Abstract
A surgery device assembly for minimally invasive spinal surgery is provided. The surgery device assembly includes a plurality of pedicle screws, a least one parallel bridge, a guiding device and an elongated rod. The plurality of pedicle screws are drilled into the corresponding spine respectively. Each pedicle screw is clamped by the corresponding parallel bridge in order to keep the cannulas parallel to each other. The top of the sidewalls is a U-type trough in order to adjust a direction of each pedicle screw to the same way. The proper shape of the elongated rod is bent according to the curve formed with the U-type grooves of pedicle screws. The elongated rod is seated in trough portion of each pedicle screw by puncturing the guiding device. The elongated rod is then secured by nuts in order to fix a bony structure.
