[0002] Vascular bypass is the common surgical method for treating moyamoya disease, cerebral vascular occlusion and complex aneurysm in clinic, which is completed by accurately matching the two opposite anastomosis openings of the lumen and suturing. The anastomosis blood vessel is usually a small artery with a diameter of about 1mm. In the blocked state, the blood vessel lumen collapses, and technical errors such as mis-suturing of the opposite wall and non-full-layer suturing are prone to occur. These errors can cause anastomosis stenosis or thrombosis.
[0003] Currently, in the vascular bypass surgery, a blood vessel anastomosis support dilator is used to assist suturing. The blood vessel anastomosis support dilator supports and dilates the blood vessel or lumen to establish a clear anastomosis platform for the operator, which is beneficial to the precise anastomosis of the operator, shortens the anastomosis time, and can avoid iatrogenic damage during surgery to reduce the probability of technical errors. However, the existing blood vessel anastomosis support dilator can only support the proximal end and the distal end of the recipient blood vessel for basic anastomosis. When facing a three-way lumen, the donor blood vessel cannot be supported, the end side anastomosis is difficult, and the suturing is inconvenient, which still has a high probability of technical errors.
