摘　　要：旋磨术是治疗血管钙化病变的一种微创技术,通过微型砂轮去除堵塞在血管内的钙化斑块组织,达到疏通血管、重建血液流动的目的。钙化斑块组织堵塞血管造成供血不足,易诱发多种心血管疾病,其硬度较大导致球囊和支架无法撑开,目前临床上普遍采用旋磨术进行疏通。首先综述了旋磨术的相关研究成果和发展趋势,并对旋磨器械发展进行了介绍;其次总结了旋磨术优劣势的相关内容;然后对旋磨机理进行了详细的分析;最后总结了旋磨术目前存在的不足与未来的研究方向。Significance:Plaques are clogging deposits formed by the accumulation of fat and calcium on the inner walls of arteries.Their formation can lead to narrowing the inner diameter of the blood vessel and hardening the blood vessel wall,thereby limiting blood flow and inducing various cardiovascular diseases such as coronary heart disease and peripheral arterial disease.Numerous factors,such as lifestyle changes and population aging,have lead to an increase in the number of patients with cardiovascular disease in China in recent years.The annual growth rate of vascular interven-tional therapy has remained at around 17%for a decade due to the continuous development of interventional medical means.China's large population of vascular disease and the special situation of calcified plaque lesions have created a huge demand for rotational interventional therapy.By analyzing the current research on rotary grinding,this paper sum-marizes the existing deficiencies and suggests a follow-up research direction to accelerate the exploration of rotary grinding's mechanism and master the core technology theory.Progress:Firstly,the research on rotary grinding instru-ments is summed up in three parts:(1)The rotary grinding therapeutic apparatus mentioned here contains a description of its basic features,including the RA from Boston Science and the OA from CSI.The differences between the two were compared in terms of technical indications,clinical indications,mechanism of action,and product upgrades.(2)The pre-paration method for the grinding wheel and the differential cutting of the grinding wheel are presented in summary.Cur-rently,grinding wheels are mostly created by electroplating,and some experts have suggested using the"engraving"technique.Differential grinding wheel cutting involves two primary principles.Boston Science proposed differential cutting that utilizes the theory of workpiece deformation during the cutting process of flexible materials.The second mechanism is based upon the theory of the dynamic pressure film in wa
