Abstract
In a high-frequency surgical apparatus having a number of electrode-connections for a neutral electrode and a number of electrodes, respectively, for monopolar and bipolar operation, a single high-frequency generator operating through a transformer with monopolar and bipolar secondaries designed to work into different impedance loads is provided in combination with a multipole switch for switching over between bipolar and monopolar use. A warning signal is produced only if the switch is set for a monopolar use, even if the neutral electrode is not properly connected. The bipolar output may be used independently of whether a neutral electrode is connected to the apparatus or not. In this manner unintended injuries or damage by a contact with an electrode are avoided. Examples for the field of use of such electrosurgery units are Dermatology, Gynaecology, Ophthalmology, Dental Surgery, ENT and Cosmetic Surgery.
