| Abstract: | A position device which can be modulated at the three dimensions for cervical pedicle for screw placement is introduced.Screws could be inserted in cervical pedicles individually with the device being used as drilling jig during operation.Not only provides the principle of design and method of use,but also deduces the relationship between the measurements of preoperative pictures and the angles of drilling ringers of the position device,and also compiles applied software for numeration.The function is estimated and the errors is analysed. |
