发明名称 Pedicle screws and dynamic adaptors
摘要 The present invention may include a pedicle screw with a multifunctional adaptor, a strain reliever, and a dual-surface cap. The multifunctional adaptor may include a convex pivot ring for improving multi-axial movement and locking stability, an integrated locking mechanism for improving maneuverability, and an integrated compression member for improving the assembly process. The strain reliever may be formed along a neck of the pedicle screw for relieving mechanical stress asserted thereto, and thereby preventing a breakage thereof. The dual-surface cap may provide a slightly sloped surface for reducing the tension of the stabilizing rod. The present invention may also provide for a dynamic adaptor for flexibly connecting two stabilizing rods, which may be versatilely adapted to various pedicle screw configurations.
