It will be further understood that it can be inserted into the body in any way, such as through a hole. The working or end effector portions of these instruments can be inserted directly into the patient's body or through an access device having a working channel through which the end effector and elongated shaft of the surgical instrument can be advanced. You can also.

  The surgical stapling system can include a shaft and an end effector extending from the shaft. The end effector includes a first jaw and a second jaw. The first jaw includes a staple cartridge. The staple cartridge is insertable into the first jaw and removable from the first jaw, but the staple cartridge is not removable from the first jaw or at least not easily replaceable. Other embodiments are also contemplated. The second jaw includes an anvil configured to deform the staples ejected from the staple cartridge. The second jaw is pivotable relative to the first jaw about the closure axis, but the first jaw is pivotable relative to the second jaw, Embodiments are also contemplated. The surgical stapling system further comprises an articulation joint configured to allow the end effector to rotate or articulate relative to the shaft. The end effector is rotatable about an articulation axis extending through the articulation joint. Other embodiments that do not include a joint joint are also contemplated.

  The staple cartridge includes a cartridge body. The cartridge body includes a proximal end, a distal end, and a deck extending between the proximal and distal ends. In use, the staple cartridge is positioned on the first side of the tissue to be stapled and the anvil is positioned on the second side of the tissue. The anvil is moved toward the staple cartridge to compress and clamp the tissue against the deck. Subsequently, staples removably stored in the cartridge body can be deployed in the tissue. The cartridge body includes a staple cavity defined therein, and the staple is removably stored within the staple cavity. The staple cavities are arranged in six longitudinal rows. Three rows of staple cavities are positioned on the first side of the longitudinal slot, and three rows of staple cavities are positioned on the second side of the longitudinal slot. Other arrangements of staple cavities and staples may be possible.

  Staples are supported by a staple driver in the cartridge body. The driver is movable between a first or unfired position and a second or fired position that ejects staples from the staple cavity. The driver includes an elastic member that is held within the cartridge body by a holder that extends around the bottom of the cartridge body and that is configured to grip the cartridge body and hold the holder against the cartridge body. . Drivers can be moved between their unfired positions and their fired positions by a sled. The sled is movable between a proximal position adjacent to the proximal end and a distal position adjacent to the distal end. The sled includes a plurality of inclined surfaces configured to slide under the driver and lift the driver, with the staples supported thereon and toward the anvil.

  In addition to the above, the sled is moved distally by the firing member. The firing member is configured to contact the sled and push the sled toward the distal end. In one or more alternative embodiments, the sled is coupled to the firing member. A longitudinal slot defined in the cartridge body is configured to receive a firing member. The anvil also includes a slot configured to receive the firing member. The firing member further includes a first cam that engages the first jaw and a second cam that engages the second jaw. As the firing member is advanced distally, the first cam and the second cam can control the distance between the staple cartridge deck and the anvil, ie, the tissue gap. Other embodiments are contemplated where the firing member has only one cam member or no cam member. Such embodiments may include other suitable means for holding the first jaw and the second jaw in place. In any case, the firing member also includes a knife configured to incise the tissue captured between the staple cartridge and the anvil. Desirably, the knife is positioned at least partially proximal to the ramp so that the staple is ejected forward of the knife.

  An end effector 100 of a surgical stapling system is shown in FIG. The end effector 100 includes a frame 190, a cartridge jaw 110, and an anvil 120. The cartridge jaw 110 is fixedly extended from the frame 190. Anvil 120 is movable relative to cartridge jaw 110 between an open or unclamped position and a closed or clamped position (FIG. 1). In an alternative embodiment, the cartridge jaws 110 are movable relative to the anvil 120 between an open or unclamped position and a closed or clamped position. In at least one such embodiment, the anvil 120 extends fixedly from the frame 190.

  The cartridge jaw 110 is configured to receive a staple cartridge such as, for example, a staple cartridge 130. Referring to FIG. 2, the staple cartridge 130 includes a cartridge body 132. The cartridge body 132 includes a deck 133 configured to support patient tissue, a longitudinal slot 135, and a row of six longitudinally extending staple cavities 134 defined within the deck. Longitudinal slot 135 is configured to receive a firing member, such as firing member 270 (FIG. 12). Each staple cavity 134 is configured to receive and removably store staples 140 (FIG. 3) therein. Staple cartridge 130 further includes a staple driver, such as staple driver 180 (FIG. 3A), configured to push staples 140 out of staple cavities 134. Referring to FIGS. 3 and 3A, each staple driver 180 includes a cradle 182 configured to support and / or engage the base or crown 142 of the staple 140. Other staple drivers with two cradles, three cradles, or four cradles for the driver to support and engage two or more staples, for example, are also contemplated.

