Disclosed in the present application is a transporting and releasing device for medical intervention instruments, which includes an outer sheath pipe, a middle pipe and an inner pipe, wherein the inner pipe, the middle pipe and the outer sheath pipe are successively distributed from inside to outside a through hole is provided on the wall of the outer sheath pipe, a slot is provided on the middle pipe, and a side pipe is provided on the inner pipe, with the side pipe passing through the slot on the middle pipe and being fixed to the through hole on the outer sheath pipe and the side pipe communicating with the through hole. During the use of the transporting and releasing device for medical intervention instruments, after a guide wire enters from a distal end of the inner pipe, the guide wire can not only pass through and exit from the proximal end of the inner pipe but also pass through and exit from the side pipe. Therefore, it not only has the advantages of coaxial transporting and releasing devices, but also has the advantages of fast switch transporting and releasing devices, and it can be switched over quickly between these two modes according to the requirements of the actual situation, which saves surgery time and improves the surgery success rate at the same time.La présente invention porte sur un dispositif de transport et de libération pour des instruments dintervention médicale, lequel dispositif de transport et de libération comprend un tuyau de gaine externe, un tuyau intermédiaire et un tuyau interne, le tuyau interne, le tuyau intermédiaire et le tuyau de gaine externe étant distribués successivement de lintérieur à lextérieur un trou traversant est prévu sur la paroi du tuyau de gaine externe, une fente est prévue sur le tuyau intermédiaire, et un tuyau latéral est disposé sur le tuyau interne, le tuyau latéral passant à travers la fente sur le tuyau intermédiaire et étant fixé au trou traversant sur le tuyau de gaine externe et le tuyau latéral com
