ABSTRACT:
An apparatus of a new type of resectoscope for prostatectomy essentially comprising an electrical driving system which is connected to a replaceable high resistivity electrotome, or a screw thread cutting-knife, and a tube-electrode to achieve the spinning-type of resection for prostate or bladder tumor. A DC-motor and a transmission-gear set are mounted within a hand grip. Other devices, such as the resectoscope sheath, telescope universal electro-surgical unit, optical light source, and universal light guide cable may be connected to this apparatus. The resectoscope provides a high speed operation, safety, effectiveness, and convenience.