  In addition to the above, the staple cartridge 130 further includes a sled configured to engage the staple driver 180. More specifically, the sled includes one or more ramps that engage one or more cams defined on the staple driver 180, such as cam 185, for example, and the sled is the staple cartridge 130. Configured to lift the staple driver 180 and staple 140 within the staple cavity 134 when moved distally therethrough. Firing member 270 is configured to move the sled distally from a proximal unfired position to a distal fired position during a staple firing stroke. In at least one case, each staple 140 is completely disposed below the deck 133 of the cartridge body 132 when the staple 140 is in the unfired position. In such a case, the staple leg 144 of the staple 140 does not extend beyond the deck 133 when the staple 140 is in the unfired position. In use, the tips 146 of the staple legs 144 appear above the deck 133 when the staples 140 are fired. With such a configuration, when the staple cartridge 130 is moved relative to the tissue, the possibility that the staple 140 may be caught in the patient's tissue can be reduced.

  In various other cases, in addition to the above, the tip 146 of the staple leg 144 extends beyond the deck 133 when the staple 140 is in the unfired position. Referring primarily to FIG. 2, the cartridge body 132 further includes protrusions 136 that extend above the deck 133, which protrusions at least partially surround the tip 146 when the staple 140 is in the unfired position. It is configured as follows. The length of the staple leg 144 is selected such that the tip 146 is positioned below the top surface of the protrusion 136 when the staple 140 is in the unfired position. The protrusion 136 is also configured to guide the staple leg 144 as the staple 140 is ejected from the staple cavity 134. In some respects, the protrusions 136 extend the staple cavities 134 above the deck 133. Such a configuration allows the use of longer or higher staples while at the same time protecting the staples despite the staples extending above the deck 133.

  In addition to the above, the staple 140 is composed of a wire. The wire has a round or at least substantially round cross section. However, any suitable cross section can be used. For example, a square cross section and / or a cross section having at least one flat side may be used. The wire is made of a metal such as titanium and / or stainless steel. Nevertheless, the wire may be composed of any suitable material, such as plastic.

  Each of the staples 140 is composed of a bent wire that is formed to form a crown portion 142 and a staple leg portion 144 of the staple 140. As will be described in more detail below, the anvil 120 is configured to deform the staple 140 between an unfired configuration (FIG. 3) and a fired configuration. As shown in FIG. 3, the legs 144 of the staples 140 are not parallel to each other when the staples 140 are in an unfired configuration. In such an example, the staple 140 has a substantially V-shaped configuration when the staple 140 is in an unfired configuration. In certain embodiments, staples having legs that are parallel or at least substantially parallel when in an unfired configuration may be utilized. In such an example, the staple has a substantially U-shaped configuration when the staple is in an unfired configuration.

  Referring back to FIG. 2, the staple cartridge 130 further includes a retainer 160 attached to the cartridge body 132. The retainer 160 extends at least partially surrounding the bottom of the cartridge 132 and is configured to prevent the staple 140, staple driver 180, and / or sled from falling from the bottom of the cartridge body 132. The retainer 160 is configured to engage the cartridge body 132 in a snap-fit manner; however, the retainer 160 may be attached to the cartridge body 132 in any suitable manner. Further, the retainer 160 is configured to engage the cartridge jaw 110 in a snap-fit manner to releasably hold the staple cartridge 130 within the cartridge jaw 110. That is, the staple cartridge 130 can be releasably held on the cartridge jaw 110 in any suitable manner.

  In addition to the above, end effector 100 is also configured for use with staple cartridges other than staple cartridge 130, such as, for example, staple cartridge 230 (FIG. 4). In other words, the staple cartridge 230 can be used with the end effector 100 in place of the staple cartridge 130, for example. In one example, the end effector 100 can be used with a staple cartridge 130, and after the staple cartridge 130 is at least partially fired, the staple cartridge 130 is removed from the first jaw 110; The unfired staple cartridge 230 can then be replaced. In various examples, the surgeon may selectively and interchangeably use one or more staple cartridges 130 and one or more staple cartridges 230 in any suitable order.

  Referring to FIG. 4, the staple cartridge 230 includes a cartridge main body 232 and a retainer 260 attached to the cartridge main body 232. The retainer 260 is similar to the retainer 160 in many respects. The retainer 260 is configured to engage the cartridge body 232 in a snap-fit manner; however, the retainer 260 may be attached to the cartridge body 232 in any suitable manner. Further, the retainer 260 is configured to engage the cartridge jaw 110 in a snap-fit manner to releasably hold the staple cartridge 230 within the cartridge jaw 110. That is, the staple cartridge 230 can be releasably held on the cartridge jaw 110 in any suitable manner.

