Abstract
A surgical tool includes a drive housing, a closure tube extending from the drive housing, and an end effector arranged at an end of the closure tube and having opposing jaws. A method of operating the surgical tool includes operating one or more motors in a first direction at a constant velocity and thereby urging the closure tube to move and actuate the opposing jaws to engage and clamp onto tissue, stopping operation of the motor(s) in the first direction when a torque on the motor(s) exceeds a predetermined torque, storing an angular position of the motor(s) when the torque exceeds the predetermined torque, operating the motor(s) in a second direction opposite the first direction over a preset angular magnitude, and upon reaching the preset angular magnitude, operating the motor(s) in the first direction at the constant velocity.
