DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cover holder mainly for an electronic endoscope which is inserted into a body cavity to observe the inside of the body cavity with an endoscope.

[0002]

2. Description of the Related Art An endoscope for observing the inside of a body cavity plays a large role in discovering various diseases, treating affected parts, and the like. Since this endoscope is used by inserting its insertion portion into a body cavity, it is necessary to wash and sterilize the same endoscope before using it for another subject. However, since it takes a sufficiently long time to clean and sterilize the endoscope, there are many problems in the efficiency of the use of the endoscope in the medical field. Therefore, in recent years, the air supply pipeline required for endoscopic observation,
It has been proposed that a disposable cover provided with a water supply pipe, a suction pipe, a forceps channel, etc., and sufficiently cleaned and sterilized be mounted on an endoscope provided with only optical elements and used. ing. Thus, since the cover is disposable, there is no need to consider hygiene of the endoscope itself.

[0003] A cover holder is used for easily attaching and detaching the cover to the cover endoscope as described above in a non-contact state by an operator. Furthermore, in order to easily insert the cover endoscope into the cover, air is supplied to the inside of the cover endoscope insertion channel formed in the endoscope insertion portion cover portion,
This is done with the channel inside expanded.

[0004]

Therefore, in order to mount the cover endoscope on the cover, at least a cover holder and an endoscope cover extender are required. However, various external devices, such as a bed and a light source, are installed in the endoscopic examination room, thereby making the endoscopic examination room narrow. In addition, when the above-mentioned cover holder and endoscope cover extender are installed, there is a problem that the endoscopic examination room is further narrowed.

The present invention has been proposed to solve the above problems, and has as its object to provide a cover holder for a cover in which a cover endoscope can be mounted on the cover in a small space. is there.

[0006]

SUMMARY OF THE INVENTION In order to achieve the above-mentioned object, the present invention provides a cover holding device for holding a cover when the cover is attached to or detached from a cover endoscope. An endoscope cover dilator for supplying air into the formed endoscope insertion channel for the cover is provided, and when the cover is mounted on the cover holder, the endoscope cover dilator and the inside of the cover are provided. A cover holder for a cover to be attached to the cover endoscope so as to communicate with the endoscope insertion channel.

[0007]

As described above, the cover holder has the endoscope cover extender integrated with the endoscope cover extender and the cover endoscope insertion channel when the cover is mounted on the cover holder. Are connected to each other,
The cover can be smoothly attached to the cover endoscope in the minimum space.

[0008]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is an overall perspective view of an endoscope apparatus to which a cover endoscope according to the present invention is connected. In cart 1,
Light source device 2, video processor 3, fluid control device 4, V
Peripheral devices such as the TR 5 and the monitor 6 are stored. The light source device 2 includes a cover endoscope 7 having a universal cord 8.
Connected through. The endoscope 7 for the cover includes:
A cable 9 for inputting a signal output from an image sensor (not shown) provided near the distal end of the insertion portion to the video processor 3 is connected.

The cover endoscope 7 is covered with a cover 10 that covers the cover endoscope 7. The cover 10 includes an insert cover 11, an operation cover 12, and a universal cover 13. The cover 10 is configured such that the insertion section cover 11 is attached to the cover endoscope 7 via a cover holder, which will be described later, that holds the cover 10. The main switch 14 provided on the side of the cart 1 is connected to the light source device 2 described above.
Switch for driving the power supply.

FIG. 2 is a front view of the hanger 15 holding the cover endoscope 7 and a front view of the cover holder 16 holding the insertion portion cover portion 11. Cover holder 16
, A dilator body 1 opened to a cover holding member 16a for detachably mounting the pump 17 and the insertion portion cover portion 11 is provided.
8. An extension tube 19 having one end connected to the pump 17 and the other end connected to the dilator opening 18 is built in. An endoscope cover dilator is constituted by these built-in components. The cover holder 16 is provided with a switch 20 for operating the endoscope cover expander.
In addition, a suction pipe 21, an air supply pipe 22, and a water supply pipe 23 extending to the fluid control device 4 are provided in the insertion portion cover section 11.
Are formed.

Next, the operation of the embodiment constructed as described above will be described. First, the insert holder 11 is held by the cover holder 16. Then, a cover endoscope insertion channel formed in the insertion portion cover portion 11 (FIG.
26) Air is supplied. For that purpose, the switch 20 of the cover holder 16 is turned on, and the pump 17 is operated.
The air is discharged from the dilator opening 18. Then, air is sent into the cover endoscope insertion channel and is opened.

In this case, the switch 2 of the cover holder 16 is
Reference numeral 0 denotes a light source device 2, a video processor 3, a fluid control device 4, a monitor 6, and the like housed in the cart 1 by being configured to operate in conjunction with a main switch 14 provided in the cart 1. The device can also be turned on at the same time. The switch 2 of the cover holder 16
0 may be automatically activated when a switch of a device used for an endoscope inspection such as a light source device 2 or a switch for illumination in an endoscopic inspection room is turned on. .
Alternatively, the endoscope cover expander may be always in the ON state by inserting an insertion plug drawn out of the cover holder 16 or the cart 1 into an outlet. As a result, air is constantly discharged from the endoscope cover expander. In addition, by turning on and off the pump 17 in the cover holder 16 using a foot switch (not shown), the endoscope cover expander can be started and stopped without the operator's hand. Can be made.

FIG. 3 is a sectional view taken along line AA in FIG. According to FIG. 3, the operation of sending air into the cover endoscope insertion channel will be described more specifically. First, the insertion portion cover portion 11 is attached to the cover holding member 16a. Then, the dilator body 18 is automatically click-connected to the endoscope operation section fixing mouth section 24 provided on the hand side of the insertion section cover section 11 by the elasticity of the C-ring 25.

Then, air is sent from the endoscope operating section fixing mouth section 24 to the inside of the cover endoscope insertion channel 26 formed in the insertion section cover section 11. In this manner, the cover endoscope insertion channel 26 to which the air has been sent is in a state of being maximized. Therefore, FIG.
If the cover endoscope 7 shown in A is detached from the hanger 15 and is gradually inserted from the tip of the insertion portion 7a, the insertion operation can be easily performed.

After the cover endoscope 7 is mounted on the insertion section cover section 11, various pipes and the like are connected to the insertion section cover section 11. After that, the operation section other than the insertion section 7a of the cover endoscope 7 and the universal cord are covered with the operation section cover 12 and the universal code cover 13, and preparation for endoscope inspection is completed.

[0016]

As described above, according to the present invention, the cover holder and the endoscope cover extender are integrated, and when the cover is mounted on the cover holder, the endoscope cover extender and the cover inner part are provided. Since the configuration is such that the endoscope insertion channel communicates with the endoscope, the cover can be easily attached to the cover endoscope in a small space, and the efficiency of the endoscope inspection can be improved.
