Abstract

本发明是关于一种人体植入物，其设有至少一亲骨结合件及至少一主载件；该至少一亲骨结合件为由3D打印所制成的金属构件，并具有至少一结合部、至少一隔离件及一骨细胞增生部，该至少一结合部为多孔结构，该至少一隔离件设于该至少一结合部的一侧，该骨细胞增生部设于该至少一隔离件的一侧，使人体的骨细胞能在该骨细胞增生部中增生；该至少一主载件为由医用高分子材料所制成的构件，并结合于该至少一结合部；借以提供一种提升骨融合程度、具有与人体骨骼相近的弹性模数、各构件紧密结合而不易相分离，且寿命较长的人体植入物。

Description

人体植入物
技术领域
本发明涉及一种人体植入物，尤指一种能提升骨融合程度、具有与人体骨骼相近的弹性模数、无疲劳应力问题、无论于各方向上受力该结合部与该主载件的形变量相近、各构件紧密结合而不易相分离，且使用寿命长的人体植入物。
背景技术
现有人体植入物如椎间融合装置，或是骨板、下颚骨及人工牙根等骨科植入物主要包括至少一主载件、至少一亲骨结合件及至少一固定栓。该至少一主载件由医用高分子材料所制成，其中医用高分子材料的弹性模数接近于人体骨头的弹性模数，使该至少一主载件的强度更接近人体骨头强度。该至少一亲骨结合件则由具有生物兼容性的金属材料所制成，且该至少一亲骨结合件能诱发骨细胞于其中增生，最终与其相融合。该至少一主载件及该至少一亲骨结合件通过该至少一固定栓相结合，而组成现有人体植入物。
然而，现有人体植入物具有以下缺点：
1.由于该至少一亲骨结合件由金属材料所制成，而金属材料的弹性模数高于医用高分子材料的弹性模数，该至少一亲骨结合件与该至少一主载件结合后容易产生疲劳应力的问题。
2.为了将该至少一亲骨结合件与该至少一主载件相结合，该至少一亲骨结合件与该至少一主载件间必然要通过如该至少一固定栓的锁固件，以将该至少一亲骨结合件与该至少一主载件相结合，否则现有人体植入物在被植入人体后容易因受力而相分离。
3.呈第2点所述，无论现有人体植入物作为椎间融合装置、骨板或是下颚骨使用，长期使用后，该至少一固定栓容易由该至少一主载件及该至少一亲骨结合件脱落。如此一来，不仅导致该至少一固定栓留存于人体内部，该至少一主载件及该至少一亲骨结合件亦会相分离而失去其原有功效。
综上所述，现有人体植入物诚有其缺陷及不足。
发明内容
本发明的目的是为解决现有人体植入物因为金属材料的弹性模数高于医用高分子材料的弹性模数而容易产生疲劳应力的问题，以及需要通过该至少一固定栓结合该至少一主载件及该至少一亲骨结合件，若该至少一固定栓脱落会导致该至少一固定栓留存于人体内部，更会导致该至少一主载件与该至少一亲骨结合件相分离而失去原有功效等缺失。
为达到上述目的，本发明提供了一种人体植入物，其包括：
至少一亲骨结合件，该至少一亲骨结合件为由3D打印所制成的金属构件，并具有至少一结合部、至少一隔离件及一骨细胞增生部，该至少一结合部为多孔结构，该至少一隔离件设于该至少一结合部的一侧，该骨细胞增生部设于该至少一隔离件的远离该至少一结合部的一侧，人体的骨细胞能在该骨细胞增生部中增生；以及
至少一主载件，该至少一主载件为由医用高分子材料所制成的构件，并结合于为多孔结构的该至少一结合部，使该至少一主载件能与该至少一亲骨结合件相结合。
进一步，上述人体植入物，其中，该至少一亲骨结合件的该骨细胞增生部为多孔结构。
再进一步，上述人体植入物，其中，该至少一亲骨结合件的该骨细胞增生部具有粗糙表面。
更进一步，上述人体植入物，其中，该至少一结合部包括一个以上的链接单元，各该链接单元包括有多个链接件，各链接件为能使该至少一结合部的弹性模数被调整的曲线构件。
更进一步，上述人体植入物，其中，该人体植入物具有两所述亲骨结合件，两该亲骨结合件分别结合于该至少一主载件的两侧，且该至少一主载件与各该亲骨结合件的该至少一结合部相结合。
