Abstract

A high-frequency surgical device encompassing control electronics that control a power unit which utilizes a high-frequency transformer that is the only galvanic separation between the supply voltage and the patient/user unit.

Claims

1. A high-frequency surgical device encompassing:

a power supply unit, which is provided with a high-frequency transformer for transforming a supply voltage to an output voltage;

control electronics for controlling the output of the power amplifier to the high-frequency transformer; and

a patient/use unit connected to the output of the high-frequency transformer, said high-frequency transformer being the sole galvanic separation between the supply voltage and the patient/use unit.

2. A device according to claim 1, wherein said control electronics are galvanically separated from said power unit.

3. A device according to claim 1 wherein said control electronics include an element galvanically separating it from the power unit and selected from the group consisting of opto-coupler, transmitters, utilized switches and keys.

4. A device according to claim 1 wherein said control electronics are provided with a separate supply circuit.
