Abstract

An end effector for use with a surgical apparatus. The end effector comprising a staple cartridge having a tissue contacting surface defining a central longitudinal slot and an anvil plate having a tissue contacting surface defining a central longitudinal slot. A surgical buttress releasably disposed on the tissue contacting surfaces of each of the staple cartridge and anvil plate. An adhesive tape is disposed over the central longitudinal slot of each of the staple cartridge and anvil plate and configured retain the respective surgical buttress atop the respective tissue contacting surface.

Claims

1. An end effector for use with a surgical stapling apparatus, the end effector comprising:

a staple cartridge assembly having a tissue contacting surface defining a central slot and a plurality of staple retaining slots;

an anvil assembly having a tissue contacting surface defining a central slot and a plurality of staple forming pockets;

a surgical buttress releasably attached to the tissue contacting surface of the anvil assembly; and

an adhesive tape disposed over the central slot of the anvil assembly and extending over edges of the tissue contacting surface defining the central slot without covering the plurality of staple forming pockets, the adhesive tape secured to the tissue contacting surface and the surgical buttress to retain the surgical buttress atop the tissue contacting surface of the anvil assembly.

2. The end effector of claim 1, wherein the adhesive tape has a welded bond with the surgical buttress.

3. The end effector of claim 2, wherein the adhesive tape has an adhesive bond with the tissue contacting surface of the anvil assembly.

4. The end effector of claim 1, wherein the adhesive tape extends longitudinally from a proximal end to a distal end of the tissue contacting surface of the anvil assembly.

5. The end effector of claim 1, further comprising a surgical buttress releasably attached to the tissue contacting surface of the staple cartridge assembly.

6. The end effector of claim 1, wherein the plurality of staple forming pockets are disposed on opposite sides of the central slot of the anvil assembly.

7. A surgical stapling apparatus, comprising:

an elongate tubular member;

an end effector disposed at a distal end of the elongate tubular member, the end effector including a staple cartridge assembly having a tissue contacting surface defining a central slot and a plurality of staple retaining slots, and an anvil assembly having a tissue contacting surface defining a central slot and a plurality of staple forming pockets;

a surgical buttress releasably attached to the tissue contacting surface of the anvil assembly; and

an adhesive tape disposed over the central slot of the anvil assembly and extending over edges of the tissue contacting surface defining the central slot without covering the plurality of staple forming pockets, the adhesive tape secured to the tissue contacting surface and the surgical buttress to retain the surgical buttress atop the tissue contacting surface of the anvil assembly.

8. The surgical stapling apparatus of claim 7, wherein the adhesive tape has a welded bond with the surgical buttress.

9. The surgical stapling apparatus according to claim 8, wherein the adhesive tape has an adhesive bond with the tissue contacting surface of the anvil assembly.

10. The surgical stapling apparatus according to claim 7, wherein the adhesive tape extends longitudinally from a proximal end to a distal end of the tissue contacting surface of the anvil assembly.

11. The end effector of claim 7, further comprising a surgical buttress releasably attached to the tissue contacting surface of the staple cartridge assembly.

12. The end effector of claim 7, wherein the plurality of staple forming pockets are disposed on opposite sides of the central slot of the anvil assembly.

13. An end effector for use with a surgical stapling apparatus, the end effector comprising:

a staple cartridge assembly having a tissue contacting surface defining a central slot and a plurality of staple retaining slots;

an anvil assembly having a tissue contacting surface defining a plurality of staple forming pockets;

a surgical buttress releasably attached to the tissue contacting surface of the cartridge assembly or the anvil assembly; and

an adhesive tape having an adhesive bond with the tissue contacting surface of the cartridge assembly or the anvil assembly and does not cover the plurality of staple retaining slots of the cartridge assembly or the plurality of staple forming pockets of the anvil assembly, and a welded bond with the surgical buttress for retaining the surgical buttress atop the tissue contacting surface of the staple cartridge assembly or the anvil assembly.

14. The end effector of claim 13, wherein each staple retaining slot of the plurality of staple retaining slots of the staple cartridge assembly includes a staple disposed therein, and wherein a firing force of the staples from the staple cartridge assembly breaks the welded bond between the surgical buttress and the adhesive tape.

15. The end effector of claim 13, wherein the adhesive tape extends longitudinally from a proximal end to a distal end of the tissue contacting surface of the staple cartridge assembly or the anvil assembly.

16. The end effector of claim 13, wherein the adhesive tape has an annular configuration.

17. The end effector of claim 13, wherein the plurality of staple forming pockets are disposed on opposite sides of the central slot of the anvil assembly, and wherein the plurality of staple retaining slots are disposed on opposite sides of the central slot of the staple cartridge assembly.
