Problems solved by technology

However, when the mitral valve is diseased, it may be difficult for the mitral valve to close completely when the left ventricle 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 left Increased ventricular diastolic volume load, and further lead to a series of pathological changes such as left ventricular enlargement and pulmonary hypertension, and eventually lead to clinical manifestations such as heart failure and arrhythmia, which can be life-threatening in severe cases

Abstract

The invention discloses a tissue clamping device with a locking mechanism. The tissue clamping device comprises a clamp body, a first connecting piece, a second connecting piece and the locking mechanism. Wherein the clamp main body is connected between the first connecting piece and the second connecting piece, and the clamp main body can be driven to be opened or closed by the relative movementof the first connecting piece and the second connecting piece; the locking mechanism comprises a locking pipe, one end of the locking pipe is fixedly connected with the second connecting piece, a locking fin is arranged on the outer wall of the locking pipe, and the locking fin can limit the opening of the clamp main body.

Description

technical field [0001] The present application relates to the field of medical supplies, in particular to a tissue clamping device with a locking mechanism. Background technique [0002] In the surgical repair of body tissue, it is usually necessary to clamp and fix the tissue by means of a tissue clamping device. Take the treatment of mitral valve regurgitation, a relatively common heart disease, 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 close tightly. The atrioventricular orifice prevents reverse flow of blood from the left ventricle into the left atrium. However, when the mitral valve is diseased, it may be difficult for the mitral valve to close completely when the left ventricle 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...
