Description
技术领域technical field
本实用新型涉及医用行业金属管材内表面处理装置领域,尤其涉及一种镁合金管材内表面电化学抛光结构。The utility model relates to the field of treatment devices for the inner surface of metal pipes in the medical industry, in particular to an electrochemical polishing structure for the inner surface of magnesium alloy pipes.
背景技术Background technique
近年来,常使用镁合金制作可吸收血管支架,因为镁元素存在于人体各种组织中,参与多种生物反应,同时,镁合金具有低密度、低弹性模量、高比强度、可降解等优点,因此镁合金作为新型可吸收医疗器械用材料具有先天优势。In recent years, magnesium alloys are often used to make absorbable vascular stents, because magnesium exists in various tissues of the human body and participates in various biological reactions. At the same time, magnesium alloys have low density, low elastic modulus, high specific strength, and are degradable. Therefore, magnesium alloy has inherent advantages as a new material for absorbable medical devices.
然而,镁合金血管支架所需的的镁合金管材大都是通过挤压、轧制、拉拔等工艺加工而成的,其形变过程容易在变形塑性低的镁合金管材的内表面留下变形皱褶,增加镁合金管材内表面的粗糙度,从而导致在对镁合金管材进行激光切割雕刻时,出现过烧或切不透的情况,进一步影响镁合金管材内表面的光洁程度。然而,作为介入医疗器械用材料,粗糙的内表面会造成血小板凝集及变形、凝血系统以及纤溶系统等受影响,影响生物相容,因此,需要对镁合金管材的内表面进行抛光处理。However, most of the magnesium alloy tubes required for magnesium alloy vascular stents are processed by extrusion, rolling, drawing and other processes, and the deformation process tends to leave deformation wrinkles on the inner surface of the magnesium alloy tubes with low deformation plasticity. The pleats increase the roughness of the inner surface of the magnesium alloy pipe, which leads to overburning or impenetrable cutting when laser cutting and engraving the magnesium alloy pipe, which further affects the smoothness of the inner surface of the magnesium alloy pipe. However, as a material for interventional medical devices, the rough inner surface will cause platelet aggregation and deformation, affect the coagulation system and fibrinolytic system, and affect biocompatibility. Therefore, the inner surface of the magnesium alloy tube needs to be polished.
由于作为血管支架的镁合金管材的内径小,不宜通过机械加工的方式处理镁合金管材的内表面;通过化学处理不易控制反应程度以及抛光均匀性,难以有效地消除镁合金管材内表面的粗糙度;电化学抛光的方式相对合适,因此,有必要设计一种镁合金管材内表面电化学抛光结构,以实现对镁合金管材内表面进行快捷有效的抛光处理。Due to the small inner diameter of the magnesium alloy tube used as a vascular stent, it is not suitable to treat the inner surface of the magnesium alloy tube by mechanical processing; it is difficult to control the degree of reaction and the uniformity of polishing through chemical treatment, and it is difficult to effectively eliminate the roughness of the inner surface of the magnesium alloy tube The way of electrochemical polishing is relatively suitable. Therefore, it is necessary to design an electrochemical polishing structure for the inner surface of magnesium alloy pipes to realize fast and effective polishing treatment on the inner surface of magnesium alloy pipes.
