  • Electrosurgical apparatus
    Patent number: 6890331
    Abstract: An electrosurgical apparatus comprises a high frequency generator (1) with an associated power control system, a handpiece (2) with means for removably mounting an electrode (5) therein, and a connection cable (3) between an output (4) of the generator and the handpiece. The transfer characteristic of the system provides a substantially true ohmic transfer of loads on the electrode side of the connection cable (3) to the generator side thereof at or around a predetermined load on the electrode. In order to achieve a fully automatic and optimalized control af power supplied from a cutting electrode, whereby the control is instantly responding, to changes in the electrode load, the electrosurgical apparatus is characterized in that the power control system comprises a driver stage (7) followed by a reflectormeter (9) adapted and arranged to sense the generator output (4).
