Mitral valve repairing and implanting system

Abstract

The invention provides a mitral valve repairing and implanting system and relates to the technical field of medical instruments. The mitral valve repairing and implanting system comprises a connecting seat, distance adjusting mechanisms and a plurality of implanting supporting legs, wherein the two ends of each implanting supporting leg are a fixed end and a free end separately, the fixed ends are arranged on the connecting seat, all the fixed ends are annularly distributed, all the free ends are located at the same side of the connecting seat, and the free ends are used for implanting spiral nail bodies; and one distance adjusting mechanism is arranged on at least two adjacent implanting supporting legs, and the corresponding distance adjusting mechanism is used for changing the distance between adjacent two free ends. According to the mitral valve repairing and implanting system provided by the invention, the plurality of implanting supporting legs for implanting the screw nail bodies are arranged to be of a structure with one end fixed and the other end freely extending, and the distance adjusting mechanisms can be used for adjusting the distance between any two adjacent free ends, so that a mitral valve repair surgery has the effects of high efficiency and reliability in operation, and accurate, free and controllable positioning of the spiral nail bodies.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a mitral valve repair implantation system. Background technique [0002] The mitral valve is the left atrioventricular valve, which is attached to the left fibrous atrioventricular annulus and is formed by the folds of the endocardium. During ventricular contraction, the mitral valve can tightly close the atrioventricular orifice and prevent blood from flowing backward into the left atrium. When the mitral valve is damaged and there is blood regurgitation, mitral valve repair is usually performed clinically on the patient. [0003] figure 1 It is a schematic diagram of the structure of the traditional mitral valve repair implant system when it is opened; figure 2 It is a schematic diagram of the structure of the traditional mitral valve repair implant system when it is folded. Such as figure 1 , 2 As shown, the mitral valve repair implant system used in traditional...

AI Technical Summary

Problems solved by technology

[0004] However, in the traditional mitral valve repair implantation system, since each implanted leg 300 is spliced ​​and fixed one by one, they are pulled and restricted each other, so the process of screwing the distance-adjustable nut 201 has an effect on the operation efficiency of each helical nail body 400. Very low, and the controllability of the implant positioning of the screw body 400 is poor
