Abstract
An ultrasonic electromechanical system for an ultrasonic surgical instrument may include an ultrasonic blade, a clamp arm disposed opposite the ultrasonic blade, an ultrasonic transducer configured to oscillate the ultrasonic blade in response to a drive signal, and a control circuit coupled to the ultrasonic transducer. The control circuit can be configured to determine a temperature of the ultrasonic blade, increase an amount of power of the drive signal when the temperature of the ultrasonic blade is less than a first predetermined value, and decrease the amount of power of the drive signal when the temperature of the ultrasonic blade is greater than a second predetermined value. The second predetermined value may be greater than the first predetermined value. An ultrasonic generator connectable to the ultrasonic electromechanical system may include the control circuit.
