeve 2210 to the proximal articulation actuator 1310 in order to articulate the surgical end actuator 1500. In effect, the firing member assembly 2110, the locking sleeve 2210 and the proximal articulation actuator l 1310 will move together when locking sleeve 2210 is in its engaged position. On the other hand, when the locking sleeve 1622 is in its disengaged position, the locking protrusions 2214, 2216 may not be received inside the drive notch 2126 in the portion of the intermediate firing drive shaft 2120 and, as a result , a distal pushing force and / or a proximal pulling force may not be transmitted from the trigger member 2110 assembly to the locking sleeve 2210 (and the proximal articulation actuator 1310).

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

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

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

2224. See Figures 11 and 12. When in this position, the switch cylinder 2220 can provide torsional polarization to the displacement key 2240, which in this way causes the lock sleeve 2210 to rotate to its engaged position with the intermediate firing drive axis 2120. This position also corresponds to the unactivated configuration of the proximal closing assembly 1900. In one arrangement, for example, the actuator pin 2242 is located in the upper portion of the cam opening 1926 in the pipe portion. proximal closing 1920 when the proximal closing assembly 1900 is in an unacted configuration (anvil 1810 is in an open position spaced away from the staple cartridge / surgical clamps 1700). When in this position, the actuation of the intermediate firing drive shaft portion 2120 will result in the axial movement of the 1310 proximal articulation actuator. After the user has articulated the surgical end actuator 1500 to a desired orientation, the user can then actuate the proximal closing set 1900. The actuation of the proximal closing set 1900 will result in the distal displacement of the portion of the proximal closing tube 1920 to finally apply a closing movement to the anvil

1810. This distal displacement of the proximal closing tube portion 1920 will result in the opening of the cam 1926 interacting with the cam surface 2243 on the actuator pin 2242 to thereby cause the displacement switch 2240 to rotate. lock sleeve 2210 in an AD actuation direction. Such rotation of the lock sleeve 2210 will result in the disengagement of the lugs of the lock 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 actuate the portion of the intermediate firing drive shaft 2120 without activating the proximal articulation trigger 1310. Further details regarding the operation of the switching cylinder 2220 and locking sleeve 2210, as well as articulation and alternating firing arrangements that can be used with the various sets of interchangeable surgical tools described here, can be found at

US Patent Application Serial No. 13 / 803,086, entitled ARTICULATA-

BLE SURGICAL INSTRUMENT COMPRISING AN ARTICULATION LOCK, currently US Patent Application Publication No. 2014/0263541; and US Patent Application Serial No. 15 / 019,196, entitled

SURGICAL INSTRUMENT ARTICULATION MECHANISM WITH SLOTTED SECONDARY CONSTRAINT, the disclosures of which are hereby incorporated by reference in the present invention.

[0175] 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 in the locations of pins 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.

[0176] Also as shown in Figures 7 and 12-14, the interchangeable tool set 1000 can comprise a slide ring set 1230 that can be configured to conduct electrical energy to and / or from the surgical end actuator 1500 and / or transmit signals to and / or from the surgical end actuator 1500 back to a microprocessor 560 (Figure 2) on the handle assembly 500 or on the robotic system controller, for example. More details about the 1230 slip ring assembly and associated connectors can be found in US patent application Serial No. 13 / 803,086, currently ARTICULATABLE SURGICAL INSTRUMENT COMPRISING AN ARTICULATION LOCK, currently Publication Order US patent No. 2014/0263541 and US patent application No. Serial 15 / 019,196, filed on February 9, 2016, entitled SURGICAL INSTRUMENT ARTICULATION MECHANISM WITH SLOTTED SECONDARY CONSTRAINT, each of which is incorporated herein by reference in reference their respective totalities, as well as in US Patent Application Serial No. 13 / 800.067 entitled STA-PLE CARTRIDGE TISSUE THICKNESS SENSOR SYSTEM, currently Patent Application Publication Serial No. 2014/0263552, which is incorporated herein by reference in its entirety. As also described in more detail in the abovementioned patent applications that have been incorporated herein, as a reference, the interchangeable surgical tool set 1000 can also comprise at least one sensor that is configured to detect the position - switching cylinder 2220.

[0177] Again with reference to Figure 2, the chassis of tool 1210 includes at least one tapered clamping portion 1212 formed therein, which is adapted to be received inside a corresponding slot 507 formed inside the distal end portion of the handle structure 506 of the handle assembly 500. Several interchangeable surgical tool sets employ a locking system 1220 to removably attach the interchangeable surgical tool set 1000 to the handle structure 506 of the handle assembly 500. In at least one shape, as can be seen in Figure 7, the locking system 1220 includes a locking member or a locking fork 1222 that is movably coupled, for example, to the tool frame 1210 The locking fork 1222 has a U shape with two legs extending outwardly spaced 1223. Each of the legs 1223 has a pivot pin formed on them which is adapted to r received in the corresponding holes formed in the tool frame 1210. Such an arrangement facilitates the pivoting attachment of the locking fork 1222 to the tooling frame 1210. The locking fork 1222 can include two locking pins that project proximally 1224 that are configured for engagement releasable to corresponding holders or locking grooves 509 at the distal end of the grip structure 506 of the grip set 500. See Figure 2. In various forms, the locking fork 1222 is proximally propelled by a spring or bias member 1225. The actuation of the locking fork 1222 can be done by a locking button 1226 which is slidably mounted on a set of the locking actuator 1221 which is mounted on the tool frame 1210. The locking button 1226 can be propelled in a proximal direction in relation 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 grip structure 506. When the locking fork 1222 it is in "retaining engagement" with the distal end of the handle structure 506, the locking pins 1224 are seated with retention within the corresponding locking retainers or grooves 509 at the distal end of the handle structure 506.

[0178] The locking fork 1222 includes at least one locking hook 1227 which is adapted to contact the corresponding locking pin portion 1943 that is formed in the reciprocating closing element 1940. When the reciprocating closing element 1940 is in a non-actuated position, the locking fork 1222 can be pivoted in a distal direction to unlock the interchangeable surgical tool set 1000 from the handle set 500.

When in this position, the lock hooks 1227 do not come into contact with the lock pin portions 1943 in the reciprocating closing element 1940. However, when the reciprocating closing element 1940 moves to an actuated position, the fork lock lock 1222 is prevented from being pivoted to an unlocked position. In other words, if the doctor tried to turn 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 lock rotating distally, the lock hooks 1227 on the lock fork 1222 would contact the lock pin portions 1943 on the reciprocating locking element 1940 and prevent the lock fork 1222 from moving to an unlocked position.

[0179] Still referring to Figure 6, the cutter bar 2130 may comprise a laminated beam structure that includes at least two layers of beam. Such beam layers may comprise, for example, stainless steel bands that are interconnected, for example, by welds and / or pins, for example, at the proximal ends and / or at other locations along the length thereof. In alternative modes, the distal ends of the bands are not connected to allow the laminates or bands to spread out relative to each other when the end actuator is pivoted. Such an arrangement allows the 2130 cutter bar to be sufficiently flexible 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 CLOSURE STROKE REDUCTION ARRANGE-MENTS, which is incorporated herein 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 regarding the operation of the firing drive shaft support set 2300 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 ARRANGEMENTS and in US Patent Application Serial No. 15 / 019,220, entitled SURGICAL INSTRUMENT WITH AR-TICULATING AND AXIALLY TRANSLATABLE END EFFECTOR, which are hereby incorporated by reference in their respective totalities.

[0180] As can also be seen in Figure 6, a firing member or cutting member 2140 is attached to the distal end of the cutting bar 2130. In an exemplary form, firing member 2140 comprises a body portion 2142 that supports a knife or fabric cutting portion 2144. The body portion 2142 projects through an elongated slot 1604 in the elongated channel 1602 and ends at a base member 2146 that extends laterally on each side of the body portion 2142. As the firing member 2140 is driven distally through the surgical clamp / clamp cartridge 1700, the base member 2146 moves within a pass in the elongated channel 1602 which is located under the clamp / clamp cartridge surgical 1700. In one arrangement, the body portion 2142 includes two central flaps that project laterally 2145 that can move above the central passage inside the 1700 surgical clip / clamp cartridge. See Figure 6. The tissue cutting portion 2144 is disposed between a distally projecting top tip portion 2143 and the base member 2146. As can be seen further in Figure 6, the spreading member

paro 2140 can additionally include two laterally extending top flaps, pins or anvil hitch 2147. As firing member 2140 is driven distally, a top portion of body portion 2142 extends through an anvil slit 1814 centrally arranged and anvil engaging features 2147 slide over the corresponding anvil projections 1816 formed in each side of the anvil slit 1814. To facilitate the mounting of the anvil 1810 and the firing element 2140, in one arrangement, the top of the anvil body 1812 has an opening 1817 in it. Once the anvil 1810 is mounted on the elongated channel 1602 and the firing element 2140 is installed, the opening 1817 is covered by an anvil cover 1819 which is fixed to the anvil body 1812 by welds and / or other means of proper fixing.

