Abstract

The invention relates to an implant, a transcatheter wire locking device and a wire locking method.The implant comprises a shell assembly and a wire winding assembly installed in the shell assembly, a gear assembly is arranged in the wire winding assembly and comprises a single-face gear, a double-face gear and a fixed gear, the single-face gear and the double-face gear form first one-way rotation, and the single-face gear and the double-face gear form second one-way rotation; the fixed gear and the double-sided gear form second one-way rotation, and the rotation directions of the two are opposite; the gear assembly is in sliding connection with the winding assembly through a sliding structure, so that the far end of the winding assembly reciprocates between the single-face gear and the double-face gear. Therefore, after the suture is locked, if it is observed that the current winding degree is too large, the far end of the winding assembly can be driven to slide to the single-face gear, and therefore the current winding degree is adjusted to be small; and then the far end of the winding assembly is driven to slide to the double-sided gear, so that the current winding degree is locked. Therefore, by adopting the design of the scheme, the winding degree can be adjusted in real time after the sewing thread is locked.

Description

technical field [0001] The present application belongs to the technical field of medical devices, and in particular, relates to an implant, a transcatheter thread locking device and a thread locking method. Background technique [0002] The heart consists of four chambers: the left atrium, the left ventricle, the right atrium, and the right ventricle. There are valves (atrioventricular valves) between the atria and the ventricles. These valves allow blood to flow only from the atrium to the ventricle, but not back. Due to various pathological reasons, the human heart will have congenital heart disease, cardiomyopathy, mitral valve disease, tricuspid valve disease, coronary heart disease and other heart diseases, chest pain, cough, chest tightness, edema, palpitations, fatigue, shortness of breath, breathing Difficulty and other clinical manifestations. [0003] For heart valve disease, drug therapy or surgery is usually used for treatment. Drug therapy is difficult to effec...
