Abstract
Disclosed is an end effector for a stapler, including a knife holder, and a staple cartridge unit and a staple anvil which are pivotally connected to achieve relative opening and closing. The staple cartridge unit includes a staple cartridge base and a detachable staple cartridge assembly. The knife holder includes a knife holder body and a limiting projection. The limiting projection is arranged between the knife holder body and the knife holder body. When the staple cartridge assembly is detached or mounted relative to the staple cartridge base, the limiting projection of the knife holder abuts against a proximal end portion of the staple cartridge base to stop the staple cartridge base. When the knife holder leaves the initial retraction position, the limiting projection of the knife holder is separated from the staple cartridge base.
