Abstract:
(EN) Disclosed are filters (100, 200, 300), comprising main bodies (10, 20, 30) with proximal ends (101, 201, 301) and telecentric ends (102, 202, 302). The main bodies (10, 20, 30) comprise first filter nets (11, 21, 31) located between the proximal ends (101, 201, 301) and the telecentric ends (102, 202, 302) and adjacent to the proximal ends (101, 201, 301), and a plurality of first support rods (131, 231, 331) connected to the first filter nets (11, 21, 31) and located between the first filter nets (11, 21, 31) and the telecentric ends (102, 202, 302). The first support rods (131, 231, 331) generally extend in a direction parallel to the longitudinal central axis of the filters (100, 200, 300). The ratio of the projection length of each first support rod (131, 231, 331) in the plane parallel to the longitudinal central axis of the filters (100, 200, 300) and the natural length of the filters (100, 200, 300) is greater than or equal to 1/11 and less than or equal to 3/4. After being naturally released, the filters (100, 200, 300) can be stably and reliably placed in a blood vessel and are not prone to tilting, and the removal of the filters (100, 200, 300) causes a relatively small amount of damage to the inner wall of the blood vessel.
(FR) La présente invention concerne des filtres (100, 200, 300), comprenant des corps principaux (10, 20, 30) avec des extrémités proximales (101, 201, 301) et des extrémités télécentriques (102, 202, 302). Les corps principaux (10, 20, 30) comprennent des premières grilles de filtre (11, 21, 31) situées entre les extrémités proximales (101, 201, 301) et les extrémités télécentriques (102, 202, 302) et adjacentes aux extrémités proximales (101, 201, 301), une pluralité de premières tiges de support (131, 231, 331) raccordées aux premières grilles de filtre (11, 21, 31) et situées entre les premières grilles de filtre (11, 21, 31) . et les extrémités télécentriques (102, 202, 302). Les premières tiges de support (131, 231, 331) s'étendent généralement dans une direction parallèle à l'axe central longitudinal des filtres (100, 200, 300). Le rapport de la longueur de projection de chaque première tige de support (131, 231, 331) dans le plan parallèle à l'axe central longitudinal des filtres (100, 200, 300) et la longueur naturelle des filtres (100, 200, 300) est supérieur ou égal à 1/11 et inférieur ou égal à ¾. Après avoir été libérés naturellement, les filtres (100, 200, 300) peuvent être placé de façon stable et fiable dans un vaisseau sanguin et ne sont pas sujets à inclinaison, et le retrait des filtres (100, 200, 300) cause relativement peu de dommages à la paroi interne du vaisseau sanguin.
(ZH) 一种滤器(100,200,300),包括具有近心端(101,201,301)和远心端(102,202,302)的主体部(10,20,30),主体部(10,20,30)包括位于近心端(101,201,301)及远心端(102,202,302)之间且邻近近心端(101,201,301)的第一过滤网(11,21,31),及多个分别与第一过滤网(11,21,31)相连且皆位于第一过滤网(11,21,31)与远心端(102,202,302)之间的第一支撑杆(131,231,331);第一支撑杆(131,231,331)大致沿平行于滤器(100,200,300)的纵向中心轴的方向延伸,每个第一支撑杆(131,231,331)在平行于滤器(100,200,300)的纵向中心轴的平面内的投影长度与滤器(100,200,300)的自然长度的比值大于或等于1/11,且小于或等于3/4。滤器(100,200,300)自然释放后,可以稳定地、可靠地放置于血管中,不易发生倾斜,且滤器(100,200,300)取出对血管内壁的损伤较小。
