2. Description of the Related Art Conventionally, by inserting an elongated insertion portion into a body cavity, an organ or the like in the body cavity can be observed, and if necessary, a treatment device (also referred to as a treatment tool) inserted into a treatment channel. Medical endoscopes capable of performing various types of treatments using a medical device are widely used.

[0003] The treatment instrument has a treatment instrument channel of an endoscope whose diameter is small (about 3 mm) and long (2 m).
It has a slender structure so that it can be inserted into the lumen. For this reason, when inserting this slender treatment instrument into the treatment channel of the endoscope, there is a possibility that the treatment instrument may be broken or damaged. Had to pay close attention to it.

For example, Japanese Unexamined Patent Publication (Kokai) No. 64-80335 discloses that in order to prevent damage during insertion of the treatment instrument, a member having appropriate elasticity is used for treatment equipment or the tip shape is made smooth. This shows an endoscope that improves the insertability.

[0005] Further, when performing a treatment endoscopically, since the endoscope and the treatment tool are independent, a medical technician can use both hands to operate a complicated endoscope and operate the treatment tool. And
Since several persons, including an attendant, must operate the endoscope and the treatment tool, skilled operation techniques are required.

However, as disclosed in JP-A-64-80335, improving the material and making the shape curved does not solve the fundamental problem. When a material is used, there are problems in that it is difficult to obtain the material, the manufacturing method is complicated, and it is not suitable for mass production, and the treatment tool becomes expensive.

In order to facilitate the operation between the endoscope and the treatment tool, in the case where the endoscope and the treatment tool are connected and fixed, the operation section of the endoscope interferes with the operation section of the treatment tool. Therefore, there was a problem that operability deteriorated.

Further, when performing post-processing such as cleaning and disinfection of slender treatment equipment, the treatment tool has a problem that it is difficult to wash and takes a long time for post-processing, and the treatment tool is stored after the post-processing. However, when performing management, there is a problem that the storage space becomes large because the treatment tool is elongated.

The present invention has been made in view of the above circumstances, prevents damage to a treatment instrument, is easy to operate under an endoscope, can be used for a plurality of endoscopes, and can be stored in a small space. It is intended to provide a possible endoscope system.
