Embodiment Construction
[0012] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:
[0013] Such as figure 1 , figure 2 , image 3 As shown: the artificial blood vessel of the present invention is mainly composed of four parts: an ordinary artificial blood vessel part, a round corner turning transition part, a parallel blood vessel part, and a sutured edge part at the end. It is characterized in that the artificial bypass blood vessel has a rounded turning part, which can reduce the angle between the bypass blood vessel and the bypassed blood vessel to zero, so as to reduce the disturbance of blood flow at the bypass suture. By using the artificial blood vessel of the present invention for bypassing, the blood flows through the artificial common blood vessel part into the round corner transition part, and the included angle between the blood flow direction in the bypass blood vessel and the axial direction of the bypassed blo...
