Description
发明领域
本发明涉及一种人造的生物兼容的椎骨装置,更具体地说,涉及一种用于治疗背痛的椎骨间脊椎植入物。
背景技术
许多医学状态如压迫脊髓神经根部、椎间盘退化疾病、肿瘤和创伤可以产生严重的背痛。椎骨间融合是一种减轻背痛的外科方法。在椎骨间融合中,通过移去受感染的椎间盘和插入一个植入物而将两个相邻的椎骨体融合在一起,该植入物将允许骨头在两个椎骨体之间生长而桥接由于移去椎间盘而留下的间隙。另一种缓解背痛的外科方法是利用椎骨体摘除和脊椎植入物移入技术(corpectony),在该技术中,移去得病的或受损的椎骨体及邻接的椎间盘而用一脊椎植入物代替,该植入物将允许骨头在最近的两个椎骨体之间生长,从而桥接由于移去脊椎组织而留下的空隙。
许多不同的植入物材料和植入物设计已用于不同程度地成功的椎骨体间融合和椎骨体替换。当前使用的植入物材料包括金属、射线可透过材料包括塑料、弹性材料和聚合物材料、陶瓷以及同种移植物。当前的植入物设计从有螺纹的圆筒形植入物到带有齿状凸出部的矩形架。
例如,Zdeblick等人的美国专利No.5,782,919公开了一种体椎骨间融合装置,该装置有一个限定一空心内部的锥形椎骨体,用于接受一个骨移植物或骨替代材料。其次,该装置的椎骨体带有用于咬住相邻椎骨的外螺纹,并有一系列用于促进骨长入的形成血管的孔。该设计的一种变化方案示于Ray等人的美国专利No.4,961,740中。该专利例示一种空心的圆筒形融合架,在架的外表面上设有螺纹,在螺纹之间带有多个引向空心中央的孔。
Henty等人的美国专利No.5,766,252讨论一种矩形的椎骨体间脊椎间隔物,该间隔物具有隔开一个对应于所需间隔的距离的垂直对置的上下负荷支承表面。该刚性部件有一个楔形构形,在该部件的前端处有一尖端。
虽然上述每种假体讨论某些有关椎间盘替换或椎骨体和椎间盘的替换,但它们还存在其它问题。因此,需要这样一种椎骨间植入物,其设计考虑了填充了椎骨间假体的椎骨间空间的解剖生理和几何形状以及相邻椎骨体的端盘的解剖生理和几何形状。同时也需要这样一种椎间盘植入物,该植入物与其间插入了植入物的相邻椎骨体的椎骨组织良好地形成一体。
发明概要
本发明涉及一种椎骨间植入物,用于当需要椎骨体的外科融合时。该植入物可以用于替换一个得病的或受损的椎间盘或可以用于替换一个得病的或受损的部分或完全的椎骨体,或可以用于替换一个得病的或受损的椎骨体和相邻的椎间盘。
在一个实施例中,该植入物包括一个用一种生物兼容金属、射线可透过材料、同种移植物或可再吸收的材料制成的椎骨体,该椎骨体的尺寸和形状基本上符合该椎骨的端盘,该植入物有一楔形轮廓并有一个中心孔,用于接受一种有助于骨生长的材料,以促进新骨头的生成。这些顶面和底面可以是平坦的无角表面、楔形的或弯曲的表面。最好是,这些顶面和底面仿制椎骨端盘的起伏构形。这些顶面和底面每个可以有从该植入物的一个外周边延伸到该中心孔的有多个齿的区域和从该植入物的该外周边延伸到该中心孔的基本上光滑的区域,前一种有齿的区域用于啮合相邻椎骨的端盘,而后一种基本光滑的区域用于接受一种外科器械。这些基本光滑的区域可以沿前后方向、横向而延伸或可以沿两个方向而行走。此外,该基本上光滑的区域可以沿一个前-横侧方向行走。
该植入物在其至少一侧上有至少一个通道,用于接受一种外科工具或器械。该通道也可以沿至少一个前后方向、一个横向或沿两个方向而延伸。
在另一实施例中,并没有器械接受通道,该植入物可以在其前侧、前-横侧或横侧上有一螺孔,用于接受一插入工具的有螺纹的臂。
在又一实施例中,该植入物可以有一可叠合性的特点,其中该植入物可以组合而包括一上端帽和一下端帽或一上端帽、一下端帽和至少一个椎骨体部分。

