Problems solved by technology

[0009] The problems of MitraClip are as follows: Intervention from the femoral artery through a long sheath is difficult to operate and takes a long time; due to the use of a large-sized sheath during the operation, there may be residual atrial septal leakage after the operation; the mitral valve opening is changed from a single hole to a Double holes will reduce the area of ​​the mitral valve orifice; fixing the prolapsed valve and the healthy valve together may cause changes in the tension of the healthy valve cord and accelerate its degeneration

Embodiment 1

[0087] see Figure 14 , 4 , 15, Figure 14 Schematic diagram of capturing the valve leaflet after the valve repair device enters the ventricle through the apex of the heart, Figure 4 Schematic diagram for the release of the artificial chord, Figure 15 Completed schematic for artificial chordal repair.

[0088] Make a purse at the apex of the heart, perform conventional apical puncture, implant the sealing sheath 1 into the ventricle, and then inflate the air bag 6 at the head end of the sealing sheath 1 to prevent damage to the normal leaflets during the operation, and then make the sealing sheath 1 under the guidance of ultrasound. The end of the sheath 1 with the balloon 6 is close to the valve leaflet 15 to be repaired, and then the catcher 2 is used to capture the valve leaflet 15 to be repaired, and then according to Figure 4 As shown, the implantation of the artificial chord is completed. After the device is withdrawn, the length of the artificial chord is adjusted ...

Abstract

The invention discloses a valve repair device. The valve repair device comprises a sealing sheath, a catcher, a puncture needle, an artificial chordae tendineae and a handle, wherein the catcher is arranged at the far end of the sealing sheath and used for catching and fixing a valve cusp, the puncture needle is arranged in the sealing sheath and used for puncturing the caught valve cusp of the catcher, the artificial chordae tendineae punctures into the valve along with the puncture needle and is used for repairing the valve, and the handle is arranged at the near end of the sealing sheath and used for operating the valve repair device.

Description

technical field [0001] The present invention relates to a medical device, more specifically to a transapical valve repair device. Background technique [0002] The normal human heart has four chambers: left ventricle, left atrium, right ventricle, and right atrium. The left ventricle communicates with the left atrium, and the right ventricle communicates with the right atrium. The heart has four valves, the valve between the left ventricle and the left atrium is the mitral valve, the valve between the right ventricle and the right atrium is the tricuspid valve, the valve between the left ventricle and the aorta is the aortic valve, and the valve between the right ventricle and the pulmonary artery The valve is the pulmonary valve. [0003] The mitral and three-chamber valves generally have 2-3 leaflets, the end of which is the valve annulus, and the leaflets are fixed to the papillary muscle by the chordae. [0004] A normal valve can ensure the smooth flow of blood in on...
