摘要：
The present invention discloses a staple cartridge assembly and a medical stapler using the staple cartridge assembly. The staple cartridge assembly comprises a cutting push rod, a first jaw, a second jaw, a firing block, a cutter and a driving mechanism. The first jaw is provided with a limiting portion at a proximal end； the cutter is provided with a securing portion； when the firing block is located at a proximal end of the staple cartridge assembly, the cutting push rod drives the cutter and the firing block together to move toward a distal end of the staple cartridge assembly； when the firing block is located at the distal end of the staple cartridge assembly, the 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. According to the present invention, the driving mechanism drives the cutter and the first jaw to move relative to each other, so that 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, thereby avoiding medical accidents or damages to normal tissues.
