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 invention provides a clamping instrument which mainly comprises a base, an anchoring structure, a clamping structure and a combined structure, the clamping structure is connected with the base and can pivot relative to the base to form different clamping angles, the combined structure is connected with the anchoring structure and the base, the anchoring structure is used for anchoring target tissue, the clamping structure is used for clamping the target tissue anchored on the anchoring structure, and the composite structure is used for providing axial positioning and circumferential rotation of the anchoring structure relative to the base. Therefore, the clamping stability of the clamping instrument can be improved, and the tapping depth of the target tissue can be accurately controlled, so that stable and consistent connection force is maintained between the anchoring structure and the target tissue.

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...
