Generally, a resectoscope is constructed by inserting an optical viewing tube and an electrode rod into a sheath. The electrode rod is connected to an operating slider provided on the hand side, and can be moved back and forth in the front-back direction by moving the operating slider. By the way, as a means of fixing this electrode rod to the operating slider, there is a method of first inserting the proximal end of the electrode rod into the mounting hole of the slider, and then tightening and fixing the proximal end with a screw. Application No. 166059 (1982)
No. 70211)).

付け孔から抜けなくなる不具合が起る。 However, with this method, the electrode cannot be attached with a single touch, making the operation of attaching the electrode during surgery complicated. In addition, it is easy to tighten the screw too strongly by mistake, and in this case, the electrode rod is crushed and cannot be removed from the mounting hole.

単には着脱できない。 On the other hand, there is a separate application for Utility Model Application No. 57-3506 (Utility Model Application No. 58-108814). This is provided with a member that holds the base end of the electrode rod, and this member is tightened with a screw to hold the base end. Therefore, the problem of the electrode rod being crushed is certainly solved to some extent, but since the electrode rod is attached and removed by operating a screw, it cannot be easily attached and detached.

なつている。 On the other hand, an insertion hole 2 is provided in the side wall of the guide member 28.
An insertion hole 38 communicating with the electrode rod 6 is formed, and the metal part 25 of the electrode rod 3 is inserted into the guide hole 29 through this insertion hole 38.
Further, a locking hole 41 passing through the metal part 25 is formed in the insertion part 36 of the electrode fixing member 31. This locking hole 41 is formed in a size that allows the electrode fixing member 31 to be moved while the metal part 25 is inserted therethrough. The lower edge of this locking hole 41 (the side edge corresponding to the locking depression 27)
A locking portion 42 that falls into and locks the locking depression portion 27 is provided protrudingly on the. Further, as shown in FIG. 4, an inclined surface 43 is formed on the wall portion of the locking portion 42 on the insertion receiving side of the hardware portion 25. As shown in FIG. When the electrode rod 3 is inserted into the insertion hole 26, the tip of the metal part 25 hits this inclined surface 43.
By pushing in the electrode rod 3 as it is, the electrode fixing member 31 is pulled in against the biasing force of the coil spring 35 by its cam action. When the tip of the hardware part 25 climbs over the inclined surface 43, the coil spring 35 exerts a biasing force on the electrode fixing member 31, so that the locking part 42 moves over the locking depression part 27. automatically falls and locks. Further, if the operation button 34 is pressed and the electrode fixing member 31 is pushed in, the locking part 42 is retracted from the locking depression part 27, and if the electrode rod 3 is pulled in this state, it can be pulled out from the insertion hole 26. It's becoming like that.
