Structure containing wound treatment material
View Patent ↗According to an aspect of the present disclosure, an anvil assembly for a circular stapling apparatus, is disclosed. 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.
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;

a wound treatment material disposed within each staple forming pocket of the anvil plate, wherein the wound treatment material is at least one of an adhesive, a sealant, a hemostat and a medicament, wherein the wound treatment material is contained in a capsule, wherein each capsule is configured for retention within the staple forming pockets.
2. The anvil assembly according to claim 1 , wherein the wound treatment material is at least one of an adhesive, a sealant, a hemostat and a medicament.
3. The anvil assembly according to claim 2 , wherein the adhesive includes at least one of an adhesive which cures upon tissue contact, an adhesive which cures upon exposure to ultraviolet (UV) light, and an adhesive which is pressure sensitive.
4. The anvil assembly according to claim 2 , wherein the adhesive includes at least one of a protein derived, aldehyde-based adhesive material, and a cyanoacrylate-based material.
5. The anvil assembly 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.
6. The anvil assembly according to claim 2 , 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.
7. The anvil assembly according to claim 2 , wherein the medicament includes at least one of drugs, enzymes, growth factors, peptides, proteins, dyes, and diagnostic agents.
8. The anvil assembly according to claim 2 , further comprising a liner covering the plurality of staple forming pockets.
9. The anvil assembly according to claim 8 , wherein the staple forming pockets are arranged in a pair of spaced apart concentric annular rings.
10. The anvil assembly according to claim 9 , wherein the staple forming pockets are in registration with respective staple retaining slots formed in a staple cartridge assembly of the surgical stapling apparatus.
11. 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;
a wound treatment material disposed within each staple forming pocket of the anvil plate, wherein the wound treatment material is at least one of an adhesive, a sealant, a hemostat and a medicament, wherein the wound treatment material is contained in a capsule, wherein each capsule is configured for retention within the staple forming pockets.
12. The surgical stapling apparatus according to claim 11 wherein the wound treatment material is at least one of an adhesive, a sealant, a hemostat and a medicament.
13. The surgical stapling apparatus according to claim 11 , wherein the adhesive includes at least one of a protein derived, aldehyde-based adhesive material, and a cyanoacrylate-based material.
14. The surgical stapling apparatus according to claim 11 , 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.
15. The surgical stapling apparatus according to claim 11 , 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.
16. The surgical stapling apparatus according to claim 11 , wherein the medicament includes at least one of drugs, enzymes, growth factors, peptides, proteins, dyes, and diagnostic agents.
