Abstract
两块椎骨的融合是脊椎手术中最常见的方式之一。本发明涉及一种包括多个平行板的脊椎植入体。在这些板中有意制作的轮廓允许产生有利于生物力学的功能和调节选择,这些不可能用其他方式提供或费用很高。锚定元件的弹性使得本发明所公开的植入体能够被调节到骨的端板,因此获得均匀的力分布并防止发生挤压或端板压迫骨折。该板的结构允许所使用的生产方法中可以产生钩状凹槽轮廓,并因此使得植入体被牢固锚定在骨头中而不会对其造成损坏。而且,这些板可以通过致动器连接以使其高度和/或角度位置能被调节,因而使椎间盘间隙可以被垂直和物理性的调节。该垂直调节可以沿着植入体的长度改变以使该段的角度也能被调节。如果将这些板通过偏心轴相互连接,那么这套板子所进行的垂直和平移的组合运动也能被用于对两块椎骨进行平移而重新定位。
Description
技术领域
本发明涉及一种被插入到两个椎骨的椎间隙以稳定脊椎的医学植入体。根据本发明的植入体的基本特征是所述的植入体由多个薄板组成,从而允许进一步获得制造、植入及体内功能的优越性能。
背景技术
脊椎发生病变时,常常需要稳定一段或几段的脊椎。因此,现在市场上具有多种椎骨间移植物(也称为“椎间融合器”),其目的是使一部分脊椎产生骨性融合。这类椎间融合器的植入与许多复杂因素相关。例如,由于施加局部应力或由于放置植入体的区域小会引起发生端板压迫骨折,由于应力遮蔽不会成功实现预期的骨性融合,植入体发生脱位,或椎体相对于彼此的位置没有被完全矫正。而且,常常需要提供另一种的支撑功能(例如,通过椎弓根螺钉-杆系统方式)稳定该段以确保这些植入体不会发生任何移位。
1993年的WO9501763A1公开了一种脊柱植入体,它由具有中心开口的篮形环构成,中心开口用于容纳骨材料。2005年的EP1800627A2特别指出,为了增大接触面积,脊椎植入体系统可由两个或多个环构成以降低椎骨端板发生压迫骨折。2000年的WO0234171A2公开了可变形的聚合物条状物,将它们插入到椎间隙并相对于负荷方向排列。
2004年的US6767738B1和2006年的WO2008079953A2分别提出了一种具有两个或三个刚性连接板的装置,由于板子之间的距离,使得该装置具有适于插入骨移植材料、骨移植替代材料或骨形态生成蛋白(BMP)的空间。在这种情况下,板子具有容器的功能,用于将机械不稳定的骨移植材料插入椎间隙并阻止在椎间盘间隙和/或椎体内发生任何不希望的分布。由于所需要的功能和由于板子的数量少,没有设计出可用于确定大量板子之间的间隙的可用的制品。另一个缺点是填充所述间隙的骨移植材料必须充足和/或必须提供并导入其他的骨移植替代材料。
1998年的WO0045747A1和1999年的WO0040177A1教导由骨移植材料构成的层状装置。
上述参考的在先发明都包括或允许将骨移植或骨移植替代材料插入椎间隙中;然而,它们不能矫正错位的椎骨位置(角度和偏移),也不能提供在椎体端板上获得使负载平均分布的方法。由于植入体的高度是无法调节的,因此在植入过程中,在某种程度上需要施加较大的植入力并(尽量)撑开端板。
1999年的WO0044319A1公开了一种可扩展的脊椎植入体。大量的折叠元件通过小的锥间盘通路被插入,并通过压挤使之直立以撑开椎骨。此外,1998年的DE19816832C1和2008年的US2010010633A1教导的脊椎植入体具有至少一个轴,轴上具有偏心安装在其上的圆盘。所述的轴可以转动以使圆盘延伸并且植入体的架构高度增长。这种方案潜在的缺点是需要在轴和圆盘之间具有刚性连接。而且,这些脊椎植入体只限于支架方面的应用,其中不能完全阻止椎骨彼此之间的移位的发生,这是由于可转动的轴和在圆盘和端板之间产生的摩擦造成的。临床试验已经表明,由于绝大部分圆柱形的横截面,很多这种植入体导致端板压迫骨折,并且从某种程度上来说这些问题难于解决。
