Mechanical suture type artificial heart valve and suture method thereof

Abstract

The invention discloses a mechanical suture type artificial heart valve and a suture method thereof. A suture valve ring (10) of an artificial heart valve takes a plastic valve ring (13) as a bracket; a concave-convex lantern ring (14) is sleeved on the plastic valve ring (13); an outer edge of the concave-convex lantern ring (14) is wrapped by a polyester ring sleeve (15); and a metal valve leaflet (12) is erected in an inner hole (K) of a metal valve ring (11) of a mechanical valve. A mechanical suture device is arranged at the front end of a tube-shaped anastomat (4); the suture valve ring (10) is arranged on the outer edge of a disk of a combined disk bottom anvil support (7); and the plastic valve ring (13) and the polyester ring sleeve (15) are sleeved on the inner edge of the disk. The preliminary suture is carried out after the combined disk bottom anvil support (7) is placed. A cutting and positioning suture method comprises the following steps of: pushing an annular tube cutter (9) to cut off a pathological mitral valve (Q) sleeved on an inner ring of the suture valve ring (10); suturing the suture valve ring (10) with a heart chamber (R) by a staple (17); taking out the combined disk bottom anvil support (7); and then sheathing the mechanical valve with the suture valve ring (10). The mechanical suture type artificial heart valve disclosed by the invention has the advantages of accuracy in positioning, favorable suture quality, high efficiency and success rate of an operation. The pains of patients are alleviated.

Description

technical field [0001] The invention relates to a device and a method for treating heart mitral valve disease, in particular to an artificial heart valve and a use method thereof. Background technique [0002] At present, the common method of medical clinical treatment of heart mitral valve disease at home and abroad is mitral valve replacement (that is, replacement of artificial heart valve). A heart valve is inserted into the heart and stitched by hand. In the application process, an extracorporeal circulation system is first established to divert the hypoxic venous blood returning to the heart into the artificial heart-lung machine. The pulmonary oxygenation of the artificial heart-lung machine turns the venous blood into high-oxygen arterial blood, and then the artificial heart turns the arterial blood The blood is pumped into the aorta, the heart is evacuated, and there is no blood in the heart, and then the heart is opened to perform heart surgery while maintaining b...

AI Technical Summary

Problems solved by technology

Although this surgical method can effectively perform heart mitral valve replacement, it has the following disadvantages: the resection of the heart valve is not neat, the needle distance and edge distance of the manual suture are uneven, the force on the suture edge is uneven, and the suture time is long: once the artificial suture Heart valve failure, the second valve replacement operation is complicated, increasing the pain and economic burden of patients
