An electrosurgical system includes an electrosurgical generator (1) with a
plurality of output connections (2, 3, 4), only one of the output
connections at any one time being active in that it is able to receive
radio frequency power. A plurality of electrosurgical assemblies, each
including an electrosurgical instrument (5, 6, 7) and a cable (8, 9, 10)
are connected to the generator (1) via the output connections. The
electrosurgical assemblies each include indication means such as lamps
(17, 18, 19), illuminating when that particular electrosurgical assembly
is connected to the active output connection. A switch means, such as a
footswitch (11) or handswitches (24, 27) on the instruments, send a
signal to the generator to cause an RF waveform to be provided at the
active output connection.
