Description

一种人工颈椎椎体与椎间盘复合体 An artificial cervical vertebrae and intervertebral disc complex

技术领域 FIELD

[0001] 本实用新型涉及一种颈椎假体,特别是关于颈椎次全切除后保留颈椎双节段可活动的一种人工颈椎椎体与椎间盘复合体。 [0001] The present invention relates to a cervical prosthesis, in particular, is an artificial cervical vertebrae and intervertebral disc complex on cervical subtotal cervical double segment can be reserved activities.

背景技术 Background technique

[0002] 颈椎病的手术治疗分为颈前路椎间盘(或椎体次全)切除植骨融合术和颈后路单(或双)开门椎管扩大成形术。 [0002] Surgical treatment of cervical spondylosis is divided into anterior disc (or Vertebrae) resection of bone grafting and posterior cervical single (or double) door laminoplasty.

[0003] 颈椎前路椎间盘或椎体次全切除、椎体间植骨融合术是治疗颈椎病的经典手术方式,椎体次全切除就是手术时切除中间椎体(治病椎体,或称“责任椎”)的中央部分,约10〜12mm,同时切除上下两个椎间盘。 [0003] anterior cervical corpectomy or disc, interbody fusion is a classic surgical treatment of cervical spondylosis, corpectomy is the middle of the vertebral body resection surgery (treatment of vertebral, also known as "responsibility vertebral") of the central portion, about 10~12mm, while removal of the upper and lower disc. 椎间盘或椎体次全切除是解除脊髓、神经根压迫的关键步骤,植骨融合的目的则是填补椎间盘或椎体部分被切除后留下的空隙。 Disc or corpectomy is a key step to lift the spinal cord, nerve root compression, the purpose of fusion is to fill the gap left by the disc or vertebral body part to be cut. 采用这种手术方法,虽然脊髓、神经根压迫的问题解决了,但现行的植骨融合方法却会使颈椎的部分运动节段融合在一起而失去运动功能,如图1、图2所示,在中间一节椎体1上进行切除手术后,要想达到融合的目的,就必须使用螺钉4和钢板5将骨块6与三个节段的颈椎椎体固定在一起,这样三个节段椎体间必然失去了活动功能。 With this method of operation, although the spinal cord, nerve root compression solve the problem, but the existing methods but fusion portion causes the cervical motion segments fused together and lost motor function, as shown in FIG 1, FIG. 2, after surgery on the intermediate 1 a vertebrae, in order to achieve convergence, it is necessary to use the screws 4 and 5 the bone plate 6 together with the cervical vertebrae three segments, three segments so interbody activity is bound to lose the function. 因此,植骨融合其实是以牺牲颈椎的运动节段为前提的,是无奈之举,同时又是违背生物力学基本原理的手术。 So, in fact, at the expense of fusion of the cervical spine motion segment as a precondition, it is upset, but it is also contrary to the basic principles of biomechanics surgery. 但是,颈椎前路植骨融合手术已经应用半个多世纪,已经成为治疗脊髓型和神经根型颈椎病的“金标准”手术方式。 However, anterior cervical fusion surgery has been used over half a century, it has become the "gold standard" surgical treatment of spinal cord and nerve root type cervical spondylosis.

[0004] 临床经验与科学研究告诉我们,对于颈椎退行性疾病,我们治疗的并非整个疾病本身,而仅仅是这一疾病在特定部位造成损害的结果。 [0004] Clinical experience and research tells us that, for cervical degenerative disease, not the entire disease we treat in itself, but merely the result of damage caused by the disease in a particular area. 换言之,我们通过颈椎前路单个或多个节段的融合手术治疗好颈椎病时,颈椎退变仍然在继续,植骨融合手术除了会限制颈椎的运动以外,还会加速颈椎的退变,造成新的病损。 In other words, when we pass a single anterior cervical fusion surgery or multiple segments of good cervical spondylosis, cervical degeneration is continuing, and fusion surgery in addition to limit the movement of the cervical spine, but also accelerate the degeneration of the cervical spine, resulting in new lesions. 因此,颈椎次全切除手术后,保证颈椎的正常运动并有效防止相邻节段的退变成为脊柱外科医生寻求技术改进的新途径。 Therefore, cervical subtotal resection, to ensure the normal motion of the cervical spine and prevent adjacent segment degeneration into a new way of technological improvements sought for the spine surgeon.

