Structure containing wound treatment material
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. A surgical stapling apparatus comprising:
a body portion having a connection member;
a staple cartridge assembly operably supported on the 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 body portion;
a wound treatment material disposed within the plurality of staple retaining slots of the staple cartridge assembly; and
at least one capsule, including a wound treatment material contained therein, adhered to the plurality of staple forming pockets of the anvil plate.
2. The surgical stapling apparatus according to claim 1 , wherein the wound treatment material is an adhesive including 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 cures upon application of pressure.
3. The surgical stapling apparatus according to claim 2 , wherein the adhesive includes at least one of a protein derived, aldehyde-based adhesive material, and a cyanoacrylate-based material.
4. The surgical stapling apparatus according to claim 1 , wherein the wound treatment material is a sealant material including 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.
5. The surgical stapling apparatus according to claim 1 , wherein the wound treatment material is a hemostat material including 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.
6. The surgical stapling apparatus according to claim 1 , wherein the wound treatment material is a medicament including at least one of drugs, enzymes, growth factors, peptides, proteins, dyes, and diagnostic agents.
7. The surgical stapling apparatus according to claim 1 , wherein the staple forming pockets are arranged in a pair of spaced apart concentric annular rings.
