Problems solved by technology
However, when the mitral valve is diseased, it may be difficult to completely close the left ventricle when it contracts, causing the left atrium to receive a large amount of backflow blood, which may lead to a sharp increase in the pressure of the left atrium and pulmonary veins, and the diastolic volume of the left ventricle. The load increases, and further leads to a series of pathological changes such as left ventricular enlargement and pulmonary hypertension, and finally leads to clinical manifestations such as heart failure and arrhythmia, which can be life-threatening in severe cases

The present invention discloses a mitral valve repair device. The mitral valve repair device comprises a tissue clamping device and a control handle; the tissue clamping device comprises outer clamping arms and inner clamping arms; the control handle comprises an outer clamping arm control mechanism and an inner clamping arm control mechanism, the outer clamping arm control mechanism is used for controlling the outer clamping arms to open and close, and the inner clamping arm control mechanism is used for controlling the inner clamping arms to open and close relative to the outer clamping arms; and the control handle is used for conveying the tissue clamping device to a mitral valve via a left auricle and a left atrium and controlling the outer clamping arms and inner clamping arms to openand close to enable the mitral valve to be clamped between the outer clamping arms and the inner clamping arms.
Description
technical field [0001] The present application relates to the field of medical equipment, in particular to a mitral valve repair equipment. Background technique [0002] A valve is a membrane-like structure that can open and close in the organs of humans or some animals. For example, each human heart has four valves, namely the aortic valve, pulmonary valve, mitral valve and tricuspid valve. Taking the mitral valve as an example, the mitral valve is located between the left atrium and the left ventricle. When the left ventricle contracts, the mitral valve acts as a check valve to tightly close the atrioventricular opening and prevent blood from flowing backward from the left ventricle. Left atrium. However, when the mitral valve is diseased, it may be difficult to completely close the left ventricle when it contracts, causing the left atrium to receive a large amount of backflow blood, which may lead to a sharp increase in the pressure of the left atrium and pulmonary vein...
