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, two high-frequency generators are connected to a single voltage source, so that the second generator may serve exclusively for supplying a high-frequency current to the electrode-connections for bipolar electrodes. A warning signal is produced only if a switch is closed for a monopolar use, even if the neutral electrode is not properly connected. Therefore the bipolar high-frequency generator may be actuated independently of whether a natural electrode is connected to the apparatus or not. In this manner unintended injuries or damages by a contact with an electrode are avoided. In an alternate embodiment of the invention only a single high-frequency generator is provided in combination with a switch-over device for switching over between bipolar and monopolar use, so that in the case of bipolar use the protective circuit is disabled. Examples for the field of use of such electrosurgery units are Dermatology, Gynaecology, Opthalmology, Dental Surgery, ENT and Cosmetic Surgery.
