技术领域
在此描述和图示一种新颖的骨骼再造植入物的几个实施例。这种植入物通常包括一个活动部分、两个板部分、以及一个运动限制部分。
发明内容
这种植入物的各主要实施例用于脊柱再造,然而,这种装置也可应用于非脊柱的外科整形,只要是需要将两个骨头或骨头的几个部分结合起来,皆可应用之。在应用于脊柱中,这种装置的活动部分可被调整而在矢状面中呈现不同的角度,来使脊柱前凸或脊柱后凸恢复正常,和/或在冠状面中呈现不同的角度,来矫正任何脊柱侧凸变形。这种装置还可被沿着纵向轴线或横向平面来调整。较佳的是,活动部分允许板部分上的骨表面接合部分在所有平面内在生理上的脊柱曲度之内以任何角度取向。或者,可用运动限制部分来限制活动部分,从而只允许选定的运动,例如围绕单个平面或围绕单个轴线以递增的变化量运动。在一较佳的实施例中,可成形运动限制部分来阻止或锁定除了由活动部分所允许的之外的大致所有运动。当需要诸骨部分之间的结合时,这种完全的锁定模式尤其有用。
在活动部分发生的相对运动可使植入物的第一骨表面接合部分和第二骨表面接合部分之间有大量可能的角度和平移取向。这种运动使这种装置具有特点而成为一种角度可变的或多位置的再造装置。在各较佳的实施例中,可原位地调整该角度或位置变化,从而匹配于其内设置了植入物的骨部分的独特的生理取向。
例如,如果这种装置是用在两个椎骨之间的椎间空隙里,可将上板部分和下板部分先插入椎间空隙,且以活动部分来使骨表面接合部分取向,从而与患者脊柱的椎骨部分的独特曲度相匹配。然后,外科医生可选择一个运动限制器来将骨表面接合部分锁定于这个取向。例如,如果这种装置是用在患者脊柱的第四和第五腰椎骨之间,脊柱在各椎骨部分之间有5度的脊柱前凸和0度的脊柱侧凸,则外科医生可选择具有类似这些角度特征的运动限制楔,来放置和锁定于装置的各骨板部分之间。然后,这个运动限制楔用来把植入物锁在一个与生理上的脊柱曲度相匹配的取向。为此,可将运动限制器成形为可互换的或可拆除的。
也有外科医生可能不愿意使用运动限制器来驱使植入物与两个骨部分之间的生理空隙相匹配的情况。或者,运动限制器可用来在两个骨部分之间驱使预定的治疗角度或取向。例如,为了减轻有问题的脊柱侧凸,外科医生可选择一种迫使脊柱侧凸减轻的运动限制楔。无论如何,都可用运动限制部分将植入物的骨表面接合部分调整至多个取向。
植入物的板部分典型地是用作一个供植入物的与骨部分以及与植入物的活动部分和/或运动限制部分相接触的结构坐落的平台。板部分具有用于与骨部分相接触的骨表面接合部分。板部分还可具有适于诸如骨组织之类的组织向内生长的多孔表面。每个骨表面接合部分可包括突入被结合的骨部分的表面的长钉、销钉、龙骨、或其它突起。多孔表面和突起有助于使板部分坐落入暴露的骨部分,以防止其间的运动,并且用于将板部分固定于骨。为了最好地配合,板部分的骨表面接合部分可构形或成形为与将要配对的骨部分的形状互补。因此,骨表面接合部分可以是平的,可以是凹入地或凸出地曲面的,或者可以呈现能够与骨部分互补的任何其它形状。
接头板表面位于板部分的不直接与骨部分相接触的那一部分上。该接头板表面成形为与植入物的活动部分互补或成为其一个组成部分。例如,接头板表面可具有凹入的轮廓,从而与凸出的接头间隔件或与成形在独立的板部分上的相反的凸出表面一起形成球窝接头。
每个装置的板部分可包括适于诸如接骨螺钉之类的紧固件穿过的通孔或其它结构,或者可包括与之成一体的紧固件,借以将装置固定于骨部分的周围骨体。
植入物的活动部分可形成几种不同的接头。例如,接头可以是一种诸如球窝接头的关节接头、一种铰链、或其它形式的配对的凹凸接头、一种诸如位于两个板部分之间的弹性体的弹性体接头、一种枢转接头、一种平面接头、或一种采用充填液体或气体的囊的接头、或它们的任意组合。在活动部分发生的运动可使植入物的两个骨表面结合部分之间有大量可能的角度和平移取向。
