The term "proximal" refers to the part closest to the clinician and the term "distal" refers to the part located away from the clinician. For convenience and clarity, it will be further understood that spatial terms such as "vertical", "horizontal", "top", and "bottom" may be used for drawings herein. Let's go. However, surgical instruments are used in many orientations and positions, and these terms are not intended to be limited and / or absolute.

Various exemplary devices and methods are provided for performing laparoscopic and minimally invasive surgical procedures. However, it is readily apparent to the reader that the various methods and devices disclosed herein can be used in many surgical procedures and applications, including those associated with, for example, open surgical procedures. Will be done. By reading "Forms for Carrying Out the Invention" herein, the reader can read that the various instruments disclosed herein are incised or punctured into tissue, eg, through a natural opening. You will further recognize that it can be inserted into the body in any way, such as through a hole. The working part or end effector part of these instruments can also be inserted directly into the patient's body, or like a trocar with a passage of action that allows the end effector and long shaft of the surgical instrument to be advanced. It can also be inserted through an access device.

The staples or fasteners disclosed herein are configured for use with surgical staple fasteners. As discussed in more detail below, the staples are detachably housed within the staple cavities of the staple cartridge. The staple cartridge comprises a thread configured to receive a firing activation from a surgical staple fastening device that exerts a force on the staple to eject the staple from the staple cavity. When the staples are ejected or driven out of the staple cavity by threads, the staples undergo a transformation process in which the staples form a fired configuration from an unfired configuration. Staples form a fired configuration when the staples come into contact with the corresponding molded pockets on the anvil of the surgical staple fastener.

The various staples disclosed herein include, for example, flat shaped staples that can be cut and / or punched from a sheet of material. The sheet of material may be made of metal and may include, for example, stainless steel and / or titanium. In at least one example, contours are traced, etched, and / or cut into sheets of material that are machined and / or laser cut to shape staples into the manufactured shape.

The staples include a pair of staple legs and a staple base or crown from which the staple legs extend. Each staple leg includes a staple tip or puncture portion configured to puncture the tissue and contact the corresponding molded pocket of the anvil of the surgical staple fastening device. The staple legs are configured to change shape to achieve a molded configuration and secure the tissue. The staple base defines a first plane and the staple legs define a second plane that is offset laterally from the first plane but is at least substantially parallel to the first plane. .. An embodiment in which the first and second planes are not parallel is recalled.

The flat-shaped staple 100 shown in FIGS. 1 to 4 includes a proximal staple leg 110, a distal staple leg 120, and a staple base 130. Staples 100 further include vertical transitions or blends 118, 128 and lateral transitions or blends 116, 126. The vertical transition portions 118, 128 bend the legs 110, 120 vertically or upward from the staple base 130, or extend from the staple base 130. The lateral transition portions 116, 126 extend laterally outwardly or at least substantially perpendicular to the staple base 130 the staple legs 110, 120. The staple legs 110, 120 define a first plane and the staple base 130 defines a second plane. The vertical transition portions 118, 128 and the lateral transition portions 116, 126 together allow the staple legs 110, 120 to be laterally offset and parallel to the staple base 130. In other words, the first plane is offset from the second plane and is at least substantially parallel to the second plane. In FIGS. 1 to 4, the first plane is offset in the negative Y-axis direction. Other staples may be used with the plurality of staples 100, and the other staples include a first plane offset in the positive Y-axis direction. By using both types of staples, the staple rows are nested or interwoven, and the staple legs of adjacent rows are at least substantially aligned and / or share a common longitudinal axis. .. In various examples, the staple rows can be nested to provide a denser staple row.

The proximal staple leg 110 and the distal staple leg 120 include staple tips 112, 122 and corners 114, 124, respectively. The tips 112, 122 are configured to puncture the tissue and contact the anvil molded pocket of the surgical staple closure device. The tips 112, 122 come into contact with the anvil when the staple 100 receives a driving force to eject the staple 100 from the corresponding staple cavity in the staple cartridge. The tips 112, 122 and / or legs 110, 120 of the staple 100 then begin to form the fired configuration from the unfired configuration. The proximal staple leg 120 further includes a leading engaging foot 117 including a chamfered surface or edge 119. When the thread comes into contact with the staple 100 during the distal translation of the thread, the thread features engage the leading engaging foot 117 to help prevent, for example, longitudinal rolling or rotation of the staple. Can be done. The engaging foot portion 117 may include a pressing point that is pressed to fill the staple 100 into the staple cartridge.

Because the staple 100 is a flat shaped staple, the staple legs 110, 120, tips 112, 122, and / or other parts of the staple 100, after being punched from a flat, or at least substantially flat, raw material. Can be further developed or processed. Further deployment of the staple 100 may provide specific properties that generate and / or modify the preferred flex plane, toughness, and / or elasticity. Staples formed of conventional wires include the desired properties that favor surgical fixation and can mount staples 100. For example, the method for constructing the corners 114, 124 and / or the tips 112, 122 may include any suitable process, including, for example, cold working. The specific process involves imprinting the corners 114, 124 by processing into a rounded, angled, oblique and / or radial profile. Staple tips 112, 122 can also be machined using a similar method to provide suitable tips configured to puncture tissue and form into the corresponding forming pocket of the anvil.

The staple base 130 includes an inclined drive surface 132, a final drive surface 131, and a distal wall 133. In various embodiments, the staple 100 is supported in the staple cartridge by a pan, and the final drive surface 131 is configured to rest on the pan. In various other embodiments where the staple cartridge does not have a pan, the final drive surface is not placed on the pan, rather the final drive surface includes an initial position on the bottom surface of the staple cartridge that does not have a pan. This allows the bottom of the thread and the bottom of the staple cartridge without pan to be at least substantially the same height as the thread translates through the cartridge. Drive surface 132 of each staple base 130 is configured to receive the driving force F _s from the thread of the surgical stapling instrument. As the thread translates distally through the staple cartridge, the thread contacts the drive surface 132 to lift the staple 100 out of the cartridge and further contacts the final drive surface 131 to form the staple 100 into its launched configuration. To do.

The distal wall 133 functions as the most distal wall of the staple base 130 and is located proximal to the distal staple leg 120, thereby any of the staple base 130 under the distal staple leg 120. Lacking a part. By most of the mass is in the base 130 of the staple 100, the ability of the staple 100 to resist rotational movement caused by the moment M _S applied by the thread increases. By increasing the moment of inertia of the staple base 130, the ability to resist rotational movement increases. As a result, greater torque or greater moment is required to cause longitudinal staple rotation.

The staple base 130 further includes an upper surface or pressurized surface 136 including a proximal surface 139, an intermediate surface 138, and a distal surface 137. The proximal surface 139 is angled or tilted upwards towards the proximal leg 110. The distal surface 137 is angled or tilted upwards towards the distal leg 120. The intermediate surface 138 is at least substantially parallel to the final drive surface 131. This valley configuration limits the stress concentration of the tissue trapped near the transitions 118, 128, 116, 126, with the legs 110, 120 extending from the staple base 130. In various embodiments, these surfaces 137, 138, 139 may be curved to form a concave surface. In conventional staples, when molded, the connection where the leg intersects the staple base creates a highly localized position for tissue stress. This is especially true if such conventional staples are buckled, crushed or flat rather than formed into a true "B" configuration.

