Staple cartridge including a compressible member
A staple cartridge comprising a cartridge body, a surgical staple, and a compressible member is disclosed. The surgical staple is movable from an unfired position to a fired position. The surgical staple is deformable from a first shape in the unfired position to a second shape in the fired position during a firing stroke. The surgical staple is ejected from the cartridge body during the firing stroke. The surgical staple comprises a crown, a first deformable member extending from the crown, and a second deformable member extending from the crown. The compressible member is positioned intermediate the first deformable member, the second deformable member, and the crown after the surgical staple has been deformed into the second shape. The compressible member is at least partially positioned between the first deformable member and the second deformable member of the surgical staple when the surgical staple is in the unfired position.
1. A staple cartridge, comprising:
a cartridge body;
a surgical staple, wherein said surgical staple is movable from an unfired position to a fired position, wherein said surgical staple is deformable from a first shape in said unfired position to a second shape in said fired position during a firing stroke, wherein said surgical staple is ejected from said cartridge body during said firing stroke, and wherein said surgical staple comprises:
a crown;
a first deformable member extending from said crown; and
a second deformable member extending from said crown; and
a compressible member positioned intermediate said first deformable member, said second deformable member, and said crown after said surgical staple has been deformed into said second shape, wherein said compressible member is at least partially positioned between said first deformable member and said second deformable member of said surgical staple when said surgical staple is in said unfired position.
2. The staple cartridge of claim 1 , wherein said compressible member is comprised of foam.
3. The staple cartridge of claim 1 , further comprising a firing member configured to translate within said cartridge body to move said surgical staple from said unfired position to said fired position.
4. The staple cartridge of claim 1 , wherein said compressible member is configured to bias tissue positioned intermediate said compressible member and said first deformable member against said first deformable member.
5. The staple cartridge of claim 4 , wherein said compressible member is configured to bias the tissue against said second deformable member.
6. The staple cartridge of claim 1 , wherein at least one of said compressible member and said crown are comprised of a bioabsorbable material.
7. The staple cartridge of claim 1 , further comprising a firing member configured to translate within said cartridge body relative to said surgical staple to at least partially eject said surgical staple from said cartridge body.
8. A staple cartridge, comprising:
a cartridge body;
a surgical staple, wherein said surgical staple is movable from an undeployed position to a deployed position, wherein said surgical staple is deformable from a first shape in said undeployed position to a second shape in said deployed position during a firing stroke, wherein said surgical staple is ejected from said cartridge body during said firing stroke, and wherein said surgical staple comprises:
a crown;
a first deformable member extending from said crown; and
a second deformable member extending from said crown; and
a compressible member positioned intermediate said first deformable member, said second deformable member, and said crown after said surgical staple has been deformed into said second shape, wherein said compressible member is at least partially housed between said first deformable member and said second deformable member of said surgical staple when said surgical staple is in said undeployed position.
9. The staple cartridge of claim 8 , wherein said compressible member is comprised of foam.
10. The staple cartridge of claim 8 , further comprising a firing member configured to translate within said cartridge body to move said surgical staple from said undeployed position to said deployed position.
11. The staple cartridge of claim 8 , wherein said compressible member is configured to bias tissue positioned intermediate said compressible member and said first deformable member against said first deformable member.
12. The staple cartridge of claim 11 , wherein said compressible member is configured to bias the tissue against said second deformable member.
13. The staple cartridge of claim 8 , wherein at least one of said compressible member and said crown are comprised of a bioabsorbable material.
14. The staple cartridge of claim 8 , further comprising a firing member configured to translate within said cartridge body relative to said surgical staple to at least partially eject said surgical staple from said cartridge body.
15. A surgical stapling instrument, comprising:
an anvil;
a staple cartridge, wherein at least one of said anvil and said staple cartridge is movable to capture tissue between said anvil and said staple cartridge, and wherein said staple cartridge comprises:
a cartridge body; and
a surgical staple, wherein said surgical staple is movable from an undeployed position to a deployed position, wherein said surgical staple is deformable between a first shape in said undeployed position and a second shape in said deployed position during a firing stroke, wherein said surgical staple is ejected from said cartridge body during said firing stroke, and wherein said surgical staple comprises:
a crown;
a first deformable member extending from said crown; and
a second deformable member extending from said crown;
a firing member movable from a starting position to motivate said surgical staple to move from said undeployed position to said deployed position; and
a compressible member positioned intermediate said first deformable member, said second deformable member, and said crown after said surgical staple has been deformed into said second shape, wherein said compressible member is at least partially disposed between said first deformable member and said second deformable member of said surgical staple when said firing member is in said starting position.
16. The surgical stapling instrument of claim 15 , wherein said compressible member is comprised of foam.
17. The surgical stapling instrument of claim 15 , wherein said compressible member is configured to bias tissue positioned intermediate said compressible member and said first deformable member against said first deformable member.
18. The surgical stapling instrument of claim 17 , wherein said compressible member is configured to bias the tissue against said second deformable member.
19. The surgical stapling instrument of claim 15 , wherein at least one of said compressible member and said crown are comprised of a bioabsorbable material.
