ABSTRACT: With the continuous in-depth research and clinical exploration of related technologies in magnetic surgery, the demand for implanting NdFeB magnets has been increasing, and the surface requirements for the magnets implanted into the human body have also been continuously improved. Because of the different physiological environments of different implantation sites in the human body, the requirements for surface modification are also different. At present, the surface modification methods of NdFeB magnetic materials implanted in vivo are various, but the effect of surface modification in different parts of the human body is not yet definitive, and the lack of systematic evaluation. In this paper, the implanted environment and a variety of surface modification methods of the existing medical NdFeB magnets are summarized in detail. The problems existing in the surface modification at the current stage are summarized in order to provide ideas and directions for follow-up study. |