更进一步，上述人体植入物，其中，该至少一亲骨结合件的该至少一隔离件具有一基板，该基板设于该至少一结合部与该骨细胞增生部之间。
更进一步，上述人体植入物，其中，该至少一亲骨结合件的该至少一隔离件具有一侧向包覆部，该侧向包覆部由该基板延伸，并包覆该骨细胞增生部的外周缘。
更进一步，上述人体植入物，其中，该侧向包覆部包括两侧板，两该侧板设于该基板相远离的两侧，使该侧向包覆部局部包覆该骨细胞增生部的外周缘。
更进一步，上述人体植入物，其中，该侧向包覆部呈环形，使该侧向包覆部完整包覆该骨细胞增生部的外周缘。
更进一步，上述人体植入物，其中，该至少一隔离件的该基板为实心结构。
更进一步，上述人体植入物，其中，该至少一隔离件的该基板为该医用高分子材料无法通过的多孔结构。
更进一步，上述人体植入物，其中，该至少一亲骨结合件具有两所述隔离件及两所述结合部，两该隔离件分别设于该骨细胞增生部的两侧，两该结合部分别与两该隔离件相结合，各该结合部设于对应的隔离件的远离该骨细胞增生部的一侧；该人体植入物具有两该主载件，两该主载件分别与两该结合部相结合，各该主载件结合于该至少一亲骨结合件的对应的该结合部的远离对应的该隔离件的一侧。
更进一步，上述人体植入物，其中，该至少一亲骨结合件的该至少一结合部与该主载件的交界处为平面。
更进一步，上述人体植入物，其中，该亲骨结合件为一环形柱体，该结合部位于该亲骨结合件的中央，该隔离件环形包覆该结合部的其中一段，而使该隔离件设于该结合部的一侧，该骨细胞增生部环形包覆该隔离件，使该骨细胞增生部设于该隔离件的远离该结合部的一侧，该骨细胞增生部的表面为一粗糙面；该主载件与该亲骨结合件的该结合部相结合，且该主载件环形包覆该结合部异于该隔离件的一段。
通过上述的技术手段，本发明所获得的功效有：
1.本发明的各亲骨结合件的该骨细胞增生部为利用近年来日益成熟的3D打印技术所制成的多孔结构，或是将该骨细胞增生部的表面制成粗糙面，有利于骨细胞在该骨细胞增生部中增生，而能提升本发明被植入人体后与相邻骨头的骨融合程度，因此本发明作为椎间融合装置使用时不易产生沉陷的问题。
2.本发明将该结合部制成多孔结构，避免各亲骨结合件的该结合部因为是由金属材质所制成，致使其因为弹性模数与医用高分子材料的弹性模数的差距，导致其容易与该主载件相分离以及疲劳应力的问题。
3.相对现有人体植入物的该至少一亲骨结合件与该至少一主载件要通过该至少一固定栓相结合，本发明的各亲骨结合件的该结合部为通过3D打印技术所制成的多孔结构，配合射出成型技术或是灌铸成型技术，使该主载件的原料渗透至该结合部的多个该穿孔中，待原料固化后，该主载件即可结合于各亲骨结合件的该结合部，因此该主载件与各亲骨结合件间不必通过任何锁固件即可紧密结合。
4.呈第3点所述，利用3D打印技术配合射出成型技术或是灌铸成型技术所制成的本发明的该主载件与各亲骨结合件间的密合度相对现有人体植入物的各构件高，该主载件与各亲骨结合件不仅不容易相分离，而能延长本发明的寿命，还能避免如现有人体植入物会导致锁固件脱落后留存于人体内部的缺失。
5.该骨细胞增生部为多孔结构或是表面为粗糙面的结构，能降低各亲骨结合件所能承受的力量，借以避免邻近椎节退化。
6.各亲骨结合件的该结合部略呈一方形，使该结合部与该主载件的交界处均为平面，而能避免应力集中的问题，进而能避免长期使用后该主载件与各亲骨结合件相分离的问题。

具体实施方式
以下配合附图及本发明的较佳实施例，进一步阐述本发明为达成预定发明目的所采取的技术手段。
本发明所提出的人体植入物的第一较佳实施例如图1、图4及图5所示，其被作为一椎间融合装置使用，并包括两亲骨结合件10及一主载件20，其中：
