ある。[Prior Art] A gastrointestinal catheter is placed in a patient's gastrointestinal tract and performs various functions such as evacuation of contents, suction, irrigation, injection of drug solutions and contrast media, decompression of intragastric pressure after surgery, and nutritional support. The conditions that a catheter must meet are: (1) It should be easy to insert, that is, it should pass quickly through the throat and not coil around the esophagus, it should not damage internal organ lumens, and it should be easy to contrast; It needs to be able to enter the digestive tract quickly, and for this purpose, it needs to be able to easily pass through the pylorus of the stomach, and it needs to be able to easily advance into the duodenum by peristalsis, and it is also required to be able to be reinserted. This is because the patient may consciously or unconsciously withdraw the catheter.

このためには、導入チユーブは弾性と適度の硬
さがあり、胃に到達後は蠕動作用により進入する
ため、非常に柔軟性に富むことが好ましい。 For this purpose, it is preferable that the introduction tube has elasticity and appropriate hardness, and is very flexible since it enters the stomach by peristalsis after reaching the stomach.

構造も複雑で、コスト高となる。 Conventionally, there have been commercially available tubes in which an elastic core for introduction is inserted into a flexible introduction tube to maintain the shape and allow the tube to reach a desired site in the gastrointestinal tract.
The core wire for introduction (mandolin, hereinafter referred to as mandolin) is, for example, JP-A-62-66866.
Twisted wire, ie, a solid metal wire wound into a thin spiral tube, has been used, such as that used in However, this spiral wire undergoes plastic deformation and bends when the displacement exceeds a certain level, impairing its ability to be flexibly delivered to a designated area, or causing the tip to be pulled out from the olive area, resulting in severe damage to the limb. It takes a lot of time and effort. As an improvement method for this, Japanese Utility Model Application No. 60-138547 proposes a method in which at least a portion of a superelastic metal body is attached as an inner core in a flexible substantially tubular body.
Although this device does not have the above-mentioned drawbacks such as curved curls, since the inner core is inserted into the tubular body, there is a limit to the outer diameter of the tubular body, and therefore the thinness of the catheter tube diameter, and the structure is complicated. The cost will be high.

課題を解決できることを見いだし、本考案を完成
するに至つた。[Problems that the invention aims to solve] In view of the shortcomings of conventional mandolins, the inventors conducted various studies on the structure of the mandolin, which is thin, highly elastic, flexible, and resistant to bending, and created a wire rope. It was discovered that the above-mentioned problems could be solved by using a new structure, and the present invention was completed.

A tip hole through which the mandoline cannot penetrate is provided at the tip of the olive, and a side hole is provided at the side of the hole where the intersecting angle between the inner wall surface on the tip side of the olive and the outer surface of the olive is an acute angle, There is also provided a catheter for the gastrointestinal tract, characterized in that the mandoline is a wire rope made by twisting four or more metal wires together.

にできるようにしたものである。 That is, by using the mandoline as a wire rope made of four or more metal wires twisted together, it is possible to quickly enter the desired part of the introduction tube, and to make it easier to insert and withdraw the mandoline from the introduction tube. This is what I did.
マンドリンは自立出来ない導入チユーブに線形

ステンレス鋼線が好適に用いられ、鋼線も使用で
きる。 A mandolin is used to give a linear shape to an introduction tube that cannot stand on its own, and in the present invention, a rope-like structure made by twisting four or more metal wires together is used. As a metal wire,
Stainless steel wire is preferably used, and steel wire can also be used.
ワイヤロープの素線の数は４本以上である必要

のも使用される。 The number of strands in the wire rope must be four or more; if there are three strands, depending on the direction of bending, the rope may be weak, have poor elasticity, and may become bent.
The purpose of the present invention cannot be achieved, and by using four or more, a mandolin with homogeneous directionality, strong stiffness, elasticity, and no bending distortion can be obtained. Wire ropes are also used by twisting several metal wires together to create strands, and then twisting several strands around a core rope.
本考案の１実施例を図面に基づいて説明する。

多少硬くてもよい。 In this embodiment, the introduction tube 2 has an outer diameter of 2.0 mm and an inner diameter of 1.5 mm, and the tube wall includes a contrast line 7 containing 20% barium sulfate as a contrast agent. In addition, the 2 to 3 cm part near the olive is for installing the olive, so make the pipe diameter a little thicker, and
It may be a little hard.
導入チユーブは蠕動を受けるため、できるだけ
柔軟であることが好ましく、軟質プラスチツク材

いものも用いられる。 As shown in FIG. 3, the mandolin 4 has a wire rope 9 extending from the base of the mandolin, which is provided with operating wings 8 if necessary. In addition, the end portion may be curved and used without providing a wing for operation. In this embodiment, the wire rope 9 is made of stainless steel wire 10 with a diameter of 0.2 mm, as shown in the cross-sectional view of FIG.
A wire rope with an outer diameter of 0.6 mm is used by twisting it together. Also used is a wire rope with a large number of strands, such as the one shown in FIG. 5, in which 37 stainless steel strands with a diameter of 0.1 mm are twisted together to form a wire rope with an outer diameter of 0.7 mm.

保するためである。 Next, the olive 3 attached to the tip is
For example, it is made of hard plastic such as polyamide, polypropylene, polyester, etc., and as shown in Figure 6, it has a cylindrical shape, and in this example, it has a length of 15 mm, an outer diameter of 5 mm, an inner diameter of 1.5 mm, and an internal to prevent clogging and prevent the mandolin from punching through.
A tip hole 11 with a diameter of 0.4 mm is provided. Further, a side hole 12 is bored in the side portion as an outlet for the nutrient solution. The inner diameter of the side hole is approximately 2.0 mm. The side hole needs to have an acute angle of intersection between the inner wall surface on the tip side of the olive and the outer surface of the olive, as shown in FIG. That is, when the mandolin is inserted into the olive, even if the tip of the mandolin hits the wall of the side hole, it will not be able to jump out of the side hole, thereby ensuring safety.
なお、必要により、オリーブ及び導入チユーブ

It has the following effects.
(1) ワイヤロープ構造のため、細くしても弾性が
高く、且つ適度の柔軟性に富み、折りぐせが付
きにくい。(1) Due to the wire rope structure, it has high elasticity even when made thin, and has a moderate amount of flexibility, making it difficult to fold.

い。(2) Since the strands on the outer periphery of the wire rope partially contact the inner wall of the introduction tube in a diagonal spiral curve,
When inserting or withdrawing the mandolin, tacking (sticking) due to contact with the inner cavity is less likely to occur.
(3) 素線と素線間の窪み空間が多く、この部分に

It can be smoothly introduced into the specified part of the pipe. Furthermore, the mandolin can be easily pulled out and reinserted, causing almost no pain to the patient, and is advantageous in terms of manufacturing cost, making it extremely useful medically.