[0181] Again with reference to Figure 6, the trigger member 2140 is configured to interface operationally with a slide assembly 2150 that is operationally supported within a body 1702 of the staple cartridge / surgical clamps 1700. Slide assembly 2150 is displaceable slidingly 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 within it a plurality of clip drivers that are aligned in rows on each side of a centrally arranged slot 1708. The centrally arranged slot 1708 allows the firing member 2140 to pass through and cut the tissue that is stuck between the anvil 1810 and the staple cartridge / surgical clamps 1700. The actuators are o associated with corresponding staple / fastener pockets 1712 that open across the upper platform surface 1710 of the cartridge body

1702. Each of the clamp actuators supports one or more clamps or surgical clamps on it. The slide assembly 2150 includes a plurality of inclined or wedge-shaped cams 2152 with each cam 2152 corresponding to a particular line of fasteners or drivers located on one side of the slot 1708.

[0182] To fix the interchangeable surgical tool set 1000 to the handle set 500, referred to in Figure 2, the doctor can position the tool frame 1210 of the interchangeable surgical tool set 1000 above or adjacent to the distal end of the handle structure 506 , so that the tapered clamping portions 1212 formed on the tool frame 1210 are aligned with the slot slots 507 in the grip structure 506. The doctor can then move the interchangeable surgical tool set 1000 along of a geometry axis IA installation that is perpendicular to the drive geometry axis SA to seat the tapered fastening portions 1212 in "operational engagement" with the corresponding receiving slots 507 at the distal end of the grip structure 506. When doing that is, the pin for the firing drive shaft 2128 in the portion on the intermediate firing drive shaft 2120 also it will be seated on the fixing bracket 542 on the longitudinally movable drive member on the handle assembly 500 and the portions of the fixing pin 516 on the closing connection 514 will be seated on the corresponding hooks 1942 on the reciprocating closing element 1940. As used in the present invention, the term "operational coupling" in reference to two components means that the two components are coupled together so that, by applying an actuation movement to them, the components perform their action, function and / or desired procedure.

[0183] During a typical surgical procedure, the doctor can insert the surgical end actuator 1500 into the surgical site through a trocar or other opening in the patient to access the target tissue.

In doing so, the physician aligns axially, or at least substantially, aligns the surgical end actuator 1500 in a non-articulated state along the geometric axis of the drive shaft and inserts the surgical end actuator 1500 through the trocar.

Once the surgical end actuator 1500 has passed through the trocar, the physician may need to articulate the end actuator 1500 to advantageously position the end actuator 1500 adjacent to the target tissue.

In addition to the above, the trigger drive system 530 is operated through a limited range of motion to move the hinge actuator 1310 and hinge the end actuator 1500. This hinge occurs before the anvil is closed on the target tissue.

Once the end actuator has reached the desired articulated position, the physician can then activate the closing drive system 510 to close the anvil 1810 on the target tissue.

Such actuation of the closing drive system 510 activates the displacement assembly 2200 and detaches the articulation drive 1310 from the portion of the intermediate firing drive shaft 2120. Thus, once the target tissue has been adapted When captured on the surgical end actuator 1500, the doctor can again activate the trigger drive system 530 to axially advance the trigger member 2140 through the staple cartridge / surgical fasteners 1700 to trigger the staples inward and cut the tissue -target.

Other closing and firing trigger arrangements, such as portable, manual, automated and / or robotic arrangements, for example, can be used to control the axial movement of the closing system components, the articulation system components and / or the trigger system components of the surgical tool set 1000.

[0184] An end actuator 10500 of a surgical instrument 10000 is illustrated in Figures 16 to 16B. The end actuator 10500 comprises a 10600 cartridge gripper (Figure 18), including a staple cartridge 10700 and, in addition, an anvil 10800 configured to deform staples ejected from the staple cartridge 10700. In use, the anvil 10800 can be rotated between an open, unfixed position and a closed and secured position; however, the 10600 cartridge gripper can be rotatable towards the anvil 10800 in other embodiments. The surgical instrument 10000 additionally comprises a drive shaft 10100 where the end actuator 10500 is pivotally connected to the drive shaft 10100 around a pivot joint 10200. In use, the end actuator 10500 is rotating around joint 10200 between a fully articulated right position (Figure 16A), indicated by angle er, and a fully articulated left position (Figure 16B), indicated by angle e. - and / or any suitable position between them. As discussed in greater detail below, the angles er and e. are limited by the design of the 10000 surgical instrument articulation actuator system. In at least one case, the er and e angles. they are limited to approximately 45 degrees from the non-hinged position of the end actuator 10500 (Figure 16).

[0185] Referring to Figure 18, the driving shaft 10100 of the surgical instrument 10000 comprises an outer closing tube that includes an outer housing 10110 that is movable distally to engage the anvil 10800 and move the anvil 10800 towards the cartridge of clamps 10700. The drive shaft 10100 additionally comprises a portion of distal housing 10130 pivotally connected to outer housing 10110 by two connector plates

10120 positioned on opposite sides of the articulation joint 10200. Each connector plate 10120 is connected to the outer housing 10110 in a pivot 10115 and, similarly, to the portion of the distal housing 10130 in a pivot 10125. The connector plates 10120 allow the pipe closing mechanism slips in relation to hinge joint 10200 when end actuator 10500 is in an articulated position and, as a result, anvil 10800 can be opened and closed while end actuator 10500 is in an articulated position lada. In addition to the above, the distal housing 10130 comprises an opening defined there configured to receive a flap that extends from the proximal end of the anvil 10800 - whose side wall is configured to engage the flap and transfer a proximal movement, or opening, from the closing tube to the anvil

10800.

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

[0187] Referring to Figure 19, the drive shaft 11100 of the surgical instrument 11000 comprises an outer closing tube that includes an external housing 11110 that is movable distally to engage the anvil 11800 and move the anvil 11800 towards the cartridge of staples 11700. The drive shaft 11100 additionally comprises a distal housing 11130 rotatably connected to the outer housing 11110 by two connector plates 11120 positioned on opposite sides of the hinge joint 11200. Each connector plate 11120 is connected to the housing external 11110 in a pivot 11115 and, similarly, to the distal housing 11130 in a pivot

11125. Similar to the above, connector plates 11120 allow the closing tube to slide in relation to the hinge joint 11200 when end actuator 11500 is in an articulated position where, as a result, anvil 11800 can be opened and closed while the 11500 end actuator is in an articulated position. In addition to the above, the distal housing 11130 comprises an opening defined there configured to receive a flap extending from the proximal end of the anvil 11800 - the side wall of which is configured to engage the flap and transfer a proximal or opening movement, from the closing tube to the 11800 anvil.

[0188] Again with reference to Figure 18, the surgical instrument 10000 additionally comprises a system of articulation actuator 10300 that includes an actuator of articulation actuator

10310 which extends through an inner opening 10105 defined in the closing tube 10110 of the drive shaft 10100. The hinge actuator actuator 10310 comprises a distal end operatively engaged with the claw of the 10600 cartridge of the end actuator 10500. More specifically, the distal end of the hinge actuator 10310 comprises an opening, or slot, 10320 defined therein, and the 10600 cartridge claw comprises a pin 10620 that extends into the hollow 10320. When the hinge actuator actuator 10310 is pushed away, the end actuator 10500 is driven to the right (Figure 16A) around a fixed geometric axis defined by a pivot 10210 that swivelly connects the 10600 cartridge jaw to a shaft structure actuator 10100. Correspondingly, end actuator 10500 is turned to the left (Figure 16B) around pivot 10210 when the actuator actuated articulation r 10310 is pulled proximally.

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

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

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

[0192] In addition to the above, joint actuator 10310 is configured to torque the first claw 10600 of end actuator 10500 through pin 10620 to rotate end actuator 10500 around joint 10200. In - again with reference to Figure 22, a lateral torque arm defined between the pivot joint 10210 of the articulation joint 10200 and the pin 10620 has a length TAc: when the end actuator 10500 is in its non-articulated position. The length TAc: is measured in an orthogonal direction with respect to a longitudinal geometric axis 10190 that extends through the joint pivot joint 10210. Similarly, the lateral torque arm defined between joint joint 10210 and pin 10620 has a length TAr: when the end actuator 10500 is fully articulated to the right and, similarly, a length TA ': when the end actuator

10500 is fully articulated to the left - both lengths are measured orthogonally in relation to the longitudinal geometric axis 10190. Notably, the lengths TAr: and TAL, and the torque arms they define, are the same, or at least substantially ally equal. In addition, the lengths TAr: and TAL: are shorter than the length of the non-articulated lateral torque arm TAc1. In this way, the largest torque arm, or mechanical advantage, of the 10300 articulation system exists when the end actuator 10500 is in its non-articulated position.

[0193] In at least one case, the length of the arm TAc: is approximately 0.180 ", the length of the arm TAr: is approximately 0.130" and the length of the arm TAL: is approximately 0.130 ", for example.