活动接头的形式可以具有包括成形在每个板部分上的凹入的、凸出的或凹凸组合的接头表面部分的轮廓或构造。植入物的一个间隔件部分具有大致匹配于板接头表面部分的曲度的凸出的或凹入的表面部分,该凸出的或凹入的表面部分是成形在间隔件部分的表面上。随着将间隔件部分放置于两个板之间,就形成两个关节接头。配对的凹入的和凸出的接头表面部分的半径可以相匹配或不匹配。如果半径不匹配,则凹入表面的半径通常大于凸出表面的半径,但是这两个半径中的任一个可以大于其中的另一个。另一种接头接触面轮廓包括在两个板部分之一上的凹入内接头板表面部分和在另一个板部分上的凸出内接头板表面部分。将这些接头接触面轮廓结合在一起可形成两个板之间的关节接头。
运动限制部分可用于把植入物的骨表面接合部分锁在一个预定的取向,或至少将它们的相对运动限制在一个预定的运动范围内。根据运动限制器的类型,可将其在植入装置的其它部分之前、过程中或之后插进去或以其它方式放置。可将运动限制器整体地成形为植入物的一部分,诸如在板部分或间隔件部分内。然而,运动限制器最好是单独的零件,从而外科医生可在把植入物的其它部分植入到位之后方便地应用它,并且可再次评价两个骨部分之间的取向。
运动限制器可以呈一个位置限制件或锁的形式。成形限制件部分是为了阻止植入物活动部分的运动。然后,由限制件的形状和/或位置来确定植入物的骨表面接合部分的最终位置取向。限制件的轮廓或构造可以是各种各样的,某些例子包括诸如楔子、斜面环之类的成形插件、充填有诸如可固化聚合物之类的不可压缩材料的囊状物、能够弹入预定的凹处而阻止诸表面之间的移动的弹簧销或可以其它方式放置的销子、能够堵塞需要产生运动的活动部分内的空间的柱子或凸轮、或可将板部分支承在一个固定不动的或运动受限制的位置的板。可将这些限制件以几种不同的方式固定、连接或配对于植入物。一些例子包括楔入、齿啮合于、螺纹连接于、咬合于、凸轮接合于、或锁入植入物。限制件还可纳入植入物内,从而不需要单独的连接。
运动限制器或限定器的另一实施例采用设置在两个板部分之间的至少一个支柱。支柱的长度可以是固定不变的或可调整的,并且可在选定了所需长度之后锁定。可将支柱连接于板部分来控制板部分的角度变化,并且可通过各种方法来连接于或固定于板部分。例如,可用螺纹或球窝连接将(各)支柱连接于板部分。如果用螺纹,则一种可变角度的螺钉头是较佳的。
运动限制器还可包括粘合剂或其它粘结剂,诸如磷酸钙骨接合剂,用以将活动部分锁定于预定位置。可将这样的料剂例如用在两个接头表面部分之间,借以将它们结合成彼此固定的关系。类似地,与几种其它的可生物相容的材料一样,运动限制部分可用骨头或骨头替代物或能够促进骨生长或提供骨生长路径的其它物质来制成。一个例子是重组体骨形态构成蛋白(BMP)。通过用适当的BMP成形运动限制器,这种材料可促进结合并起运动限制装置的作用。或者,运动限制器可用胶原基基质制成。
植入物的运动限制部分可由诸如可吸收骨替代物或聚合物之类的生物可吸收材料制成。表明这类材料的好处的一个例子是在把这种再造装置用于延缓运动保持时。例如,在脊柱再造手术之后,在康复的早期,外科手术位置有一个固定期,这往往是较佳的。因此,有这样一种椎间运动保持装置是有利的,该装置最初锁定或限制运动,但是随着康复过程的进行将允许逐渐增加运动。通过采用这种生物可吸收的运动限制器,可将这种再造装置植入于预定的固定或锁定的取向。然而,随着运动限制器被吸收,再造装置将恢复预定的运动量,并且充当椎骨部分之间的运动保持装置。这种装置可类似地用于人体的其它关节。
