Problems solved by technology

Among the surgical methods, the typical thoracotomy is highly invasive and requires the establishment of extracorporeal circulation, which has a high incidence of complications and risk of infection. As a result, many patients cannot bear the huge surgical risk and can only wait for death helplessly.
[0005] At present, there are few minimally invasive transcatheter products approved in China for the treatment of secondary and tricuspid regurgitation. These products need to change the structure of the heart during the healing process. Brings a lot of pressure and incompatibility to cardiac surgery

Abstract

The application provides a clamping device, which mainly includes a clamping base, a driving base, a clamping structure with different clamping angles formed according to the distance between the clamping base and the driving base, and a fine adjustment member, wherein the fine adjustment can be made by The parts and the driving seat are dissociated or connected to each other, so that the driving seat can move quickly or step by step relative to the clamping seat, so as to achieve the purpose of quickly adjusting or finely adjusting the clamping angle of the clamping structure. Accordingly, the application not only It can improve the operation convenience of the clamping instrument, and can provide precise clamping force control effect.

Description

technical field [0001] The embodiments of the present application relate to the technical field of medical devices, in particular to a clamping device. Background technique [0002] Mitral valve, tricuspid valve, aortic valve, pulmonary valve and other common diseases are valvular insufficiency. Taking the mitral valve as an example, during systole, part of the blood of the left ventricle flows to the left atrium through the insufficient mitral valve orifice. reflux. The left atrium receives blood from the left ventricular regurgitation and blood from the pulmonary vein at the same time, and the blood volume and pressure of the left atrium increase significantly, resulting in left atrial hypertrophy. [0003] During the diastolic period, more blood flows from the left atrium to the left ventricle, causing the left ventricle to hypertrophy due to the strengthening of contraction. After the compensation period progresses to the decompensation period, heart failure occurs in b...
