Surgical stapling apparatus
A loading unit for use with a surgical stapling apparatus is provided and includes a tool assembly having a cartridge assembly and an anvil assembly that are movable in relation to one another; a surgical buttress releasably secured to a tissue contacting surface of the anvil assembly and/or the cartridge assembly, wherein each surgical buttress is secured to the anvil assembly and/or the cartridge assembly by at least one anchor; a release assembly associated with the anvil assembly and/or the cartridge assembly; and a drive assembly slidably translatable through the tool assembly between proximal and distal positions, wherein the drive assembly actuates the release assembly to thereby release the anchor to free the surgical buttress from the anvil assembly and/or the cartridge assembly.
1. A method of attaching a surgical buttress to a surgical instrument, comprising:
providing a surgical instrument including a cartridge assembly and an anvil assembly;
providing at least one surgical buttress;
providing at least one connecting member;
extending the connecting member across the at least one surgical buttress; and
securing the at least one connecting member to a constricting slot of one of the cartridge assembly and the anvil assembly.
2. The method of claim 1 , further comprising lying the at least one surgical buttress across a tissue contacting surface of one of the cartridge assembly and the anvil assembly.
3. The method of claim 1 , wherein the constricting slot has a converging shape.
4. The method of claim 1 , wherein at least one of the cartridge assembly and the anvil assembly has a pair of constricting slots, and the at least one connecting member has a first and a second end.
5. The method of claim 4 , wherein the first end is secured to a first of the pair of constricting slots and the second end is secured to a second of the pair of constricting slots.
6. The method of claim 5 , wherein the first of the pair of constricting slots is wider than the second of the pair of constricting slots.
7. The method of claim 6 , wherein the second end is secured before the first end.
8. The method of claim 1 , wherein the surgical instrument includes a release assembly.
9. The method of claim 1 , wherein the at least one surgical buttress includes a surgical buttress for the cartridge assembly and a surgical buttress for the anvil assembly.
10. The method of claim 9 , further comprising securing the at least one connecting member to the constricting slot of the anvil assembly.
11. A method of attaching a surgical buttress to a surgical apparatus, comprising:
providing a surgical apparatus including a cartridge assembly and an anvil assembly;
providing at least one surgical buttress;
providing at least one fastener;
extending the fastener across the at least one surgical buttress; and
securing the at least one connecting member to a constricting slot of one of the cartridge assembly and the anvil assembly.
12. The method of claim 11 , further comprising lying the at least one surgical buttress across a tissue contacting surface of one of the cartridge assembly and the anvil assembly.
13. The method of claim 11 , wherein the constricting slot has a converging shape.
14. The method of claim 11 , wherein at least one of the cartridge assembly and the anvil assembly has a pair of constricting slots, and the at least one fastener has a first and a second end.
15. The method of claim 14 , wherein the first end is secured to a first of the pair of constricting slots and the second end is secured to a second of the pair of constricting slots.
16. The method of claim 15 , wherein the first of the pair of constricting slots is wider than the second of the pair of constricting slots.
17. The method of claim 16 , wherein the second end is secured before the first end.
18. The method of claim 11 , wherein the surgical apparatus includes a release assembly.
19. The method of claim 11 , wherein the at least one surgical buttress includes a surgical buttress for the cartridge assembly and a surgical buttress for the anvil assembly.
20. The method of claim 19 , further comprising securing the at least one fastener to the constricting slot of the anvil assembly.