In various embodiments, the dynamics of the staple 100 are predictable as they are ejected from the staple cartridge. The staple 100 is ejected from the corresponding staple cavity, the driving force F _S from the thread produces a moment M _s. One precautionary measure to prevent the staple from rotating is to increase the moment of inertia of the staple 100, which is configured to prevent the staple from rolling or rotating in the longitudinal direction as shown in FIG. including. When the staple 100 rolls distally and longitudinally, in other words, when it rotates counterclockwise around the Y-axis, the outer longitudinal staple leg surfaces 115, 125 of the staple 100 become the guide surface of the staple cartridge or It will come into contact with the side wall. This contact _produces a corresponding stress _{F C1} and _{F C2.} More specifically, the staple 100 is driven out of the staple cavity and rotates about the Y axis, and the wall 115 of the proximal staple leg 110 contacts the proximal side wall of the staple cartridge and is below the center of mass. It produces a reaction force _{F C2} acting on the staple legs 110. The wall 125 of the distal staple leg 120 contacts the distal side wall of the staple cartridge and creates a reaction force _FC1 acting on the staple leg 120 above the center of mass. Reaction force of both the F _C1 and _{F C2} contribute to reaction force moment _{M RC} to or balanced to counteract the added moment _{M S} acting on staple 100. The reaction forces discussed herein can be distributed loads acting on the respective surface areas of the staple legs 110, 120.

The moment of inertia of the staple 100 is also configured to prevent lateral rolling or rotation of the staple 100, as shown in FIG. The staple base 130 includes a notch 134 defined in the upper surface 136 of the side portion of the staple base 130 closest to the legs 110, 120. The notch 134 contributes to the predictability of the dynamics of the staple 100 before and during molding when ejected from the staple cartridge. For example, primarily with reference to FIG. 4, the notch 134 is configured to induce rotation of the staple 100 towards a particular cavity sidewall. Or staples 100 from rolling laterally, or in other words, when rotated in the direction of the added moment M _S, longitudinal staple legs walls 111 and 121 of the outer staple 100, and the guide surface or side wall of the staple cartridge They will come into contact and produce the corresponding reaction forces _FC1 and _FC2 . For example, the staple 100 is driven out of the staple cavity and rotates in the direction of the added moment _{M S,} walls 111, 121 of the staple legs 110, 120, in contact with the corresponding side walls of the staple cartridge, the center of mass produce _{F C1} acting on the staple legs 110, 120 of the upper. The outer lateral wall 135 of the staple base 130 contacts another corresponding side wall of the staple cartridge to create a reaction force _FC2 acting on the staple base 130 below the center of mass. Reaction force _{F C1} and _{F C2} produces a reaction force moment _{M RC} of or to balance counteract the appended moment _{M S} act of staples 100 from the thread. The reaction forces discussed herein can be distributed loads acting on the respective surface areas of the staple legs 110, 120, and the staple base 130. In various embodiments, the staple 100 is added to control which wall of the staple cavity is contacted for staple induction as the staple 100 is ejected from the corresponding staple cavity of the staple 100. It is promoted to roll laterally in the direction of the moment M _S.

5 and 6 show a staple 200 made of wire, including a staple leg 210 and a staple base 230. The staple leg 210 is offset from the staple base 230 and bends at a substantially 90 degree angle from the staple base 230. The staple leg 210 is in a first plane that is at least substantially perpendicular to the second plane defined by the staple base 230 and the bend 220 of the staple leg 210.

7-10 show a staple 300 including a proximal staple leg 310, a distal staple leg 320, and a staple base or crown 330 having a driving surface 332. The staple legs 310, 320 extend from the staple base 330, and each staple leg 310, 320 includes a laterally outwardly bent portion and an upwardly bent portion. The laterally outwardly bent portion of the staple leg bends the staple leg laterally outward with respect to the staple base. The upward bend of the staple leg causes the staple leg to bend upward with respect to the staple base. The staple 300 includes a first zone 331 including a first hardness, second zones 311 and 321 including a second hardness, and a third zone 312 and 322 including a third hardness. Embodiments are recalled that include more or less zones than the staples 300 shown. Changing certain properties of different parts of the staple 300, such as hardness, provides greater control and predictability when molding staples against corresponding molding pockets, eg, molding pocket 341 of anvil 340. To. The first hardness of the first zone 331 may be higher than the second hardness of the second zones 311 and 321. In many examples, it is flexible enough to support the staple legs 310, 320 and, for example, have the staple base 330 having a hardness higher than the staple legs 310, 320, yet be permanently reshaped without breaking. It is desirable to have staple legs 310, 320, in other words, to have staple legs 310, 320 with a high degree of plasticity. Higher hardness will increase the ability of the staple base 330 to resist deformation upon application of external and / or internal forces, such as forces from the staple legs when pressurized against the anvil. ..

The metalworking of different parts of the staples disclosed herein may include several advantages. One of these advantages is that it prevents the staple legs from shattering or buckling during molding and instead the staple legs deform to the desired configuration as a result of contact with the corresponding molding pockets. It may include that it can be promoted.

The staples 300 can be molded into any desired shape. In the configuration of unformed staple legs 310 and 320 defines a first plane _{P 1,} the staple base 330 defines a second plane _{P 2.} Staple legs 310 and 320 an example of the shape of the staple 300 which is formed in the lateral direction toward the second plane _{P 2} is shown in FIGS. 9 and 10. The change in hardness of a particular zone and / or portion of the staple 300 can be responsible for providing directional facilitation upon contact with the molding pocket 341. Staple legs 310 and 320, the embodiment is shaped in a direction away laterally from the second plane P ₂ will occur.

The staple base 430 includes a rectangular cross-section profile 431 and the staple legs include a circular cross-section profile 411. A circular staple leg 410 extending from a staple base 430 having a rectangular cross-sectional profile 431 can provide a staple base and staple legs that do not include a preferred bending plane. The staple 400 includes a bend 420 in which the staple leg 410 extends from the staple base 430. The bend 420 includes a substantially square cross-sectional profile 421. The square profile 421 and rectangular profile 431 of the bend 420 and staple base 430, respectively, provide a solid connection and skeleton to the circular staple legs 410. The circular staple leg 410 eliminates the preferred bending plane that a staple leg having a square, rectangular, or topped, arbitrary or non-uniformly shaped cross section may have.

FIG. 12 shows a staple 500 according to at least one embodiment, including a proximal staple leg 510, a distal staple leg 520, and a staple base 530 extending the staple legs 510 and 520. The proximal staple leg 510 is laterally bent outward from the staple base 530 in the first direction. The distal staple leg 520 bends laterally outward in a second direction from the staple base. The first direction is opposite to the second direction. The staple base 530 defines a first plane and the staple legs 510 and 520 define a second plane that intersects the first plane. One advantage of having staple legs 510 and 520 bent in opposite directions is that they can help prevent lateral rotation by reacting with the applied thread moments on each side of the staple base 530. is there. This results in an S-shaped configuration and requires an auxiliary molded pocket.

A staple 600 including a proximal leg 610, a distal leg 620, and a staple base 630 having a driving surface 632 is shown in FIG. The distal leg 620 is longer than the proximal leg 610, thereby providing offset contact timing for the tips 611, 621 of the staple legs 610, 620 with respect to the anvil molding pocket. In various embodiments, the distal leg may include a tip containing a pre-bent initial configuration to aid the molding process upon initial contact with the anvil. The preformed tip 621 will require less pressure than the staple tip 611 to initiate deformation with respect to the anvil. Contacting the longer staple leg, which in this case is the distal staple leg 620, with the anvil in front of the shorter or proximal staple leg 610 is that the staple tip 621 of the longer leg 620 It may be necessary to have some preformed tips before the tips 611 are deformed.

FIG. 14 shows the arrangement 700 of the molded staples 711 and 721. The staples 711 are placed in the first row 710 and the staples 721 are placed in the second row 720 adjacent to the first row 710. The staples 711, 712 may be similar to those of the staple 600 shown in FIG. 13 discussed above. The staples 711 include laterally opposed legs 713,715. The staples 721 include laterally opposed legs 723,725. The laterally opposed legs 713, 715 include tips configured to contact the anvil molding pocket at contact points 713c, 715c, respectively. The laterally opposed legs 723, 725 also include tips configured to contact the anvil molding pocket at contact points 723c, 725c, respectively. The legs 713 and 715 facing each other in the lateral direction are formed inward toward the staple base on which the legs extend from the legs, respectively. The laterally opposed legs 723, 725 are also molded inward towards the staple base from which the legs extend.