[0194] In addition to the above, the articulation actuator 11310 of the surgical instrument 11000 is configured to torque the first jaw 11600 of the end actuator 11500 through pin 11620 to rotate the end actuator 11500 around the joint. pivot 11200. Referring to Figures 23, 28 and 30, a lateral torque arm (LTA) defined between pivot joint 11210 of pivot joint 11200 and pin 11620 is defined by a length TAc2 when the end actuator 11500 is in its non-articulated position. The length TAc2 is measured in an orthogonal direction in relation to a longitudinal axis 11190 that extends through the joint pivot joint 11210. Notably, the longitudinal axis 11190 is offset and parallel to the center line of the drive shaft 11100, as discussed in more detail below in connection with Figure 25. Similar to the above, the lateral torque arm defined between joint joint 11210 and pin 11620 is defined by a length TAr2 when the end actuator 11500 is fully articulated to the right (Figure 30A) and, similarly, a TAL2 length when the end actuator 11500 is completely articulated to the left (Figure 30B) - both lengths are measured orthogonally to each other to the longitudinal geometric axis 11190. Notably, the length TAr2 is greater than the length of the non-articulated lateral torque arm TAc: and the length TA,> is more cu the length of the non-articulated lateral torque arm TAc1. In addition, the TAr lengths? and TAr2, and the torque arms they define, are not the same. Instead, the length of the torque arm articulated to the right TAr2 is considerably longer than the length of the torque arm articulated to the left TAr> 2. In fact, the length of the torque arm articulated to the right TAr2 and the length of the torque arm articulated to the left TA,>? extend in different directions. Such an arrangement provides a greater pushing torque arm compared to a smaller pulling torque arm. In several cases, as a result, the retract pull force applied by the 11310 hinge actuator to link the end actuator 11500 to the left (Figure 30B) may be, or may need to be, greater than the force distal thrust to articulate end actuator 11500 to the right (Figures 29 and 30A). Advantageously, the 11310 articulating actuator can accommodate such greater pulling force as the 11310 articulating actuator is not subject to warping failure when being pulled.

[0195] In at least one case, the length of the arm TAc> is approximately 0.149 ", the length TAr? Is approximately 0.154" and the length of the arm TAL? is approximately 0.015 ", for example.

[0196] In addition to the above, surgical instrument 11000 is configured and arranged to provide a high torque to the 11500 end actuator while, at the same time, providing a wide range of articulation, or sweeping, in response to a short articulation stroke. Namely, several design reasons for these relationships can be established and used to design the 11000 surgical instrument. For example, a first reason comprises the length of the torque arm fully articulated to the right (TA) divided by the length of the stroke complete articulation (SL) of the 11310 articulation actuator. The value of this first ratio is dimensionless. In at least one case, the torque arm fully articulated to the right (TA) measures 0.154 "and the length of the complete articulation stroke (SL) measures 0.275", resulting in a ratio value of 0.56, for example. Higher ratio values for the first ratio indicate more efficient articulation systems. In many cases, the value for the first reason is less than 1.0, but it can be greater than 1.0. In at least one case, the fully articulated torque arm to the right (TA) measures 2.79 cm and the length of the complete articulation stroke (SL) measures 11.43 mm, resulting in a ratio value of 0.24 , for example.

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

(TA) is 1.41 mm, resulting in a ratio value of 0.12 for a stroke length (SL) of 11.43 mm, for example.

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

[0199] A third reason comprises the sum of the length of the torque arm fully articulated to the right (TA) and the length of the sweeping arc (ALS) of the drive pin 11620 divided by the length of the complete articulation stroke (SL ). The value of this third reason is dimensionless. In at least one case, the length of the torque arm fully articulated to the right (TA) is 0.154 ", the length of the sweeping arc (ALS) of the drive pin 11620 is 0.387" and the length of the articulation stroke complete (SL) is 0.275 ", resulting in a ratio value of 1.97, for example. In at least one case, the torque arm length fully articulated to the right (TA) is 2.79 mm, the length The scanning arm (ALS) of the 11620 drive pin is 12.94 mm and the length of the complete articulation stroke (SL) is 11.43 mm, resulting in a ratio value of 1.38, for example. Larger ratios for the third ratio indicate more efficient articulation systems In many cases, the value for the third ratio is greater than 1.0, such as between 1.0 and 3.0, for example. In this case, the third ratio value is approximately 2.0 or greater than 2.0, for example.

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

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

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

[0203] As discussed above, the end actuator 11500 is pivotally mounted to the drive shaft 11100 around a fixed pivot 11210 of the articulation joint 11200. Now with reference to Figures 24 and 25, the drive shaft 11100 comprises 11220 distal mounting tabs that extend from and are fixedly mounted to the structure, or central column, of the drive shaft

11100. A first distal mounting flap 11220 is mounted on the first claw 11600, which comprises a lower frame portion, and a second distal mounting flap 11220 is mounted on a upper structure portion 11230. The interconnection between the flaps of assembly 11220 and the first claw 11600 and the upper frame portion 11230 define the fixed pivot 11210. As also discussed above, the pivot of the fixed axis 11210 is laterally displaced with respect to a central longitudinal geometric axis LA of the drive axis 11100 for an OD travel distance. In at least one case, the fixed axis pivot 11210 is laterally displaced by approximately 0.036 ", for example. In addition, with reference to Figures 28 to 30B, pin 11620 is longitudinally displaced in relation to the fixed pivot 11210 which creates an arm of longitudinal or axial torque (ATA).

[0204] As discussed above, the drive shaft 11100 closure tube is movable distally to engage the end actuator 11800 burr jaw and move the 11800 burr jaw towards a 11700 staple cartridge positioned on the 11600 cartridge claw. In other words, the closing tube is configured to move the 11800 anvil from an open position (Figures 26 to 26B) to a closed position (Figures 27 to 27B) to secure the a patient against the staple cartridge 11700. In such cases, the closing tube, comprising housing 11110, connector plates 11120 and distal housing 11130 slide distally from the hinge joint 11200 during a closing stroke . When the end actuator 11500 is in an open, non-articulated configuration, now with reference to Figure 26, the connector plates 11120 extend in a direction that is slightly transverse to the central longitudinal axis LA of the drive shaft 11100. More specifically, a CA geometry axis extending between joints 11115 and 11125 is slightly transverse to the longitudinal geometry LA of drive axis 11100 when end actuator 11500 is in an open, non-articulated configuration. When the 11500 end actuator is pivoted in relation to the right (Figure 26A) or to the right (Figure 26B), the orientation of the AC axis in relation to the central longitudinal axis LA may change.

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

[0206] In addition to the above, the orientation of an AA geometry axis defined between the pivot pivot 11210 and the distal pivot 11125 of the 11120 connector plates changes as the end actuator 11500 is pivoted. Referring to Figure 26, the AA axis extends at an angle 8 with respect to the CA axis when the end actuator 11500 is in an open, non-hinged configuration. When the 11500 end actuator is pivoted in an open configuration on the right (Figure 26A), the angle B decreases. When the 11500 end actuator is hinged in an open configuration on the left (Figure 26B), the angle À increases. At no time, however, the AA axis is collinear with or parallel to the CA axis when the 11500 open end actuator is pivoted. Instead, the AA axis is transverse to the CA axis when the end actuator 11500 is pivoted in an open configuration.

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

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

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

11402. In at least one aspect, the 11400 hinge lock comprises

end a cantilever bundle where the distal end 11402 includes a fixed end and the proximal end 11404 includes a free end. The proximal end 11404 is positioned in a cavity 11184 defined in the structure of the drive shaft 11180 and is configured to move laterally in and in the opposite direction to the 11310 hinge actuator actuator, as described in more detail below.

[0210] In addition to the above, the proximal end 11404 of joint lock 11400 comprises one or more teeth 11406 defined therein that are configured to engage the joint actuator actuator 11310. As shown in Figure 40, teeth 11406 they are arranged in a longitudinal matrix; however, any suitable arrangement can be used. The actuator of the 11310 hinge actuator comprises a 11316 longitudinal tooth array defined therein that is configured to be engaged by the hinge lock 11406 teeth. Referring to Figure 41, the 11180 drive shaft structure further comprises a longitudinal tooth array 11186 defined therein that is configured to be engaged by the hinge lock 11406 teeth. When hinge lock 11400 is in a fully locked state, as described in greater detail below, the hinge lock 11406 are engaged with the teeth of the drive actuator 11316 and the teeth of the drive shaft structure 11186, so that hinge lock 11400 locks the hinge actuator actuator 11310 to the frame of the drive shaft 11180 and prevents, or at least inhibits, the relative movement between the actuator of the 11310 articulation drive and the structure of the drive shaft 11180.

