Three-dimensional guide instrument of the insertion hole produced wire for pedicle screw

摘要

In carrying piercing the pedicle screw to the correct positions SOLVED] anatomy, and three-dimensional guide device of the wire to be used to make an insertion hole for inserting the pedicle screw, the production method I is an object of the present invention to provide. A three-dimensional guide device for pedicle screw for insertion hole fabricated wire which is produced based on the CT image taken SOLUTION: A spinal three-dimensional guide instrument, planar bone form surface of the insertion site position and has a contact surface that contacts the abutment to, and a guide block portion extending perpendicularly from the abutting surface, the guide block portion is characterized by having a guide hole for restricting the insertion direction of the insertion hole made wire .
