| Abstract: | In view of the difficulties of the cervical pedicle for screw placement, based on the theory of screw thread micrometer and reaming hole thread hinged pair, not only designs and produces the aiming device for individual screw placement, but also deduces the relationship between the measurements of pre-operative pictures and the angles of drilling ringers of aiming device, and also compiles applied software for numeration. The study provides a dependable approach to advance the accuracy rate during operation of the cervical pedicle for screw placement deeply. |