2007年的US2010016968A1和2005年的WO2007048012A2公开了对滑脱的椎骨重新定位的方法和植入体。为此,两个被植入的部分相对彼此发生移动直到到达最终的位置。其中,这些附件是基于暂时被植入的装置,在最终治疗后这些装置必须再被移走。
除了上述的各种不足,现有的植入体没有一种含有任何齿状物,或者,即使含有,也仅仅是在骨接触表面上具有简单的齿状物以提高对移位的抵抗。在本领域中机械加工具有被限定的齿的几何形状(包括切口)是未知的,这是由于目前使用至今的结构和制造种类决定的。当使用骨移植材料作为植入材料时,这些材料的牢固性较低,阻止了这种齿状几何形状的制造和应用。
发明内容
发明目的
本发明的目的是希望提供一种通过椎间隙稳定脊椎的植入体。根据本发明的植入体的主要作用包括在尽可能大的接触面积上平均分布载荷,且简单而牢固地锚定在接触表面上,而不会使其机械性能变弱。此外,可选的实施方案通过微移动植入体结构对骨组织加入生长刺激,在原位调整植入体的高度和角度,并矫正平移,免除将骨移植或骨移植替代材料填充植入体的需要。此外,根据本发明的植入体制造成本低并简化了手术中的操作。
技术方案
本发明的目的是通过提供由多个板子构成的脊椎植入体实现的,所述的板子基本上以平行的方式排列在一或两个平面上。在骨头的这一侧,板子可以具有精细轮廓,其中齿状结构内的切口允许进一步增加端板内锚定作用的牢固性。通过在板子上和/或板子内有目的使用其它轮廓和/或结构,植入体可以产生不同的、可选的功能。并将它们互相组合起来。例如,板子的某些区域具有弹性性能并因此能够自身调整到端板轮廓,和/或因此抵消应力遮蔽。再者,调整刚度以使它与骨头的刚度对应,并将拉伸刺激传送到周围组织。在组合方面,板子可以与具有调整机构的致动器组合,调整机构可通过例如偏心轴,机械的,电的,或通过基于形状记忆性能的机构运行,并与该能力结合以执行相对运动以便于例如撑开椎间盘室或重新固定两个椎骨的相对位置。
仅使用以平行方式排列的具有薄壁强度的板可以降低所需的制造成本,以及从某种程度上来说复杂的结构。其中的轮廓优选通过光化学蚀刻方法获得或通过富集能量的射线(例如激光,电子束)和/或水射流从板中切割出来。而且,可以通过电腐蚀或注模(由金属或塑料材料)完全或部分制作轮廓。
有益效果
有益的是,由于所述的特定的齿状结构,本发明的植入体对基板以及端板的移位和压迫骨折具有非常高的抵抗力。这样产生了非常高的初期稳定性,从而避免在病人体内通过腹板或背棒系统的任何附加的稳定。由于获得有多个通道和/或格子结构和由于齿的弹性支持和/或通过有利的凹槽调整了植入体的刚度,还产生了巨大的刺激用于形成新的骨组织,特别是不需要用附加的骨移植或骨移植替代材料填充植入体。由于存在各种调整的可能性,一方面可以在病人的骨骼上实现装置的最佳调整,另一方面,简化了在那些放入植入体后被分开或角度调整的实施例中的植入体。另一个变体还介绍了通过整合到植入体中的某个功能来简单矫正椎体的AP排列的可能性。

具体实施方式
下面描述的技术方案通常以举例的方式加以说明。下面的描述必须理解成是对内在的思想的解释,而不是限定到每一个具体的示例。现在详细描述的实施例构成了本发明的组合基础,意指这些实施例可单独或组合起来实施。
根据本发明的植入体2被插入到两个椎骨1的椎间隙以稳定脊椎(图1)。在植入体和相邻的椎骨1的端板101之间产生至少一个接触表面。脊椎植入体2包括多个借助至少一个连接元件23相连的板21以及位于这些板之间的间隙22(图2)。板(21,210)具有0.05到3mm的壁厚,特别是在0.2至1.5mm之间。间隙22的宽度定向为骨头的小梁结构的大小,也在0.05和3mm之间,优选0.2和1.5mm之间。为了构造毛细管和/或为了提高牢固性,这些板也可以无间隙放置。如果对应的切口213和/或构造的用作毛细管的管道可以获得骨整合,在这种特殊的情况下,可以不提供间隙(距离=0mm)。
