[0005]

By the way, the endoscope is
From the relationship that the insertion part is directly inserted into the body cavity of the patient,
After use, the insertion part is soiled due to the attachment of dirt. When the cart is moved by suspending the dirty insertion section after use, the insertion section may shake due to the vibration of the cart and may come into contact with the cart or other objects, which is not preferable from the viewpoint of hygiene. In addition, the endoscope needs to be cleaned each time it is used, but since the cleaning device is not usually installed in the examination room, it is once mounted on the cart and transported to the position where the cleaning device is installed. It is necessary to take it out of this cart and set it in the cleaning device.
Therefore, it is necessary to touch the dirty insertion portion at least twice, when mounting on a cart and when transferring to a cleaning device, which is uncomfortable for a person who performs the work, and this work is also performed. Therefore, the work itself is troublesome, for example, gloves must be worn, and it is not preferable in terms of hygiene.

The present invention has been made in view of the above points, and an object of the present invention is to mount an endoscope so that the insertion portion can be fixed without directly touching the insertion portion, An object of the present invention is to provide an endoscope holder device that can be held in a cart and that can be washed as it is.

[0007]

In order to achieve the above-mentioned object, the present invention provides an operating portion for detachably holding an operating portion of an endoscope main body on one side surface of a holder main body that can be immersed in a cleaning device. Between the holder, the distal end locking portion that detachably locks the distal end portion of the insertion portion extended from the main body operation portion, and the distal end portion of the insertion portion and the continuous portion to the main body operation portion, , An insertion part fixing mechanism including a holding part that holds at least one place and an insertion part routing path that draws the entire insertion part in a predetermined direction, and can be attached to and detached from a cart in which a light source device of an endoscope is installed. It is characterized in that a connecting member to be connected to is attached.

[0008]

With the connecting member of the holder connected to the cart, the operation portion holder provided on the holder body holds the operation portion of the main body, and the insertion portion is fixedly held by the insertion portion fixing mechanism. Further, if necessary, the light guide flexible portion and its connector portion are also fixed. Here, since the insertion portion is a long member, it is also a flexible member at the same time,
In the holder body, it is arranged to be routed as compactly as possible along the route for guiding the insertion portion, and by being held by the holding portion, the whole is fixed so as not to move. After the use of the endoscope, the insertion portion is soiled due to the adherence of body fluid. Therefore, when fixing the insertion portion, it is not preferable in terms of hygiene that a person who performs the work directly touches the insertion portion. Therefore, first, the tip of the insertion section is locked to the tip locking section, and in this state, the tip section of the insertion section is moved along the insertion section routing path,
The intermediate part is held by the holding part so as not to move unintentionally, and the tip part of the insertion part is guided to a predetermined position.
Thus, this insertion section routing path is looped, spiraled,
By forming the meandering shape or the like, the insertion portion, which is a long member, can be drawn around in a compact manner.

As described above, by mounting the holder holding the insertion portion in a substantially fixed state on the cart, the insertion portion does not move unintentionally when the cart is moved. As a result, there is no risk that the soiled insertion portion will come into contact with other members or the like. Then, by separating the holder on which the endoscope is mounted from the cart and immersing the endoscope together with the holder in, for example, a cleaning tank that constitutes a cleaning device, the endoscope is directly transferred without being transferred. Can be washed in the state of. Thus, by providing the locking device or the like at an appropriate position, the flexible insertion portion and the light guide flexible portion can be freely routed, and the holder main body becomes small and compact. Therefore, the entire endoscope can be sufficiently cleaned even with a small cleaning device. Then, after cleaning, the holder may be connected to the cart again.
