Description

后路机能动态稳定系统
本申请是申请号为200780045505.8的中国专利申请的分案申请,原申请的申请日为2007年12月7日,发明创造名称为“后路机能动态稳定系统”。
本申请要求2006年12月10日提交的美国临时专利申请No.60/869,342和2007年4月27日提交的美国临时专利申请No.60/914,360的优先权,这两篇申请的全部内容并入本文作为参考。
技术领域
本发明涉及用于治疗脊柱疾病的装置和方法,具体地涉及用于控制或限制椎骨之间的相对运动的脊柱稳定系统。
背景技术
脊柱包括一系列已知为运动节段单元的关节。每个单元代表展现整个脊柱的运动学行为特征的脊柱最小组成部分。运动节段单元能够屈曲、伸展、侧向弯曲和平移。每个运动节段单元的组成部分包括两个相邻的椎骨、相应的小面关节、椎间盘和连接韧带组织,其中运动节段单元的每个组成部分都对关节的机械稳定性起作用。例如,将相邻的椎骨分开的椎间盘提供刚度,该刚度有助于约束椎骨在屈曲、伸展、轴向转动和侧向弯曲中的相对运动。
当运动节段单元的组成部分由于创伤、机械性损伤或疾病而错位或受损时,会导致剧烈疼痛和对脊柱的其它组成部分的进一步的失稳性损伤。对于具有椎间盘退变性疾病(DDD)的患者来说,受损的椎间盘提供的刚度可能不足,这在脊柱处于给定荷载下时会导致过度的椎骨相对运动,从而引发疼痛并进一步损坏椎间盘。根据所发生的结构改变的严重程度,治疗可包括融合、椎间盘切除术和/或椎板切除术。
现有的外科治疗常常涉及通过去除邻近组织而对不稳定的运动节段单元进行融合。由于多种原因,融合是一种不希望的治疗选择。例如,融合将导致永久性的刚性固定,在被融合的椎骨水平/层面(vertebral level)上产生不可逆/不可还原的运动范围损失。此外,在被融合水平上的活动度的损失使得应力被传递到其它邻近的运动节段,这会导致或加速这些节段的退变。此外,融合常常不能减轻部分或全部的疼痛。
因此,希望提供这样一种脊柱稳定系统,其是充分地机能动态的(functionally dynamic),以便控制被治疗脊柱的载荷分配特性。还希望提供一种允许进行接近正常的运动、模拟健康运动节段的生理反应并减轻疼痛的系统。
发明内容
本发明提供一种用于治疗例如由于损伤、创伤或椎间盘退变性疾病(DDD)而导致的脊柱失稳的机能动态稳定单元和系统。各单元和共同的系统构造成控制患病椎骨的屈曲、伸展和平移,从而通过恢复正常功能来稳定椎骨节段。这通过提供一种允许侧向弯曲、轴向压缩、转动、前路节段高度调节及后路节段高度调节的单元和系统来实现。该单元和系统提供足够的节段刚度,同时还控制运动的范围以使椎骨节段稳定。在使用中,该系统模拟正常脊柱的自然运动。此外,该系统构造成允许随时间进行调节、翻修手术(例如融合)和经皮植入。
根据一个示例性实施例,提供一种机能动态脊柱稳定系统。该系统可包括柔性联接器,以及可包括筒形体部,该筒形体部在其壁上包括一个或多个槽口。该系统还可包括一对用于附装到骨锚固件的夹持臂,所述臂设置在联接器的相对端。柔性联接器还可包括内部运动范围限制机构,该限制机构构造成限制柔性联接器的弯曲、压缩和拉伸运动。该系统还可包括一对骨锚固件,该骨锚固件构造成与夹持臂协作以附装到骨组织。
根据另一示例性实施例,所述系统还包括具有一对用于附装到骨锚固件的夹持臂的刚性联接器。与柔性联接器一样,所述臂可设置在联接器的相对端。但是,与柔性联接器不同,这种联接器不允许伸展或压缩。而是,该联接器通过防止此节段处的运动而促进融合。
还提供一种治疗脊柱的方法。该方法可包括将第一骨锚固件附装于椎骨和将第二骨锚固件附装于邻近的椎骨。然后可将柔性联接器附装于第一和第二骨锚固件。柔性联接器可包括筒形体部和内部运动范围限制机构,所述筒形体部在其壁中具有一个或多个槽口,所述内部运动范围限制机构构造成限制柔性联接器的弯曲、压缩和拉伸运动。
