CIRCULAR SURGICAL STAPLING DEVICE INCLUDING BUTTRESS MATERIAL
First Claim
1. A surgical stapling device for joining tissue portions, comprising:
- a handle assembly;
a tubular body portion supported on a distal end of the handle assembly, the tubular body portion having a staple cartridge assembly containing a plurality of surgical staples within a pair of annular arrays of staple receiving slots formed in a tissue facing surface thereof, the staple cartridge assembly defining a radial inner surface and a radial outer surface;
an anvil assembly at a distal end of the surgical stapling device, the anvil assembly having a shaft for removably connecting the anvil assembly to the tubular body portion, the anvil assembly and tubular body portion being juxtaposed with respect to one another along the shaft and arranged so as to be approximated with respect to one another;
a ring-like mounting structure sized to have an outer diameter that frictionally engages the radial inner surface of the staple cartridge assembly, wherein the mounting structure is disposed within the radial inner surface of the staple cartridge assembly;
an annular buttress material overlaying the tissue facing surface of the staple cartridge assembly, the annular buttress material defining an outer radial terminal edge extending radially beyond the pair of annular arrays of staple receiving slots, and a radial inner terminal edge extending across the mounting structure; and
at least one suture securing the buttress material to the mounting structure.

19. A method of using a buttress material and mounting structure assembly for use with a circular surgical stapling device including a staple cartridge assembly containing a plurality of surgical staples within a pair of annular arrays of staple receiving slots formed in a tissue facing surface thereof, the staple cartridge assembly defining a radial inner surface and a radial outer surface, the method comprising the steps of:
-
providing a buttress material and mounting structure assembly including; a ring-like mounting structure sized to have an outer diameter that frictionally engages the radial inner surface of the staple cartridge assembly; an annular buttress material overlaying the tissue facing surface of the staple cartridge assembly, the annular buttress material defining an outer radial terminal edge and a radial inner terminal edge; and at least one suture securing the buttress material to the mounting structure; positioning the buttress material and mounting structure assembly at least partially within the cartridge assembly of the surgical stapling device such that; the mounting structure is disposed within the radial inner surface of the staple cartridge assembly; and the outer radial terminal edge of the annular buttress material extends radially beyond the pair of annular arrays of staple receiving slots, and the radial inner terminal edge of the annular buttress material extends across the mounting structure; receiving body tissue between the anvil assembly and the cartridge assembly; grasping the body tissue between the anvil assembly and the cartridge assembly; and firing the surgical stapling device to; drive a plurality of staples from the staple cartridge assembly through the buttress material and the body tissue; and sever the buttress material radially outward of the at least one suture. - View Dependent Claims (20)
