A support ring for aortic anastomosis including an aortic graft and a support ring is provided. Support rings are disposed at both ends of the artificial blood vessel and sutured with the graft. The support ring is arc-shaped, a surface of the support ring is provided with a plurality of elliptical first through holes, and an inner circumference of the first through hole is provided with a first chamfer. The device is used for suturing blood vessels of the ascending aorta and the aortic arch and so on. The support ring is in the graft, the graft is in the aorta, and finally they are tied and fixed on the outside of the aorta by a bandage. After the anastomosis, a curvature of a curved aorta itself can be formed and a blood leakage can be effectively avoided, and the anastomosis time is significantly reduced.本發明公開了主動脈吻合用支撐環，包括人造血管和支撐環，所述支撐環設於所述人造血管的兩端並與所述人造血管相縫合，所述支撐環呈弧形，所述支撐環的表面設有若干橢圓形的第一通孔，所述第一通孔的內周設有一圈第一倒角，本裝置用於對升主動脈、主動脈弓等部位置進行血管的縫合，支撐環在人工血管內，人工血管在主動脈內，最後在主動脈外面以綁帶將三者捆紮固定，吻合後能形成主動脈本身彎曲的弧度並且能夠有效避免漏血情況發生，顯著減少吻合時間。
