Abstract

The invention provides a left auricle plugging device. The left auricle plugging device comprises multiple claw hooks and a first elastic connecting piece connected with the multiple claw hooks through a fixed structure; the first elastic connecting piece is used for providing a radial expansion force for the multiple claw hooks, namely, enabling the fixed structure to be higher in expansion capability, thereby enabling the left auricle plugging device to be better suitable for left auricles of different shapes, as well as realizing recycling of the left auricle plugging device more easily; furthermore, detachable first part and second part are adopted; the second part moves in the extension direction of the first part so as to realize adjustment of depth / length of the left auricle plugging device so as to be suitable for left auricles of different depths; in addition, the second part and the fixed structure are detachable, so as to be suitable for left auricles of different shapes and sizes; and the second part can be connected with fixed structures of different dimensions selectively, so as to be suitable for left auricles of different shapes.

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...