这些板可以(例如通过注射成型)由金属(金属注射成型),塑料或另一种生物相容的和/或其他的生物可吸收的材料或所述的这些材料的组合制成。生产板的其他特定的有利制造方法是在富集能量的射线(电子束,激光束,水射流)的辅助下的切割法或通过光化学蚀刻法由金属带、金属片或板子(光蚀刻)蚀刻。所提到的制造方法提供了设计板的多种可能性,并允许以低成本方式将各种功能整合到植入体中,这种植入体是不能被现有的由一个或两个部分构成的基本是一体的具体方式实施。例如,可以容易的将结构、形状、导向装置、开口和不同深度的齿状结构整合于板中,可以容易地产生具有凹槽的齿状结构或相对于下一个板子分别错位放置齿。相应的,骨接触表面能够(例如通过多个小的分支2121)来提供端板101的所谓的微穿透,其中所述的分支可以是凹槽2122,从而允许在很短的治疗时间后就已经获得骨的初期稳定的锚定稳定性,并且锚定连接的牢固性明显增长,特别是当承受拉应力时。由于板子的结构和相关的可能的制造方法,可以制作半渗透的孔、毛细管或开口213,它们激发植入体内部产生渗透压。渗透压反过来可用于支持代谢和细胞分化。为了以骨引导或/和骨诱导的方式构造板子的表面,可以提供具有合适材料的涂层的板子或将其制作成具有限定的粗糙度的板子。此外,可以对所有的或单个的板子的材料进行选择以使材料随着时间被吸收。为了获得长时间的限定的吸收,生产的板子具有不同的厚度和/或由具有不同吸收率的不同材料组成是有利的。
在另一个实施例3中,将板子设计成它们能够彼此互相插入(图3)。可以这样实现,使板子31和/或32包括槽型连接开口311,它们分别彼此相容并刚性连接。连接板子32中的各个槽311的距离限定了间隙22的间隔和距离。
在本发明的第三个实施例4中,在图4中以示例性的方式表示出板子41的动态结构。这就是植入体能够自身调整到端板101轮廓的原因,从而允许力在端板上均匀分布,而不会发生由于局部受力和拉伸集中造成的端板压迫骨折。其中板子410可以被构造为:构成骨连接表面的每个钩状部分和齿结构412被以弹簧式支撑,例如通过蜿蜒型的轮廓部分413。
图4中显示了另一个实施例420。在此显示的是如何通过多于一个的钩状元件422产生骨连接表面的弹簧式支撑,其中轮廓切口423被构造得更大。此外,板子430的弹簧型支撑连接用于获得弹性或降低植入体的整体刚度。这可以通过在连接开口431设置相邻的轮廓切口433来实现,这样允许在连接和/或调整开口431的负荷转移表面区域内具有弹性柔韧性。
此外,图4显示出适于容纳连接元件(42,23,5051,5052,5053,等)的不同形状的切口411,421,431,这些连接元件相对于板子41尽可能以垂直方式放置。连接元件可以被构造成螺丝,销,管,或轴,具有圆形,椭圆形,矩形或多边形的横截面。板形的连接元件32,42有利于对板子之间的间隙22进行一定距离的目标调整。其中板子的距离优选是与骨小梁的结构大小相容的,即约0.02至3mm,特别是0.2和1.5mm之间。用于调整间隙22的距离的另一种选择是沿着其中的轴线使连接元件的横截面(42,5051,5052,5053,等)逐渐变化和使板子41的连接开口421,431逐渐变化。然而,对于大量的板子,使用圆盘(5020,图10),环形或类似的元件具有优势,其厚度与间隙22的预期距离相对应。为此,将垫片5020分别置入板子41之间的连接元件(23,5051,5052,5053,等)上。最后,板子41之间的空间偏移压印有利于进行板子之间限定距离22的调整。
根据手术中各个病人的不同情况,可以将植入体设计成板子21,连接元件(23和/或32),以及(如果需要)分离的间隔盘或环5020的组件。这可以通过将一种装置插入含有可调节的或可变形的区域的椎间盘室内来实现,通过该装置可以检测或临时性复制端板轮廓。随后从椎间盘室内再次移走所述装置,这样就可以在手术中使用对应于该端板轮廓的不同高度和宽度的各个板子21来组装脊椎植入体。
