摘要： An electrosurgical generator apparatus controls a variable output signal to electrodes. The generator apparatus operates in a cut mode, a coagulation mode or a stimulate mode. The generator apparatus comprises a DC power supply that provides regulated low voltage and high voltage outputs and a radio frequency (RF) waveform generator circuit that provides pulse duration modulation (PDM) of a carrier signal. The carrier signal directly affects the variable output signal to the electrodes. A control circuit controls a variable output signal to electrodes used in electrosurgical procedures. The control circuit comprises a DC power supply circuit that provides regulated low voltage and high voltage outputs and an RF waveform generator circuit that provides pulse duration modulation of a carrier signal. The carrier signal directly affects the variable output signal to the electrodes.

摘要： An electrosurgical bipolar RF generator apparatus includes a bipolar electrode. An aperiodic sequence of uniform width bursts of a high frequency signal are electronically synthesized. Substantially identical decaying amplitude envelopes are impressed on the bursts of the high frequency signal. Each of the envelopes has a predetermined rate of change from a preselected initial amplitude. The impressed bursts of the high frequency signal are applied to the electrode. The electrical apparatus operates in a cut mode or a coagulation mode. The apparatus includes a power supply for providing a variable DC voltage, a short circuit detect circuit for detecting a short circuit at the bipolar electrode, and an open circuit detector for detecting an open circuit at the bipolar electrode.
