技术领域 FIELD

[0001] 本发明涉及医用生物植入材料和医疗器械领域,具体涉及可诱导DBM复合颈椎间隙融合同种骨垫及配套工具。 [0001] The present invention relates to the field of biological medical implant materials and medical instruments, particularly to a composite DBM inducible isoform cervical vertebra bone fusion and support pad tool.

背景技术 Background technique

[0002] 颈椎病、颈椎间盘突出、颈椎外伤滑脱或者骨折是临床常见病,也是一种危险病例,严重的会出现截瘫或者部分截瘫。 [0002] cervical spondylosis, cervical disc, cervical spine injuries or slip fracture is a common disease, but also a dangerous case, there will be severe paraplegia or partial paraplegia. 无论是颈椎病或者是外伤滑脱等严重颈椎问题,均需要行颈椎间隙融合手术,即在颈椎间隙植入骨材料,使颈椎间隙骨性愈合,从而恢复颈椎的稳定性,防止神经和脊髓压迫加重。 Whether trauma or cervical spondylosis cervical serious problems such as slipping, require clearance cervical fusion procedures, i.e., bone implant materials of cervical vertebra, cervical vertebra bone healing so to restore the stability of the cervical spine, to prevent nerve and spinal cord compression aggravated . 而传统在椎间隙植入病人自体骨可导致病人的取骨区并发症等缺点,现有技术植入金属或者其它人工材料存在生物相容性差,植入材料不能形成新骨或者成骨能力差,不能到达椎体间融合的效果。 In traditional intervertebral implant patient autogenous bone may cause complications in patients disadvantages bone graft area and the like, the prior art metal implants or other artificial materials present poor biocompatibility, can not form new bone implant material or osteogenic potential difference among not reach the spinal fusion effect. 用同种异体骨松质骨块力学强度差可至塌陷,且未设计成符合解剖结构的形状,不能预期达到恢复生理弯曲、不能防止植入物脱位。 With the mechanical strength of cancellous bone to bone allograft difference may collapse, and not designed to conform to the shape of the anatomy, can not be expected to achieve recovery physiological curvature, can not prevent the dislocation of the implant. 将小管状骨加工成外螺纹圆柱体Cage,其皮质骨单薄,植入时有爆裂。 Small tubular bones processed into an externally threaded cylinder Cage, which thin cortical bone, have burst when implanted. Cage植入前工具攻丝对椎体终板的破坏,使Cage对颈椎体松质骨的挤压骨折、塌陷。 Cage tapping tool prior to implantation damage to the vertebral end plates, so that compression of the cervical Cage cancellous bone fracture, collapse. 另Cage植入后其中央空腔结构(管状骨腔)与人体的纵轴垂直,而Cage皮质骨厚度有限,使之在爬行替代过程中Cage出现崩裂、塌陷,这些均易导致椎间隙塌陷狭窄、神经受压。 Another Cage structures after implantation, which central cavity (lumen bone) and the longitudinal axis of the body, and a finite thickness Cage cortical bone, so that the creeping substitution process Cage chipping occurs, collapse, which are easily lead to collapse of the disc space narrowing , nerve compression. Cage没有设计成符合颈椎生理弯曲的形状,加之Cage切入椎体,导致部分别人出现颈椎成角畸形。 Cage is not designed to conform to the curved shape of cervical, coupled with Cage cut into the vertebral body, resulting in some people appear cervical angular deformity. 所以临床基本停用。 So basic clinical disabled.

[0003] 理想的颈椎间隙融合植骨材料应该具备四个方面的特征:其一力学强度好,可支撑植入部位相应的重量、保持椎间隙的高度空间;其二成骨能力好,可生长新骨使椎间隙发生骨性愈合达到融合的目的;其三生物相容性好,不产生不良刺激、排异等导致严重并发症使手术失败;其四外形结构符合颈椎间隙解剖结构,有配套工具能使手术更加可行、安全、便捷。 [0003] over the cervical vertebra bone fusion material should have four characteristics: One good mechanical strength, may support the corresponding weight of the implantation site, to maintain the intervertebral space height; Good Second osteogenesis, may be grown the occurrence of new bone intervertebral bone healing achieve integration; Third good biocompatibility, no adverse stimulus, resulting in rejection and other serious complications of the surgery fails; Fourth shape structure conforms to the anatomy of the cervical spine clearance, and is supported tools can make surgery more feasible, safe, and convenient. `发明内容 `SUMMARY
