Abstract
A disposable surgical stapler cartridge having a pair of partially engaged staple retaining and unloading members and a plurality of staples for joining together body tissues. Each staple has a center portion and a pair of adjoining downward extending side portions. Lower portions of the side portions are modified in cross-section to provide hinge points which reduce the required force for clinching the staples. The apertures of the cartridge retaining member require higher initial forces for unloading the staples from the member. The cartridge is detachably mounted in a jaw of a stapler by a pair of rails which slidably engage channels of the jaw and a boss which forcibly engages an aperture of the jaw. During a clinching of the staples the cartridge members are fully engaged to reduce the size of the cartridge.
