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. The sleeve pipe portion serves as support for threading the other end of the ligature to avoid automatic locking. After the sleeve pipe portion is separated from the hanger knot, the hanger knot can be pulled for automatic locking.
