Abstract

An end effector for a surgical stapling apparatus is provided which includes an anvil assembly and a surgical buttress. The anvil assembly includes an anvil body and an anvil plate. The anvil plate includes a bottom surface that defines a plurality of staple forming pockets. The anvil body and the anvil plate are selectively connectable. The surgical buttress includes a buttress body and a plurality of arms extending from the body. The arms are disposable between a top surface of the anvil plate and a bottom surface of the anvil body to support the buttress body against the bottom surface of the anvil plate when the anvil plate and the anvil body are connected to one another.

First claim

What is claimed is:

1. A surgical stapling instrument having an end effector, comprising:
a staple cartridge assembly having a plurality of surgical staples arranged in laterally spaced rows;
an anvil assembly including an anvil body and an anvil plate, the anvil plate including a bottom surface defining a plurality of staple forming pockets, the anvil body and the anvil plate being selectively connectable by securement features of the anvil body and the anvil plate, the anvil assembly including channels being defined by the anvil body and recessed from a bottom surface of the anvil body, the channels extending in a lateral direction; and
a surgical buttress including a buttress body and a plurality of arms extending from the body, the arms being disposed in and supported by the channels between the anvil plate and the anvil body to support the buttress body against the bottom surface of the anvil plate when the anvil plate and the anvil body are connected to one another.

2. The surgical stapling instrument of claim 1 , wherein the surgical buttress is formed of a non-woven material.

3. The surgical stapling instrument of claim 2 , wherein the surgical buttress is made from a material selected from the group comprising polyglytone 6211, glycolide, caprolactone, trimethylene carbonate, lactide and combinations thereof.

4. The surgical stapling instrument of claim 1 , wherein the arms of the surgical buttress are integrally formed with the buttress body.

5. The surgical stapling instrument of claim 1 , wherein the arms of the surgical buttress extend from side edges of the buttress body.

6. The surgical stapling instrument of claim 5 , wherein the arms of the surgical buttress are foldable over an outer side surface of the anvil plate to facilitate securement of the arms between a top surface of the anvil plate and the bottom surface of the anvil body.

7. The surgical stapling instrument of claim 1 , further comprising a knife that translates through the end effector to cut the surgical buttress.