The staple rows 710, 720 are woven so that the contact points 723c, 713c are substantially aligned. Such an arrangement allows for a denser array of staple rows in the staple cartridge and / or a denser molded pocket configuration on the anvil. Also, weaving scaffold planes can provide higher quality scaffolds and scaffold coverage within tissues of larger area. The woven scaffold plane can ensure that what is trapped between the staple rows and the molding pocket is properly secured. This can help in stapling smaller and / or less easily visible vessels that can lead to stapling column separations that result in less than sufficient fixation with conventional staple arrangements.

15-17 show staples 800 including staple legs 810, 820 and staple base 830 having a drive surface 832. The staple legs 810, 820 include a tip 842 configured to contact the anvil molding pocket, for example, the molding pocket 861 of the anvil 860. The staple tip 842 includes a puncture tip or portion 842T, a curl surface 842S, and a concave notch 842C. The puncture tip 842T is configured to puncture the tissue T when ejected from the staple cartridge and to deform within the molding pocket 861 when in contact with the molding pocket 861 of the anvil 860. Deformation of the staple tip 842 into a particular shape is facilitated by utilizing the predictable deformability of the concave notch 842C. The curled surface 842S of the staple tip 842 is configured to curl or deform from the puncture position 812A to the intermediate molding position 812B and the non-puncture position 812C. When the staple tip 842 is completely deformed, the puncture tip 842T is hidden or separated from the tissue T by the curl surface 842S. This prevents further puncture of tissue T after the tip 842 has punctured the tissue during drainage. This arrangement also prevents further damage and / or unnecessary irritation that the exposed puncture tip may inflict after the initial puncture. Preventing further puncture of the tissue T after the leg has been formed also reduces the likelihood that the staple 800 will be drawn into the tissue T. The curl surface 842S acts as a shield configured to hide the puncture tip 842T from the tissue T.

FIG. 18 shows a plurality of examples of different types of staple tips 871, 872, 873, 874, and 875 that can be used with any suitable surgical staple, such as the staples disclosed herein.

Next, with reference to FIGS. 27-27B, the staple leg 1300 is shown. The staple leg 1300 includes a substantially circular staple tip and has a substantially square staple leg and a staple leg body portion 1301. The staple leg 1300 includes hardened corners formed using the imprint process, for example, the corners 1303A, 1303B, 1303C, and 1303D are rounded to create a preferred bending plane. In other words, the staple leg 1300 includes a cross-sectional profile configured to facilitate bending of the staple leg 1300 in a particular direction due to hardening of the corners upon contact with the anvil. The corners 1303A, 1303B, 1303C, and 1303D may have different hardnesses for each corner, or may include two corners having a first hardness and two other corners having a second hardness. The corners 1303A, 1303B, 1303C, and 1303D can be imprinted to provide different radial profiles on the same staple leg. For example, the corners 1303A includes a radial profile having a radius _{R B} is greater than the radius _{R A} of the radial profile of the corner portion 1303B shown in Figure 27B.

Some of the staples disclosed herein can be cured at various points in the manufacturing process by any suitable means. For example, the curing process can include, for example, bronzing, chemical vapor deposition, physical vapor deposition, laser surface treatment, thermal oxidation, ion nitriding, and / or solid diffusion. Other parts of the staples can be prevented from being cured by these processes. Other parts of the staple, such as the staple tip, can be locally annealed. By specifically increasing the hardness of the region, the force required to disassemble the staple after the staple has taken the launched configuration can be increased.

28-28C show staples 1400 and threads 1460 according to at least one embodiment. The staple 1400 includes staple legs 1410, 1420, a staple base 1430 extending the staple legs 1410, 1420, a drive surface 1432, and a bottom surface 1431. The staple legs 1410, 1420 extend from the staple base 1430 in a plane parallel to and offset from the plane defined by the staple base 1430. Staples 1400 are made by progressive punching utilizing a base strip 1450 and a connector portion 1451. Although only a single staple 1400 is shown, multiple staples 1400 are attached to the base strip 1450. The connector portion 1451 connects the staples 1400, specifically the staple base 1430, to the base strip 1450. The connector portion 1451 includes a cut or notch 1453 configured to allow the staple 1400 to be removed from the strip 1450. In at least one example, thread 1460 includes a release portion or striking portion 1461. The release portion 1461 of the thread 1460 engages with the cut 1453 or connector portion 1451 to separate, break and / or shear the staple 1400 from the base strip 1450, and the staple is ejected from the staple cavity of the staple by the thread 1460. It is configured to allow that.

Embodiments are recalled in which the base strip 1450 includes an alignment feature, such as a hole that engages the corresponding alignment feature onto the staple cartridge. Such alignment features may include, for example, a protrusion that is aligned with the alignment features of the base strip 1450. In various examples, a person who fills a cartridge with staples can align the staples into the staple cavities and / or align the alignment features before pushing the staples into the staple cavities. A particular embodiment is recalled in which the staple cartridge comprises an engagement feature configured to engage the cut 1453 when the staple cartridge is filled with a strip assembly. The engagement feature allows the staple 1400 to separate from the strip 1450 when the staple 1400 is filled into the staple cartridge, not when the staple 1400 is fired. Manufacture of staples by progressive punching may allow staples to have different crown dimensions, shapes and / or configurations, and staple leg dimensions, shapes and / or configurations. Another advantage of using progressive punching techniques may include the ability to vary the spacing of the staple rows in which the staples are aligned.

29 and 30 show another embodiment of strip 1500 of staples 1501 made by progressive punching. Strip 1500 of staples 1501 includes base strips 1550, connector portions 1551, and staples 1501. Each staple 1501 first includes a staple base 1530 including a bottom surface 1531 and secondly a staple leg 1510 extending from the staple base 1530. The connector portion 1551 attaches the bottom surface 1531 of the staple base 1530 to the base strip 1550. The staple legs bend upward from the staple base 1530 so that the legs 1510 are offset from the plane defined by the staple base 1530 and placed in at least a substantially parallel plane. In the embodiments shown, the staple legs 1510 bend in a direction opposite to that of the connector portion 1551. By bending the leg portion 1510 and the connector portion 1551 in this manner, a higher density staple row arrangement is allowed. The connector portion 1551 ensures that the staple 1501 is released from the base strip 1550 when the staple 1501 is filled into the staple cartridge and / or when the staple 1501 is fired from the staple cartridge as discussed in the previous embodiment.

Each staple 1601 includes a prefilled configuration, a filled configuration, and a fired configuration in which the staple 1601 is ejected from the staple cartridge 1650 and molded into the corresponding molded pocket of the anvil. The staple leg portion 1610 is bent outward with respect to the staple base portion 1630 in the pre-filling configuration. The staple leg 1610 urges the side wall of the corresponding staple cavity 1651 in the prefilled configuration to define a first distance X between the staple leg 1610 tips 1611. In the pre-filling configuration, the distance between the staple tips 1611 of the staple legs 1610 is greater than X. This urging force helps to support the staple 1601 within the staple cartridge 1650.

The staple cartridge 2000 is shown in FIGS. 32-34. The staple cartridge assembly 2000 includes a cartridge body 2010. The cartridge body 2010 can be positioned at the jaw of the surgical stapler and is removable from the jaw of the surgical stapler. As a result, the staple cartridge 2000 is replaceable. However, other embodiments are recalled in which the staple cartridge 2000 is not replaceable. The cartridge body 2010 includes a proximal end 2011, a distal end 2012, and a deck 2014 extending between the proximal end 2011 and the distal end 2012. The deck 2014 is configured to support the patient's tissue when the tissue is pressed against the deck 2014.

