Abstract

The invention relates to an artery shunt suppository. The artery shunt suppository comprises a main body tube, a retractable tube and a pull wire; the main body tube is a bendable elastic tube; the retractable pipe is provided with a guide section and a threading hole; the guide section comprises a flaring end and a narrow end which are different in calibre size; furthermore, the flaring end with the relatively large calibre size faces the main body tube; the threading hole penetrates through the retractable tube in the axial direction and is communicated with the guide section; one end of the pull wire is connected with the tube body position of the main body tube; and the other end of the pull wire penetrates through the guide section and the threading hole. According to the artery shunt suppository, the operation of implanting a target blood vessel can be quickly and conveniently completed; and the implanting efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an arterial shunt embolus. Background technique [0002] Coronary artery shunt plugs are commonly used in clinical coronary artery bypass grafting. By incision at the distal end of the stenotic coronary artery, arterial shunt plugs are inserted, and the diversion effect of the arterial shunt plugs is used to ensure blood supply to the distal end and prevent vascular incision. Bleeding to facilitate anastomosis. [0003] At present, imported arterial shunt plugs are mainly used in off-pump coronary artery bypass grafting, such as Clearview produced by Medtronic and Flo-Thru produced by Sonos. The main tubes of these two arterial shunt plugs are The soft tube can be pulled out conveniently after the anastomosis is completed, and its end adopts a hard structure with a diameter slightly larger than the inner diameter of the blood vessel, so that it can be inserted into the b...