如图1、图4及图5所示，两该亲骨结合件10间隔并朝向相反的方向设置。如图1及图2所示，各亲骨结合件10为由3D打印所制成的金属构件，并具有一结合部11、一隔离件12及一骨细胞增生部13。如图1至图3所示，该结合部11为多孔结构，且该结合部11略呈一方形，并具有多个穿孔111，各穿孔111形成于该结合部11的表面及内部。再进一步，该结合部11可为由如中国台湾专利公开号第201946769号所揭露的“可调整弹性模数的基层结构”所构成，该可调整弹性模数的基层结构包括一个以上的链接单元，如图6所示，各链接单元包括有多个链接件112，各连结件112为一S形状且扭转延伸的曲线构件，该连结件112的扭转角度及延伸方向能调整而得到不同方向的支撑强度，使该结合部11的弹性模数能被调整。该隔离件12设于该结合部11的远离另一亲骨结合件10的一侧，且具有一基板121及一侧向包覆部122；该基板121设于该结合部11的远离另一亲骨结合件10的一面；该侧向包覆部122由该基板121朝远离该结合部11的方向延伸；于该第一较佳实施例中，该侧向包覆部122包括两侧板，两该侧板设于该基板121相远离的两侧。该骨细胞增生部13设于该隔离件12的该基板121的远离该结合部11的一侧，使该基板121设于该结合部11与该骨细胞增生部13之间，该侧向包覆部122通过两该侧板局部包覆该骨细胞增生部13的外周缘，该隔离件12将该结合部11及该骨细胞增生部13隔开；进一步，该基板121可为实心结构，亦可为致密的多孔结构。该骨细胞增生部13为多孔结构，使骨细胞能在其中增生，而有利于本发明被植入椎间后，与相邻的椎体进行骨融合，借以提高本发明被植入脊椎后的稳定性，而能降低本发明被植入脊椎后沉陷的可能性；再进一步，该骨细胞增生部13的表面亦可为一粗糙面，使骨细胞能在该骨细胞增生部13上增生。
进一步，各亲骨结合件10为由钛金属所制成的构件，钛金属具有高抗拉强度、耐腐蚀性以及生物兼容性，有利于骨细胞于该骨细胞增生部13中增生，更能使血管***形成于其中。较佳的是，如图1及图2所示，各亲骨结合件10具有至少一卡合件14，该卡合件14设于该骨细胞增生部13的远离另一亲骨结合件10的一面，该卡合件14具有一斜面，在本发明被植入脊椎后，该卡合件14能提高本发明与相邻椎体间的摩擦力，而能提高本发明被植入椎间后的稳定性，该卡合件14可为实心结构，亦可为多孔结构，若该卡合件14为多孔结构，骨细胞可在该卡合件14内部增生，较佳的是，各亲骨结合件10设有四个卡合件14，四个该卡合件14间隔设于该骨细胞增生部13上，其中两个卡合件14邻近该隔离件12的其中一侧板，另外两个卡合件14邻近该隔离件12的另一侧板。
如图1、图4及图5所示，该主载件20为由医用高分子材料所制成的构件。该第一较佳实施例的制作方式，是先将该两亲骨结合件10放置于一模具中，并使各亲骨结合件10的该骨细胞增生部13朝向外侧，再以射出成型的方式将该主载件20的原料射出至该模具内，使原料渗透至该结合部11的多个该穿孔111中内，待原料固化后，该主载件20即可结合于各亲骨结合件10的该结合部11，使该主载件20与两该亲骨结合件10相结合，并使两该亲骨结合件10分别结合于该主载件20的两侧。于制作过程中，若该基板121为实心结构，该医用高分子材料无法渗入其中；若该基板121为致密的多孔结构，该基板121致密的程度使该医用高分子材料无法通过该基板121。该主载件20设有一头部21及一尾部22；该头部21呈圆锥状；该尾部22形成于该主载件20的与该头部21的位置相对的一端，并设有一螺孔221；本发明于使用时，是将一手术器械螺合于该螺孔221，借以固持本发明，再将该头部21对正椎间，即可植入本发明，其中各亲骨结合件10的该卡合件14卡抵于相邻锥体，可提高本发明与相邻椎体间的摩擦力，借以降低本发明被植入椎间后位移的机会。进一步，该主载件20为由聚醚醚酮(PEEK)、PAEK(聚芳醚酮)或是超高分子量聚乙烯(UHMWPE)等医用高分子材料所制成的构件，其中医用高分子材料的弹性模数与椎体骨骼的弹性模数相接近，在本发明被植入椎间后，能避免邻近椎节退化的问题。
