技术领域 FIELD

[0001] 本实用新型涉及一种医疗辅助器械,特别针对颈椎管狭窄疾病患者进行后路单开门椎管扩大成形术失败的问题,设计的一种适用于颈椎后路单开门椎管扩大成形术的颈椎通用全椎板-双侧块桥接板。 [0001] The present invention relates to a medical device, especially for a patient for posterior cervical spinal canal stenosis disease single door angioplasty failure problem, a design suitable for posterior cervical open-door laminoplasty General cervical laminectomy - bilateral block bridge board.

背景技术 Background technique

[0002] 针对颈椎管狭窄,良好的手术疗效有赖于手术方式的正确选择和对脊髓的充分减压。 [0002] For cervical spinal stenosis, a good way of surgery depends on the proper selection and surgical decompression of the spinal cord. 颈椎管扩大成形术是既能治疗颈椎管狭窄又可完好地保留椎板的最有效方法之一,尤其是单开门椎管扩大成形术,因其具有较多的优点在临床上应用广泛。 Cervical canal expansion angioplasty is not only for treatment of cervical stenosis in turn one of the most effective methods intact lamina retention, especially single-door laminoplasty, because it has the advantage of more widely used in clinical practice. 对于先天性发育性颈椎管狭窄、多节段后纵韧带骨化及前路手术减压效果不明显等情况,手术治疗多采用颈椎后路单开门椎管扩大成形术,手术过程中需要对开门侧的椎板进行固定并重建椎管。 For congenital cervical stenosis, ossification of posterior longitudinal ligament and anterior decompression effect is not obvious after multiple segments, etc., surgical treatment of multiple posterior cervical open-door laminoplasty, the need for open surgical procedures side fixing lamina and spinal reconstruction. 目前临床上常见的固定、重建材料主要为颈椎单开门固定板,但只在开门侧进行固定,并没有同时固定门轴侧椎板和侧块,无法形成一个整体,未能从整体解剖结构上形成生理性颈椎后路椎管重建,因此其抗压性能较差,无法有效分散来自颈椎正后方的压力,可能在一定的生理压力负荷下发生椎管成形术后开门再关闭,导致手术失败。 Current common fixed reconstruction materials major clinical cervical single door fixing plate, but only in the side door opening is fixed, and not while fixing lamina and side block side door shaft, can not form a whole, the overall anatomy from failed forming posterior cervical spinal physiological reconstruction, so its compression performance is poor, can not effectively disperse the pressure from directly behind the cervical spinal open and close the angioplasty may occur under certain physiological load pressure, resulting in operation failure. 此外,目前使用的后路固定板手术操作步骤繁琐,不适用于同时固定开门侧和门轴侧。 In addition, the use of posterior fixation plate current complicated surgical procedure, while not applicable to the fixed-side door and the door-side axis.

[0003] 根据申请人所进行的资料检索,迄今为止,目前存在的固定板均没有最大化的实现颈椎后路单开门椎管扩大成形术后椎管稳定性重建,且目前存在的固定板其易用性和通用性并不理想,最终的手术效果也难以实现颈椎后柱的生理性重建。 [0003] According to the information retrieval performed by the Applicant, so far, the existing fixing plate are not maximized to achieve posterior cervical canal open-door laminoplasty stability reconstructive surgery, and the fixing plate which existing ease of use and versatility is not ideal, the ultimate effect is difficult to achieve surgical reconstruction after cervical spinal column. 申请人设计的拱桥形通用颈椎椎板-侧块桥接板,同时兼顾了稳定性和易用性,实现了颈椎后柱的仿生性重建。 Applicant arch-shaped design universal cervical laminectomy - bridging block side plate, taking into account the stability and ease of use achieved biomimetic reconstruction of the cervical column.
