Abstract
A medical stapler including a ram adapted to push a staple along a passageway from an inlet opening into which staples are fed, to an outlet opening where the staple is ejected and closed about an anvil portion. A manually activated drive mechanism is adapted to move the ram and staple from the inlet to the outlet opening, will leave the ram across the outlet opening to prevent another staple from being fed into the channel if manual activation of the stapler is discontinued before the staple is ejected, and will couple the ram to the drive mechanism when the ram reaches its eject position so that the ram will subsequently be retracted with the drive mechanism. Also the stapler clicks when the ram reaches its eject position to provide both an audible and tactile indication that the staple has been fully closed.
