炭石墨材料的生物机械性能和骨固定材料

综合分析了炭材料的性能及其在生物医学方面的应用，重点分析了炭材料的生物机械性能，特别是生物力学相容性。结合国内外在基础医学和临床医学相关研究实例，认为炭材料不仅可以作为膺复体(Prothesis)长时间植入人体，也可作为骨折外固定材料(如夹具、夹板等)短时间使用。与传统金属和高分子材料相比，炭材料在生物相容性、强度、重量、稳定性、加工性、实际操作等上具有突出的优势。炭材料可被X射线穿透的特性，有助于临床医师利用良好的射线透射图像对所植入的碳材料膺复体进行准确定位和复位。另外，接受炭材料植入的骨肿瘤患者，术后可进行正常的放射治疗。

PROPERTIES OF CARBON MATERIALS AS FIXATOR FRACTURE FRAME AND BONE

The biomechanical and biocompatible properties of carbon materials were analyzed. Carbon materials have unique advantages for use in orthopedic surgery because of its high strength, biocompatibility and weight ratios, and can be easily machined into implant and fixator fracture frame as biomedical materials. Because of the excellent radiolucent of carbon materials in the X-ray, the carbon implant or fixation frame can be evaluated easily by clinical X-ray photography and CT scan techniques that are helpful for patients. It can be utilized in long-term hip implantation, as well as in short-term clinical fracture fixation.
