[0052] Many specific details are listed herein to provide a thorough understanding of the overall structure, function, manufacture, and use of the embodiments described in the specification and shown in the drawings. Well-known operations, parts, and elements are not described in detail to avoid obscuring the embodiments described in the specification. The reader will understand that the embodiments described and shown herein are non-limiting examples, so that it can be recognized that the specific structural and functional details disclosed herein can be representative and illustrative. These embodiments can be modified and changed without departing from the scope of the claims.

[0053] The terms "proximal" and "distal" are used herein relative to a clinician manipulating the handle portion of a surgical instrument. The term "proximal" refers to the portion closest to the clinician, and the term "distal" refers to the portion positioned away from the clinician. It should also be understood that for brevity and clarity, spatial terms such as "vertical," "horizontal," "upper," and "lower" may be used herein in conjunction with the accompanying drawings. However, surgical instruments are used in many orientations and positions, and these terms are not intended to be limiting and / or absolute.

[0054] Various exemplary devices and methods are provided for performing laparoscopic and minimally invasive surgical procedures. However, the reader will readily appreciate that the various methods and devices disclosed herein can be used in a variety of surgical procedures and applications, including, for example, in conjunction with open surgical procedures. Continuing to refer to this detailed description, the reader will further appreciate that the various instruments disclosed herein can be inserted into the body in any manner, such as through a natural cavity, through an incision or puncture formed in tissue, etc. The working portion or end effector portion of the instrument can be inserted directly into the patient's body or can be inserted through an access device having a working frame, through which the end effector and elongated shaft of the surgical instrument can be advanced.

[0055] See now Figures 1 to 5 , a surgical stapling system 110000 is shown, which includes a shaft 110002 and an end effector 110004 extending from the shaft 110002. The end effector 110004 includes a first jaw 110006 and a second jaw 110008. The first jaw 110006 includes an elongated channel 110007 and a staple cartridge 110010. The staple cartridge 110010 can be inserted into the elongated channel 110007 and can be removed from the elongated channel. Specifically, the staple cartridge 110010 includes a tab 110011 located on each lateral side thereof, which is snapped into a corresponding recess 110009 defined in the elongated channel 110007. Alternatively, the staple cartridge 110010 may not be removable from the first jaw 110006 or at least not easily replaceable from the first jaw.

[0056] The second jaw 110008 includes an anvil configured to deform the nail ejected from the nail magazine 110010. The second jaw 110008 is capable of being moved in an open position ( Figure 5 ) and closed position ( Figure 4 ) between the end effector 110004 and the end effector 110006; however, the first jaw 110006 may be capable of pivoting relative to the second jaw 110008. The surgical stapling system 110000 also includes an articulation joint 110013 that is configured to allow the end effector 110004 to rotate or articulate relative to the axis 110002. Alternatively, the surgical stapling system 11000 may not include an articulation joint.

[0057] The staple cartridge 110010 includes a cartridge body 110012. The cartridge body 110012 includes: a proximal end 110014; a distal end 110016; and a platform 110018 extending between the proximal end 110014 and the distal end 110016. In use, the staple cartridge 110010 is positioned on a first side of the tissue to be stapled and the anvil 110008 is positioned on a second side of the tissue. The anvil 110008 moves toward the staple cartridge 110010 (see Figure 4 and Figure 5 ) to compress and clamp the tissue against the platform 110018. Then, the nails 110021 removably stored in the magazine body 110012 can be deployed into the tissue. The magazine body 110012 includes nail cavities 110020 defined therein, wherein the nails are removably stored in the nail cavities 110020. The nail cavities 110020 are arranged in six longitudinal rows. Three rows of nail cavities are positioned on the first side of the longitudinal slot 110022, and three rows of nail cavities are positioned on the second side of the longitudinal slot 110022. Other arrangements of nail cavities and nails are also possible.

[0058] The nails are supported in the cartridge body 110012 by the nail drivers. The nails supported on the nail drivers can be seen in U.S. Patent Application Publication No. 2021 / 0059672, entitled "SURGICAL INSTRUMENT WITH WIRELESS COMMUNICATION BETWEEN ACONTROL UNIT OF A ROBOTIC SYSTEM AND REMOTE SENSOR" filed on September 14, 2020, the entire contents of which are incorporated herein by reference. The driver is movable between a first unfired position and a second fired position to eject the nails from the nail cartridge 110020. The driver is retained in the cartridge body 110012 by a retainer 110024, which extends around the bottom of the cartridge body 110012 and includes a resilient member configured to grip the cartridge body 110012 and retain the retainer 110024 to the cartridge body 110012. The driver can be moved between its unfired position and its fired position by a slide 110026. The slide 110026 is movable between a proximal position adjacent to the proximal end 110014 and a distal position adjacent to the distal end 110016. The slide 110026 includes a plurality of ramp surfaces configured to slide under the driver and lift the driver toward the anvil 110008, and the nail is supported thereon. Alternatively, the nail may not be supported by the nail driver, but the nail may include an integral driving surface that is directly engaged by the slide 110026 to lift the nail, examples of which are described in U.S. Patent Application Publication No. 2015 / 0173756, entitled "SURGICAL CUTTING AND STAPLING METHODS," filed on December 23, 2013, which is hereby incorporated by reference in its entirety.

[0059] In addition to the above, the slide 110026 is moved distally by a firing member or firing actuator, as seen and described elsewhere herein. The firing actuator is configured to contact the slide 110026 and push the slide 110026 toward the distal end 110016. The longitudinal slot 110022 defined in the cartridge body 110012 is configured to receive the firing actuator. The anvil 110008 also includes a slot defined therein for receiving the firing actuator. The firing actuator also includes a first cam engaging the first jaw 110006 and a second cam engaging the second jaw 110008 in the slot of the anvil. As the firing actuator is advanced distally, the first cam and the second cam can control the distance or tissue gap between the platform 110018 and the anvil 110008 of the nail magazine 110010. The firing actuator also includes a knife configured to cut into tissue captured between the nail magazine 110010 and the anvil 110008. It is desirable that the knife is positioned at least partially close to the ramp surface so that the nail is ejected before the knife.

[0060] According to the present invention, anvil 110008 can be moved from an open position to a closed position using a closing actuator that is controlled separately from the firing actuator. Therefore, the firing actuator can be considered as a part of a firing system that is separate from the closing actuator and can be operated significantly. Anvil 110008 may include a ramp on its proximal end, and the closing actuator includes a closing tube that can move distally to engage the ramp and cam anvil 110008 to a closed position. In the closed position, the first cam and the second cam of the firing actuator translate distally and hold anvil 110008 in the closed position. In such an arrangement, in order to convert anvil 110008 to an open position, the closing tube is retracted toward the proximal side, and a spring positioned in end effector 110004 biases anvil 110008 to an open position. The anvil 110008 may include a tab, and the closure tube defines a hole that engages the tab when the closure tube moves proximally, thereby actively transforming the anvil 110008 to the open position. Exemplary closure actuators and closure tubes are described in U.S. Patent Application Publication No. 2021 / 0059672, filed on September 14, 2020, entitled "SURGICALINSTRUMENT WITH WIRELESS COMMUNICATION BETWEEN A CONTROL UNIT OF A ROBOTICSYSTEM AND REMOTE SENSOR," the entire contents of which are incorporated herein by reference. Various other closure actuators are contemplated by the present disclosure and discussed elsewhere herein.

