Description

一种钽支撑物
技术领域
本发明涉及一种医疗器械，特别是一种钽支撑物。
背景技术
现有技术中多孔钽支撑棒结构存在孔径和丝径比较单一，使用钽棒对骨股骨头坏死部位或者骨缺损部位进行填充，无法放置小碎骨于假体中，以致不能满足骨组织更好的长入和细胞的增殖。骨小梁丝径、孔径单一，不利于满足骨长入和软组织更好的长入和细胞的增殖，不能消除应力遮挡现象等问题；3D打印垫块属于微孔结构，孔径较小，术中不能植骨，骨长入效果相对较差；垫块假体相对较重；弹性模量高，术后易出现应力遮挡现象。
因此，当下急需一种高稳定性、骨长入效果好的钽支撑物。
发明内容
为解决上述技术问题，本发明提供一种钽支撑物，包括支撑物主体，所述支撑物主体为不规则形，且所述支撑物主体为多层结构，所述支撑物主体的孔隙为不规则性。
进一步的，所述支撑物主体的各层孔径、骨小梁直径及孔隙率均不同；
进一步的，所述支撑物主体的每层中的各骨小梁之间均为无断丝的连接结构，优选的外部骨小梁直径径为1mm-2mm；
进一步的，所述支撑物主体最外层孔径为5mm-10mm；
进一步的，所述支撑部主体最外层的骨小梁表面设有凹凸不平的毛刺结构，优选的所述毛刺结构的形状及排列方式可调整，从而增加整体结构的粗糙度。
进一步的，所述支撑部主体最外层的骨小梁设置有一个以上联通孔，优选的连通孔个数为1-3个，且连通孔直径优选0.2mm-0.3mm。
进一步的，连通孔间通过斜孔相互连接，联通孔与骨小梁外部也通过斜孔联通，斜孔直径优选0.1mm-0.2mm；优选的斜孔在丝径上不均匀排布，且分布于丝径截面的不同角度；通孔与斜孔用途在于通过虹吸效应，将营养成分输送到骨生产需要的位置。
进一步的，所述支撑物主体内部各层的骨小梁直径为0.3-0.8mm，孔径5mm-10mm，大孔利于将骨植入支撑物内部，并且提供一定的支撑；
所述支撑物主体采用3D打印制造，且材料为钽或钛。
本发明具有以下优点：
1、本技术中3D打印支撑物主体是根据患者的骨缺损部位定制的，可以使支撑物的形状和尺寸与患者的骨缺损匹配一致。
2、本技术中3D打印支撑物主体的多孔结构是不均匀的，更有利于不同的骨组织和细胞组织的长入，同时增加摩擦力，实现初期稳定性；
3、3D打印支撑物主体可以使碎骨更好的植入到支撑物的结构中，使骨组织和细胞组织与内部的碎骨实现良好的多方位的结合生长。
4、3D打印支撑物主体与传统的骨小梁结构不同。传统骨小梁分为均匀、非均匀(带毛刺)骨小梁，起到利于骨长入及初期稳定的作用。而本发明的骨小梁结构实在带毛刺的小梁基础上，横向、竖向方向上增加了孔隙，在保证小梁强度的基础上，既保留原有优势，提高成骨细胞的粘附、增值、分化能力，利于骨长入，摩擦力大，利于初期稳定性；互联互通性更高，使营养等物质可以运输的更加流畅，增加了代谢的场所面积，使骨长入进度更加迅速，骨长入效果更加牢靠。

具体实施方式
为使本领域技术人员更好地理解本发明的技术方案，下面结合附图和具体实施方式对本发明的一种钽支撑物作进一步的详细描述。
本发明提供一种钽支撑物，
包括支撑物主体1，所述支撑物主体为不规则形，诸如不规则球形、椭球形、生活中常见的马铃薯形状等，所述支撑物主体1为多层结构，支撑物主体的各骨小梁之间形成的孔隙为不规则性。支撑物主体的各层孔径、骨小梁直径及孔隙率均不同；
所述支撑物主体1的每层中的各骨小梁之间均为无断丝的连接结构，这样这增加了支撑物主体的强度，本实例中支撑物主体最外层的骨小梁直径径为1mm-2mm；支撑物主体1最外层孔径为5mm-10mm；
支撑部主体1最外层的骨小梁表面设有凹凸不平的毛刺2，为了增加整体的粗糙度，优选的所述毛刺结构的形状及排列方式可根据不同人员进行调整。
支撑部主体最外层的骨小梁设置有一个以上联通孔3，本实施例中的连通孔个数为1-3个，且连通孔直径优选0.2mm-0.3mm。
连通孔3间通过斜孔4相互连接，联通孔与骨小梁外部也通过斜孔联通，斜孔直径优选0.1mm-0.2mm；优选的斜孔在丝径上不均匀排布，且分布于丝径截面的不同角度；通孔与斜孔用途在于通过虹吸效应，将营养成分输送到骨生产需要的位置。支撑物主体内部各层的骨小梁直径为0.3-0.8mm，孔径5mm-10mm，大孔利于将骨植入支撑物内部，并且提供一定的支撑；
所述支撑物主体采用3D打印制造，且材料为钽或钛。
本发明具有以下优点：
1、本技术中3D打印支撑物主体是根据患者的骨缺损部位定制的，可以使支撑物的形状和尺寸与患者的骨缺损匹配一致。
2、本技术中3D打印支撑物主体的多孔结构是不均匀的，更有利于不同的骨组织和细胞组织的长入，同时增加摩擦力，实现初期稳定性；
3、3D打印支撑物主体可以使碎骨更好的植入到支撑物的结构中，使骨组织和细胞组织与内部的碎骨实现良好的多方位的结合生长。
4、3D打印支撑物主体与传统的骨小梁结构不同。传统骨小梁分为均匀、非均匀(带毛刺)骨小梁，起到利于骨长入及初期稳定的作用。而本发明的骨小梁结构实在带毛刺的小梁基础上，横向、竖向方向上增加了孔隙，在保证小梁强度的基础上，既保留原有优势，提高成骨细胞的粘附、增值、分化能力，利于骨长入，摩擦力大，利于初期稳定性；互联互通性更高，使营养等物质可以运输的更加流畅，增加了代谢的场所面积，使骨长入进度更加迅速，骨长入效果更加牢靠。
可以理解的是，以上实施方式仅仅是为了说明本发明的原理而采用的示例性实施方式，然而本发明并不局限于此。对于本领域内的普通技术人员而言，在不脱离本本发明的精神和实质的情况下，可以做出各种变型和改进，这些变型和改进也视为本发明的保护范围。
