A surgical stapling system can comprise 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 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 envisioned. The second jaw includes an anvil configured to deform 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 includes an articulation joint configured to allow the end effector to rotate or articulate with respect to the shaft. The end effector is rotatable about an articulation axis that extends through the articulation joint. Other embodiments are also envisioned that do not include an articulation joint.

The staple cartridge has 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 a first side of the tissue to be stapled and the anvil is positioned on a second side of the tissue. The anvil is moved toward the staple cartridge to compress and clamp tissue against the deck. Staples removably stored within the cartridge body can then be deployed into tissue. The cartridge body includes a staple cavity defined therein, and staples are removably stored within the staple cavities. The staple cavities are arranged in six longitudinal rows. Three rows of staple cavities are positioned on a first side of the longitudinal slot and three rows of staple cavities are positioned on a second side of the longitudinal slot. Other arrangements of staple cavities and staples may also be possible.

The staples are supported by staple drivers within 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 cavities. The driver is retained within the cartridge body by a retainer extending around the bottom of the cartridge body and includes a resilient member configured to grip the cartridge body and retain the retainer against the cartridge body. . The drivers are movable between their unfired position and their fired position 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 slides under the driver and includes a plurality of ramps configured to lift the driver, with staples supported thereon, toward the anvil.

In addition to the above, the sled is moved distally by the firing member. A 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 within the cartridge body is configured to receive the firing member. The anvil also includes a slot configured to receive the firing member. The firing member further comprises a first cam engaging the first jaw and a second cam engaging the second jaw. In advancing the firing member distally, the first cam and the second cam can control the distance between the deck of the staple cartridge and the anvil, ie, the tissue gap. Other embodiments are contemplated in which the firing member has only one cam member or no cam members. Such embodiments may include other suitable means for holding the first and second jaws in place. In any event, the firing member also includes a knife configured to cut tissue captured between the staple cartridge and the anvil. Desirably, the knife is positioned at least partially proximal to the ramp so that the staples are ejected forward of the knife.

An end effector 100 of a surgical stapling system is shown in FIG. End effector 100 includes frame 190 , cartridge jaw 110 and anvil 120 . Cartridge jaw 110 extends fixedly from 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 alternative embodiments, 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, anvil 120 extends fixedly from frame 190 .

Cartridge jaws 110 are configured to receive a staple cartridge, such as staple cartridge 130, for example. Referring to FIG. 2, staple cartridge 130 includes cartridge body 132 . 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 in the deck. Longitudinal slot 135 is configured to receive a firing member, such as, for example, firing member 270 (FIG. 12). Staple cavities 134 are each configured to receive and removably store a staple 140 (FIG. 3) therein. Staple cartridge 130 further includes a staple driver, such as staple driver 180 (FIG. 3A), configured to drive staples 140 out of staple cavities 134 . 3 and 3A, staple drivers 180 each include a cradle 182 configured to support and/or engage base or crown portion 142 of staple 140 . Other staple drivers are contemplated in which the driver includes, for example, two cradles, three cradles, or four cradles for supporting and engaging two or more staples.

In addition to the above, staple cartridge 130 further includes a thread configured to engage staple driver 180 . More specifically, the sled includes one or more ramps that engage one or more cams defined on staple driver 180 , such as cams 185 , and the sled engages staple cartridge 130 . configured to lift staple driver 180 and staple 140 within staple cavity 134 when moved distally through. Firing member 270 is configured to distally move the sled from a proximal unfired position to a distal fired position during the staple firing stroke. In at least one case, staples 140 are each fully disposed below deck 133 of cartridge body 132 when staples 140 are in the unfired position. In such cases, staple legs 144 of staple 140 do not extend beyond deck 133 when staple 140 is in the unfired position. In use, tips 146 of staple legs 144 emerge above deck 133 when staples 140 are fired. Such a configuration can reduce the likelihood that the staples 140 will catch on the patient's tissue when the staple cartridge 130 is moved relative to the tissue.