[0211] In addition to the above, the articulation lock

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

[0212] As discussed further above, the drive shaft 11100 of the surgical instrument 11000 comprises a closing tube 11110 that is advanced distally during a closing stroke to close the end actuator 11500. Before the closing stroke, the lock hinge 11400 is movable between its self-locking and unlocked configurations to allow the 11500 end actuator to be pivoted by the pivot drive system

tion 11300. However, during the closing stroke, the closing tube 11110 is configured to engage the hinge lock 11400 and place or secure the hinge lock 11400 in its fully locked configuration. More specifically, the closure tube 11110 comprises a projection, or flap, 11118 configured to engage a cam surface 11408 defined on the rear side of the joint lock 11400 and prevent the teeth of the joint lock 11406 from separating from the teeth of the actuator of actuator 11316 and of the teeth of the drive shaft structure 11186. When the closing tube 11110 is retracted proximally to open the end actuator 11500, the flap 11118 disengages from the hinge lock 11400 and the hinge lock 11400 is free to move between their self-locked and unlocked positions, as discussed above, so that the 11500 end actuator can be pivoted once again.

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

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

[0215] In addition to the above, the proximal region 11150 defines a central longitudinal geometric axis. The central region 11160 extends along the longitudinal geometric axis and is centered in

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

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

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

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

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

The circumference of the proximal region 11150 and the circumference of the distal region 11170 are the same, but may be different in other modalities.

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

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

[0222] In addition to the above, the outer tube 11110 of the drive shaft 11100 includes a longitudinal portion 11160 and an enlarged distal end 11170 (Figure 80). Again with reference to Figure 40, the entire hinge lock 11400 is positioned on the longitudinal portion 11160 and not on the extended distal end.

11170. However, arrangements are made in which at least a portion of the 11400 hinge lock is positioned at the widened distal end 11170. In at least one of these Cases, the 11400 hinge lock is mounted on the drive shaft structure so that the distal end 11402 of hinge lock 11400 is at the raised distal end 11170 of outer tube 11110. In certain cases, hinge lock 11400 is again arranged so that the movable end of hinge lock 11400 is positioned at the end increased distal 11170 from outer tube 11110. In several cases, the entire hinge lock 11400 is positioned at the enlarged distal end 11170.

[0223] Now returning to Figure 46, a surgical instrument 14000 comprises a drive shaft 14100, an end actuator

11500 and, in addition, a pivot drive system including a pivot actuator 14310 configured to pivot the end actuator 11500. The drive shaft 14100 comprises a pivot lock system configured to selectively lock the actuator of the hinge actuator 14310 and end actuator 14500 in position. The hinge lock system comprises a hinge lock 14400 that includes the proximal and distal ends mounted on a frame 14180 of the drive shaft 14100. In at least one aspect, the hinge lock 14400 comprises a fixed beam and / or simply supported on both ends. The hinge lock 14400 additionally comprises an intermediate portion 14404 positioned in a cavity 14184 defined in the drive shaft structure 14180 which is configured to move laterally towards and away from a hinge actuator actuator 14310 of the system articulation actuator 14300. Similar to the above, articulation lock 14400 comprises one or more portions of spring 14403 configured to allow articulation lock 14400 to flex towards and away from articulation actuator 14310 .

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

[0225] The 14420 locking plate comprises a shoulder-shaped part 14424 that is positioned under the actuator of the 14310 pivoting actuator. The teeth of the 14426 locking plate are defined on a side edge of the 14424 shoulder-shaped part. and are substantially aligned with the teeth 14316 defined in the 14310 hinge actuator actuator. In at least one case, the teeth of the 14316 hinge actuator are aligned along a first geometric axis of the teeth and the teeth of the plate locking elements 14406 are defined along a second tooth geometric axis that is parallel, or at least substantially parallel, to the first tooth geometric axis. In several cases, the actuator teeth of the 14316 actuator are defined in a plane that is parallel to a plane including the teeth of the lock plate 14406. Such arrangements allow the hinge lock 14400 to simultaneously engage the lock plate 14420 and the actuator of the articulation actuator 14310. Although the first geometrical axis of the teeth and the second geometrical axis of the teeth are parallel to a longitudinal geometrical axis of the drive axis 14100, modalities are contemplated in which the first geometrical axis of the teeth and the second geometric axis of the teeth are

in relation to the longitudinal axis of the drive axis 14100.

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

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

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

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

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

[0229] When the hinge lock 14400 moves to its configuration completely locked by the closing tube, again with reference to Figure 46, the hinge lock 14400 pushes the lock plate 14420 against a wall on the side side 14183 of the drive shaft 14184 cavity. In fact, hinge lock 14400 engages lock plate 14420 with enough force to secure lock plate 14420 against side wall 14183, so lock plate 14420 does not it can move, or at least move substantially, longitudinally in relation to the drive shaft structure 14180. Locking plate 14420 comprises one or more projections 14422 extending therefrom that are configured to enter, crack and / or deflect the side wall 14183 from the drive shaft cavity 14184 when the lock plate 14420 is pushed against the side wall 14183 to prevent, or at least reduce the possibility of the lock plate 144 20 move longitudinally in relation to the 14180 drive shaft structure.

[0230] In addition to the above, the 14180 drive shaft structure comprises one or more cavities, or openings,

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

[0231] A 15000 surgical instrument is illustrated in Figures 47 to 49 and is similar to the 14000 surgical instrument in many respects, most of which will not be repeated here, for the sake of brevity. Among other things, the 15000 surgical instrument comprises a drive shaft, an 11500 end actuator and a hinge actuator system including a 14310 hinge actuator actuator. The 15000 surgical instrument additionally comprises a locking system. joint that includes a joint lock 15400 which is, similar to the above, movable between a self-locking position, an unlocked position and a completely locked position. The articulation lock system additionally comprises a lock plate 15420 which is similar to the lock plate

14420 in many ways. For example, lock plate 15420 is movable laterally in engagement with wall 14183. In addition, for example, lock plate 15420 is movable longitudinally to float in a suitable locked position in which a tooth array 15426 defined on the lock plate 15420 engages with the teeth 14406 of the joint lock 15400, as shown in Figure 48. Having said that, the drive shaft of the surgical instrument 15000 additionally comprises a distal spring 15429 positioned between the lock plate 15420 and a distal end wall 15427 defined in the drive shaft structure and, in addition, a proximal spring 15429 positioned between the lock plate 15420 and a proximal end wall 15427 defined in the drive shaft structure. The springs 15429 are configured to position the lock plate 15420 in a centralized or balanced position between the end walls 15427, which is illustrated in Figure 47. Such a centralized position creates a proximal gap (PG) and a distal gap (DG) between the end walls 15427 and the lock plate 15420 which are the same, or at least substantially the same, with each other. That said, the springs 15429 can experience different deflections or loads when the lock plate 15420 rests in engagement with the locking joint 15400, as shown in Figure 49, which can create the uneven spans PG and DG.

[0232] A surgical instrument 16000 is illustrated in Figures 50 to 52 and is similar to surgical instruments 14000 and 15000 in many respects, most of which will not be repeated here, for the sake of brevity. Among other things, the 16000 surgical instrument comprises a drive shaft, an 11500 end actuator and a pivot actuator system including a 16310 articulation actuator. Referring mainly to Figure 50, the 16000 surgical instrument it further comprises a hinge lock system that includes a 16400 hinge lock which is, similar to the above, configurable in a self-locking configuration, an unlocked configuration and a completely locked configuration. The hinge lock system additionally comprises a lock plate 16420 which is similar to the lock plate 14420 in many respects. For example, lock plate 16420 is movable laterally in engagement with wall 14183, as shown in Figure 51. In addition, for example, lock plate 16420 is movable longitudinally to float in a suitable locked position in which teeth 16426 lock plate 16420 are engaged with teeth 16406 of joint lock 16400, as shown in Figure 52. In addition, teeth 16406 of joint lock 16400, teeth 16426 of lock plate 16420 and lock teeth 16316 of the articulation actuators 16310 are configured and arranged to provide a plurality of positions, or permutations of positions, in which the articulation lock 16400 can lock the articulation actuator 16310 to the locking plate 16420. For example, the locking system of articulation reached a completely locked configuration in a set of positions illustrated in Figure 51 and a completely locked configuration in a different set of positions illustrated in Figure to 52.

[0233] The adaptability discussed above of the joint locking system can be achieved through tooth pitch of the joint lock teeth 16406, the joint drive teeth 16316 and the lock plate teeth 16426. For example, referring mainly to Figure 50, the articulation lock 16406 teeth are defined in a first step 16407, the articulation driver 16316 teeth are defined in a second step 16317, and the lock plate teeth 16426 are defined. defined in a third step

16427. The first step is different from the second step and the third step - the second step is different from the first step and the third step - and the third step is different from the first step and the second step, although arrangements are foreseen in which two of the first step, the second step and the third interval are the same. Again with reference to Figure 50, the third step 16427 of the teeth of the lock plate 16426 is greater than the second step 16317 of the teeth of the 16316 hinge driver, and the second step 16317 is greater than the first step 16407 of the teeth of the articulation lock 16406, although any suitable arrangement can be used.

