Embodiment 1

[0038] Please refer to Figure 1 to Figure 3 ,in, figure 1 It is a partial structural schematic diagram of the left atrial appendage occluder according to Embodiment 1 of the present invention; figure 2 It is a structural schematic diagram of the left atrial appendage occluder according to Embodiment 1 of the present invention; image 3 It is a structural schematic diagram of the fixing structure of Embodiment 1 of the present invention.

[0039] Such as Figure 1 to Figure 3 As shown, in the embodiment of the present application, the left atrial appendage occluder 1 includes: an occlusion structure 10, and the occlusion structure 10 includes a first connecting member 11 and a sealing member fixed on the first connecting member 11. Blocking member 12; fixed structure 20, said fixed structure 20 includes a second connecting member 21 and a fixing member 22 fixed on said second connecting member 21; wherein said first connecting member 11 and second connecting member 21 sep...

Embodiment 2

[0052] Please refer to Figure 8 , which is a schematic structural diagram of the left atrial appendage occluder according to Embodiment 2 of the present invention. Such as Figure 8 As shown, the left atrial appendage occluder 2 includes: a occluding structure 30, the occluding structure 30 includes a first connecting piece 31 and a occluding piece 32 fixed on the first connecting piece 31; a fixing structure 40 , the fixing structure 40 includes a second connecting piece 41 and a fixing piece 42 fixed on the second connecting piece 41 ; wherein, the first connecting piece 31 is separated from or fixed to the second connecting piece 41 . Therefore, when faced with left atrial appendages of various shapes and depths, the first connecting member 31 is separated from the second connecting member 41, and after selecting a suitable fixing structure 40, the first connecting member 31 and the second connecting member 41 are correspondingly connected. After the second connecting pi...

Abstract

The invention provides a left auricle plugging device. A plugging structure comprises a first connecting piece and a plugging piece fixed on the first connecting piece, a fixing structure comprises a second connecting piece and a fixing piece which is fixed on the second connecting piece, the first connecting piece and the second connecting piece are separated or fixed, so that when the left auricle plugging device is applied to the left auricles different in shape and different in depth, the first connecting piece is separated from the second connecting piece, after the suitable fixing structure is selected, the first connecting piece and the second connecting pieces are adopted for fixing correspondingly, so that the left auricle is plugged, namely, adaptive selection can be carried out according to the different left auricles, and thus the left auricle plugging device can well adapt to the left auricles different in shape and different in depth.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a left atrial appendage occluder. Background technique [0002] Atrial fibrillation (AF) is the most common persistent cardiac arrhythmia clinically, and the incidence rate of atrial fibrillation in the general population is 0.5% to 1.3%. The main hazard of atrial fibrillation is the promotion of thrombus formation. After the thrombus falls off, it is easy to cause complications such as stroke and peripheral vascular embolism, which significantly increases the disability rate and mortality rate. Stroke is the most common and most harmful complication of atrial fibrillation. About 15 million people worldwide suffer from stroke every year, of which 20% to 25% are attributed to atrial fibrillation. Studies have shown that 60% of patients with rheumatic heart disease and atrial fibrillation have cardiogenic thrombus from the left atrial appendage, and more than 90% of pa...
