An artificial chord interventional device

Abstract

The invention discloses an artificial tendon intervention apparatus comprising a head, a connecting tube and a control lever. An artificial tendon is connected with the head. The head is composed of a concave part and a convex part fastened together. The control lever allows the head to be opened or closed or released through a connecting rod. The head and the connecting tube partially enter the left ventricle through the cardiac apex and arrive at the proper position of the bicuspid valve; by regulating the control lever, the head is opened, closed or released; the head is connected with the artificial tendon; by adjusting the length of the artificial tendon, intervention of the artificial tendon is achieved. The artificial tendon intervention apparatus is simple in design and efficient and simple to operate, allows shorter surgical time, is good in repeatability and has promising clinical application prospect.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to an artificial chord interventional device. Background technique [0002] Mitral regurgitation is one of the most common valvular lesions today, the main causes are mitral annulus dilatation, chordal insufficiency, mitral valve mucus degeneration, valve leaflet prolapse, rheumatic heart valve disease, ischemic lesions Wait. [0003] Direct mitral valvuloplasty and artificial valve replacement are the most effective methods for the treatment of mitral valve insufficiency, but because the operation requires extracorporeal circulation technical support, the trauma to the human body is relatively large, and there are many complications for elderly patients. disease patients, there are quite high morbidity and mortality. Therefore, in recent years, medical personnel and scientific researchers from various countries have explored percutaneous mitral valve repair techniques, mainly inclu...

Problems solved by technology

[0003] Direct mitral valvuloplasty and artificial valve replacement are the most effective methods for the treatment of mitral valve insufficiency, but because the operation requires extracorporeal circulation technical support, the trauma to the human body is relatively large, and there are many complications for elderly patients. patients with a relatively high rate of morbidity and mortality

[0004] Although the MitraClip technology has shown its good application prospects, there are still some problems: ①It is difficult to insert from the femoral artery through a long sheath, and the operation time is long; ②Due to the large diameter sheath used in the operation, there may be residual Atrial septal residual leakage; ③ Changing the mitral valve opening from a single hole to a double hole will reduce the area of ​​the mitral valve opening; ④ Fixing the prolapsed valve and the healthy valve together will theoretically increase the chordae at the healthy valve tension, accelerating its degradation
