Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an insertion training device for learning techniques for inserting an endoscope into the large intestine.

The shape of the large intestine is more linear than that of other organs that can be subjected to endoscopic examination, and therefore, a high level of skill is required to insert an internal organ into the large intestine. Therefore, it is extremely dangerous for medical scientists, medical students, and the like who are inexperienced in operating an endoscope to thoroughly acquire the technique t1 using a large intestine model before testing a patient.

By the way, in an actual inspection of large M#1, once the insertion section of the endoscope is inserted into the large intestine, air is supplied into the large intestine through this insertion S, making it easier for the insertion section to insert large MIIJ. Moreover, the lining of the large intestine is made to have an observable lumen-like shape. At this time, if too much air is sent into the dog and the inside of the dog, the bent part of the large intestine will bend at an acute angle9, making it impossible to pass the insertion tube through and causing pain to the patient.
'1fc On the other hand, if the amount of air supplied is small, the large intestine will not be fully swollen, and there is a risk that the inserted portion may damage the inner wall of the large intestine.

However, the large intestine model in conventional insertion practice devices is simply a tube shaped like the large intestine with an elastic membrane such as rubber, and is similar to a tribute to air supply through the insertion part of the endoscope. There was no sense of expansion or structure. Therefore, with the conventional insertion MIN direct method, it is only possible to perform M-1', which is simply putting in and taking out the insertion sr.
There was a problem in that it was not possible to learn the techniques required when testing patients near the dormitory, such as air supply, water supply, or suction.

This invention was made based on the above circumstances, and its purpose is to make a large intestine model airtight, and to maintain airtightness even when the insertion section of an endoscope is inserted into this large intestine model. To provide a colonoscope insertion training device that allows students to learn techniques such as air supply as well as simply putting in and taking out an insertion part.

An embodiment of the present invention will be described below with reference to the drawings.

First, FIG. 1 shows a surgeon 2 practicing inserting an endoscope 3 for the large intestine using an insertion line 1 during an operation. It consists of the above-mentioned internal view i13 operation section 4 and insertion section 5, and the insertion section 5 is inserted into the insertion training device KIIIC as described later. In addition, the operation section 4 includes an air/water supply button 5m, a suction button 5b, and a sleep section 6.
, angle operation knob 7, etc. are provided, and a universal cord 8 is connected thereto, and at the end of this universal cord 8 there is a connector 0 connected to a light source device 19.
is provided. The family celebration-3 is connected to an air supply 4 pump (not shown) built in the light source device 9 via this connector 0,
It is connected to the water tank JO& and the suction device 11.

Note that a liquid storage tank 12 is interposed between the suction device #1111 and the connector 0 to store the suctioned dirt and the like.

The insertion training device 1 has a mounting plate 11 as shown in FIG.
and a large intestine model 14 mounted on this mounting plate ZS. The large intestine model 14 is made of a stretchable and airtight elastic membrane made of rubber or the like, just like the real thing. That is, the large intestine model 14 has a rectum s15, a sigmoid colon 16,
Descending colon 17, transverse colon 18, ascending colon 19, -
An intestine section 2o and an appendix section 21 are formed in sequence, and the end of the ileum section 20 is sealed with a detachable stopper 22VC. The sigmoid colon part 16 and the transverse colon part 18 are connected to the membrane bodies 24 (D membrane body 23 and ta2) corresponding to the mesentery. 26.26't- and are removably fixed with screws 21.!1.Furthermore, on both sides of the mounting plate 130, there are supports 28 of 1 and 29 of 2, which correspond to the removed peritoneum. and a through hole 2 bored in these supports 28 and 29.
Descending colon 17 and ascending colon 19 at 8a + 79 m
and are respectively inserted and supported. Furthermore, the mounting plate 13
A third support 30 corresponding to the anus is erected at one end, and a through hole JOa4C is formed in the third support 30.
As shown in FIG. 3, the distal end of the rectal region 15, that is, the anal region j1, is inserted.

