Buttress material for use with a surgical stapler
In various embodiments of the present invention, a piece of buttress material can be configured to match a curved profile of the anvil and/or staple cartridge of a surgical stapler. In at least one embodiment, the piece of buttress material can include first and second edges extending between first and second ends. In these embodiments, the first edge can be defined by a first radius of curvature and the second edge can be defined by a second radius of curvature wherein the second radius of curvature is larger than the first radius of curvature. In at least one embodiment, the anvil and/or staple cartridge can include a surface configured for receiving a piece of buttress material thereon and a lip which at least partially extends along the periphery thereof wherein the lip can be configured to reduce relative movement between the piece of buttress material and the surface.
1 . A surgical stapler, comprising:
a staple cartridge channel configured to receive a staple cartridge, the staple cartridge configured to removably store staples therein;
an anvil configured to deform said staples;
a surface configured to receive a piece of buttress material thereon, wherein said surface includes a first end, a second end, and a first edge extending between said first end and said second end, and wherein said first edge is at least partially defined by a first radius of curvature; and
a lip which at least partially extends along said first edge, wherein said lip is configured to reduce relative movement between said piece of buttress material and said surface.
2 . The surgical stapler of claim 1 , further including a second lip which at least partially extends along said first end.
3 . The surgical stapler of claim 1 , further including a second lip which at least partially extends along said second end.
4 . The surgical stapler of claim 1 , wherein said surface further includes a second edge extending between said first end and said second end, wherein said second edge is at least partially defined by a second radius of curvature, and wherein said surgical stapler further includes a second lip which at least partially extends along said second edge.
5 . The surgical stapler of claim 1 , further comprising said staple cartridge, wherein said staple cartridge includes said surface and said lip.
6 . The surgical stapler of claim 1 , further comprising said piece of buttress material.
7 . The surgical stapler of claim 6 , further comprising adhesive for securing said piece of buttress material to said surface.
8 . The surgical stapler of claim 1 , wherein said surgical stapler further comprises a second surface configured to receive a second piece of buttress material thereon and a second lip extending along the periphery of said second surface, and wherein said second lip is configured to reduce relative movement between said second piece of buttress material and said second surface.
9 . The surgical stapler of claim 7 , wherein said anvil includes said second surface and said second lip, and wherein said anvil further comprises a third surface configured to receive a third piece of buttress material thereon and a third lip extending along the periphery of said third surface.
10 . A method for processing an instrument for surgery, comprising:
obtaining the surgical stapler of claim 1 ;
sterilizing said surgical stapler; and
storing said surgical stapler in a sterile container.
11 . A surgical stapler assembly, comprising:
a surgical stapler, comprising:
a staple cartridge configured to removably store staples; and
an anvil configured to deform said staples, wherein said anvil and said staple cartridge are configured to deploy said staples in at least one curved row, and
a piece of buttress material including a first end, a second end, and a first edge extending between said first end and said second end, wherein said first edge is at least partially defined by a first radius of curvature, and wherein one of said anvil and said staple cartridge includes a surface configured to receive said buttress material thereon.
12 . The surgical stapler assembly of claim 11 , wherein said staple cartridge includes said surface and a lip, wherein said lip at least partially extends along said first edge, and wherein said lip is configured to reduce relative movement between said piece of buttress material and said surface.
13 . The surgical stapler assembly of claim 12 , wherein said surgical stapler further comprises a second piece of buttress material, wherein said anvil includes a second surface and a second lip extending along the periphery of said second surface, and wherein said second lip is configured to reduce relative movement between said second piece of buttress material and said second surface.
14 . The surgical stapler assembly of claim 11 , wherein said piece of buttress material is adhered to said surface.
15 . The surgical stapler assembly of claim 11 , wherein said piece of buttress material further comprises a plurality of perforations positioned along a second radius of curvature, and wherein said second radius of curvature is larger than said first radius of curvature.
16 . A piece of buttress material, comprising:
a first end;
a second end;
a first edge extending between said first end and said second end; and
a second edge extending between said first end and said second end, wherein said first edge is at least partially defined by a first radius of curvature.
17 . The piece of buttress material of claim 16 , wherein said second edge is at least partially defined by a second radius of curvature, and wherein said second radius of curvature is larger than said first radius of curvature.
18 . The piece of buttress material of claim 17 , further comprising a plurality of perforations positioned along a third radius of curvature, wherein said third radius of curvature is larger than said first radius of curvature, and wherein said second radius of curvature is larger than said third radius of curvature.
19 . A piece of buttress material, comprising:
a first end;
a second end;
a first edge extending between said first end and said second end, wherein said first edge is at least partially defined by a first radius of curvature;
a second edge extending between said first end and said second end; and
a plurality of perforations positioned along a second radius of curvature, wherein said second radius of curvature is larger than said first radius of curvature.