优选实施例详述
图1表示按照本发明的一种椎骨间间隔物或植入物10的第一实施例。植入物10大体上为肾状,包括前侧12、后侧14、第一横侧16和第二横侧18。前侧12和横侧16、18全都基本上为拱形,最好为凸形,而后侧14基本上为拱形,最好为凹形。
植入物10还包括中心孔26,该孔可填充骨生长诱导物质,以允许骨长入和进一步帮助相邻的椎骨和该植入物的融合。中心孔26大体上为肾状,基本上符合植入物10的肾状。中心孔26的拱形的最好为凸形的各侧的曲率半径23可以为约6.5mm~约8.5mm,最好为约7.5mm,而该最好凸形的侧面和最好凹形的侧面之间的区域的曲率半径25为约3.0m~约3.4mm,最好为约3.2mm。
此外,植入物10的上表面15和下表面30上有具有齿20、刺突或类似的咬住构造的区段或区域,以便于植入物10与相邻椎骨的端盘的啮合。这些齿可以是金字塔状、锯齿状或其它类似形状。其脊部也可以用于便于咬住相邻的椎骨。植入物10也可以有基本上光滑而没有任何凸出部的区段或区域22或24或两者。区段22、24用来帮助外科医生植入该间隔物,如下面将讨论的。
如上所述,植入物10大体上有一肾的形状。该形状设计成其尺寸和形状与其中植入植入物10的椎骨端盘的总周边和形状符合一致,从而提供最大的支承而同时避免椎骨体的椎骨间孔。椎骨间孔或脊锥腔是椎骨体的罩住脊髓和神经根的部分。通常,椎骨间孔的一部分伸入该椎骨的体部分或端盘部分。事实上,椎骨间孔的这一部分将该锥骨的体部分的周边从基本上的椭圆形变为基本上的肾状。因此,植入物10的形状为肾状而竭力模仿相邻椎骨的体部分的大体形状和周边。
植入物10最好也具有大体上楔状的侧视轮廓,该轮廓设计成在已除去受感染的盘或受感染的椎骨体及毗邻的盘之后恢复该脊椎的自然弯曲或脊柱前凸。如图2和图4中所示,该楔状是由于从前侧12的高度逐渐增高而向后侧14的高度降低而产生的。该植入物具有从横侧16到横侧18基本上恒定的高度。在另一优选实施例中,该植入物从横侧16到横侧18可以具有从高度逐渐增高到高度逐渐降低。上表面15和下表面30的基本上凸形的弯曲改变植入物10的沿前后方向的高度。在另一优选实施例中,上表面15和下表面30的基本上凸形的弯曲改变植入物10的沿横向的高度。植入物10最好在其中心和前侧12之间的大体中间处有最大高度。在一个示范实施例中,上表面15和下表面30也可以是平坦的无角表面或平坦的有角平面。或者是,上表面15和下表面30可以基本上为弧面,最好其形状模仿椎骨端盘的起伏构形。
为了便于插入植入物10,后侧14和前侧12向上下表面15、30的过渡具有圆角边缘40。圆角边缘40可以使植入物10在两个端盘之间滑动而同时尽量减小端盘的必要的叉开。在一优选实施例中,圆角边缘40具有约0.75mm~1.75mm的曲率半径,最好为约1.25mm。在另一优选实施例中,圆角边缘40可以围绕植入物10的周边而延伸。圆角边缘40也可以用作通过消除位于植入物10的边缘上或邻近于该边缘的任何半齿或部分齿而清洁这些边缘的方法。
如图2和图3中所示,通道32从前侧32通过中心孔26到后侧14地穿过植入物10而延伸。通道32的尺寸做成可以接受一外科器械如用于植入植入物10的插入物。此外,沿通道32的侧面,靠近前侧12,设置了止动槽34,它们进一步帮助将植入器械联接在植入物10上。与通道32和止动槽34一起使用植入器械,可将植入物10插入一个前通路中,其中后侧14是被引入椎骨间空间内的第一侧面。
