主　　题：Rotational atherectomy Grinding tool Grinding performance Parameter analysis 

摘      要：Rotational atherectomy is an effective treatment for severe vascular calcification obstruction,and relies on high-speed grinding(typically 130,000–210,000 r/min)with miniature grinding tools to remove calcified tissue and restore blood ***,reports of intraoperative complications are common because of the grinding force,temperature,and debris directly acting on the body during the grinding process,which can easily cause damage to *** this study,three novel grinding tools were designed and fabricated and a series of experiments have been conducted to analyze the effects of tool geometry and parameters on grinding performance,that is,force,temperature,and specimen surface *** results show that these tools can effectively remove simulated calcified tissue and that they have two motions,rotation and revolution,in the *** higher rotational speeds,grinding force and temperature increase noticeably,while the amount of debris decreases *** addition,by observing the surface morphology of the specimens,we concluded that the material removal rate per unit time is influenced by both rotational speed and tool geometry,and that high rotational speed and a rough tool surface can improve the material removal rate efficiently.
