る。As shown in FIG. 8A, a conventional endoscope forceps plug a of the above-mentioned construction is used by combining a first plug c and a second plug d which are integrally connected. In this state, after the treatment tool i is inserted into the treatment tool insertion channel of the endoscope through the forceps stopper a, the first stopper c to the second stopper d.
When the second plug portion d is removed as shown in FIG.
The treatment tool i remains inserted in the slit g.

置具の挿入が非常に重くなる問題がある。[0010] Here, the guide wire used when performing the above-described treatment tool replacement work needs to be about twice as long as the catheter, and thus the guide wire is detached from the first stopper c. It is difficult to pull out the guide wire from the inside of the slit g of the second plug portion d. Therefore, when performing a series of procedures for the above-described treatment tool replacement work using a guide wire, the second plug portion d cannot be removed from the first plug portion c. Therefore, even when a treatment tool having a small diameter is used first and then the treatment tool is switched to a treatment tool having a large outer diameter, the first stopper c and the second stopper d are used in a combined use state in which they are integrally connected. Since there is a need to insert a treatment tool having a large outer diameter into the forceps plug a, the insertion resistance of the treatment tool having a large outer diameter becomes large, and the insertion of the treatment tool becomes extremely heavy.
