Abstract: A left atrial appendage ligator having a ligature and operating handle. One end of the operating handle is fixedly connected with a support rod, the inner wall of the support rod is fixedly connected with a feeding pipe and locking pipe. A first sliding groove is formed in the inner side wall of the feeding pipe. The inner side wall of the first sliding groove is slidably connected with a first sliding block. The middle part of the first sliding block is fixedly connected with a feeding push rod. One end of the feeding push rod is fixedly connected with a first hook. One side of the first sliding block is fixedly connected with a return spring. The left atrial appendage ligator has a locking push rod, ligature, hanger knot and supporting component. The ligature is prearranged on a sleeve pipe portion to form the hanger knot to avoid knotting during the operation process. During operation, the knotting can be completed only by locking the hanger knot.
