Problems solved by technology

[0002] Mitral valve regurgitation is the most common mitral valve disease. The treatment methods for patients with mitral valve regurgitation usually include repair and replacement. Repair is the first choice and the best way, but in fact many dysfunctional valves use Repair means can not achieve the therapeutic effect, in this case, mitral valve replacement (MVR) is required
During the operation, the transapical path is usually taken, and the turning of the mitral v

Abstract

The invention provides an integrated surgical mitral valve replacement system which is characterized in that the integrated surgical mitral valve replacement system comprises an outer layer support and at least two surgical mitral valves arranged in the outer layer support; the outer layer support is a saddle-shaped structure support with a D-shaped section, and the edge of the outer layer support is coated with a soft material layer; and each surgical mitral valve comprises a valve seat, a valve frame and at least three biological tissue valve leaflets attached to the valve frame, and the valve seat, the valve leaflets and the valve frame are connected through a fabric layer wrapping the valve frame. According to the integrated surgical mitral valve replacement system, the ventricular outflow tract can be prevented from being blocked, meanwhile, the risk of winding with chordae tendineae is reduced, opening and closing are not interfered by factors except for blood flow, the requirements of the human body can be met, and a better treatment effect can be achieved on the whole.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to an integrated surgical mitral valve replacement system. Background technique [0002] Mitral valve regurgitation is the most common mitral valve disease. The treatment methods for patients with mitral valve regurgitation usually include repair and replacement. Repair is the first choice and the best way, but in fact many dysfunctional valves use Repair means can not achieve the therapeutic effect, then you need to perform mitral valve replacement (MVR). [0003] CN109009569A discloses an artificial valve interventional replacement device for mitral valve insufficiency, including a support body and artificial valve leaflets, the lower edge of the support body is a cone structure with a "D" cross section, and several blocking blocks are arranged in the support body The lower edge is connected with several artificial valve leaflets, which can move with the patie...