[0061] The anvil 110008 can be moved from an open position to a closed position using a firing actuator. Thus, the anvil 110008 may include a ramp extending proximally from a wall defining a slot, and during a first portion of a stroke of the firing actuator, when the firing actuator moves from a first proximal position to a second intermediate position to move the anvil 110008 to a closed position, the ramp is engaged by the firing actuator. The first portion of the stroke of the firing actuator may be approximately 0.110"-0.250" of the firing actuator stroke. At the end of the first portion of the stroke, during the second portion of the stroke, the firing actuator may continue to advance from the second intermediate position to the third distal side to deploy the nails from the nail magazine 110010 and cut into the tissue captured by the end effector, as described above. An exemplary firing actuator for closing the anvil and firing the nail is described in U.S. Patent No. 11,160,551, entitled "ARTICULATABLE SURGICAL STAPLING INSTRUMENTS", filed on December 21, 2016, which is hereby incorporated by reference in its entirety. When the firing actuator is used to move the anvil 110008 toward the closed position and deploy the nail from the nail magazine 110010, the firing actuator can be considered as both a closing actuator and / or a firing actuator.

[0062] After the nail magazine 110010 has been fired or at least partially fired, if necessary, the nail magazine is removed from the elongated channel 110007 and then replaced with another replaceable nail magazine. At this point, the surgical suturing system 110000 can be reused to continue suturing and cutting into patient tissue. However, the previously fired nail magazine may be accidentally loaded into the elongated channel 110007. If the firing actuator advances distally in such previously fired nail magazine, the surgical suturing system 110000 can cut patient tissue without suturing patient tissue. If the firing actuator advances distally to complete the nail firing stroke without the nail magazine being positioned in the elongated channel 110007 at all, the surgical suturing system 110000 can similarly cut patient tissue without suturing patient tissue. In addition, various surgical nail magazines may have different arrays and / or orientations of nails / fasteners therein. Depending on the specific surgical operation or application, the size of the nails or fasteners and the number of fasteners may vary depending on the type of magazine. In order to ensure that the nails are correctly crimped or formed, the surgical nail magazine must be used in conjunction with a corresponding compatible anvil having an appropriate array of nail forming recesses therein and appropriate cutting and firing components. If an "incompatible" magazine is loaded into a surgical stapling device having an anvil that does not match the nail magazine, the nails may not be correctly formed during the firing process, which may lead to catastrophic results.

[0063] Reference now Figures 6 to 8According to the present disclosure, a surgical stapling system 110100 is provided. The surgical stapling system 110100 includes a shaft 110102, an end effector 110104, a firing actuator 110106, and a lockout 110108. The shaft 110102 can be similar to the shaft 110002. The end effector 110104 can be similar to the end effector 110004.

[0064] The end actuator 110104 includes an elongated channel 110109, an anvil (not shown, but similar to anvil 110008), and an anvil pivotally coupled to the elongated channel 110109 such that the anvil can be moved in an open position (similar to the anvil 110008) relative to the elongated channel 110109. Figure 5 ) and the closed position (similar to Figure 4 ) between the pivots 110112. Figure 7 and Figure 8 As can be seen in FIG. 1 , pivot 110112 includes a defined closed axis (similar to Figure 1 Rod 110113 of the closed axis CA) shown in .

[0065] The firing actuator 110106 includes a firing drive 110114, a first push rod 110116 attached to the upper end of the firing drive 110114, and a second push rod 110118 attached to the lower end of the firing drive 110114. The first push rod 110116 and the second push rod 110118 can be driven using any suitable drive system (such as a motor drive system) to move the firing drive 110114 from a proximal position (such as Figure 7 and 8 The trigger actuator is driven to a distal position (as shown). An exemplary motor drive system is described in U.S. Patent Application Publication No. 2015 / 0173756, entitled "SURGICAL CUTTING AND STAPLING METHODS," filed on December 23, 2013, the entire contents of which are incorporated herein by reference. The firing actuator includes a body 110120, a first cam 110122, a second cam 110124, a knife 110125, and a hook 110126, which will be described in more detail below.

[0066] In operation, the firing driver 110114 can move through a stroke including a closing stroke portion and a firing stroke portion distal to and after the closing stroke portion. During the closing stroke portion, the first cam 110122 of the firing driver 110114 engages the inclined surface on the anvil to cam the anvil from the open position toward the closed position. During the firing stroke portion after the closing stroke portion and distally, the body 110120 of the firing driver 110114 engages and drives a slide (similar to the slide 110026) through the staple cartridge to deploy staples from the staple cartridge, while the knife 110125 cuts the sutured tissue. In addition, when the firing driver 110114 is advanced distally through the firing stroke portion, the second cam 110124 engages the elongated channel 110109 and the first cam 110122 engages the anvil to control the distance or tissue gap therebetween. Since the firing actuator 110106 is used to move the anvil toward the closed position prior to deploying the nails from the nail magazine, the firing actuator can also be considered a closing actuator.

[0067] The surgical stapling system 110100 also includes a flange 110151 that defines a first channel 110153 that receives and guides the first push rod 110116 and a second channel 110155 that receives and guides the second push rod 110118 during a stroke of the firing actuator.

[0068] The lockout member 110108 includes a lockout rod 110128 and a spring 110130 coupled to the lockout rod 110128. The lockout rod 110128 includes a pin 110132, a body 110134 defining a cam surface 110135 on a distal end thereof, and a tab 110136. The shaft 110102 defines a hole 110138 that receives the pin 110132 of the lockout rod 110128. See Figure 8 According to the present disclosure, the elongated channel 110109 can define a hole 110138 that receives the pin 110132 of the locking lever 110128. The locking lever 110128 can be pivoted between a locked state and an unlocked state, in which the tab 110136 is received within the hook 110126 ( Figure 6 and Figure 7 ), in the unlocked state, the tab 110136 is rotated out or displaced from the hook 110126 ( Figure 8 ). Spring 110130 is mounted to shaft 110102 and biases locking rod 110128 toward the locked state. Spring 110130 can also be mounted to the base of elongated channel 110109. Spring 110130 can include a leaf spring. The spring can include a torsion spring.