还提供一种将所述系统经皮植入的方法及用于执行此方法的器械组,所述方法对组织的损害最小且便于插入。该方法可包括在至少两个相邻的待治疗的椎骨上方产生至少一个切口,并将至少两根丝(针,wire)安置成使得每根丝单独地接触所述至少两个椎骨之一的椎弓根(pedicle)。可将螺钉固定于各个椎骨,并测量插入到两个相邻椎骨中的螺钉之间的距离。选择待附装于螺钉的柔性联接器,并基于所测得的距离调节柔性联接器的长度。
应当理解,上述一般性说明和下面的详细说明都仅为示例性和说明性的,而非对权利要求所要求保护的本发明构成限制。
结合在本说明书中并构成本说明书一部分的附图示出本发明的数个实施例,并与所作说明一起用于解释本发明的原理。
本发明的其它目的和优点将在下面的说明中部分阐述,或者可通过本发明的实施而被认识到。通过在所附权利要求中特别指出的要素及组合可实现和获得本发明的目的和优点。

现在转到附图,图1示出植入到相邻的椎骨2、4之间的机能动态稳定系统8的实施例。图2示出被植入的机能动态稳定系统的俯视图,图3示出图1-2的系统8的后视图。如图所示,系统8可包括一个或多个柔性稳定单元10,该柔性稳定单元10可被植入在脊柱的后部上以便稳定患病的椎骨2、4。
如图4A所示,每个机能动态稳定单元10可包括柔性联接器20,该柔性联接器20连接到至少一个骨锚固件50,例如椎弓根螺钉或接骨螺钉。联接器20可包括柔性体部22,该柔性体部22包括槽口24和开口26。如图4B-4C所示,柔性体部22在一端可包括夹持臂30,在相对端可包括第二夹持臂40,夹持臂30具有供骨锚固件50插入的开口32,第二夹持臂40也具有用于接纳骨锚固件50的开口33。夹持臂30、40可与体部22一体地形成或可拆分地连接到体部22。例如,如图6所示,夹持臂40的一端可具有螺纹以通过例如柔性体部22中的套管90连接到柔性体部22。
联接器20的每个夹持臂30、40可在一侧包括凹形腔穴34、44,该凹形腔穴34、44构造成支靠在半球形的球支承件60上,如图5A-5B和图6所示。球支承件60可具有通孔,从而允许其装配在骨锚固件50上。在一个实施例中,骨锚固件50可具有长形的螺纹轴52,该螺纹轴52延伸到凸缘56中,该凸缘56连接到头部54,球支承件60可置于该头部54上。凸缘56还可包括锯齿形突起57以便于锚固到骨组织上并减少锚固件50随时间的松动。骨锚固件50例如可以是椎弓根螺钉。优选地,骨锚固件50可以是中空的以使得单元10或系统8能够经皮输送。凹形腔穴34、44允许夹持臂相对于支承件60滑动或转动,从而使得夹持臂30、40能够相对于骨锚固件50运动。也可使用其它适当的结构将柔性体部22连接到骨锚固件50,同时允许二者之间的相对运动。
如图5A、图5B和图10进一步所示,一衬垫70可安置于螺钉50上并靠住凸缘56或螺母80。衬垫70可构造和成形为靠在球支承件60上。如图4A和图5A所示,组装好的机能动态稳定单元10还可包括螺母80,该螺母旋拧在螺钉50的头部54上以便将部件相互固定。
每个机能动态稳定单元10构造成允许运动范围或位移在1.5mm至3.0mm之间,这里位移可从连接至第一夹持臂30的第一椎弓根螺钉的中央到连接至第二夹持臂40的第二椎弓根螺钉的中央进行测量。此位移或运动范围可例如通过转动、伸展或平移来实现。
图6示出图4A-4C的柔性联接器的分解图。如图所示,在一些实施例中,夹持臂40中的一个能可拆除地附装于联接器20。在一个实施例中,联接器20可包括用于将第二夹持臂40和其它部件固定于联接器20的螺纹开口28。在柔性联接器20中可具有套管90,该套管90在一端具有开口92并包括围绕开口92的螺纹边缘94,该螺纹边缘94用于螺纹连接到联接器体部22。套管90可构造成容纳于联接器体部22内,并且接纳销钉100和与销钉100协作。销钉100可包括具有螺纹端部的长形体部102,体部102延伸到半球形头部区域104中并包括裙边或台肩区域106。套管90和销钉100共同形成联接器体部22内的伸展和压缩阻止装置,该阻止装置的功能是将柔性联接器20的运动范围限制在患者的中性区或活动区。
