Description

一种固定装置和脊柱系统
本申请是申请日为2014年9月10日、申请号为201410456862.5、发明名称为“具有尖状物的椎体护架”的中国专利申请的分案申请。
技术领域
本发明涉及的椎体护架(cage)是治疗颈椎或脊椎的椎间盘疾病、椎间盘手术、脊髓症、骨折等时，插入于颈椎骨或脊椎的椎体之间，更加详细地说是涉及具有尖状物的椎体护架，上部尖状物与下部尖状物分别向本体的上下部展开，其中上部尖状物与下部尖状物附着在进入椎体护架本体内部的夹子，展开的上部尖状物与下部尖状物挂在位于椎体护架上下的颈椎骨或脊椎骨的椎体，进而椎体护架锁定并固定在椎体之间。
背景技术
一般地说，在整形外科或神经外科为了治疗颈椎或脊椎的椎间盘疾病(cervicaldisc disease)、椎间盘、脊髓症、骨折等实施手术，其手术是去除患部的椎间盘解除神经压迫之后，插入人工纠正体的椎体护架(cage)，复原及保持去除椎间盘部分的间隔。
这种椎体护架在患者活动时施加应力的影响下，存在其在椎间空间内活动的危险性，因此应具有防止护架转动(pivot)的同时还防止在椎间空间内颈椎或脊椎相互间活动的手段。
为此，韩国专利公开第10-2011-33707号的颈椎体之间的融合机器、韩国专利第900991号的用于植入脊椎的脊椎护架、韩国专利公开第10-2011-11049号的脊椎体间融合护架及其构成，公开了在去除椎间盘部位插入椎体护架之后，利用螺栓将具有规定长度的用于加固的板件固定在颈椎或脊椎，进而防止产生插入的椎体护架的变位。
但是上述的公知技术是，在所有护架的前方部分通过螺栓固定用于加固的板件的方式，因此插入于板件的螺栓头部分或板件的一部分，更凸出于位于设置椎体护架的去除椎间盘部位的上下位置的脊椎或颈椎的凸出部位，根据随着时间经过的同时患者在活动时施加的力，护架在椎间空间内移动或转动(pivot)，同时存在在椎间空间内凸出的螺栓头部分与通过脊椎或颈椎的血管组织或神经组织接触的可能性，因此仍然需要开发更加安全的护架。
另外，所述的公知技术为了固定椎体护架而使用板件与螺栓，但是在狭窄的空间利用螺栓固定板件过程，不仅难度高还需要高度的注意力，因此是对手术者的手术熟练度要求很高。
发明内容
(要解决的课题)
本发明作为为解决如上所述的现有的问题而提出的，本发明提供具有尖状物的椎体护架构成的技术课题在于，防止产生如同现有的螺栓凸出部位，在做椎体护架手术时与通过脊椎或颈椎的血管组织或神经组织的干涉最小化，比较简单并且单纯地执行为了固定椎体护架的手术，可提高手术的稳定性。
(解决问题的手段)
为达成如上所述的技术课题，本发明的具有尖状物的椎体护架构成的特征在于，上部尖状物与下部尖状物分别向本体的上下部展开，其中上部尖状物与下部尖状物附着在进入椎体护架本体内部的夹子，展开的上部尖状物与下部尖状物挂在位于椎体护架上下的颈椎骨或脊椎骨的椎体，进而椎体护架锁定并固定在椎体之间。
(发明的效果)
具有如上述构成的本发明的具有尖状物的护架具有效果如下。
首先，本发明椎体护架根据在分别向椎体护架的架体上部及下部展开的尖状物，椎体护架固定并挂在椎间盘去除部位的颈椎骨或脊椎骨的上下侧椎体，因此具有大幅度减少如现有的产生干涉可能性的效果，其中产生的干涉是固定椎体护架的螺栓或板件的一部分与通过设置椎体护架的椎间盘去除部位的脊椎或颈椎的神经组织与血管组织的干涉，进一步具有更加改善患者的椎间盘相关疾病的术后治疗的效果。
另外，本发明椎体护架不采用如同现有的板件或螺栓，并且其本身具有尖状物，因此省略现有的在非常狭窄的椎间空间上用螺栓固定板件的难度高并且繁琐的手术过程，不仅可提高手术的便利性还提供比较单纯化的手术过程，进而是具有也可改善手术稳定性效果的非常进步的发明。

