An invention according to the re-use prevention of varicose therapy device, a transparent coating 3 which covers the elongate member 2, provided in the fixed member 15, a first aspect of the present invention, the long and the coating fluid it is preferable that by and characterized by comprising an introduction part for introducing between the jaws members, inspecting the body fluid which has entered between the elongate member and the coating material, varices treatment device is used it can be possible to determine, and to prevent reuse. A second invention is characterized by A an invention relating to the insertion ease into a vein varix treatment device, it was a larger diameter than the insertion direction of the proximal end portion of the insertion direction intermediate portion of the insertion guide portion, It is possible that during insertion, it is difficult to pull it out from the vein insertion guide member 5 is engaged with the intermediate portion 5b the end B1 of the vein. An invention according to varices treatment instrument equipped with a second varicose veins stripping member and the first varices peeling member, the third invention, using the varicose veins stripping member having different diameters to fit the thickness of the blood vessel By, it is possible while suppressing the invasion and reliably peeled from the living tissue according to the thickness of the vein.第1の発明は、静脈瘤治療具の再使用防止に係る発明であって、長尺状部材2を被覆する透明なコーティング材3と、固定部材15に設けられ、体液をコーティング材と長尺状部材との間に導入させる導入部を備えたことを特徴とし、コーティング材と長尺状部材との間に侵入した体液を目視することにより、静脈瘤治療具が使用されたものであることを判断することができ、再使用を未然に防止することができる。第2の発明は、静脈瘤治療具の静脈への挿入容易化に係る発明であって、挿入ガイド部の挿入方向中間部を挿入方向基端部よりも大径に形成したことを特徴とし、挿入する際に、静脈の端部B1を中間部5bに係合させて挿入ガイド部材5を静脈から抜けにくくすることができる。第3の発明は、第1静脈瘤剥離部材及び第2静脈瘤剥離部材を備えた静脈瘤治療具に係る発明であって、血管の太さに合わせて径の異なる静脈瘤剥離部材を使用することにより、侵襲を低く抑えながら、静脈を太さに応じて生体組織から確実に剥がすことができる。