[0069] In the locked state, the tab 110136 and the hook 110126 are longitudinally aligned so that if the user attempts to drive the firing drive 110114 through its stroke portion, the tab 110136 will engage the hook 110126, thereby preventing the firing drive 110114 from moving distally. In other words, in the locked state, the lockout 110108 prevents the firing drive 110114 from moving through the closing stroke portion and the firing stroke portion of its stroke. Notably, the tab 110136 engages the hook 110126 at a location proximate to the pivot 110112, as will be explained in more detail below.

[0070] In the unlocked state, the tab 110136 is rotated out or displaced from the hook 110126 so that the tab 110136 and the hook 110126 are not longitudinally aligned. In other words, in the unlocked state, the lockout 110108 allows the firing driver 110114 to move through the closing stroke portion and the firing stroke portion of its stroke. In one aspect, since the lockout 110108 prevents the firing driver 110114 from moving through the closing stroke portion and the firing stroke portion when it is in the locked state, the lockout 110108 can be considered a closing lockout and / or a firing lockout.

[0071] Most, if not all, of the lockout member 110108 is positioned proximal to the pivot 110112. In the illustrated arrangement, most of the lockout rod 110128 is located proximal to the pivot 110112. For example, the cam surface 110135 on the distal end of the lockout rod 110128 may not be proximal to the pivot 110112, however, the contact point between the firing actuator 110106 (hook 110126) and the lockout member 110108 (tab 110136) is proximal relative to the pivot 110112, as described above. By moving the lockout member 110108 proximal to the pivot 110112, space within the end effector 110104 is freed and the lockout member 110108 moves away from the clamping point between the elongated channel 110109 and the anvil. In various embodiments, the entirety of the lockout 110108 (eg, the cam surface 110135 ) can be positioned proximal to the pivot 110112 , thereby freeing up additional space within the end effector 110104 .

[0072] In order to transition the lockout 110108 from the locked state to the unlocked state, a compatible staple cartridge is positioned within the elongated channel 110109. Figure 6 and Figure 7, the incompatible nail magazine 110140 has been removably positioned in the elongated channel 110109. Therefore, the lockout 110108 remains in the locked state, thereby preventing the firing drive 110114 from moving through the closing stroke portion and the firing stroke portion of its stroke. It is worth noting that the incompatible nail magazine 110140 does not include a key to transform the lockout 110108 to the unlocked state, as described in more detail below. Therefore, if the user attempts to drive the firing actuator 110106 through its stroke, the tab 110136 will engage the hook 110126 on the proximal side of the pivot 110112, thereby preventing the firing actuator 110106 from moving distally.

[0073] See now Figure 8 , a compatible staple cartridge 110150 has been removably positioned in the elongated channel 110109. The compatible staple cartridge 110150 includes a key 110152 extending proximally therefrom. When the staple cartridge 110150 is removably positioned in the elongated channel 110109, the key 110152 engages the cam surface 110135 of the lockout bar 110128. When the staple cartridge 110150 is moved proximally to seat the staple cartridge 110150 in the elongated channel 110109, the key 110152 engages the cam surface 110135 and rotates the tab 110136 out of longitudinal alignment with the hook 110126 of the firing drive 110114, thereby "releasing" the lockout 110108 and placing the lockout bar 110128 in an unlocked state. Notably, key 110152 comprises a length that allows key 110152 to extend proximally from staple cartridge 110150 to engage cam surface 110135. Figure 8 As shown, the point of contact between key 110152 and cam surface 110135 is located at or adjacent to pivot 110112. If lockout 110108 is positioned entirely proximal to the pivot, as described above, key 110152 includes a length that allows key 110152 to extend proximally from staple cartridge 110150 past pivot 110112 to engage cam surface 110135 at a location proximal to pivot 110112.

[0074] The staple cartridge 110150 may include a cartridge body including a key 110152. The staple cartridge 110150 may include a retainer including a key 110152. The staple cartridge 110150 may include a slider including a key 110152. If the slider includes a key, when the lockout bar 110128 is transformed to the unlocked state, the firing drive 110114 is permitted to be advanced distally through the closing stroke portion and the firing stroke portion. As the firing drive 110114 is advanced distally, the slider is also advanced distally by the firing drive 110114, thereby causing the key 110152 to gradually disengage from the cam surface 110135 of the lockout bar 110128. As the key 110152 progressively disengages from the cam surface 110135, the spring 110130 progressively biases the lockout bar 110128 toward the locked state. It is noteworthy that the hook 110126 of the firing drive 110114 extends proximally from the body 110120 to a certain length that allows the firing drive 110114 to move distally away from the tab 110136 before the spring 110130 repositions the locking rod 110128 to the locked state.

[0075] Upon completion of the firing stroke, the firing drive 110114 is retracted toward its proximal position. As the firing drive 110114 is retracted, the proximal end of the hook 110126 engages the distal end of the tab 110136, which causes the lockout bar 110128 to cam upward toward the unlocked state, thereby allowing the hook 110126 to slide under the tab 110136. Once the hook 110126 passes the tab 110136 proximally, the spring 110130 biases the lockout bar 110128 back to its locked state, thereby preventing the firing drive 110114 from advancing through another closing stroke and firing stroke until another compatible staple cartridge is positioned in the end effector 110104.

[0076] See now Figures 9 to 11 According to at least one aspect of the present disclosure, a surgical stapling system 110200 is provided. The surgical stapling system 110200 includes a shaft 110202, an end effector 110204, an articulation joint 110205, a firing actuator 110206, a closing actuator 110207, and a lockout 110208. The shaft 110202 may be similar to the shaft 110002. The end effector 110204 may be similar to the end effector 110004.

[0077] The end effector 110204 includes an elongated channel 110209, an anvil 110210, and a pivot 110212 that pivotally couples the anvil 110210 to the elongated channel 110209, such that the anvil 110210 can be in an open position (similar to Figure 5 ) and closed position (similar to Figure 4 ) are rotated between. According to the present disclosure, the pivot 110212 may include a pin. The end effector 110204 is capable of pivoting about the articulation joint 110205 relative to the shaft 110202. The anvil 110210 includes a tab 110215 extending from its proximal end, as will be discussed in more detail below.

[0078] The closure actuator 110207 includes a closure tube 110211, which can be driven using any suitable drive system (e.g., a motor drive system or a manual drive system) to move the closure tube 110211 from Fig.11 The anvil 110210 is driven to the distal position from the proximal position shown. The anvil 110210 includes a cam surface or ramp 110213 defined on the proximal end thereof. When the closure tube 110211 moves distally, the closure tube 110211 contacts the cam surface 110213 to cam or rotate the anvil 110210 from the open position toward the closed position. In order to transform the anvil 110210 to the open position, the closure tube 110211 can be retracted proximally, and the spring positioned in the end effector 110204 biases the anvil 110210 to the open position. The anvil 110210 may include a tab, and the closure tube 110211 may define a hole that engages with the tab when the closure tube 110211 moves proximally, thereby actively transforming the anvil 110210 to the open position. Exemplary closure actuators and closure tubes are described in U.S. Patent Application Publication No. 2021 / 0059672, filed on September 14, 2020, entitled "SURGICAL INSTRUMENT WITH WIRELESS COMMUNICATION BETWEEN A CONTROL UNITOF A ROBOTIC SYSTEM AND REMOTE SENSOR," which is incorporated herein by reference in its entirety. Various other closure actuators are contemplated by the present disclosure and are discussed elsewhere herein.

