High frequency surgical instrument, for cutting and/or coagulation of biological tissue, has two transistor switches operated independently for the oscillation circuit

摘要

The high frequency surgical instrument (1), for cutting and/or coagulation of biological tissue, has at least one oscillation circuit (11) and at least two switches (13,14) for the connection of the oscillation circuit to an electrical power supply (16).A control unit (15) is for at least one switch so that the switches can be operated independently of each other. The control modes allow the switches to be operated alternately or in parallel.
