The interventional device formed by the laser engraving process occupies a large specific gravity, and after the interventional device is subjected to laser cutting or heat treatment shaping, the surface of the interventional device has defects such as pits, scratches, burrs, oxide layers and the like, if the interventional device is directly implanted into a human body without treatment, blood platelets in blood vessels can be adhered, thrombus and intimal hyperplasia are easy to form, or blood vessels are easy to scratch when the thrombus is removed mechanically through an intracranial thrombus removal bracket. In particular, cardiac stents have a higher requirement for surface roughness, and thus, the cut or heat treated stents also require polishing processes.
Research shows that during electrolytic polishing, the stirring of the electrolyte can often improve the polishing quality, because the electrolyte can update the polishing liquid near the surface of the anode, the temperature of the polishing liquid is more uniform, the local overheating of the metal surface is prevented, and the dissolution speed of a mucous membrane is accelerated, so that the polishing speed is improved; meanwhile, bubbles remained on the surface of the metal can be removed by stirring, so that pits or stripes can be eliminated.

However, by means of the magnetic stirring mode, the flowing of electrolyte on the inner surface of the support is relatively slow, and the interaction of ions on the outer surface of the support is caused, so that the polishing removal amount of the inner surface of the support is insufficient, and the polishing quality of the inner surface is poor. The polishing tank disclosed by the inventor is provided with a stirring mechanism, wherein the stirring mechanism comprises a base arranged at the bottom of the polishing tank, a motor, a rotating rod and stirring impeller blades arranged on the rotating rod, the rotating rod penetrates through the bottom of the polishing tank, the stirring impeller blades are positioned in polishing electrolyte, and a polished support is vertically immersed in the polishing electrolyte; in the patent application, the stirring mechanism is arranged, so that the flowing speed of the polishing electrolyte is enhanced, and an axially flowing electrolyte circulating flow is generated, so that the polishing electrolyte is uniformly distributed, and the polishing efficiency is accelerated; however, the electrolyte circulation flow formed by the stirring mechanism and the polishing support form an included angle, so that the inner surface of the support cannot be well and uniformly flushed, the polishing removal amount of part of the surface in the support is insufficient, and the inner surface of the support is finally uneven in polishing and poor in polishing quality.
