Description

DETAILED DESCRIPTION OF THE INVENTION (a) Technical Field of the Invention The present invention relates to a large intestine treatment device used to treat diseased large intestines.

(Background of oral technology) In recent years, as the Japanese diet has shifted to a Western-style diet, the number of colon-related diseases that are common in Europe and the United States has increased. desired.

(C) Conventional technology and problems There are various diseases of the large intestine, such as catarrh of the large intestine, ulcers where the mucous membrane tissue swells, and tumors that develop in the epithelial tissue.In general, mild diseases such as catarrh of the large intestine are treated with medication. A treatment method is performed. On the other hand, malignant ulcer, II! For diseases such as tumors, radiation therapy to eliminate the diseased area or surgery to remove malignant tissue is used.

However, such a method not only places a heavy burden on the patient but also has many side effects. Moreover, it also comes with great danger.

(Jin) Purpose of the Invention The present invention was made in view of the above, and its purpose is to provide a method that does not impose a large burden on patients, has no side effects,
It is also an object of the present invention to provide an instrument for treating the large intestine that can be treated without any danger.

(G) Structure of the Invention The basic structure of the present invention to achieve the above object is an endless double cylinder consisting of a flexible outer cylinder and an inner cylinder filled with a solution-like or gel-like fluid. A flexible insertion rod is coated with a therapeutic agent on its entire surface and can be moved forward or backward in the large intestine by reversing the outer cylinder and inner cylinder, and is detachable from the inner cylinder of the endless double cylinder. It was inserted into.

(f) Examples of the invention Embodiments of the present invention will be described in detail below with reference to the drawings.

FIG. 1 shows an embodiment of the large intestine treatment instrument according to the present invention.

The present invention provides an endless duplex tube A filled with a fluid 3 by continuously reversing the outer tube 1 and inner tube 2 as shown in FIGS. 2 and 3. An insertion rod B for moving the tube A forward or backward in the large intestine C shown in FIG. 5 is removably inserted.

The endless double cylinder A is an outer cylinder 1 of a tube with a constant diameter.
It consists of a flexible double tube formed by bonding together an inner tube 2 that is folded inward, and is filled with a fluid 3 in the form of a solution or gel. This endless double cylinder A is made of, for example, a thin rubber film or a synthetic resin film,
The outer diameter is 250φ to 35wmφ, corresponding to the inner diameter of the large intestine. Also, its length is for sigmoid colon and descending colon.

An appropriate length is selected depending on the use for the transverse colon, etc. In addition, the solution-like or gel-like fluid 3 filled therein
For example, a simple solution of water, a simple solution of glycerin, a mixed solution of water and glycerin, a simple liquid silicone, a gel-like simple silicone liquid, etc. are used.

The insertion rod B is a flexible rod made of a circular tube or a round rod that is longer than the endless double cylinder A, and is detachably inserted into the inner cylinder 2 of the endless double cylinder A. By moving this insertion rod B back and forth, the outer cylinder 1 and the inner cylinder 2 of the endless double cylinder A are continuously reversely moved, so that the endless double cylinder A can move forward or backward. In addition, this insertion rod B is made of rubber or synthetic resin and has a diameter of, for example, 10 Minφ to 16 mm.

When treating a diseased large intestine, the patient should eat a light meal or have a liquid meal the day before the treatment, forbid breakfast on the day of treatment, and administer an enema or defecate before treatment. As shown in Fig. 2, the insertion rod B inserted into the endless double cylinder A is moved back and forth, and while the outer cylinder 1 and inner cylinder 2 are moved inverted, a therapeutic drug according to the disease is applied to the entire surface of the rod. (For example, an ointment) should be applied evenly.

Next, apply the tip of the endless double tube A of the large intestine treatment instrument to the anus 4 of the large intestine C shown in FIG.
Insert the insertion rod B inserted into the inner cylinder 2 further back. Since the endless double tube A is filled with the fluid 3 and is flexible, it can be easily and smoothly bent and inserted even into the complicatedly curved intestine. By inserting the insertion rod B, the outer tube 1 and the inner tube 2 are continuously reversely moved, and the endless Ni-4 type tube A moves forward, and the outer tube 1 is attached to the inner wall surface of the large intestine C that is in contact with the outer tube 1. The therapeutic agent applied to the side is transferred from the rectum 5 to the sigmoid colon 6, from the sigmoid colon 6 to the descending colon 7, and so on.
．． Descending colon7. It is sequentially applied to the transverse colon 8° and ascending colon 9. The therapeutic agent is then evenly applied to the diseased intestinal area. After that, insert the endless double tube A into the flame 1IIC and hold it there for a certain period of time. After that, by pulling back the insertion rod B, the outer tube 1 and the inner tube 2 are reversely moved in the opposite direction. The heavy tube A is retracted and pulled out from the large intestine C. In this way, the therapeutic agent is appropriately applied within the large intestine C. As mentioned above, since the endless double cylinder A is a flexible double cylinder filled with the fluid 3, the bent sigmoid colon curvature 10 and the left colon flexure (frontal curvature) 11
．． Passing through the right colonic flexure (hepatic curvature) 12 without any trouble,
It can be inserted easily and in a short time (instantly). Therefore, the therapeutic agent can be applied without placing any burden on the patient.

Depending on the disease, it can be used for the sigmoid constriction or for the descending colon.

Needless to say, one for the transverse colon is used.

In addition, according to such colon treatment, the therapeutic agent is simply applied to the inner wall of the colon C using the endless double tube A, so the tissue is not destroyed and cannot be removed by surgery. do not have. Therefore, there are no side effects and the risks are extremely low.

FIG. 4 shows another embodiment of the large intestine treatment instrument of the present invention.

This example shows the outer cylinder 1 and inner cylinder 2 of the endless double cylinder A.
This is a case in which annular protrusions 13 are provided at equal intervals on the surface of.

The annular protrusion 13 has a width of, for example, 1 to 1.51 cm.
In 1, the protrusion amount is about 1 crane, and they are set at intervals of 10 m to 15 days.

By providing the annular protrusions 13 on the surfaces of the outer tube 1 and the inner tube 2 in this way, the therapeutic agent can be better retained and the therapeutic agent can be delivered into the intestines more reliably.

The protrusions 13 provided on the surfaces of the outer cylinder 1 and the inner cylinder 2 are not limited to annular protrusions, but may also include intermittently annular protrusions, truncated conical protrusions, or other protrusions as necessary. is used.

Further, for the insertion rod B inserted into the endless double tube A, a round rod made of rubber or synthetic resin is used instead of the circular tube as in the above embodiment. Further, the insertion rod B may be a small-diameter endless double tube, such as the endless double tube A, consisting of an outer tube and an inner tube. Incidentally, these insertion rods B are naturally used not only in this example but also in the above embodiments.

(G) Effects of the Invention As described above, according to the present invention, a colon treatment instrument is provided in which a flexible insertion rod is inserted into a flexible endless double tube filled with a fluid. By using
It has become possible to easily apply therapeutic drugs to the complicatedly curved inner wall of the colon, which was previously impossible, and it is now possible to treat patients without placing a large burden on them (and without causing any side effects or risks). It becomes possible to do so.
