Abstract
A control system for an ultrasonic surgical device has a console operatively connected to a power source and configured for detachable connection to the ultrasonic surgical device. A control circuit of the console is configured to regulate an operating signal to correspond to the operating characteristics of the ultrasonic surgical handpiece in response to a loading signal. An operator input of the console operatively connects to the control circuit to provide a control signal.

A method for operating an ultrasonic surgical device using a console comprising:
- generating a generating signal at a drive frequency with a control circuit of the console, wherein the generating signal is based on an operator input;
- generating a drive signal having a drive voltage and a drive current with the control circuit in response to the generating signal;
- comparing the drive voltage and the drive current with a phase comparator of the control circuit;
- generating a phase adjustment with the phase comparator based on a comparison the drive voltage and of the drive current;
- generating an operating signal in response to the phase adjustment to operate the ultrasonic surgical device.
