Cardiac valve repair system

Abstract

The invention discloses a cardiac valve repair system. The system comprises at least two suture lines, a suture line implanting device and a suture line knotting device, wherein the suture line implanting device is used for implanting the suture lines into different valve leaflets of a cardiac valve, and the suture line knotting device is used for fixing the suture lines together. The suture lineimplanting device comprises a pushing guide pipe, a clamping component used for clamping the valve leaflets and a puncturing component used for puncturing the valve leaflets. The suture line knottingdevice comprises a suture line lock catch used for fixing the suture lines, a lock catch pushing device detachably connected with the suture line lock catch, and a pushing control device used for controlling the suture line lock catch to fix and release the suture lines. According to the system, the suture lines are implanted into the anterior lobe and the posterior lobe of the bicuspid valve respectively, then the suture lines are fixed together, and the gap in the bicuspid valve is reduced or eliminated, so that the bicuspid valve is prevented from forming two holes, mitral regurgitation istreated, the operation process is simple, the operation cost is low, the trauma degree of a patient is low, the complication risk is low, and the recovery process is relatively quick.

Description

technical field [0001] The invention belongs to the technical field of medical devices and relates to a heart valve repair system. Background technique [0002] The mitral valve is a one-way "valve" between the left atrium (abbreviation: LA) and the left ventricle (abbreviation: LV), which can ensure blood flow from the left atrium to the left ventricle. The leaflets of the mitral valve are divided into anterior leaflet and posterior leaflet. When the left ventricle is in a diastolic state, the two are in an open state, and blood flows from the left atrium to the left ventricle; when the left ventricle is in a systolic state, the chordae are stretched to ensure The leaflets are not flushed to the atrial side by blood flow. Figure 1a-1b A normal, healthy mitral valve is shown, with the anterior and posterior leaflets closed well, allowing blood to flow from the left ventricle through the aortic valve (abbreviated: AV) to the aorta. Figure 2a-2b The mitral valve shown is di...

Problems solved by technology

This interventional treatment method needs to be sent into the mitral valve clamp through a complicated and tortuous path in the patient's body, and it is impossible to visually observe whether the position of the mitral valve clamp in the patient's heart is reasonable, and the operator can only remotely operate the clamp outside the body. The cusp clamp clamps the valve leaflet and release process, so the operation time is longer and the success rate is lower
