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

1. A surgical cutting and fastening instrument comprising:

a. an end effector comprising a housing for holding staples, and a sled having a camming surface for ejecting the staples;

b. a main drive shaft assembly for pushing the sled through the housing to eject the staples;

c. a motor operatively coupled to an actuation shaft the actuation shaft housed within a rigid outer shaft, said motor comprising a drive assembly;

d. a sensor in the drive assembly to measure an actuation load;

e. a sensor for measuring power output of the motor;

f. a console for remote control of the motor, said console comprising hand manipulated controls; and

g. a means for providing proportionate displacement feedback to a trigger from the sensors.

2. The surgical instrument of claim 1, wherein the motor is adjacent to the actuation shaft.

3. The surgical instrument of claim 1, wherein the motor is located substantially within the actuation shaft.

4. The surgical instrument of claim 3, wherein the consol comprises an electrically wired connection to the motor.
