Abstract
A diathermic hand-held instrument (1) and a detachable endoscopic probe (101) for use in surgical operations, particularly in laprascopic ultrasonic dissections during which surgery-related hemorrhaging must be stopped, e.g., by means of inert gas welding the blood vessels. The endoscopic probe (101) of the present invention provides for both coagulation and dissection in one tool. In particular, a sonotrode (8) that receives a gas supply line (19) and a suction line (6) is embodied to be electrically conductive. The endoscopic probe (101) also may be attached to alternative hand-held instruments.
