<P>PROBLEM TO BE SOLVED: To provide an electrosurgical generator which automatically switches between a plurality of operation modes corresponding to sensed feed back signals. <P>SOLUTION: The electrosurgical generator includes a closed loop control system having a sensor system configured to sense at least one of tissue properties and energy properties at a tissue site and to generate a sensor signal representative of the tissue properties and the energy properties. The control system includes a controller configured to select an electrosurgical operational mode from a plurality of electrosurgical operational modes in response to the sensor signal. A radio frequency arbitrary source is also included which is configured to generate a radio frequency input signal corresponding to the selected electrosurgical operational mode and a radio frequency output stage configured to generate a treatment signal which corresponds to the electrosurgical operational mode. The system also includes a predictive signal processor configured to adjust the radio frequency output stage in response to the radio frequency input signal, such that the radio frequency output stage alters the treatment signal in real time based on the selected electrosurgical operational mode. <P>COPYRIGHT: (C)2010,JPO&INPIT |
