soft bioabsorbable polymer adhesive for removably attaching a staple buttress to a surgical stapler

摘要

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