Abstract

An endoscope power supplying appliance comprising an operation unit, a cylinder unit and an electrode that is used by inserting an endoscope, wherein the electrode is set at the distal end of the cylinder unit and the operation unit at the other end, an optical lens portion of the endoscope inserted into the power supplying appliance is capable of protruding beyond the end of the power supplying appliance, and the endoscope can move along an axial direction of the power supplying appliance. Further the endoscope power supplying appliance of this invention is effective for treatment such as coagulation of microvessels performed under endoscope and in particular blocking operation of sympathetic nerves in the chest region performed under endoscope, only one minimized skin incision allows the operation. Because it is not necessary to insert the appliance or pull it out of the body during the operation, frictional irritation to the incised portion is only caused at the time of insertion and extraction of the appliance before and after the operation, which minimizes the damage of the incised portion. Consequently the patient does not necessarily hospitalize for a long time and may leave hospital and go home on the day of operation.

Claims