[0079] The firing actuator 110206 includes a firing member or firing drive 110214 and a firing rod 110216 extending proximally from the firing drive 110214. The firing rod 110216 may include a plurality of laminated strips 110217. The firing rod 110216 may be driven using any suitable drive system (such as a motor drive system) to move the firing drive 110214 from a proximal position (such as a proximal position) to a position adjacent to the firing drive 110214. Fig. 9 and 10The triggering drive 110214 includes a triggering actuator body 110220 defining a hole 110221, a first cam 110222, a second cam (not shown, but similar to the second cam 110124), a knife (not shown, but similar to the knife 110125), and a locking body 110224 pivotably connected to the triggering actuator body 110220. The locking body 110224 includes a pin 110225 extending laterally from each side thereof.

[0080] In operation, the closure tube 110211 moves through the closing stroke to convert the anvil 110210 from the open position to the closed position. Once the anvil 110210 has been placed in the closed position, the firing driver 110214 moves through the firing stroke. During the firing stroke, the body 110220 of the firing driver 110114 engages and drives the slide through the staple cartridge to deploy the staples from the staple cartridge, while the knife cuts the sutured tissue. In addition, when the firing driver 110214 is advanced distally through the firing stroke, the second cam engages the elongated channel 110209, and the first cam 110222 crosses the slot 110226 defined in the anvil 110210 and engages the lower surface 110227 of the slot 110226 to control the distance or tissue gap between the elongated channel 110209 and the anvil 110210. The surgical stapling system 110200 may not include the closing actuator 110207. Therefore, the firing actuator 110206 can be configured to be able to advance through the closing stroke portion and the firing stroke portion distal to and after the closing stroke portion. During the closing stroke portion, the firing driver 110214 engages the inclined surface on the proximal end of the anvil 110210 to move the anvil from the open position toward the closed position. During the firing stroke portion, similar to the above, the firing driver 110114 engages and drives the slide through the nail magazine to deploy nails from the nail magazine, while also controlling the distance or tissue gap between the elongated channel 110209 and the anvil 110210.

[0081] The lockout member 110208 includes a lockout rod 110228 including a body 110234 defining a cam surface 110235 on a distal end thereof and a tab 110236. The lockout rod 110228 is pivotable between a locked state and an unlocked state, in which the tab 110236 is received within the aperture 110221 of the firing drive 110214 ( Fig.10), in the unlocked state, the tab 110236 is rotated or displaced laterally from the hole 110221 of the firing drive 110214 ( Fig. 9 ). The proximal end 110237 of the body 110234 can be pivotally coupled to the shaft 110202. The proximal end 110237 of the body 110234 can be pivotally coupled to the elongated channel 110209. The lockout member 110208 can also include a spring, such as a torsion spring, which biases the lockout rod 110228 toward the locked state.

[0082] In the locked state, as described above, the tab 110236 is received within the aperture 110221 of the firing drive 110214 such that if the user attempts to drive the firing drive 110214 through its firing stroke, the tab 110236 will engage the proximal wall defined by the aperture 110221 and prevent the firing drive 110214 from moving distally. In other words, in the locked state, the lockout 110208 prevents the firing drive 110214 from moving through the firing stroke. Notably, the tab 110236 engages the proximal wall defined by the aperture 110221 at a position laterally proximal to the pivot 110212, as will be explained in more detail below.

[0083] In addition, in the locked state, the body 110234 of the lockout bar 110228 is vertically aligned with the tab 110215 defined on the proximal end of the anvil 110210, so that if the user attempts to rotate the anvil 110210 toward the closed position, the tab 110215 will engage the body 110234 of the lockout bar 110228 and prevent its rotational movement. In other words, in the locked state, the lockout bar 110228 prevents the anvil 110210 from moving to the closed position. Therefore, in the locked state, the lockout 110208 acts to prevent the anvil 110210 from closing and the firing drive 110214 from firing. Therefore, in one aspect, the lockout 110208 can be considered a closed lockout and / or a firing lockout.

[0084] In the unlocked state, as described above, the tab 110236 is laterally rotated out or displaced from the aperture 110221 of the firing drive 110214. In the unlocked state, the body 110234 of the lockout bar 110228 is also laterally displaced so that it is no longer vertically aligned with the tab 110215 defined on the anvil 110210, and therefore, if the user attempts to rotate the anvil 110210 toward the closed position, the tab 110215 will bypass the body 110234 of the lockout bar 110210 during rotation of the anvil 110228. In other words, in the unlocked state, the lockout bar 110228 allows the anvil 110210 to move to the closed position. In addition, in the unlocked state, if the user attempts to drive the firing drive 110214 through the firing stroke, the tab 110236 will not engage the proximal wall defined by the hole 110221 and prevent the firing drive 110214 from moving distally. That is, in the unlocked state, the lockout 110208 allows the firing drive 110214 to move through the firing stroke.

[0085] Most, if not all, of the lockout 110208 is located proximal to the pivot 110212. Specifically, the point of contact between the lockout 110208 (tab 110236) and the firing drive 110214 (hole 110221) is proximal relative to the pivot 110212. By moving the lockout 110208 proximal to the pivot 110212, space within the end effector 110204 is freed and the lockout 110208 moves away from the clamping point between the elongated channel 110209 and the anvil 110210. The entirety of the lockout 110108 can be positioned proximal to the pivot 110212, thereby freeing up additional space within the end effector 110204.

[0086] In order to transition the lockout 110208 from the locked state to the unlocked state, a compatible staple cartridge is positioned within the elongated channel 110209. Fig.10 , no nail magazine is removably positioned in the elongated channel 110209. Therefore, the lockout 110208 remains in the locked state, thereby preventing the anvil 110210 from rotating to the closed position and preventing the firing drive 110214 from moving through the firing stroke. Therefore, if the user attempts to drive the firing drive 110214 through the firing stroke, the tab 110236 will engage the proximal wall defined by the hole 110221 at a position proximal to the pivot 110212, thereby preventing the firing drive 110214 from moving distally. It should be understood that if an incompatible nail magazine (discussed in more detail below) that does not include a key is removably positioned in the elongated channel 110209, the lockout 110208 will also remain in the unlocked state.

