摘要： A control system for use with an electrosurgical generator which delivers electrosurgical energy to tissue has a control module. The module includes a processor executing an algorithm. The algorithm has the steps of determining a sensed voltage value corresponding to a sensed voltage signal output by the electrosurgical generator and determining a sensed current value corresponding to a sensed current signal output by the electrosurgical generator. The algorithm has the steps of determining phase information corresponding to a phase shift between the voltage signal and the current signal and determining a characteristic related to the electrosurgical energy delivered to the tissue using the phase information, the sensed voltage value and the sensed current value.

摘要： A closed-loop control system has a user interface for allowing a user to select at least one pre-surgical parameter. The system also has a sensor module for continually sensing at least one of electrical and physical properties proximate a surgical site and generating at least one signal and a control module for continually receiving the selected parameter from the user interface and the at least one signal from the sensor module. The system processes the signal in accordance with the parameter using at least one of a microprocessor, computer algorithm and a mapping. The control module generates a corresponding control signal relating to the signal from the sensor module, and provides the control signal to the generator. The control module has number of loop control modules with a first loop control module providing a ratio of a real time parameter value to a desired parameter value. The real time parameter value is from the signal from the sensor module. The first loop control module modulates another loop control module based in part on the ratio for controlling the generator
