摘要
An interventional medical device delivery system comprises a loader provided with a loading tube, a delivery sheath, a dilator, a pushing component, and a hemostasis valve. The loading tube or the delivery sheath is provided with a position-limiting locking connector. An appropriate-rotation control mechanism for controlling a tightening degree between a distal end of the loading tube and a proximal end of the delivery sheath is disposed outside the loading tube or the delivery sheath. The proximal end of the delivery sheath and the distal end of the loading tube engage with each other in a sealed manner, and are threadingly fixed to each other by means of the position-limiting locking connector. The appropriate-rotation control mechanism rotates in one direction to appropriately tighten a thread-connection, and rotates in the opposite direction to release the thread-connection. The interventional medical device conveying system of the invention automatically determines a tightening degree.
