Abstract
A cartridge assembly and a surgical stapler are provided. The cartridge assembly includes: a cartridge including a cartridge surface provided with a plurality of staple cavities, staple mating portions provided on proximal sides of the staple cavities; a plurality of staples located in the staple cavities; an actuation member configured to drive the staples and the staple mating portions to rotate in a first direction when the actuation member moves from a proximal side toward a distal side of the cartridge. After each staple mating portion rotates, the second connecting portion of the corresponding staple is driven by the staple mating portion to move away from the cartridge and then separates from the staple cavity, so the staples can be more easily separated with the cartridge after being closed.
