摘要： A flexible shaft assembly for transmitting rotary motion between spaced components that are mounted on articulated members. The flexible shaft, which has a significant bending flexibility, comprises a proximal section connected to a driver device, a distal section connected to a driven component, and an intermediate section. The proximal and distal sections, which are free to bend, rotate about curved axes. One or more rigid sleeves coaxially mount on the intermediate section for reducing torsional deflections of the shaft as it rotates.

摘要： 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.
摘要翻译：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。
