Abstract

La présente invention est pourvue : d'un guide (22) qui s'étend vers l'avant et vers l'arrière le long d'un centre axial (T) et qui a une forme circulaire ayant un diamètre inférieur au diamètre de la lumière (3) d'une valvule veineuse (1) ; une tige de raccordement (24) qui s'étend vers l'avant à partir de l'extrémité avant du guide ; un dispositif de coupe (30) d'extrémité de pointe qui est relié à l'extrémité avant de la tige de raccordement ; et un fil flexible (26) qui s'étend vers l'arrière à partir de l'extrémité arrière du guide. Le dispositif de coupe d'extrémité de pointe possède, au niveau de l'extrémité arrière, une partie extrémité arrière (32) qui possède une surface courbe incurvée vers l'arrière. La partie extrémité arrière possède quatre cônes (34) à lame coupante en forme de pyramide approximativement triangulaire ou plus possédant des espaces entre eux dans le sens circonférentiel du centre axial. Les cônes à lame coupante possèdent chacun un sommet (42) qui est orienté vers l'arrière et utilisent la surface périphérique externe (36) du dispositif de coupe d'extrémité de pointe comme une des surfaces latérales qui est en contact avec le sommet, puis des lames à bord tranchant (40a, 40b) sont formées par les trois côtés qui viennent du sommet. L'un des trois côtés s'étend à partir du sommet vers le centre axial.