作为安全特征,植入物的活动部分可设计成模仿正常功能的椎间盘。因此,运动限制器的失效或缺失不会导致植入物完全失效。在这种情况下,以及在工作的后备模式中,植入物可长期地或短期地适当地充当运动保持装置,十分类似于正常的人体椎间盘,直到发生穿过植入物的结合。
如果植入物用于多段椎骨本体的更换,每段可包括一个活动部分,从而可在每一段上调整一个椎骨本体相对于另一个的运动或取向。
植入物的各部分可以有通孔,或具有通路,以允许骨生长进入植入物,以及从一个骨部分穿过植入物而向另一个骨部分生长。当存在通路时,这些通路有助于达到两个骨部分之间的最佳结合。
植入物可用各种生物可相容的材料制成。这类材料包括PEEK以及其它生物可相容的聚合物、骨头或骨头替代物、BMP、不锈钢合金、钴铬合金、钛和钛合金、或这些材料的组合,列出的这些仅仅是一些例子,而非穷尽了。
具体实施方式
图1中的实施例表示出植入物100的一个活动部分150。活动部分150典型地是被放置在骨表面接合部分110、120之间,并且有利于在每个骨表面接合部分110、120之间的至少一个平面内或围绕至少一个轴线运动。由植入物100的活动部分150提供的运动可使骨表面接合部分110、120向骨部分160谐和地取向,从而使骨表面接合部分110、120与骨部分160之间的表面接触最大化。这种表面和表面接触的最大化有利于骨更好地向多孔表面140内生长,进而达到骨表面接合部分110、120与骨部分160之间的更牢固的固定。多孔表面140和骨表面接合部分110、120都可被成形在上板部分170和下板部分180上。
在用植入物形成一个关节接头的情况中,这种接头可具有几种不同的轮廓或构造。本发明的脊柱结合植入物的一个实施例100(参见图1和2)包括第一骨表面接合部分110和第二骨表面接合部分120,用于固定于不同的骨部分。这些骨表面接合部分110、120形成于上板部分170和下板部分180上。接头板表面190也形成于上板部分170和下板部分180上,并且起补充作用的接头间隔件表面200形成于接头间隔件210上。在此实施例中,接头运动可在每个接头板表面190和接头间隔件表面200之间双节点地产生。
此实施例中的运动限制部分220包括一个上限制器240和一个下限制器250。尽管此实施例中的限制器240、250是环状的,但是应该注意到,它们可以具有许多种轮廓,只要它们最终能够将板部分170、180支持、固定或锁定于所需的取向。如图所示,这些限制器240、250可包括一开口壁270,从而在这种情况下,允许把限制件240、250弹性地压缩,而后把限制器240、250的保持边缘280配对进接头间隔件210的接纳槽260中。开口壁270不是必需的,因为可把限制器240、250和保持边缘280的尺寸确定为紧配在接纳槽260中。限制器240、250可利用许多其它类型的连接,诸如螺纹连接、或推转卡口式的连接。同样在此实施例中,应注意到,限制器240、250可包括锁定突舌230和锁定凹口290,或其它类型的凸起或特征结构,用以防止限制器240、250相对于该装置的其它组件作转动或其它运动。
运动限制器220可被以一个优选的角度α倾斜(图2)。一套这种结合装置可包括多个可互换的运动限制器240、250,其中每个以不同的角度α倾斜。这种倾斜可在不只一个平面内发生。各个以不同的预定角度倾斜的运动限制器220的恰当组合可使植入物最好地匹配两个骨部分160之间的角度β。根据不同患者的不同需要,一套装置还可包括多种尺寸和厚度的其它部件,并且可包括用于插入植入物的仪器。可将脊椎结合植入物100的尺寸确定为能够附着于骨部分160的全部或一部分。在这种装置用于脊柱手术的情况下,可将这种装置的尺寸确定为占据一个椎骨间空隙的全部或一部分。
