Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an endoscope holding apparatus configured to support an operation unit in a state where an insertion unit of an endoscope is suspended.
[0002]
[Prior art]
In general, this type of endoscope holding apparatus supports an operation unit in a state where an insertion portion flexible tube of an endoscope is suspended downward.
[0003]
Then, when the insertion portion flexible tube is long, one or a plurality of flexible tube engaging members are provided for engaging the intermediate portion of the insertion portion flexible tube in a looped state.
[0004]
[Problems to be solved by the invention]
However, the length, thickness, hardness, and ease of bending of the insertion tube of the endoscope vary widely depending on the model, and will be completely different if the model is different or a new model is released. .
[0005]
Therefore, depending on the model, the flexible tube engaging member may not fit well, and the loop of the insertion portion flexible tube becomes larger or smaller than necessary, so that the storage property and the durability of the flexible tube can be reduced. In some cases, problems may occur.
[0006]
Therefore, the present invention provides an endoscope holding device that can adapt the position of the flexible tube engaging member and hold the endoscope in a good state regardless of the type of endoscope. An object is to provide an apparatus.
[0007]
[Means for Solving the Problems]
In order to achieve the above object, an endoscope holding apparatus according to the present invention is an endoscope holding apparatus configured to support an operation unit in a state in which an insertion portion flexible tube of an endoscope is suspended downward. One or a plurality of flexible tube engaging members are provided for engaging the intermediate portion of the insertion portion flexible tube in a looped state, and at least one of the flexible tube engaging members is positioned It is characterized by being able to change and fix.
[0008]
The flexible tube engaging member may be a wheel-like member arranged so as to be movable along the slit.
An insertion portion distal end protection frame for loosely surrounding the vicinity of the distal end portion of the insertion portion may be provided, and the endoscope holding device may be attached to a movable cart.
[0009]
DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described with reference to the drawings.
FIG. 1 shows an endoscope cart 1 on which an endoscope 50 and a light source device and the like can be freely moved. Wheels 2 that can be rotated in different directions are provided at the four corners of the bottom thereof. It is attached.
[0010]
The operation unit hanger 3 for supporting the operation unit 51 of the endoscope 50 is attached to the upper end portion of the rod 4 that can be expanded and contracted in the vertical direction and is disposed above the upper end of the cart 1. By tightening the tightening screw 15, the height is fixed.
[0011]
The operation portion hanger 3 is formed with a groove for fitting the operation portion 51 of the endoscope. By inserting the operation portion 51 there, the insertion portion flexible tube 52 can be operated in a state of hanging downward. The part 51 can be supported.
[0012]
A hole through which the distal end portion 52a of the insertion portion 52 that hangs down from the operation portion 51 is formed in the insertion portion distal end protection frame 6 disposed almost directly below the operation portion hanger 3 in the vertical direction, and the insertion passed therethrough The tip portion 52a of the portion 52 is prevented from wobbling.
[0013]
A support plate 11 having a long slit 12 formed in the vertical direction is attached to the outer surface of the support column 10 on the side surface of the cart 1, and the intermediate portion of the insertion portion 52 is engaged in a looped state (hangs). ) Are attached so as to be movable along the slit 12 and are fixed to the support plate 11 by a manual fixing nut 14.
[0014]
2 and 3 are II-II and III-III cross-sectional views showing the structure of the portion, and the support plate 11 is fixed in a state where the portions other than both ends are lifted from the outer surface of the column 10. Then, the bolt 15 passed through the slit 12 from the back side of the support plate 11 is loosely inserted into the central shaft hole of the flexible tube engaging member 13, and the manual fixing nut 14 is screwed to the tip thereof. Reference numeral 16 denotes a rotation stop member formed along the back surface of the support plate 11 so as to stop the rotation of the bolt 15.
[0015]
Accordingly, if the manual fixing nut 14 is loosened, the flexible tube engaging member 13 together with the bolt 15 can be moved along the slit 12 to an arbitrary position, and if the manual fixing nut 14 is tightened, it is possible at that position. The flexible tube engaging member 13 can be fixed.
[0016]
The flexible tube engaging member 13 is formed in a wheel shape in which a flange 13a is formed to protrude on the outer side surface, and the insertion portion 52 of the endoscope 50 is placed along the rear portion of the flange 13a. As shown in FIG. 1, the intermediate portion of the insertion portion 52 can be engaged in a looped state.
[0017]
In the endoscope holding device configured as described above, in the case where the insertion portion 52 is a short model, the insertion portion 52 may be simply suspended from the operation portion 51 supported by the operation portion hanger 3. If is slightly longer, the rod 4 may be extended.
[0018]
However, in the case of a model in which the insertion portion 52 is very long, or in a usage environment where the rod 4 cannot be extended too much, the intermediate portion of the insertion portion 52 is looped and the flexible tube engaging member 13 is engaged. Will be combined.
[0019]
In that case, the position of the two flexible tube engaging members 13 can be freely set according to the length, thickness, hardness, ease of bending, and the like of the insertion portion 52. Therefore, the endoscope 50 can be held most compactly in a state where the insertion portion 52 is not forced.
[0020]
FIG. 4 shows an endoscope holding apparatus according to a second embodiment of the present invention, in which the flexible tube engaging member 13 attached to the support plate 11 is integrated, and the other configuration is as follows. This is the same as in the first embodiment.
[0021]
As described above, even when the number of the flexible tube engaging members 13 is one, by allowing the fixed position to be moved, the intermediate portion of the insertion portion 52 is looped to a state close to the optimum state, so that the flexible tube engaging member 13 is moved. Can be engaged.
[0022]
The present invention is not limited to the above embodiment, and one or a plurality of flexible tube engaging members 13 are provided, and the position of at least one flexible tube engaging member 13 is changed. The flexible tube engaging member 13 does not necessarily have to be straight in the vertical direction. Further, the endoscope holding device may not be attached to the movable cart.
[0023]
【The invention's effect】
According to the present invention, one or a plurality of flexible tube engaging members for engaging the intermediate portion of the insertion portion flexible tube in a looped state are provided, and at least one flexible tube engagement therein is provided. By enabling the member to be fixed by changing the position, any type of endoscope in which the length, thickness, hardness, ease of bending, etc. of the insertion portion flexible tube is different, The position of the flexible tube engaging member can be adjusted, and the endoscope can be held in a good state.
