Abstract

A piece of buttress material and an end-effector of a surgical instrument including features which can aid a surgeon in properly and quickly attaching the piece of buttress material to the end-effector. In various embodiments, a piece of buttress material can include retention features which can be engaged with portions of an end-effector to releasably retain the piece of buttress material to at least a portion of the end-effector. Similarly, an end-effector can include features configured to engage portions of a piece of buttress material to releasably retain the piece of buttress material to the end-effector. In at least one embodiment, more than one piece of buttress material can be releasably retained to an end-effector.

Claims

1. A piece of buttress material configured to be positioned on an end-effector of a surgical instrument, wherein the end-effector includes at least one of an anvil having a face and a staple cartridge having a deck, the piece of buttress material comprising:

a surface; and

an adhesive on said surface, wherein said adhesive is un-activated, wherein said surface is configured to be positioned against one of the face and the deck, and wherein a reactant is configured to be applied to said adhesive to activate said adhesive and releasably attach said surface to one of the face and the deck.

2. The piece of buttress material of claim 1, wherein said adhesive includes a hydro-stable material.

3. The piece of buttress material of claim 1, wherein said adhesive and the reactant together form a binary adhesive.

4. The piece of buttress material of claim 1, further comprising:

a body portion, wherein said body portion includes said surface;

a handle portion extending from said body portion; and

a perforation defined intermediate said handle portion and said body portion, wherein said handle portion is configured to be separated from said body portion along said perforation.

5. The piece of buttress material of claim 4, further comprising a recess defined intermediate said body portion and said handle portion, wherein said perforation is defined within said recess.

6. The piece of buttress material of claim 1, further comprising:

a body portion, wherein said body portion includes said surface;

a handle portion extending from said body portion;

a recess defined intermediate said body portion and said handle portion, wherein said recess is configured to receive the reactant.

7. A surgical accessory kit for use with an end-effector of a surgical instrument, the kit comprising:

a piece of buttress material having a surface;

an un-activated adhesive on at least a portion of said surface; and

a reactant configured to activate said adhesive and releasably attach said piece of buttress material to at least a portion of the end-effector.

8. The surgical accessory kit of claim 7, further comprising:

a handle portion extending from said piece of buttress material; and

a perforation defined intermediate said piece of buttress material and said handle portion, wherein said handle portion is configured to be separated from said piece of buttress material along said perforation.

9. The surgical accessory kit of claim 8, further comprising a recess defined intermediate said handle portion and said piece of buttress material, wherein said perforation is defined within said recess.

10. The surgical accessory kit of claim 7, further comprising:

a handle portion extending from said piece of buttress material; and

a recess defined intermediate said handle portion and said piece of buttress material, wherein said recess is configured to receive said reactant.

11. The surgical accessory kit of claim 7, wherein said adhesive includes a hydro-stable material.

12. The surgical accessory kit of claim 7, wherein said adhesive and said reactant together form a binary adhesive.

13. An end-effector assembly for use with a surgical instrument, the end-effector assembly comprising:

an anvil;

a staple cartridge; and

a piece of buttress material including an adhesive, wherein said adhesive is un-activated, wherein said piece of buttress material is configured to be positioned intermediate said anvil and said staple cartridge, and wherein a reactant is configured to be applied to said adhesive to activate said adhesive and releasably attach said piece of buttress material to one of said anvil and said staple cartridge.

14. The end-effector assembly of claim 13, wherein said adhesive includes a hydro-stable material.

15. The end-effector assembly of claim 13, wherein said adhesive and said reactant together form a binary adhesive.

16. The end-effector assembly of claim 13, wherein one of said anvil and said staple cartridge further comprises a portion configured to receive the reactant.

17. The end-effector assembly of claim 13, further comprising:

a handle portion extending from said piece of buttress material; and

a perforation defined intermediate said handle portion and said piece of buttress material, wherein said handle portion is configured to be separated from said piece of buttress material along said perforation.

18. The end-effector assembly of claim 17, further comprising a recess defined intermediate said piece of buttress material and said handle portion, wherein said recess is configured to receive said reactant.

19. The end-effector assembly of claim 13, further comprising:

a handle portion extending from said piece of buttress material;

a recess defined intermediate said piece of buttress material and said handle portion, wherein said recess is configured to receive the reactant.
