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.
