Abstract
An ultrasonic surgical system includes an ultrasonic generator configured to output a drive signal, an ultrasonic transducer configured to receive the drive signal and output mechanical motion, a waveguide configured to transmit the mechanical motion to a blade disposed at a distal end portion thereof, a sensor, and a controller. The blade is configured to oscillate in response to receipt of the mechanical motion and defines a displacement when oscillating. The sensor is configured to sense a property indicative of tension on tissue and the controller is configured to adjust the drive signal to thereby adjust the displacement based upon the sensed property. A method of treating tissue includes applying a drive signal to an ultrasonic transducer to oscillate an ultrasonic blade, sensing a property indicative of a tension on the tissue, and adjusting the drive signal based upon the sensed property to thereby adjust the displacement of the blade.
