    • A spinal implant has a mechanism for inhibiting a bone screw used in attaching the spinal implant to the spine from backing out from the spinal implant once the bone screw has been received in the spinal implant. The spinal implant has a bone screw bore defining a bore wall in which is disposed a resilient closed curve band or ring. The resilient closed curve band has a plurality of resilient segments that extend into the bore. Each one of the plurality of resilient segments form a spring that allows a head of a bone screw to ingress there through but prevents the head of the bone screw from egress there from. The resilient closed curve band forms a retention ring that is received in one or more slots, channels, grooves or the like in the bore hole wall. The plurality of resilient segments are formed as arcs, curves and/or configured arcs/curves that extend radially inward from outer arced or curved portions of the retention ring.
    • 一旦骨螺钉已被接收在脊柱植入物中,脊柱植入物具有用于抑制用于将脊柱植入物附接到脊柱的骨螺钉从脊柱植入物退出的机构。 脊柱植入物具有限定孔壁的骨螺钉孔,其中设置有弹性闭合曲线带或环。 弹性闭合曲线带具有延伸到孔中的多个弹性段。 多个弹性段中的每一个形成弹簧,该弹簧允许骨螺钉的头部进入其中,但是防止骨螺钉的头部从那里流出。 弹性闭合曲线带形成保持环,其被容纳在钻孔壁中的一个或多个槽,通道,凹槽等中。 多个弹性段形成为从保持环的外弧形或弯曲部分径向向内延伸的弧,曲线和/或构造的弧/曲线。

    • A spinal rod connector assembly for use with a vertebral bone screw has an articulating clamp for 1) fixing an orientation of the spinal rod connector assembly relative to and on the vertebral bone screw, and 2) attaching a separate spinal rod onto the spinal rod connector assembly in concert with one another. The articulating clamp resides in a body of the spinal rod connector assembly and transfers a received downward force laterally to a spinal rod component of the spinal rod connector assembly which is configured to abut the spinal rod and hold the spinal rod between itself and a spinal rod holder of the spinal rod connector assembly. The articulating clamp thus improves the force transfer efficacy of the system.
    • 与脊椎骨螺钉一起使用的脊椎杆连接器组件具有铰接夹具,用于1)相对于椎骨螺钉固定脊柱杆连接器组件的取向,以及2)将单独的脊柱杆附接到脊柱杆连接器 组合相互协调。 所述关节式夹具位于所述脊柱杆连接器组件的主体中,并将​​所接收的向下的力横向地传递到所述脊柱杆连接器组件的脊柱杆部件,所述脊柱杆连接器组件被构造成邻接所述脊柱杆并将所述脊柱杆保持在其与脊柱杆 脊柱杆连接器组件的支架。 因此,铰接夹具改善了系统的力传递效能。