In various other instances, further to the above, tips 146 of staple legs 144 extend beyond deck 133 when staples 140 are in the unfired position. Referring primarily to FIG. 2, cartridge body 132 further includes protrusions 136 extending above deck 133 that at least partially surround tips 146 when staples 140 are in the unfired position. is configured as The length of staple legs 144 is selected such that tip 146 is positioned below the top surface of projection 136 when staple 140 is in the unfired position. Protrusions 136 are also configured to guide staple legs 144 as staples 140 are ejected from staple cavities 134 . In some respects, protrusions 136 extend staple cavities 134 above deck 133 . Such a configuration allows the use of longer or taller staples while still protecting the staples even though they extend above deck 133 .

In addition to the above, the staple 140 is constructed from wire. The wire has a round or at least substantially round cross-section. However, any suitable cross-section may be used. For example, square cross-sections and/or cross-sections with at least one flat side may be used. The wire is made of metal, for example titanium and/or stainless steel. That said, the wire may be constructed from any suitable material, such as plastic for example.

Staples 140 each comprise a curved wire that is formed to define a crown portion 142 and staple legs 144 of staple 140 . Anvil 120 is configured to deform staples 140 between an unfired configuration (FIG. 3) and a fired configuration, as described in greater detail below. As shown in FIG. 3, legs 144 of staple 140 are not parallel to each other when staple 140 is in the unfired configuration. In such examples, staple 140 comprises a substantially V-shaped configuration when staple 140 is in the unfired configuration. In certain embodiments, staples having parallel or at least substantially parallel legs when in the unfired configuration may be utilized. In such examples, the staple comprises a substantially U-shaped configuration when the staple is in the unfired configuration.

Referring again to FIG. 2, staple cartridge 130 further includes retainer 160 attached to cartridge body 132 . Retainer 160 extends at least partially around the bottom of cartridge 132 and is configured to prevent staples 140 , staple drivers 180 and/or threads from falling out of the bottom of cartridge body 132 . Retainer 160 is configured to engage cartridge body 132 in a snap-fit manner; however, retainer 160 may be attached to cartridge body 132 in any suitable manner. Further, retainer 160 is configured to engage cartridge jaws 110 in a snap-fit manner to releasably retain staple cartridge 130 within cartridge jaws 110 . That is, staple cartridge 130 may be releasably retained in cartridge jaws 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). Stated another way, staple cartridge 230 may be used with end effector 100 in place of 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 has been at least partially fired, the staple cartridge 130 is removed from the first jaw 110 and An unfired staple cartridge 230 can then be replaced. In various examples, a 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, staple cartridge 230 includes cartridge body 232 and retainer 260 attached to cartridge body 232 . Retainer 260 is similar in many respects to retainer 160 . Retainer 260 is configured to engage cartridge body 232 in a snap-fit manner; however, retainer 260 may be attached to cartridge body 232 in any suitable manner. Further, retainer 260 is configured to engage cartridge jaws 110 in a snap-fit manner to releasably retain staple cartridge 230 within cartridge jaws 110 . That is, staple cartridge 230 may be releasably retained in cartridge jaws 110 in any suitable manner.

Cartridge body 232 includes a deck 233 configured to support patient tissue, a longitudinal slot 135, and a longitudinally extending row of staple cavities defined in the deck. Deck 233 has a first portion on a first side of longitudinal slot 135 and a second portion on a second side of longitudinal slot 135 . The first and second portions of 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 inner row of staple cavities. and an outer longitudinally extending row of staple cavities. A first portion of deck 233 includes a first longitudinally extending row including staple cavities 234a, a second longitudinally extending row including staple cavities 234a, and a third longitudinal row including staple cavities 234a'. and a longitudinally extending row of . A second portion of deck 233 includes a first longitudinally extending row including staple cavities 234a′, a second longitudinally extending row including staple cavities 234a′, and a second longitudinal row including staple cavities 234a′. 3 longitudinally extending rows.

