    • A flexible spinal fixation rod assembly that provides relatively stiff bending compliance provided by a core rod or tube that is connected to surrounding spring and associated couplings in such a way that when the core rod is bent, the spring extends and the associated couplings move away from each other, with the core rod generating a force tending to return the core rod to its unbent configuration thereof and the spring generating a force tending to return the couplings to there unextended configuration thereof. Couplings connect each end of the rod or tube to corresponding pedicle screws for attachment to corresponding vertebrae. As the spine bends, this arrangement allows the spine to bend against limited resistance, exhibiting the necessary axial and compressive strength, and applies force to return the spine to its original configuration.
    • 柔性脊柱固定杆组件,其提供由芯棒或管提供的相对刚性的弯曲顺应性,所述芯棒或管连接到周围弹簧和相关联的联接器,使得当芯棒弯曲时,弹簧延伸并且相关联的联接件远离 彼此之间,芯棒产生趋向于将芯棒返回到其未弯曲构型的力,并且弹簧产生趋向于将联接件返回到其未延伸构造的力。 联轴器将杆或管的每个端部连接到相应的椎弓根螺钉,以连接到相应的椎骨。 当脊柱弯曲时,这种布置允许脊柱受到限制的阻力弯曲,呈现必要的轴向和抗压强度,并施加力使脊柱返回其初始构型。

    • A tool for delivering bio-compatible solid, fluid or mixed solid and fluid substances to an operating site within a patient. The tool has a tubular body or barrel with a central longitudinal through hole and a flow control valve for selectively allowing material to flow from a holding chamber within the barrel through an extender tip to a dispensing end of the tool. A plunger having a piston at one end may be inserted through the dispensing end of the barrel and drawn distally to aspirate material into the holding chamber using a syringe attached to the proximal end of the barrel, after which the valve is closed to retain the material in the chamber. The plunger, which fits into the through hole from either end of the barrel, is then removed and re-inserted into the proximal end of the barrel, the barrel valve is opened, and the plunger is pushed to move the material in the holding chamber through the extender tip and out the distal end of the barrel. An optional rod and multi-pronged blade mixing assembly may be inserted into the proximal end of the barrel to mix stored material after it is aspirated into the holding chamber and before it is dispensed.
    • 用于将生物相容的固体,流体或混合固体和流体物质输送到患者体内的操作部位的工具。 该工具具有带有中心纵向通孔的管状主体或筒体,以及流量控制阀,用于选择性地允许材料从筒体内的保持室通过扩张器尖端流到工具的分配端。 具有在一端具有活塞的柱塞可以插入通过筒的分配端并向远侧方向拉伸,以使用连接到筒的近端的注射器将材料吸入保持室中,之后关闭阀门以保持材料 在房间里 然后从柱塞的任一端装配到通孔中的柱塞被移除并重新插入到筒的近端中,筒形阀被打开,柱塞被推动以移动保持室中的材料 通过扩展器尖端并且从筒的远端出来。 可选的杆和多管叶片混合组件可以插入到筒的近端中,以将储存的材料吸入储存室中并在分配之前混合储存的材料。
