    • A compression and distraction shaft assembly applies compression and distraction to bones including vertebrae. Shaft A assembly and shaft B assembly are attached together via a polyaxial fulcrum. The polyaxial fulcrum allows all rotational degrees of freedom between shaft A assembly and shaft B assembly. Such fulcrum, during compression and distraction, does not impart ancillary stresses or motion to vertebrae. An hourglass-shaped bore for engaging pliers is formed in approximately middle of both the shaft A assembly and the shaft B assembly. Distraction pliers having cylindrical tips are used to apply distraction to vertebrae. Once handles are pressed to impart an appropriate amount of distraction to the vertebrae, they are locked in this position. Compression pliers having cylindrical tips are used to apply compression to vertebrae. Once handles are pressed to impart an appropriate amount of compression to the vertebrae, they are locked in this position.
    • 压缩和牵引轴组件对包括椎骨的骨头施加压缩和分心。 轴组件和轴B组件通过多轴支点连接在一起。 多轴支点允许轴A组件和轴B组件之间的所有旋转自由度。 在压缩和牵引期间,这种支点不会对椎骨施加辅助应力或运动。 用于接合钳子的沙漏形孔形成在轴A组件和轴B组件的大致中间。 使用具有圆柱形尖端的牵引钳将牵引力应用于椎骨。 一旦手柄被按压以向椎骨施加适当数量的分心,它们被锁定在该位置。 使用具有圆柱形尖端的压紧钳将压缩应用于椎骨。 一旦手柄被按压以向椎骨施加适当的压缩量,则它们被锁定在该位置。

    • Pedicle screws are designed to provide polyaxial coupling to pedicles of a vertebra. Intermediate pieces are attached to the pedicles screws and receive extender shafts. Extenders are inserted in the intermediate piece. The extenders project the anatomic points located in the cage outside the patient's body to facilitate proper contouring of a rod. An alignment linkage is used to ensure that the extenders are parallel to each other. The alignment linkage includes a linkage frame, an articulating linkage and a locking member. The articulating linkage has all rotational degrees of freedom and thereby adapts to any varying trajectories of the extenders and distance between the extenders. The alignment linkage includes a locking member with a pop-up indicator. The pop-up indicator notifies the users when the locking member is tightened with two of the extenders in non-parallel configuration.
    • 椎弓根螺钉设计用于提供椎骨椎弓根的多轴联接。 中间件连接到椎弓根螺钉上并接收延长轴。 扩展器插入中间件。 延伸器将位于病人身体外部的笼子中的解剖点投射到杆上,以便适当地进行轮廓。 使用对齐连杆来确保延伸器彼此平行。 对齐连杆包括连杆机构,铰接连杆机构和锁定部件。 铰接连杆具有所有旋转自由度,从而适应延伸器的任何变化的轨迹和延伸器之间的距离。 对齐连杆包括具有弹出指示器的锁定构件。 当两个扩展器处于非并联配置时,弹出的指示器会向用户通知锁定构件是否拧紧。
