[Problems to be solved by the invention]
However, the invention described in Japanese Examined Patent Publication No. 6-9577 in the above-mentioned conventional example is not only heavy but difficult to perform a therapeutic operation because a flexible multi-joint hose is configured to be shared. Since it is necessary to share the joint part shape of various treatment instruments connected to the sexual multi-joint hose, there is a problem that the joint part shape becomes large.
[0009]
In the invention described in Japanese Patent Laid-Open No. 2001-178753, the multi-joint joint portion integrally handles the joint portion that realizes the multi-joint and the multi-joint hose, and is detachably attached to the multi-joint hose itself. Since it is necessary to provide various electrical wiring and air and water pipes so that they can be used in common with each treatment device, the problem is that the multi-joint hose is thick and heavy, making it difficult to perform treatment. is there.

Furthermore, since the hose becomes unusable after about 250 sterilization treatments, a new one needs to be replaced. For this reason, it is desirable to make the multi-joint hose disposable by sterilization, but in order to make it disposable, the hose must be inexpensive. In this respect, the multi-joint hose used in the conventional treatment instrument is expensive because it has a built-in means for automatically recognizing the type of the treatment instrument, and there is a problem that it is difficult to make it disposable.
