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. A switch configured to prevent application of firing motions to the end effector until the switch has been activated.

Claims

1. A surgical instrument system, comprising:

an end effector comprising a distal end, wherein said end effector is movable between an open configuration and a closed configuration when a closing motion is applied thereto;

a firing member movable toward said distal end when a firing motion is applied thereto;

a handle comprising a firing actuator;

a motor configured to generate said firing motion, wherein said firing actuator is operable to operate said motor; and

a switch configured to prevent application of said firing motion until said switch has been activated.