  The cartridge body 232 includes a deck 233 configured to support patient tissue, a longitudinal slot 135, and a row of longitudinally extending staple cavities defined within the deck. The deck 233 includes a first portion on the first side of the longitudinal slot 135 and a second portion on the second side of the longitudinal slot 135. The first portion and the second portion of the deck 233 each have a first or inner longitudinally extending row of staple cavities, a second or intermediate longitudinally extending row of staple cavities, and a third or An outer longitudinally extending row of staple cavities. The first portion of deck 233 includes a first longitudinally extending row that includes staple cavities 234a, a second longitudinally extending row that includes staple cavities 234a, and a third that includes staple cavities 234a ′. Extending in the longitudinal direction. A second portion of deck 233 includes a first longitudinally extending row that includes staple cavities 234a ′, a second longitudinally extending row that includes staple cavities 234a ′, and a second portion that includes staple cavities 234. 3 extending in the longitudinal direction.

  In addition to the above, staple cavity 234a and staple cavity 234a 'are similar in many respects except that they are mirror images of one another. Staple cavities 234a may be referred to as "left" staple cavities, and staple cavities 234a 'may be referred to as "right" staple cavities. Needless to say, left and right are perspective issues, and different nomenclatures can be used, as well as the reverse nomenclature. In addition, any suitable configuration of left staple cavity 234a and right staple cavity 234a 'may be utilized.

  Referring to FIGS. 4, 5, and 14, staples 240 are removably stored within each staple cavity 234a. Referring to FIG. 13, a staple 240 'is removably stored in each staple cavity 234a'. Staple 240 and staple 240 'are similar in many respects except that they are mirror images of each other. Consistent with the nomenclature used above, staples 240 are “left” staples and staples 240 ′ are “right” staples.

  Referring again to FIG. 4, the second portion of deck 233 is a mirror image of the first portion of deck 233. With such a configuration, when the firing member 270 moves distally through the longitudinal slot 135 during the firing stroke, it is formed by a tissue cutting line, ie, a cutting edge 272 defined on the firing member 270. A symmetric staple line is generated with respect to the longitudinal cut. In other embodiments, the second portion of deck 233 is not a mirror image of the first portion of deck 233. With such a configuration, staple lines that are asymmetric with respect to the cutting line are generated in the tissue being stapled.

  Referring primarily to FIGS. 7-10, the staple 240 includes a crown portion 242, a proximal staple leg 244p coupled to the crown portion 242, and a distal leg 244d coupled to the crown portion 242. Yes. More specifically, staple 240 includes a proximal connector 248p that couples proximal staple leg 244p to crown 242 and a distal connector 248d that couples distal staple leg 244d to crown 242. I have. Proximal connector 248p is integrally formed with staple legs 244p and crown 242 and similarly, distal connector 248d is integrally formed with distal staple legs 244d and crown 242. . The staple 240 further includes a driver 246 that is integrally formed with the crown portion 242 and extends from the crown portion. Driver 246 includes a cam surface 245 defined thereon, which is directly engaged by sled 250 of staple cartridge 230 during the staple firing stroke, as shown in FIG. It is configured as follows.

  As can be seen in FIGS. 7-10, the crown 242 and the driver 246 collectively define a higher height than the proximal connector 248p and / or the distal connector 248d. Further, the collective height of the crown portion 242 and the driver 246 defines a dimension that is greater than any cross-sectional width of the staple legs 244p and 244d.

  Similarly, as can be seen in FIGS. 7-10, the proximal leg 244p, the proximal connector 248p, the distal leg 244d, and the distal connector 244d do not extend below the driver 246. In other words, the driver 246 constitutes the bottom of the staple 240. Further, the entire cam surface 245 is below the proximal leg 244p, the proximal connector 248p, the distal leg 244d, and the distal connector 244d. Such a configuration helps to ensure that the thread 250 contacts the driver 246 of the staple 240 and does not contact another portion of the staple 240.

  In addition to the above, referring again to FIG. 13, the staple 240 ′ includes a crown 242 ′, a proximal leg 244p ′ coupled to the crown 242 ′, and a distal leg coupled to the crown 242 ′. A portion 244d 'and a driver 246' formed integrally with the crown portion 242 'and extending from the crown portion. Driver 246 'includes a cam surface 245' defined thereon, which is configured to be directly engaged by sled 250 during the staple firing stroke. Unless indicated otherwise, the teachings presented herein with respect to staple 240 are also applicable to staple 240 '. For the sake of brevity, the discussion dealing with these adaptations may not be specifically described herein.

  Each of the staples 240 is composed of an integral piece of metal such as, for example, titanium and / or stainless steel. Other materials such as plastic can also be utilized. In various examples, the staples 240 are stamped from one or more sheets of material. In at least one example, a continuous flat strip of metal stock is fed to a progression die, which strikes or punches a strip of material and causes the crown portion 242 to staple the staple legs 244p. And 244d with or away from the plane. Instead, the staple legs 244p and 244d are pulled or pushed away from the plane along with the crown 242. In various examples, the progressive die is also configured to form one or more rounded edges on the staple 240, such as on the staple legs 244p and 244d, for example. The progressive die is also configured to cast the tips 246 of the staple legs 244p and 244d in certain instances to remove any excess material from the strip of material. Each of these molding steps may occur at one or more stations in the progressive die and / or in the same molding station in the progressive die, but the configuration ultimately results in, for example, a continuous band rear A piece of staple 240 attached to the (bandolier) will be produced. Staple 240 is removed from the band rear and then inserted into staple cavity 234. In a particular example, a piece of staple 240 is loaded into a loading block where the band rear is then removed from staple 240. Thereafter, the staple 240 is inserted into the staple cavity 234a of the cartridge body 232 using the loading block. In at least one example, the loading block is also configured to receive the staples 240 ′ so that the staples 240 and 240 ′ are loaded into the cartridge body 232 simultaneously.

