ABSTRACT:
A resectoscope includes an electrode which is effective to resect an affected part by cauterization upon energization with high frequency current. A slider element is slidable lengthwise of the resectoscope and includes an electrode receiving hole in which an electrical terminal is mounted. The proximal end of the electrode is inserted into the hole and secured to the terminal. Thus the electrode is fixed to the slider and can be moved back and forth with respect to the resectoscope's body. An elastic seal member having an internal diameter less than the external diameter of an insulation coat on the electrode is located in the opening into the hole to prevent water droplets or blood from entering into the hole.
