Description

脊椎固定用旋控式固定装置
                        技术领域
本发明是为一种脊椎固定用旋控式固定装置,其是为一种采用旋转控制方式来对脊椎固定杆或钉进行固定的装置。
                        背景技术
由外科手术在脊椎侧设置固定杆的结构被发展完成已有相当长的时间,该类设计亦为外科医师及相关患者提供了一项良好的选择,其运用方式相当多,诸如:本发明人先前发展完成的第81217786号[一种中央杆式脊椎固定复位系统](U.S.Pat.No.5,387,212 VERTEBRALLOCKING AND RETRIEVING SYSTEM WITH CENTRAL LOCKINGROD)及第84202032号[中央双杆式脊椎固定复位装置](U.S.Pat No.5,582,612 VERTEBRAL FIXING AND RETRIEVING DEVICE HAVINGCENTRALLY TWO FIXATION)专利案中所揭露的。
为了提供适用于脊椎固定杆与其他构件间的固定结合,本发明人亦曾发展出了第82211220号[一种脊椎固定杆用扣夹装置](U.S.Pat.No.5,380,326 CLAMPING DEVICE FOR VERTEBRAL LOCKINGROD),其结构如图11所示,同时在美国亦有人发展出了运用相同技术手段的U.S.Pat.No.5,476,462 SPINAL IMPLANT SYSTEM。其结构如图12所示。
在图11中所示的结构是包括:一具U形开口的外扣夹部件80与一内扣夹部件85,在该外扣夹部件80内具有一微斜凹榫82,内扣夹部件85外侧则设有相配合的微斜凸榫86,当组装时是先将固定杆容置在外扣夹部件80的U形开口中,然后将内扣夹部件85采用滑移的方式组合至外扣夹部件80中,并借助由凹、凸榫的配合,提供固定杆适合的夹持固定作用。
在图12中所示的美国专利案亦采用雷同的技术手段,其操作方式及实现的功效均如出一辙,其亦是设置有一外扣夹部件90及一内扣夹部件95,在外扣夹部件90内侧设有一微斜的凹槽,在内扣夹部件95外侧设置成微斜的外表面,当二者相套合时,即可提供固定杆适合的夹持固定作用。
前述的二种固定装置均是用以提供固定杆夹持固定的作用,但在实际操作中却发现其仍存在一些瑕疵而有待改进:
1.其组装时是由侧面进行组装,亦即在手术进行中必须拥有较大的空间才能够方便的进行组装,此即造成手术进行时空间的运用效率。
2.当其组装至最后阶段时,固定装置与固定杆间已然形成相贴靠的状态,为了提供良好的夹持固定效果,必然要将内扣夹部件推抵至外扣夹部件中的定位,此时即有可能带动固定杆产生一些位移,该位移即有可能影响到手术结果的完美与否,尤其是在该固定装置扣夹至定位时,固定杆已然被定位而无法再进行调整,此一缺陷确有待解决。
                       发明内容
本发明的主要目的在于:提供一种脊椎固定用旋控式固定装置,其是以一固定座与一固定块相配合,而可以旋控的方式对夹设其间的固定杆或钉进行压制固定,以达到方便操作与稳固固定的功效。
本发明一种脊椎固定用旋控式固定装置,其包括:
一固定座,其具有一呈U字型的凹沟,该凹沟是供脊椎固定杆或钉穿过,在凹沟两侧壁内侧设有相对的扣槽;
一固定块,在固定块周围设有与固定座扣槽相配合的凸出的扣缘,该扣缘的两相对侧设有切面,在固定块底面设有凸出的压制弧面,固定块顶面设有旋控端。
所述的在该固定座凹沟两侧壁外侧设有供工具夹持的夹槽。
所述的该固定块旋控端是为一外六角头端;所述的该固定块旋控端是为一内六角头端。
所述的在该固定块旋控端底面设有一圈限位槽,且在固定座凹沟两侧壁的顶缘设有凸出的限位片。
所述的在该固定块压制弧面中央平行切面的方向设有一组装凹弧,垂直组装凹弧的方向上设有一固定凹弧,该组装凹弧深度深,固定凹弧的深度浅。
所述的在该固定块压制弧面的组装凹弧与固定凹弧之间设有调整凹弧,该调整凹弧的深度介于组装凹弧与固定凹弧之间。
所述的该固定座下方一体成型有固定螺丝。
所述的该固定座下方一体成型有钩夹。
所述的该固定座下方设置枢接装置,其是在固定座下方形成孔座,一球头组装在孔座中,并在固定座中的球头上方组装一压制环。
所述的该固定座下方设置枢接装置,其是在固定座下方设有一偏向的孔座,由孔座下方以一组装环将压制环与球头组装在孔座中。
所述的该球头下方一体成型有固定螺丝。

                       具体实施方式
请参阅图1所示,其是为本发明的第一较佳实施例元件分解示意图,其中可以见到本发明包括:
一固定座10,其上具有一呈U字型的凹沟12,该凹沟12是供脊椎固定杆30穿过,在凹沟12两侧壁内侧设有相对的扣槽14,在凹沟12两侧壁外侧设有供工具夹持的夹槽16,另在凹沟12两侧壁的顶缘设有凸出的限位片18;
一固定块20,在固定块20周围设有凸出的扣缘22,该扣缘22的两相对侧设有切面220,在固定块20底面设有凸出的压制弧面24,固定块20顶面设有旋控端26;
由图2所示,其是为本发明的第一较佳实施例固定块20底面结构示意图,其中可以见到本发明的固定块20底面压制弧面24的结构,在该压制弧面24中央平行切面220的方向设有一组装凹弧面240,垂直组装凹弧240的方向上设有一固定凹弧244,而在组装凹弧240与固定凹弧244之间设有调整凹弧242;其中组装凹弧240深度最深,固定凹弧244的深度最浅,而调整凹弧242的深度介于二者之间。
在此实施例中的固定块20旋控端26是为一外六角头端260,在其底面设有一圈限位槽262。
配合图2所示,其是为本发明的第一较佳实施例组合示意图,当本发明在组合时,是先将固定杆30容置于固定座10凹沟12中,然后将固定块20置入固定座10凹沟12中,由于固定块20扣缘22相对侧的两切面220间宽度是与固定座10的凹沟12相配合,而可让固定块20方便的置入固定座10凹沟12中,在固定块20置入凹沟12中定位时,其压制弧面24的组装凹弧240贴靠在固定杆30上,并令其扣缘22的位置恰对正固定座10的扣槽14,此时即可以通过适当的工具经旋控端26将固定块20加以旋转,当固定块20旋转后,可让扣缘22扣入固定座10扣槽14中,并由压制弧面24对固定杆30进行压制,当固定块20旋转至调整凹弧242贴靠固定杆30时,固定杆30已略被压制,但仍未达迫紧固定的程度,故而操作人员仍可将固定杆30作适当的位置调整,而当固定杆30调整至定位后,即可将固定块20再作旋转,而令固定凹弧244贴靠固定杆30,令固定杆30被稳固的夹持在固定座10凹沟12与固定块20固定凹弧244之间(如图4中所示)。
另在图4中可以见到本发明的固定块20组装入固定座10凹沟12中定位时,设置在固定块20旋控端26底面的限位槽262可套设在固定座10限位片18外侧,而再提供另一份固持效果。
接下来由图5所示,其是为本发明的第二较佳实施例元件分解示意图,其中可以见到此一实施例的整体结构配置与前述第一实施例雷同,但该固定块20的旋控端26为一内六角头端264,同时在此实施例的固定座10上没有限位片18,在固定块上亦没有限位槽262。
配合图6的本发明第二较佳实施例组合示意图所示,此一实施例的结构在使用时与前述第一较佳实施例相同,但由于此一实施例是将旋控端26采用内六角头端264的设计,故而能够将组合完成后的高度降至更低的程度,而可让整体所占用的空间更少。
在前述的二实施例中的固定座10下方可一体成型有固定螺丝17(如图6中所示),亦可搭配如第81216259号[脊椎钩夹固定复位装置](U.S.Pat.5,439,463)中所示的钩夹来运用,而发挥其实用性的功效。
再由图7所示,其是为本发明的第一较佳实施例搭配装置40运用的实施例元件分解示意图,由图中所示可知,本发明亦可在固定座10下方设置枢接装置40,其是在固定座10下方形成孔座19,而可将一具有球头420的固定螺丝42组装在孔座19中,并于固定座10中的球头420上方组装一压制球422,当固定杆30组装入固定座10凹沟12中时,该固定杆30可贴靠在压制坏422上方,而由压制环422来压制球头420,因此,可让固定30与压制环422间呈线接触,而较已知此类枢接装置以固定杆直接压制球头的点状接触更为稳固。
在图8中所示的,是为本发明的第一较佳实施例搭配枢接装置40运用的组合剖面结构配置示意图,其中可以看出本发明以固定座10搭配枢接装置运用的组装完成状态,其可由固定块20压制固定杆30,再由固定杆30经由压制环422来压制球头420,整体结构搭配完美,确为一杰出的设计。
图9中所示的,是为本发明的第一较佳实施例搭配另一型式枢接装置50的组合剖面示意图,其中可以见到在该固定座10下方设有一偏向的孔座19,故而其可由孔座19下方搭配一组装环52来组装压制环422与球头420,如此亦可实现相同的功效。
再由图10所示,其是为本发明的另一较佳实施例元件分解示意图,其整体的结构配置与图1中所示的第一较佳实施例雷同,但在该固定块20上可设置一固定螺孔28,而可在固定块20组装至固定座10上定位后,再将一固定螺丝280螺合在固定块20固定螺孔28中,而对固定杆30提供另一份压制固定作用,让整体的固定效果得到多重的保障,发挥更佳的实用性。
以上的说明及附图中所列举的实施例中均是以固定杆30为例作的说明,但本发明亦可运用在脊椎固定钉的固定配合,而可达到相同的固定功效。