  In addition to the above, primarily referring to FIG. 7, the driver 246 of each staple 240 is attached to the band rear at a connection point 249 defined on the distal side of the driver 246. Such a configuration, for example, reduces the likelihood that burrs or debris will extend downward from the driver 246 and impede the longitudinal travel of the thread 250. That is, any suitable attachment point can be utilized to hold the staples 240 in the band rear. In addition or alternatively, wire burning, electrical discharge machine (EDM) operation, and / or any other suitable manufacturing process may be utilized to form staples 240. . Further, the staples 240 'can be manufactured utilizing any of the methods described herein, among others.

  Referring to FIGS. 8 and 9, proximal staple leg 244p and distal staple leg 244d of staple 240 define a staple leg plane 241s. In addition to the above, when the staple 240 is disposed in the staple cavity 234a, the proximal staple leg 244p of the staple 240 is located proximal to the distal staple leg 244d. Further, the proximal staple leg 244p and the distal staple leg 244d of the staple 240 are aligned with the firing axis. This firing axis also aligns with the staple legs 244p and 244d of the other staples 240 when the staples 240 are disposed in the longitudinally extending rows of staple cavities 234a. As a result, the staple leg planes 241s of the staples 240 in the rows of longitudinally extending staple cavities 234a are aligned with each other or at least substantially aligned. It should be understood that the staple legs 244p and 244d may have a width or thickness, and the staple leg plane 241s may include that width of the staple legs 244p and / or 244d.

  In addition to the above, referring to FIGS. 4 and 6, the left staple 240 stored in a first inner longitudinally extending row of staple cavities has a staple leg plane 241s of the staple 240 that is more than the drive plane 241c. Is also detachably stored therein so as to be closer to the longitudinal slot 135. Correspondingly, with continued reference to FIGS. 4 and 6, the right staple 240 ′ stored in the second inner longitudinally extending row of staple cavities also has a staple leg plane 241 s of the staple 240 ′. The drive plane 241c is detachably stored therein so as to be closer to the longitudinal slot 135. Similarly, the left staple 240 stored in the first intermediate longitudinally extending row of staple cavities is such that the staple leg plane 241s of the staple 240 is closer to the longitudinal slot 135 than the drive plane 241c. It is detachably stored in it. Similarly, the right staple 240 ′ stored in the second intermediate longitudinally extending row of staple cavities has the staple leg plane 241s of the staple 240 ′ closer to the longitudinal slot 135 than the drive plane 241c. As such, it is detachably stored therein. On the other hand, referring to FIGS. 4 and 6, the right staple 240 ′ housed in the first outer longitudinally extending row of staple cavities has a drive plane 241c of the staple 240 ′ that is more than the staple leg plane 241s. Is also detachably stored therein so as to be closer to the longitudinal slot 135. Similarly, the left staple 240 stored in the second outer longitudinally extending row of staple cavities also causes the drive plane 241c of the staple 240 to be closer to the longitudinal slot 135 than the staple leg plane 241s. In addition, it is detachably stored therein.

  As will be described in more detail below, the staple legs 244p, 244d of the staple 240 comprise the tissue clamped or clamped portions of the staple 240, which portions are staple legs 244p, 244d of the staple 240. Is configured to confine patient tissue within staples 240 when deformed relative to anvil 120. In various examples, proximal staple legs 244p and distal staple legs 244d are formed in the staple leg plane 241s. In other examples, however, one or both of the staple legs 244p and 244d can be deformed out of the staple leg plane 241s.

  In addition to the above, as shown in FIG. 7, the proximal staple leg 244p of the staple 240 is parallel to or at least substantially parallel to the staple leg 244d when the staple 240 is in the unfired configuration. Parallel. As a result, the staple legs 244p, 244d and the crown 242 of the staple 240 form a substantially U-shaped configuration when the staple 240 is in the unfired position. In such a configuration, upward movement of the staple legs 244p and 244d when the staple 240 is ejected from the staple cavity 234a may be easier to control than in other configurations. In various alternative embodiments, referring to FIG. 14, the proximal staple legs 244p and the distal staple legs 244d of the staple 240 are outwardly away from each other and / or in directions that are not parallel to each other. Extend. In at least one such example, staple legs 244p, 244d and crown 242 of staple 240 form a substantially V-shaped configuration when staple 240 is in the unfired position. In such a configuration, the staple legs 244p and 244d of the staple 240 are in contact with and elastically inwardly by the side wall of the staple cavity 234a, which can elastically hold the staple 240 within the staple cavity 234a. Can be energized.

