【考案の詳細な説明】

る提案がされていない。(1) Prior Art Inserting a catheter into a patient is somewhat painful, and it is unavoidable that this poses a great burden to patients who are in poor health. A catheter naturally bends when force is applied during insertion, making it difficult to insert and therefore difficult to manipulate.A guide wire (or stylet, hereinafter the same) is inserted into the catheter, but the position of the catheter to be inserted depends on the organ. It depends on the operator's judgment each time depending on the nature of the catheter and the catheter insertion process, and depends on the operator's level of skill. Therefore, catheters generally have a hole at the tip or side, and the guide wire protrudes from the tip or side hole, causing damage to organs and posing a major safety problem. Furthermore, the use of non-slip materials such as silicone rubber coloral makes it very difficult to insert and remove the guide wire and requires skill. Until now, no significant proposals have been made regarding this point.
(2) 解決すべき問題点
医師が患者に施術する際、細心な注意を怠らな
い場合でも、なおリスクを完全には払拭しきれな
いことが知られている。このため、これに用いる
器具が施術時の危険を生ぜしめないような機能を
有することは極めて重要なことである。(2) Problems to be solved It is known that even when doctors are extremely careful when performing treatments on patients, it is still not possible to completely eliminate risks. For this reason, it is extremely important that the instruments used for this have a function that does not pose any danger during the procedure.
カテーテルの操作にあつても、これによつて患
者の臓器を傷害しないでその目的を達するのでな

考案の目的は、施術者の経験の深浅にも関わら

とするガイドワイヤーを埋設したカテーテルを提
供するにある。 Even when operating a catheter, complete treatment cannot be achieved unless the purpose is achieved without damaging the patient's organs. The purpose of this invention is to provide a catheter in which a guide wire is embedded, which allows a practitioner to easily and safely operate the catheter, regardless of their inexperience.
(3) 問題点を解決する技術手段

とができる。(3) Technical means to solve the problem During the catheter insertion process, the guide wire is inserted close to its tip to avoid bending.
Alternatively, the guide wire may be operated at an opportune time, such as stopping the guide wire in front of the catheter due to the need to bend it slightly, but the catheter may be operated without accidentally protruding the guide wire beyond the tip or side hole of the catheter and injuring the organ. In order to have both appropriate hardness and flexibility depending on the condition of the guide wire, the guide wire is made of a coiled thin wire or a Teflon tube, and the inner core can be inserted and removed freely. If it is embedded and fixed in the tube wall of the catheter, the insertion position of the core can be adjusted, the catheter will not bend, or the embedded coiled wire or Teflon tube will make it much stronger than when using only silicone rubber. At the same time, it is possible to maintain appropriate flexibility.

管壁３に埋設固着する。(4) Example An example of this invention will be explained with reference to figures. 1st
The figure is an explanatory view of a gastrointestinal catheter equipped with the features of this invention, and Figure 2 is a sectional view taken along the line A-A in Figure 1.As shown in Figure 3, a coiled wire or Teflon tube 12 is A metal core 13 is formed to be insertable or removable, and is embedded and fixed in the tube wall 3 of the catheter.
この場合、カテーテルの太さによつてワイヤー
又はテフロンチユーブ１２の一部が完全には埋設
できないときは、該部分を管壁３と同質材で被覆
すればよく、カテーテルの断面が楕円形となつて
も、施術上の支障はない。 In this case, if a part of the wire or Teflon tube 12 cannot be completely buried due to the thickness of the catheter, it is sufficient to cover the part with the same material as the tube wall 3, and the cross section of the catheter is oval. However, there is no problem with the procedure.
勿論、この考案は、消化器系用カテーテルに限
られるものではなく、用途に応じたカテーテルに
応用することができる。特に端部１のないカテー
テルに有効である。 Of course, this invention is not limited to catheters for the digestive system, but can be applied to catheters depending on the purpose. This is particularly effective for catheters without an end portion 1.

こともなく、不測の事故を避けることができる。(5) Effects of the present invention According to this invention, as mentioned above, the guide wire is formed as a coiled wire or a Teflon tube and a separate core, and the core does not bend when inserted deeply into the catheter. Moreover, even when the catheter is removed, a catheter that is stronger than previous catheters can be obtained, and the guide wire is not likely to protrude from the tip or side hole of the catheter and injure organs due to the operator's carelessness. This allows you to avoid unexpected accidents.
