Claim:
1. A surgical device, comprising: an end effector including first and second jaws configured to engage tissue between facing engagement surfaces thereof; a sensor configured to sense an impedance of the tissue engaged between the facing engagement surfaces; a cutting element configured to cut the tissue engaged between the facing engagement surfaces; a motor configured to provide an output that causes the cutting element to translate through the end effector at a speed; and a controller configured to change an output of the motor based at least in part on the sensed tissue impedance, thereby controlling the speed of the cutting element translating through the end effector, wherein when the cutting element is cutting the tissue, the controller is configured to control the output of the motor such that the output of the motor cannot exceed 80% of a total output capability of the motor; and after the cutting element has cut the tissue, the controller is configured to control the output of the motor such that the output of the motor is allowed to exceed 80% of the total output capability of the motor.