[0234] A 17000 surgical instrument is illustrated in Figures 53 to 56 and is similar to the 11000 surgical instrument in many respects, most of which will not be repeated here, for the sake of brevity. The surgical instrument 17000 comprises a drive shaft, an end actuator 11500 pivotally connected to the drive shaft around an articulation joint 11200 and a joint actuator system configured to articulate the end actuator in around the articulation joint 11200. Similar to the above, the articulation actuation system comprises a | 17320 articulation connection pivotally mounted to the clamp 11600 around a pin 11620 and a 17310 articulation actuator mounted swiveling to the joint connection 17320 around a pin 17315. The surgical instrument 17000 additionally comprises a joint lock 17400 movably mounted to a structure of the driving shaft of the surgical instrument 17000 which is movable between an unlocked position and a locked position. The hinge lock 17400 comprises a distal end 17402 fixedly mounted to the drive shaft structure and a proximal end 17404 mounted slidably to the drive shaft structure. More specifically, the drive shaft structure comprises a pin extending into an opening defined at the distal end 17402 of the hinge lock 17400 and a guide projection 17114 extending into an elongated opening defined at the proximal end 17404. In certain cases, the drive shaft structure may comprise two or more pins that extend into the openings defined at the distal end 17402 of the hinge lock 17400 to secure the distal end 17402 to the drive shaft structure and prevent the distal end 17402 rotates with respect to the drive shaft structure. As a result of the above, at least the proximal end 17404 of the articulation lock 17400 is movable with respect to the drive shaft structure to engage the 17310 articulation actuator and lock the articulation system and end actuator 11500 in position .

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

[0236] In addition to the above, surgical instrument 17000 does not include a biasing member configured to move hinge lock 17400 towards hinge trigger 17310 other than a closing member, or tube, 17110. Closing tube 17110 it is configured to engage the 17400 hinge lock and move the 17400 hinge lock from its unlocked position (Figure 54) to its partially locked (Figure 55) and completely locked (Figure 56) positions. Similar to the above, the closing tube 17110 comprises a cam 17118 configured to engage a defined cam surface over the hinge lock 17400, although other arrangements can be used. Closing tube 17110 is configured to move hinge lock 17400 between its unlocked position and its partially locked position when closing tube 17110 is moved distally through a partial closing stroke (PCs) that at least partially closes the 11500 end actuator. In such cases, the 11500 end actuator of the 17000 surgical instrument can be used to hold a patient's tissue, for example. Closing tube 17110 is configured to move hinge lock 17400 to its fully locked position when closing tube 17110 is moved distally through a full closing stroke (FCS) that completely closes end 11500 actuator. In some cases, the end actuator 11500 of the 17000 surgical instrument can be used to hold a patient's tissue, for example.

[0237] As discussed above, the locking force applied to the 17310 hinge actuator by the 17400 hinge lock increases as the 17110 closing tube advances distally. In other words, the joint locking force is a function of the stroke of the 17110 closing tube. In addition to the above, with reference now to Figure 57, the locking force between the 17310 articulation driver and the hinge lock 17400 is represented by line 17101. As shown in Figure 57, the hinge lock teeth 17406 initially engage with the hinge trigger teeth 17316 during the partial closing stroke. In at least one case, such initial engagement of teeth 17406 and 17316 occurs after approximately 0.050 "of the closing stroke of the closing tube 17110, although any suitable distance can be used. Notably, such initial engagement of teeth 17406 and 17316 does not necessarily coincide with the end of the partial closing stroke; instead, it can occur at some point during the partial closing stroke (PCS) .This also occurs at some point during the total closing stroke (FCS) However, such an initial engagement does not comprise a coupling lock force, instead a coupling lock force between teeth 17406 and 17316 is only established at some point during the total closing stroke (FCS). minus one case, the entire closing stroke (FCS) has a length of approximately 0.260 ", for example.

[0238] An 18000 surgical instrument is illustrated in Figures 58 to 60 and is similar to surgical instruments 11000 and 17000 in many respects, most of which will not be repeated here, for the sake of brevity. The 18000 surgical instrument comprises a drive shaft, a 11500 end actuator swiveled to the drive shaft around a pivot joint and a pivot system configured to pivot the 11500 end actuator. The drive shaft it comprises a structure 18180 including the first and second longitudinal racks of teeth 18186 that are parallel, or at least substantially parallel to each other, although the racks of teeth 18186 may extend transversely with respect to each other. The surgical instrument 18000 additionally comprises a hinge lock 18400 and a closing member including a cam 18118. The hinge lock 18400 includes a first lock arm 18410 configured to engage the first longitudinal tooth rack 18186 and a second locking arm 18420 configured to engage the second longitudinal tooth rack 18186. Referring mainly to figures 59 and 60, the first locking arm 18410 comprises a first cam surface 18415 defined therein and the second locking arm 18420 comprises a second cam surface 18425 defined therein that is configured to be contacted by cam 18118 during a closing stroke of the closing member and displaced or flexed outward in a fully locked engagement with the longitudinal racks of the teeth 18186. In addition, one or both lock arms 18410 and 18420 also engage the locking air the end actuator 11500 in place when locking arms 18410 and 18420 are moved outwardly in engagement with the 18180 drive shaft structure.

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

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

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

[0242] In addition to the above, the 19180 drive shaft structure comprises a proximal guide protrusion 19182 and a distal guide protrusion 19184. The proximal guide protrusion

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

[0243] In addition to the above, the hinge lock 19400 additionally comprises a longitudinal cam slot 19408 defined therein and the closing member 19110 comprises a cam pin 19188 positioned in the cam slot 19408. When the closing member 19110 is in a non-actuated or open position (Figure 61), the cam pin 19188 is positioned in a proximal portion 19408a of the cam slot 19408. When the closing member 19110 is moved distally to an even position - partially actuated, or partially closed, as shown in Figure 62, the cam pin 19188 moves to a central portion

19408b of the cam slot 19408. In such cases, the cam pin 19188 moves the articulation lock 19400 towards the articulation actuator 19310. In such cases, however, the 19406 teeth of the articulation lock 19400 may not be engaged with the teeth 19316 of the articulation actuator 19310 and, as a result, the articulation actuator 19310 can still move to articulate the end actuator 11500 in relation to the drive shaft 19100. As a result, the actuator end 11500 can be articulated when the closing stroke of closing member 19110 has only been partially completed.

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

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

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

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

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

[0248] A 20000 surgical instrument is illustrated in Figures 66 to 68 and is similar to surgical instruments 11000, 17000, 18000 and 19000 in many respects, most of which will not be repeated here, for the sake of brevity. The surgical instrument 20000 comprises a drive shaft that includes a 20110 closing tube, an end actuator 11500 pivotally mounted to the drive shaft around a hinge joint 11200 and a hinge system configured to pivot the end actuator 11500 in relation to the drive shaft. Similar to the above, the pivot system comprises a pivot link 20320 pivotally attached to the 11500 end actuator and, in addition, a pivot actuator 20310 pivotally attached to the pivot link 20320. In use, the pivot actuator 20310 moves proximally and / or distally to activate hinge connection 20320 and hinge end actuator 11500. The surgical instrument 20000 additionally comprises a hinge lock system comprising a 20400 hinge lock gear mounted swiveling to a drive shaft structure around a fixed geometry axis. The articulation lock gear 20400 comprises an annular tooth array 20406 that is engaged in engagement with a longitudinal tooth array 20316 defined in the articulation actuator 20310. As a result, with reference generally to Figure 66, the lock gear articulation 20400 will rotate in response to the proximal and / or distal movement of the articulation actuator 20310 until the articulation lock 20400 gear is locked in position by the closing tube 20110, as shown in Figure 68.

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

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

[0251] A 21000 surgical instrument is illustrated in Figures 69 to 71 and is similar to surgical instruments 11000, 17000, 18000, 19000 and 20000 in many respects, most of which will not be repeated here,

for the sake of brevity. The surgical instrument 21000 comprises a drive shaft that includes a closing member 21110, an end actuator 11500 pivotally mounted to the drive shaft around a hinge joint 11200 and a hinge system that includes an actuator. articulation 21130 configured to articulate end actuator 11500 in relation to the drive shaft. The surgical instrument 21000 additionally comprises an articulation lock system comprising a 21400 articulation lock gear rotatably mounted to a drive shaft structure around a fixed geometry axis. The hinge lock gear 21400 comprises an annular tooth array 21406 that is engaged in engagement with a longitudinal hinge matrix 21316 defined on the hinge actuator 21310. As a result, with reference generally to Figure 69, the hinge lock gear 21400 rotates in response to the proximal and / or distal longitudinal movement of the articulation actuator 21310 until, as described in more detail below, the 21400 articulation lock gear is locked in position by the closing member 21110 (Figure 71) .

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

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

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

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

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

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

[0257] In addition to the above, the thread pitch on the 22350 threaded pivot screw can be selected to avoid recoil within the 22300 pivot drive system. Put another way, a steep pitch of the threads set on the drive screw 22350 pivot would be able to withstand a force and / or torque transmitted proximally from the end actuator

11500 via the articulation drive system 22300 and, as a result, you can prevent the 11500 end actuator from being unintentionally articulated. As such, the thread pitch can serve as an integral hinge lock with the hinge drive system 22300. In at least one case, the hinge drive screw comprises an ACME drive screw, for example.

