Description
Technical Field
The invention relates to the field of interventional medical instruments, in particular to a left atrial appendage occluder capable of adjusting angles in multiple directions.
Background
Atrial fibrillation (atrial fibrillation for short), namely arrhythmia, frequently occurs in old people, and the incidence rate of atrial fibrillation is increased continuously with the age, and the population over 75 years old can reach 10 percent. When atrial fibrillation occurs, the heartbeat frequency is often fast and irregular, so that the atrium loses the effective contraction function, and blood is easy to gather in the atrium, particularly in the left atrial appendage, so that the formation of thrombus is accelerated. After the thrombus falls off, the thrombus can flow into all parts of the body along with blood, and the damages such as cerebral apoplexy, limb arterial embolism and the like are easily caused. The stroke is the most serious complication caused by atrial fibrillation, has the characteristics of high morbidity, high mortality and high disability rate, and is the leading cause of the disability of the adults in China. The study showed that more than 90% of patients with atrial fibrillation had thrombi formed in the left atrial appendage. Therefore, the risk of disability and death of patients with atrial fibrillation due to thrombus can be reduced by preventing thrombus formation at the left atrial appendage.
Anticoagulation is a necessary means for preventing thrombosis and embolism of atrial fibrillation patients, but anticoagulation has some limitations, such as increased risk of bleeding, susceptibility to influence of other drugs or diet in practical use, need to detect INR for long-term use, and many patients cannot persist for a long time. Therefore, currently, an interventional therapy method for occluding the left atrial appendage by implanting a left atrial appendage occluder is often used. At present, the left atrial appendage occluder on the market is mainly divided into an inner plug type left atrial appendage occluder and a plug disc type left atrial appendage occluder. The inner plug type left auricle occluder is supported by a metal framework with shape memory capacity, integrated barbs are arranged on the periphery of the inner plug type left auricle occluder, the inner plug type left auricle occluder is fixed in the left auricle after the instrument is released, and a flow blocking film is arranged in the instrument and can block blood from entering and exiting the left auricle.
The granted publication No. CN208693357 discloses an inner plug type left atrial appendage occluder, which has only a plugging column for embedding a column body part in the left atrial appendage and a column occluding part covering the opening of the left atrial appendage, the periphery of the plugging column body part is provided with a plurality of barbs for anchoring on the inner wall of the left atrial appendage, but is limited by the complexity of the shape of the left atrial appendage, the occluder has a narrow application range and cannot be completely matched with all left atrial appendage structures; the grant publication No. CN208693356U discloses a plug disc type left atrial appendage occluder, the structure includes a plug column embedded in the left atrial appendage, a cover plate covering the opening of the left atrial appendage and an intermediate fixing sleeve, but because a rigid connecting piece is arranged between the occlusion structure and the fixing structure, the angle adjustment between the occlusion disc and the fixing disc is difficult to realize independently, once the fixing disc enters the left atrial appendage for fixation, the angle adjustment can not be carried out by the occlusion disc, the structure can not meet the complicated inner cavity of the left atrial appendage, and also can cause partial blood leakage, can not completely seal the left atrial appendage, and influences the effect of preventing left atrial appendage thrombus; the publication number CN109662745A discloses a plug disc type left atrial appendage occluder with an adjustable angle, wherein a connecting piece part is a first unit and a second unit, the first unit is connected with an occluding structure, the second unit is connected with a fixed structure, and the first unit is rotationally connected with the second unit.