In addition to the above, staple cavities 234a and 234a' are similar in many respects, except that they are mirror images of each other. Staple cavity 234a may be referred to as the "left" staple cavity and staple cavity 234a' may be referred to as the "right" staple cavity. Of course, left and right is a matter of perspective, and different nomenclature, even reversed nomenclature, may be utilized. Additionally, any suitable configuration of left staple cavity 234a and right staple cavity 234a' may be utilized.

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

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, a tissue cutting line, i.e., a cutting edge 272 defined on firing member 270 as firing member 270 moves distally through longitudinal slot 135 during the firing stroke, is formed by A symmetrical staple line is produced for longitudinal cuts. In other embodiments, the second portion of deck 233 is not a mirror image of the first portion of deck 233 . Such a configuration creates a staple line in the tissue being stapled that is asymmetrical with respect to the cut line.

Referring primarily to FIGS. 7-10, staple 240 includes crown 242, proximal staple leg 244p connected to crown 242, and distal leg 244d connected to crown 242. there is More specifically, staple 240 includes a proximal connector 248p connecting proximal staple leg 244p to crown 242 and a distal connector 248d connecting 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. . Staple 240 further includes a driver 246 integrally formed with and extending from crown portion 242 . Driver 246 has a camming surface 245 defined thereon which is directly engaged by sled 250 of staple cartridge 230 during the staple firing stroke, as shown in FIG. is configured as

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

As can also be seen in FIGS. 7-10, proximal leg 244p, proximal connector 248p, distal leg 244d, and distal connector 244d do not extend below driver 246. FIG. In other words, driver 246 forms the bottom of staple 240 . Further, the entirety of camming surface 245 underlies proximal leg 244p, proximal connector 248p, distal leg 244d, and distal connector 244d. Such a configuration helps ensure that sled 250 contacts driver 246 of staple 240 and does not contact another portion of staple 240 .

In addition to the above, referring again to FIG. 13, the staple 240' includes a crown portion 242', a proximal leg portion 244p' connected to the crown portion 242', and a distal leg portion connected to the crown portion 242'. It includes a portion 244d' and a driver 246' integrally formed with and extending from the crown portion 242'. Driver 246' has a cam surface 245' defined thereon configured to be directly engaged by sled 250 during the staple firing stroke. Unless otherwise stated, 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 addressed herein.

Staples 240 are each constructed from an integral piece of metal, such as, for example, titanium and/or stainless steel. Other materials such as plastics may also be used. In various examples, 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 the strip of material, forming crowns 242 into staple legs 244p. and 244d to pull or push away from the plane. Instead, staple legs 244p and 244d are pulled or pushed away from the plane along with crown 242. FIG. In various examples, the progressive die is also configured to form one or more rounded edges on staple 240, eg, on staple legs 244p and 244d. The progressive die is also configured to cast tips 246 of staple legs 244p and 244d in certain examples and to remove any excess material from the strip of material. Each of these forming steps can occur at one or more stations within the progressive die and/or within the same forming station within the progressive die, but the configuration ultimately results in, for example, a continuous bandolier. A piece of staple 240 attached to a bandolier will be produced. Staples 240 are removed from the bandolier and then inserted into staple cavities 234 . In a particular example, a piece of staple 240 is loaded into a loading block where the bandolier is then removed from staple 240 . A loading block is then used to insert staples 240 into staple cavities 234 a of cartridge body 232 . In at least one example, loading block is also configured to receive staples 240 ′ such that staples 240 and 240 ′ are simultaneously loaded into cartridge body 232 .

In addition to the above, referring primarily to FIG. 7, the driver 246 of each staple 240 is attached to the bandolier at a connection point 249 defined distally of the driver 246 . Such a configuration reduces the likelihood that, for example, burrs or tags may extend downward from driver 246 and interfere with the longitudinal travel of sled 250 . That is, any suitable attachment point may be utilized to hold the staple 240 to the bandolier. Additionally or alternatively, wire burning, or electrical discharge machining (EDM) operations, and/or any other suitable manufacturing process may be utilized to form staples 240. . Additionally, staples 240' may be manufactured utilizing any of the methods described herein, among others.

