Abstract

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.

Claims

1. A method for joining a pair of opposed tissues, the method comprising the steps of:

positioning a surgical stapling apparatus within a surgical site, the surgical stapling apparatus including;

a staple cartridge assembly having a plurality of staple retaining slots and a surgical staple in each of the staple retaining slots;

an anvil head assembly configured to support an anvil plate thereon, the anvil plate defining a plurality of staple forming pockets in registration with the staple retaining slots, wherein a capsule containing a wound treatment material has been previously placed within each of the plurality of staple forming pockets, wherein the capsule is fixedly contained within the plurality of staple forming pockets; and

a wound treatment material disposed within each of the plurality of staple retaining slots of the staple cartridge assembly, wherein the wound treatment material is at least one of an adhesive, a sealant, a hemostat and a medicament;

approximating the pair of opposed tissues to be joined such that the pair of opposed tissues are positioned between the staple cartridge assembly and the anvil head assembly; and

firing the surgical stapling apparatus such that a quantity of the wound treatment material is dispensed onto a portion of tissue surrounding a backspan of the staples.

2. The method according to claim 1, further comprising the step of securing a first of the pair of opposed tissues to the anvil head assembly and securing a second of the pair of opposed tissues to the staple cartridge assembly with a suture prior to approximating the anvil head assembly in relation to the staple cartridge assembly.

3. The method according to claim 1, further comprising the step of irradiating tissue at the surgical site with an ultraviolet light to thereby activate the wound treatment material after being dispensed from the surgical stapling apparatus.

4. A method for joining a pair of opposed tissues, the method comprising the steps of:

positioning a surgical stapling apparatus within a surgical site, the surgical stapling apparatus including;

a staple cartridge assembly having a plurality of staple retaining slots and a surgical staple in each of the staple retaining slots;

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

a wound treatment material having been previously placed within each of the plurality of staple retaining slots of the staple cartridge assembly and having been previously placed 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;

placing a liner atop a surface of the anvil plate to thereby cover the staple forming pockets and to retain the wound treatment material therein;

approximating the pair of opposed tissues to be joined such that the pair of opposed tissues are positioned between the staple cartridge assembly and the anvil head assembly; and

firing the surgical stapling apparatus such that a quantity of the wound treatment material is dispensed onto a portion of tissue surrounding a backspan of the staples.

5. The method according to claim 4, further comprising the step of penetrating the liner via the surgical staples to thereby dispense the wound treatment material from the surgical stapling apparatus.

6. The method according to claim 4, further comprising the step of placing a liner atop a surface of the staple cartridge assembly to thereby cover the staple retaining slots thereof and to retain the wound treatment material therein.

7. The method according to claim 6, further comprising the step of penetrating the liner via the surgical staples to thereby dispense the wound treatment material from the surgical stapling apparatus.