  In addition to the above, the retainer 260 extends at least partially around the bottom of the cartridge 232 to prevent the staples 240, staples 240 ′, and / or sled 250 from falling from the bottom of the cartridge body 232. It is configured.

  Referring primarily to FIG. 10, the driver 246 of the staple 240 includes a drive portion for the staple 240. The longitudinal ramp 255 of the sled 250 is configured to sequentially engage the driver 246 of the staple 240 and slide down below the driver to lift the staple 240 upwardly toward the anvil 120 within the staple cavity 234a. ing. The cam surface 245 of each staple 240 is defined proximally of the driver 246 and includes a point where the thread 250 initiates contact with the staple 240. A driver 246 for each staple 240 is defined in the drive plane 241c, and the drive plane is aligned or at least substantially aligned with the longitudinal ramp 255. A cam surface 245 is also defined in the drive plane 241c. It should be understood that the cam surface 245 and / or driver 246 may have a width or thickness, and the drive plane 241c may include the cam surface 245 and / or its width of the driver 246.

  Referring again to FIGS. 8 and 9, connectors 248p and 248p separate staple legs 244p and 244d from crown portion 242 of staple 240, respectively. As shown in FIGS. 8 and 9, the drive plane 241 c of the staple 240 is offset laterally from the staple leg plane 241 s of the staple 240. Similarly, as shown in FIGS. 8 and 9, the drive plane 241 c of the staple 240 is parallel or at least substantially parallel to the staple leg plane 241 s of the staple 240. In such an example, the drive planes 241c of the longitudinally extending rows of staples 240 are aligned with one another along the longitudinal drive axis. The longitudinal drive axis is parallel to and adjacent to the longitudinal firing axis aligned with the staple leg plane 241s described above.

  Referring again to FIGS. 8-10, the longitudinal ramp 255 does not engage the proximal connector 248p or the distal connector of the staple 240. Similarly, the longitudinal ramp 255 does not engage the staple legs 244p and 244d of the staple 240. Further, no portion of sled 250 engages proximal connector 248p, proximal staple leg 244p, distal connector 248d, and distal staple leg 244d of staple 240. Instead, the longitudinal ramp 255 engages directly with the cam surface 245 of the staple 240 as the sled 250 is moved distally during the firing stroke. As the sled 250 is moved distally, the longitudinal ramp 255 slides down the cam surface 245 and continues to move the staple 240 into the anvil 120 between the unfired position (FIG. 11) and the fired position (FIG. 12). Lift upwards. In other words, the staple 240 slides the longitudinal ramp 255 upward toward the firing position within the staple cavity 234a as shown in FIG.

  In addition to the above, referring primarily to FIG. 10, the drive surface 245 of the staple 240 does not extend to the proximal connector 248p. Driver 246 includes a notch or relief 247 that separates drive surface 245 from proximal connector 248p. In various examples, the notch 247 is defined in the drive plane 241c. In at least one example, notch 247 extends to proximal connector 248p. The notch 247 ensures that the sled 250 contacts the driver 246 of the staple 240, i.e., the drive plane 241c of the staple 240, and does not contact the proximal connector 248p and / or the proximal leg 244p. It is configured. Notch 247 also creates a clear depiction between driver 246 and proximal connector 248p so that cam surface 245 is not twisted out of drive plane 241c. Further, the notch 247 separates the drive plane 241c from the vertical plane that includes the proximal staple legs 244p.

  As above, the drive plane 245 does not extend to the distal connector 248d.

  In addition to the above, the drive plane 245 of the staple 240 extends at an angle that matches or at least substantially matches the angle of the longitudinal ramp 255 of the sled 250. That is, any suitable angle can be used.

  In at least one example, in addition to the above, each staple 240 is fully disposed below the deck 233 of the cartridge body 232 when the staple 240 is in the unfired position. In such an example, the staple legs 244 of the staple 240 do not extend beyond the deck 233 when the staple 240 is in the unfired position. In use, the tips 246 of the staple legs 244 appear above the deck 233 when the staples 240 are fired. With such a configuration, when the staple cartridge 230 is moved with respect to the tissue, the possibility that the staple 240 may get caught in the patient's tissue can be reduced.

  In various examples, in addition to the above, the tips 246 of the staple legs 244p and / or 244d extend beyond the deck 233 when the staples 240 are in the unfired position. Referring primarily to FIGS. 4 and 6, the cartridge body 232 further includes protrusions 236 that extend above the deck 233, which protrusions 246 at least partially when the staple 240 is in the unfired position. It is comprised so that it may surround. The lengths of the staple legs 244p and 244d are selected such that the tip 246 is positioned below the top surface of the protrusion 236 when the staple 240 is in the unfired position. In some respects, the protrusion 236 extends the staple cavity 234 above the deck 233. Such a configuration may allow the use of longer or higher staples while at the same time allowing protection of the staples despite the staples extending above the deck 233. The protrusion 236 is also configured to guide the staple legs 244 as the staple 240 is ejected from the staple cavity 234.

