1. 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.
