Abstract

See full text

A surgical stapling instrument comprising a handle, an elongate shaft, an end effector, a motor couplable with a supply of current, a firing member operably responsive to the motor, a current sensor, and a control circuit is disclosed. The firing member is movable from a proximal position to a distal position during a firing stroke. The control circuit comprises a processor and a memory configured to store instructions which, when executed from the memory cause the processor to activate the motor in response to an actuation input, receive an input from the current sensor regarding the current draw of the motor, deactivate the motor when the current draw of the motor exceeds a threshold current when the firing member is within a threshold distance relative to the proximal position, and retract the firing member to the proximal position.