套管90的边缘92可具有螺纹以便与可拆卸的第二夹持臂40的螺纹端部46接合。联接器20的总长度可通过改变第二夹持臂40旋入套管90中的旋入量(即,改变夹持臂40进入套管90的转动圈数)来进行调节。如图所示,可拆分的第二夹持臂40的螺纹端部46可延伸为多个可压缩的指形突出部43,各个突出部43在凸缘唇47处终止。凸缘唇47用作锁定机构,防止在组装后第二夹持臂40从套管90旋开。如图8C所示,螺纹端部46还可包括用于接纳弹性体插塞110的凹槽48。弹性体插塞110可由软的、顺应性的塑性材料形成,例如硅树脂、聚乙烯或聚醚醚酮(PEEK)。当第二可拆分夹持臂40旋拧在套管90上时,插塞110与螺纹开口92相互作用,从而减少臂40和套管90之间的松弛或间隙。也可使用允许调节柔性体部的长度并同时提供对柔性体部的压缩和伸展量的控制的其它适当的结构。例如,夹持臂可通过摩擦配合、伸缩式连接或使用棘齿机构来进行附装。
如图7A和7B详细示出,在一个示例性实施例中,联接器体部22可包括筒形体部,该筒形体部由一系列盘绕单元22A构成。所述一系列盘绕单元22A在相互连接时形成梯级式的一系列槽口24,其中每个槽口24在柔性体部22的开口26处终止。在一些实施例中,所述一系列盘绕单元22A可由单独一件材料形成,使得单元22A彼此一体地相连。例如,在一个实施例中,盘绕单元22A可由单独一件管状材料刻蚀或切割而成。在其它实施例中,一个或多个盘绕单元22A可分别单独形成且彼此叠置。叠置的盘绕单元22A例如可通过焊接或通过机械连接部而相互连接。
可设想,联接器体部22可根据两个相邻槽口24之间的高度、宽度、距离或角度以及形成联接器体部22的单元22A的数量来改变刚度。此外,一个或多个单元22A可由不同的材料形成以便改变体部22的机械特性。此外,单个体部22内的单元22A、槽口24和开口26的尺寸可变。
图8A-8D示出完全组装好的柔性联接器20处于非工作状态(图8A和图8D)、完全伸展或分散状态(图8B)和完全压缩状态(图8C)的实施例。如图8A及图8D中的放大图所示,在非工作状态,销钉100和套管90未接合(即,没有阻力或阻碍)。在完全伸展或分散状态(图8B),尺寸比窄缩开口98的宽度大的销钉头部104靠接于套管90的窄缩开口98,从而防止柔性联接器体部22过度伸展。在完全压缩状态(图8C),套管90的带有窄缩开口98的端部抵靠在第一夹持臂30的内边缘上,如图所示。套管90和销钉100在联接器体部22内的协作提供了分散-压缩阻止机构以便控制或限制所能提供的运动的范围,从而不仅可防止对患病椎骨节段的损伤或损害,还可防止对机能动态稳定单元自身的损伤或损害。也可使用其它类型的协作元件,例如伸缩元件或内部活塞,以控制或限制联接器体部22的运动范围。
如上所述,机能动态稳定单元10可单独用来稳定一对椎骨节段。此外,如果需要的话,也可组合使用多于一个的单元10来形成多个水平的机能动态稳定系统12,如图9A和9B所示。多个水平的机能动态稳定系统12可包括两个或更多个相互连接的单元10。
图10示出图9A-9B所示的系统的侧视图。如图所示,系统12包括一对串联连接的柔性联接器20。联接器20设置成使得每个联接器20的第一夹持臂30围绕一个球支承件60安置,其中骨锚固件50和螺母80将此组合体固定在一起。应当理解,可通过这种方式连接多于两个的联接器20,且任意单个联接器的第一夹持臂30或第二夹持臂40可与另外的联接器20的第一夹持臂30或第二夹持臂40在骨锚固件50上组合。任意数量的联接器20可沿患者脊柱的一侧或两侧植入。此外,根据患者的病理和身体构造,单元10可具有不同的机械特性。
在一些实施例中,本发明的稳定系统可允许连同其它运动节段的机能动态稳定一起使一个或多个椎骨运动节段融合。为此,稳定系统可包括例如如图11A所示的刚性的、促进融合的联接器101。刚性联接器101可构造成与前文描述的骨锚固件50、球支承件60和衬垫70一起使用。如图所示,刚性联接器101包括两个部件122、124,每个部件都以与前文描述的柔性联接器20类似的方式分别延伸到夹持臂130、140。每个臂130、140都包括开口132,该开口132用于以与关于柔性联接器20所述类似的方式附装于骨锚固件50。
