    • Provided is a vascular anastomosis device for favorably anastomosing two blood vessels with different diameters. T he vascular anastomosis device comprises two rings with pins 21 made of a flexible material and an openable ring holder 2 2, which is made of a pair of components and detachably hold s the rings with pins 21, the ring holder 22 has a means for deforming the rings with pins, the end portion of the large-diameter blood vessel is inserted through a ring 21 and the vascular wall is extended outward 90 degrees and impaled on the pins, the end portion of the small-diameter blood vessel is inserted through the other ring 21, an incision is made i n a longitudinal direction from the end surface of the small -diameter blood vessel, the two rings 21 are elliptically de formed into a same elliptical shape by the means for deformi ng the rings so that the minor axis agrees with the diameter of the small-diameter blood vessel, the small-diameter blood vessel is elliptically opened and the vascular wall is exte nded outward 90 degrees and impaled on the pins, and the two rings 21 are joined together by allowing the pins provided o n the ring in one component to stick into the ring in the oth er component.
    • 提供一种用于有利地吻合两个不同直径的血管的血管吻合装置。 血管吻合装置包括具有由柔性材料制成的销21的两个环和由一对部件制成并且可拆卸地保持环的销的可打开的环保持器2 2,环保持器22具有用于 使用针使环变形,大直径血管的端部穿过环21插入,血管壁向外延伸90度并刺入销,小直径血管的端部插入通过 另一个环21,从小直径血管的端面沿长度方向形成切口,通过使环变形的装置将两个环21椭圆形地形成为相同的椭圆形状,使得短轴 与小直径血管的直径一致,小直径血管椭圆形开口,血管壁向外偏出90度并刺入销,两个环21连接到 通过允许在一个组件中的环上提供的销钉粘附到第二组件中的环中。
