Guide landmark FOR CARRYING pedicle screws osteosynthesis SPINE

摘要

The utility model relates to medicine, namely to the devices for optimization of transpedicular vertebral locking and can be used in traumatology in treatment of injuries and diseases of the spine. Guide represented interconnected protractor 1 three metal plates, one of which - the core diameter 2 of 5 mm, ending in a split sagittal plane 7 and the other two - tubes 3, 4 with a diameter of 15 mm. To the rod 2 is fixedly attached protractor and to the tubes 3 and 4 - with the screws 5 and 6, which tube can be fixed in position at any angle and at the desired distance from the shaft 2. On the side surface of the workpiece 7 - bifurcated end of the rod 2 8 has a hole diameter of 2 mm, intended for fixing the entire device to the spinous process of the vertebral Kirschner wires. The liner pipe is introduced, allowing to reduce the rod diameter from 15 mm to 5 mm. After the liner is held awl 3-5 mm in diameter which forms a channel for conducting subsequent threaded transpedicular screw. After closure channelization awl liner is removed and the tube is held screwdriver fixed therein threaded pedicle screw. The technical result - conducting pedicle screws immediately to both legs vertebra with preforming channel awl screw and screwdriver, followed by a fixed screw screwed therein, which considerably reduces the duration and operational reception quality improves operational reception. 3 Fig.
