要約
(EN)
A medical treatment instrument, comprising a rotary cutter (3) and another rotary cutter for medical treatment having a cutting surface outer diameter larger than the maximum cutting surface outer diameter of the rotary cutter (3) (initial cutting rotary cutter), wherein when a blood vessel stenosed site (2) is further increased in diameter, the initial cutting rotary cutter (3) is temporarily extracted to the outside of a body together with a drive shaft (4) and a fixed sheath (5) along a guide wire (1) and, on the guide wire 1, the rotary cutter for medical treatment is formed integrally with the initial cutting rotary cutter (3) extracted to the outside of the body to increase the outer diameter of the cutter, then the integrated cutter (unit cutter) is inserted again in the body to continuously apply a diameter increasing treatment to the blood vessel stenosed site (2).
(FR)
L'invention concerne un instrument de traitement médical comprenant un élément coupant (3) rotatif, et un autre élément coupant rotatif de traitement médical qui présente un diamètre extérieur de surface coupante supérieur au diamètre extérieur maximum de surface coupante de l'élément coupant (3) rotatif (élément coupant rotatif initial). Lorsque le diamètre d'un site (2) sténosé de vaisseau sanguin est accru, l'élément coupant (3) initial est extrait temporairement d'un corps en même temps qu'une tige (4) d'entraînement et une gaine (5) fixe le long d'un fil-guide (1). Sur le fil-guide (1), l'élément coupant destiné à mettre en oeuvre un traitement médical forme une seule pièce avec l'élément coupant (3) initial extrait du corps, afin d'accroître le diamètre extérieur de l'élément coupant. L'élément coupant (unitaire) intégré est ensuite inséré à nouveau dans le corps pour appliquer de manière continue le traitement consistant à accroître le diamètre du site (2) sténosé du vaisseau sanguin.

 治療器具は、回転カッター3と、この回転カッター3(初期切除用回転カッター)の切削面最大外径よりも大径の切削面外径を有する別の加療用回転カッターとを備える。血管内狭窄部2をさらに拡径する際、初期期切除用回転カッター7をドライブシャフト4及び固定シース5とともにガイドワイヤー1に沿って一旦体外に引き出し、ガイドワイヤー1上で、体外に引き出した初期切除用回転カッター7に、加療用回転カッターを一体化させてカッター外径を拡径する。その後、一体化させたカッター(ユニットカッター)を再度体内に挿入して血管内狭窄部2の継続拡径治療を行う。