进一步，该主载件20亦可以灌铸成型的方式结合于各亲骨结合件10的该结合部11，使该主载件20与该两亲骨结合件10相结合。其中，灌铸成型的技术与现有铸造技术相同。
各亲骨结合件10的该结合部11为多孔结构，使该主载件20的原料在尚未成形前渗透至该结合部11中，待该原料固化为该主载件20后，该主载件20能够牢固地与各亲骨结合件10相结合而不易分离。如图4及图5所示，进一步，各亲骨结合件10的该结合部11略呈一方形，使该结合部11与该主载件20的交界处均为平面，而能有效避免应力集中的问题，借以避免长期使用后该主载件20与各亲骨结合件10相分离的问题。该骨细胞增生部13为多孔结构或是表面为粗糙面的结构，除了可让骨细胞在内部增生之外，更能降低各亲骨结合件10所能承受的力量，借以避免邻近椎节退化的问题。
本发明所提出的人体植入物的第二较佳实施例如图7所示，该第二较佳实施例与该第一较佳实施例的差异在于：该第二较佳实施例的各亲骨结合件10的该隔离件12的该侧向包覆部122A呈环形，使该侧向包覆部122A完整包覆该骨细胞增生部13的外周缘。
本发明所提出的人体植入物的第三较佳实施例如图8所示，该第三较佳实施例与该第一较佳实施例的差异在于：各亲骨结合件10的该隔离件12不具有该侧向包覆部122，且该基板121将该骨细胞增生部13及该主载件20隔离。
本发明所提出的人体植入物的第四较佳实施例如图9所示，该第四较佳实施例与该第一较佳实施例的差异在于：各亲骨结合件10的该隔离件12不具有该侧向包覆部122，该主载件20邻近该头部21的一端延伸至与各亲骨结合件10的该骨细胞增生部13的外表面相齐平处。
本发明所提出的人体植入物的第五较佳实施例如图10所示，该第五较佳实施例与该第一较佳实施例的差异在于：各亲骨结合件10的该隔离件12不具有该侧向包覆部122，该主载件20邻近该尾部22的一端延伸至与各亲骨结合件10的该骨细胞增生部13的外表面相齐平处。
本发明所提出的人体植入物的第六较佳实施例如图11所示，该第六较佳实施例与该第一较佳实施例的差异在于：该第六较佳实施例是作为一骨板使用，且该第六较佳实施例仅包括一亲骨结合件10。该主载件20结合于该亲骨结合件10的该结合部11。于使用时，该亲骨结合件10的该骨细胞增生部13贴靠于骨折处，骨细胞在该骨细胞增生部13内增生后，本发明即可逐渐与骨头相融合。
本发明所提出的人体植入物的第七较佳实施例如图12所示，该第七较佳实施例与该第一较佳实施例的差异在于：该第七较佳实施例是作为一下颚骨使用，并具有两主载件20，且仅具有一亲骨结合件10。该亲骨结合件10具有一曲率，并具有一骨细胞增生部13、两隔离件12及两结合部11；该骨细胞增生部13具有一曲率；该两隔离件12分别设于该骨细胞增生部13的两侧，各结合部11设于其中一隔离件12的远离该骨细胞增生部13的一侧，即每个隔离件12的远离该骨细胞增生部13的一侧设有一结合部11。各主载件20结合于该亲骨结合件10的其中一结合部11的远离对应隔离件12的一侧，即每个结合部11的远离与其对应的隔离件12的一侧设有一主载件20。由于各主载件20为由医用高分子材料所制成的构件，因此能避免由金属材质制成的该亲骨结合件10与相邻的骨头及肌肉直接接触而相磨耗。进一步，由于该两结合部11及该骨细胞增生部13均为多孔结构，而能减轻该第七较佳实施例作为下颚骨使用的重量。
