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 an annular surgical stapling apparatus, the end effector comprising:

a staple cartridge assembly having a tissue contacting surface defining a central aperture and a plurality of staple retaining slots in an annular configuration, each staple retaining slot of the plurality of staple retaining slots including a staple disposed therein;

an anvil assembly movable relative to the staple cartridge assembly;

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

an adhesive tape disposed between the surgical buttress and the tissue contacting surface of the staple cartridge assembly without covering the plurality of staple retaining slots of the staple cartridge assembly, the adhesive tape having;

a first adhesive bond with the tissue contacting surface of the staple cartridge assembly; and

a second welded bond with the surgical buttress for retaining the surgical buttress atop the tissue contacting surface of the staple cartridge assembly,

wherein a firing force of the staples from the staple cartridge assembly breaks the second welded bond between the surgical buttress and the adhesive tape.

2. The end effector of claim 1, wherein the adhesive tape has an annular configuration.

3. The end effector of claim 1, wherein the adhesive tape is secured to an inner portion of the tissue contacting surface of the staple cartridge assembly surrounding the central aperture.

4. A staple cartridge assembly for use with an annular surgical stapling apparatus, the staple cartridge assembly comprising:

a cartridge body including a tissue contacting surface defining a central aperture and a plurality of staple retaining slots in an annular configuration;

a staple disposed within each staple retaining slot of the plurality of staple retaining slots of the cartridge body;

a surgical buttress releasably attached to the tissue contacting surface of the cartridge body; and

an adhesive tape disposed between the surgical buttress and the tissue contacting surface of the cartridge body without covering the plurality of staple retaining slots of the cartridge body, the adhesive tape having;

a first adhesive bond with the tissue contacting surface of the cartridge body; and

a second welded bond with the surgical buttress for retaining the surgical buttress atop the tissue contacting surface of the cartridge body,

wherein a firing force of the staples from the cartridge body breaks the second welded bond between the surgical buttress and the adhesive tape.

5. The staple cartridge of claim 4, wherein the adhesive tape has an annular configuration.

6. The staple cartridge of claim 4, wherein the adhesive tape is secured to an inner portion of the tissue contacting surface of the cartridge body surrounding the central aperture.

7. An annular surgical stapling apparatus, comprising:

a tubular body including a distal end portion;

an end effector disposed at the distal end portion of the tubular body, the end effector including a staple cartridge assembly having a tissue contacting surface defining a central aperture and a plurality of staple retaining slots in an annular configuration, and an anvil assembly removably coupled to the distal end portion of the tubular body and movable relative to the staple cartridge assembly;

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

an adhesive tape disposed between the surgical buttress and the tissue contacting surface of the staple cartridge assembly, without covering the plurality of staple retaining slots of the staple cartridge assembly, the adhesive tape having;

a first adhesive bond with the tissue contact surface of the staple cartridge assembly; and

a second welded bond with the surgical buttress to retain the surgical buttress atop the tissue contacting surface of the staple cartridge assembly,

wherein a firing force of the annular surgical stapling apparatus breaks the second welded bond between the surgical buttress and the adhesive tape.

8. The annular surgical stapling apparatus of claim 7, wherein the adhesive tape has an annular configuration.

9. The annular surgical stapling apparatus of claim 7, wherein the adhesive tape is secured to an inner portion of the tissue contacting surface of the staple cartridge assembly surrounding the central aperture.
