Description

一种高生物活性聚醚醚酮复合材料人工假体及其制备方法
技术领域
本发明涉及一种高生物活性聚醚醚酮复合材料人工假体及其制备方法。本发明属于新材料领域。
背景技术
骨在人体中起着支撑、造血以及维持血钙平衡的重要功能,骨损伤会严重地影响人体健康和患者的生活质量。据统计,我国每年因各类交通、生产事故以及骨科疾病等因素造成的骨缺损或骨损伤患者多达数千万人,其中大约有200万病人需要做关节置换手术。骨损伤严重影响患者的生活质量,成为严峻的社会问题。
目前所用人工骨替换材料仍然以金属为主:不锈钢和钴基合金作为较早应用的生物医用金属植入物材料,具有生物相容性不足、诱导成骨能力差、易产生应力屏蔽效应等缺陷;钛及钛合金金属材料虽然生物相容性有所提高,但是钛合金与体液反应容易释放铝和钒等有毒离子,纯钛植入物的强度不足难以满足骨科植入物要求。
聚醚醚酮(PEEK)具有优良的力学性、耐磨性、耐热性、化学稳定性等优点,弹性模量接近自然骨,是一种适合长期植入人体的骨替代物材料。然而PEEK是惰性材料,与人体组织缺乏亲和力,因而无法实现植入物与相邻骨组织和软组织的生物连接,骨诱导性较差,不利于骨长入。
羟基磷灰石(HA)是一种常用的无毒无抗原性,同时兼具有良好生物活性、生物相容性和骨诱导性的生物组织材料,是极具前景的骨组织替代材料。纯HA的力学性能比较差,这大大限制了它在需要承受较大载荷骨关节替换中的应用。单一的HA与基体的结合强度不高,植入人体后,在体液的作用下容易脱落。因此加工注塑成型一种增加PEEK与HA相容性强且分散性好的PEEK复合材料更具意义。
