2. Description of the Related Art When an endoscope is simply inserted from the anus during endoscopy of the large intestine or small intestine, it may be difficult to insert the endoscope into the S-shaped colon just before the anus and deeply. Not a few. Therefore, in order to shorten and straighten the S-shaped colon, an insertion aid generally called a sliding tube is used.

FIG. 16 shows a conventional sliding tube 90. The sliding tube 90 has a thickness enough to allow the insertion portion of the endoscope to pass therethrough, and is a simple pipe having a certain degree of flexibility and having a length of about 40 cm. It is formed a little thick so as not to enter.

Further, a sponge material 93 having a slit 92 formed in the center by impregnation with a lubricant is provided in a base 91.
Are arranged, and the endoscope insertion portion pushes and spreads the slit 92 to pass therethrough.

[0006] As a general procedure, first, the sliding tube 90 is arranged so that the colon is straightened using the insertion portion 2 as a guide.
The insertion section 2 passed through the inside is gradually pushed in while pushing and pulling.

In order to insert the insertion section 2 into the large intestine in this manner, it is necessary to inflate the large intestine to some extent by sending air into the large intestine by an air supply system provided in the endoscope. The pressure in the large intestine increases.

As a result, the air in the large intestine blows out like a fart through the gap between the anus and the sliding tube 90 and the gap between the sliding tube 90 and the insertion section 2. In such a case, if air is not released from the large intestine, the patient will feel great pain, and it is inevitable to release air from the intestine.

However, when air is blown out from the anus in this manner, feces dissolved in a laxative or the like and turned into a liquid form are blown out together with the air. When air is blown out, as shown in FIG. 18, the slit 92 portion of the sponge material 93 is opened and the air is blown out from there instantaneously, so that the feces mixed with it spatter over a wide range in many cases. .

When the insertion portion 2 is pushed and pulled, feces are mixed with the lubricant transferred from the sponge material 93 in the pulled-out portion, so that the operator's hands become dirty. Similarly, when the insertion section 2 is pulled out of the anus after the endoscope examination, the operator's hand is similarly stained with feces.

In such a case, the surgeon generally wears rubber gloves, so there is no problem. However, in many cases, the operator has to touch surrounding devices with his / her hands (gloves) soiled with feces. , And contaminate surrounding devices.

[0012] Therefore, the present invention provides an endoscope capable of performing sanitary endoscopic examination by greatly reducing the contamination of the surroundings by feces when the endoscope is inserted from the anus into the large intestine. It is an object of the present invention to provide a fastener for preventing a waste liquid from scattering from a mirror insertion aid.