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

23000.

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

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

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

[0262] In addition to the above, the channels 11190 and 11590 do not extend into the articulation joint 11200 and, in addition, the firing bar 12910 may not be supported within the articulation joint 11200. When the actuator of end 11500 is in a non-hinged configuration (Figure 34), the 12910 firing bar is unlikely to buckle within the 11120 pivot joint during the clamp firing stroke - however, the 12910 firing bar is likely to warp laterally during the clamp firing stroke it increases when the 11500 end actuator is in an articulated configuration (Figures 34A and 34B). To reduce the possibility of such deformation, the surgical instrument 12000 additionally comprises a firing rod support 12400 configured to support firing rod 12910. The firing rod support 12400 comprises a proximal portion 12410 connected to the structure of the firing shaft. drive 11180, a distal portion 12430 connected to the frame of the end actuator 11580 and an intermediate portion 12420 extending between the proximal portion 12410 and the distal portion 12430. Portions 12410, 12420 and 12430 of the firing bar holder 12400 are formed fully; however, other modalities are envisaged in which portions 12410, 12420 and 12430 are assembled together and / or comprise separate components.

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

[0264] In several cases, the firing rod 12910 is comprised of a plurality of parallel layers, or at least substantially parallel. The layers are affixed to a distal cutting member and can partially translate or slide longitudinally in relation to each other - especially within the 11200 hinge joint. Each of these layers is configured to transmit a load in the same direction, that is, proximally or distally, although such layers can move, or slide, relative to each other. In addition to the above, such layers can widen laterally relative to each other - especially within the articulation joint 11200 - when the end actuator 11500 has been articulated. The intermediate portion 12420 of the firing bar holder 12400 comprises a plurality of connected control elements which can at least reduce, if not prevent, the relative lateral widening of the firing bar layers. Alternatively, as mentioned above, one or more of the control elements can be disconnected from each other.

[0265] In addition to or instead of the 12400 firing bar holder, the surgical instrument 12000 comprises one or more dividers that separate and control the firing bar 12910 layers. Referring to Figures 34 to 34B, the drive 11110 comprises a divider 12920 positioned within the firing bar layers

12910. Two layers of the 12910 firing bar are positioned on one side of the 12920 divider, while two layers are positioned on the other side of the 12920 divider, although any suitable arrangement can be used. The divider 12920 prevents half the layers of the firing bar 12910 from extending outward when the end actuator 11500 is pivoted. In other words, the divider 12920 prevents the two rightmost layers of the firing bar from expanding to the left when the end actuator 11500 is turned to the right (Figure 34A) and, similarly, the divider 12920 prevents the two leftmost layers of the firing bar from widening to the right when the end actuator 11500 is left-wired (Figure 34B). The divider 12920 extends through the hinge joint 11200 and the firing bar support 12400 and into the end actuator 11500, and can flex when the end actuator 11500 is pivoted. Consequently, in such cases, divisor 12920 is flexible. The divider 12920 is mounted on the 11180 frame of the drive shaft 11110 and does not move in relation to the 11180 frame; however, modalities are foreseen in which the divider 12920 is not mounted to the 11180 structure and can float within the firing bar layers.

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

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

[0268] In addition to the above, the first side plate 13410 comprises a distal portion 13416 which is fixedly mounted to the end actuator support 13580 and does not move, or at least move substantially, in relation to the actuator structure. end pain 13580. Similarly, the second side plate 13420 comprises a distal portion 13426 which is fixedly mounted to the structure of the end actuator 13580 and does not move, or at least move substantially, with respect to the structure of the end actuator 13580. The first side plate 13410 comprises a proximal portion 13412 that is slidably mounted on the structure of the drive shaft 13180, so that the first side plate 13410 can translate in relation to the structure of the drive shaft 13180 when the 13500 end actuator is pivoted. The proximal portion 13412 comprises a head that is slidable within a chamber, or cavity, 13185 defined within the structure of the drive shaft 13180 that can limit the displacement of the firing bar support 13400. Similarly, the second plate side 13420 comprises a proximal portion 13422 which is slidably mounted on the drive shaft structure 13180 so that the firing rod holder 13400 can move in relation to the drive shaft structure 13180 when the end actuator 13500 is articulated. The proximal portion 13422 comprises a head that is slidable within the chamber 13185 defined within the structure of the drive shaft 13180 which can also limit the displacement of the firing bar holder 13400.

[0269] The first side plate 13410 comprises a flexible portion 13414 positioned on the articulation joint 11200 which allows the distal portion 13416 of the first side plate 13410 to flex in relation to the proximal portion 13412 and accommodate the articulation of the end actuator 13500 The flexible portion 13414 extends laterally from the first side plate 13410 and comprises a hinge including the spans 13413 defined therein, which allow rotation within the first side plate 13410. In addition to or instead of the above, the first plate side 13410 comprises longitudinal openings 13415 defined therein that allow the first side plate 13410 to flex within the end actuator 13500 and accommodate the hinge of the end actuator 13500. The first side plate 13410 can comprise any number and configuration of openings and / or recesses defined therein in any suitable location that is configured to allow the first side plate 13410 flexes during pivoting of end actuator 13500. Similarly, second side plate 13412 comprises a flexible portion 13424 positioned on pivot joint 11200 that allows distal portion 13426 of second side plate 13420 to flex in in relation to the proximal portion 13422 and accommodates the articulation of the end actuator 13500. The flexible portion 13424 extends laterally from the first side plate 13420 and comprises a hinge including the gaps defined therein, which allow rotation within the second side plate 13420. In addition to or instead of the above, the second side plate 13420 comprises longitudinal openings defined therein that allow the second side plate 13420 to flex within the end actuator 13500 and accommodate the end actuator hinge 13500. The second side plate 13420 can comprise any number and configuration of openings and / or reenters Suitable instances defined therein in any suitable location that is configured to allow the second side plate 13420 to flex during the articulation of the end actuator 13500.

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

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

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

[0273] Referring mainly to Figure 83, each weld 24930 of firing member 24900 comprises a weld line that is configured to firmly secure firing bar 24910 to cutting member 24920 and, at the same time, provide a flexible connection between the same. Each 24930 weld comprises a joining weld 24931 that connects cutting member 24920 to the distal ends of plates 24911 and 24912 and is placed under tension and / or compression when a longitudinal firing force is transmitted through firing member 24900 The junction weld is orthogonal, or at least substantially orthogonal to a longitudinal firing (FA) geometric axis of the firing member 24900. The junction weld 24931 can comprise any suitable configuration, such as a square, square configuration closed, single chamfer, double chamfer, single J, double J, single V, double V, single U, double U, flange, swelling and / or T configuration, for example.

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

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

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

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

[0278] In an effort to shorten the overall length of the staple cartridge without sacrificing the length of the stapled tissue, the surgical staple cartridge 25200 shown in Figure 85 comprises a cartridge body 25210 including a shortened tip 25250 located at a distal end thereof, generically designated as 25202. The shortened tip 25250 has a base 25252 which is defined by a second length 25254 that extends a distance between the end of the staple line 25056 and a rounded distal tip 25242 of the cartridge clamps 25200. The second length 25254 of the shortened tip 25250 is minimized by dulling the stop area for the wedge slide 25270 (see Figure 89). While the shortened rounded tip 25250 of the staple cartridge 25200 in Figure 85 still provides a stopping area for the wedge slider, it may be necessary to make additional accommodation for storage, as will be discussed below. The rounded distal tip 25242 is formed at an angle y from the base 25252 of the staple cartridge 25200.

[0279] When comparing the staple cartridges 25200 and 25100 shown in Figures 85 and 86, respectively, the reader should recognize that the second length 25254 is shorter than the first length 25154. As a result, the length of the staple cartridge 25200 beyond the end of the 25056 staple line is minimized to allow for improved spatial access in a surgical site, among other things. The shortened tip 25250 also prevents the rounded distal tip 25242 from perforating a seal in a trocar system, as is further discussed below. In addition, a person will recognize that the angle y of the rounded distal tip 25242 of the staple cartridge 25200 with respect to the base 25252 is greater than the angle o of the sharp distal tip 25142 of the staple cartridge

25100 relative to base 25152. For example, the rounded distal tip 25242 can extend at an angle of approximately 45 to 50 degrees from the base 25252 of the staple cartridge 25200, while the sharp distal tip 25142 can extend at an angle of approximately 30 degrees to the base 25152 of the 25100 staple cartridge. The steeper angle of the rounded distal tip 25242 provides increased stability in all distal regions of the 25200 staple cartridge structure.