The cartridge body 2010 further includes a plurality of staple cavities 2020 as defined in the present invention. Staple cavities 2020 are arranged in six longitudinal rows extending between the proximal end 2011 and the distal end 2012. However, any suitable arrangement of staple cavities 2020 can be utilized. For example, staples such as staples 2130 (FIG. 40) are detachably housed within each staple cavity 2020. As discussed in more detail below, the staples are ejected from the staple cavity 2020 by the launching member as the firing member moves from the proximal end 2011 to the distal end 2012 of the cartridge body 2010.

In addition to the above, the staples are moved from the unlaunched position to the launched position by the launching member. The launching member lifts the staples toward an anvil, such as the anvil 2190 (FIG. 37), to deform the staples between the unlaunched undeformed configuration and the launched deformed configuration. The cartridge body 2010 further includes a longitudinal slot 2013 defined internally. The slot 2013 is configured to internally receive a staple launching member and / or a tissue cutting member as the staple is ejected from the staple cavity 2020.

In various embodiments, in addition to the above, the staples do not project onto the deck 2014 until the staples are moved towards the anvil by the launching member. Such embodiments often utilize small staples. In another embodiment, the legs of the staples project onto the deck 2014 when the staples are in their unlaunched position. In at least one such embodiment, the cartridge body 2010 further includes a protrusion 2050 extending from the deck 2014. The protrusion 2050 extends the staple cavity 2020 over the deck 2014 and guides the staple towards the anvil as the staple is ejected from the staple cartridge 2000. In such an embodiment, the staples may not project onto the protrusion 2050 until the staples are moved towards the anvil by the launching member.

Primarily with reference to FIG. 34, the protrusion 2050 does not extend around the entire staple cavity 2020. The first protrusion 2050 is positioned adjacent to the first end of each cavity 2020 and the second protrusion 2050 is positioned adjacent to the second end of each cavity 2020. Each first protrusion 2050 extends around the first staple leg guide 2022 of the staple cavity 2020, and each second protrusion 2050 is of the second staple leg guide 2023 of the staple cavity 2020. It extends around. Each first protrusion 2050 provides a proximal bracket capable of controlling and guiding the proximal leg of the staple, and each second protrusion 2050 controls and guides the distal leg of the staple. Provide a distal bracket that can. The first protrusion 2050 of each staple cavity 2020 is not symmetrical with respect to the first end of the staple cavity 2020 and does not extend around the entire first end of the cavity 2020. Similarly, the second protrusion 2050 of each staple cavity 2020 is not symmetrical with respect to the second end of the staple cavity 2020 and does not extend around the entire second end of the cavity 2020. The first protrusion 2050 and the second protrusion 2050 include a mirror image of each other and are symmetrically arranged with respect to the center of each staple cavity 2020. However, any suitable arrangement of protrusions can be utilized.

As shown in FIGS. 32 to 34, the cartridge body 2010 includes a step 2014'and a step 2014' that extend upward from the deck 2014. More specifically, the step 2014' extends upward from the deck 2014. However, the step 2014 "extends upward from the step 2014'. As a result, step 2014'can apply a compressive pressure greater than step 2014' to the tissue, similarly step 2014'can apply a compressive pressure greater than deck 2014 to the tissue. Steps 2014'and 2014' Although including a twisted longitudinal flat portion, steps 2014'and 2014' may include any suitable configuration. In addition to the above, the overhang 2050 extending from step 2014' may include step 2014'. The protrusion 2050 extending from the overhanging portion 2050 extending from, and similarly extending from the step 2014', extends over the protruding portion 2050 extending from the deck 2014. In other words, the deck 2014, the step 2014', and the protrusion 2050 extending from the step 2014'are twisted.

The staple cartridge 2100 is shown in FIGS. 35-38. The staple cartridge assembly 2100 comprises a cartridge body 2110 and is in many respects similar to the staple cartridge assembly 2000 and / or the other staple cartridges disclosed herein. The cartridge body 2110 includes a deck 2114, a plurality of staple cavities 2120a, and a plurality of staple cavities 2120b. The staple cavity 2120a is similar to the staple cavity 2120b in many respects. For example, the staple cavities 2120a and 2120b both have a central slot 2121 having a proximal end and a distal end, and a proximal staple leg guide 2122 extending laterally from the proximal end of the central slot 2121. Includes a distal staple leg guide 2123 extending laterally from the distal end of central slot 2121. Therefore, the staple cavity 2120a and the staple cavity 2120b are oriented in different directions. More specifically, the staple leg guides 2122 and 2123 of the staple cavity 2120a extend toward the staple cavity 2120b, and similarly, the staple leg guides 2122 and 2123 of the staple cavity 2120b point toward the staple cavity 2120a. It is extended. However, any suitable arrangement can be utilized.

The staples 2130a are positioned within each staple cavity 2120a and the staples 2130b are located within each staple cavity 2120b. Staples 2130a and staples 2130b are similar in many respects. For example, each staple 2130a includes a base or crown 2131, a proximal leg 2132 extending from the proximal end of the base 2131, and a distal leg 2133 extending from the distal end of the base 2131. .. Therefore, the staples 2130a and 2130b are fitted in a manner for fitting into the staple cavities 2120a and 2120b, respectively. For example, when the staples 2130a are positioned in the staple cavities 2120a and the staples 2130b are positioned in the staple cavities 2120b, the staples 2130a's legs 2132, 2133 extend towards the staples 2130b and the staples 2130b's legs 2132, 2133 extends towards staples 2130a. However, other arrangements are possible.

In addition to the above, when the staples 2130a and 2130b are housed in the staple cavities 2120a and 2120b, respectively, the proximal leg 2132 of the staples 2130a and 2130b is positioned in the staple leg guide 2122. Similarly, if the staples 2130a and 2130b are housed in the staple cavities 2120a and 2120b, respectively, the distal leg 2133 of the staples 2130a and 2130b is positioned within the staple leg guide 2123. Further, when the staples 2130a and 2130b are housed in the staple cavities 2120a and 2120b, respectively, the base 2131 of the staples 2130a and 2130b is positioned in the central slot 2121 of the staple cavities 2120. Primarily with reference to FIG. 35, the tips of the staple legs 2132, 2133 extend over the deck 2114 of the cartridge body 2110 when the staples 2130a and 2130b are in their unlaunched positions. Thus, the tip of the staple leg 2132 is at least partially surrounded by the proximal protrusion 2152 extending from the deck 2114, and the tip of the staple leg 2133 is at least partially surrounded by the distal protrusion 2153 extending from the deck 2114. Partially surrounded. The proximal overhang 2152 extends around the proximal staple leg guide 2122, but the proximal overhang 2152 does not extend around the proximal end of the central slot 2121. Similarly, the distal protrusion 2153 extends around the distal staple leg guide 2123, but does not extend around the distal end of central slot 2121.

Next, moving to FIG. 38, each proximal overhang 2152 has a first portion 2154 extending around the proximal side of the proximal guide slot 2122 and around the lateral portion of the proximal guide slot 2122. Includes a second portion 2155 extending in. The proximal protrusion 2152 does not extend around the distal side of the proximal guide slot 2122, but in an alternative embodiment, the proximal protrusion 2152 is around the distal side of the proximal guide slot. It is recalled that it can be postponed. Similarly, each garden position protrusion 2153 has a first portion extending around the distal side of the distal guide slot 2123 and a second portion extending around the lateral side of the distal guide slot 2123. Including the part of. The distal protrusion 2153 does not extend around the distal guide slot 2123, but in an alternative embodiment, the distal protrusion 2153 may extend around the proximal side of the distal guide slot. Is recalled. In either case, the arrangement shown in FIG. 38 protects the staple legs 2132, 2133 when the staples 2130a and 2130b are in their unlaunched positions, and further, the staples 2130a and 2130b when the staples are fired. To induce. Such an arrangement also adequately controls the flow of tissue to the deck 2114 of the cartridge body 2110.

