Disclosed is an occlusion device having an angle variable flat disk, comprising a single-layer disk (4), a plug (6) and a waist (5) connecting the single-layer disk (4) and the plug (6). The single-layer disk (4) is braided from elastic strands and comprises a plurality of radially-arranged support rods (40). Grids braided from elastic strands are provided on the surface of the plug (6). The waist (5) comprises at least one connecting strand. An annular interlocking structure is provided in the center of the single-layer disk (4). The plurality of support rods (40) are connected into a flat integral body via the annular interlocking structure. The connecting strand of the waist (5) is connected to the annular interlocking structure and the grids of the plug (6). The occlusion device has the features of a flat single-layer disk and a flexible waist structure at the same time, and the single-layer disk has the function of adaptive regulation of morphology and is able to effectively adapt to different physiological structures while reducing complications.
