Abstract
A cartridge for use in a stapler for driving staples during orthopedic surgery is described. The cartridge has a case comprising a first wall and side walls projecting from this first wall. The cartridge has inner guide surfaces intended to guide the movement of staples when they are ejected by the stapler, and these preferably include the top of extended projections from a spacer element which is snap fit to the case. Within the case are a stack of staples supported on a follower which pushes on the side of the stack of staples so as to sequentially present each one in turn in a position to be ejected by the stapler. The follower is centered and slidably mounted on a guidepost which helps the follower resist any tendency for misalignment of the follower within the case.
