Abstract

The invention relates to the technical field of medical instruments, and discloses a left auricle plugging device. The left auricle plugging device comprises a plugging device framework, a release cap, a pushing rod and an adjusting line, the plugging device framework is installed at the first end of the release cap, the second end of the release cap is detachably installed on the pushing rod, and the pushing rod is used for conveying the plugging device framework to a preset position. The first end of the adjusting line is connected to the release cap or the plugging device framework, the second end of the adjusting line is connected to the end, away from the release cap, of the pushing rod, and the adjusting line is configured to adjust the installation position of the plugging device framework. According to the left auricle plugging device, control over the left auricle plugging device by a doctor is effectively increased, repeated positioning, releasing and recycling of the left auricle plugging device can be easily achieved, damage to human tissue is effectively avoided, the operation risk is reduced, the treatment cost is reduced, and pain of a patient is relieved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a left atrial appendage occluder. Background technique [0002] Atrial fibrillation (AF) is the most common sustained cardiac arrhythmia in clinical practice. At present, the occluder can be placed in the left atrial appendage through catheter intervention to prevent the formation of thrombus in the left atrial appendage due to atrial fibrillation, and to avoid the stroke caused by the thrombus ascending to the brain; or to prevent the thrombus from reaching other parts of the body through the human blood circulation system, systemic embolism. [0003] In the prior art, most left atrial appendage occluders are of the cage occlusion type. Generally, a cage-shaped occlusion-type left atrial appendage occluder includes a proximal fixed connector, a distal element is an occluder frame, and the occluder frame may have an anchoring structure. However, the existing left atria...