第四个实施例5a介绍了本发明的一种植入体,它具有可调的高度(图5)。将该脊椎植入体5a插入椎间隙时,包括上板501和下板502的组合板起初具有最小高度,其中齿状结构5019和5028被平面5018、5029覆盖,从而使得植入体的插入更容易。在高度调整完成之后,其中组合板501和502彼此移位,使齿状结构5019和5028从平面5018,5029突出并进入端板101,充当其中的锚。将板子501和502构造成具有不同的连接孔。将用于支撑的开口(5011,5013,5021和5023)的方位和用于实现板子相对运动的开口5012和5022的方位区别设置。开口5011、5013的方向与开口5021、5023的方位不同,以实现组合板501和502之间的相对运动,特别地,在一个优选实施例中为旋转90°。在该实施例中,板子501和502通过两个轴5051和5053被支撑。板子的相对运动通过致动器发生,例如通过偏心轴5052和与其连接的用于传输旋转运动的装置具体实施。偏心轴5052的转动导致切口5012进而组合板501相对于偏心轴5052的曲柄半径5052的位置做相似运动。相对于该轴垂直放置的板子5050或包围该植入体的框架将连接元件5051,5053,偏心轴5052,以及间接通过支座5051,5053组合的下板502固定在恒定位置。为了用视图清楚表现内部的结构在其他实施例中没有表示出框架(5050)。
在根据图5的变体中,缺点在于,组合的上板501在偏心轴5052上有倾斜趋势。因此可以以使用两个偏心轴5052的方式对该实施例5a进行改进(图6,5b),其目的是防止组合板的倾斜,并允许分别调整高度h1和h2。通过构造影响相对运动的切口5012和/或构造偏心轴5052上偏心部分的位置和长度,可以分别只调整相应的组合板的一部分。相对应的,例如,当偏心轴5052,5053旋转时,可以改变两个区的调整高度,这意味着仅仅调节后部53或仅仅调节前部54。
图7表示了具有四套不同的组合板501,502,503和504的一个变体,不同点在于它们的连接开口(例如5011,5012,5013和5014)。可通过交替变化连接开口的方位或其尺寸获得这种差异。而且,所显示的这些偏心轴分成两部分,每个部分都具有不同的曲柄半径。
高度调整的实施例还可以被构造成板子501和502的切口是等同的,而偏心轴5052具有多个独立的偏心,它们具有相同或不同的曲柄半径(图8,5c)。这样,可沿着偏心轴5052实现不同的相对运动。当仅有一个偏心轴时,为了减少上文提到的倾斜趋势,还可以使用大致是矩形的连接元件5051和5053。
在另一个实施例中(图9,5d),调整机构包括板子内501,502的切口5011,5013和与其配合的致动器5000,其中该致动器至少含有两个轴(5051和5053),柄,栓,螺丝,钉,滑块,楔形物或类似的连接元件,它们相互之间的距离是可调的。通过改变轴间的距离,可以改变植入体的高度和角度,其中相关的切口5011,5013的发散度结合轴距的变化决定了植入体高度的最终变化。如图9所示,中心轴5052用于支撑和/或固定致动器5000,并且其被支撑在板子的中心切口5012中。可以通过装置来调整轴间的距离,所述的装置例如与带有链轮齿的齿杆,弹簧锁或夹子调整装置或螺纹主轴(5054或5055)咬合。另一个调整选择是通过使用电的或压电操作的调整装置或通过基于记忆形状的材料的致动器5000内的长度的改变来实现。
如果接触表面没有与椎骨的端板平行排列(或没有分别限定)而是调整了一个角度,这可以通过使两个轴同时同方向移位来实现;例如,通过转轴支撑来实现,该转轴支撑的相对于组合板和/或封闭框的位置可以通过螺纹来调节。如图所示,轴5051,5052和5053相对于彼此的移位动作是通过使用转轴或其他的线性驱动机构实现的。
