Abstract

An apparatus for joining two hollow organ sections with an annular array of surgical staples includes a staple cartridge component, an anvil component, a buttress component and a fastening member. The staple cartridge component includes a plurality of surgical staples arranged in an annular array. The anvil component is movable relative to the staple cartridge component between spaced apart and approximated positions to adjustably clamp the organ sections between the staple cartridge and anvil components. The buttress component is configured and dimensioned to be positioned on a distal surface of the staple cartridge component. In particular, the buttress component includes a buttress member and a plurality of circumferentially arranged tabs extending proximally from the buttress member. The fastening member is configured and dimensioned to engage the plurality of circumferentially arranged tabs to securely position the buttress component on the staple cartridge component.

Claims

1. An apparatus for joining two hollow organ sections with an annular array of surgical staples, the apparatus comprising:

a staple cartridge component including a plurality of surgical staples arranged in an annular array and a plurality of circumferentially arranged attaching members disposed on an inner wall thereof;

an anvil component movable relative to the staple cartridge component between spaced apart and approximated positions to adjustably clamp the organ sections between the staple cartridge and anvil components;

a buttress component configured to be positioned on a distal surface of the staple cartridge component, the buttress component including a buttress member and a plurality of circumferentially arranged tabs extending proximally from the buttress member, each tab of the plurality of circumferentially arranged tabs including an attaching member on an outer wall thereof, wherein the attaching members of the plurality of circumferentially arranged tabs of the buttress component correspond to, and are configured to engage, the plurality of circumferentially arranged attaching members of the staple cartridge component to securely position the buttress component on the staple cartridge component; and

a cylindrical knife positioned radially outward of the attaching members of the plurality of circumferentially arranged tabs of the buttress component and radially inward of the plurality of circumferentially arranged attaching members of the staple cartridge assembly.

2. The apparatus according to claim 1, wherein the buttress component is configured such that the plurality of circumferentially arranged tabs engage the inner wall of the staple cartridge component.

3. The apparatus according to claim 1, wherein the buttress member is severably coupled to the plurality of circumferentially arranged tabs.

4. The apparatus according to claim 3, wherein the cylindrical knife is configured to sever the buttress member of the buttress component from the plurality of circumferentially arranged tabs of the buttress component.

5. The apparatus according to claim 3, wherein the buttress component further includes a perforation disposed between the buttress member and the plurality of circumferentially arranged tabs.

6. The apparatus according to claim 1, wherein the plurality of circumferentially arranged tabs of the buttress component extend proximally along an inner circumference of the buttress member.

7. An apparatus for joining two hollow organ sections, the apparatus comprising:

a staple cartridge component including a plurality of surgical staples;

an anvil component movable relative to the staple cartridge component between spaced apart and approximated positions;

a buttress component configured to be positioned on a distal surface of the staple cartridge component, the buttress component including a buttress member and a plurality of circumferentially arranged tabs extending proximally from the buttress member, the plurality of circumferentially arranged tabs engagable with an inner wall of the staple cartridge component; and

a cylindrical knife positioned radially outward of the plurality of circumferentially arranged tabs of the buttress component and radially inward of the inner wall of the staple cartridge component, the cylindrical knife configured to sever the buttress member from the plurality of circumferentially arranged tabs.
