Description

自适应浮动组合颈椎椎间融合器 Floating adaptive combination cervical fusion cage

技术领域 FIELD

[0001] 本发明涉及一种椎间融合器,特别是涉及一种自适应浮动组合颈椎椎间融合器。 [0001] The present invention relates to an intervertebral fusion device, particularly relates to an adaptive combination of floating cervical fusion cage.

背景技术 Background technique

[0002] 脊髓型颈椎病和神经根型颈椎病是中老年人群的常见病、多发病,随着生活方式的改变,其发病率也逐年提高,并且呈现出年轻化的趋势。 [0002] cervical myelopathy and radiculopathy cervical spondylosis is a common disease in the elderly population, the disease, with lifestyle changes, the incidence rate has increased year by year, and is showing a trend of younger age. 颈椎病的致病机理是颈椎间盘退变后向后突出、或锥体后缘骨质增生形成骨赘压迫颈椎管内的脊髓和神经根,由于脊髓组织内的神经细胞非常脆弱,压迫所引起的缺血缺氧等病理改变导致的神经功能丢失不可逆转。 Pathogenesis of cervical disease is cervical disc degeneration and the rearwardly projecting, cone or the edge formed hyperostosis spinal cord and nerve roots in the cervical osteophyte compression, since the nerve cells in the spinal cord tissue is very fragile, due to compression ischemia and hypoxia and other pathological changes in nerve function loss caused irreversible. 因此对于脊髓型颈椎病应早期手术治疗解除压迫,对于症状严重的根性颈椎病也应采取积极手术治疗。 So for cervical myelopathy should relieve pressure early surgical treatment for cervical radicular symptoms of severe disease should also take active surgical treatment. 颈椎前路减压植骨融合术(简称ACDF)是目前临床上治疗脊髓型颈椎病和神经根型颈椎病的标准手术方法。 Anterior cervical decompression and fusion surgery (referred to ACDF) is the current standard surgical treatments for cervical myelopathy and radiculopathy cervical disease clinic. 其原理是经颈椎前方切除的椎间盘、增生的骨赘、甚至整个狭窄节段的锥体,切除致压结构后,于病变的上下节之间植入支撑骨块或椎间融合器(Cage),以维持椎间的高度和矢状序列。 The principle is excised cervical disc through the front, the proliferation of osteophytes, and even entire narrow cone segments, caused by pressure after the removal of the structure, the supporting bone implant or intersomatic cage (Cage) between the upper and lower sections of the lesion to maintain height and sagittal sequences intervertebral.

[0003] 对于低位颈椎手术,椎间融合器加钢板固定的方式使用比较方便。 [0003] For the lower cervical spine surgery, interbody fusion cage plate fixed manner more convenient to use. 以往的手术采用的是单一的椎间融合器和单一的钢板进行固定,椎间融合器没有与钢板进行固定,具有融合器移位和不融合的风险,导致手术失败。 Conventional surgery using a single intervertebral cage and a single fixed plate, the cage is not fixed and the steel sheet, and having no risk of the shift fusion fusion, leading to surgical failure. 现有另一种椎间融合器,将钢板与融合器固定在一起使用,钢板上设有固定孔,通过固定孔和螺钉将融合器固定,此种固定方式虽然能够较好的限定融合器的位置,但是钢板与融合器之间不具有一定相对浮动空间,无法调试,导致不能保证与上下相邻锥体的骨面紧密贴合,严重影响手术疗效。 Another conventional intervertebral cage, the cage plate and secured together using a fixing plate holes, and fixing holes through the fixing screws fusion, although such fixing means can be better defined fusion device position, but does not have a certain space between the plate and the relative floating cage, can not debug, resulting in no guarantee that the bone surface and the adjacent upper and lower cone snug fit, seriously affecting the surgery. 另外,将钢板固定在融合器上之后,在植入时,需要更大的手术切口,不仅手术创伤大,而且操作难度较大,增加患者的伤痛。 Further, after the plate is fixed to the cage, when implanted, a larger incision, only surgical trauma, and difficult operation, increasing patient pain.
