The invention discloses a magnetic device applicable to
anastomosis of large vessels. Two elliptic-cylinder-shaped anastomosing rings which correspond to the
pipe diameter of the large vessels to be anastomosed and contain permanent magnets are utilized to finish
anastomosis of the vessels with different
pipe diameters; the opposite surfaces of two permanent
magnet anastomosing rings are smooth and polished, so that the endangiums of the vessels are neatly aligned, and further the defects of narrow anastomosing ports, blood leakage, and various complications such as
massive haemorrhage, local tissue
granuloma and pseudoartery formation and the like due to slipping of ligatures caused by manual suture for
anastomosis are avoided; as the anastomosing rings are designed to be elliptic-cylinder-shaped, clamping and fixing with surgical instruments in
surgery are convenient, and the magnetic device is very beneficial to anastomosis operation of the large vessels at deep parts of the
body cavity; and the time of utilizing the anastomat to carry out anastomosis on the large vessels is more than five times shorter than that of manual anastomosis, so that the condition that the blood of tissues and organs are blocked for long time so as to cause ischemic operation of the organs or congestion and
edema and further cause dysfunction of the organs. In addition, the end surface adopts conical
titanium alloy needles and corresponding conical small holes so as to be beneficial to tight alignment of the anastomosing ports in
surgery.
