Abstract

An electrosurgical system includes at least a first unit and a second unit, the second unit being detachably connectible to the first unit and including an electrode assembly. The first unit includes a power supply, an RF oscillator circuit for generating a radio frequency output, and an output stage adapted to supply an RE output to the electrode assembly. The second unit includes an identification circuit presenting, in an alternating manner, a parameter with a first finite non-zero value for a first time period, and a parameter with a second finite value for a second time period. The first unit includes a sensing circuit and a controller adapted to detect a characteristic of the identification circuit and provide an output signal, the controller connected to the sensing circuit and receiving the output signal, adjusts the RF output so as to suit the particular electrode assembly.

First claim

The invention claimed is:

1. An electrosurgical system comprising:
a first unit including:
a) a power supply;
b) an RF oscillator circuit for generating a radio frequency output; and
c) an output stage adapted to supply an RF output to an electrode assembly; and

a second unit detachably connectible to the first unit and being associated with the electrode assembly, the second unit including an identification circuit configured to present to the first unit whilst the secon…