  In addition to the above, the staple 240 reaches a fully fired configuration when the top surface 253 of the longitudinal ramp 255 passes below the bottom surface of the staple 240. Referring now to FIG. 12, the staple 240 has substantially reached the top surface 253 of the longitudinal ramp 255 and thus has substantially reached the fully fired configuration. When the top surface 253 moves distally relative to the deformed staple 240 and becomes disengaged from the deformed staple 240, the elastic reaction forces and / or potential energy stored in the deformed staple 240 A portion of the deformed staple 240 can again be pushed into the ejected staple cavity 234a.

  Referring again to FIGS. 11 and 12, the anvil 120 includes a forming pocket configured to deform the staples 240 and 240 '. Each of the molding pockets is, for example, a proximal molding cup 124p configured to receive the proximal staple legs 244p of the staple 240 and a distal mold configured to receive the distal staple legs 244d of the staple 240. And a cup 124d. The proximal molded cup 124p is configured to deform the proximal staple leg 244p inward toward the distal staple leg 244d. Similarly, the distal molded cup 124d is configured to deform the distal staple leg 244d inward toward the proximal staple leg 244p. Other embodiments are contemplated where one or both of the staple legs 244p and 244d are bent away from each other outward and / or in any other suitable direction. Referring again to FIG. 12, the staples 240 and 240 ′ have been deformed by the anvil 120 into a B-shaped configuration, however, the anvil 120 has deformed the staples 240 and 240 ′ into any suitable configuration. You may be comprised so that it may make.

  As discussed above, the end effector 100 can be used with the staple cartridge 100 or alternatively with the staple cartridge 200. As a result, the anvil 120 is configured to deform the staples 140 of the staple cartridge 100 and in addition to the staples 240, 240 ′ of the staple cartridge 200. In other words, for example, the molding pockets defined in the anvil 120 are each configured to deform a staple 140 made from a bent wire and a staple 240 or staple 240 'punched from a flat sheet of material. Has been. For example, referring primarily to FIG. 6, the proximal forming cup 124 p of the forming pocket is configured to deform the proximal staple leg 144 of the staple 140 and the proximal staple leg 244 p of the staple 240. The proximal forming cup 124p of the forming pocket is also configured to deform the proximal staple leg 244p 'when the staple 240' is aligned with the forming pocket instead of the staple 240. Similar to the above, the distal forming cup 124d of the forming pocket is configured to deform the distal staple leg 144 of the staple 140 and the distal staple leg 244d of the staple 240. Similarly, the distal forming cup 124d of the forming pocket is also configured to deform the distal staple leg 244d 'when the staple 240' is aligned with the forming pocket instead of the staple 240.

  In addition to the above, the staple cavities 134 of the staple cartridge 130 and the staple cavities 234a of the staple cartridge 230 depend on which staple cartridge the tip 140 of the staple 140 and the tip 246 of the staple 240 are attached to the end effector 100. It can be aligned with the molding pocket of the anvil 120 to strike the same point or target in the molding cups 124p and 124d. It should be understood that tip 146 and tip 246 may not actually strike the same target in molding cups 124p and 124d, for example due to variations in tissue composition. That is, the forming cavity of the anvil 120 is configured to guide the leg portion 144 of the staple 140 and the leg portions 244p, 244d of the staple 240 to a desired alignment state. For this purpose, the proximal molded cup 124p includes a guide wall 126p, the distal molded cup 124d includes a guide wall 126d, which guides the legs of the staples 140, 240, and 240 ′ to the desired configuration. It is configured to guide and mold.

  Referring again to FIG. 7, the staple 240 includes a tissue engaging surface 243 defined on the top surface of the crown 242. The surface 243 of the staple 240 is configured to support and / or apply pressure to the tissue captured within the staple 240 as the staple 240 is molded into the firing configuration. Referring now to FIG. 11, the surface 243 of the staple 240 is located well below the deck 233 of the cartridge body 232 when the staple 240 is in the unfired position. Referring now to FIG. 12, when the staple 240 is moved to the firing position, the surface 243 appears at least partially above the deck 233. In other words, the sled 250 at least partially overdrives the staple 240. In such cases, the surface 243 of the staple 240 may abut and apply pressure to the tissue when the staple 240 is deformed. In some cases, only a portion of the surface 243 is overdriven above the deck 233 when the staple 240 is in the fully fired position. In other cases, the entire surface 243 is overdriven above the deck 233 when the staple 240 is in the fully fired position. Such a configuration allows a substantial amount of clamping pressure to be applied to the tissue, thereby reducing bleeding from the tissue.