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

[0281] Figure 87 illustrates an embodiment of a triple clamp driver 25240 within the clamp cartridge 25200 to support and drive three clamps 25260. Clamp driver 25240 comprises a first driver portion 25342, a second driver portion 25344 and a third driver portion 25346. A central base member 25348 connects the first portion of driver 25342 and the third portion of driver 25346 to the second portion of driver 25344. The first portion of driver 25342 is positioned at least partially distal to the second driver portion 25344.

In addition, the third portion of the driver 25346 is positioned at least partially distal to the second portion of the driver 25344. Several of the first clamp drivers 25240 are mounted in a sliding manner within the corresponding clamp cavities 25220 from the three rows longitudinal slots 25221, 25222, 25223 on one side of the elongated slot 25230. In other words, each first clamp driver 25240 is configured to support three clamps 25260: a clamp 25260 stored inside a clamp cavity 25220 in the first longitudinal row 25221; a clamp 25260 stored within a clamp cavity 25220 in the second longitudinal row 25222; a clip 25260 stored inside a cavity of clips 25220 in the third longitudinal row 25223. Due to the distal position of the first portion of the driver 25342 and the third portion of the driver 25346 in relation to the second portion of the driver 25344, the clips 25260 are fired in a backward arrow configuration. As shown in Figure 89, the last clamps 25260 in the first longitudinal row 25221 and in the third longitudinal row 25223 are closer to the shortened end 25250 of the staple cartridge 25200 than the last clamp 25260 in the second longitudinal row 25222.

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

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

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

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

25220.

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

[0287] As shown in Figures 87 to 90, the elongated slot 25230 of the staple cartridge 25200 is configured to receive a portion of a trigger assembly 25280. The trigger assembly 25280 is configured to push the slider 25270 distally to eject the staples 25260 stored inside the staple wells 25220 and deform the staples 25260 against an anvil positioned opposite the staple cartridge 25200. More specifically, a coupling member 25282 pushes the wedge slide 25270 distally from the staple cartridge 25200. The slide in slot 25270 it has four rails, two inner rails 25272 and two outer rails 25274 which are connected to each other via a central member 25276. An inner rail 25272 and an outer rail 25274 are positioned on one side of the slot elongated 25230, while the other inner rail 25272 and the other outer rail 25272 are positioned on the opposite side of the elongated slot 25230. accordingly, the inner rails 25272 pass through the inner channels 25212 defined within the cartridge body 25210 and engage the rear facing edge 25349 of the drivers 25240 that support the clamps 25260 to cause the clamps to fire towards the anvil.

Likewise, the outer rails 25274 pass through the external channels 25214 defined within the cartridge body 25210 and engage the portions of the drivers 25240 that support the clamps 25260 to push the clamps towards the anvil.

The distal movement of the wedge slide 25270 causes the rails 25272, 25274 to make contact with the rear facing edges 25349 of the clamp drivers 25240, pushing the clamps 25240 upwards to eject and push the clamps 25260 from the clamp cartridge 25200 in the tissue captured between the staple cartridge 25200 and an opposite anvil.

Coupling member 25282 also comprises a cutting edge 25284 that cuts the fabric as coupling member 25282 advances distally to eject the clips 25260 from the cartridge body 25210.

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

[0289] Figure 89 represents the wedge slide 25270 of the firing set 25280 stopped at the shortened tip 25250 after the completion of the staple firing stroke. The shortened tip 25250 comprises a plurality of openings 25292, 25294 at the distal end of the shortened tip 25250 to receive the four rails 25272,

25274. The shortened tip 25250 additionally comprises an opening 25296 configured to receive the central slide member 25276 of the wedge slide 25270. In this way, the portions of the rails 25272, 25274 and the central slide member 25276 of the wedge slide 25270 are exposed at the distal end 25202 of the clamp cartridge 25200. The openings 25292, 25294 are continuations of channels 25212, 25214 within which Rails 25272, 25274 of the wedge slide 25270 slide. Two Internal openings 25292 are configured to receive the two inner rails 25272 of the wedge slide 25270, while two external openings 25294 are configured to receive the two outer rails 25274 of the wedge slide 25270. One central opening 25296 in the center of the distal portion 25202 of the shortened tip 25250 is configured to receive the central member 25276 of the wedge slider

25270. The openings 25292, 25294, 25296 at the distal end 25202 of the shortened tip 25250 allow the staple firing stroke to be completed and the wedge slide 25270 to stop at a shortened distal end.

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

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

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

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

25203. The first surgical instrument 25201 additionally comprises a first drive shaft 25206 which is pivotally connected to the first end actuator 25202. The first end actuator 25202 is articulated around a joint 25208 positioned between the first end actuator 25202? and the first drive shaft 25206. The first end actuator 25202 is capable of being articulated at an angle a with respect to

the first drive shaft 25206. Similarly, the elongated clamp cartridge 25100 is part of a second end actuator 25102 in a second surgical instrument 25101 which also includes an anvil 25103. Also, the second surgical instrument 25101 additionally comprises a second drive shaft 25106 which is pivotally connected to the second end actuator 25102. The second end actuator 25102 is articulable around a hinge joint 25108 positioned between the second end actuator 25102 and the second drive shaft 25106. The second end actuator 25102 is capable of being articulated at an angle B in relation to the second drive shaft

25106.

[0293] In addition to the above, in use, the physician inserts the 25202 end actuator through a cannula, or trocar, and into a patient when the 25202 end actuator is in its non-articulated condition. Once through the trocar, end actuator 25202 can be articulated as shown in Figure 91. At such a point, drive shaft 25206 can be moved to position end actuator 25202 in the pelvic cavity. Similar steps would be used to position the end actuator 25102.

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

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

[0296] An extreme difference between the distal end of a staple cartridge and the distal end of an anvil can damage a trocar when the end actuator is inserted through it. Referring to Figure 92, an end actuator 25810 comprises a distal end 25802, an anvil 25820 and a staple cartridge 25830. Staple cartridge 25830 has a shortened and rounded nose 25840 similar to the shortened nose 25250 over the shortened cartridge clamps 25200 in Figure 85. As can be seen in Figures 92 and 93, anvil 25820 has a protective tip

25822 on it. Protective tip 25822 is dimensioned and positioned over anvil 25820 in a way that makes anvil 25820 shorter in length than the staple cartridge 25830. Thus, the shortened tip 25840 of the staple cartridge 25830 extends distally from anvil 25820. Protective tip 25822 can be integrally formed (molded, machined, etc.) over the distal end 25802 of anvil 25820 or can comprise a separate part configured to receive a complementary portion of the anvil. A more detailed discussion of the protective tips can be found in the publication of patent application US 2008/0169328, entitled IMPROVED BUTTRESS MATERIAL FOR USE WITH A SURGICAL STAPLER, whose full disclosure is hereby incorporated by reference in its entirety for reference. nity.

[0297] As can be seen in Figures 92 and 93, the protective tip 25822 of the anvil 25820 has a first curved or angled outer surface 25824, and a second curved or angled outer surface 25826 configured to form a stubby distal end over anvil 25820. The first angled outer surface 25824 extends downwardly from a top surface 25828 of the anvil 25820 at a first angle q. The second angled outer surface 25826 extends downwardly from the first angled outer surface 25824 towards the staple cartridge 25830 at a second angle 8. The second angle 8 is greater than the first angle q. Several modalities are predictions in which the angle 8 measures, for example, approximately 90 degrees. Other embodiments of the protective tip 25822 are provided for having only one of a first inclined outer surface 25824 or a second inclined outer surface 25826. The first inclined outer surface 25824 is used to deflect a centering ring from a tro-carte seal assembly during insertion of the 25810 end actuator through the trocar. When the second angle 8 is 90 degrees apart, and / or when the first and second curved external surfaces 25824, 25826 are not continuous, the anvil 25820 can pierce through a trocar seal or it can displace the centering ring from one trocar sealing system, as will be discussed in more detail below.

[0298] A protective tip can be attached to an anvil in any suitable way. Figures 94 to 99 illustrate exemplary modalities of protective tips formed separately 25922, 26022, and various methods for attaching them to an anvil. As shown in Figures 94 to 96, a distal portion of an anvil 25920 comprises a clamping feature that includes clamping members 25927, 25929 that are configured to fit in a retentive manner with complementary retaining channels 25926, 25928 formed on the protective tip 25922. More specifically, a central retention channel 25928 is formed within the protective tip 25922 to receive a central fixing member 25929 of the anvil 25920. A pair of lateral retention channels 25296 is formed within the protective tip 25922 to receive a pair of side fixing members 25927 corresponding to anvil 25920. Figure 96 is a cross-sectional view of anvil 25920 of Figure 94 taken along line 96- 96 in Figure 95 in a disassembled configuration showing the alignment of the retention channels 25926, 25928 with their respective fixing members 25927, 25929. An elongated slot 25994 extends longitudinally from the end proximal ade 25904 of the anvil 25920 towards the distal end 25902 of the anvil 25920. The elongated slot 25994 is configured to receive a portion of the firing set discussed here.

