摘要：
Disclosed is a lockable implant pushing device (10) and an implant delivery system (100). The implant delivery system (100) comprises the implant pushing device (10), an expansion device (20), a loading device (30), a hemostasis device (40), and an outer sheath tube (50). The pushing device (10) comprises a pushing assembly (1000) and a handle assembly (2000) connected to a proximal end of the pushing assembly (1000). The pushing assembly (1000) comprises a hollow pushing steel cable (1100), an inner core (1200) movably inserted in the pushing steel cable (1100), and a clamping member (1300) disposed at a distal end of the inner core (1200) and detachably coupled to an implant (200)； The clamping member (1300) includes at least two clamping arms (1320), and a distal end of at least one of the clamping arms (1320) is provided with a hook member (1310). The hook member (1310) extends towards a central axis of the pushing steel cable (1100) or away from the central axis of the pushing steel cable (1100). The plurality of hook members (1310) extend in different directions. The implant pushing device (10) has a reliable connection with the implant (200), thereby preventing the implant (200) from being released before reaching the designated site, and the implant(200) can be released by one-handed operation.L'invention concerne un dispositif de poussée d'implant verrouillable (10) et un système de distribution d'implant (100). Le système de pose d'implant (100) comprend le dispositif de poussée d'implant (10), un dispositif d'expansion (20), un dispositif de chargement (30), un dispositif d'hémostase (40) et un tube de gaine externe (50). Le dispositif de poussée (10) comprend un ensemble de poussée (1000) et un ensemble poignée (2000) relié à une extrémité proximale de l'ensemble de poussée (1000). L'ensemble de poussée (1000) comprend un câble d'acier de poussée creux (1100), un noyau interne (1200) inséré de façon mobile dans le câble d'acier de poussée (1100), et un é
