    • A system for stabilization of the spinal column, including an elongate support member extending along an axis and a plurality of anchor members configured for anchoring to respective vertebrae. A first of the anchor members is engaged to the support member in a manner that substantially prevents axial movement of the support member relative to the first anchor member, and a second of the anchor members is engaged to the support member in a manner that allows substantially unconstrained axial movement of the support member relative to the second anchor member. In a further embodiment, a third of the anchor members is engaged to the support member in a manner that also allows substantially unconstrained axial movement of the support member relative to the third anchor member, with the second and third anchor members positioned on opposite sides of the first anchor member.
    • 一种用于稳定脊柱的系统,包括沿着轴线延伸的细长支撑构件和被配置用于锚固到相应椎骨的多个锚定构件。 锚固构件中的第一个以基本上防止支撑构件相对于第一锚固构件的轴向移动的方式接合到支撑构件,并且锚定构件中的第二锚定构件以允许基本上 支撑构件相对于第二锚定构件的无约束轴向运动。 在又一个实施例中,三个锚固构件以支承构件相对于第三锚定构件基本上无约束的轴向移动的方式接合到支撑构件,其中第二和第三锚定构件位于 第一个锚定成员。

    • A minimally invasive reaming assembly for creating an entry portal into the canal of a bone and for providing a working channel in which to ream the canal of a bone. The assembly includes a sleeve, a housing and an inner reamer. The sleeve is an elongated cylindrically-shaped hollow sleeve that has a proximal and a distal end, with the distal end having a plurality of cutting blades. The housing is attached to the sleeve and is generally cylindrical in shape and it has a top portion, a bottom portion and a through bore. The top portion includes a releaseable locking mechanism for engaging the inner reamer within the housing. The inner reamer has an elongated cannulated body and proximal and distal ends. The distal end has a rotatable reaming head and the proximal end has a drill shaft and a connector for connection to a drill. A portion of the body includes an annular collar with a tab for engaging a notch in the housing. The reamer is sized and shaped for insertion through the bore of the housing and the sleeve. The reaming assembly is configured to create an entry portal into the canal of a bone and to provide a working channel in which a plurality of reamers of graduated sizes are inserted for progressively reaming the canal of a bone.
    • 一种微创扩孔组件,用于创建进入骨的运河的进入门,并提供一个工作通道,在该工作通道中,用于使骨的运河受到刺激。 组件包括套筒,壳体和内铰刀。 套筒是细长的圆柱形中空套管,其具有近端和远端,远端具有多个切割刀片。 壳体附接到套筒并且通常为圆柱形,并且其具有顶部,底部和通孔。 顶部包括用于与内部铰刀在壳体内接合的可松开的锁定机构。 内铰刀具有细长的插管体和近端和远端。 远端具有可旋转的铰接头,近端具有钻轴和用于连接钻头的连接器。 主体的一部分包括具有用于接合壳体中的凹口的凸片的环形凸缘。 铰刀的尺寸和形状用于插入通过壳体和套筒的孔。 扩孔组件被配置为创建进入骨的运河的入口,并提供工作通道,其中插入多个刻度尺寸的铰刀用于逐渐扩孔的运河。
