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.
An electrosurgical system including a generator for generating radio frequency (RF) 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,
An electrosurgical generator for generating radio frequency (RF) power, wherein the generator comprises a bipolar output having at least two output lines for coupling to bipolar electrodes of a bipolar electrosurgical instrument, and a monopolar output having at least one output line for a monopolar patient return electrode separate from the instrument, wherein the generator comprises at least one source of RF power and is adapted to operate in a first supply state in which an RF output waveform is delivered between the two output lines of the bipolar output, and a second supply state in which an RF output waveform is delivered between (a) at least one of the two output lines of the bipolar output and (b) the output line of the monopolar output, and wherein the generator further comprises a controller operable in at least one mode of the generator, to cause operation of the generator to alternate continuously between the first supply state and the second supply state for combined bipolar and monopolar RF energy delivery.
