STAPLE CARTRIDGE FOR A CURVED CUTTER STAPLER

摘要

A surgical instrument adapted for applying a plurality of surgical fasteners to body tissue is provided, comprising an anvil, a cartridge housing containing a plurality of surgical fasteners and a knife. A firing mechanism associated with the cartridge housing ejects the surgical fasteners and the knife from the cartridge housing to be driven against the anvil and a cartridge module which the cartridge housing forms a part of. The cartridge module includes a driver for pushing staples out and a knife holder attached to the knife. The knife extends through slots in the driver and the cartridge housing. The knife holder includes a detent post, extending through a slot in the cartridge hosing, which contracts detent protrusion of the cartridge slot during the longitudinal travel of the knife and knife holder. The driver includes a detent post that contacts detent protrusions formed on the cartridge housing slot.