[0087] See now Fig. 9, a compatible staple cartridge 110250 is removably positioned in the elongated channel 110209. The compatible staple cartridge 110250 includes a first key 110252 extending proximally therefrom. When the staple cartridge 110250 is removably positioned in the elongated channel 110209, the first key 110252 engages the cam surface 110235 of the locking rod 110228. When the staple cartridge 110250 is moved proximally to seat the staple cartridge 110250 in the elongated channel 110209, the first key 110252 engages the cam surface 110235 and rotates the tab 110236 laterally out of the aperture 110221 and the body 110234 out of vertical alignment with the tab 110215, thereby "releasing" the lockout 110208 and placing the locking rod 110228 in an unlocked state. Fig.10 As shown, the point of contact between key 110252 and cam surface 110235 is located at a position distal to pivot 110212. With lockout 110208 positioned proximally of pivot 110212 as a whole, key 110252 includes a length that allows key 110252 to extend proximally from staple cartridge 110250 past pivot 110212 to engage cam surface 110235 at a position proximal to pivot 110212.

[0088] The staple cartridge 110250 can include a cartridge body including a first key 110252. The staple cartridge 110250 can include a retainer including a first key 110252. The staple cartridge 110250 can include a slider including a first key 110252. The lockout 110208 can be considered a compatible staple cartridge lockout because a compatible staple cartridge (i.e., a staple cartridge including the first key 110252) is required in order to transition the lockout bar 110228 to an unlocked state. The absence of the first key 110252 in the staple cartridge can indicate that the staple cartridge is an incompatible staple cartridge.

[0089] As described above, the firing drive 110214 includes a firing actuator body 110220 and a locking body 110224 pivotably coupled to the firing actuator body 110220. The locking body 110224 is pivotable relative to the firing actuator body 110220 between an upward unlocked position and a downward locked position. The firing drive 110214 may further include a spring biasing the locking body 110224 toward the locked position. The end effector 110204 also includes a spring 110240 including a body 110242 and a pair of hooks 110244 extending distally from the body 110242. The proximal end of the body 110242 may be mounted to the shaft 110202. The proximal end of the body 110242 may be mounted to the elongated channel 110209.

[0090] In the locked position of the lockout body 110224, the hook 110244 of the spring 110240 "grabs" the pin 110225 to prevent the firing drive 110214 from moving distally. In other words, in the locked position of the lockout body 110224, the spring 110240 prevents the firing drive 110214 from moving through its firing stroke. In the unlocked position of the lockout body 110224, the pin 110225 rotates upward and away from the hook 110244, so that the lockout body 110224 and the firing drive 110214 can pass through the hook 110244 without being "grabbed". In other words, in the unlocked position, the spring 110240 allows the firing drive 110214 to move through its firing stroke. Therefore, the spring 110240 and the lockout body 110224 can be considered as a second lockout member, collectively referred to as a lockout member 110260. The lockout 110260 can be considered a fired lockout. The lockout 110260 can be considered a ready-to-fire lockout, as will be discussed in greater detail below.

[0091] In order to transition the lockout body 110224 from the locked position to the unlocked position, the "ready to fire" staple cartridge is positioned in the elongated channel 110209. Fig. 9 , a compatible and ready-to-fire staple cartridge 110250 is removably positioned in the elongated channel 110209. As described above, the compatible staple cartridge 110250 includes a first key 110252 that "releases" the first lockout 110208 to allow the anvil 110210 to move from the open position toward the closed position. Similarly, releasing the first lockout 110208 rotates the tab 110236 out of the hole 110221 so that the firing drive 110214 is not blocked from moving through the firing stroke via the first lockout 110208.

[0092] The compatible and ready-to-fire staple cartridge 110250 also includes a second key (not shown, but similar to other keys shown and described elsewhere herein) extending proximally therefrom. When the staple cartridge 110250 is removably positioned in the elongated channel 110209, the second key slides under the lockout body 110224 to hold the lockout body 110224 in the upward unlocked position. With the lockout body 110224 in the upward unlocked position, as described above, the lockout body 110224 is rotated upward and away from the hook 110244, so that the lockout body 110224 and the firing drive 110214 can pass through the hook 110244 without being "caught". The staple cartridge 110250 may include a sliding member that includes a second key. The spring 110240 and the lockout body 110224 can be considered a lockout that is ready to fire because a slider having a second key positioned proximally unfired thereof is required to prevent the pin 110225 on the lockout body 110224 from falling and being "caught" by the spring 110240. The absence of a second key in a staple cartridge can indicate, for example, a staple cartridge that does not have a compatible slider (a slider in a proximal position, but does not include a second key) or a slider having a second key that is not in an unfired position (a slider in a partially exhausted or exhausted position).

[0093] It should be understood that, in the case where a nail magazine including the first key 110252 but not the second key is removably positioned in the elongated channel 110209, the first lockout 110208 will be unlocked to allow the anvil 110210 to move to the closed position. However, although the tab 110236 is rotated out of the hole 110221, if the user attempts to drive the firing driver 110214 through the firing stroke, the lockout body 110224 will not have the second key to keep it in the upward unlocked position. Therefore, the lockout body 110224 will fall to the downward locked position, and the pin 110225 will be "caught" by the hook 110244 of the spring 110240, thereby preventing the firing driver 110214 from moving distally. Therefore, the surgical stapling system 110200 may include two locking members: a first locking member (compatible nail magazine locking member 110208) used as a closing and firing locking member and a second locking member (a nail magazine locking member ready to fire composed of a locking body 110224 and a spring 110240) used as a secondary firing locking member.

[0094] Reference now Fig.12 According to the present disclosure, a surgical stapling system 110300 is provided. The surgical stapling system 110300 includes a shaft 110302, an end effector 110304 extending from the shaft 110302, and a closing actuator 110306 extending through the shaft 110302. The shaft 110302 may be similar to the shaft 110002. The end effector 110304 may be similar to the end effector 110004.

[0095] The end effector 110304 includes an elongated channel 110310, an anvil 110312, and a pivot 110314 that pivotally couples the anvil 110312 to the elongated channel 110310. The pivot 110314 may include a pin. The anvil 110312 is capable of being in an open and locked position, an open and unlocked position (similar to the elongated channel 110310), and a pivot 110314 that pivotally couples the anvil 110312 to the elongated channel 110310. Figure 5 ) and closed position (similar to Figure 4 ), in the open and locked position, the distal end 110316 of the anvil 110312 rotates a first distance away from the distal end 110318 of the elongated channel 110310, in the open and unlocked position, the distal end 110316 of the anvil 110312 rotates a second distance less than the first distance away from the distal end 110318 of the elongated channel 110310, and in the closed position, the distal end 110316 of the anvil 110312 rotates a third distance less than the second distance away from the distal end 110318 of the elongated channel 110310. The anvil 110312 also includes a pin 110320 extending from its proximal end.