8 and 9, proximal staple leg 244p and distal staple leg 244d of staple 240 define staple leg plane 241s. In addition to the above, proximal staple legs 244p of staples 240 are proximal to distal staple legs 244d when staples 240 are positioned within staple cavities 234a. Additionally, proximal staple leg 244p and distal staple leg 244d of staple 240 are aligned with the firing axis. This firing axis also aligns with staple legs 244p and 244d of other staples 240 when the staples 240 are positioned within the rows of longitudinally extending staple cavities 234a. As a result, the staple leg planes 241s of the staples 240 within the longitudinally extending row of staple cavities 234a are aligned, or at least substantially aligned, with each other. It should be appreciated that staple legs 244p and 244d may comprise a width or thickness, and staple leg plane 241s may include the width of staple legs 244p and/or 244d.

In addition to the above, and with reference to FIGS. 4 and 6, the left staple 240 stored within the first inner longitudinally extending row of staple cavities has a staple leg plane 241s of the staple 240 extending from the drive plane 241c. are removably 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 within the second inner longitudinally extending row of staple cavities also has a staple leg plane 241s of the staple 240'. It is removably stored therein so as to be closer to longitudinal slot 135 than drive plane 241c. Similarly, the left staple 240 stored in the first intermediate longitudinally extending row of staple cavities is positioned 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 longitudinal 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 removably stored therein. On the other hand, referring to FIGS. 4 and 6, the right staple 240' stored in the first outer longitudinally extending row of staple cavities is such that the drive plane 241c of the staple 240' extends further than the staple leg plane 241s. are removably 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 is also arranged such that the drive plane 241c of the staple 240 is closer to the longitudinal slot 135 than the staple leg plane 241s. and is detachably stored therein.

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

In addition to the above, as shown in FIG. 7, proximal staple legs 244p of staples 240 are parallel or at least substantially parallel to staple legs 244d when staples 240 are in the unfired configuration. parallel. As a result, staple legs 244p, 244d and crown 242 of staple 240 form a substantially U-shaped configuration when staple 240 is in the unfired position. In such a configuration, the upward movement of staple legs 244p and 244d as staples 240 are being ejected from staple cavity 234a may be easier to control than in other configurations. In various alternative embodiments, referring to FIG. 14, proximal staple legs 244p and distal staple legs 244d of staple 240 are directed 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, staple legs 244p and 244d of staple 240 contact and are resiliently inwardly retracted by the sidewalls of staple cavity 234a, which may retain staple 240 resiliently within staple cavity 234a. can be activated.

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

Referring primarily to FIG. 10, staple 240 driver 246 comprises the drive portion of staple 240 . Longitudinal ramps 255 of sled 250 are configured to sequentially engage and slide under driver 246 of staple 240 to lift staple 240 upward toward anvil 120 within staple cavity 234a. ing. Camming surface 245 of each staple 240 is defined proximally of driver 246 and includes the point at which sled 250 initiates contact with staple 240 . A driver 246 of each staple 240 is defined within a drive plane 241 c that is aligned or at least substantially aligned with longitudinal ramp 255 . A cam surface 245 is also defined within drive plane 241c. It should be appreciated that cam surface 245 and/or driver 246 may have a width or thickness, and drive plane 241c may include the width of cam surface 245 and/or driver 246 .

8 and 9, connectors 248p and 248p separate staple legs 244p and 244d from crown 242 of staple 240, respectively. As shown in FIGS. 8 and 9 , drive plane 241 c of staple 240 is laterally offset from staple leg plane 241 s of staple 240 . 8 and 9, drive plane 241c of staple 240 is parallel, or at least substantially parallel, to staple leg plane 241s of staple 240. As shown in FIG. In such instances, 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 staple leg plane 241s described above.

