Problems solved by technology

However, the deep part of the left atrial appendage cavity is also the thinner part of the left atrial appendage wall, which may easily cause the fixed parts to puncture the left atrial appendage wall, which may cause pericardial effusion and even cardiac tamponade and other adverse consequences

Embodiment Construction

[0036] In order to describe the structure of the left atrial appendage occluder more clearly, the present invention defines the terms "distal end" and "proximal end", which are commonly used terms in the field of interventional medical devices. Specifically, "distal end" means the end away from the operator during the operation, and "near end" means the end close to the operator during the operation.

[0037] figure 1 It shows a schematic view of the left atrial appendage occluder implanted in the left atrial appendage according to an embodiment of the present invention. The left atrial appendage 2 is located in the left atrium 1 , between the mitral valve (not shown) and the left superior pulmonary vein 4 . Also refer to figure 2 The left atrial appendage occluder includes a sealing disk 31 , a fixing frame 33 located on the distal side of the sealing disk 31 , and a connecting piece 32 connecting the sealing disk 31 and the fixing frame 33 .

Abstract

The invention relates to a left auricle occluder. The left auricle occluder comprises a sealing disc and a fixing rack located on one side of a far end of the sealing disc. The left auricle occluder further comprises a connecting part connecting the sealing disc with the fixing rack. The fixing rack comprises a framework structure. The framework structure comprises a near-end side surface and a support peripheral surface which is connected to the near-end side surface and extends towards the far end. The connecting part is connected with the near-end side surface. The left auricle occluder has the following beneficial effects: the fixing rack is configured to be in the structure with one enclosed end and an opened end composed of at least two support rods; therefore, enough support force for the fixing rack is ensured while each support rod is independent of each other; support rods can maintain good pasting and covering performance of a cavity wall of a left auricle; stability and fixation performance of the fixing rack in the left auricle are enhanced; and the fixing rack can be fixed in the left auricle without needing to set an anchor thorn so that damage to the cavity wall of the left auricle is avoided.

Description

technical field [0001] The invention relates to medical equipment, in particular to a left atrial appendage occluder. Background technique [0002] At present, an occluder can be placed in the left atrial appendage through catheter intervention to prevent the formation of a thrombus in the left atrial appendage due to atrial fibrillation, avoiding the stroke caused by the thrombus ascending to the brain; or preventing the thrombus from reaching other parts of the body through the human blood circulation system. systemic embolism. This type of left atrial appendage occluder can roughly include an integral type occluder and a split type occluder structurally. For example, a split occluder usually includes a fixing part and a sealing part connected to each other. The fixing part is placed in the cavity of the left atrial appendage to fix the entire occluder, and the sealing part seals the ostium of the left atrial appendage for blocking blood flow into the Inside the cavity o...
