Abstract

A surgical cutting and fastening instrument having an end effector including a housing for holding staples and a sled having a camming surface for ejecting the staples. The instrument has a main drive shaft assembly for pushing the sled through the housing to eject the staples. Also included is a motor operatively coupled to the actuation shaft. The motor includes a drive assembly. The instrument further includes a sensor in the drive assembly to measure an actuation load. The instrument further includes a sensor for measuring a power output of the motor. The instrument further includes a console for remote control of the motor, the console comprising hand manipulated controls. The instrument further includes a means for providing proportionate feedback from the sensors to the hand manipulated controls.

Claims
