Abstract:
An inferior vena cava filter comprises a recovery hook (1), a connection component (12), and multiple supporting rods. The connection component (12) is disposed below the recovery hook (1), and a component connected to a push device is disposed in the connection component. Multiple first supporting rods (4) are divided from the lower part of the connection component (12). One second supporting rod (2) and two third supporting rods (5) are divided from the far end of each first supporting rod (4). One part of the far end of the second supporting rod (2) is upwards and downwards bent to form a hook shape. The third supporting rods (5) continue to be downwards extended, and in unfolding, the third supporting rods (5) and the third supporting rods (5) divided from the first supporting rods (4) are extended in an inner arc shape, and the lower ends of the adjacent two third supporting rods (5) divided from the adjacent two first supporting rods (4) get close. In unfolding, the supporting rods are folded to form a filtering net shape on the whole.
