Abstract

In various embodiments, a layer of material can comprise a body, a proximal end portion, and a distal end portion. The proximal end portion can be releasably secured to a staple cartridge of a surgical end effector, and the distal end portion can be releasably secured to an anvil of the surgical end effector. The layer of material can comprise a tissue thickness compensator.

Claims

1. A surgical end effector, comprising:

a staple cartridge comprising a staple;

an anvil moveable relative to said staple cartridge, wherein said anvil comprises a staple forming surface; and

a layer of material comprising;

a proximal end portion, wherein said proximal end portion is releasably secured to said staple cartridge; and

a distal end portion, wherein said distal end portion is releasably secured to said anvil.

2. The surgical end effector of claim 1, wherein said layer of material comprises a tissue thickness compensator.

3. The surgical end effector of claim 1, wherein said staple cartridge further comprises a first tissue contacting surface, and wherein said layer of material further comprises a second tissue contacting surface.

4. The surgical end effector of claim 1, wherein said staple cartridge further comprises a proximal end and a slot extending from said proximal end, and wherein said proximal end portion of said layer of material is releasably received in said slot.

5. The surgical end effector of claim 4, further comprising a firing element configured to move along at least a portion of said slot, wherein said firing element is configured to deform said proximal end portion.

6. The surgical end effector of claim 1, wherein said anvil further comprises a distal end and a slot extending from said distal end, and wherein said distal end portion of said layer of material is releasably received in said slot.

7. The surgical end effector of claim 1, wherein said proximal end portion further comprises a first deformable clip, and wherein said distal end portion further comprises a second deformable clip.

8. A surgical end effector, comprising:

a staple cartridge comprising a plurality of staples and a cartridge slot defined at least partially through said staple cartridge;

an anvil comprising an anvil slot defined at least partially through said anvil; and

a layer of material comprising;

a first attachment portion, wherein said cartridge slot is configured to receive said first attachment portion; and

a second attachment portion, wherein said anvil slot is configured to receive said second attachment portion.

9. The surgical end effector of claim 8, wherein said layer of material is removably attached to said staple cartridge and said anvil.

10. The surgical end effector of claim 9, further comprising a firing member configured to translate along said cartridge slot, wherein said firing member is configured to deflect said first attachment portion.

11. The surgical end effector of claim 8, wherein said first attachment portion extends from a proximal end of said layer of material, and wherein said second attachment portion extends from a distal end of said layer of material.

13. The surgical end effector of claim 8, wherein the first attachment portion comprises a deflectable hook.

14. The surgical end effector of claim 8, wherein said layer of material comprises a tissue thickness compensator.

15. A surgical end effector, comprising:

holding means for holding fasteners;

clamping means for clamping tissue between said clamping means and said holding means; and

a layer of material, comprising;

a proximal means for releasably attaching said layer of material to said holding means; and

a distal means for releasably attaching said layer of material to said clamping means.

16. The surgical end effector of claim 15, wherein said layer of material comprises tissue compensation means for compensating.

17. The surgical end effector of claim 15, further comprising releasing means for releasing said layer of material from at least one of said holding means or said clamping means.

18. The surgical end effector of claim 15, wherein said proximal means comprises a deflectable clip.

19. The surgical end effector of claim 18, wherein said holding means further comprises a plurality of fasteners and a slot configured to receive said deflectable clip.

20. A staple cartridge assembly for use with a surgical instrument, the staple cartridge assembly comprising:

a staple cartridge comprising;

a cartridge body; and

a plurality of staples at least partially positioned in said cartridge body; and

a layer of material comprising;

a proximal end portion, wherein said proximal end portion is releasably secured to said staple cartridge; and

a distal end portion, wherein said distal end portion is releasably securable to an anvil of the surgical instrument.

21. The staple cartridge assembly of claim 20, wherein said layer of material comprises a tissue thickness compensator.

22. The staple cartridge assembly of claim 20, wherein said cartridge body further comprises a tissue contacting deck, and wherein said layer of material further comprises a tissue contacting surface.

23. The staple cartridge assembly of claim 20, wherein said cartridge body comprises a proximal end and a slot extending from said proximal end, and wherein said proximal end portion of said layer of material is releasably received in said slot.

24. The staple cartridge assembly of claim 23, further comprising a firing element configured to move along at least a portion of said slot, wherein said firing element is configured to deform said proximal end portion.
