 In recent years, endoscopes have been widely used in the medical field and the like. When an endoscope used in the medical field is inserted into a living body, the observation window provided at the distal end of the insertion section may become dirty due to adhesion of dirt, mucus, etc. on the affected area, and it may not be possible to fully observe it. It For this reason, the endoscope is provided with an air / water supply function of supplying liquid to the observation window for cleaning or manually operating the operator's hand side to blow the remaining water to the air. In addition, this insufflation function is also used when insufflating the body cavity to make it easier to observe the observation site. This air supply and water supply are supplied via an air supply line and a water supply line.

In addition, an endoscope is provided with a suction conduit for sucking and discharging unnecessary dirt, mucus, and the like, and further, for collecting tissue with biopsy forceps, medical treatment with a treatment tool, and the like. In some cases, a forceps channel (treatment instrument channel) is provided so that the forceps can be performed.

In the endoscope used in the medical field as described above, the endoscope once used for a patient or the like is subjected to cleaning or sterilization treatment in order to reliably prevent an infectious disease and the like.

However, it takes time to completely clean and disinfect, not only the workability is poor, but also the use efficiency of the endoscope is reduced.

Therefore, recently, there is a so-called cover type endoscope that covers the endoscope itself with an endoscope cover and discards the endoscope cover for each floor to simplify cleaning and disinfection after use. Has been adopted.

According to this cover-type endoscope, a conduit opening into the body cavity of the patient is provided on the endoscope cover side, and an observing means and an illuminating means that do not open into the body cavity of the patient are provided on the endoscope side. Even with a very expensive video endoscope that uses a solid-state image sensor (SID) that can be easily displayed on a monitor by illuminating it and covering it with a high-quality evaluation and demonstration performance by covering it with an endoscope cover, After use, the video endoscope does not become unclean, and the endoscope cover can be discarded to simplify cleaning and disinfection.

A so-called cover-type endoscope of this type is disclosed, for example, in Japanese Examined Patent Publication No. 2-54734 (US Pat. No. 4,646,722) or US Pat. No. 3,162,190.

[0009]

[Problems to be solved by the device]

Further, a tear bar 41d extending to the lower portion of the tear member 41 is superposed on the endoscope insertion channel 39A formed on the insert cover outer cover 21A, and the lower end thereof is fixed by an adhesive 42. The tearing member 41 and the tearing rod 41d may be separate bodies.

Further, the dilator 6 normally continues to supply air. For this reason, when the function of the dilator 6 is not used, the end of the dilation tube 37 is not connected to the dilation tube mouth 38, but communicates with the outside air as shown in FIG. Then, when the cover endoscope 2B is inserted into the insertion portion cover portion 11A, the end of the expansion tube 37 is pushed into the expansion tube mouth 38 to perform an airtight insertion (fitting) connection. Then, the air supplied from the dilator 6 is sent to the endoscope insertion channel 39A through the expansion tube mouth 38, and the endoscope insertion channel 39A is inflated to facilitate the insertion of the insertion portion 11B.

Next, the operation of the above embodiment will be described.

First, when inserting (attaching) the cover endoscope 2B into the insert portion cover portion 11A of the cover 2, the semi-circular cover holding member 10a provided in the holder 10 fixes the endoscope operating portion. The flange portion at the upper end of the mouthpiece portion 22A is held.

After that, when the distal end of the expansion tube 37 is connected to the expansion tube mouth 38 and the front end of the insertion portion 11B of the endoscope 2B for a cover is inserted into the endoscope insertion channel 39A from the opening 40A, The opening 40A is narrowed by the insertion portion 11B, air is sent into the endoscope channel 39, and the endoscope insertion channel 39A swells.

Then, the tip of the insertion portion 11B is inserted until it comes into contact with the cover observation window 26A provided at the tip of the endoscope insertion channel 39A.

At this time, the latching claw 41b formed on the tearing member 41 formed on the opening 40A is tapered by the mouthpiece mounting portion 22B for fixing the endoscope operation portion provided on the cover endoscope 2B. When the insertion portion 11B abuts on the observation window 26A, the latching claw 41b is formed in the endoscope operation portion fixing mouth portion attachment portion 22B and the recess portion 22b is formed. And the insertion operation is completed.

After the insertion operation is completed, when the end of the expansion tube 37 is removed from the expansion tube mouth 38, the endoscope insertion channel 39A contracts due to its elasticity (the outer diameter of the insertion portion cover outer skin 21A is The outer surface of the insertion portion 11B, that is, the outer cover of the insertion portion 11B is in close contact with the inner surface thereof.

After that, the operation portion 12B of the cover endoscope 2B is covered with the operation portion cover 12A, and the opening end of the operation portion cover 12A of the endoscope operation portion fixing mouth portion 22A of the insertion portion cover portion 11A. The universal cord 13B is covered with the universal cord cover 13A while being closely attached to the upper end, and the above-mentioned cover endoscope 2B is sealed and tested.

