近年来,由于生物医学工程和组织工程学及其相关学科,如材料学、生物力学、表面化学、蛋白质组学、基因组学等的发展,以及激光烧结成形,计算机辅助设计与制造(CAD-CAM)等相关制备工艺和micro CT等检测技术的突飞猛进的发展,体内植入物也得到飞速的发展[1-2]。常用的体内植入物包括心脏瓣膜、假体眼球、骨组织植入物等,而骨组织植入物包括修复患者关节的人工节关,长骨和脊柱受伤的人工骨椎、骨科固定板和 In recent years, due to the development of biomedical engineering and tissue engineering and related disciplines such as material science, biomechanics, surface chemistry, proteomics, genomics and so on, as well as laser sintering forming, computer aided design and manufacturing (CAD-CAM ) And other related preparation technology and micro CT and other detection technologies by leaps and bounds, the rapid development of implant has also been [1-2]. Commonly used in-vivo implants include heart valves, prosthetic eyeballs, bone tissue implants and the like, while bone tissue implants include artificial joints that repair the patient’s joints, artificial bone spines that have long and spine injuries, orthopedic fixation plates and
