Abstract
The resectoscope apparatus comprises an elongate hollow sheath to be inserted into a body cavity, an electrode inserted through the sheath to make such treatments as of resecting and coagulating tissues within the body cavity by using a high frequency current, an operating part which can operate the electrode from outside the body, a cord for feeding a high frequency current to the electrode from a high frequency current source and an optical sighting tube inserted through the sheath and having an optical system which can observe the body cavity interior and the electrode is made integral at least on the rear end side with the cord. For example, the electrode has a shaft part connected at the rear end to the above mentioned operating part and inserted through the sheath and a tip electrode part provided at the tip of the shaft part and projected and retracted from the sheath tip. The operating part has a connecting part removably connectable to the sheath at the rear end and a slider connected with the electrode shaft part at the rear end and slidable in the axial direction. The resectoscope apparatus further comprises, for example, a connecting apparatus mechanically and removably…
