The apparatus main body 3 is provided with a handle grip 4 projecting downward. Inside the insertion pipe 2, there is provided an insertion portion fixing plate 5 placed parallel to the long axis direction. The insertion part fixing plate 5 is installed in the insertion pipe 2,
It is movable in a direction intersecting with the long axis direction of the insertion pipe 2, in this case, in a direction orthogonal thereto. An elastic body 6 formed of an elastic member such as a spring or rubber, which is provided inside the grip portion 4, is in contact with the back surface (lower surface) of the insertion portion fixing plate 5. The elastic body 6 constitutes an urging means for pressing the insertion portion fixing plate 5 against the insertion portion of the endoscope inserted through the insertion channel 2. Then, the insertion portion of the endoscope inserted into the insertion channel 2 is sandwiched between the inner surface of the insertion channel 2 and the insertion portion fixing plate 5 by urging the insertion portion fixing plate 5 to insert the endoscope. The device body 3 is fixedly held by the unit.

The insertion portion fixing plate 5 is operable by an operating body 7 provided on the apparatus main body 3 in a direction of retreating from the insertion tube 2. In other words, an operating means for retracting the insertion portion fixing plate 5 to a position which does not hinder the insertion of the insertion portion of the endoscope to be inserted into the insertion channel 2 is configured. As shown in FIG. 2 and FIG. 3, the operating body 7 is disposed at a position that can be operated by a finger of the hand that grips the gripping portion 4, avoiding the gripping portion 4.

Thus, even if the so-called endoscope has a viewing direction parallel to the long axis of the endoscope, that is, a so-called zero-degree viewing direction, the endoscope holding device 1 can be used to make the endoscope long axis. Observation is possible even for an object having an angle with respect to the object.

Further, since the mirror portion 70 is rotatable with respect to the endoscope and is movable at an angle with respect to the long axis direction, observation in all directions centering on the distal end side of the endoscope becomes possible. Thus, there is an effect that it is possible to use a versatile endoscope with one endoscope.

For example, in the otolaryngology, a nasal scope is used for observing the inside of the nose, and when observing the pharynx and the oral region,
Each uses a dedicated posterior nasal endoscope or pharyngeal endoscope. The posterior nasal endoscope was seen from the upper side in the longitudinal direction of the endoscope, and the pharyngeal endoscope was obliquely viewed downward from the longitudinal axis. In such a situation, if the nasal endoscope in the direct viewing direction and the endoscope holding device 1 of the present embodiment are adopted, a single nasal endoscope in the direct viewing direction can be used as a retronasal endoscope or a pharyngeal endoscope. It can be used. Further, in the endoscope holding device 1 of the present embodiment, since the raising light 67 is provided with the illumination light supply means, it is not necessary to connect a cable such as a light guide cable to the endoscope. There is no worry about deterioration.