Referring again to FIGS. 8-10, longitudinal ramp 255 does not engage proximal connector 248p or distal connector of staple 240. FIG. Similarly, longitudinal ramp 255 does not engage staple legs 244 p and 244 d of 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. FIG. Instead, longitudinal ramp 255 directly engages cam surface 245 of staple 240 as sled 250 is moved distally during the firing stroke. As sled 250 is moved distally, longitudinal ramp 255 slides under cam surface 245, continuing to force staples 240 onto anvil 120 between an unfired position (FIG. 11) and a fired position (FIG. 12). and lift upwards. In other words, staple 240 slides up longitudinal ramp 255 toward firing position within staple cavity 234a, as shown in FIG.

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

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

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

In at least one example, further to the above, each staple 240 is fully disposed below deck 233 of cartridge body 232 when staple 240 is in the unfired position. In such instances, staple legs 244 of staple 240 do not extend beyond deck 233 when staple 240 is in the unfired position. In use, tips 246 of staple legs 244 emerge above deck 233 when staples 240 are being fired. Such a configuration can reduce the likelihood that the staples 240 will catch on the patient's tissue when the staple cartridge 230 is moved relative to the tissue.

In various examples, further to the above, tips 246 of staple legs 244p and/or 244d extend beyond deck 233 when staples 240 are in the unfired position. Referring primarily to FIGS. 4 and 6, cartridge body 232 further includes projections 236 extending above deck 233 that at least partially extend tips 246 when staples 240 are in the unfired position. It is configured to be surrounded by The lengths of staple legs 244p and 244d are selected such that tip 246 is positioned below the upper surface of projection 236 when staple 240 is in the unfired position. In some respects, protrusions 236 extend staple cavities 234 above deck 233 . Such a configuration may allow the use of longer or taller staples while protecting the staples even though they extend above deck 233 . Protrusions 236 are also configured to guide staple legs 244 as staples 240 are ejected from staple cavities 234 .

Further to the above, staple 240 reaches a fully fired configuration when top surface 253 of longitudinal ramp 255 passes below the bottom surface of staple 240 . Referring now to FIG. 12, staple 240 has nearly reached top surface 253 of longitudinal ramp 255 and thus has nearly reached the fully fired configuration. As top surface 253 moves distally relative to deformed staple 240 and disengages from deformed staple 240, elastic reaction forces and/or potential energy stored in deformed staple 240 may , a portion of the deformed staple 240 can be forced back into the ejected staple cavity 234a.

Referring again to FIGS. 11 and 12, anvil 120 includes forming pockets configured to deform staples 240 and 240'. The forming pockets are, for example, proximal forming cups 124p configured to receive proximal staple legs 244p of staples 240 and distal forming cups 124p configured to receive distal staple legs 244d of staples 240, respectively. and a cup 124d. Proximal forming cup 124p is configured to deform proximal staple legs 244p inward toward distal staple legs 244d. Similarly, distal shaping cup 124d is configured to deform distal staple legs 244d inward toward proximal staple legs 244p. Other embodiments are also contemplated in which one or both of staple legs 244p and 244d are folded outwardly away from each other and/or in any other suitable direction. Referring again to FIG. 12, staples 240 and 240' have been transformed into a B-shaped configuration by anvil 120, however, anvil 120 may transform staples 240 and 240' into any suitable configuration. may be configured to allow

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

In addition to the above, staple cavities 134 of staple cartridge 130 and staple cavities 234a of staple cartridge 230 may be configured such that the tips 146 of staples 140 and the tips 246 of staples 240 may be adjusted depending on which staple cartridge is attached to end effector 100. Alignable with the mold pockets of anvil 120 to strike the same point or target in mold cups 124p and 124d. It should be understood that tip 146 and tip 246 may not actually strike the same target within molding cups 124p and 124d, for example due to variations in tissue composition. That is, the molding cavity of anvil 120 is configured to guide legs 144 of staple 140 and legs 244p, 244d of staple 240 into a desired alignment. To this end, proximal molding cup 124p includes guide wall 126p and distal molding cup 124d includes guide wall 126d that guides the legs of staples 140, 240, and 240' into the desired configuration. Configured to guide and shape.

