Navigation device for screw insertion during transpedicular fixation on the thoracic and lumbar spine

摘要

The utility model relates to medicine, namely to traumatology, and is intended for use in the installation of fixing transpedicular screws on the thoracic and lumbar regions in case of injuries and diseases of the spine.;The navigation device contains a guide in the form of two vertical bars with spacers along the edges, in which movable sliders are installed, which can change the distance from the center of the device and rotate around the axis. The device is equipped with a U-shaped base with a ruler for moving along the vertebral arches with the possibility of fixing with rods at the base of the spinous vertebrae. The base is rigidly connected to additional vertical bars, which end with a handle for easy positioning relative to the axis of the vertebra. To change the inclination in the sagittal plane, the base and the guide are connected by a movable axis at the bottom of the bars and an adjusting screw at the top of the bars.;The navigation device ensures the accuracy of screw insertion and reduces the operation time. 10 ill.
