Tricuspid valvuloplasty ring

Abstract

The invention relates to a tricuspid valvuloplasty ring. The tricuspid valvuloplasty ring comprises a ring body with an opening; the ring body is continuously and successively composed of a front ringsegment which is suitable for fixing the anterior lobe as well as an area adjacent to the anterior lobe, a rear ring segment which is suitable for fixing the posterior lobe as well as an area adjacent to the posterior lobe, and a spacer ring segment which is suitable for fixing the septal cusp as well as an area adjacent to the septal cusp; one thirds of the front ring segment close to an openingend, one thirds of the rear ring segment close to the spacer ring segment and the spacer ring segment are rigid molded areas which are difficult to deform; and one thirds of the front ring segment close to the rear ring segment and one thirds of the rear ring segment close to the front ring segment are deformable plastic molding areas. The tricuspid valvuloplasty ring has the following beneficialeffects: the tricuspid valvuloplasty ring is capable of reducing distance between the anterior tricuspid annulus and the septal annulus, so that targeted settings are available for conditions with significant right ventricular dilation, obvious displacement of papillary muscle and leaflet bondage; and thus, area and height of valve leaf involution can be effectively increased under the premise ofensuring enough opening area, thereby providing effective and long-lasting molding effects.

Description

technical field [0001] The invention relates to medical device technology, in particular to a tricuspid annulus forming ring. Background technique [0002] The normal human heart valves are located between the atrium and ventricle and between the ventricle and the aorta. The four valves are the mitral valve, aortic valve, tricuspid valve and pulmonary valve. They function as one-way valves to help blood flow in one direction. cycle. For the tricuspid valve, non-oxygenated blood enters the right ventricle from the right atrium through the open tricuspid valve orifice when the right ventricle is in diastole, and the tricuspid valve closes when the right ventricle contracts to prevent backflow of blood to the right atrium. [0003] figure 1 It is a schematic diagram of the closed state of the normal tricuspid valve viewed from the right atrium. Its leaflets include the anterior leaflet 101, the posterior leaflet 102 and the septal leaflet 103 with the largest area, and also i...

Problems solved by technology

[0012] The purpose of the present invention is to overcome the deficiencies in the prior art, to solve the problem of long course of disease, combined with significant right ventricle enlargement and papillary muscle displacement, forming severe type IIIb tricuspid regurgitation by using the existing mainstream oval rigid tricuspid The annuloplasty ring cannot achieve effective valve leaflet coaptation and satisfactory tricuspid annuloplasty effect
