Description
技术领域
本发明涉及医疗器械技术领域,尤其涉及骨缺损人工修复体。
背景技术
创伤、感染、肿瘤、先天性畸形和人工关节翻修等造成的骨缺损,均需要骨及其替代材料修复。异体骨及异种骨来源有限、价格昂贵,且有抗原消除不彻底及传播艾滋病等传染病的缺点;自体骨移植有增加手术创伤及供骨区疼痛、感染的弊端。
骨替代材料避免了生物源性修复材料的缺点,且具有优良的生物相容性和力学性能,用于填充缺损部位,起到支撑及引导细胞、血管及骨组织长入并生长的作用,或诱导骨前体细胞分化形成新骨的作用,因此越来越受到骨科医生的青睐。
生物陶瓷(bioactive ceramics)因其良好的生物相容性和生物活性,已广泛应用于骨修复领域,如组织工程;骨骼和牙周缺损的修复重建;金属内植物表面生物活性涂层等。羟基磷灰石、磷酸钙具良好的成骨能力。
石墨烯(Graphene)是一碳原子以sp2杂化轨道呈蜂巢晶格(honeycomb crystallattice)排列构成的单层二维晶体。具有优异的光学、电学、力学特性。强度最高的物质>钢铁200倍,杨氏模量约1TPA=150,000,000psi。
氧化石墨烯(graphene oxide)是石墨烯的氧化物,是目前最常用的一种,具有一下优点:
1,抗菌作用----抑制大肠杆菌的生长;
2,抗癌治疗----辨识癌细胞与正常细胞电子密度不同;
3,成骨作用----增强成骨细胞代谢和增强成骨细胞增殖能力。
发明内容
本发明旨在提供骨缺损人工修复体,具有良好的初始稳定性和成骨能力。
为达到上述目的,本发明采用的技术方案如下:
骨缺损人工修复体,包括假体干和骨修复生长因子层,所述假体干为多孔结构,至少在假体干的部分外表面设有骨修复生长因子层,骨修复生长因子层材质包括氧化石墨烯和/或磷酸钙陶瓷。
优选地,磷酸钙陶瓷为HA磷酸钙陶瓷。
进一步优选地,骨修复生长因子层为混合涂层,混合涂层为氧化石墨烯层和磷酸钙陶瓷层。
或者,氧化石墨烯层和磷酸钙陶瓷层由内而外依次设置。
或者,磷酸钙陶瓷层和氧化石墨烯层由内而外依次设置。
或者,骨修复生长因子层的材质为氧化石墨烯和磷酸钙陶瓷的混合物。
进一步的,假体干包括主体段和主体段两端的固定段,所述骨修复生长因子层设于主体段外表面,主体段和固定段一体制造。
进一步的,固定段上设有固定孔。
优选地,假体干的材质为钛。
进一步的,骨缺损人工修复体由3D打印制得。
与现有技术相比,本发明具有以下有益效果:
本发明具有良好的初始稳定性和优异的成骨能力,长期修复效果好,采用3D打印能够根据实际情况精准设计,完美匹配,可解决临床上节段性骨缺损修复面临的诸多难题。

图1是实施例一的三维图;
图2是实施例一的剖视图;
图3是实施例二的结构示意图;
图4是实施例三的结构示意图;
图5是实施例四的结构示意图;
图中:1-固定段、2-主体段、3-固定孔、4-骨修复生长因子层、41氧化石墨烯层、42-磷酸钙陶瓷层。
具体实施方式
为了使本发明的目的、技术方案及优点更加清楚明白,以下结合附图,对本发明进行进一步详细说明。
实施例一