With reference to FIG. 38 again, the staple cavities 2120a and staples 2130a are sized and configured to provide a gap between the staples 2130a and the staple cavities 2120a. For example, there is a gap 2156 between the proximal leg 2132 of the staple 2130b and the proximal side wall of the proximal guide slot 2122, as well as the proximal leg 2132 of the staple 2130b and the distal of the proximal guide slot 2122. There is a gap 2158 between the side wall and the side wall. Further, there is a gap 2157 between the lateral portion of the proximal leg 2132 and the proximal guide slot 2122. A similar gap can be seen between the distal leg 2133 and the distal guide slot 2123. Lateral gaps 2126, 2127 may also be provided between the base 2131 of the staples 2130b and the lateral portions of the central slot 2121. Such gaps can be transient and the staples can still contact one or more side walls.

The staple cartridge 2200 is shown in FIG. The staple cartridge 2200 is in many respects similar to the staple cartridges 2000, 2100 and other staple cartridges disclosed herein. The staple cartridge 2200 includes a cartridge body 2210 that includes an internally defined staple cavity 2220. Each of the staple cavities 2220 has staples, such as staples 2130, that are detachably housed inside. Each staple cavity 2220 has a first guide slot 2222 configured to guide the legs 2132 of the staple 2130, and a second guide slot 2223 configured to guide the legs 2133 of the staple 2130. Includes a central slot 2221. The guide slots 2222 and 2223 extend laterally from the central slot 2221, and the central slot 2221 includes an intermediate guide 2225 configured to guide the base 2131 of the staple 2130. The first guide slot 2222 is sized and configured such that the staple legs 2132 are snugly received at the corners of the first guide slot 2222. Similarly, the second guide slot 2223 is sized and configured such that the staple legs 2133 are snugly received at the corners of the second guide slot 2223. The intermediate guide 2225 is sized and configured to limit lateral movement of the staple 2130 within the staple cavity 2220. Further, the intermediate guide 2225 is sized and configured to keep the staple legs 2132 and 2133 in the staple leg guide slots 2222 and 2223, respectively.

As described above, the intermediate guide 2225 is sized and configured to hold the staple legs 2132 and 2133 against the side walls of the guide slots 2222 and 2223, respectively. Such an arrangement produces a lateral reaction force between the lateral side wall of the cavity 2220 and the staple 2130, which is shown as the force vector LT in FIG. Such lateral reaction forces generate frictional thrust between the side walls of the cavity 2220 and the staples 2130 as the staples 2130 are ejected from the cavity 2220. It should be understood that frictional thrust is a function of the surface area to which it is added, so that the intermediate guide 2225 does not extend along the overall length of the central slot 2221. Therefore, the intermediate guide 2225 has a sufficient longitudinal length to control the orientation of the staples 2130 within the cavity 2220. In addition, the intermediate guide 2225 has sufficient vertical length to control the orientation of the staple 2130 during the firing stroke of the staple 2130. In at least one example, the guide 2225 extends along the entire vertical depth of the cavity 2220.

The intermediate guide 2225 is flat and configured to join with a flat surface defined laterally to the base 2131 of the staple 2130, although any suitable arrangement can be utilized. In certain alternative embodiments, the intermediate guide 2225 includes, for example, an elastic urging member configured to apply urging forces to the base 2131 of the staples 2130. In at least one example, the elastic urging member may include, for example, a cantilever spring.

The staple cavity 2220 does not include a lateral guide located opposite the lateral intermediate guide 2225. In fact, there is a gap 2229 between the side wall 2228 and the staple 2130.

In addition to the above, again with reference to FIG. 43, the staple 2130 is not positioned at the end of the central slot 2221. More specifically, the central slot 2221 of the cavity 2220 includes a proximal end 2226 and a distal end 2227, and staples 2130 extend to either the proximal end 2226 or the distal end 2227. do not. Rather, there is a gap between the ends 2226, 2227 and the staple 2130. Such a gap extends between the ends 2226, 2227 and the intermediate guide 2225. As a result, the ends 2226, 2227 of the staple cavity 2220 do not control the longitudinal position of the staple 2130. Instead, staple leg guides 2222, 2223 control the longitudinal position of the staples 2130. In fact, the legs 2132 and 2133 of the staple 2130 can be urged inward by the staple leg guides 2222 and 2223, respectively. Such an arrangement produces a longitudinal reaction force, shown in FIG. 43 as the force vector LG.

As a result of the above, the staple cavity 2220 includes three control points or positions where the staple cavity 2220 controls the orientation of the staple 2130. These control points include separate control positions with gaps defined between them. In other words, the guides 2222, 2223, and 2225 triangulate the control of the staple 2130. An alternative embodiment involving more than three control points is recalled. In either case, the control points provided by the staple leg guides 2222 and 2223 are defined in the first control plane. The intermediate control points provided by the intermediate guide 2225 are defined in the second control plane. An alternative embodiment is recalled in which the first control plane and the second control plane are parallel, but the first control plane and the second control plane are not parallel. Further, the first control plane is aligned with or adjacent to the staple legs 2132 and 2133 of the staple 2130, and the second control plane is aligned with or adjacent to the base 2131 of the staple 2130.

The staple cartridge 2700 is shown in FIG. The staple cartridge 2700 includes a cartridge body 2710 that includes a deck 2714 and a plurality of staple cavities 2220 defined within the deck 2714. Like the cartridge body 2110, the cartridge body 2710 includes protrusions 2752 and 2753 extending over the deck 2714. The protrusion 2752 at least partially surrounds the staple leg guide 2222 of the staple cavity 2220, and the protrusion 2753 at least partially surrounds the staple leg guide 2223 of the staple cavity 2220. Like the overhangs 2152, 2153, the overhangs 2752, 2753 include an outer portion 2754 and a lateral portion 2755, respectively. The outer portion 2754 is positioned longitudinally with respect to the staple leg guides 2222 and 2223, while the lateral portion 2755 is positioned laterally with respect to the staple leg guides 2222 and 2223. Unlike the protrusions 2152, 2153, the protrusions 2752, 2753 include inner portions 2756 positioned longitudinally with respect to the staple leg guides 2222 and 2223, respectively. The inner portion 2756 is connected to the lateral portion 2755 and the lateral portion 2755 is connected to the outer portion 2754. Similar to the above, the protrusions 2752, 2753 extend into the staple cavities 2220 on the deck 2714.

The staple cartridge 2800 is shown in FIG. The staple cartridge 2800 includes a cartridge body 2810 including a deck 2814 and a plurality of staple cavities 2220 defined within the deck 2814. Like the cartridge body 2110, the cartridge body 2810 includes protrusions 2152, 2153 extending over the deck 2114. As outlined above, the protrusion 2152 at least partially surrounds the staple leg guide 2222 of the staple cavity 2220, and the protrusion 2753 at least partially surrounds the staple leg guide 2223 of the staple cavity 2220. Further, the cartridge body 2810 includes an internal protrusion 2856 positioned longitudinally with respect to the staple leg guides 2222 and 2223. The internal protrusion 2856 is not connected to the protrusions 2152, 2153.