实施例5e描述了椎间盘植入体的另一个变体(图10)。变体5e是由多个板子组成的,它们相对于上板501和下板502交替排列。该实施例的一个特征是组合了拥有至少一个横向开口571的容器5050。通过这个开口571,穿透骨锚572被导入椎体,并与骨1连接。因此该实施例5e提供了更好的初期稳定性。而且,实施例5e具有三个偏心轴5051,5052以及5053,它们被支撑在前部5050和后部5054的位置并通过卡扣环5012轴向定位。根据凸轮的形状和位置,可以调整各种生物力学的重要性能。例如,在此显示的实施例5e通过所选择的切口5011,5012,5013而提供了可以在横向以及高度上扩展的植入体。
变体6描述了优选用于后外侧通路的实施例(图11)。图示的该植入体具有一个(或多个)切口64用于放置骨移植材料。为了更好的分开椎间盘室,板子601、602的前引导槽6012,6022的植入体的前安装角可从中间移到侧面。其中前引导槽6012,6022的角度642针对每一块板子(例如从侧面6011到中间6019)是变化的,以使高度的增长具有横向形状并因此优化地调整为端板的几何形状。
关于本发明2的植入体的植入,现在以举例(图12和图13)的方式展示了两种植入装置7a和7b。一方面,装置7a被设计成具有远端72的杆71。植入体的板子被远端72包住产生刚性连接,以使具有钩状部分的元件的板子在插入期间由所述装置保护以避免意外弯曲,并且所述装置的壁的厚度没有增加植入体的高度。在实施例7b中,所示的装置用于以一种不同定向方式将另一个植入体插入;所述的装置执行如同实施例7a的相同的保护功能,然而整体高度在植入期间有最小化的增长。使用杆71,植入体可以与所述装置(例如通过连续的齿杆)连接,特别是可以使得植入体牢固固定并如果有必要也可被移出。
另一个实施例8a描述了本发明重新定位机构的实施方法(图14)。脊椎植入体8a由至少一套组合板801,802,803和804,固定装置806,各种连接元件8051,8052,8053和8054以及至少一个偏心轴8055组成。连接元件8051,8052,8053和8054在支座端8065连接到固定装置806。而且,固定装置806拥有合适的元件8062用于锚定在端板上。各个组件的放置方式是一旦偏心轴8055旋转,组合板内就发生升起和平移组合的运动(图15)。例如,偏心轴8055的旋转(891-895)可以在板子801和802之间产生蠕动式的运动,导致在植入体8a的齿状的表面上出现总体上的线性运动或平移890。使用所述的机械平移重新对错位的椎骨定位,因此矫正AP位置。图16证实了这样的重新定位的过程。为此,植入体8a被插入椎间隙81。具有固定装置的末端固定在位于椎骨102的前面边缘的位置82;在本图中以举例的方式显示了骨螺钉9。随后,使用装置7将旋转运动传递到偏心轴8055上。由于偏心轴8055旋转,脊椎植入体在下面的椎骨的端板上在AP方向执行了平移运动890,由此椎骨被定位和/或椎骨的位置被矫正84。
图17中显示了本发明的重新定位的机构8b的改进的实施方案。脊椎植入体8b包括:至少一套组合板801,802,803和804,固定装置806,不同的连接元件8051,8052和至少一个转轴8055。连接元件8051,8052连接到转轴8055的支座端8057和8058。通过轴螺母8056将转轴8055与框架806连接。另外,板子在骨方向上的特征形状有利于将端板101锚定在重新定位的方向8019和8029上。在轴螺母8056的帮助下使转轴移位;所以组合板801和803的一部分被传输(85)。随着将骨孔和槽(8011和8021)用于支撑轴8051和8052的过程,可以首先改变植入体的高度(87)(图18)。在转轴运行后,发生平移(88)以提供平移并因此重置(89)。
