The present invention relates to a Left atrial appendage occluder comprising an elastic closure disc. The left atrial appendage occluder also comprises an elastic fixing frame connected with the closure disc and located on one side of the closure disc. The fixing frame comprises a central end connected with the closure disc and a plurality of interconnected and bent struts, wherein at least one anchor is set near the end of at least one strut with the anchor pointing toward the closure disc. The left atrial appendage occluder has a stable structure, a good positioning and sealing effect on the cavity wall in the left atrial appendage, and it is easy to position repeatedly; it can also be recycled before separating from a conveyor. When in surgical operation, the left atrial appendage occluder can select the position area based on the actual shape and size of the patient's left atrial appendage, so the surgical risk is lowered.
A left atrial appendage occluder comprising an elastic closure disc, a central end connected with the closure disc, and an elastic fixing frame, wherein the fixing frame is deployed at one side of the closure disc and comprises a plurality of radial struts directly connected to and extending radially away from the central end and away from the closure disc, and each radial strut comprises a curve extending to a tail end, wherein each radial strut extends from the tail end and further divides at a first junction into two branches at the curve, and adjacent strut branches of adjacent struts extending from the first junctions are interconnected via second junctions into a whole and are then gathered onto the central end, wherein each tail end is spaced apart from each adjacent tail end and each tail end is free and spaced apart from the closure disc and each of the first junctions.