With reference to FIG. 35 again, the staple 2130 is driven between the unlaunched and fired positions by a launching member, such as a thread 2140. Threads 2140 include wedges 2145 configured to engage directly with staples 2130 and lift staples 2130 towards anvils such as anvils 2190, for example, as shown in FIG. Thread 2140 includes wedges 2145 for each longitudinal row of staples 2130, but thread 2140 may have any suitable number of wedges 2145. Each wedge 2145 includes an angled drive surface 2141 that slides under the staples 2130 as the threads 2140 travel from the proximal end of the staple cartridge 2100 towards the distal end of the staple cartridge 2100. The base 2131 of each staple 2130 includes a drive surface 2135 at an angle that is in direct contact with the drive surface 2141. In other words, each staple 2130 includes a unique integrated driver with a drive surface 2135. The staples 2130 are made of metal and, as a result, the integrated driver is also made of metal. Therefore, the staples disclosed herein can be made of any suitable material.

In addition to the above, each drive surface 2141 includes an early or distal portion 2142, a second or intermediate portion 2143, and a third or apex portion 2144. The initial portion 2142 extends at a first angle as the thread 2140 is moved distally to provide an initial contact point for the thread 2140 with respect to the staple 2130. As the initial portion 2142 slides under the staples 2130, the staples 2130 are lifted upwards within the staple cavities 2120. As the thread 2140 continues to move distally, the intermediate portion 2143 comes into contact with the staple 2130. The intermediate portion 2143 extends at a second angle different from the first angle. If a rapid initial upward transposition of the staple 2130 is desired, the first angle may be steeper than the second angle and it is desired to provide a stepwise initial upward transposition of the staple 2130. In some cases, the first angle may be gentler than the second angle. In each case, the staples 2130 come into contact with the anvil 2190 while the staples 2130 are being lifted upwards by the intermediate portion 2143, as shown in FIG. An alternative embodiment is recalled in which the staples 2130 come into contact with the anvil 2190 when being lifted. In each case, the proximal leg 2132 of the staple 2130 contacts the proximal molded pocket 2192 defined within the anvil 2190, and the distal leg 2133 is the distal molded pocket defined within the anvil 2190. Contact with 2193. Molded pockets 2192 and 2193 are configured to bend the legs 2132 and 2133 inward to deform the staples 2130 and capture the patient's tissue within the staples 2130. The apex 2144 of the drive surface 2141 slides under the staples 2130 to finish the molding process. The apex 2144 may include a tip of the driving surface 2141, a flat surface, and / or a surface extending at a third angle different from the first and / or second angle.

In various examples, each drive surface 2141 includes a portion that follows or is located proximal to the apex 2144 of the drive surface 2141. Such a rear portion may be lower than, for example, apex 2144. Further, such rear portions may provide, for example, a gradual reduction in molding pressure at staples 2130.

Then, referring to FIG. 39, the staple 2130 further includes a foot portion 2134 extending downward from the proximal leg portion 2132. When the staples 2130 are in their proper orientation within the staple cavities 2120 as shown in FIG. 41, the feet 2134 are not in contact with the threads 2140. In such an example, the placement flat portion 2146 of the thread 2140 passes under the foot portion 2134. When the staples 2130 are not in their proper position within the staple cavities 2120 as shown in FIG. 42, the threads 2140 can contact the staples 2130 and reorient the staples 2130. For comparison purposes, both improperly oriented staples 2130 and properly oriented staples 2130'are shown in FIG. The thread 2140 includes an angled alignment ramp 2148 configured to contact the foot 2134 and rotate the staples 2130 in the proper orientation. After the alignment tilt surface 2148 has properly oriented the staples 2130, the alignment flat portion 2146 can slide under the foot portion 2134. As can be seen from FIG. 39, the inclined surface 2148, the alignment flat portion 2146, and the foot portion 2134 are arranged in an alignment plane aligned with the molding planes of the legs 2132 and 2133 of the staple 2130. To. The alignment plane is adjacent to the lifting plane that includes the molding surface 2141 of the thread 2140 and the base 2131 of the staple 2130.

The staple cartridge assembly 2300 is shown in FIGS. 44-48. The staple cartridge assembly 2300 is in many respects similar to the staple cartridges 2000, 2100, 2200, and other staple cartridges disclosed herein. The staple cartridge 2300 includes a cartridge body 2310 and a thread 2340 configured to eject staples detachably housed in the cartridge body 2310. Like thread 2140, thread 2340 includes a staple molding ramp 2145. The ramp 2145 is slidably positioned in a longitudinal slot 2115 defined within the cartridge body 2110 that is aligned with the raised portion or plane of the staple. In particular, slot 2115 has an open end defined within the bottom 2316 of the cartridge body 2310, as discussed in more detail below.

In addition to the above, the staple cartridge assembly 2300 does not include a cover extending around the bottom 2316 of the cartridge body 2310. Primarily with reference to FIG. 48, the cartridge body 2310 is positioned directly with respect to the jaw portion 2180 of the staple fastening device. In embodiments where the staple cartridge is not easily removable from the jaw of the staple fastener and is not easily replaceable with another staple cartridge, the jaw 2180 is such that the staple falls from the bottom of the staple cavity 2120, and / Or the absence of the bottom cover is not necessarily a problem as it can prevent the threads 2340 from falling from the bottom of the longitudinal slot 2115. However, despite the fact that the staple cartridge assembly 2300 is replaceable and does not include a bottom cover, the staple cartridge assembly 2300 prevents the staples and threads 2340 from falling from the bottom 2316 of the cartridge body 2310, as discussed in more detail below. Includes feature parts. Such features can be adapted to any of the staple cartridges disclosed herein.

Primarily with reference to FIGS. 45-47, the cartridge body 2310 includes a retention feature configured to retain the thread 2340 internally. For example, the cartridge body 2310 includes a proximal holding feature 2317 configured to keep the threads 2340 in longitudinal slots 2115 when the threads 2340 are in their proximal or unlaunched positions. The thread 2340 is in the unlaunched position when the staple cartridge assembly 2300 is inserted or filled into the jaw 2180 so that the proximal holding feature 2317 is threaded when the cartridge assembly 2300 is handled by the clinician. The 2340 is held in the cartridge body 2310. Each holding feature portion 2317 includes an angled surface 2318 and a shoulder portion 2319. Each thread 2340 is capable of aligning and / or contacting a corresponding recess 2348 configured to receive the angled surface 2318 and further a shoulder portion 2319 of the holding feature portion 2317. Includes shoulder 2349 and threads. When the thread 2340 is inserted into the slot 2115, the inclined surface 2145 and / or the side wall of the cartridge 2310 bends and the thread 2340 slides against an angled surface, with reference to FIG. When the shoulder portion 2349 of the thread 2340 is aligned with the shoulder portion 2319 of the cartridge body 2310 as shown in 45, it can be allowed to elastically repel the thread 2340 back to its original position. The retention feature 2317 is also configured to prevent the thread 2340 from sliding proximally out of the longitudinal slot 2115.

As a result of the above, the proximal holding feature 2317 prevents the thread 2340 from falling from the cartridge body 2310 when the clinician is handling the staple cartridge assembly 2300. When the thread 2340 is advancing distally to fire the staples, the thread 2340 is no longer aligned with the proximal holding feature 2317. However, at this point, the staple cartridge assembly 2300 is already in the jaw 2180 and the thread holding feature is no longer needed. Therefore, the cartridge body 2310 may include additional holding features that can keep the threads 2340 within the cartridge body 2310 regardless of the position of the threads 2340. Such retention features may be configured to hold the threads 2340 within the cartridge body 2310, for example, when the threads 2340 are in their distal or fully fired positions.