[0096] The closing actuator 110306 includes an elongated rod 110322 extending along a first axis and a flange 110324 extending distally from the elongated rod. The flange 110324 defines a slot 110326 that receives the pin 110320 and extends along a second axis that is transverse to the first axis of the elongated rod 110322. The slot 110326 includes a first distal end 110328 and a second proximal end 110330 that is opposite to the first distal end 110328. The pin 110320 can move along the slot 110326 between a first position corresponding to an open and locked position of the anvil 110312, a second position corresponding to an open and unlocked position of the anvil 110312, and a third position corresponding to a closed position of the anvil 110312. The second position of the pin 110320 is closer to the first end 110328 of the slot 110326 than the first position of the pin 110320. The third position of the pin 110320 is closer to the first end 110328 of the slot 110326 than the second position of the pin 110320. The first position of the pin 110320 may be a position where the pin 110320 engages the second end 110330 of the slot 110326. The third position of the pin 110320 may be a position where the pin 110320 engages the first end 110328 of the slot 110326. The first position and the second position of the pin 110320 may be positions between the first end 110328 of the slot 110326 and the second end 110330 of the slot 110326.

[0097] During the closing stroke, the closing actuator 110306 can be moved by the drive system from the first distal position toward the second proximal position to move the pin 110320 along the slot 110326, and thus the anvil 110312 is rotated from the open and unlocked position toward the closed position. However, it is worth noting that in the open and locked position of the anvil 110312, the closing actuator 110306 cannot rotate the anvil 110312 toward the closed position, as explained in more detail below. The drive system that drives the closing actuator 110306 may include a motor drive system. The drive system that drives the closing actuator 110306 may include a closing trigger, and the closing actuator 110306 can be manually moved according to the movement provided to the closing trigger by the user.

[0098] In the open and locked position of the anvil 110312, the pin 110320 is in a first position within the slot 110326. In the first position, the flange 110324 cannot apply enough torque to the pin 110320 to move the pin 110320 along the slot 110326 toward its first end 110328, and thus rotate the anvil 110312 away from the open and locked position. In other words, when the pin 110320 is in the first position, the closing actuator 110306 is prevented from moving toward the proximal side through its closing stroke. Therefore, the slot 110326 of the flange 110324 and the pin 110320 together define the closed latch 110350.

[0099] like Fig.12 As shown, the lockout 110350 can be positioned proximal to the pivot 110314. By moving the lockout 110350 closer to the pivot 110314, the space within the end effector 110304 is released and the lockout 110350 moves away from the clamping point between the elongated channel 110310 and the anvil 110312.

[0100] The closure latch 110350 can be configured in a locked state and an unlocked state. The locked state can correspond to an open and locked position of the anvil 110312 as described above, wherein the pin 110320 is positioned in the slot 110326 so that the closure actuator 110306 is prevented from moving the anvil 110312 toward the closed position. The unlocked state can correspond to an open and unlocked position of the anvil 110312 as described above, wherein the pin is positioned in the slot 110326 so that the closure actuator 110306 is permitted to move the anvil 110312 toward the closed position.

[0101] In order to transform the anvil 110312 from the open and locked position (the first position of the pin 110320) to the open and unlocked position (the second position of the pin 110320), the unlocking lever 110308 is used. The unlocking lever 110308 includes a body 110332 pivotally connected to the elongated channel 110310 using a pin 110331, a cam surface 110334 extending distally from the body 110332, and an arm 110336 extending proximally from the body 110332. The arm 110336 extends a length from the body 110332 so that when the unlocking lever 110308 is rotated (such as Fig.12 32 (counterclockwise as shown in the figure), the arm 110336 engages the proximal end of the anvil 110312 to drive or "kick" the pin 110320 from its first position to its second position, thereby transitioning the anvil 110312 from an open and locked position to an open and unlocked position, and transitioning the closed latch 100350 from a locked state to an unlocked state.

[0102] To rotate the unlocking lever 110308, as described above, a compatible staple cartridge 110340 is positioned within the elongated channel 110310. The compatible staple cartridge 110340 includes a key 110342 that engages a cam surface 110334 of the unlocking lever 110308 at a position away from the pivot 110314 when the compatible staple cartridge 110340 is positioned in the elongated channel 110310. The staple cartridge 110340 may include a cartridge body including the key 110342. The staple cartridge 110340 may include a retainer including the key 110342. The staple cartridge 110340 may include a slide including the key 110342.

[0103] The point of contact between the key 110342 and the cam surface 110334 is distal to the pivot 110314. Similar to the closed latch 100350, the unlocking lever 110308 may also be positioned proximal to the pivot 110314, thereby freeing up additional space within the end effector. If the unlocking lever 110308 is also positioned proximal to the pivot 110314, the key 110342 includes a length extending proximally from the staple cartridge 110340 through the pivot 110314 to engage the cam surface 110334 at a position proximal to the pivot 110314.

[0104] When the staple cartridge 110340 is moved proximally to seat the staple cartridge 110340 in the elongated channel 110310, the key 110342 slides along the cam surface 110334, thereby rotating the unlocking lever 110308. When the unlocking lever 110308 is rotated, the arm 110336 of the unlocking lever 110308 engages the proximal end of the anvil 110312 to move the pin 110320 toward the second position within the slot 110326, thereby transforming the anvil 110312 to the open and unlocked position and transforming the closed latch 110350 to the unlocked state. The unlocking lever 110308 also includes a tip 110338 that engages the base of the elongated channel 110310 to prevent the key 110342 of the staple cartridge 110340 from over-rotating the unlocking lever 110308 and moving the pin 110320 beyond its second position. In various embodiments, the surgical stapling system 110300 can further comprise a spring which biases the end 110338 away from the base of the elongated channel 110310 and the arm 110336 away from the pin 110320 .

[0105] With the pin 110320 in the second position within the slot 110326, the closing actuator 110306 is able to apply sufficient torque to the pin 110320 to move the pin 110320 within the slot 110326 toward its first end 110328 and thereby rotate the anvil 110312 from the open and unlocked position toward the closed position. Thus, in the unlocked state of the closure latch 110350, the closing actuator 110306 is permitted to move proximally through its closing stroke to place the anvil 110312 in the closed position. Once the anvil 110312 is in the closed position, the clinician is able to perform a nail firing function to deploy nails from the nail magazine, as described elsewhere herein.

[0106] The surgical stapling system 110300 may further include a firing actuator, such as firing actuator 110106 (described above) or firing actuator 110206 (described above), which can be moved through a firing stroke to deploy staples from the staple cartridge 110340 after the closing actuator 110306 has placed the anvil 110312 in the closed position. The surgical stapling system 110300 may further include a firing lockout, such as lockout 110108 or lockout 110260, which prevents the firing driver of the firing actuator from being advanced through the staple cartridge 110340 unless the staple cartridge 110340 is a compatible and / or ready-to-fire staple cartridge. Thus, in this way, the surgical stapling system 110300 may include two lockouts: one that prevents the anvil 110312 from rotating toward the closed position (the closed lockout 110350), and the other that prevents the firing actuator from advancing through its firing stroke unless a compatible and / or ready-to-fire staple cartridge is positioned within the end effector (such as the lockout 110108 or the lockout 110260). The staple cartridge 110340 may include two keys that independently transform each lockout-the closed lockout 110350 and the firing lockout to their respective unlocked states. The key 110342 may transform the closed lockout 110350 and the firing lockout to their respective unlocked states.

