<p>An electrosurgical system includes a generator (10) for generating radio frequency power, an electrosurgical instrument (12) including at least first and second bipolar electrodes (3A, 3B) carried on the instrument, and a monopolar patient return electrode (11) separate from the instrument. The generator comprises a source (1) 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 (3A, 3B) 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 (11). A controller is operable to control the generator (10) 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.</p> |