[0005]本世纪初“人工颈椎间盘”(参考文献 1 =Goffin J,Casey A,Kehr P,et al. Prelim inary clinical experience with the Bryan cervical disc prosthesis[J]. Neurosurg, 2002,51 (3) :840-847)被设计并应用于临床,2003年引进我国,很多医院开展了这一新技术(参考文献2 :孙宇,潘胜发,张凤山,等.颈椎人工椎间盘置换术治疗颈椎间盘疾患的早期临床观察[J]·中国脊柱脊髓杂志,2006,16 (2) :85-98;参考文献3:王征,王岩,张雪松, 等.颈椎间盘假体置换术治疗脊髓型颈椎病的近期效果观察[J].中国脊柱脊髓杂志2006, 16 (6) :420-423),已经得到医学界的认可,最长随访6年的结果非常满意。 [0005] The beginning of this century "artificial cervical disc" (Reference 1 = Goffin J, Casey A, Kehr P, et al. Prelim inary clinical experience with the Bryan cervical disc prosthesis [J]. Neurosurg, 2002,51 (3) early Sun Yu, Pan Sheng-fa, Zhang Fengshan, such as cervical artificial disc replacement in the treatment of cervical disc disease:: 840-847) were designed and used clinically in 2003 to introduce our country, many hospitals to carry out this new technology (reference 2. clinical observation [J] · Chinese Journal of spine and spinal cord, 2006, 16 (2): 85-98; reference 3: Wang Zheng, Wang Yan, Zhang Xuesong, such as cervical disc prosthesis replacement therapy for cervical myelopathy short-term effect observation [J] Chinese Journal of spine and spinal cord 2006, 16 (6): 420-423), has been recognized by the medical profession, the longest follow-up of 6 years, the results are very satisfactory. 现行有效的一种“人工颈椎间盘”如图3、图4所示,它是由上终板7、下终板8以及中间的球形核9组成的。 Currently in effect a kind of "artificial cervical disc" in FIG. 3, FIG. 4, which is 7 by the upper endplate, lower endplate, and an intermediate spherical core 8 9 thereof. 球形核9嵌入到上终板7和下终板8中,因此,上终板7和下终板8就可以以球形核9为媒介相互转动了。 9 a spherical core 7 fitted into the end plate and the lower end plate 8, and therefore, the upper end plate 7 and the lower end plate 8 can be spherical core 9 is rotated another medium. 上终板7和下终板8分别连接在上节椎体和下节椎体上。 Upper end plate 7 and the lower end plate 8 are connected to the upper section and a lower section vertebrae vertebrae.

[0006] 虽然具有代表性的“人工颈椎间盘”置换非融合技术已经成为目前治疗颈椎病的最理想化的技术,但颈椎人工椎间盘置换的适应症是有限的。 [0006] Although a representative of "artificial cervical disc" replacement non-fusion technology has become the best of the treatment of cervical spondylosis, cervical artificial disc replacement but indications are limited. 第一,单纯颈椎间盘置换只适应于单节段椎间盘切除可以达到解除脊髓压迫目的的患者;第二,置换的前提是椎间隙没有塌陷,存留有椎间活动间隙。 First, the simple cervical disc replacement applies only to single segment discectomy can achieve the lifting of patients with spinal cord compression purposes; second, provided that the replacement of the intervertebral space does not collapse, remaining intervertebral space activities. 临床上很多退变较重的病人单纯切除椎间盘并不能解除对脊髓的压迫,由于椎体后缘增生不得不选择颈椎次全切除手术,最终将三个节段的颈椎椎体进行融合。 Clinically, many patients with severe degenerative disc excision alone does not relieve spinal cord compression due to vertebral hyperplasia had to choose cervical subtotal resection, eventually three segments of the cervical vertebrae are fused.

[0007] 多节段融合手术比单节段融合术更易使颈椎相邻节段的退变加速,这一点已经被证实。 [0007] Multi-segmental fusion surgery than a single segment of cervical spine fusion more adjacent segments accelerate degeneration, it has been demonstrated. 因此,设计一种颈椎次全切除手术后仍能保持颈椎椎体运动的假体是十分必要的。 Therefore, the design of a cervical times after total resection prosthesis can maintain cervical vertebrae movement is very necessary.
