The traction mechanism (120) includes an anchor ring (121) and a traction wire (122). The anchor ring (121) is coaxially embedded in a distal elastic segment (111) of the tube body (110). The traction wire (122) is arranged in a side wall of the tube body (110), and extends along the axial direction of the tube body (110). The traction wire (122) includes a first segment and a second segment connected to each other, wherein the first segment is connected to the fixing and connecting mechanism (130) near a proximal end of the tube body (110), and the second segment hooks the anchor ring (121).
