Abstract

PURPOSE:To reduce a feeling of fatigue to a large extent by reducing the wt. load on an examiner and to keep operability well, by providing a movable body to the guide track mounted to a wall or ceiling and providing a hanging means, which can control the hanging height of an endoscope, to said movable body. CONSTITUTION:For example, a fixing jig 2 is fixed to the side wall of an examination room and the base end of a linear guide track 3 is pivotally supported by said jig so as to be revolvable around a vertical axis. A moving body running and moving along guide grooves 4a, 4b are mounted to the guide track 3 and a hanger 16 for holding the operation part 15 of an endoscope 14 in a suspended state through an engaging metal fitting 13 is connected to the under surface of the moving body 5 and a control mechanism 25 for controlling the hanging height of the endoscope 14 is incorporated in the hanger 16. For example, when the spring force F2 of a spring 26 is controlled, the endoscope 14 can be hung and held at a desired height position regardless of the magnitude of the wt. W of the endoscope 14.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an endoscope suspension holding device used during endoscopy.

[Conventional technology]

Conventionally, in endoscopy, the practitioner who operates the endoscope holds the operating section connected to the insertion section with one hand, and uses the other hand to hold the angle knob, air/water supply button, etc. on the operating section. During the examination, the operator was required to support the operating section with one hand at all times because the operator was operating various treatment tools inserted into the forceps opening of the operating section.

[Problem to be solved by the invention]

However, because the operating section of an endoscope has various mechanisms built into it, such as an angle mechanism that changes the direction of the tip of the insertion tube in conjunction with the angle knob, the operating section itself is relatively heavy and large. The longer the endoscopy takes, the more
There is a problem in that the practitioner feels more fatigued.

Therefore, the purpose of the present invention is to provide an endoscope hanging and holding device that can lighten the load on the operator during endoscopy, reduce fatigue, and has excellent operability. shall be.

[Means to solve the problem]

Therefore, in the present invention, a movable body that can move along the inner track is provided on a guide track attached to a wall or ceiling, and the operating section of the endoscope is removably suspended from this movable body. According to this configuration, the operating section of the endoscope is suspended from the wall or the wall by the hanging means. The endoscope is suspended from the ceiling, and this hanging means supports the entire weight of the endoscope, so the operator who operates the endoscope does not need to support the operation part during endoscopy, unlike in the past. The burden on the practitioner is reduced.

Moreover, the movable body with the operating section suspended can move along the guide track, and the hanging height of the operating section can be adjusted, allowing the practitioner to use the endoscope as freely as before. Not only can the endoscope be operated easily, but it can also be easily set in a position where it is easy to operate, and the operability of the endoscope can be maintained well.

〔Example〕

A first embodiment of the present invention will be described below with reference to FIGS. 1 to 4.

A fixture 2 is fixed to the side wall of the examination room indicated by reference numeral 1 in FIG. supported. As shown in Fig. 2, the guide track 3 has guide grooves 4 on both sides thereof.
a, 4b, and these guide grooves 4a, 4b are formed over the entire length of the guide track 3.

Note that a hanging wire 21 is provided at the lower end opening of the case 17.
A damper 33 that comes into contact with a stopper 32 fixed to the lead-out end of the suspension wire 21 to restrict the maximum winding position of the hanging wire 21.
is provided.

Furthermore, an adjustment mechanism 25 for adjusting the hanging height of the endoscope 14 is incorporated in the hanging tool 1B.

This adjustment mechanism 25 will be explained with reference to FIGS. 3 and 4. A mainspring 2B that urges the rotating drum 20 in the clockwise direction is housed in the case 17 of the hanging tool IB. The mainspring 2B has one end 28a locked to the rotating shaft 19, and the other end 28b locked to the outer periphery of the rotating drum 20.
1 is pulled out from the case 17 and the rotating drum 20 is rotated counterclockwise, the rotating drum 20 is rotated together with the rotating drum 20 in the tightening direction.

