Abstract

The present disclosure describes an anvil assembly for a circular stapling apparatus. The anvil assembly includes an anvil head configured to support an anvil plate thereon; a shaft extending from the anvil head and configured to selectively engage a connection member of the circular stapling apparatus; an anvil plate operatively connected to the anvil head, the anvil plate defining a plurality of staple forming pockets therein; and a wound treatment material disposed in each staple forming pocket of the anvil plate. The wound treatment material is at least one of an adhesive, a sealant, a hemostat and a medicament.

Claims

1. An anvil assembly for a circular stapling apparatus, the anvil assembly comprising:

an anvil head configured to support an anvil plate thereon;

a shaft extending from the anvil head and configured to selectively engage a connection member of the circular stapling apparatus;

the anvil plate operatively connected to the anvil head, the anvil plate defining a plurality of staple forming pockets therein; and

a wound treatment material disposed within each of the plurality of staple forming pockets of the anvil plate, wherein the wound treatment material is at least one of an adhesive, a sealant, a hemostat and a medicament, and a liner at least partially extending over the anvil plate to retain the wound treatment material within each of the plurality of staple forming pockets prior to a firing of the circular stapling apparatus.

2. The surgical stapling apparatus according to claim 1, wherein the adhesive includes at least one of a protein derived, aldehyde-based adhesive material, and a cyanoacrylate-based material.

3. The surgical stapling apparatus according to claim 2, wherein the sealant material includes at least one of a fibrin sealant material, a collagen-based and synthetic polymer-based tissue sealant material, and synthetic polyethylene glycol-based, hydrogel sealant material.

4. The surgical stapling apparatus according to claim 1, wherein the hemostat material includes at least one of a fibrin-based material, a collagen-based material, an oxidized regenerated cellulose-based material, a gelatin-based material, and a fibrinogen-thrombin material.

5. The surgical stapling apparatus according to claim 1, wherein the medicament includes at least one of drugs, enzymes, growth factors, peptides, proteins, dyes, and diagnostic agents.

6. The surgical stapling apparatus according to claim 1, wherein the liner is fabricated from bio-absorbable material.

7. The surgical stapling apparatus according to claim 1, wherein the liner is fabricated from a material which is ruptured by staples of the circular stapling apparatus.

8. The surgical stapling apparatus according to claim 1, wherein at least a portion of the liner remains in a patient'"'"'s body after use of the circular stapling apparatus.

9. A circular stapling apparatus, the comprising:

a tubular body portion having a connection member;

a staple cartridge assembly operably supported on the tubular body portion, the staple cartridge assembly having a plurality of staple retaining slots and a surgical staple in each of the staple retaining slots;

an anvil head configured to support an anvil plate thereon, the anvil plate defining a plurality of staple forming pockets in registration with the staple retaining slots;

a shaft extending from the anvil head and configured to selectively engage the connection member of the tubular body portion; and

a wound treatment material disposed within each of the plurality of staple forming pockets of the anvil plate, wherein the wound treatment material is at least one of an adhesive, a sealant, a hemostat and a medicament, and a liner to retain the wound treatment material within each of the plurality of staple forming pockets prior to a firing of the circular stapling apparatus.

10. The surgical stapling apparatus according to claim 9, wherein the adhesive includes at least one of a protein derived, aldehyde-based adhesive material, and a cyanoacrylate-based material.

11. The surgical stapling apparatus according to claim 10, wherein the sealant material includes at least one of a fibrin sealant material, a collagen-based and synthetic polymer-based tissue sealant material, and synthetic polyethylene glycol-based, hydrogel sealant material.

12. The surgical stapling apparatus according to claim 9, wherein the hemostat material includes at least one of a fibrin-based material, a collagen-based material, an oxidized regenerated cellulose-based material, a gelatin-based material, and a fibrinogen-thrombin material.

13. The surgical stapling apparatus according to claim 9, wherein the medicament includes at least one of drugs, enzymes, growth factors, peptides, proteins, dyes, and diagnostic agents.

14. The surgical stapling apparatus according to claim 9, wherein the liner is fabricated from bio-absorbable material.

15. The surgical stapling apparatus according to claim 9, wherein the liner is fabricated from a material which is ruptured by staples of the circular stapling apparatus.

16. The surgical stapling apparatus according to claim 9, wherein at least a portion of the liner remains in a patient'"'"'s body after use of the circular stapling apparatus.
