Title
(EN) ADJUSTABLE CURVED SHEATH TUBE AND STENT DELIVERY DEVICE
(FR) TUBE DE GAINE INCURVÉ RÉGLABLE ET DISPOSITIF DE POSE DE STENT
(ZH) 可调弯鞘管及支架输送装置
Abstract
(EN)
An adjustable curved sheath tube (4), which is used for delivering a stent (200) into a blood vessel and which comprises: a bendable tube body (41) and a pull wire (42); an end of the pull wire (42) is fixedly connected to an end of the bendable tube body (41), while the other end of the pull wire (42) passes through the bendable tube body (41) and penetrates into the bendable tube body (41) until same passes through the other end of the bendable tube body (41); when the other end of the pull wire (42) is pulled, the pull wire (42) drives an end of the bendable tube body (41) to move close to the other end of the pull wire (42) so as to bend the bendable tube body (41). The present invention also relates to a stent delivery device (100) comprising an adjustable curved sheath tube (4), which may effectively release a stent (200) at a diseased blood vessel.
(FR)
L'invention concerne un tube de gaine incurvé réglable (4), qui est utilisé pour poser un stent (200) dans un vaisseau sanguin et qui comprend : un corps de tube pliable (41) et un fil de traction (42) ; une extrémité du fil de traction (42) est reliée de manière fixe à une extrémité du corps de tube pliable (41), tandis que l'autre extrémité du fil de traction (42) passe à travers le corps de tube pliable (41) et pénètre dans le corps de tube pliable (41) jusqu'à ce que celle-ci passe à travers l'autre extrémité du corps de tube pliable (41) ; lorsque l'autre extrémité du fil de traction (42) est tirée, le fil de traction (42) entraîne une extrémité du corps de tube pliable (41) à se déplacer à proximité de l'autre extrémité du fil de traction (42) de façon à plier le corps de tube pliable (41). La présente invention concerne également un dispositif de pose de stent (100) comprenant un tube de gaine incurvé réglable (4), qui peut libérer efficacement un stent (200) au niveau d'un vaisseau sanguin malade.
(ZH)
一种可调弯鞘管(4),用于将支架(200)输送至血管内,包括:可弯曲管体(41)及牵引线(42),牵引线(42)的一端固定连接可弯曲管体(41)的一端,牵引线(42)的另一端穿出可弯曲管体(41),并穿入可弯曲管体(41)内直至穿出可弯曲管体(41)的另一端,当拉动牵引线(42)的另一端时,牵引线(42)带动可弯曲管体(41)的一端靠近牵引线(42)的另一端,以使可弯曲管体(41)弯曲。还涉及一种包括可调弯鞘管(4)的支架输送装置(100),能够有效地将支架(200)释放于病变血管处。
