【発明の詳細な説明】
(イ) 産業上の利用分野
この発明は、脳内血腫や脳膿瘍の手術において
血腫や膿汁の排出を円滑かつ容易に徐々行えるよ
うにしたチユーブに関する。[Detailed Description of the Invention] (a) Field of Industrial Application This invention relates to a tube that allows hematoma and pus to be gradually and smoothly drained during surgery for intracerebral hematomas and abscesses.
(ロ) 従来の技術

た。(b) Conventional technology The conventional tube (Fig. 1) is simply a tube with several drainage holes 1 drilled in it, and it is impossible to adjust the position of the holes and the number of holes. When it became occluded, it was impossible to remove the material.
(ハ) 発明が解決しようとする問題点
ドレーンチユーブの排出孔の数や位置を調節可
能にし、かつチユーブが閉塞した場合にその塞栓
物質の除去を可能とし、脳内の血腫や膿汁の排出
を円滑かつ容易に行うことを目的とする。(c) Problems to be solved by the invention The number and position of the drainage holes in the drain tube can be adjusted, and when the tube is occluded, the embolic material can be removed, and hematoma and pus in the brain can be drained. The purpose is to do it smoothly and easily.
(ニ) 問題点を解決するための手段
この発明を図面にもとづいて説明すれば次のと
おりである。(d) Means for solving the problems This invention will be explained as follows based on the drawings.
第１図示のものは、従来のチユーブで、先端に
数個の排出孔１があいているのみで、これを脳内
の血腫腔や膿瘍内に設置した場合、血腫や膿汁な
どの粘張性のある液体の排出には困難をきたし
た。また血腫塊や膿の塊によつてチユーブが閉塞
することが多かつた。 The tube shown in the first diagram is a conventional tube with only a few drainage holes 1 at the tip.If this tube is installed in a hematoma cavity or abscess in the brain, it will prevent viscous discharge such as hematoma or pus. Difficulties were encountered in draining liquids containing liquid. In addition, the tube was often occluded by hematoma or pus.
第２図示は、これらの欠陥を除去するため今回
発明したチユーブであるが、外筒Ａの先端から排
出孔１を規則的に開け、その外筒Ａ内にスライド
可能な中空状の内筒Ｂを嵌着した。 The second illustration shows a tube that was invented this time to eliminate these defects, and it has a hollow inner tube B that can be slid into the outer tube A by regularly opening discharge holes 1 from the tip of the outer tube A. was fitted.
(ホ) 作用
従つて内筒Ｂの引き抜の操作加減によつて外筒
Ａの排出孔１と、内筒Ｂの排出孔２の数と位置と
の調節が可能であり、血腫や脳汁は内筒Ｂより排
出できる。(E) Effect Therefore, the number and position of the discharge holes 1 of the outer tube A and the discharge holes 2 of the inner tube B can be adjusted by adjusting the pull-out operation of the inner tube B, thereby preventing hematoma and cerebral fluid. can be discharged from inner cylinder B.
すなわち第６図は実施例図に示すもので患部５

の広い範囲（Ａ−Ｂ）に排出孔１に設置できる。
また解放した孔が血腫や膿汁にて閉塞した場合、
内筒Ｂを先端部まで挿入することによつて、それ
らを排出物砕き再開通させることが可能となる。 In other words, FIG. 6 is an example diagram showing the affected area 5.
The drainage hole 1 can be installed in a wide range (A-B) within the hematoma cavity (see FIGS. 3 to 5).
In addition, if the released hole becomes blocked by hematoma or pus,
By inserting the inner tube B up to the tip, it becomes possible to crush the waste and reopen the tubes.
(ヘ) 発明の効果
この発明は以上説明したように、脳内に設置し
たチユーブの先端の排出孔や位置を調節する事が
可能であり、またチユーブが閉塞した場合にて

手術後顕著な治療効果を発揮すること大なり。(F) Effects of the Invention As explained above, this invention makes it possible to adjust the discharge hole and position of the tip of the tube installed in the brain, and even if the tube is occluded, it is possible to remove the obstructing substance. Since it is possible to crush and recanalize, in the case of surgery for intracerebral hematoma or brain abscess, it is possible to smoothly drain hematoma, pus, etc.
It has a great effect on the treatment after surgery.
