Abstract
A conveyor and a conveyor system are provided. The conveyor comprises a lumen assembly and a self-locking mechanism connected to the lumen assembly, wherein the lumen assembly comprises an inner core tube, a recovery sheath movably surrounding the inner core tube, and an outer sheath movably surrounding the recovery sheath; the self-locking mechanism is connected to the recovery sheath; and the outer sheath can move relative to the inner core tube in an axial direction of the conveyor. The self-locking mechanism has a self-locked state and an unlocked state, wherein when the self-locking mechanism is in the unlocked state, the recovery sheath can move relative to the inner core tube in the axial direction of the conveyor; and when the self-locking mechanism is in the self-locked state, the recovery sheath maintains stationary relative to the inner core tube.
