Abstract
(EN)
Provided is a stent conveying device (100) for releasing a stent (200) into a vessel. The stent conveying device (100) comprises: a fixing assembly (1) comprising a fixing member (11) and a limiting member (12), one end of the limiting member (12) penetrating through the stent (200) and abutting against the fixing member (11) so as to lock the stent (200); and a release assembly (2) comprising a movable member (21) and a fastening member (22) connected to the movable member (21), wherein the movable member (21) is connected to the other end of the limiting member (12), and the fastening member (22) is in sliding connection with the movable member (21); when the fastening member (22) is in a first position, the movable member (21) is fixed relative to the fixing member (11) under the limitation of the fastening member (22); and when the fastening member (22) slides to a second position, the movable member (21) can drive the limiting member (12) to move away from the fixing member (11) so as to release the stent (200). Provided is the stent conveying device (100) capable of effectively releasing the stent (200) to a position of diseased vessel.

L'invention concerne un dispositif de transport (100) de stent pour libérer un stent (200) dans un vaisseau. Le dispositif de transport (100) de stent comprend : un ensemble de fixation (1) comprenant un élément de fixation (11) et un élément de limitation (12), une extrémité de l'élément de limitation (12) pénétrant à travers le stent (200) et venant en butée contre l'élément de fixation (11) de manière à verrouiller le stent (200) ; et un ensemble de libération (2) comprenant un élément mobile (21) et un élément de fixation (22) relié à l'élément mobile (21), l'élément mobile (21) étant relié à l'autre extrémité de l'élément de limitation (12), et l'élément de fixation (22) étant en liaison coulissante avec l'élément mobile (21) ; lorsque l'élément de fixation (22) est dans une première position, l'élément mobile (21) est fixé par rapport à l'élément de fixation (11) sous la limitation de l'élément de fixation (22) ; et lorsque l'élément de fixation (22) coulisse vers une seconde position, l'élément mobile (21) peut amener l'élément de limitation (12) à s'éloigner de l'élément de fixation (11) de façon à libérer le stent (200). L'invention concerne le dispositif de transport (100) de stent capable de libérer efficacement le stent (200) vers une position de vaisseau malade.