The end of the elastic membrane forming the anal part 31 is folded back so as to be joined to the peripheral part of the through hole 30a of the third support body 30. At this folded end, there is an elastic member 13 formed in a flat plate shape made of rubber or the like and having an insertion opening 32 in the center which is smaller in diameter than the insertion part I of the internal a-scope 3, which is attached to the peripheral part. The peripheral part of the frame-shaped body J5rc attached to the air is the above-mentioned third
It is clamped and fixed with a support body 30. Therefore, if the insertion portion l of the endoscope 3 is inserted into the large intestine model 14 through the insertion port 32 of the elastic member 33, the insertion portion l
Since the large intestine model 14 is sealed, the interior of the large intestine model 14 becomes airtight. Furthermore, on both sides of the other end of the mounting plate 13,
A first presser body 36 corresponding to the liver and a second presser body 37 corresponding to the spleen are erected.

On the other hand, the sigmoid colon part 16 and the descending colon part 1 of the large intestine model 14
7. Detectors J8... are provided on the surfaces of the transverse colon 18 and ascending colon 519, as shown in FIG. 2. These detectors J8... are used to detect the pressure inside each upper intestine, and for example, strain gauges are used. It is designed to detect pressure changes. As shown in FIG. 4, level detectors 39... are connected to each of the above-mentioned detectors 36...
These level detectors 39 compare the detection signals from each detector 38 with a setting iron.

Then, when the detection signal becomes larger than the set value, that is, when the pressure inside each intestine of the large intestine model 14 exceeds a predetermined value, the signal is output to the AND-OR circuit 40. 4
When signals are output from all of the three level detectors 39 to the AND-OR circuit 40, the connected PUD 41 sounds to notify the AND-OR circuit 40 that the pressure inside the large intestine model 14 has risen too much. It looks like this.

Furthermore, the large intestine model 14 provided on the mounting plate 13 is covered with a cover 4j, as shown in FIG. This cover unit 42 is designed to improve the transparency of the roots in which the illumination light that passes through the large intestine model 14 slightly fluctuates when the illumination light is emitted from the tip of the insertion part l of the inner intestine @S inserted into the large intestine model 14. It is made of synthetic resin or fabric that has Therefore, although the operator 2 cannot determine the shape of the large intestine model 14, he or she can practice while checking the position of the distal end of the insertion section I. That is, the insertion site can be performed under the same conditions as when inserting the insertion portion j1 into the patient.

The insertion training device 11111 configured in this manner corresponds to the entrance part for inserting the insertion fat of the endoscope 3 into the large intestine model 14, even though the large intestine model 14 has an airtight structure. JJK kidnapping the elastic part of the anus part 3? The insertion port 32, which is marked #, is also formed to have a small diameter, and the insertion port 32fC can be inserted into the insertion portion t' in an airtight manner.

Therefore, if you insert the insertion part Jt into the large intestine mold 14 and then supply air through this insertion part If, the upper large intestine 7 del 14 will expand in the same way as the real large intestine, so practice air delivery. be able to. If you blow too much air during this air feeding practice, the detector 38 will detect this! The operator 2 can recognize that he or she has delivered too much air because the sound 4 sounds. Also, by inserting the insertion part ft into the large intestine model 14 in an airtight manner, only the air can be delivered. In addition, you can practice things like furrowing and water pumping just as you would in real life.

As described above, the present invention allows a large intestine model to be airtightly formed using an elastic layer, and also allows the insertion part to be airtightly inserted into the entrance part formed in the large intestine model into which the insertion part of an endoscope is inserted. Since the elastic member is provided, the large intestine model can be expanded in the same way as the real one by supplying air into the large intestine model through the insertion section. Therefore, according to such an insertion practice device 11Tf-,
In addition to simply practicing inserting and removing the insertion tube, you can also practice air supply, suction,
Students can also practice skills that are essential for actual patient examinations, such as pumping water.
