Patent ID: 8245899

Claim:
A surgical fastener apparatus comprising: a. a handle, an elongated shaft having a proximal end attached to said handle and a distal end extending therefrom, an end effector comprising a pair of jaws pivoted at a proximal end thereof and movable between an open and closed position, and a cartridge containing a plurality of surgical fasteners, said cartridge attached to said end effector; b. an electrically powered actuator for deploying said surgical fasteners, said actuator comprising a power source and a motor, said actuator including an elongated member extending through said shaft and movable distally into said end effector for deploying said staples and proximally back out of said end effector; c. a trigger attached to said handle and having an open and closed position; and said trigger for activating said actuator when in said closed position; and d. an electrically activated reverse mechanism for moving said elongated member from a distal most position within said end effector to a proximal position, said electrically activated reverse mechanism moves said elongated member proximally, after said elongated member has moved to said distal most position, by moving said trigger back to said open position, and wherein after activation of said reverse mechanism and while said reverse mechanism is moving said trigger back to said open position, proximal movement of said elongated member can be stopped by returning said trigger to its closed position.
