A spinal filler comprises: an upper pad having a top surface to which a skidding-resistant structure is provided and at least one bone graft cavity is formed and having a bottom surface to which at least one fitting bar is mounted, the fitting bar having a lower end bar diameter greater than an upper end bar diameter a lower pad, which has a bottom surface forming a skidding-resistant structure and at least one bone graft cavity and has a top surface to which at least one fitting bar is mounted, the fitting bar having a lower end bar diameter greater than an upper end bar diameter and an elastic body arranged between the upper and the lower pads. The elastic body tightly encompasses the fitting bar on the bottom surface of the upper pad and the fitting bar on the top surface of the lower pad so that the upper and lower pad are bound together. The spinal filler features elastic cushioning, which provides the intervertebral discs in a treated portion with natural mobility and a range of movement to thereby maintain the original function of the vertebral joints and avoid damaging the upper and lower spinal joints, allowing the upper and lower pads of the spinal filler to integrate with the upper and lower vertebras after having been installed for a while in order to enhance stability of installation.一種脊椎填充塊,包含:一上墊體,在墊體頂表面設有止滑構造,以及設有至少一植骨凹坑,並在墊體底面至少凸設一嵌接柱,並令該嵌接柱下端柱體外徑大於上端柱體外徑;一下墊體,在墊體底表面設有止滑構造,以及設有至少一植骨凹坑,並在墊體頂面至少凸設一嵌接柱,並令該嵌接柱下端柱體外徑大於上端柱體外徑;以及一彈性體,係被設置於上墊體與下墊體之間;藉該彈性體可將上墊體底面的嵌接柱及下墊體頂面的嵌接柱緊密包覆,使之與上、下墊體結合(bind)成一體;利用該脊椎填充塊具備的彈性緩衝特性以提供治療部位的椎間盤自然的活動能力與運動範圍,以維持上下椎骨間原有關節所提供的效能,避免損害上下節脊椎關節,更可於安裝一段時日後,該脊椎填充塊的上下墊體可即分別與上下脊椎骨固結成一體,增益安裝穩固性。上墊體...1尖錐齒...12a植骨凹坑...13環槽部...13a嵌接柱...14環圈部...14a下墊體...2尖錐齒...22a植骨凹坑...23環槽部...23a嵌接柱...24環圈部...24a彈性體...3
