The invention discloses a blood vessel filter and a processing method thereof, and the blood vessel filter comprises a filter arm which is an elastic structure for filtering thrombus; the filtering arm comprises an elastic outer supporting arm arranged in the length direction of the filtering arm and a filtering net composed of a plurality of elastic supporting arms. The degradation ring is of an annular structure; a lantern ring is arranged at one end, facing the degradation ring, of the elastic supporting arm, and the degradation ring is sleeved with the lantern ring; the blood vessel filter has an open state and a folded state, and in the process that the blood vessel filter is converted from the open state to the folded state, the lantern ring relatively slides on the degradation ring. By means of the structure, the problem that an existing blood vessel filter is difficult to convey due to the fact that the blood vessel filter in the prior art is large in production and machining difficulty and insufficie
