Problems solved by technology

[0003] Mitral valvuloplasty is a technical and skillful operation that is difficult to master in repairing the valve. During the surgical repair of valve leaflet prolapse, chordal tendon rupture, and leaflet perforation, the operation time is long, and the effect of the repair is difficult to accurately grasp
[0006] At present, the plastic rings widely used in cardiac surgery have only the effect of ring shrinkage. If the effect of trimming the valve leaflets and chordae is not good, the correction of mitral valve insufficiency will be difficult to achieve.

Embodiment 1

[0024] Such as figure 1 As shown, the mesh-type mitral annuloplasty ring is provided with a ring body 1 , a soft material 2 and a mesh wire 3 . The mesh cable 3 adopts 3-Oproline surgical thread, and the soft material 2 on the corresponding surface of the ring body 1 is connected in series to form a mesh-type mitral annuloplasty ring whose shape and size are similar to those of the mitral valve of the human heart.

[0025] During the operation, the mesh-type mitral annuloplasty ring was fixed on the ring opening of the left atrium and ventricle by the operator with interrupted sutures. When mitral regurgitation is caused by valve leaflet prolapse and rupture of the subvalvular chordae, there is no need to repair the prolapsed valve leaflet and the ruptured subvalvular chordae, only the "mesh" mitral annuloplasty ring is fixed with interrupted sutures On the ring orifice of the mitral valve, the "net" in the ring can block the valve leaflet from overextending to the left atriu...

Embodiment 2

[0027] Such as figure 2 As shown, the mesh-type mitral annuloplasty ring is provided with a ring body 1 , a soft material 2 and a mesh wire 3 . The mesh cable 3 adopts 2-Oproline surgical thread, and the soft material 2 on the corresponding surface of the ring body 1 is connected in series to form a mesh-type mitral annuloplasty ring whose shape and size are similar to those of the mitral valve of the human heart.

[0028] During the operation, the mesh-type mitral annuloplasty ring is fixed on the ring opening of the left atrium and ventricle by intermittent or continuous suture method. When the mitral valve leaflets are perforated and cause mitral valve insufficiency, as long as the leaflets are repaired, the "net" in the ring can block the leaflets from overextending to the left atrium, causing the mitral valve to close and achieve the purpose of correction.

Abstract

The invention discloses a mesh type mitral valvuloplasty ring, which comprises a ring body and flexible materials and is characterized in that 3-Oproline network cables are arranged on a ring body and are connected in series on the flexile materials on the opposite faces of the ring body to constitute the mesh type bicuspidal valve forming ring. The mesh type mitral valvuloplasty ring is simple in structure, an operation method is concise and is easy to master, an surgical operation is simplified, and the mesh type mitral valvuloplasty ring is mainly applied to heart mitral valvuloplasty for mitral insufficiency caused by mitral prolapse, valve perforation and valve chordae tendineae fracture, so that the purpose of treating the mitral valvuloplasty is achieved.

Description

technical field [0001] The present invention relates to the field of medical devices, in particular to a device for cardiac surgery, more specifically, to a device for mitral valve leaflet prolapse, valve leaflet perforation, subvalvular chordae rupture Mesh mitral annuloplasty ring for mitral valvuloplasty in hearts with mitral regurgitation. Background technique [0002] The human heart has the function of a pump. The valves of the heart are composed of thin and tough membranous tissue. The valves open and close with the contraction and relaxation of the heart. The mitral valve is the "gate" of the fibrous tissue structure of the serosa on the left atrium and ventricle. The mitral valve closes to the left atrium during systole and opens to the left ventricle during diastole. The heart of a normal person beats about 100,000 times a day, and the valve opens and closes 100,000 times a day. Second-rate. Therefore, the valves of the heart must remain flexible and tense throug...
