    • A rod reduction instrument for position a rod relative to a seat of a bone anchor in a spinal implant system is provided. The instrument includes three concentric cannulas with circumferentially aligned rod receiving portions formed therein. One cannula is movable with respect to another to lock and unlock the seat of a bone anchor to the rod reduction instrument. The rod to be reduced is positioned inside at least one of the rod receiving portion. One cannula is moved with respect to another to lock the seat of the bone anchor to the rod reduction instrument. Once locked to the bone anchor, the remaining cannula is moved to reduce the distance between the rod and the seat within at least one of the rod receiving portions. The distance between the rod and the seat is reduced until the rod is position inside the seat. A secondary instrument is inserted through a central bore of the rod reduction instrument to introduce a cap and lock the cap to the seat securing the rod to the bone anchor.
    • 提供了一种用于在脊柱植入系统中相对于骨锚的座位定位杆的杆减小器械。 该仪器包括三个同心插管,其中形成有圆周对准的杆接收部分。 一个套管可相对于另一套管移动,以将骨锚固件的座椅锁定并解锁到杆减速器械。 要还原的杆位于杆接收部分中的至少一个中。 一个套管相对于另一个套管移动,以将骨锚固件的座椅锁定到杆减速器械上。 一旦锁定到骨锚固件上,剩余的套管被移动以减小杆和座内至少一个杆接收部分之间的距离。 杆和座椅之间的距离减小,直到杆位于座椅内部。 辅助器械通过杆减速器的中心孔插入以引入盖并将帽锁定到将杆固定到骨锚上的座椅上。

    • A dynamic rod implantable into a patient and connectable between two vertebral anchors in adjacent vertebral bodies is provided. The dynamic rod fixes the adjacent vertebral bodies together in a dynamic fashion providing immediate postoperative stability and support of the spine. The dynamic rod comprises a first rod portion dynamically connected to a second rod portion at a retainer that has separate chambers for receiving rod portions. One rod portion is configured for longitudinal movement and the other rod portion is configured for polyaxial angulation relative to the retainer. The dynamic rod is configured such that the retainer is located proximate to one of the facet joints when implanted into a patient. The dynamic rod permits relative movement of the first and second rod portions allowing the rod to carry some of the natural flexion, extension and rotation moments of the spine.
    • 提供了植入患者体内并可在相邻椎体内的两个椎骨锚固件之间连接的动态杆。 动态杆将相邻的椎体以动态方式固定在一起,提供立即的术后稳定性和支撑脊柱。 动态杆包括在保持器处动态地连接到第二杆部分的第一杆部分,其具有用于接收杆部分的单独的室。 一个杆部分构造成用于纵向移动,另一个杆部分构造成相对于保持器进行多轴成角度。 动态杆被构造成使得当植入患者时保持器位于小面关节之一附近。 动态杆允许第一和第二杆部分的相对运动,允许杆承载脊柱的一些自然弯曲,伸展和旋转力矩。
