ルーン付カテーテルに関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention provides a treatment device that enables long-term operation without stopping the blood flow when performing endoscopic or laser treatment on the inner wall of a blood vessel or heart where blood flow is always present. This invention relates to a catheter with a transparent balloon for insertion.
（従来技術）
血液循環系の器官には常時血流が存在しているため器官
の内壁を内視又は外科的に治療するには観察部位と光学
系との間の血液を排除した状態でしなければならない。(Prior art) Blood circulation always exists in organs of the blood circulation system, so in order to treat the inner wall of the organ endoscopically or surgically, it is necessary to exclude blood between the observation site and the optical system. There must be.
このため従来から内視カテーテル先端部の視野範囲に生
理食塩水やぶどう糖液をガイデイングカテーテルを介し

にフラッシュチャンネルを設けたカテーテルが提案され
ている。For this reason, conventional methods have been proposed in which blood is removed by squirting physiological saline or glucose solution into the field of view at the tip of an endoscopic catheter through a guiding catheter, or a catheter with a flush channel provided inside the catheter. There is.
しかし、いずれの場合も血液の逆流或はファイバー周囲
の血流によって視野は短時間のうちに妨げられて充分な
観察がリアルタイムで実現できないのが現状であって、
間欠的に得られた良視野観測画像を再現するには高度な
画像処理が必要になるのである。However, in any case, the field of view is quickly obstructed by backflow of blood or blood flow around the fiber, making it impossible to achieve sufficient observation in real time.
Advanced image processing is required to reproduce the good field of view observation images obtained intermittently.
更に、このような方法では操作時間に限界があり、長時
間の観察及び治療は不可能である。Furthermore, such a method has a limited operating time, making long-term observation and treatment impossible.
（目的）
本発明は、観察又は治療部位に透明膨脹バルーンを密着

血流用空間が形成されるものである。(Structure) The balloon-equipped catheter of the present invention includes a transparent inflation balloon, which is formed by a transparent inflation bag and an inflatable annular tube or a rod-shaped tube attached to the appropriate position of the inflation bag in communication with each other, and is attached to the distal end of the catheter. By injecting the inflation material, the surface other than the tube attachment portion is pressed against the observation site, and a blood flow space is formed between the tubes or between the tube and the inflation bag.
本発明において透明バルーンは、伸縮性のあるゴム質膜

又はプリズムを膨張袋内において回動及び進退可能に位
置させるものである。The fiber bundle inserted into the catheter consists of an image guide fiber, an illumination fiber, and a laser introduction fiber, and has a lens and/or fiber attached to its tip.
Alternatively, the prism is positioned so that it can rotate and move forward and backward within the expansion bag.
レンズ又はプリズムは所望する視野範囲に応じて選択さ