在一种替换的关节接头轮廓中,植入物400的活动部分410可以没有间隔件。在这样一个实施例中(图3),凹入的接头板表面430和凸出的接头板表面420是成形在植入物的上板部分450和下板部分440上。尽管表示出凹入的接头板表面430是在上板部分450上,但是可将接头板表面420、430颠倒过来,把凸出的接头板表面420成形在上板部分450上,而把凹入的接头板表面430成形在下板部分440上。应注意到,如图3A所示,所有的板部分440、450都可包括孔、槽口、或其它通路580,以便接骨螺钉(未示)或其它紧固件从其中穿过而把板部分440、450紧固于骨部分。还应注意到,通过为骨的生长打开一条穿过植入物以及在各骨部分之间的通路,孔、槽口或其它通路580可用于促进结合。尽管图3A中未表示,但是这些通路580还可延伸穿过植入物的接头板表面。这些通路可以是笔直的或弯曲的,并且可有不同的直径。
图4中描绘出一个类似于图3的实施例,其具有运动限制部分460。在此实施例中,尽管运动限制器460表示成两个固定支柱470,然而围绕活动部分410的周边在大致等腰三角形的三个顶点处定位三个固定支柱470是更佳的。各固定支柱470的长度可以是固定不变的或可调整的,这可由外科医生来选择。如果是固定的,使用者可从诸多固定长度的固定支柱的各种长度中进行选择。然后可将选择的那些支柱定位于板部分440、450的支柱通道480内。为了便于插入,固定支柱470在其两端之间可具有卡口连接,从而可把每端推靠在一起并转动例如90度,这可将固定支柱470的两端锁定在一起。最好是固定支柱470具有一个多轴的头,以便能在板部分440、450内的互补形状的座里作关节运动。多轴的头的例子是半球形的或倒角的头轮廓。另一方面,定位座490可以是倒角的、圆角的、或者具有单线接触,这种单线接触是由支柱通道480的贯通直径小于固定座490的直径来形成。在任何情况下,都应使固定支柱470和固定座490较佳地协作,以将(各)固定支柱470牢固地支持在所需的取向。可使用长度可变的固定支柱470,这就不必用各种尺寸的固定长度固定支柱470。例如,可将图4中所示的可变的固定支柱470用螺纹拧在一起,并且两个支柱470之间的相对转动可使彼此螺纹地旋动,从而缩短或增长它们的组合长度。类似地,可将支柱470做成为跨接于两个板部分440、450之间的可松脱的板的形式(未示),借以把板部分440、450保持在预定的取向。
图5和6中描绘出用在再造装置的较佳实施例中的运动限制部分500的另一形式。在此实施例中,该装置的上板部分450和下板部分440通过一个插在两个板部分440、450之间的定位楔540稳定在预定的取向上。该楔子540可以在所有平面内有多种预定的角度位置,并且与许多运动限制部分一样,可将它在板部分440、450之后或与它们同时地或随它们一起插入。如果是在板部分440、450之后插入,楔子540的斜面形状通过将两个板部分440、450推开同时在其间滑动而易于插入两个板440、450之间。一旦达到适当位置,定位楔540就通过通常的锁定作用、紧固作用或其它固定方法固定于两个板部分440、450之间。例如,在图6所示的实施例中,定位楔540上设有楔子紧固孔530。这些孔应与位于上板部分450和下板部分440上的互补的板紧固孔510对准。这些孔510可带有螺纹,并且可容纳跨接于定位楔540和板部分450、440之间的固定件。
