FEEDBACK ALGORITHMS FOR MANUAL BAILOUT SYSTEMS FOR SURGICAL INSTRUMENTS

Abstract: a surgical system includes a firing rod configured to be translated to deploy surgical staples during a firing stroke and a microcontroller configured to adjust firing rod velocity by pausing movement of the firing rod for a predefined period of time when the microcontroller detects a current draw by a motor driving the firing rod that exceeds a predefined threshold value. after the pause, the firing stroke can be resumed and if the current draw increase is less than the threshold value, the microcontroller can proceed cause the motor to drive the firing rod through the firing stroke without adjusting the velocity of the firing element.
