Abstract

A surgical fastener apparatus having a handle, an elongated shaft having a proximal end attached to the handle and a distal end extending therefrom. An end effector including a pair of jaws pivoted at a proximal end thereof and movable between an open and closed position. A cartridge containing a plurality of surgical fasteners, the cartridge attached to the end effector. An electrically powered actuator for deploying the surgical fasteners, the actuator including a power source and a motor. Means for electrically adjusting the amount of spacing between the jaws when the end effector is in the closed position.

Claims

1. 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;

c. Means for electrically adjusting the amount of spacing between said jaws when said end effector is in said closed position.
