SYSTEM AND METHOD FOR CONTROLLING ELECTROSURGICAL OUTPUT

摘要

An electrosurgical generator for supplying electrosurgical energy to tissue includes sensor circuitry configured to measure a voltage phase and a current phase through tissue and a processing device configured to compare the measured voltage and current phase to generate a real power component. The electrosurgical generator also includes a controller configured to regulate output of the electrosurgical generator based on the real power component and/or a predetermined imaginary impedance of tissue.