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

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

25922. A through hole 25925 also extends through the central fixing member 25929 of the anvil 25920 so that when the protective tip 25922 is attached to the anvil 25920, the through holes 25925 align to facilitate the insertion of a rivet 25924 therein. Figure 95 is a cross-sectional view of anvil 25920 represented in Figure 94 taken along line 95-95 in Figure 94 in a disassembled configuration that illustrates a rivet assembly for removably securing protective tip 25922 to the anvil 25920. In addition, or alternatively to the above, the protective tip 25922 can be fixed to the anvil 25920 by means of adhesives such as, for example, cyanoacrylates, light-curable acrylics, polyurethanes, silicones, epoxies and / or adhesives curable by ultraviolet, such as HENKEL LOCTITEO. In any case, a combination of fixing members and retaining channels can be provided on the anvil 25920 and the protective tip 25922. Still other forms of fixations and fixing arrangements can be used to fix the protective tip 25922 to the anvil.

25920.

[0300] Figures 97 to 99 illustrate another modality of a tip fixation arrangement. A distal portion of an anvil 26020 comprises fixing members 26027 which are configured to fit retentively with the complementary retention channels 26026 defined in the protective tip 26022. In addition, a central retention channel 26028 defined within the protective tip 26022? is configured to receive a central fixing member 26029 of anvil 26020. Figure 98 is a cross-sectional view of anvil 26020 of Figure 97 taken along line 98-98 in Figure

97 in a disassembled configuration showing the alignment of the retaining channels 26026, 26028 with their respective fixing members 26027, 26029. Figure 99 is a cross-sectional view of the anvil 26020 of Figure 97, taken along the line 99-99 in Figure 97 in a mounted configuration. Protective tip 26022 is attached to the 26020 anvil using a compression fitting. The central fixing member 26029 is snapped into the central retaining channel 26028, remaining in place due to the geometry of the central retaining channel 26028. The central fixing member 26029 of the anvil 26020 in Figure 98 has a trapezoidal shape. which is imitated by the central retaining channel 26028. An elongated slot 26094 extends longitudinally from a proximal end 26004 of the anvil 26020 towards the distal end 26002 of the anvil 26020. The elongated slot 26094 is configured to receive a portion of the firing set discussed here.

[0301] In addition, or alternatively to the above, the protective tip 26022 can be fixed to the anvil 26020 by means of adhesives such as, for example, cyanoacrylates, light-curable acrylics, polyurethanes, silicones, epoxies and / or curable adhesives by ultraviolet, for example, HENKEL LOCTITEO. In various embodiments, a combination of fixing members and retaining channels can be provided on the 26020 anvil and the 26022 protective tip. Still other forms of fixations and fixing arrangements can be used to fix the 26022 protective tip to the 26020 anvil. Figures 97 to 99 further illustrate means to assist a user in attaching the protective tip 26022 to the anvil 26020. Figure 97 illustrates the protective tip 26022 positioned removably within a temporary support

26030. In order to release the protective tip 26022 releasably to the bib 26020, the user presses the temporary support 26030 and the bib 26020 together. The temporary support 26030 can provide an additional sterilization barrier to the protective tip 26022 while the protective tip 26022 is attached to the anvil 26020. In addition, the temporary support 26030 provides the user with an object that is more substantial to hold when fixing the protective tip 26022 to anvil 26020, since the protective tip 26022 may be small in size. It is envisaged that the temporary support 26030 can be used in various types of protective tips, including the other modalities presented in the present invention.

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

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

[0304] Figure 100 shows an example end actuator 27000 comprising an anvil 27010 and a staple cartridge 27020. The staple cartridge 27020 comprises a shortened and rounded nose 27022 similar to the shortened nose 25250 shown on the cartridge staples 25200 in Figure 85. The distal end 27202 of anvil 27010 is pointed and does not have a protective tip, like the one shown in Figure 92. As can be seen in Figure 100, the anvil 27010 has a shorter length than the clamps 27020. In other words, the shortened tip 27022 of the clamp cartridge 27020 extends longitudinally beyond the distal end 27002 of the anvil 27010. Before insertion of the end actuator 27000 through the trocar seal system 27040, the first port sealing 27052 and the second sealing port 27054 extend inward to prevent gas from escaping the surgical site. Figure 101 represents the end actuator 27000 of Figure 100 partially inserted in the trocar seal system

27040. The shortened tip 27022 of the staple cartridge 27020 is the first component of the end actuator 27000 to contact the first and second sealing ports 27052, 27054 of the trocar seal system 27040, tilting the set of floating seal 27050 to one side. Due to its rounded shape, the shortened tip 27022 does not damage the second seal port 27054 despite exerting a force on it.

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

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

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

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

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

[0309] In addition to the above, the end actuator comprises a movable anvil claw relative to the cartridge claw between an open, or not clamped, position and a closed, or clamped position. In alternative embodiments, the jaw of the cartridge is mobile in relation to the jaw of the anvil. In any case, the anvil claw comprises a distal anvil end that is supported by the first staple cartridge and the second staple cartridge, depending on which staple cartridge is positioned in the cartridge claw. . The distal anvil end is supported at a first location on the first cartridge jaw and at a second location on the second cartridge jaw. In many cases, the first location and the second location may not be at the same distance from the detail of the given proximal cartridge grip. In some cases, however, they may be at the same distance from the detail of the given proximal cartridge jaw. In addition, in

In many cases, the first location is located at a first distance from the distal end of the first staple cartridge while the second location is located at a second, or different, distance from the distal end of the second staple cartridge. In use, a patient's tissue will be positioned between the anvil clamp and the cartridge claw, but, however, the staple cartridge support locations will still support the anvil claw, or the applied clamping load by the anvil claw.

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

[0311] In addition to the above, the anvil claw will

flex when it moves to its closed position.

Due to the different cartridge lengths of the staple cartridges, the deflection of the anvil claw can be different depending on which staple cartridge is positioned in the cartridge claw.

As a result, the staple gap between the anvil clamp and the staple drivers of the first cartridge claw may differ from the staple gap between the anvil clamp and the staple drivers of the second cartridge claw. .

In some cases, the gap in the staple formation gap is negligible, and the staples ejected from the first staple cartridge and the second staple cartridge will be formed at the same height, or at least at the lowest suitable and sufficient heights for staple the fabric caught between the anvil claw and the cartridge claw.

In such cases, the unformed height of the clamps on the first clamp cartridge can be equal to the unformed height of the clamps on the second clamp cartridge.

In other cases, the unformed height of the clamps on the first clamp cartridge is different from the unformed height of the clamps on the second clamp cartridge.

In such cases, the higher staples can be used on the first staple cartridge and the shorter staples can be used on the second staple cartridge, for example, depending on the deflection and / or anticipated orientation of the anvil claw when closed against the first and the second staple cartridges.

In at least one of these cases, each of the staples in the first staple cartridge has an unformed height in a first unformed height range and each of the staples in the second staple cartridge has an unformed height in a second stripe of unformed height.

In some cases, the first unformed height band is completely different from the second unformed height band while in other cases, the first unformed height band partially overlaps the second unformed height band.

[0312] As discussed above, the first staple cartridge and the second staple cartridge are selectively positioned on the end actuator's cartridge jaw and, in addition to the above, the cartridge jaw additionally comprises a support or bottom surface configured for support the staple cartridges when they are seated on the cartridge gripper. Such support can comprise a vertical detail. In several cases, the first support location on the first staple cartridge and the second support location on the second staple cartridge, discussed above, have the same vertical distance from the vertical detail of the cartridge grip. The vertical distance is measured orthogonally from the vertical reference, but can be measured in any suitable way. In other cases, the first support location on the first staple cartridge has a different vertical height from the second support location on the second staple cartridge. In such cases, the orientation and / or deflection of the anvil claw when the anvil claw is in its secured position may be different as a result of the first local support site and the second support site having different vertical heights. . Such different vertical heights can occur when the distal end, or tip, of the first staple cartridge, is different from the distal end of the second staple cartridge, among other reasons.

[0313] 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 Application Publication No. 2012/0298719, for example, reveals several examples of a robotic surgical instrument system with more Details.

[0314] The surgical instrument systems described here have been described in connection with the implantation and deformation of the clamps; however, the embodiments described in the present invention are not | 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

[0315] Example 1 - A surgical instrument comprising an end actuator. The end actuator comprises a cartridge jaw and an anvil jaw, one of which between the cartridge jaw and the anvil jaw is rotatable with respect to the other around a geometric axis of the cover. The surgical instrument additionally comprises a drive shaft that comprises a structure that defines a longitudinal drive shaft geometric axis and a closing actuator, the closing actuator being translatable in relation to the structure. The closing actuator

it comprises a proximal portion, a distal portion and a connection. The connection is pivotally connected to the proximal portion around a geometric axis of the proximal connection and to the distal portion around a geometric axis of the distal connection. The geometric axis of the proximal connection and the geometric axis of the distal connection define a geometric axis of the longitudinal connection between them. The surgical instrument additionally comprises a hinge joint, the end actuator being swiveled to the drive shaft around a hinge axis defined by the hinge joint.
