摘要：
The useful model refers to the medical technique used in traumatology, neurosurgery, vertebrology. The device is two coaxially spaced elongated hollow metal tubes - internal and external. On the side of the proximal end of the inner tube, a millimeter scale is placed on its outer side surface to assess the degree of mutual movement of the tubes and a manipulation handle is placed, and its distal end is cut at an angle of 25-30º with the aperture open to the side coinciding with the direction of the manipulation handle. From the proximal end of the outer tube on its lateral surface is a collet chuck ensuring mutual fixation of the position of the tubes relative to each other. The length of the inner tube exceeds the length of the outer tube by 30 mm. The external diameter of the outer tube does not exceed 10 mm. The internal diameter of the inner tube is proportional to the outer diameter of the endoscope for its free movement inside the device. The useful model makes it possible to perform the most safe and atraumatic surgical access in a shorter time due to ensuring optimal visualization of the posterior backbone structures in a continuous mode and expanding the functionality of performing various manipulations on the neural structures of the spinal canal. 1 pr., 7 ill.