一个接受第二器械的通道38可以从第一横侧16延伸到第二横侧18。通道38的尺寸也做成可以接受一外科器械如用于植入植入物10的插入物并有止动槽36和37,以进一步帮助将植入器械联接在植入物10上。与通道38和止动槽36一起使用植入器械,可以将植入物10插入一横向通路,在该处横侧16是被引入该椎骨间空间内的第一侧面。或者是,与通道38和止动槽37一起使用植入器械,可以将植入物10插入一横向通路,在该处横侧18是被引入该椎骨间空间内的第一侧面。
虽然脊椎间隔物插入器械在该技术中是已知的,但一个与植入物10一起使用的插入物可以被修改而任选地包括可脱开的啮合部件,其形状和尺寸可以与止动槽34、36、37啮合而在插入和安装手术期间进一步帮助保持该插入物。
如可从图2和图3中看到的,图示的通道32延伸植入物10的两个横侧16、18的整个长度。但是,在一个示范实施例中,通道32可以仅延伸两个横侧16、18的长度的一部分,或者可以仅延伸两个横侧16、18之一的长度。同样,通道38可以仅延伸两侧12、14的长度的一部分,或可以沿两侧12、14之一延伸。
为了进一步帮助插入和植入该植入物10,植入物10有位于植入物10的上表面15和下表面30上的区域22和24,这些区域基本上是光滑的,其尺寸可以接受一个器械,如在该技术中熟知的叉开器。在该特定的实施例中,区域22沿前后方向延伸而便于前面的植入物插入,而区域24沿横向或侧向方向延伸而便于植入物的横向插入。虽然在图1中区域22图示为从前侧12的周边边缘到后侧14的周边边缘而沿植入物10的整个纵向长度延伸,但区域22也可以沿植入物10的纵向长度仅部分地延伸。上述内容也适用于区域24。区域24图示为沿植入物10的整个横向长度延伸,但是,区域24也可以仅沿植入物10的横向长度的一部分延伸。其次,在一示范实施例中,可以只有如图4A中所示的区域22或只有如图4B中所示的区域24存在于植入物10的上下表面15、30上。
植入物10可以用纯钛或其合金制造,最好氧极化处理,以使其更加惰性而增加其生物兼容性。植入物10也可以用一种射线可透过的材料如聚醚醚酮或聚醚酮酮制造,并可包括一射线透不过的标记如钛合金销钉。该射线透不过的标记可沿植入物的任何侧如前侧12、后侧14或横侧16、18安置。通过利用一种射线可透过材料,可以使用X射线或类似装置来跟踪融合的状态和进展,而该射线透不过的标记将指示该植入物相对于相邻的椎骨体的位置。植入物10还可用其它生物兼容材料如同种移植物和/或其它可再吸收的材料制造。
植入物10的尺寸可根据该植入物将插入的脊锥中的部位而变化。例如,腰区脊椎中的椎骨体大于胸区脊椎中的椎骨体。因此,一个预定用于胸区的植入物将小于腰区的植入物。同样,较低的腰椎间盘替代物将大于较上部的。一个普通专业人员可以配用该植入物的基本尺寸,使其占据原先由需要替换的特定椎间盘占领的空间。植入物10的尺寸通常做成用于前面的、侧面的或前面一侧面的通路,其中不需要像在前面通路中那样地围绕脊髓或脊硬脑膜囊插入该植入物。植入物10的一个示范实施例可以有一个15mm~40mm的宽度(从前侧12延伸到后侧14),但优选的为约22~26mm,最优选的为约24mm,还有一个20mm~50mm的长度(从横侧16延伸到横侧18),但优选的为约28~32mm,最优选的为约30mm。此外,在一个示范实施例中,当用作椎骨间间隔物时,作为上表面15和下表面30之间的距离度量的植入物10的高度可以为约5mm~约25mm。当使用植入物10作为椎骨体摘除和脊椎植入物移入技术(corpectomy)装置时,植入物10的高度可以为约17mm~约100mm。其次,在一个示范实施例中,该凹形侧的曲率半径19(示于图1)和凸形侧的曲率半径17(示于图1)可以为约8mm~约30mm,但最好为约13mm。连接凹形侧14和凸形侧16、18的过渡区13的曲率半径21可以为约4mm~约8mm,但最好为约6mm。同时,在一个示范实施例中,植入物10的从前侧12到后侧14的上下表面的曲率半径可以为约40mm~约100mm,但最好为约50mm。上下表面15、30在横侧16、18之前最好为平坦的。