[0107] Reference now Figures 13 to 15 According to the present disclosure, a surgical stapling system 110400 is provided. The surgical stapling system 110400 includes a firing actuator 110402 and a locking member 110404.

[0108] The firing actuator 110402 includes a firing drive 110406, a first push rod 110408 attached to the upper end of the firing drive 110406, and a second push rod 110410 attached to the lower end of the firing drive 110406. The first push rod 110408 and the second push rod 110410 can be driven using any suitable drive system, such as a motor drive system, to drive the firing drive 110406 ​​from a proximal position toward a distal position. An exemplary motor drive system is described in U.S. Patent Application Publication No. 2015 / 0173756, entitled “SURGICAL CUTTING AND STAPLING METHODS,” filed on December 23, 2013, the entire contents of which are incorporated herein by reference. The firing drive 110406 ​​includes a body 110412, a first cam 110414, a second cam 110416, a knife 110418 and a hook 110420, as will be described in more detail below.

[0109] In one aspect, the surgical stapling system 110400 further comprises an end effector (similar to end effector 110004) comprising an elongated channel (similar to elongated channel 110007), an anvil (similar to anvil 110008), and a pivot that pivotally couples the anvil to the elongated channel about a closing axis (similar to closing axis CA). In one aspect, the pivot comprises a pin. The anvil is capable of pivoting relative to the elongated channel about the closing axis in an open position (similar to closing axis CA). Figure 5 ) and closed position (similar to Figure 4 ) between. It should be noted that the end effector of the surgical stapling system 110400 is pivoted between Figure 13-15 404 are hidden in order to help properly illustrate the firing actuator 100402 and the locking member 110404, which will be described in more detail below.

[0110] In operation, the firing drive 110406 ​​is capable of moving through a stroke including a closing stroke portion and a firing stroke portion distal to the closing stroke portion. During the closing stroke portion, the first cam 110414 of the firing drive 110406 ​​engages a ramp on the anvil to cam the anvil from the open position toward the closed position. During the firing stroke portion after the closing stroke portion and distally, the body 110412 of the firing drive 110406 ​​engages and drives a sled similar to the sled 110026 through a staple cartridge (such as staple cartridge 110010) to deploy staples therefrom while the knife 110418 cuts the stapled tissue. In addition, when the firing drive 110406 ​​is advanced distally through the firing stroke portion, the second cam 110416 engages the elongated channel and the first cam 110414 engages the anvil to control the distance or tissue gap therebetween. In one aspect, the firing actuator 110402 can also be considered a closing actuator because the firing actuator 110402 is used to move the anvil toward the closed position prior to deploying the staples from the staple cartridge.

[0111] The lockout 110404 includes a flange 110430, a first lockout 110440 pivotally coupled to a first lateral side of the flange 110430, and a second lockout 110450 pivotally coupled to a second lateral side of the flange 110430. The flange 110430 defines a first recess 110432 that receives the first push rod 110408 and guides the first push rod 110408 during the closing stroke portion and the firing stroke portion. The flange 110430 also defines a second recess 110434 that receives the second push rod 110410 and guides the second push rod 110410 during the closing stroke portion and the firing stroke portion. The surgical stapling system 110400 may also include a shaft similar to the shaft 110002, and the flange 110430 is mounted to the shaft.

[0112] The first locking member 110440 includes a first locking arm 110442 pivotally coupled to the flange 110430 and a first tab 110444 extending laterally from the first locking arm 110442. The first locking arm 110442 is pivotable relative to the flange 110430 between a first locked state and a first unlocked state, in which the first tab 110444 is received within the hook 110420 ( Fig.15 ), in the first unlocked state, the first tab 110444 is rotated out of the hook 110420 ( Fig.13 and 14 ). The spring can bias the first lockout 110440 toward the first locked state. In the first locked state, the first tab 110444 and the hook 110420 are longitudinally aligned so that if a user attempts to drive the firing drive 110406 ​​through the closing stroke portion and the firing stroke portion, the first tab 110444 will engage the hook 110420 at a position proximal to the closing axis defined by the pivot, thereby preventing the firing drive 110406 ​​from moving distally. When a compatible staple cartridge (i.e., a staple cartridge including a first authentication key) is required in order to transition the first lockout 110440 to the first unlocked position, the first lockout 110440 can be considered a compatible staple cartridge lockout, as will be explained in more detail below.

[0113] Similarly, the second latching member 110450 includes a second latching arm 110452 pivotally coupled to the flange 110430 and a second tab 110454 extending laterally from the second latching arm 110452 toward the first latching arm 110442. The second latching member 110450 is pivotable relative to the flange 110430 between a second locked state and a second unlocked state, in which the second tab 110454 is received within the hook 110420 ( Fig.14 and Fig.15 ), in the second unlocked state, the second tab 110454 is rotated out of the hook 110420 ( Fig.13 ). The spring can bias the second lockout 110450 toward the second locked state. The same spring that biases the first lockout 110440 toward the first locked state can also bias the second lockout 110450 toward the second locked state. In the second locked state, the second tab 110454 and the hook 110420 are longitudinally aligned so that if a user attempts to drive the firing drive 110406 ​​through the closing stroke portion and the firing stroke portion, the second tab 110454 will engage the hook 110420 at a position proximal to the closing axis defined by the pivot, thereby preventing the firing drive 110406 ​​from moving distally. The second lockout 110450 can be considered a read firing cartridge lockout because an unspent cartridge requires the second lockout to be transitioned to the second unlocked position, as will be explained in more detail below.

[0114] Most, if not all, of the lockout 110404 is positioned proximally relative to the pivot between the anvil and the elongated channel. In particular, as described above, the contact point between the firing actuator 110402 (hook 110420) and the lockout 110404 (first tab 110444 and / or second tab 110454) is proximally relative to the pivot. By moving the lockout 110404 proximally of the pivot, space within the end effector is freed and the lockout 110404 moves away from the clamping point between the elongated channel and the anvil. The entire lockout 110404 can be positioned proximally of the pivot, thereby freeing up additional space within the end effector.

