抗菌不锈钢外科手术器械的研发

摘要

ObjectiveTo explore the research and development of surgical instruments made of and its feasibility of clinical application.Methods The copper-bearing martensite antibacterial stainless steel with intellectual property rights was used to manufacture the antibacterial surgical instruments. According to the related testing standards, the hardness, corrosion resistance and antibacterial performance of antibacterial instruments were evaluated.Results The hardness of antibacterial stainless steel could reach 48-52 HRC, and the corrosion resistance evaluated by the boiling water test was grade A, all satisfied relevant industrial standards of surgical instruments. The antibacterial tests operated by the third-party inspection institution also indicated that all the antibacterial rates of antibacterial surgical instruments against staphylococcus aureus, escherichia coli, pseudomonas aeruginosa and salmonella aertrycke exceeded 99%, showing a broad-spectrum antibacterial effectiveness.Conclusion The application of antibacterial stainless steel on surgical instruments can effectively reduce risk of bacterial infection.%目的：探讨抗菌不锈钢外科手术器械的研发以及在临床应用的可行性。方法采用自主知识产权的含铜马氏体抗菌不锈钢（2Cr13Cu）来研发抗菌外科手术器械并依据相关检测标准评价其硬度、耐蚀性能和抗菌性能。结果抗菌不锈钢手术器械的硬度可达48~52 HRC，沸水试验耐蚀性能评价为A级，均能满足手术器械相应行业标准要求。第三方的抗菌性能检测结果也显示，抗菌不锈钢手术器械对院内环境常见的金黄色葡萄球菌、大肠杆菌、铜绿假单胞杆菌、鼠伤寒沙门氏菌的杀菌率均在99%以上，具备优异的广谱抗菌性能。结论本院研发的抗菌不锈钢在外科手术器械上的应用可有效降低细菌感染风险。