In addition to the above, the staples of the staple cartridge disclosed herein may include one or more features configured to keep the staples within the staple cavities of the staple cartridge. The staple 2330 then includes a base 2331 and one or more staple legs 2332 extending from the base 2331, with reference to FIGS. 49 and 50. The staples 2330 are detachably housed in, for example, the staple cavities 2320 in the cartridge body 2310. The base 2331 includes a ridge 2338 extending from the base 2331 engaged to the side wall of the staple cavity 2320. The interaction between the ridge 2338 and the side wall of the staple cavity prevents the staple 2330 from falling out of the bottom 2316 of the cartridge body 2310. The interaction between the ridge 2338 and the side wall of the staple cavity includes a tightening spring, which does not prevent the thread 2340 from ejecting the staple 2330 from the staple cavity 2320. The ridge 2338 can be formed within the base 2331, for example, during the punching process. The punching process can form a ridge 2338 by creating a recess 2337 on the opposite side of the base 2331. The staple cavity 2320 includes a flute 2328 aligned with the ridge 2338. The groove 2328 increases the contact area between the side wall of the staple cavity 2320 and the ridge 2338. In addition, the groove 2328 can control the orientation of the staples 2330 within the staple cavities 2320. An alternative embodiment that does not include the groove 2328 is recalled.

In addition to or instead of the above, the staples housed in the staple cartridges disclosed herein may include staple legs that are elastically engaged with the side walls of the staple cavities of the staples. Then, referring to FIG. 51, the staple 2430 may include a base 2431 and staple legs 2432 and 2433 extending from the base 2431. Staples 2430 are in many respects similar to staples 2130, 2330, and / or other staples disclosed herein. The staple cartridge body 2410 may include, for example, a plurality of staple cavities 2120 defined internally and staples 2430 located within each staple cavity 2120. FIG. 51 shows a staple 2430 positioned inside the cavity 2120 and a staple 2430 positioned outside the staple cavity 2120 of the cartridge body 2430. When the staples 2430 are not positioned within the staple cavities 2120, the staple legs 2432, 2433 do not extend in parallel, but rather the staple legs 2432, 2433 extend outward away from each other. When the staples 2430 are positioned within the staple cavities 2120, the staple legs 2432, 2433 are bent inward by the side walls of the staple cavities 2120. In other words, the staple legs 2432, 2433 are elastically urged against the side walls of the staple cavity, and this urging engagement prevents the staple 2430 from falling out of the bottom 2436 of the cartridge body 2410. Has been done. As shown in FIG. 51, the distance between the staple legs 2432 and 2433 when the staple 2130 is positioned in the staple cavity 2120 is X, and the staple when the staple 2130 is not positioned in the staple cavity. The distance between the legs 2432 and 2433 is greater than X.

In various embodiments, the cartridge body may include one or more shoulders that prevent the staples housed therein from falling out of the bottom of the cartridge body. The shoulders can extend at least partially under the staples.

In certain embodiments, the cartridge body of the staple cartridge assembly may be made of plastic or may be formed, for example, during an injection molding process. Injection molding may include two halves that can move towards and away from each other. The joint surface between the injection molded halves is often referred to as the dividing line, where the plastic flushing or seepage between the mold halves can often occur. In at least one embodiment, the injection molding dividing line may be defined at the junction surface between the deck of the staple cartridge and the staple cavity defined within the deck. As a result of the above, plastic flushing can occur around the staple cavity. Such flushing can keep the staples removable in the staple cartridge.

With reference to FIG. 48 again, the cartridge body 2310 is configured to engage directly with the jaw portion 2180. Jaw 2180 includes one or more internally defined holding shoulders 2315. The cartridge body 2310 includes a corresponding holding shoulder 2187 that, in cooperation with the holding shoulder 2315, holds the cartridge body 2310 removably within the jaw 2180. The cartridge body 2310 and / or jaw 2180 further includes an inclined surface surface 2314 configured to facilitate insertion of the cartridge body 2310 into the jaw 2180. As a result of the above, the cartridge body 2310 may have a snap-fitting relationship with the jaw portion 2180. The snap fit relationship can be overcome by pushing the cartridge body 2310 out of the jaw 2180 so that the staple cartridge assembly 2300 can be replaced.

Staples 2530 are shown in FIGS. 52-56. Staples 2530 are in many respects similar to staples 2130, 2330, 2340, and / or other staples disclosed herein. The staple 2530 includes a base 2531 and legs 2532 and 2533 extending from the base 2531. The staple 2530 also includes a protrusion 2538 that extends upward from the base 2531. The protrusion 2538 is aligned with the staple drive plane including the base 2531 and not with the tissue capture plane including the staple legs 2532 and 2533. The protrusion 2538 can pressurize the tissue outside the staple capture plane.

The staple cartridge assembly 2600 is shown in FIGS. 57-64. The staple cartridge 2600 includes a cartridge body 2610 that includes a plurality of staple cavities 2220 defined internally. The staple cartridge 2600 further includes a staple 2530 located within each staple cavity 2220 and a thread 2640 configured to eject the staple 2530 from the staple cavity 2220. Thread 2640 is similar to thread 2140 in many respects. Each thread 2640 includes a plurality of inclined surfaces 2645, each inclined surface 2645 including a drive surface 2641 configured to slide under the staples 2530 and lift the staples 2530 within the staple cavities 2220. Each drive surface 2641 includes an inclined surface 2643 defined by a lateral side wall 2649 that defines a guide channel for aligning the staple 2530 with respect to the drive surface 2641 and / or the staple cavity 2220. The guide channel is configured to receive the base 2531 of the staple 2530 between the side walls 2649 and to orient the staple 2530 laterally as the thread 2640 advances distally. Such lateral rearrangement is evident when comparing FIGS. 58 and 59. With reference to FIGS. 52-56 again, each staple 2530 includes a guide feature 2139 defined on its base 2531. The guide feature 2139 of each staple 2530 includes, for example, a curved end configured to interact with the lateral side wall 2649 of the guide channel to adjust the lateral position of the staple 2530. In various other embodiments, the guide feature 2139 may include any suitable configuration.

In addition to or instead of the above, mainly referring to FIG. 60, the thread 2640 receives the downwardly extending foot portion 2134 of the staple 2530 and staples 2530 to the drive surface 2641 and / or the staple cavity 2220.

In at least one example, it may be desirable for the elastic portion 3471 to have mechanical properties that closely resemble those of the patient's tissue. In another example, it may be desirable for the elastic portion 3471 to have a stiffness less than, for example, the stiffness of the patient tissue. Such embodiments may provide a suitable constriction of blood flow within the tissue. In some examples, it may be desirable for the elastic portion 3471 to have a stiffness less than, for example, the stiffness of the base 3631 but greater than the stiffness of the patient tissue. Such embodiments may provide tension relief to the tissue.

Accessories 3370, 3470 may be composed of a woven fabric material and / or a non-woven fabric material. In at least one example, the appendages 3370, 3470 include a shell composed of a woven fabric material and / or a non-woven material. Attachments 3370, 3470 may consist of, for example, PGA and / or PLA. In at least one example, the appendages 3370, 3470 include, for example, a shell composed of PGA and / or PLA.

The accessories 3370, 3470 are configured to be attached to a single staple. In other words, each accessory 3370, 3470 is attached to only one staple. Such accessories are sometimes referred to as pledgets. An alternative embodiment in which two or more staples are connected by an accessory is recalled.

Then, with reference to FIGS. 88 and 89, various staples disclosed herein, such as staples 2130, can be implanted in the patient's tissue in longitudinal columns. Two longitudinal rows of staples 2130 are shown in FIGS. 88 and 89. In various examples, the tissue may extend in various directions, for example in the longitudinal direction. The longitudinal extension of the tissue T is shown in FIG. As seen in FIG. 89, the rows of staples 2130 can extend with the tissue T. In such an example, the gap between the staples 2130 can increase. This increase in the gap is easily apparent when the distance X1 of the non-extended gap X1 (FIG. 88) is compared with the distance X2 of the extended gap (FIG. 89). The staples 2130 in the third longitudinal row are aligned with the gaps or have the same spread regardless of whether the gaps are extended (X2) or not (X1). Can be positioned and configured in. Such a concept can be easily adapted to, for example, circular and / or curved staple rows.