本发明所提出的人体植入物的第八佳实施例如图13所示，该第八较佳实施例是作为一人工牙根使用，且仅具有一亲骨结合件10。该亲骨结合件10为一环形柱体；该结合部11位于该亲骨结合件10的中央，并具有多个穿孔111，各穿孔111形成于该结合部11的表面及内部；该隔离件12环形包覆该结合部11的其中一段，而设于该结合部11的一侧，且该隔离件12与该结合部11之间具有间隙；该骨细胞增生部13环形包覆该隔离件12，使该骨细胞增生部13设于该隔离件12的远离该结合部11的一侧，该骨细胞增生部13的表面设有一螺纹，且该骨细胞增生部13的表面为一粗糙面，供骨细胞于其中增生。该主载件20与该亲骨结合件10的该结合部11相结合，并布满该隔离件12与该结合部11之间的间隙以及该结合部11的多个该穿孔111，且该主载件20环形包覆该结合部11未被该隔离件12包覆的一段。该第八较佳实施例被该骨细胞增生部13包覆的部分植入牙床骨中，使骨细胞能在该骨细胞增生部13的表面增生，该第八较佳实施例被该主载件20包覆的部分则局部露出于牙龈外，而能与一牙冠相结合。
于本发明的第一较佳实施例至第八较佳实施例中，各亲骨结合件10的该结合部11及该骨细胞增生部13均为多孔结构，如此的多孔结构是难以用传统工法制成的，通过近年来日益兴盛的3D打印技术制成各亲骨结合件10，再配合射出成型技术或是灌铸成型技术，使该主载件20紧密结合于各亲骨结合件10的该结合部11，而达到异材质紧密结合的功效，是为本发明的重要技术特征，且该骨细胞增生部13的孔隙可配合使用人的健康状况、年龄、生活习惯及应用部位调整。于该第八较佳实施例中，该骨细胞增生部13则非多孔结构，该骨细胞增生部13的表面为粗糙面，使骨细胞于其中增生。
通过上述的技术手段，本发明所获得的功效增进有：
1.本发明的各亲骨结合件10的该骨细胞增生部13为利用近年来日益成熟的3D打印技术所制成的多孔结构，或是将该骨细胞增生部13的表面制成粗糙面，有利于骨细胞在该骨细胞增生部13中增生，而能提升本发明被植入人体后与相邻骨头的骨融合程度，因此本发明作为椎间融合装置使用时不易产生沉陷的问题。
2.本发明将该结合部11制成多孔结构，避免各亲骨结合件10的该结合部11因为是由金属材质所制成，致使其因为弹性模数与医用高分子材料的弹性模数的差距，导致其容易与该主载件20相分离以及疲劳应力的问题。
3.相对现有人体植入物的该至少一亲骨结合件与该至少一主载件要通过该至少一固定栓相结合，本发明的各亲骨结合件10的该结合部11为通过3D打印技术所制成的多孔结构，配合射出成型技术或是灌铸成型技术，使该主载件20的原料渗透至该结合部11的多个该穿孔111中，待原料固化后，该主载件20即可结合于各亲骨结合件10的该结合部11，因此该主载件20与各亲骨结合件10间不必通过任何锁固件即可紧密结合。
4.呈第3点所述，利用3D打印技术配合射出成型技术或是灌铸成型技术所制成的本发明的该主载件20与各亲骨结合件10间的密合度相对现有人体植入物的各构件高，该主载件20与各亲骨结合件10不仅不容易相分离，而能延长本发明的寿命，还能避免如现有人体植入物会导致锁固件脱落后留存于人体内部的缺失。
5.该骨细胞增生部13为多孔结构或是表面为粗糙面的结构，能降低各亲骨结合件10所能承受的力量，借以避免邻近椎节退化的问题。
6.各亲骨结合件10的该结合部11略呈一方形，使该结合部11与该主载件20的交界处均为平面，而能避免应力集中的问题，进而能避免长期使用后该主载件20与各亲骨结合件10相分离的问题。
以上所述仅是本发明的较佳实施例而已，并非对本发明做任何形式上的限制，虽然本发明已以较佳实施例揭露如上，然而并非用以限定本发明，任何熟悉本专业的技术人员，在不脱离本发明技术方案的范围内，当可利用上述揭示的技术内容作出些许更动或修饰为等同变化的等效实施例，但凡是未脱离本发明技术方案的内容，依据本发明的技术实质对以上实施例所作的任何简单修改、等同变化与修饰，均仍属于本发明技术方案的范围内。
