Abstract
中空椎弓根螺钉为适用胸腰椎骨折、滑脱,胸腰
椎肿瘤后路手术的一种新颖螺钉,改进手术中定标钻
孔原先后二次用克氏钉打入、拔出,为仅一次用克氏
钉打入,而后用新颖螺钉套入克氏钉与万向关节和钢
棒共同完成关节固定,简化操作,手术中调整容易,不
易伤神经,便于推广使用。可替成迪克(Dick)或斯
蒂夫(Steffce)的椎弓根螺钉。
Description
本实用新型涉及的是一种适用胸腰椎骨疾后路手术的内固定器械,属于骨科医疗器械技术改进。
目前胸腰椎骨折、滑脱,胸腰椎肿瘤的后路手术用内固定器械均采用迪克〈Dick〉或斯蒂夫〈Steffee〉式,由万向关节,钢板或钢棒,椎弓根螺钉组成。上述骨疾后路手术中椎弓根的定位标志,选定椎弓根钻孔点是手术的关键。应用迪克〈Dick〉或斯蒂夫〈Steffee〉式内固定器装置进行手术时,共同特点是先用克氏钉钻孔,深至约30mm,后拔出,再入克氏钉穿出椎弓根外,拔出,先后两次,用不同直径克氏钉进行钻孔定位。置入椎弓根螺钉,而后用万向关节,钢板或钢棒,达到固定节段目的。手术操作用X线电视观察。存在问题是:易损伤神经根,可能造成患者致残。又手述时间长,费时又费力,且不容易调整。因而基层如地区及县级医院无法开展此类骨科手术,较难以推广。
鉴于现有技术中存在不足,为此进行技术改进是必要的。
本实用新型目的是为手术提供一种使操作简便,容易调整,便于推广的椎弓根螺钉。
本实用新型要点是椎弓根螺钉为中空式,它能套入克氏钉。
应用本实用新型中空椎弓根螺钉,与万向关节,钢棒组成的内固定器装置进行前述骨疾后路手术时,先用1.0mm的克氏钉打入钻孔定位,中空椎弓根螺钉套入已定位的克氏钉旋置,而后用万向关节和钢棒,固定关节段,拔出克氏钉。
附图1:内固定器装置
附图2:中空椎弓根螺钉
以胸腰椎滑脱手术为例:在滑脱椎两侧上、下各二个邻椎用1.0mm克氏钉插入钻孔定位,见〈附图1〉〈附图2〉,套入中空椎弓根螺钉〔1〕,将螺钉〔1〕旋入,使前段松质骨螺钉均进入椎弓根,见〈附图2〉而后用万向关节〔2〕和钢棒〔3〕完成固定关节段,拔出克氏钉。
应用本实用新型中空椎弓根螺钉优点是:手术操作简单化,仅用一次克氏钉插入钻孔定位,且因椎弓根螺钉为中空式,则是直接套入克氏钉置入椎骨,不容易损伤神经根,容易调整方向。手术操作简易后,适用在广大基层地区医院开展手术,有较大推广价值。
椎弓根螺钉为中空式,必要时注入骨水泥于螺钉内空,则可增强螺钉抗拉强度,也增加适用性。
中空椎弓根螺钉可替代迪克〈Dick〉式或斯蒂夫〈Steffee〉式的椎弓根螺钉。
