摘　　要：目的 :研究一种新的激光吻合离断血管的方法。方法 :利用光路转换装置使激光束呈线状光束照射在特殊反射弧面 ,当离断血管特定位置时 ,激光环形、均匀地照射在血管圆周。选择生物可溶性材料制作血管内支撑物 ,以在吻合过程中保持血管形状并保护血管内膜。结果 :利用激光环形血管吻合系统吻合血管省时省力 ,吻合均匀。血管内支撑物材料无毒。结论 :激光环形血管吻合方法可行 ,组织恢复快并保证了吻合口周围焊接均匀 ,对血管的功能恢复具有良好作用。AIM:To develop a new CO 2 laser blood vessel and nerve circular welding system which can make an circle instant and uniformed anastomosis on the of blood vessel and nerve .METHODS:①Useing ray transition device make the laser beam homogeneous on the circle of blood vessel and nerve. ②Using dissoluble material which could be used as a backstop used in vascular to protect the wall and the shape of blood vessel. RESULTS: Use this method is more efficiency than the traditional welding method. The anastomosis tissue is recover fast and the wounded is homogeneous. The material used as a underprop is innocuity. CONCLUSION: The blood vessel and nerve circular welding method is doing well.It is good for the laser blood vessel and nerve recover.
