One end of the shunt tube has a protrusion, which is inserted into the proximal end of the arterial blood vessel, and is clamped with a blocker on the side of the protrusion close to the center of the shunt tube to prevent blood from rushing the shunt tube out of the blood vessel; one end of the shunt tube has a groove for connecting a safety rope or the safety rope is directly compounded on the shunt tube to prevent misoperation during surgery, which causes the shunt tube to be rushed into the deep of the blood vessel and increase harm to the patient; both ends of the shunt tube have rounded corners to prevent damage to the blood vessel.

[0011] During vascular surgery, the blood vessels at both ends of the vascular area to be operated on are first blocked, disconnected or opened; the shunt tube is clamped with a vascular clamp to block its passage, the second connector with a protrusion at one end of the shunt tube is inserted into the blood vessel at the proximal end, and then the first connector at the other end is inserted into the opposite blood vessel, the shunt tube is clamped with a blocker, and the vascular clamp on the shunt tube is removed, so that the artery continues to supply blood to the body tissue. The utility model has a novel structure and an ingenious design. The shunt tube has a simple structure and is easy to operate. It can also form a disposable medical device with controllable quality and risk, thereby reducing surgical risks. BRIEF DESCRIPTION OF THE DRAWINGS