  In various examples, in addition to the above, the driver 246 of the staple 240 is still at least partially below the deck 233 when the surface 243 of the staple 240 is overdriven above the deck 233. In some cases, the staples 240 are configured such that the driver 246 does not appear above the deck 233 regardless of the degree to which the surface 243 is overdriven above the deck 233. In such a case, the entire driver 246 remains below the deck 233 during the staple firing stroke. In at least one example, the cam surface 245 of the staple 240 does not appear above the deck 233 when the staple 240 is overdriven. In various examples, the top surface 253 of the longitudinal ramp 255 does not extend above the deck 233. This means that the sled 250 does not drive the entire staple 240 above the deck 233 during the staple firing stroke.

  In addition to the above, it should be understood that the protrusion 236 extends above the deck 233. As shown in FIG. 12, the sled 250 is configured to at least partially overdrive the surface 243 of the staple 240 above the protrusion 236. In such an example, the surface 243 rises at least partially above the protrusion 236 when the staple 240 is moved to the fully fired position. In some cases, only a portion of the surface 243 is overdriven above the protrusion 246 when the staple 240 is in the fully fired position. In other cases, the entire surface 243 is overdriven above the protrusion 246 when the staple 240 is in the fully fired position. Such a configuration allows a substantial amount of clamping pressure to be applied to the tissue, thereby reducing bleeding from the tissue.

  In addition to the above, the tissue engaging surface 243 may directly engage or contact tissue. In other cases, for example, a piece of buttress material and / or a tissue thickness compensator may be disposed on the deck 233 of the staple cartridge 230 and the tissue engaging surface 243 may be on the supplemental material. You may engage or contact directly. References disclosing ancillary materials are incorporated by reference elsewhere in this application.

  Referring again to FIG. 7, the tissue engaging surface 243 includes a flat portion, a first inclined portion on the first side of the flat portion, and a second inclined portion on the second side of the flat portion; It has. With such a configuration, pressure can be applied to the tissue captured in the staple 240 from three directions. That is, the tissue engaging surface 243 may comprise any suitable configuration, such as, for example, a completely flat configuration or a rounded configuration.

  As discussed above, referring again to FIG. 6, staple cartridges 130 and 230 may be used with end effector 100 in a selectable and replaceable manner. Similarly, as discussed above, staple cartridges 130 and 230 are removably attachable to jaw 110. In various alternative embodiments, the staple cartridges 130 and 230 each have a full jaw that can be attached to and removed from the frame 190 of the end effector 110. In such a case, the clinician, for example, removes the entire staple cartridge jaw from the end effector 110 and another full staple cartridge jaw, i.e., the type of staples and / Or it can be replaced with one having a pattern of staples.

  In addition to the above, it should be understood that FIG. 6 is intended to show that end effector 100 can be used with staple cartridge 130 and staple cartridge 230. Although both staple cartridge 130 and staple cartridge 230 are shown in FIG. 6, it should be understood that staple cartridge 130 and staple cartridge 230 are not used simultaneously within the same end effector 100. That is, for example, various embodiments are contemplated in which the staple cartridge utilizes wire staples and in addition, staples formed from one or more sheet materials. In at least one embodiment, the staple cartridge includes, for example, staples 140 and 240 detachably stored therein. For example, other embodiments are contemplated where the staple cartridge comprises staples 140, staples 240, and staples 240 '.

  Referring to FIG. 20, in addition to the above, the staple cartridge 430 includes a cartridge body 432 that includes a deck 433 and a longitudinal slot 135 defined therein. The longitudinal slot 135 defines a longitudinal slot axis 139 that extends through its center. The staple cartridge 430 has a first or inner longitudinally extending row of cavities 434a, a second or intermediate longitudinally extending row of staple cavities 434b, and a third on one side of the longitudinal slot 135. And an outer longitudinally extending row of staple cavities 434c. Staple cartridge 430 also has a first or inner longitudinally extending row of cavities 434a 'and a second or intermediate longitudinally extending staple cavity 434b' on the other side of longitudinal slot 135. And a third or outer longitudinally extending row of staple cavities 434c '. Staple cavities 434a, 434a ', 434b, and 434b' are similar in many respects to left staple cavity 234a (FIGS. 4 and 6). Staple cavities 434c and 434c 'are similar in many respects to left staple cavity 134 (FIGS. 2 and 6). The staple 240 is detachably stored in the staple cavities 434a, 434a ', 434b, and 434b'. The staple 140 is detachably stored in the staple cavities 434c and 434c '.