如图11B进一步所示,两个部件122、124可彼此附装以允许对刚性联接器101的长度进行调节。例如,部件122、124可包括螺纹表面,刚性联接器101的长度可通过使一个部件122相对于另一部件124扭转而进行调节,与前面描述的用于调节柔性联接器20的长度的方式很相似。夹持臂130、140的每一个还可分别在下侧包括凹形腔穴134、144,该凹形腔穴构造成支靠在半球形的球支承件60上。这样,刚性联接器101到骨锚固件50上的植入类似于上文描述的柔性联接器20的植入。
如图11C所示,可提供刚性的、促进融合的联接器201的替换实施例。刚性的、促进融合的联接器201类似于刚性联接器101,不同之处在于它可不使用用于调节联接器201的长度的部件螺纹表面。刚性联接器201可构造成与前述骨锚固件50、球支承件60和衬垫70一起使用。如图所示,刚性联接器201包括两个部件222、224,该部件的每一个通过与前述柔性联接器20类似的方式分别延伸到夹持臂230、240。臂230、240中的每一个包括用于通过与关于柔性联接器20所述类似的方式附装到骨锚固件50上的开口(未示出)。每个夹持臂230、240还可分别在下侧包括凹形腔穴234、244,该腔穴构造成支靠在半球形的球支承件60上。
第一部件222和第二部件224可相对于彼此运动以便于调节联接器201的长度。作为螺纹表面的替换,部件222可包括腔穴226,该腔穴226构造成接纳紧固元件230以使第一部件222相对于第二部件224固定。因为第一部件和第二部件不包括螺纹表面,所以它们可通过使部件滑动而非扭转来相对于彼此运动。这个实施例允许外科医生在需要时现场调节刚性联接器201的长度。
紧固元件230可以是任何适当的紧固元件,例如螺钉或螺母。例如,紧固元件230可包括可断式螺母(break-away nut),该可断式螺母具有第一部分和第二部分,该第一部分构造成与部件222的部分226牢固地接合以固定第一部件222相对于第二部件的位置,第二部分构造成与用于将第一部分拧紧于刚性联接器的插入工具接合。可断式螺母的第二部分可以是可断部分,该可断部分具有较薄的壁或具有由较低屈服强度的材料制成的区域,且构造成在施加足够大的转矩时(即,当螺母230被充分拧紧时)断裂。腔穴226的内表面和紧固元件230的外表面可设置螺纹以有利于腔穴226与紧固元件230的接合。
如上所述,稳定系统可包括机能动态柔性联接器20和刚性联接器101,从而提供一种允许在患者脊柱的分离节段使运动保留和融合结合的模块化系统。通过允许刚性联接器101和柔性联接器20的可互换性,在该系统中,外科医生在满足患者的具体需求时将具有较大的灵活性。因此,一个脊柱节段可具有机能动态稳定(即,非融合),而相邻的节段可具有刚性的节段固定(即,融合)。
图12示出包括使用了柔性联接器20a、20b和刚性联接器101的三个分离的稳定单元10a、10b、10c的多节段系统12。单元10a和10c的柔性联接器20a、20b增加了患病运动节段的节段刚度并限制了屈曲、伸展、侧向弯曲和转动的运动范围,同时保留了运动。通过选择适当地设定尺寸的联接器20a、20b,后路节段高度也可被调节。此外,单元10b的刚性的、促进融合的联接器101提供刚性的节段固定,从而促进融合,同时使用了相同类型的骨锚固件50和器械。
模块化系统12具有多个优点。例如,如上所述,最初,被植入的系统可仅包括机能动态的柔性联接器20,该联接器20通过骨锚固件50连接到椎骨。但是,后来,由于疾病的发展、未减弱的疼痛、其它症状或患者病情的其它改变,可能需要融合一个或多个先前治疗过的(椎骨)水平。因此,在随后的外科手术中,外科医生可简单地用刚性联接器101代替先前植入的柔性联接器,同时仍能使用相同的骨锚固件。
如前文所述,本发明的单元和系统可使用微创的、肌肉非损伤的方法植入。这些方法可包括经皮方法或一系列使得组织受损最小化的小切割。