Next, referring to FIG. 87, for example, the circular cartridge body 3510 can utilize the staple assembly 3430. The cartridge body 3510 includes a plurality of staple cavities 3520 arranged in a circular concentric row. As shown in FIG. 87, each staple cavity includes an internally positioned staple assembly 3430, but any suitable staple can be utilized.

The entire disclosure of is incorporated herein by reference. In at least one example, the staples are composed of, for example, a magnesium alloy containing zinc and / or silver. Staples containing alloys of magnesium and zinc increase tissue healing performance. Staples containing silver provide an antibacterial effect. Staples containing all three alloys provide synergistic dynamics.

Staples made of magnesium, including those made of magnesium alloys, can be treated to improve the hardness of the staples. In various examples, a magnesium nitride coating can be applied to the magnesium staples. In certain examples, the magnesium nitride coating is applied to the entire magnesium staple, while in other examples, the magnesium nitride coating is applied to only a portion of the magnesium staple. For example, since the staple legs need to have sufficient hardness to penetrate the tissue, it may be desirable to coat only the staple legs and / or the tips of the staple legs with magnesium nitride. In at least one such example, when the magnesium nitride coating is applied to the staple legs, the mask can be applied to the rest of the magnesium staples. Magnesium nitride coatings can be made, for example, by introducing magnesium staples into a nitrogen-enriched environment at high temperature and / or high pressure.

In addition to or instead of the above, one or more surfaces of magnesium staples may contain a coating containing carbon.

In addition to or in place of the above, other surface hardening techniques can be utilized. For example, magnesium staples can be cured using a laser curing process and / or a plasma discharge curing process. In at least one example, a KERONITE ceramic surface treatment by Keronite International can be applied to the staples.

As mentioned above, certain parts of the magnesium staples may go through the hardening process, while other parts of the magnesium staples may not go through the hardening process. In some examples, certain parts of the magnesium staples may be hardened to a first hardness, while other parts of the magnesium staples may be hardened to a second hardness that is different from the first hardness. A portion of magnesium staples with lower hardness avoids magnesium, zinc, and / or silver ions faster than a portion of magnesium staples with higher hardness.

In addition to or instead of the above, magnesium staples, including those made of magnesium alloys, are at least partially covered with a coating containing silver. In at least one example, the silver coating may include, for example, ionized silver. In certain examples, an electroplating process can be utilized to apply a silver coating to the magnesium staples. In various examples, the entire magnesium staple is covered with a silver coating. In at least one example, a portion (s) of magnesium staples are masked during the electroplating process so that the masked portion is not or at least substantially uncoated with silver.

In addition to or instead of the above, the staples disclosed herein can be coated with an antibacterial coating or at least partially coated. Such coatings may include, for example, triclosan. In at least one example, triclosan is mixed in the absorbent polymer coating. In certain examples, the coating may include, for example, LAE mixed with sodium stearate. The entire disclosure of International Publication No. 2012013577 (A1) by Gaffar et al., entitled COMPOSITION FOR COATING MEDICAL DEVICES CONTAINING LAE AND A POLYCATIONIC AMPHOTERIC POLYMER, is incorporated herein by reference.

Then, with reference to FIGS. 90-92, the staple 3730 includes a metal frame and a coating 3739 on less than the entire metal frame. The metal frame includes staples 2130 and is composed of, for example, magnesium and / or magnesium alloy. The coating 3739 comprises a bioabsorbable polymer, but the coating 3739 may contain any suitable material. The coating 3739 extends around the legs 2132, 2133 of the metal frame 2130. More specifically, the coating 3739 spirals around each of the legs 2132, 2133, although any suitable arrangement of the coating 3739 may be utilized. The coating 3739 also covers the transitions or corners between the legs 2132, 2133 and the base or crown 2131 of the metal frame 2130. The coating 3739 may also cover a portion of the base 2131. In various examples, the coating 3739 is strategically applied to areas of the metal frame 2130 that are inherently susceptible to faster bioabsorption, such as bends, edges, and / or corners of the metal frame 2130. Can be done. In each case, a portion of the metal frame 2130 is covered by the coating 3739, while a portion of the metal frame 2130 is exposed.

The magnesium or magnesium alloy metal frame 2130 is bioabsorbable. Primarily with reference to FIG. 91, a portion of the metal frame 2130 not covered by the coating 3739 is directly exposed to the body when implanted and is therefore immediately subjected to the body's natural absorption process. The portion of the metal frame 2130 covered by the coating 3739 is not directly exposed to the body, at least initially, when implanted. The coating 3739 protects, or at least somewhat protects, the metal frame 2130 it covers, delaying bioabsorption of such parts. Over time, the unprotected portion of the metal frame 2130 is bioabsorbed, leaving the portion of the metal frame 2130 protected by the coating 3739, primarily with reference to FIG. The coating 3739 can substantially enclose a portion of the metal frame 2130 covered by the coating 3739, at least until the coating 3739 itself is bioabsorbed and / or the metal frame 2130 is sufficiently degraded. At this point, the portion of the metal frame 2130 that the coating 3739 temporarily protected is exposed and can be bioabsorbed by the body.

The bioabsorbable polymer of the coating 3739 may be composed of, for example, PGA and / or PLA, but the coating 3739 is composed of any suitable material including, but not limited to, bioabsorbable and non-bioabsorbable polymers. May be done. In certain examples, coating 3739 comprises, for example, a non-crosslinked polymer. Such a polymer can cause expansion of the coating 3739 and enclose the sharp edges of the metal frame 2130 that are created when the metal frame 2130 deteriorates.

In various embodiments, the coating 3739 may be placed on the metal frame 2130 in a grid, mesh, and / or grid arrangement. In such an embodiment, the metal frame 2130 can be exposed in an opening in the grid, whereby the metal frame 2130 can be bioabsorbed in such an opening. As the metal frame 2130 begins to deteriorate, the grid-like coating 3739 can act as a net or cage, for example, to assemble fragments of the metal frame 2130 until at least the coating 3739 is bioabsorbed.

The coating 3739 can be applied to the metal frame 2130 in any suitable manner. In at least one example, the coating 3739 may be sprayed onto the metal frame 2130 such that the coating 3739 is applied in an irregular manner that creates irregular openings in which the metal frame 2130 can be bioabsorbed. In certain other examples, the coating 3739 can be applied in a pattern on the metal frame 2130. In at least one such example, the pattern may include a dot matrix pattern with islands of coating surrounded by exposed portions of the metal frame 2130.

In certain alternative embodiments, the staples may include two or more coatings. In at least one such example, for example, to expose different parts of the metal frame 2130 at different times during the healing process, the first coating can be bioabsorbed at a first rate and the second coating It can be bioabsorbed at a rate of 2. It is contemplated that such staples may still have uncovered parts, but all parts of the staples may be covered by at least one or more coatings.

The therapeutic effect provided by the materials disclosed herein is a function of the surface area of the staples exposed to the patient's body. Staples with a larger surface area can deliver a therapeutic effect that is faster than staples with a smaller surface area. Therefore, staples with a smaller surface area may provide a therapeutic effect that takes longer. Nevertheless, the surface area of the staples disclosed herein can be increased by introducing holes in the staples. For example, one or more holes or through holes can be made, for example, in the base or crown 2131 of staples 2130. Through-holes allow tissue to grow through staples 2130 and improve assimilation of staples 2130 into the body.
