Abstract: A medical device equipped for switching the device on and off carries out at least one safety-relevant function in the operating state, using at least one operating parameter with a set target value. In order to ensure a reliable function of the device and not disturb a medical treatment, the device performs a first self-diagnosis following switch-on and before reaching an operating state and performs a second self-diagnosis following switch-off and before terminating the operating state, during which self-diagnoses the same operating parameter of the device is checked in each case for deviation from the target value. The technology also relates to a corresponding method for operating a medical device.

Abstract: A bipolar electrosurgical tool (20) for a bipolar electrosurgical instrument (10) includes a first jaw part (30) with a first gripping face (31), a second jaw part (40) with a second gripping face (41) facing the first gripping face (31), a joint (50) that enables the second jaw part (40) to move pivotally in relation to the first jaw part (30), a first electrode (63) on the first jaw part (30) and a second electrode (64) on the first jaw part (30). The second electrode (64) is electrically insulated from the first electrode (63). There is no electrode arranged on the second jaw part (40).
