    摘要: The present invention relates to a locking mechanism and method of locking the relative positions of a fixation device like a bone screw and of a stabilization device like a rod. The locking mechanism includes a seat, a washer and a cap. The seat includes a bottom portion configured to receive the fixation device such that a socket of the bottom portion engages part of the fixation device and prevents the fixation device from passing entirely therethrough. The seat further includes a side portion configured to receive the stabilization device, a washer and a cap. When the washer and cap are fully engaged with the seat, the fixation device may be locked independent of the stabilization device. The locking mechanism may also include a locking element for locking the stabilization device.
