Structure containing wound treatment material
View Patent ↗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.
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.
