Abstract

The invention provides a mitral valve repair system, and relates to the technical field of medical instruments. The mitral valve repair system comprises a conveying sheath tube, a guide tube, a puncture part and a supporting piece. The supporting piece is arranged at the outlet end of the conveying sheath tube; the guide tube is arranged in the conveying sheath tube, and the puncture part is movably arranged in the guide tube; the guide tube is used for guiding the puncture part to the outlet end of the conveying sheath tube and abutting against the supporting piece, and the puncture part is used for enabling the anterior lobe and the posterior lobe of the mitral valve to be connected. Compared with a conventional clamping repair method, the mitral valve repair system has the advantages that connection repair of the anterior lobe and the posterior lobe of the mitral valve is achieved through the puncture part, and the closing stability of the mitral valve and the use long-term effect of the mitral valve repair system are greatly improved. Moreover, the puncture part can be designed to be small and light, operation is convenient, interference to the heart is reduced, and operation safety is improved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a mitral valve repair system. Background technique [0002] The mitral valve is the valve between the left atrium and the left ventricle. When the mitral valve is not closed completely, blood can flow back to the left atrium, that is, mitral valve regurgitation occurs, which will cause a series of pathological changes and clinical symptoms of the heart. Symptoms, which can lead to heart failure in severe cases. [0003] There are various types of surgery for the above conditions. Among them, the classification according to the operation method includes surgical thoracotomy and minimally invasive interventional operation, and the classification according to the valve treatment method includes mitral valve repair and valve replacement. Clinically, for patients who are elderly, have a history of thoracotomy, poor heart function, and multiple organ insufficiency, and their ...
