Cardiac apex implantation cuspid valve clamping device and cardiac apex implantation cuspid valve clamping method

Abstract

The present invention discloses a cardiac apex implantation cuspid valve clamping device and a cardiac apex implantation cuspid valve clamping method. The cardiac apex implantation cuspid valve clamping device comprises an upper connecting piece, a sealing end piece and a central woven net are sequentially arranged on the upper connecting piece, a rod penetrating cavity is formed in the central woven net, and the upper connecting mechanism is arranged at a near end of the sealing end piece; an inner frame net is connected with a lower end of the central woven net to form an integrated structure; an outer edge of an outer frame net is integrally connected with an outer edge of the inner frame net, besides, a lantern ring is arranged in a middle part of the outer frame net, and a lower connecting mechanism is arranged on an outer ring surface of the lantern ring; elastic clamps are fixed on a surface of the inner frame net; a clamp opening mechanism is used for controlling the elastic clamps to open; an initial memory state of the outer frame net is folding and wrapping the inner frame net and elastic clamps towards a far end. During compression intervention, the cardiac apex implantation cuspid valve clamping device greatly reduces aperture diameter, a small-aperture diameter sheathing canal can be intervened, difficulties and strengths of surgeries are reduced, the large-widthelastic clamps can be used, a capture success rate is increased, the elastic clamps are independently controlled through corresponding pull wires, capture of valve leaflets is easy to control, and universality is strong.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an apex-implanted cusp valve clamping device and a cardiac apex-implanted cusp-valve clamping method. Background technique [0002] With the aging of the population, the incidence of heart valve disease is gradually increasing, followed by the incidence of mitral regurgitation is also showing a rising trend. According to statistics, among heart valve diseases, mitral valve disease accounts for 70% of valve diseases, which accounts for a large proportion. [0003] With the development of science and technology, domestic and foreign device manufacturers have developed a batch of interventional devices for the treatment of mitral valve regurgitation. Among them, Abbott MitraClip and Edward PASCAL are typical representatives. MitraClip was popularized earlier in clinical practice. The mechanical working principle of the clip design is a four-bar linkage structure. The femor...
