摘要

1. A device for introducing screws for transpedicular fixation of vertebrae, characterized in that the hollow tube for sewing at a predetermined angle and a pointed rod with a support pad intended for the design direction, interconnected by a hinge and a protractor, and a protractor secured with screws that It may be fixed at a predetermined position. ! 2. A method for introducing screws transpedicular fixation of vertebrae, comprising determining the direction of introduction and the point of the screw, the preparation introduction zone, characterized in that on the conveying device according to claim 1 exhibit vertebral arch amount of tilt angle and tighten the screw, the tip of the rod is mounted on the vertebral spinous process into which the screw through the support structure orients the pad, through the hollow stem awl performed for the channel in a bone, the end of the screw is introduced into the channel and is introduced into a vertebra.
