A useful model refers to medicine, namely traumatology, orthopedics and vertebrology. The impactor is made of stainless steel in the form of two tubes. The inner tube, 260.5 mm long, has an outer diameter of 8.0 mm and an inner diameter of 6.0 mm. In the middle of the tube there is an external thread. At one end of the inner tube is inserted a nut with a diameter of 17.0 mm and a width of 10.0 mm. On the other side, the inner tube has a longitudinal length of 42.5 mm, then the tube extends to 10.0 mm over the last 20.0 mm and ends with two extensions up to a diameter of 12 mm. At the enlarged ends of the tube there are two flat hooks, located at a distance of 7.0 mm from each other, the width of the hooks at the base of 6.0 mm, in the free part of 4.0 mm, the length of 6.5 mm, the thickness of 1.5 mm. The outer tube is 145.0 mm long and has an internal diameter of 10.0 mm. In the middle part of the outer tube there is an internal thread. At one end of the tube there is a pressed nut with a diameter of 14.0 mm and a length of 22.0 mm. The outer tube, when assembled, is inserted into the inner tube. To install hooks into the device, rotate the outer tube clockwise, and after installation - rotate the outer tube counter-clockwise. Hooks thus enter the device as an anchor. The final stabilization of the impactor and the device occurs when the screwdriver is installed in the slot of the screw of the device. The screwdriver is a steel cylinder with a length of 306.0 mm and a diameter of 6.0 mm with a square spline at one end with a diameter of 2.0 mm, at the other end a nut with an outer diameter of 10.0 mm is pressed. When the nut with the screwdriver rotates clockwise, the extension device extends. At one end of the tube there is a pressed nut with a diameter of 14.0 mm and a length of 22.0 mm. The outer tube, when assembled, is inserted into the inner tube. To install hooks into the device, rotate the outer tube clockwise, and after installation - rotate the outer tube