图5表示植入物100的第二实施例的顶视图。通常,植入物100的大部分结构类似于植入物10的结构或可与其比拟。因此,植入物100的等效结构的标号与植入物10相同,而相似的部件和特点的讨论相信并不需要。在该特定的实施例中,区域110位于植入物100的上表面15和下表面30上。区域110同时沿纵向和横向的对角线延伸穿过植入物110,以便于沿前面一侧面插入植入物。虽然在图5中区域110图示为沿植入物100的整个长度延伸,但区域110可以仅仅部分地沿植入物100的长度而延伸。
与上述植入物10相似,植入物100有两组器械接受通道,以便当插入植入物100时增加外科手述的灵活性,并通过产生更多的外科插入替代物而便于该插入过程。在前面一侧面插入的情况下,无论是具有止动槽36和37的通道38还是具有止动槽34的通道32,都可以使用。
图9表示植入物200的第三实施例的顶视图。通常,植入物200的下部分结构类似于植入物10的结构或可与其比拟。因此,植入物200的等效结构的标号与植入物10相同,而相似的部件和特点的讨论相信并不需要。在该特定的实施例中,植入物200不是具有接受器件的通道,而是有螺孔210、212。螺孔210、212的尺寸可接受一个植入器械如有螺纹的插入物。
如可在图10和图11中看到的,螺孔210位于横侧18上。该位置允许以横向方式插入植入物200。虽然螺孔210位于横侧18上,但螺孔也可以位于横侧16上。该位置也允许沿横向插入植入物200。图11和图12表示位于植入物200的前侧12上的螺孔212上。该位置允许沿前面方向插入植入物200,而后侧14是引入椎骨间空间内的第一侧。
图13表示植入物300的第四实施例的顶视图。通常,植入物300的大部分结构类似于植入物10的结构或可与其比拟。因此,植入物300的等效结构的标号与植入物100相同,而相似的部件和特点的讨论相信并不需要。在该特定的实施例中,植入物300不是具有接受器件的通道,而是有螺孔310。螺孔310的尺寸可接受一个植入器械如带螺纹的插入物。
如可在图15和图16中看到的,螺孔310位于植入物300的前-横侧上(在前侧12和横侧16之间)。该位置允许以前-横侧方式插入植入物300。虽然螺孔310位于一个前-横侧上(在前侧12和横侧16之间),但它也可位于另一个前-横侧上(在前侧12和横侧18之间),也允许一种前-横侧植入。
在一第五实施例中,植入物400类似于前面公开的实施例,但有一可叠合性的特点。如将在下面进一步说明的,植入物400包括一个上端帽和一个下端帽,它们可以叠合而形成该间隔物或植入物。如图16A中所示,植入物400也可以包括至少一个主体部分,它可以被叠合在该上端帽和下端帽之间而形成该间隔物或植入物。图17表示植入物400的上端帽402的顶视图。上端帽402有一大体上肾的形状,它包括前侧403、后侧404、第一横侧406和第二横侧408。前侧403和横侧406、408都基本上为拱形,最好为凸形,而后侧404基本上为拱形,最好为凹形。