或者,并且作为另一个例子,定位楔540可有锁定突舌550,这些锁定突舌550伸进上板部分450和/或下板部分440的前面。可用紧固件或其它连接件将锁定突舌550固定于板部分450、440。作为再一个例子,楔子540和/或板部分440、450可包括锁定脊、齿、台阶、突台560、锁定凹坑570、或一旦楔子插入两个板部分440、450之间就能互锁的其它结构。定位楔540由于其形状简单,特别适于用骨头或骨头替代物制成,并且可以是生物可吸收的。
如前所述,活动限制器可以是充填有诸如可固化聚合物之类的不可压缩或可最低程度地压缩的充填材料的囊。例如,定位楔540可以是楔状囊。这种囊典型地具有一个穿孔的或设有阀门的进入位置,借以为充入充填材料提供入口。用于充填囊的材料的较佳选择是可固化聚合物或者骨黏固粉,但是它可以是任何种类的诸如盐水之类的流体。最好是提供有各种尺寸和角度的囊。在充填时,囊鼓胀至预定的形状,借以将板部分440、450定位至预定的取向。或者,可将板部分440、450先定位于一个所需的取向,然后使囊里的材料固化而保持该取向。然而,板部分440、450的取向可以在植入的任何阶段完成。这种囊仅仅是一个例子,用以说明怎样可把运动限制器在植入物的板部分和/或运动部分的植入之前、过程中或之后插入或以其它方式设置。
作为包括一种替换的关节接头轮廓的装置的另一个例子,可将接头表面部分的一个或多个部件成形在一插件上,可将这种插件滑入、粘附、固定或以其它方式纳入板部分内,诸如图7和8中所示的装置600。装置600具有类似的上板部分630和下板部分640。这一植入物的活动部分610包括一个插入间隔件700,该插入间隔件700具有一个与接头板表面710关节连接的接头插入表面690。可将插入间隔件700插入或由板部分630、640之一保持住。插入间隔件700可包括用来将插入间隔件700固定于板部分640的结构,诸如可落入下板部分640上的凹处(未示)的一个或多个插入锁定突舌650。插入间隔件700还可附加地包括插入导轨720,而下板部分640具有互补的插入导槽730,但是这种构造可以颠倒过来。可将插入间隔件700这样地来确定尺寸和成形,尽管它被固定在下板部分640内,但是可使间隔件700能够在一个沿着其大致平的底部的平面内滑动,这样可增大两个板部分630、640之间的附加的运动自由度。
装置600的运动限制部分620包括角度柱680,这些角度柱680与插入间隔件700相配。一旦插入间隔件700滑入下板部分640,运动限制部分620就固定于插入间隔件700内。这是因为角度柱680突出穿过插入间隔件700,以及下板部分640阻止插入间隔件700的松开。
运动限制部分620可提供一个角度变化。为此,角度柱680可设有多种斜度或角度,并有不同的高度,借以提供预定的和所需的角度变化量。至少一个角度柱680较佳地包括防转动突舌670,其被接纳在配对的上板部分630上的锁定凹坑660里。可采用类似的共有结构来防止两个板体之间的转动。
对于所有的实施例,植入物的这些骨表面接合部分110、120,不管它们是否包括凸起,都可具有多孔表面140,为了使骨最佳地向植入物内生长,多孔表面140的微孔尺度应在100-1000μm范围内。例如,多孔表面140可包括诸如多孔镍钛诺合金或钽之类的多孔材料、诸如烧结的金属颗粒之类的多孔敷层、或其它类似的功能材料,只要骨能够生长入其中,以有助于植入物100固定于骨部分160。
尽管已经图示和描述了本发明的几个特定实施例,但是应该理解,熟悉本技术领域的人能够做出各种结构上的改变、变型和组合,因此认为所附的权利要求书覆盖属于本发明的精神实质和范围内的所有这些变化、变型和组合。
