Abstract

Systems of releasably connecting staple line buttress material to the jaws of a surgical stapling instrument are provided. The systems include retainers configured to engage the buttress material and releasably retain the buttress material on the jaws of the surgical stapling instrument prior to stapling tissue. In certain embodiments, the retainers remain with the jaws of the instrument after stapling of tissue. In alternative embodiments, the retainers remain with the buttress material after being stapled to tissue.

Claims

1. A surgical stapler instrument, comprising:

a surgical stapler instrument having a jaw assembly, the jaw assembly having an anvil and a staple cartridge, the staple cartridge having pockets arranged in rows;

a buttress material disposed over the staple cartridge, the buttress material being penetrable by a fastener;

at least one fastener inserted through the buttress material and into at least one of the pockets, a portion of the fastener retaining the buttress material, the fastener having legs that are crimped;

wherein a further fastener has legs that are inserted through the buttress material and through holes in the anvil.

2. The surgical stapler instrument according to claim 1, wherein said buttress material has preformed holes to receive the legs of the at least one fastener.

3. The surgical stapler instrument according to claim 1, wherein the at least one fastener is frictionally retained in the pocket and is detachable from the staple cartridge.

4. The surgical stapler instrument according to claim 1, wherein the at least one fastener is formed from an absorbable or resorbable material.

5. The surgical stapler instrument according to claim 1, wherein the at least one fastener has inwardly bent legs that are sufficiently short so that the buttress material can pull away from the at least one fastener.
