ABSTRACT:
A surgical stapler, preferably in a single use disposable form, comprises a combination of a staple feeding mechanism and a staple forming mechanism secured in a frame and an actuating trigger functionally connected to both the stable feeding mechanism and the staple forming mechanism, wherein the staple feeding mechanism includes a rail to guide contained staples serially to a staple forming position and a shuttle in association with the rail as a movable staple retaining cover, the shuttle being functionally connected to the trigger for movement in the same direction and the same time as the staples. The rail includes a pair of spaced apart flexible members which support the next staple to be deformed but which flex to move out of the staple path at the onset of deformation. The staple after formation is positioned between the members so that there is no interference between the rail and the deformed staple.
