HOOK AND OCCLUSION DEVICE

Abstract

Disclosed is a hook and an occlusion device. The hook is used for being fixed to the occlusion device. The occlusion device is formed by interweaving a first-direction line and a second-direction line. The hook comprises a positioning body and a hook part, wherein the positioning body is provided with a first positioning part and a second positioning part, and the first positioning part and the second positioning part are used for limiting the hook to the first-direction line and the second-direction line, respectively, or the first positioning part and the second positioning part are used for simultaneously limiting, in different directions of force, the hook in the axial direction to the first-direction line/the second-direction line; the hook part is formed by bending the positioning body, an included angle ? is formed between the projection of the hook part on the positioning body and the axis of the positioning body, and the value range of the included angle ? is greater than 0 degrees and smaller than 90 degrees. The hook provided by the present invention can be fixed to the occlusion device without other auxiliary parts such as suture lines, is excellent in stability and firmness, and can increase the supporting strength of the occlusion device.
