A vascular stent conveying system comprises a housing (110, 120), an outer sleeve (200), a cleaning tube (300), an inner tube (800), and a driving assembly (400). The outer sleeve (200) is located outside the housing (110, 120) and is connected to a first end (101) of the housing (110, 120). The cleaning tube (300) is connected to a second end (102) of the housing (110, 120), a first end (301) of the cleaning tube (300) is located in the housing (110, 120), and a second end (302) of the cleaning tube (300) extends out of the housing (110, 120). A part of the inner tube (800) is located in the housing (110, 120), a first end of the inner tube (800) extends into the outer sleeve (200), and a second end of the inner tube (800) extends from the first end (301) of the cleaning tube (300) to a tube chamber of the cleaning tube (300). A part of the driving assembly (400) is located in the housing (110, 120), and is in operation combination with the part of the inner tube (800) located in the housing (110, 120), so as to drive the inner tube (800) to allow the inner tube (800) to move along an axial direction in the outer sleeve (200) and the cleaning tube (300). An end portion of the second end of the inner tube (800) is arranged in a way for preventing the end portion of the second end of the inner tube (800) from scraping the inner wall of the tube chamber of the cleaning tube (300).La présente invention concerne un système de transport d'endoprothèse vasculaire comprenant un boîtier (110 120), un manchon externe (200), un tube de nettoyage (300), un tube interne (800) et un ensemble d'entraînement (400).
