Claim:
1. An electrosurgical system comprising: a generator for generating radio frequency power, an electrosurgical instrument, and a switch and a switching circuit, the generator comprising: the electrosurgical instrument comprising: the switching circuit being operable in response to the switch to vary connections between the radio frequency output lines and the first and second tissue treatment electrodes, such that, in a first configuration, the first tissue treatment electrode is placed in circuit with the first return electrode so as to treat tissue adjacent to the first electrode pair that is disposed longitudinally of the shaft, and, in a second configuration, the second tissue treatment electrode is placed in circuit with the second return electrode so as to separately treat tissue adjacent to the second electrode pair that is disposed laterally of the shaft, at least the first tissue treatment electrode being capable of the vaporisation of tissue.
