位へ導入されることが多い。[Background Art] In recent years, catheters have been widely used as a type of medical treatment tool to be inserted into body cavities to inject drugs or to suction and collect body fluids. This type of catheter can be inserted into a body cavity alone as shown in Japanese Patent Application Laid-Open No. 1-113073, or can be inserted into a guide tube such as an endoscope channel or a guide tube to guide the body cavity. It is often introduced into the target area.

がおいている。On the other hand, the proximal end of these guide tubes, which are not inserted into the body, is used to introduce CO2 gas into the body cavity through the guide tube, for example, as shown in Figure 4, or to leak body fluids or perfusion liquids to the outside. In order to prevent this, a backflow prevention valve called a forceps plug is provided. This forceps plug is made of an elastic material such as rubber, and has a slit in its center for liquid-tightly and air-tightly inserting the catheter to be inserted, and an ultra-thin diameter smaller than the outer diameter of the catheter to be inserted. There are holes etc.

。そのため、操作が頻雑であるばかりでなく、押し込み
操作中にカテーテルを座屈させるという問題がある。[Problems to be Solved by the Invention] When inserting a catheter into a guiding tube having a forceps plug as described above, it is necessary to guide the catheter while resisting frictional resistance such as the slit or round hole of the forceps plug. It is necessary to keep pushing the catheter into the tube, and by the time the tip of the catheter protrudes beyond the tip of the guiding tube and reaches the target site in the body cavity,
It is necessary to repeat the catheter pushing operation many times. Therefore, there is a problem that the operation is not only frequent, but also that the catheter may buckle during the pushing operation.
本発明は上記課題に着目してなされたものであり、その
目的は、体腔内に挿入される誘導案内管内に気密および
液密に配置されるカテーテル等の医療用処置具において