Then, when the inspection is completed in a predetermined manner, the grip portion 41a of the tearing member 41 provided on the endoscope operation portion fixing mouth portion 22A of the insertion portion cover portion 11A is grasped and pulled together with the operation portion cover 12A. . Then, the tearing member 41 is cut along the perforations 41c, and the latching claws 41b protruding inward from the gripping portions 41a are formed in the concave portion formed in the endoscope operating portion fixing mouthpiece mounting portion 22B. It comes off from 22B.

When the tearing member 41 is further pulled, the tearing rod 41d of the tearing member 41 tears the endoscope insertion channel 39A of the insertion portion cover 11A and inserts it into the endoscope insertion channel 39A. The insertion portion 11B of the cover endoscope 2B is exposed, and the cover endoscope 2B is taken out.

Since the insertion portion cover portion 11A is positively damaged, it can be determined at a glance whether it is in the used state or the unused state, and misuse can be prevented. Further, the cover endoscope 2B can be easily taken out from the insertion portion cover portion 11A.

In addition, when each cover is fixed with a tape, the tape is peeled off to take out the cover endoscope 2B, and a part of the tape is left on the cover. The status may be displayed.

By the way, as shown in FIG. 5, when the bending operation knob 12b is attached to the bending operation knob shaft 12a provided in the operation portion 12B of the cover endoscope 2B, first, the operation portion 12B is operated. The partial cover 12A is covered. Then, the bending operation knob 12A is attached to the portion of the operation portion cover 12A that is projected by the bending operation knob shaft 12a. Then, the portion of the operation portion cover 12A protruding by the bending operation knob shaft 12a is automatically broken by the bending operation knob 12b, and the bending operation knob 12b is mounted.

Conventionally, when the operation portion 12B of the cover endoscope 2B is covered with the operation portion cover 12A, a hole is previously formed at a position where the bending operation knob shaft 12a provided in the operation portion 12B of the operation portion cover 12A is located. After opening, the bending operation knob 12a was exposed from this hole after coating, and then the bending operation knob 12b was attached to the bending operation knob shaft 12a. Therefore, since the bending operation knob shaft 12a is exposed before the bending operation knob 12b is attached, it is easily contaminated. However, when the bending operation knob 12b is attached as in the embodiment shown in FIG. At the same time, if the operation portion cover 12A is torn and the bending operation knob shaft 12a is exposed, the bending operation knob shaft 12a can be mounted without being contaminated, and the bending operation knob shaft 12a is clean. .

Further, as shown in FIGS. 6 and 7, if the universal cord cover 13A is formed by welding the integral or separate sheet 43 having the first surface 43a and the second surface 43b, it can be formed in a short time. The universal cord cover 13A can be attached to the universal cord 13B and the water supply conduit 28A.

That is, the sheet 43 is placed on the welding table 44a of the cover welding device 44, and the holding portion 29 of the cover endoscope 2B, the connector 15 and the cover 43 are placed between the first surface 43a and the second surface 43b of the sheet 43. The universal code 13B provided between the holding part 29 and the connector 15 and the water supply conduit 28A are interposed and set in the recess 44b formed in the welding table 44a (FIG. 7 (a)).

After that, the heater lid 44c is put on the welding table 44a. Then, in the recess 44d formed in the heater lid 44c, the holding portion 29 covered by the operation portion cover 12A, the connector 15, the universal cord 13B provided between the holding portion 29 and the connector 15, and the water supply conduit. 28A is sandwiched between the first surface 43a and the second surface 43b of the seat 43, and the first surface 43a and the second surface 43b of the seat 43, and the noodles 43a and 43b and the operation portion cover 12A are attached. Heating is started by the heater lid 44c to start welding (FIG. 7 (b)).

Then, when the convex portions 44e provided at both ends of the concave portion 44d of the heater lid 44c are placed on the welding table 44a, the heat from the convex portion 44e causes the first surface 43a of the sheet 43. And the extra portion of the second surface 43b is melted.

After that, the periphery of the sheet 43 is further welded to complete the universal cord cover 13A (FIG. 7 (c)).

Reference numeral 45 is a spacer that is attached to hold the water supply conduit 28A after the water supply conduit 28A is attached to the holder 29.

Further, even if burrs or the like are generated in the fusing part, there is no influence because the universal cord cover 13A is not inserted into the body cavity. Therefore, the surface of the universal code cover 13A needs to be smooth. There is no. Further, the material of the sheet 43 is preferably the same material as the operation portion cover 12A, such as fluororubber, but may be a different material.

Conventionally, the holding portion 29, the connector 15, and the universal cord 13B provided between the holding portion 29 and the connector 15 and the water supply conduit 28A are preliminarily tucked up when the endoscope is used. Although it was covered with the cover 13A, the universal cord 13B is relatively long, and the holding portion 29 and the connector 15 having a relatively large outer shape are attached to both ends of the universal cord 13B. I mastered it. In particular, when installing the universal cord cover 13A between floors, it takes time to put on the cover and the time not involved in the inspection increases, so not only the number of floors per day decreases but also the spirit of the patient undergoing the inspection. However, according to the above-described embodiment, the universal cord cover 13A can be attached in a short time, the usability is good, the number of floor cases per day is increased, and the pain and fatigue of the doctor and the patient are increased. Less.