Referring again to FIG. 7, staple 240 includes a tissue engaging surface 243 defined on the top surface of crown portion 242 . Surfaces 243 of staples 240 are configured to support and/or apply pressure to tissue captured within staples 240 as staples 240 are formed into a firing configuration. Referring now to FIG. 11, surface 243 of staple 240 is positioned well below deck 233 of cartridge body 232 when staple 240 is in the unfired position. Referring now to FIG. 12, surface 243 emerges at least partially above deck 233 when staple 240 is moved to the firing position. In other words, sled 250 is at least partially overdriven over staples 240 . In such cases, surface 243 of staple 240 may abut and apply pressure to tissue as staple 240 is being deformed. In some cases, only a portion of surface 243 is overdriven above deck 233 when 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, further to the above, drivers 246 of staples 240 remain at least partially below deck 233 even when surfaces 243 of staples 240 are overdriven above deck 233 . In some cases, staples 240 are configured such that drivers 246 do not emerge above deck 233 regardless of the extent to which surface 243 is overdriven above deck 233 . In such a case, the entirety of driver 246 still remains below deck 233 during the staple firing stroke. In at least one example, cam surface 245 of staple 240 does not emerge above deck 233 when staple 240 is overdriven. In various examples, top surface 253 of longitudinal ramp 255 does not extend above deck 233 . This means that the sled 250 does not drive the entire staple 240 up the deck 233 during the staple firing stroke.

Further to the above, it should be understood that the protrusion 236 extends above the deck 233 . As shown in FIG. 12, sled 250 is configured to at least partially overdrive surface 243 of staple 240 above protrusion 236 . In such instances, surface 243 is at least partially elevated above protrusion 236 when staple 240 is moved to the fully fired position. In some cases, only a portion of surface 243 is overdriven above protrusion 246 when staple 240 is in the fully fired position. In other cases, the entire surface 243 is overdriven above the projections 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, tissue engaging surface 243 may directly engage or contact tissue. In other cases, an auxiliary material, such as, for example, a piece of buttress material and/or a tissue thickness compensator, may be disposed on deck 233 of staple cartridge 230, and tissue engaging surface 243 may be attached to the auxiliary material. Direct engagement or contact may be used. References disclosing supporting materials are incorporated by reference elsewhere in this application.

Referring again to FIG. 7, tissue engaging surface 243 has a flat portion, a first angled portion on a first side of the flat portion, a second angled portion on a second side of the flat portion, and a second angled portion on a second side of the flat portion. It has Such a configuration allows pressure to be applied to tissue captured within staples 240 from three directions. That is, tissue engaging surface 243 may have 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 selectively and interchangeably used with end effector 100 . As also discussed above, staple cartridges 130 and 230 are removably attachable to jaws 110 . In various alternative embodiments, staple cartridges 130 and 230 each include a complete jaw that is attachable to and removable from frame 190 of end effector 110 . In such a case, the clinician, for example, removes the entire staple cartridge jaw from the end effector 110 and removes another complete staple cartridge jaw, i.e., the type of staples and/or desired by the clinician that has not yet been fired. Or it can be replaced with one with a pattern of staples.

In addition to the above, it should be understood that FIG. 6 is intended to illustrate that end effector 100 can be used with staple cartridge 130 and staple cartridge 230. FIG. 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 in the same end effector 100 at the same time. Thus, for example, various embodiments are contemplated in which the staple cartridge utilizes wire staples as well as staples formed from one or more sheets of material. In at least one embodiment, the staple cartridge includes, for example, staples 140 and staples 240 removably stored therein. For example, other embodiments are contemplated in which the staple cartridge comprises staples 140, staples 240, and staples 240'.

