A surgical instrument includes an end effector and a staple cartridge that is insertable into the end effector. The staple cartridge includes a buttress material that is selectively coupled to the staple cartridge. In some versions the buttress material may be stapled to the staple cartridge by one or more attachment staples. Such attachment staples may be inserted into staple apertures formed through an upper deck of the staple cartridge. The attachment staples may include resiliently biased legs to frictionally resist removal. In some versions the attachment staples may be sized to form an interference fit in the staple apertures. Alternatively, the attachment staples may include barbs. A staple driver may be used to decouple the attachment staples. The staple driver may include staple forming pockets to bend the legs of the attachment staple when decoupling the attachment staple.
1. An apparatus, comprising: (a) a surgical instrument, wherein the surgical instrument is operable to sever and staple a portion of tissue, wherein the surgical instrument comprises a distal end, and wherein the surgical instrument comprises an end effector at the distal end; and(b) a staple cartri
1. An apparatus, comprising: (a) a surgical instrument, wherein the surgical instrument is operable to sever and staple a portion of tissue, wherein the surgical instrument comprises a distal end, and wherein the surgical instrument comprises an end effector at the distal end; and(b) a staple cartridge, wherein the staple cartridge is selectively insertable into the end effector, the staple cartridge comprising: i. an upper deck,ii. a buttress material in communication with the upper deck, andiii. an attachment staple driver,wherein the buttress material is selectively coupled to the staple cartridge by one or more fasteners,wherein the attachment staple driver is operable to engage the one or more fasteners, and wherein the attachment staple driver is operable to decouple the one or more fasteners. 2. The apparatus of claim 1 wherein the one or more fasteners comprises an attachment staple, wherein the attachment staple selectively couples the buttress material to the upper deck. 3. The apparatus of claim 2 wherein the upper deck comprises an attachment staple aperture, wherein the attachment staple is inserted into the attachment staple aperture. 4. The apparatus of claim 3 wherein the attachment staple comprises a wire, wherein the wire has a diameter, wherein the attachment staple aperture has a width, and wherein the diameter of the wire is greater than the width of the attachment staple aperture. 5. The apparatus of claim 3 wherein the attachment staple comprises a wire, wherein the wire has a diameter, wherein the attachment staple aperture has a width, and wherein the diameter of the wire is substantially equal to the width of the attachment staple aperture. 6. The apparatus of claim 3 wherein the staple cartridge further comprises a plurality of staples and a plurality of staple drivers disposed therein, wherein the upper deck comprises a plurality of staple apertures, wherein each staple of the plurality of staples is in communication with a respective staple driver of the plurality of staple drivers. 7. The apparatus of claim 6 wherein the attachment staple aperture is longitudinally aligned with one or more of the staple apertures. 8. The apparatus of claim 6 wherein the plurality of staple drivers are operable to drive the plurality of staples through the buttress material. 9. The apparatus of claim 3 wherein the attachment staple driver is in communication with the attachment staple aperture. 10. The apparatus of claim 9 wherein the attachment staple driver is vertically translatable relative to the upper deck. 11. The apparatus of claim 9 wherein the attachment staple driver comprises staple forming pockets. 12. The apparatus of claim 2 wherein the attachment staple comprises a pair of resiliently biased legs. 13. The apparatus of claim 12, wherein the resiliently biased legs are biased outwardly. 14. The apparatus of claim 12 wherein the resiliently biased legs comprise barbs. 15. The apparatus of claim 1 wherein the buttress material is selected from a group consisting of: a hemostatic agent;thrombin; orfibrin. 16. An apparatus comprising: (a) a surgical instrument comprising an anvil, a lower jaw, and a firing bar having a cutting edge, wherein the anvil and the lower jaw are operable to secure a portion of tissue therebetween, wherein the firing bar is operable to advance distally relative to the anvil and lower jaw to cut the portion of tissue; and(b) a staple cartridge, wherein the staple cartridge is selectively insertable into the lower jaw, the staple cartridge comprising: i. a cartridge body,ii. an upper deck having a plurality of staple apertures formed therethrough,iii. a plurality of staple drivers, wherein each staple driver of the plurality of staple drivers is in communication with a respective staple aperture of the plurality of staple apertures,iv. one or more staples disposed in the cartridge body, wherein the one or more staples are in communication with one or more staple drivers of the plurality of staple drivers, andv. a buttress material in communication with the upper deck,wherein the buttress material is selectively coupled to the staple cartridge by at least one fastener; andwherein at least one staple driver of the plurality of staple drivers is operable to selectively decouple the buttress material from the staple cartridge. 17. The apparatus of claim 16 wherein the at least one fastener comprises a plurality of attachment staples, wherein each attachment staple of the plurality of attachment staples is inserted into a staple aperture. 18. The apparatus of claim 17 wherein each attachment staple of the plurality of attachment staples comprises a pair of resiliently biased legs. 19. The apparatus of claim 18 wherein the at least one staple driver of the plurality of staple drivers selectively engages the resiliently biased legs of at least one attachment staple of the plurality of attachment staples. 20. A method for selectively coupling a buttress material to a staple cartridge for a surgical instrument using one or more attachment members, wherein the surgical instrument comprises an end effector configured to receive the staple cartridge, wherein the end effector is operable to cut a portion of tissue and to staple a portion of tissue when the staple cartridge is inserted therein, wherein the staple cartridge comprises an upper deck having a plurality of staple apertures and a staple driver, the method comprising: (a) placing the buttress material on top of at least a portion of the upper deck; and(b) inserting the one or more attachment members through the buttress material and into at least one staple aperture of the plurality of staple apertures;wherein the insertion of the one or more attachment members selectively couples the buttress material to the staple cartridge, and wherein the staple driver is operable to selectively decouple the one or more attachment members.
