Abstract

The invention provides an occluder. The occluder comprises a first occluding part and a second occluding part, a connecting bolt is arranged at the far end of the first occluding part along the direction of the second occluding part, a first external thread is arranged on the side wall of the connecting bolt, a protruding part is arranged at the near end of the second occluding part, a through hole is formed in the protruding part, a second external thread is arranged on the side wall of the protruding part, the thread direction of the first external thread is opposite to that of the second external thread, and the near end of the connecting bolt can penetrate through the through hole to be in threaded connection with a nut. The invention further provides an occluder locking system and a locking method thereof. According to the structure of the occluder, efficient, stable and reliable locking can be achieved under the combined action of a pushing device, so that the service life and the occluding effect of the occluder are prolonged, the risk of postoperative complications is reduced, and the occluder is particularly suitable for occluding treatment of aortic dissection crevasses.

Description

technical field [0001] The invention relates to the technical field of medical devices, and in particular to an occluder, an occluder locking system for delivering the occluder, and a locking method for the occluder locking system. Background technique [0002] The delivery system of an intracavitary occluder (such as left atrial appendage occluder, vascular plug, filter, etc.) usually includes several parts such as a delivery sheath device, an expansion device, a loading device, and a pushing device. The delivery sheath device and the expansion device first establish a channel, then withdraw the expansion device, put the occluder into the loading device through the pushing device, then connect the delivery sheath device and the loading device, and introduce the occluder into the delivery sheath through the pushing device until the occluder is delivered to the targeted location. With the development of catheter interventional therapy methods, various endoluminal occluders h...
