医用生物材料研究进展 摘要 生物医用材料（biomedical material）是用于对生物体进行诊断、治疗、修复或替换其病损组织、器官或增进其功能的新型高技术材料。它是研究人工器官和医疗器械的基础，己成为材料学科的重要分支，尤其是随着生物技术的莲勃发展和重大突破，生物材料己成为各国科学家竞相进行研究和开发的热点。当代生物材料已处于实现重大突破的边缘，不远的将来，科学家有可能借助于生物材料设计和制造整个人体器官，生物医用材料和制品产业将发展成为本世纪世界经济的一个支柱产业。 由生物分子构成生物材料，再由生物材料构成生物部件。生物体内各种材料和部件有各自的生物功能。它们可以做生物部件的人工代替物，也可以在非医学领域中使用。前者如人工瓣膜、人工关节等；后者则有模拟生物黏合剂、模拟酶、模拟生物膜等。关键词：生物，医学，材料，医疗器械，创伤，组织，植入Abstract Biological medical material ( biomedical material ) is used for diagnosis, treatment, biological repair or replacement of the diseased tissues, organs or promote its function of new high-tech materials. It is the study of artificial organs and medical equipment foundation, has become an important branch of material science, especially with the development of biological technology Lianbo and major breakthrough, biological material has become the scientists to conduct research and development focus. The biological material is to achieve a major breakthrough in edge, not far in the future, scientists may have with the help of biological materials design and manufacture of the body organs, biomedical materials and products industry will become this century the world economy a pillar industry. Biological molecules from biological material, the biological material biological components. Organisms for various materials and elements have respective biological function. They can be used as biological components of artificial substitutes, can also be used in the field of medicine in non. The former such as artificial heart valve, such as artificial joint; the latter have simulated biological adhesive, enzyme mimics, simulated biological membrane. Key words: biology, medicine, materials, medical equipment, trauma, tissue, implantation 1、生物医用复合材料的研究现状与应用 　　陶瓷基生物医用复合材料 　　 陶瓷基复合材料是以陶瓷、玻璃或玻璃陶瓷基体，通过不同方式引入颗粒、晶片、晶须或纤维等形状的增强体材料而获得的一类复合材料。目前生物陶瓷基复合材料虽没有多少品种达到临床应用阶段，但它已成为生物陶瓷研究中最为活跃的领域，其研究主要集中于生物材料的活性和骨结合性能研究以及材料增强研究等。 羟基磷灰石