Referring to FIG. 20, further to the above, staple cartridge 430 includes cartridge body 432 including deck 433 and longitudinal slot 135 defined therein. Longitudinal slot 135 defines a longitudinal slot axis 139 extending through its center. Staple cartridge 430 includes, on one side of longitudinal slot 135, a first or inner row of longitudinally extending cavities 434a, a second or intermediate row of longitudinally extending staple cavities 434b, and a third row of staple cavities 434b. and an outer or outer longitudinally extending row of staple cavities 434c. Staple cartridge 430 also has, on the other side of longitudinal slot 135, a first or inner longitudinally extending row of cavities 434a' and a second or intermediate longitudinally extending row of staple cavities 434b'. 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). Staples 240 are removably stored in staple cavities 434a, 434a', 434b, and 434b'. Staples 140 are removably stored in staple cavities 434c and 434c'.

Referring to FIG. 21, staple cartridge 430 further includes sled 450 configured to eject staples 140 and 240 from cartridge body 432 . Sled 450 directly engages staples 240 stored within staple cavities 434a′ with longitudinal ramps 455a configured to directly engage staples 240 stored within staple cavities 434a. longitudinal ramps 455a' configured to directly engage staples 240 stored within staple cavities 434b and staples stored within staple cavities 434b'; 240 and longitudinal ramps 455b' configured to directly engage. Sled 450 further includes a longitudinal ramp 455c configured to eject staples 140 from staple cavities 434c and a longitudinal ramp 455c' configured to eject staples 140 from staple cavities 434c'. . More specifically, staple cartridge 430 includes a row of staple drivers configured to support and/or engage staples 140 stored within staple cavities 434c and staples 140 stored within staple cavities 434c′. and a row of staple drivers configured to support and/or engage the staples 140 that have been placed in the longitudinal direction of the sled 450 as the sled 450 is advanced distally. Ramps 455 c and 455 c ′ engage staple drivers to lift staples 140 upward within staple cavities 434 c and 434 c ′ and deform staples 140 against anvils disposed on opposite sides of staple cartridge 430 . These staple drivers may be similar in many respects to the staple driver shown in FIG. 3A, for example.

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

The rows of longitudinally extending staple cavities defined within staple cartridge 430 are not evenly spaced. In many respects, the distances between the longitudinally extending rows are different. As can be seen in FIG. 20, the spacing of rows of longitudinally extending staple cavities 434a, 434b, and 434c on one side of longitudinal slot 135 is equal to that of longitudinally extending staple cavities on the other side of longitudinal slot 135. The column spacing of 434a', 434b', and 434c' is different.

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

As can be seen in Figure 21, none of the distances 457a, 457a', 457b, and 457b' are equal. They are all different. As a result, the rails of sled 450 are asymmetrically spaced apart.

Referring to FIG. 21, sled 450 includes central portion 451 configured to move within longitudinal slot 135 of cartridge body 432 . Central portion 451 is sized and configured to be tightly received within slot 135 so that little, if any, lateral movement is permitted between sled 450 and cartridge body 432, The longitudinal ramp of sled 450 remains properly aligned with staple drivers configured to drive staples 240 and 140 .

Referring again to FIG. 20, the outer rows of staples deployed by staple cartridge 430 are wire staples, and the inner and middle rows of staples deployed by staple cartridge 430 are formed from flat stock and/or are hammered. It has been removed. However, other configurations are also conceivable. In at least one example, for example, the middle and outer rows of staples deployed by the staple cartridge are wire staples and the inner rows of staples deployed by the staple cartridge are punched staples. In other examples, for example, the inner and middle rows of staples deployed by the staple cartridge are wire staples and the outer rows of staples deployed by the staple cartridge are die-cut staples. If the staple cartridge deploys more than one row of wire staples on either side of the longitudinal slot, more than one row of staple drivers may be utilized to deploy staples from the staple cartridge. In various examples, the staple cartridge may, for example, utilize a dual driver that simultaneously deploys wire staples from two longitudinal rows when the longitudinal rows containing the wire staples are adjacent one another. It is configured to Other driver configurations configured to deploy more than two staples may be utilized, such as, for example, three staples and/or four staples.

As a result of the foregoing, staple cartridge 430 produces an asymmetrical pattern of staples in tissue. In particular, staple cartridge 430 produces a first pattern of staples in tissue on a first side of the cut line and a second or different pattern of staples in tissue on a second side of the cut line.

