The overall structure of the posterior cervical vertebra plate clamp is in a bridge shape, the posterior cervical vertebra plate clamp is composed of a connecting plate mainly of a supporting structure, an inner clamping plate and an outer clamping plate, the inner clamping plate and the outer clamping plate are arranged on the two sides, and fixed tooth and fixed holes are arranged on the inner clamping plate and the outer clamping plate respectively. The posterior cervical vertebra plate clamp can be used for auxiliary treatment of cervical spondylotic myelopathy, congenital cervical spinal stenosis, multi-segmental cervical degeneration with spinal canal stenosis, ossification of posterior longitudinal ligaments, excessive cervical lordosis and other diseases. Compared with a traditional nail rod system and an unilateral door opening fixing system, surgical risks can be effectively reduced, the surgical process can be effectively simplified, the problem that vertebral plate expanding forming postoperation stability is poor can be solved successfully, the phenomenon that a door is closed after the two sides of the door is opened is avoided, and the spinal cord is protected against compression of the outside after the door is opened.

Description

颈椎后路椎板夹 Posterior cervical laminectomy clip

技术领域 FIELD

[0001] 该发明涉及一种医疗器械技术领域,具体涉及一种颈椎后路椎板成形椎管扩大术的颈椎后路椎板夹。 [0001] The invention relates to a technical field of medical devices, particularly, to a posterior cervical laminoplasty posterior cervical spinal lamina augmentation folder.

背景技术 Background technique

[0002] 颈椎病是骨科常见病、多发病。 [0002] orthopedic cervical disease is a common disease. 对脊髓型颈椎病,发育性颈椎管狭窄症,长节段后纵韧带骨化症或黄韧带骨化症,颈椎多节段退行性改变,以及颈椎病前路减压不满意未使症状缓解者,临床上多采用颈椎后路椎板成形椎管扩大术。 Cervical spondylosis myelopathy, cervical stenosis development, the long segment OPLL or ligamentum flavum, degenerative changes in the cervical spine multiple segments, and anterior decompression cervical spondylosis symptomatic relief not satisfied who use more clinical posterior cervical laminoplasty spinal augmentation. 自1970年日本开展后路颈椎椎板成形术以来,单开门颈椎扩大成形术已被公认为治疗颈椎管狭窄症最有效的方法之一。 Since Japan to carry out posterior cervical laminoplasty 1970, single-door cervical expand angioplasty has been recognized as one of the treatment of cervical stenosis most effective way. 但传统的单开门手术存在术后椎管再狭窄以及轴性症状等缺点而限制了其推广。 However, the traditional single door after spinal surgery disadvantage axial symptoms of restenosis and the like and limit its promotion.

[0003] 近年来寻求一种操作简便,固定可靠且疗效满意的改良单开门手术固定方式成为新的研究热点,成而涌现出以Certerpiece钛板为代表的多种颈椎单开门固定板。 [0003] In recent years, seeking a simple, fixed reliable and satisfactory outcome of modified open door surgical fixation has become a new hotspot, and emerged into a titanium plate to Certerpiece represented a variety of cervical open-door fixed plate. 上述颈椎单开门固定板中都只对开门侧进行固定,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,因此其抗疲劳性能较差, 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。 Cervical spine above the door fixing plate of the door-side fixing only, and are not simultaneously fixed lamina and side block side door shaft, not integrally formed, they failed to form a physiological whole posterior cervical spinal anatomy reconstruction, Thus its poor fatigue properties, can not effectively disperse the pressure from directly behind the cervical spine, may occur under certain physiological spinal loading pressure and then close the door after molding, leading to surgical failure.

发明内容 SUMMARY

[0004] 为解决上述问题,本发明的目的是提供一种手术操作简单易行、能为颈椎后路椎管扩大成形术后椎管实现稳定性重建的颈椎后路椎板夹。 [0004] In order to solve the above problems, an object of the present invention is to provide a simple surgical operation, can laminoplasty for stability after spinal reconstruction posterior cervical posterior cervical lamina is sandwiched. 上述颈椎后路椎板夹采用一体化设计、整体结构呈桥型,能够解决椎板扩大成形术后稳定性差的问题、防止双开门后再关闭的现象发生、保护开门后脊髓不受外界压迫。 Above posterior cervical laminectomy clip with integrated design, the overall structure was the bridge type, to address the expansion of the lamina forming after poor stability, prevent double-door then closed phenomenon, protecting the spinal cord to open the door from outside oppression.

[0005] 为了实现上述目的,本发明的技术方案是提供一种颈椎后路椎板夹。 [0005] To achieve the above object, the technical solution of the present invention is to provide a clip posterior cervical lamina. 上述椎板夹整体结构呈桥型由主要起支撑结构的连接板和两侧内外夹板组成,内外夹板上均设有固定齿和固定孔、正常情况下固定齿即可为术后提供必要稳定性,若在术中为内夹板所开通道过大稳定性不足时可从固定孔内压入固定钉。 Above lamina sandwiched by the bridge as a unitary structure from a support structure of the primary web and inner and outer sides of splint, the splint has both inside and outside the fixing hole and fixed teeth, the fixed teeth to provide the necessary stability under normal conditions after when the jaws within the channels over the opening in the surgery may be press-fitted into the fixing hole from the staple large insufficient stability. 同时本发明提供多种形式的技术方案,植骨型椎板夹可进行骨质回植、锁定型椎板夹可根据需求在术中使用锁定螺钉进行固定。 Meanwhile, the invention provides various forms of technical solutions, may be interposed bone graft type bone lamina replantation, lamina-type locking clip may be secured according to needs surgery using a locking screw.

[0006] 上述颈椎后路椎板夹结构简单、加工易实现,植入过程更加安全、简便,对患者创伤更小,同时缩短手术时间、降低手术风险。 [0006] The posterior cervical laminectomy folder structure is simple, easy to implement process, the implant procedure more secure, convenient, less invasive for patients, while reducing operation time and reduce the risk of surgery. 可用于脊髓型颈椎病、先天性颈椎管狭窄、多节段颈椎退变伴椎管狭窄、后纵韧带骨化症、颈椎前凸过度等病症的辅助治疗。 It may be used for cervical myelopathy, congenital cervical stenosis, multilevel cervical degeneration with spinal stenosis, ossification of posterior longitudinal ligament, adjuvant treatment of conditions such as excessive cervical lordosis. 相比传统的钉棒系统和单侧开门国定系统能够有效的降低手术风险、简化手术过程,可以成功的解决椎板扩大成形术后稳定性差的问题、防止双开门后再关门的现象发生、保护开门后脊髓不受外界压迫。 Compared to traditional screw system and open the door on one side of a national system can effectively reduce the risk of surgery, simplifying the surgical procedure can be successfully resolved the expansion of the lamina forming after poor stability, prevent double-door then closed the phenomenon, protection after the spinal cord to open the door from outside oppression.
