た。 FIG. 1 shows a folding portion in a conventional endoscopic catheter device, which is cited as an example of an endoscopic treatment tool. That is, this is catheter 1
A snapping member 2 made of a single elastic cylindrical body is fitted around the proximal end of the catheter 1.
Each proximal end of the stopper member 2 is fixed to the base 3. Therefore, a gap 4 is created between the snapping member 2 and the catheter 1, which opens to the outside at the distal end thereof. Therefore, if this catheter device is cleaned or immersed in a disinfectant solution,
Liquid will enter into the gap 4. Moreover, since the gap 4 is open only at one end, the liquid once inside cannot be easily discharged to the outside. In particular, medical solutions and the like are usually toxic to living organisms, and the post-treatment work required to drain them is extremely troublesome.
本考案は上記事情に着目してなされたもので、
その目的とするところは折止め部材の内側に液体
が入り込んでもこれを迅速かつ容易に排出できる
衛生的な内視鏡用処置具を提供することにある。 This invention was made with attention to the above circumstances,
The purpose is to provide a sanitary endoscopic treatment tool that can quickly and easily drain liquid even if it enters the inside of the stopper member.
以下、本考案の一実施例を第２図にもとづいて
説明する。 Hereinafter, one embodiment of the present invention will be described based on FIG. 2.
この実施例は内視鏡用カテーテル装置１１を示
すものである。このカテーテル装置１１は可撓性
をもつように合成樹脂によつて形成された管状部
材であるカテーテル１２と、このカテーテル１２
の基端に嵌入固着する口金１３とからなる。上記

てある。この折止め防止部材１５の基端１５ａは
上記口金１３の接続端１３ａに液密的に外嵌して
いる。 This embodiment shows an endoscopic catheter device 11. This catheter device 11 includes a catheter 12 which is a flexible tubular member made of synthetic resin, and
It consists of a base 13 that is fitted into and fixed to the base end of the base. The cap 13 is for connecting an injection tool (not shown) or the like. Further, a breakage prevention member 15 made of an elastic tube is fitted around the outer periphery of the breakage prevention portion 14 near the proximal end of the catheter 12 . The proximal end 15a of the anti-folding member 15 is fitted onto the connecting end 13a of the base 13 in a liquid-tight manner.
そして、上記カテーテル１２の外周面と上記折
止め防止部材１５の内周面との間には間隙１６が
形成されている。この間隙１６は上記構成である

つて配列される複数の排出用孔１７…が形成され
ている。この排出用孔１７…は上記間隙１６の末
端部に連通するようになつている。しかして、上
記間隙１６はその先後両端において外部に連通し
て開口するようになつている。 A gap 16 is formed between the outer peripheral surface of the catheter 12 and the inner peripheral surface of the anti-folding member 15. Since this gap 16 has the above configuration, it opens to the outside at the distal end side of the catheter 12. Further, the gap 16 on the proximal end side of the catheter 12 is sealed because the catheter 12 and the breakage prevention member 15 are closely fitted to the mouthpiece 13. By the way, a plurality of discharge holes 17 are formed in the peripheral wall of the proximal end portion of the anti-folding member 15 and arranged along the circumferential direction thereof. The discharge holes 17 communicate with the distal end of the gap 16. Thus, the gap 16 is opened to communicate with the outside at both its front and rear ends.
しかして、上記カテーテル装置１１を洗浄消毒
することにより上記間隙１６には洗浄水や薬液が
侵入することがある。しかし、間隙１６の両端が
外部に開口しているので、カテーテル装置１１を
縦にしたり振つたりすれば内部の液体はいずれか
の開口から容易にかつ迅速に外に排出する。さら
に、一方の開口部分から空気を吹き込めばさらに
容易に排出させることができる。このため、上記
液体の排出操作がきわめて容易になる。 When the catheter device 11 is cleaned and disinfected, cleaning water or a chemical solution may enter the gap 16. However, since both ends of the gap 16 are open to the outside, when the catheter device 11 is held vertically or shaken, the liquid inside can be easily and quickly drained out from either opening. Furthermore, if air is blown through one of the openings, it can be discharged even more easily. Therefore, the operation for discharging the liquid becomes extremely easy.
なお、上記実施例では排出用孔１７…を折止め
防止部材１５の末端部分にのみ形成するようにし
たが、本考案はこれに限定されず、たとえば折止
め防止部材１５の中間途中部分などにも分散して
設けてもよい。また、本考案は上記カテーテル装
置に限らず、鉗子などその他の内視鏡用処置具に
も同様に適用できるものである。 In the above embodiment, the discharge holes 17 are formed only at the end portion of the anti-folding member 15, but the present invention is not limited thereto. They may also be provided in a dispersed manner. Further, the present invention is not limited to the above-mentioned catheter device, but can be similarly applied to other endoscopic treatment instruments such as forceps.
以上説明したように本考案によれば、管状部材
と折止め防止部材との間の間隙に液体が入り込ん
でも、これを容易かつ迅速に排除することができ
る。したがつて、洗浄消毒後に上記液体を除去す
る後処理に手間がかからず、かつ確実に排除でき
るので、残つた薬液などで術者の手が炎症を起す
などの事態を未然に防止できる。また、本考案の
手段によれば、折止め防止部材の折止め防止効果
をほとんど損なうことなく目的を達成できる。 As explained above, according to the present invention, even if liquid enters the gap between the tubular member and the anti-folding member, it can be easily and quickly removed. Therefore, post-processing to remove the liquid after cleaning and disinfection does not require much effort and can be removed reliably, making it possible to prevent the operator's hands from becoming inflamed due to the remaining chemical solution. Moreover, according to the means of the present invention, the object can be achieved without substantially impairing the anti-folding effect of the anti-folding member.
