Description
Technical Field
The invention relates to the technical field of medical instruments, in particular to a heart valve anchoring device.
Background
Heart valve disease is a very common heart condition, with valve damage from rheumatic heat being one of the most common causes. With the aging and the increasing population, senile valvular diseases and valvular diseases caused by coronary heart disease myocardial infarction are more and more common. These valvular lesions not only endanger life safety and affect quality of life, but also bring heavy burden and pressure to families and society. The heart of a human body is divided into four heart chambers, namely a left atrium, a left ventricle, a right atrium and a right ventricle, wherein the two atria are respectively connected with the two ventricles, and the two ventricles are connected with the two main arteries. The heart valve grows between the atrium and the ventricle and between the ventricle and the aorta, and plays the role of a one-way valve to help the blood flow move in a single direction. The four valves of the body are called the mitral valve, the tricuspid valve, the aortic valve, and the pulmonary valve, respectively. These valves, if diseased, can affect the movement of blood flow, causing cardiac dysfunction, ultimately leading to heart failure.
In recent years, percutaneous transcervical mitral valve replacement can be performed for patients with mitral stenosis and regurgitation, i.e. the procedure is performed by implanting a heart valve through an interventional and minimally invasive method, so that the patients avoid the pain of an open chest operation. After the heart valve is implanted into a human heart, the heart valve needs an anchoring device to be fixed with the wall of the heart chamber so as to prevent the heart valve from falling off. The existing heart valve is fixed through a spiral anchoring needle, when the heart valve is frequently stretched, the anchoring needle is easy to fall off, and the heart valve is loosened and falls off.
