Abstract

A stapling system comprising an anvil, a staple cartridge, a first buttress material, a first adhesive gel, a second buttress material, and a second adhesive gel is disclosed. The staple cartridge comprises a deck, a slot configured to receive a firing member, staple cavities defined in the deck, staple drivers, and staples removably stored in the staple cavities. The firing member moves through the staple cartridge during a firing stroke. The staple drivers are configured to drive the staples against the anvil during the firing stroke. A portion of each staple driver is lifted above the deck during the firing stroke. The first buttress material comprises a first film mesh layer. The first adhesive gel releasably holds the first film mesh layer to the staple cartridge. The second buttress material comprises a second film mesh layer. The second adhesive gel releasably holds the second film mesh layer to the anvil.

Claims

1. A stapling system, comprising:

an anvil;

a staple cartridge, comprising;

a deck;

a longitudinal slot configured to receive a firing member, wherein said firing member moves through said staple cartridge during a firing stroke;

staple cavities defined in said deck;

staple drivers; and

staples removably stored in said staple cavities, wherein said staple drivers are configured to drive said staples against said anvil during said firing stroke, and wherein a portion of each said staple driver is lifted above said deck during said firing stroke;

a first buttress material comprising a first film mesh layer;

a first adhesive gel for releasably holding said first film mesh layer to said staple cartridge;

a second buttress material comprising a second film mesh layer; and

a second adhesive gel for releasably holding said second film mesh layer to said anvil.

2. The stapling system of claim 1, wherein said first adhesive gel and said second adhesive gel comprise polyethylene glycol.

3. A stapling system for use with a surgical instrument, comprising:

an anvil;

a cartridge, comprising;

a deck;

a longitudinal slot configured to receive a firing member of the surgical instrument, wherein said firing member moves through said cartridge during a firing stroke;

staple cavities defined in said deck;

staple drivers; and

staples removably stored in said staple cavities, wherein said staple drivers are configured to drive said staples against said anvil during said firing stroke, and wherein a portion of each said staple driver is lifted above said deck during said firing stroke;

a first laminate scaffold releasably held on said cartridge, wherein said first laminate scaffold comprises;

a first film mesh layer; and

a first flowable adhesive releasably holding said first film mesh layer to said cartridge; and

a second laminate scaffold releasably held on said anvil, wherein said second laminate scaffold comprises;

a second film mesh layer; and

a second flowable adhesive releasably holding said second film mesh layer to said anvil.

4. The stapling system of claim 3, wherein said first flowable adhesive and said second flowable adhesive comprise polyethylene glycol.

5. A stapling system for use with a surgical instrument, comprising:

an anvil;

a cartridge, comprising;

a deck;

a longitudinal slot;

staple cavities;

staple drivers positioned in said staple cavities; and

staples positioned on said staple drivers, wherein said staple drivers are configured to drive said staples against said anvil during a firing stroke, and wherein a portion of each said staple driver is lifted above said deck during said firing stroke;

a first laminate scaffold positioned on said cartridge, wherein said first laminate scaffold comprises a first film mesh layer;

a first flowable adhesive for releasably holding said first film mesh layer to said cartridge;

a second laminate scaffold positioned on said anvil, wherein said second laminate scaffold comprises a second film mesh layer;

a second flowable adhesive for releasably holding said second film mesh layer to said anvil; and

a firing member configured to be received in said longitudinal slot of said cartridge, wherein said firing member is further configured to sequentially eject said staples from said cartridge during said firing stroke, and wherein said first laminate scaffold is configured to progressively release from said cartridge during said firing stroke.

6. The stapling system of claim 5, wherein said first flowable adhesive and said second flowable adhesive comprise polyethylene glycol.