  Referring to FIG. 21, the staple cartridge 430 further includes a sled 450 configured to eject the staples 140 and 240 from the cartridge body 432. The sled 450 directly engages the longitudinal ramp 455a configured to directly engage the staple 240 stored in the staple cavity 434a and the staple 240 stored in the staple cavity 434a ′. A longitudinal ramp 455a ′ configured in such a manner, a longitudinal ramp 455b configured to directly engage the staple 240 stored in the staple cavity 434b, and a staple stored in the staple cavity 434b ′. And a longitudinal ramp 455b ′ configured to engage directly with 240. The sled 450 further includes a longitudinal ramp 455c configured to eject the staple 140 from the staple cavity 434c, and a longitudinal ramp 455c ′ configured to eject the staple 140 from the staple cavity 434c ′. . More specifically, the staple cartridge 430 is stored in the staple cavity 434c ′ with a row of staple drivers configured to support and / or engage the staples 140 stored in the staple cavity 434c. A row of staple drivers configured to support and / or engage the staples 140 formed, and when the sled 450 is advanced distally, the longitudinal direction of the sled 450 The ramps 455c and 455c ′ engage the staple driver to lift the staple 140 upward within the staple cavities 434c and 434c ′ and deform the staple 140 relative to the anvil disposed on the opposite side of the staple cartridge 430. These staple drivers may be similar in many respects, for example, to the staple driver shown in FIG. 3A.

  In addition to the above, the staple cavity 434a is disposed along the longitudinal axis 437a, the staple cavity 434b is disposed along the longitudinal axis 437b, and the staple cavity 434c is disposed along the longitudinal axis 437c. Similarly, staple cavities 434a ′ are disposed along longitudinal axis 437a ′, staple cavities 434b ′ are disposed along longitudinal axis 437b ′, and staple cavities 434c ′ are disposed along longitudinal axis 437c ′. ing. The distance between the longitudinal axis 437a and the longitudinal slot axis 139 is shorter than the distance between the longitudinal axis 437a 'and the longitudinal slot axis 139. As a result, the longitudinal axis 437a 'is staggered or offset laterally compared to the longitudinal axis 437a. Similarly, the distance between the longitudinally extending rows of staple cavities 434 a and the longitudinal slots 135 is shorter than the distance between the longitudinally extending staple cavities 434 a ′ and the longitudinal slots 135. In addition, the distance between the longitudinal axis 437b and the longitudinal slot axis 139 is shorter than the distance between the longitudinal axis 437b 'and the longitudinal slot axis 139. As a result, the longitudinal axis 437b 'is staggered or offset laterally compared to the longitudinal axis 437b. Similarly, the distance between the longitudinally extending rows of staple cavities 434 b and the longitudinal slots 135 is shorter than the distance between the longitudinally extending rows of staple cavities 434 b ′ and the longitudinal slots 135. For comparison, the longitudinal axis 437c and the longitudinal axis 437c 'are equidistant from the longitudinal slot axis 139. Correspondingly, the longitudinally extending rows of staple cavities 343 c and the longitudinally extending rows of staple cavities 343 c ′ are equidistant from the longitudinal slot 135.

  The longitudinally extending rows of staple cavities defined within the staple cartridge 430 are not evenly spaced. In many respects, the distance between the longitudinally extending rows is different. As can be seen in FIG. 20, the spacing between the rows of longitudinally extending staple cavities 434a, 434b, and 434c on one side of the longitudinal slot 135 is the longitudinally extending staple cavity on the other side of the longitudinal slot 135. This is different from the interval between the columns 434a ′, 434b ′, and 434c ′.

  In addition to the above, the longitudinal axes 437a, 437a ', 437b, 437b', 437c, and 437c 'include drive axes. These drive axes are optionally aligned with the drive portion of the staple 240 and the cam surface of the staple driver that supports the staple 140. The longitudinal ramp of sled 450 is aligned with these drive axes. For example, referring to FIGS. 20 and 21, the longitudinal ramp 455a of the sled 450 is aligned with the longitudinal axis 437a. Similarly, longitudinal ramp 455b is aligned with longitudinal axis 437b and longitudinal ramp 455c is aligned with longitudinal axis 437c. Also, the longitudinal ramp 455a 'is aligned with the longitudinal axis 437a', the longitudinal ramp 455b 'is aligned with the longitudinal axis 437b', and the longitudinal ramp 455c 'is aligned with the longitudinal axis 437c'. For this purpose, the longitudinal ramp 455a and the longitudinal axis 437a are separated from the longitudinal slot axis 139 by a distance 457a, and the longitudinal ramp 455b and the longitudinal axis 437b are separated from the longitudinal slot axis 139 by a distance 457b; Longitudinal ramp 455c and longitudinal axis 437c are separated from longitudinal slot axis 139 by a distance 457c. Similarly, longitudinal ramp 455a ′ and longitudinal axis 437a ′ are separated from longitudinal slot axis 139 by a distance 457a ′, and longitudinal ramp 455b ′ and longitudinal axis 437b ′ are longitudinal slot axis 139 by distance 457b ′. The longitudinal ramp 455c ′ and the longitudinal axis 437c ′ are separated from the longitudinal slot axis 139 by a distance 457c ′.

  As can be seen in FIG. 21, the distances 457a, 457a ', 457b, and 457b' are not equal. These are all different. As a result, the rails of the sled 450 are asymmetrically spaced.
