Abstract
An electrosurgical system includes a generator for generating radio frequency power, an electrosurgical instrument including at least first and second bipolar electrodes carried on the instrument, and a monopolar patient return electrode separate from the instrument. The generator comprises a source of radio frequency (RF) power, and has a first supply state in which the RF waveform is supplied between the first and second bipolar electrodes of the electrosurgical instrument, and a second supply state in which the RF waveform is supplied between at least one of the first and second bipolar electrodes and the monopolar patient return electrode. A controller is operable to control the generator such that, in at least one mode of the generator, a feeding means is adapted to alternate between the first and second supply states to supply an alternating signal.
