Problems solved by technology

However, due to the large surface roughness of the silicone layer and the polyester cloth tube, the friction force of the polyester cloth tube is relatively large when it is sleeved on the silica gel layer, and the polyester cloth tube cannot be spread evenly on the surface of the silicone layer, which makes blood flow easier. Formation of thrombus on the surface of polyester cloth tubing

Embodiment Construction

[0049] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0050] It should be noted that when two elements are called "connected", it may mean that the two elements are directly connected, or it may mean that the two elements are connected through an intermediate element.

[0051]The invention provides a method for preparing an annuloplasty ring, which is used for repairing damaged heart valve shapes, such as correcting enlarged valve rings, valve prolapse and other diseases. The heart valves include valves such as mitral valve, tricuspid valve, aortic valve and pulmonary valve. In the present invention, the preparation method of the valvuloplasty ring o...

Abstract

The invention relates to a method for preparing an annuloplasty ring, which comprises using a clamp to set a suture layer on a metal piece covered with a silicone layer; the clamp includes a guide section and a main section, the guide section is in the shape of a cone, and the main section is in the shape of a hollow tube , the main body section is arranged at the larger diameter end of the guide section, and the inner size of the main body section is slightly larger than the outer peripheral size of the silicone layer, so that the silicone layer can be inserted into the inner cavity of the main body section. By adopting the method for preparing an annuloplasty ring of the present invention, the suture layer can be evenly sleeved on the surface of the silica gel layer, preventing the suture layer from forming wrinkles on the surface of the silica gel layer, and reducing the possibility of thrombus formation on the surface of the suture layer.

Description

technical field [0001] The invention relates to the technical field of interventional medical devices, in particular to a method for preparing an annuloplasty ring used for heart valve repair. Background technique [0002] The human heart has four heart valves: the mitral, tricuspid, aortic, and pulmonary valves. The mitral valve, for example, is a bilobed structure of connective tissue located between and separating the left atrium and left ventricle, consisting of an annulus, an anterior leaflet connected to the anterior segment of the annulus, and a connecting to the posterior leaflet of the posterior segment of the annulus. The mitral valve acts as a one-way valve. During a cardiac cycle, when the left atrium contracts, the mitral valve opens and blood flows from the left atrium to the left ventricle; when the left ventricle contracts, the mitral valve closes and blood flows from The left ventricle pumps the whole body. [0003] When there is a disease of the mitral v...