[0115] In use, the lockout 110404 blocks the advancement of the firing drive 110406 ​​unless a compatible and ready-to-fire staple cartridge is positioned in the elongated channel (such as the elongated channel 110007) of the surgical stapling system 110400. The staple cartridge may include two discrete authentication keys, wherein the first authentication key is configured to enable the first lockout 110440 to transition from a first locked state to a first unlocked state, and the second authentication key is configured to enable the second lockout 110450 to transition from a second locked state to a second unlocked state. With the first lockout 110440 and the second lockout 110450 in their respective unlocked positions, the firing drive 110406 ​​is permitted to advance through the closing stroke and the firing stroke. However, if one or both of the first lockout 110440 and the second lockout 110450 are in their respective locked positions, the firing drive 110406 ​​is blocked from advancing through the closing stroke portion and the firing stroke portion. Because the lockout 110404 prevents the firing drive 110406 ​​from moving through the closing stroke portion and the firing stroke portion when one or both of the first lockout 110404 and the second lockout 110450 are in their respective locked positions, the lockout 110440 can be considered a closing lockout and / or a firing lockout.

[0116] See now Fig.13, a staple cartridge 110500 is provided, which includes a cartridge body 110502 and a slider (not shown, but similar to the slider 110026). The cartridge body 110502 includes a first key 110503, and the slider includes a second key 110505. When the staple cartridge 110500 is positioned in the elongated channel, the first key 110503 engages a cam surface 110446 on the first latch arm 110442 to rotate the first latch arm 110440 from a first locked state toward a first unlocked state. When the staple cartridge 110500 is moved proximally to place the staple cartridge 110500 in the elongated channel, the first key 110503 leaves the cam surface 110446 and then engages the first latch arm 110442 to continue to cam the first latch 110440 toward the first unlocked state, and thus moves the first tab 110444 out of the hook 110420. The contact point between the first key 110503 and the cam surface 110446 can be located distally relative to the pivot between the anvil and the elongated channel of the end effector. The contact point between the first key 110503 and the cam surface 110446 can be located proximally relative to the pivot between the anvil and the elongated channel of the end effector. Thus, the first key 110503 can include a length that allows the key 110503 to extend proximally from the staple cartridge 110500 past the pivot to engage the cam surface 110446 at a position proximal to the pivot.

[0117] Similarly, when the staple cartridge 110500 is positioned in the elongated channel, the second key 110505 engages the cam surface 110456 on the second latch arm 110452 to rotate the second latch arm 110450 from the second locked state toward the second unlocked state. When the staple cartridge 110500 is moved proximally to seat the staple cartridge 110500 in the elongated channel, the second key 110505 disengages the cam surface 110456 and then engages the second latch arm 110452 to continue camming the second latch 110450 toward the second unlocked state and thereby moving the second tab 110454 out of the hook 110420. With both latches 110440, 110450 rotated to their respective unlocked positions, the firing drive 110406 ​​is permitted to move through the closing stroke portion and the firing stroke portion. The contact point between the second key 110505 and the cam surface 110456 can be located distally relative to the pivot between the anvil and the elongated channel of the end effector. The contact point between the second key 110505 and the cam surface 110456 can be located proximally relative to the pivot between the anvil and the elongated channel of the end effector. Thus, the second key 110505 can include a length that allows the key 110505 to extend proximally from the staple cartridge 110500 past the pivot to engage the cam surface 110456 at a position proximal to the pivot.

[0118] Now refer to Fig.14, the staple cartridge 110500 has been replaced by a first replacement staple cartridge 110510, the first replacement staple cartridge comprising a cartridge body 110512, the cartridge body comprising a first key 100513 and a slider (not shown, but similar to the slider 110026), the slider particularly not including a second key. The absence of the second key of the first replacement staple cartridge 110510 may indicate, for example, a staple cartridge without a compatible slider (a slider in a proximal position, but not including a second key) or a slider with a second key that is not in an unfired position (a slider in a partially exhausted or exhausted position). Thus, when the first replacement staple cartridge 110510 is removably positioned in the elongated channel, the first lockout 110440 transitions to a first unlocked state (via the first key 110513, as described above), but the second lockout 110550 remains in a locked state. In this state, the lockout 110404 blocks the firing drive 110406 ​​from moving distally. As described above, only one of the lockout members 110440, 110450 need be in its respective locked state to prevent the firing drive 110406 ​​from moving through the closing stroke portion and the firing stroke portion.

[0119] See now Fig.15 , the first replacement staple cartridge 110510 has been replaced by a second replacement staple cartridge 110520, the second replacement staple cartridge comprising a cartridge body 110522 and a slide (not shown, but similar to slide 110026), the cartridge body in particular not including a first key, and the slide in particular not including a second key. As described above, the absence of a second key from the second replacement staple cartridge 110520 may indicate, for example, a staple cartridge that does not have a compatible slide (a slide in a proximal position, but does not include a second key) or a slide with a second key that is not in an unfired position (a slide in a partially depleted or depleted position). In addition, the absence of a first key in the second replacement staple cartridge 110520 may indicate that the second replacement staple cartridge 110520 is an incompatible staple cartridge. Thus, when the second replacement nail magazine 110520 is removably positioned in the slender channel, the first lockout member 110440 and the second lockout member 110450 remain in their respective locked states, thereby preventing the firing drive 110406 ​​from moving distally through the closing stroke portion and the firing stroke portion.

[0120] When a key is formed or otherwise provided on a slider of an otherwise compatible cartridge, one of ordinary skill in the art will appreciate that the slider must be in the unfired, proximal-most position in the cartridge in order for the key to unlockably interact with the latch of the surgical instrument. For example, if a slider that originally included an appropriate unlocking key has been moved distally away from the unfired, proximal-most position, indicating that at least some of the staples have been fired and are missing (by distal advancement of the slider), the slider will move out of position to unlockably engage the corresponding latch. Such a system will thereby prevent the use of a previously fired or partially fired staple cartridge.

[0121] Many of the surgical instrument systems described herein are actuated by electric motors; however, the surgical instrument systems described herein may be actuated in any suitable manner. For example, the surgical instrument systems described herein may be actuated by a manually operated trigger. The motors disclosed herein may include a portion or portions of a robotic control system.

The above-described specific embodiments and the following claims are intended to cover all such modifications and variations.

[0123] Various aspects of the subject matter described herein are set forth in the following numbered examples:

[0124] Embodiment - A surgical stapling system (110000, 110100, 110200, 110300, 110400) includes an end actuator (110004, 110104, 110204, 110304), a closing actuator (110106, 110207, 110306, 110402) capable of moving from a first position toward a second position during a closing stroke, and a closing latch (110108, 110208, 110308, 110404). The end actuator includes an elongated channel (110007, 110109, 110209, 110310), an anvil (110110, 110210, 110312), and a pivot (110112, 110212, 110314) that pivotally connects the anvil to the elongated channel. The anvil can pivot between an open position and a closed position relative to the elongated channel. The closing actuator is configured to enable the anvil to move toward the closed position. The closing latch can be configured in a locked state and an unlocked state, in which the closing latch engages the closing actuator at a position relative to the proximal side of the pivot to prevent the closing actuator from moving the anvil toward the closed position, and in the unlocked state, the closing actuator is allowed to move the anvil toward the closed position.
