Abstract
A semi-disposable surgical stapling instrument for the replacement of staple cartridges, as needed, in the course of an operation, and for the optional provision of a knife to cut tissue between staple rows. Propulsion of the stapling unit may be powered and controlled from the back of the instrument by either hand, as desired, during a surgical procedure with minimal generation of frictional or distorting forces. Economic materials of construction may be employed.
