METHOD OF EMERGENCY RETRACTION FOR ELECTROMECHANICAL SURGICAL DEVICES AND SYSTEMS

摘要

PROBLEM TO BE SOLVED: To provide electromechanical robotic and/or hand-held powered surgical devices and/or systems including an emergency retraction algorithm.SOLUTION: A surgical instrument 100 has a controller, and an end effector 300 selectively and removably connectable to the surgical instrument. The controller enters an emergency retraction mode when at least one input element of a surgical system 10 is incapable of providing control signals to the controller to operate a motor. The emergency retraction mode activates the motor to withdraw a drive assembly from any advanced position thereof.
