Malleable bioabsorbable polymer adhesive for releasably attaching a staple buttress to a surgical stapler

摘要

A surgical stapler end effector comprises a staple cartridge, an anvil, and a buttress assembly. The staple cartridge comprises a plurality of staples and a deck. The staple cartridge is operable to drive the staples through the deck. The anvil is movable from an open position toward the staple cartridge to reach a closed position. The anvil includes an underside having staple forming surface configured to receive staples driven through the deck. The buttress assembly comprises a buttress body and an adhesive material. The adhesive material is configured to removably secure the buttress body to the deck of the staple cartridge or the underside of the anvil. The adhesive material comprises a malleable bioabsorbable polymer.
