Abstract
An electrosurgical device for coagulating and/or cutting biological tissue that includes an instrument for application of high-frequency current, an activation switch, a high-frequency generator, and a safety unit. The instrument for application of the high-frequency current includes first and second branches having respective first and second jaw parts that are connected such that they are movable relative to one another. The safety unit interrupts the current supply to electrodes of the instrument when the jaw parts assume a position relative to one another that is not suitable for coagulation by means of the high-frequency current, e.g. when the jaw parts are open. Thus, erroneous operation of the device may be prevented.