另一方面，在所述导块40的前面板41上至少形成一个以上的凹陷孔45，其中所述凹陷孔45插入于在待后述的插入机构200的头部210固定的结合螺栓(未图示)。
参照图12的操作状态，详细说明如上述构成的本发明椎体护架10的操作。
图12a是夹子进入时的立体图，图12b是夹子进入时的平面图，图12c是尖状物未展开状态的H-H'线断面图，图12d是尖状物展开状态的断面图。
本发明椎体护架10的操作使所述上部尖状物20与所述下部尖状物30分别挂在椎间盘去除部位的颈椎骨或脊椎骨上下侧椎体，同时固定椎体护架10。
首先，如图12a及图12b所示结合本体10与导块40，在其状态利用待后述的插入机构200等工具推动结合上部尖状物20与下部尖状物30状态的夹子50的右侧挂块52与左侧挂块52，通过所述导块40的进入口46将夹子50进入本体10内部。
在这种夹子50的进入初期的状态，所述上部尖状物20与下部尖状物30的上部刀刃21与下部刀刃31，只到达本体10内部的倾斜部140的上部倾斜面141与下部倾斜面143的入口，同时如图12c所示处于未向本体10的上面101与底面104外部展开的状态。
接着，若将如上所述进入的夹子50再推向本体10内部，则如图12d所示引导结合于夹子50的上部尖状物20与下部尖状物30，沿着在本体10内部形成的倾斜部140的上部倾斜面141与下部倾斜面143，同时分别向上方及下方移动向本体10的上面101与底面104外部凸出，直到根据在所述倾斜部140的中央形成的凸出面146挂住夹子50的基座57，上部尖状物20与下部尖状物30分别向上方及下方移动的同时展开。
这时，所述夹子50右侧肋条53及左侧肋条54向倾斜部140的上部平面142上滑动，挂住所述夹子50右侧肋条53及左侧肋条54，所述夹子50的下部肋条55向倾斜部140的下部平面144上滑动，挂住所述夹子50的下部肋条55。
因此，本发明椎体护架1根据执行如上所述的展开动作的上部尖状物与下部尖状物，可省略在狭窄的椎间空间上的用螺栓固定板件的难度高并且繁琐的手术过程，可提高手术的便利性改善手术稳定性。

具体地说，参照图13a的立体图、图13b的平面图、图13c的尖状物未展开状态的侧面图，为了本发明椎体护架1的插入机构200，根据插入于导块40的前面板41的凹陷孔45的结合螺栓(未图示)，具有与导块40结合的头部210。
所述头部210大致为六面体形状，第1下部支撑棒220的一侧结合于头部210的左侧，第2下部支撑棒230的一侧结合于头部210的右侧。
另外，推杆240位于所述第1下部支撑棒220与第2下部支撑棒230之间，其中在所述推杆240一侧末端形成将向本体10内部推动所述夹子50的凸台(boss)243。
所述推杆240由形成在其另一侧末端的按板241，与从按板241延长的棒体242，与连接所述棒体242与所述凸台243的结合口244构成，若向前方推动按板241，则通过棒体242向前方移动连接于结合口244的凸台243，同时如图13d将夹子50进入椎体护架1的本体10内部，上部尖状物20及下部尖状物30分别向本体10的上面与底面外部凸出展开。
为了这种操作，所述头部210在结合所述第1下部支撑棒220的左侧头部211，与结合所述第2下部支撑棒230的右侧头部212之间，所述推杆240的凸台243在所述左侧头部211与右侧头部212之间可向前方或后方移动，并且所述第1下部支撑棒220的另一侧末端及所述第2下部支撑棒230的末端，内插到挂住所述推杆240的棒体242的推杆导件221内部。
另外，向所述插入机构200的头部210的上侧形成上部头部213，所述上部头部213内插上部支撑棒250的一侧末端，所述上部支撑棒250的另一侧末端内插到在所述推杆导件221上部形成的上部支撑棒导件251内部，同时在所述上部支撑棒250的一侧末端安装支撑体252。
所述上部支撑棒250与在插入夹子50时做椎体护架1手术的脊椎或颈椎的上侧椎体接触，执行提高插入机构400固定性及稳定性的功能。
图14是将本发明椎体护架手术到椎间盘去除部位的断面图。图示了手术状态，本发明椎体护架1位于颈椎或脊椎骨上侧椎体D1与下侧椎体D2之间之后，通过如上所述的插入机构200将夹子50进入本体10内部，向本体10的上面101及底面104的外部凸出上部尖状物20及下部尖状物30，进而凸出的尖状物20、30末端的上部刀刃21与下部刀刃31的尖端部，挂在位于椎体护架1上下的上侧椎体D1与下侧椎体D2，从而椎体护架1锁定并固定在椎体D1、D2之间。
在实际手术时为了将所述夹子50进入本体10，利用用于手术的锥子(未图示)等锤击在推杆240另一侧末端形成的按板241，同时将夹子50慎重并慢慢地进入本体10内部。
因此，本发明的椎体护架1如图所示在上侧椎体D1与下侧椎体D2之间，向其椎体D1、D2内侧后方巩固地固定上部尖状物20与下部尖状物30，进而可大幅度减少有现有的引起椎体护架具有的螺栓或板件的一部分与通过设置椎体护架的椎间盘去除部位的脊椎或颈椎的神经组织与血管组织的干涉的可能性。
在以上的说明参照附图详细说明了具有尖状物的护架的构成，但是根据技术人员本发明可进行多样的修改、变更及替换，这种修改、变更及替换应解释为属于本发明保护范围。
