Abstract

See full text

A stapler and cartridge for joining together layers of body tissues. In a first aspect of the invention, a pair of handles, pivotally connected between opposite end portions, open a pair of jaws when the handles are rotatably moved apart and close the jaws when the handles are rotatably brought together. A detent is provided which assists a surgeon in properly clamping the layers of tissue before firing the staples through the tissues. A disposable cartridge is detachably mounted in one of the jaws by a pair of rails which slidably engage a pair of channels in one of the jaws and a convex boss which forcibly engages an aperture of the jaw. The cartridge is comprised of a staple retaining member and a staple unloading member. During a firing and clinching of the staples the cartridge members are telescoped together such that the size of the cartridge is reduced. In a second aspect of the invention, end portions of a pair of pivotally connected handles form jaws. In a third aspect of the invention a pair of pivotally connected jaws are connected to a pair of handles by a pair of short links and a long slender rod.
