Abstract
The present invention discloses a staple cartridge assembly and a medical stapler using the staple cartridge assembly. A first jaw is provided with a limiting portion; a cutter is provided with a securing portion; when a firing block is located at a proximal end of a staple cartridge assembly, a cutting push rod drives the cutter and the firing block together to move; when the firing block is located at the distal end of the staple cartridge assembly, a driving mechanism drives the cutter and the first jaw to move relative to each other; and the limiting portion and the securing portion resist against each other to restrict the cutter from continuing moving toward the distal end of the staple cartridge assembly. As a result, doctors can be effectively prevented from closing the stapler when the replacement of the fired staple cartridge assembly is not completed.
