摘要： Instruments are provided for shifting elongate members, such as spinal rods, with respect to coupling members of spinal fixation systems. The instruments include a low friction drive mechanism having one or more rolling elements that ride along a helical groove or track in order to transform rotational movement of a drive member into linear shifting of a reducer member that shifts the elongate member. A one-way locking mechanism may be provided to selectively prevent unwanted counter-rotation of the low friction drive mechanism. The one-way locking mechanism may include annular ratchet teeth arranged on the exterior of the drive member and a ratchet pawl located adjacent to the teeth and selectively engageable therewith.

摘要： A minimally invasive and open surgery surgical system for implanting spinal screw assemblies to be connected by a spinal rod is disclosed. In one form, the system includes an improved tool device for inserting a cap insert into an initial and final locking of a screw assembly and securing a spinal rod inserted through an incision to a vertebra. In another form, the system also includes a screw fixation system that allows greater variability in thread diameter for orthopedic implant for in the spine, iliac crest, or bones.
摘要翻译： 公开了一种用于植入由脊柱杆连接的脊椎螺钉组件的微创和开放手术外科系统。 在一种形式中，该系统包括改进的工具装置，用于将帽插入件插入到螺钉组件的初始和最终锁定中并将通过切口插入的脊柱杆固定到椎骨。 在另一种形式中，系统还包括螺钉固定系统，其允许在脊柱，髂嵴或骨骼中矫形植入物的螺纹直径更大的变化。

摘要翻译： 提供了用于相对于脊柱固定系统的联接构件移动细长构件（例如脊椎杆）的仪器。 这些仪器包括具有一个或多个滚动元件的低摩擦驱动机构，所述滚动元件沿着螺旋槽或轨道行进，以便将驱动构件的旋转运动变换成使细长构件移动的减速器构件的线性移动。 可以提供单向锁定机构以选择性地防止低摩擦驱动机构的不希望的反向旋转。 单向锁定机构可以包括布置在驱动构件的外部上的环形棘轮齿和邻近牙齿定位并可与其啮合的棘爪。