15-19, staple cartridge 330 includes cartridge body 332 including deck 333 and longitudinal slot 135 defined therein. Longitudinal slot 135 defines a longitudinal slot axis 139 extending through its center. Staple cartridge 330 includes, on one side of longitudinal slot 135, a first or inner row of longitudinally extending cavities 334a, a second or intermediate row of longitudinally extending staple cavities 334b, and a third row of staple cavities 334b. and an outer or outer longitudinally extending row of staple cavities 334c. Staple cartridge 330 also has, on the other side of longitudinal slot 135, a first or inner longitudinally extending row of cavities 334a' and a second or intermediate longitudinally extending row of staple cavities 334b'. and a third or outer longitudinally extending row of staple cavities 334c'. Staple cavities 334a, 334a', 334b, 334b', 334c, and 334c' are similar in many respects to left staple cavity 234a (Figs. 4 and 6). Staples 240 are removably stored in staple cavities 334a, 334a', 334b, 334b', 334c, and 334c'.

16 and 17, staple cartridge 330 further includes sled 350 configured to eject staples 240 from cartridge body 332 . Sled 350 directly engages staples 240 stored within staple cavities 334a′ with longitudinal ramps 355a configured to directly engage staples 240 stored within staple cavities 334a. longitudinal ramps 355a' configured to directly engage staples 240 stored within staple cavities 334b and staples stored within staple cavities 334b'; and a longitudinal ramp 355b' configured to directly engage 240. Sled 350 directly engages staples 240 stored within staple cavities 334c′ with longitudinal ramps 355c configured to directly engage staples 240 stored within staple cavities 334c. and a longitudinal ramp 355c' configured to.

In addition to the above, staple cavities 334a are positioned along longitudinal axis 337a, staple cavities 334b are positioned along longitudinal axis 337b, and staple cavities 334c are positioned along longitudinal axis 337c. Similarly, staple cavity 334a' is positioned along longitudinal axis 337a', second staple cavity 334b' is positioned along longitudinal axis 337b', and staple cavity 334c' is positioned along longitudinal axis 337c'. are placed. The distance between longitudinal axis 337 a and longitudinal slot axis 139 is less than the distance between longitudinal axis 337 a ′ and longitudinal slot axis 139 . As a result, longitudinal axis 337a' is laterally staggered or offset relative to longitudinal axis 337a. Similarly, the distance between the longitudinally extending row of staple cavities 334a and the longitudinal slot 135 is less than the distance between the longitudinally extending row of staple cavities 334a' and the longitudinal slot 135.

Additionally, the distance between longitudinal axis 337 b and longitudinal slot axis 139 is less than the distance between longitudinal axis 337 b ′ and longitudinal slot axis 139 . As a result, longitudinal axis 337b' is laterally staggered or offset relative to longitudinal axis 337b. Similarly, the distance between the longitudinally extending row of staple cavities 334b and the longitudinal slot 135 is less than the distance between the longitudinally extending row of staple cavities 334b' and the longitudinal slot 135. Further, the distance between longitudinal axis 337c and longitudinal slot axis 139 is less than the distance between longitudinal axis 337c' and longitudinal slot axis 139. As a result, longitudinal axis 337c' is laterally staggered or offset relative to longitudinal axis 337c. Similarly, the distance between the longitudinally extending rows of staple cavities 334c and the longitudinal slots 135 is less than the distance between the longitudinally extending rows of staple cavities 334c' and the longitudinal slots 135.

In addition to the above, longitudinal axes 337a, 337a', 337b, 337b', 337c, and 337c' include drive axes. These drive axes are aligned with the drive portions of staples 240 . The longitudinal ramps of sled 350 are aligned with these drive axes. For example, longitudinal ramp 355a of sled 350 is aligned with longitudinal axis 337a. Similarly, longitudinal ramp 355b is aligned with longitudinal axis 337b and longitudinal ramp 355c is aligned with longitudinal axis 337c.
