Description

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

Since the large intestine has a more complex shape than other organs that can be subjected to endoscopic examination, high-quality techniques are required to insert an endoscope into the large intestine. Therefore, it is extremely dangerous for medical scientists, medical students, etc. who are inexperienced in operating endoscopes to fully acquire the skills using a colon model before testing patients.

It was simply attached to form a predetermined shape.

That is, the large intestine model is exposed to the outside, and the operator practicing insertion can see the large intestine model at any time.

Therefore, at first, the surgeon looks through the eyepiece of the endoscope to determine the shape of the colon model and practices insertion, but as the endoscope is inserted, the surgeon looks through the eyepiece. When it becomes difficult to distinguish the shape of the large intestine model just by looking at it, people tend to take their eyes off the eyepiece and look at the large intestine model.

On the other hand, when an endoscope is actually inserted into a patient's large intestine, the large intestine is covered by the abdominal wall and cannot be seen, and the illumination light emitted from the endoscope can only be seen passing through the abdominal wall. Therefore, if you can easily see the colon model like the insertion practice device mentioned above, it is difficult to insert the endoscope while looking through the eyepiece, which is the technique required when examining an actual patient. The disadvantage was that it was not possible to master the technique of inserting the tube into the large intestine reliably.

This invention was made based on the above circumstances, and its purpose is to cover the large intestine model with an integral cover so that it cannot be seen, thereby making it possible to learn the techniques required for actual endoscopy. An object of the present invention is to provide a colonoscope insertion training device that enables the user to perform the following exercises.

An embodiment of the present invention will be described below with reference to FIGS. 1 to 4. First, FIG. 1 shows a state in which an operator 2 is practicing inserting an endoscopy for the large intestine@3 using an insertion training device 1. The endoscope 3 includes an operating section 4 and an insertion section 5, and the insertion section 5 is inserted into the insertion training device 1 as described later.

In addition, the operation section 4 is provided with an air/water supply button 5m, a suction button 5b, an eyepiece section 6, an angle operation knob 7, etc., and is connected to a universal cord 8, and the end of this universal cord 8 is connected to a light source device.

The insertion training device 1 has a mounting plate 13 as shown in FIG.
and a large intestine model 14 mounted on this mounting plate 13. 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 I4 has a rectal region 15, a sigmoid colon region 16,
A descending colon section 17, a transverse colon section 18, an ascending colon section 19, an ileum section 20, and an appendix section 2 are formed in sequence, and the upper and...
The distal end of the ileal section 20 is sealed with a removable stopper 22. A first membrane body 23 and a second membrane body 24, which correspond to mesentery, are connected to the sigmoid colon part 16 and the transverse colon part 18.

J ≠ These membrane bodies 2)/, 2/ are removably fixed to the mounting plate 13 with screws 27, 27 via presser members 26, 26. Further, on both sides of the mounting plate 13, a first support 28 and a support 29 corresponding to the retroperitoneum are erected, and through holes 28m are bored in these supports 28°29.
The descending colon part 17 and the ascending colon part 19 are inserted through and supported by 2ga. Furthermore, a third support 30 corresponding to the anus is erected at one end of the mounting plate 13, and a through hole 10a formed in the third support 30 has a rectum as shown in FIG. The distal end of section 15, ie, the anal region 31, is inserted. The end portion of the elastic membrane forming the anal portion 31 is folded back so as to be joined to the peripheral portion of the through hole 301 of the third support body 30. And at this folded end,
An elastic member 33 made of rubber or the like in a flat plate shape and having an insertion port 32 with a smaller diameter than the insertion portion 1 of the endoscope 3 in the center of the elastic member 33 brings the peripheral parts into airtight contact. The elastic member 33 is a frame-shaped body 35 that is detachably attached to the third support body 30 by a hinge 34.
The peripheral portion is clamped and fixed with the third support body 30. Therefore, if the insertion portion 1 of the endoscope 3 is inserted into the large intestine model 14 through the insertion port 32 of the elastic member 33, the insertion port 32 is sealed by the insertion portion 1, so that the inside of the large intestine model 14 is airtight. state. Further, on both sides of the other end of the mounting plate 13, a first presser body 3 corresponding to a liver is provided.
6 and a second presser body 37 corresponding to the spleen are erected.

In addition, the large intestine model 14 provided on the mounting plate 13 is attached to the first
As shown in the figure and FIG. 4, it is covered with a cover unit 38.

This cover unit 38 is made of a flexible material that deforms according to the movement of the large intestine model 14 when the insertion portion β is inserted into the large intestine model 14, and the shape of the large intestine model 14 cannot be determined. , is formed of a material such as cloth or a synthetic resin sheet that allows the illumination light emitted from the insertion section 5 and transmitted through the large intestine model 14 to be slightly discernible. That is, the cover unit 38 is made of a material that exhibits substantially the same condition as the patient's abdominal wall. The insertion training device rt11 covered by the cover unit 38 is
As shown in the figure, it is placed on a mounting table 39.
