（例えば、特開平２−１２１６４８号参照）2. Description of the Related Art As a conventional thrombus removal technique, a catheter for excision of a tumor is known. This catheter has a dent near the tip of the catheter, puts a thrombus in the dent, and if the thrombus enters the dent, the cutting blade attached parallel to the catheter moves in the catheter lumen, and the thrombus in the dent is inserted into the human body. A technique is known in which the catheter is removed from the body and removed outside the body while being stored in the catheter tip.
(See, for example, JP-A-2-121648)

１５，５１２号）A balloon catheter for removing thrombus is also generally known. With this catheter, a blood vessel is cut open from the outside of the body, the balloon is expanded at the target position in the blood vessel, and the distal end of the catheter is pulled toward the operator side, thereby moving the thrombus to the catheter insertion portion and inserting the thrombus into the catheter. It is to be removed from the part. (For example, US Pat. No. 4,3
(No. 15,512)

９Ｐ．１９８７参照）Further, a balun catheter is inserted into a blood vessel to make the balun rest at the foramen ovale portion and expand the balun.
When the foramen ovale is expanded due to the expansion of the balun, a technique for removing the balun catheter outside the body is known. (See, for example, Japanese Patent Application Laid-Open No. 2-168967) In addition, a balun catheter is inserted into a blood vessel, moved to a target site, the balun is expanded at the target site, and the balun is brought into close contact with the blood vessel wall to improve blood flow. Techniques for stopping and stopping bleeding are known. (For example, Clinical Radiation 32: 167P-16

【発明が解決しようとする課題】従来の技術には、次の
ような欠点があった。第１の技術は、カテーテルにくぼ

が決まっているため、径の合わない血管は使用できな
い。The prior art has the following drawbacks. The first technique has a structure in which the catheter is provided with an indentation, and the thrombus is put into the indentation for excision and storage, and therefore the amount that can be stored in one use is small and the operation must be repeated several times, which is complicated. Soft clots are difficult to store in the dent and difficult to remove. In addition, meandering blood vessels are difficult to remove and there is a risk of removing normal blood vessels. Furthermore, the structure is complicated and expensive. Since the diameter of blood vessels that can be used is fixed, blood vessels that do not fit can not be used.
【０００６】また、第２の技術は、血管を切開してカテ
ーテルを挿入するので、血管損傷が大きく出血が多い。
バルンカテーテルが硬い血栓に当たると破損する。血栓
を移動するためバルンカテーテルであるため、血栓の保
持収納ができず除去に時間がかかる。In the second technique, since a blood vessel is incised and a catheter is inserted, blood vessel damage is large and bleeding is frequent.
The balun catheter will break if it hits a hard clot. Since it is a balloon catheter for moving thrombus, the thrombus cannot be held and stored and it takes time to remove.
【０００７】また、第３の技術には、次のような欠点が
あった。バルンの拡張により卵円孔を拡大させるためバ
ルンが破れやすく、卵円孔周囲が硬い場合は、バルンで
は拡大できない。The third technique has the following drawbacks. The balun is liable to break because it expands the foramen ovale by expansion of the balun, and if the periphery of the foramen ovale is hard, the balun cannot be expanded.
【０００８】また、第４の技術としては、次のような欠

りやすい。また、バルンで止血するため、バルンが破損
しやすく、バルンが球形のため移動しやすく出血部位に
正確に当てにくい。Further, the fourth technique has the following drawbacks. Since the balun catheter is inserted into the blood vessel for a long period of time to stop the blood flow, blood flow cannot be sent to the normal blood vessel at the distal end, and the blood vessel at the distal end is more likely to be damaged than baluncate. Also, since the bleeding is stopped by the balun, the balun is easily damaged, and because the balun is spherical, it is easy to move and it is difficult to accurately hit the bleeding site.

る。EFFECTS OF THE INVENTION Since the present invention has the above-mentioned structure, it is possible to insert a surgical guide wire even if the blood vessel meanders because a) the coil diameter can be changed by operating the operation wire (3). With a single surgical guide wire, it can be used for blood vessels of various diameters. (2) Since the coil diameter can be changed by operating the operation wire (3), the pressure applied to the blood vessel wall can be changed and the thrombus can be safely removed. C) It has a simple structure, is not easily damaged, and is inexpensive. D) Since the surgical guide wire of the present invention has the sheet (5) for storing thrombus, a large amount of thrombus can be retained and removed.

きる。Further, with regard to the second embodiment, since the shape is cylindrical, blood pressure can be supplied to the normal blood vessel while pressure is applied to the bleeding portion from the inside of the blood vessel, and blood flow to the normal blood vessel is reduced, resulting in less post-operative blood vessel damage. . Since the coil (1) serves as a stent at the same time as hemostasis, it also prevents spasms. Further, since the blood flow is secured by the cylindrical coil (1), the patient can move. The simple structure allows for early insertion and removal.