如图17~20中所示,上端帽402也包括两个长孔410,它们能填充骨生长诱导物质,以允许骨长入和进一步帮助相邻椎骨的融合。上端帽402还包括一个中心孔411,用于接受一紧固部件如螺钉。此外,上端帽402的上表面405上具有有齿412或类似咬住机构的区段或区域,以便于使植入物400与相邻椎骨的端盘啮合,并具有基本上光滑而没有任何凸出部的区段或区域414、416。虽然在图17中区段414、416图示为沿上端帽402的整个长度从一周边到另一周边而延伸,但区段414、416也可以仅沿上端帽402的长度的一部分而延伸。区段414、416可以帮助外科医生沿前侧或沿横侧植入该植入物,如上面对于区段22、24的讨论。如可在图18和图21中所见,上端帽402有一大体上矩形的凸出部418,其形状和尺寸能与植入物主体的一个凹部或与下端帽进行接口和啮合。虽然凸出部418已图示和描述为大体上矩形,但可以理解,凸出部418可以是任何所要形状。一个下表面407围绕该凸出部418,但可以理解,下表面407也可以仅仅部分地围绕凸出部418。
上端帽402可以有一大体上楔形的侧面轮廓,该轮廓设计成在移去受感染的盘或受感染的椎骨体及相邻盘之后能恢复脊椎的自然弯曲或脊柱前凸。如图19中所示,该楔形是通过高度从前侧403向中间逐渐增大和高度从中间向后侧404逐渐减小而实现的。上表面405的基本上凸形的弧面沿植入物400的宽度改变其高度。在一示范实施例中,上表面405也可以是一个平坦的无角表面、一个平坦的有角表面或一个基本上弯曲的表面,最好是其形状仿制相邻椎骨端盘的起伏构形。上表面405的曲率半径可以与上述一件式植入物的相同。

图57表示椎骨体部分550的顶视图。通常,椎骨体部分550的一部分结构相似于端帽502、520和530的结构或可与其比拟。因此,椎骨体部分550的等效结构的标号与端帽502、520和530的相同,而相似的部件和特点的讨论相信不需讨论。如可在图57~62中看到的,椎骨体部分550大体上有一肾的形状。椎骨体部分550具有位于上表面555和下表面557上的限定一空腔564的台肩562和大体上矩形的凸出部556。虽然台肩562图示为完全环绕和围绕空腔564,但台肩562也可以部分地围绕空腔564。同样,上表面555和下表面557图示为完全围绕凸出部556,但可以理解,上表面555和下表面557也可以部分地围绕凸出部556。台肩562和空腔564的构形和尺寸做成可以与端帽502、520、530的矩形凸出部518或另一椎骨体部分550的矩形凸出部556中的任一个进行接口和啮合。椎骨体部分550的凸出部556的构形和尺寸做成可与端帽502、520、530的空腔513或另一椎骨体部分550的空腔564中的任一个进行接口和啮合。又一次,虽然这些凸出部已描述为矩形,但可以考虑任何几何形状。
如上所述,植入物500是一种包括两个端帽502、520、530和(如果需要)至少一个椎骨体部分550的可叠合的植入物。植入物500的可组合性允许植入物500有一可变的高度,由此允许外科医生制造一个其尺寸能合适地配合该外科手术空间的植入物。在使用中,一旦确定了外科手术所需要的植入物高度,就可以用这两个端帽和(如果需要)一个或多个椎骨体部分来制造所要的植入物。如果需要一个较小的植入物,植入物500可以包括两个端帽502、520、530。如果需要一个较大的植入物,植入物550可以包括端帽502、520、530和至少一个椎骨体部分550。椎骨体部分550可以是同一尺寸或各种不同尺寸。端帽502、520、530和椎骨体部分550的构形和尺寸做成可以通过压配合或类似配合而彼此啮合。为了进一步固定这些端帽或这些端帽和椎骨体部分一起,可以将一固定螺钉旋入中心孔511内。也可使用额外的螺钉和孔。
