Abstract

The invention provides an electrochemical polishing device and method for a support. The device and method are mainly suitable for electrochemical polishing of the medical metal support. The electrochemical polishing device for the support is characterized by comprising a metal anode, a metal cathode of a cylindrical structure, an electrochemical polishing tank and the like, and in the electrochemical polishing process, the current can be evenly distributed to all the portions of the support. The device is suitable for electrochemical polishing of the metal support such as a nickel-titanium alloy support, a cobalt-chromium alloy support, a stainless steel alloy support and a titanium alloy support and is used for improving the phenomena that pits and protrusions are generated on the inner surface of a support and the inner surface is not smooth and bright in the electrochemical polishing process, and the electrochemical polishing effect of the inner surface of the support is improved, so that both the inner surface and the outer surface of the support can achieve the good mirror surface effect. By the adoption of the device and method, the problem that the removing amount of the head end of the support is large can be solved as well, the polishing evenness of the support is improved, and therefore the metal surface of the support is smooth and bright.

Description

technical field [0001] The invention relates to the field of minimally invasive interventional medical metal stents, in particular to an electrochemical polishing device and polishing method for a stent, belonging to the field of medical devices. Background technique [0002] Medical metal stents can be made of stainless steel, titanium alloy, nickel-titanium alloy, cobalt-chromium alloy and other metals, and are prepared by laser cutting or weaving. Medical metal stents are mainly used in the tissue cavity or blood vessel cavity in the body to expand the tissue cavity or blood vessel cavity to treat the narrowing and blockage of the tissue cavity or blood vessel cavity. Electrochemical polishing is the use of electrochemical methods to polish medical metal stents with electrochemical polishing liquid, which can make the surface of the metal stent smooth and bright, achieving a mirror effect. Electrochemical polishing can improve the biocompatibility and corrosion resistanc...