图13-19示出插入器械的示例性实施例,该插入器械可单独提供或与该系统一起作为一组提供。在本系统的一种示例性方法中,一系列克氏针200被插入到患者脊柱的椎弓根中。克氏针200可通过患者背部中的一系列小的切口插入。此外,如图13所示,可设置针模板202以辅助外科医生安置切口和克氏针200。如图所示,针模板202可包括与患者脊柱的椎弓根对准的预定开口204。开口204可在两侧设置成与待治疗的椎骨的两个椎弓根对齐。可设置不同尺寸的模板以与椎弓根间距有变化的患者相适应。
在插入克氏针200后,中空的骨锚固件50可从克氏针200上穿过,并且通过利用如图14A所示的一系列延伸杆220a、220b、220c,骨锚固件可植入选定的椎骨内。如图14B所示,延伸杆可附装于骨锚固件50的头部54以允许操纵锚固件50。此外,可设置扩张套管(dilatation sleeve)(未示出),延伸杆可穿过扩张套管以接近植入部位。在植入骨锚固件50后或在植入骨锚固件50期间,可利用延伸杆220来操纵骨锚固件50和所连接的椎骨以确定静态状况和加有载荷的情况下的总运动范围。这些信息有助于外科医生预测该脊柱节段所需的修正运动的可能范围。
如图15所示,可与器械组一起提供卡尺240。卡尺240可包括一对枢转臂242、244,各个臂分别延伸到指部接合开口246、248,且在相对端分别终止于夹持端250、252。枢转臂242、244可通过板簧254连接。如图所示,臂242、244的端部构造成利用底板256上的刻度标记258提供一对相邻的骨锚固件50之间的距离的读数或测量值。夹持端250、252可构造成保持每个骨锚固件50的球支承件60的一部分。这使得即使在骨锚固件50未平行安置或相对于彼此成特定角度时卡尺240也能起作用。
图16示出各种杆延伸部260,这些杆延伸部260构造成连接到锚固件的其它部件,例如球支承件60、衬垫70或螺母80。这些杆延伸部260的每一个都使得能对各个部件进行微创或经皮操纵。
一旦骨锚固件50就位且一对相邻骨锚固件50之间的距离已被确定时,外科医生便可选择用于安置在骨锚固件50之间的适当尺寸的机能动态柔性联接器20或刚性的促进融合的联接器101。可设置类似于图17示出的联接器长度调节器270以确保在插入前联接器的长度是适当的。如图所示,长度调节器270可包括体部272,该体部272具有一对夹持部271,在该对夹持部之间可保持联接器20、101。该对夹持部271形成联接器的插入区域274。在体部272内具有弹性加载机构,该弹性加载机构向夹持部271之一施加偏压力。可通过转动握把280来控制弹性加载机构,从而扭转联接器20、101并由此调节其长度。体部272还可包括窗口278,在该窗口内显示表示联接器长度的刻度标记276。尽管示出的是柔性联接器20,但是应当理解长度调节器270也可用于刚性联接器101。
然后,适当地设定尺寸的联接器20、101将沿克氏针200滑下并到达骨锚固件50的球支承件60上。随后,螺母80可用于将联接器20、101固定就位。在一些实施例中,螺母80可具有防止过度拧紧或未拧紧的特征。例如,图18A示出具有可断部分182的适当的螺母180的示例性实施例,可断部分将与骨锚固件接合的下部186连接到上部184。具有较薄的壁或具有由较低屈服强度的材料制成的区域的可断部分182构造成在施加了足够大的转矩时(即,当螺母180已被充分拧紧时)断裂。
螺母180可通过用于植入骨锚固件50和联接器20、101的微创方法插入。例如,图19示出用于插入螺母180的示例性插入工具290。该插入工具290包括长形体部292,该长形体部292从手柄部分294延伸至相对端的螺母联接端部296。如图18B所示,联接端部296可构造成在上部184牢固地附接到螺母,且与螺母相联的长形体部292可插入到先前限定的进入位置以将螺母180固定到骨锚固件50上。在被充分拧紧的情况下,螺母180将在可断部分182断裂,从而将下部186留在骨锚固件上并允许上部184移开。
外科医生可选择在邻近的(椎骨)水平重复此过程,直到患者脊柱的所有患病水平都被治疗。整个过程可经皮地和/或对周围组织微创地完成。
考虑到本说明书和本文所公开的本发明的实践,本发明的其它实施例对于本领域技术人员而言是显而易见的。本说明书和示例应被看作仅仅是示例性的,本发明的真正范围和精神由所附权利要求来限定。