Further, an adjustment knob 27 that rotates integrally with the rotating shaft 19 is fixed to one end of the rotating shaft 19 protruding from the case 17, and on the outer periphery of one end of the rotating shaft 19,
A torsion coil spring 28 is attached to prevent rotation of the rotating shaft 19 to the case 17.

The torsion coil spring 28 has a coil portion 29 that tightens the rotating shaft 19, and a pair of leg portions 30a and 30b that extend from the coil portion 29 in opposite directions along a tangential direction. One leg 30a is fixed to the case 17, and the other leg 30b is fixed to the adjustment knob 27.
A release lever 31 is guided out in the radial direction to release the tightening of the rotation shaft 19. When the release lever 31 is pushed up to loosen the coil portion 29, the rotation shaft 19 is removed from the case 17. is now unfixed.

In such a configuration, a procedure for suspending and holding the operating section 15 of the endoscope 14 at a desired height position will be described.

Once the movable body 5 has been moved along the guide track 3 to a predetermined position, the hanging lobe 21 is pulled to the desired position, and the operating section 15 of the endoscope 14 is pulled to the hanger lobe 23 at the lower end. Multiply. Then, since the hanging lobe 21 is let out, the rotating drum 20 rotates counterclockwise, and the mainspring 26 is wound up. In this case, the tensile force of the hanging lobe 21 is Fl, and the load of the endoscope 14 is W.
If so, the mainspring 26 will be wound up with the force of F1+W, and this mainspring 2B will be connected to the hanging lobe 2.
If the opposite spring force F2 trying to wind up the endoscope 14 and the load W of the endoscope 14 are well balanced, the endoscope 14 will be suspended and held at a desired position.

However, if the load W of the endoscope 14 is larger than the spring force F2 of the mainspring 26, or conversely smaller, it becomes difficult to maintain the hanging position of the endoscope 14.
In this case, the adjustment knob 27 is operated to increase or decrease the spring force F2 of the mainspring 26.

That is, in the case of W>F2, first, release lever 31
is pushed up to release the fastening of the rotating shaft 19 by the coil portion 29. Then, the adjustment knob 27 is rotated clockwise to wrap one end of the mainspring 2B around the outer periphery of the rotating shaft 19, and the spring force F2 of the mainspring 26 is increased so that the relationship W-F2 is established.

On the other hand, in the case of W<F2, the rotation shaft 19 is unfastened in the same manner as above, and then the adjustment knob 27 is rotated counterclockwise to rewind the mainspring 2B and the W-F2 The spring force F2 of the mainspring 2B is decreased so that the relationship holds true.

Therefore, the mainspring 26'vJ spring force F2
By adjusting , regardless of the magnitude of the load W on the endoscope 14,
This endoscope 14 can be suspended and held at a desired height position.

According to the first embodiment of the present invention, the operating section 15 of the endoscope 14 is suspended from the side wall 1 of the examination room by the hanging tool 1B, and this hanging tool 16 is attached to the operating section 15. Since the entire weight is supported, the operator is freed from the burden of the operating section 15 during endoscopy. As a result, the burden on the practitioner is reduced, which allows the practitioner to concentrate on operating the operating section 15, and also significantly reduces fatigue.

In addition, the moving body 15 with the operating section 15 suspended thereon can move freely along the guide track 3, and the hanging height of the operating section 15 can also be freely adjusted. The mirror 14 can be operated freely as before, and can also be easily set in a position where it can be easily operated.

In the first embodiment described above, the guide track 3 is rotatably attached to the side wall 1, but the present invention is not limited to this. For example, as in the second embodiment of the present invention shown in FIG. Guide track 3
Fixing brackets 41 may be provided on the upper surface of both ends of the test chamber, and these brackets 41 may be fastened and fixed to the ceiling 42 of the examination room via screws 43.

〔Effect of the invention〕

According to the present invention described in detail above, the burden on the operator during endoscopy can be reduced, and the feeling of fatigue can be significantly reduced. In addition, the hanging position and height of the endoscope can be freely adjusted, allowing the practitioner to freely operate the endoscope as before, and also to easily set it in a position that is easy to operate. This has the advantage of maintaining good operability of the endoscope.
