Description

 The invention relates to medicine, namely to traumatology and orthopedics.

 A device for stretching the spine, containing the pelvic support, on which the spring-loaded screw distractor is installed with the possibility of rotation in two planes, at the end of which there is a correction element [1], adopted on the analogue.

 A device for traction, containing a frame with vertical uprights, traction, cable with a system of blocks [2], adopted as a prototype.

 The aim of the invention is to expand the range of correction of deformations of the lumbosacral spine.

 The goal is achieved in that the belt is installed with the possibility of free fall to a given height.

 In FIG. 1 is a front view of a parachute projectile; in FIG. 2 - side view; in FIG. 3 - groove; in FIG. 4 is a section BB in FIG. 3.

 The parachute shell consists of a frame 1 with vertical struts 2. In the center of the frame 1 there is a spindle 3, which rotates with an electric motor 4 through a gearbox 5.

 When the lead screw 3 is installed rod 6, which has the ability to move along the axis of the screw 3. Rod 6 abuts against the nut 7 and connects to the cable 8, thrown through a system of blocks 9.

 The other end of the cable 8 is connected to the chutes 10, to which the belt 12 is fastened with carabiners 11. A latch 13 is mounted on the rack 2, which can be moved along the axis of the rack 2, and is fixed in position by the clip 14. On the latch 13 is a dog 15, which rotates around the axis 16 with the angular movement of the lever 17. The dog 15 enters the groove 18 located in the thrust housing 6.

 Next to the stand, a control panel 19 is mounted on the wall, which has the Up, Down buttons.

 Before treatment, the doctor (methodologist) puts a belt 12 on the patient’s chest. Then, with the help of carabiners 11, the belt 12 is fastened to the cups 10.

 After that, the doctor presses the Up button on the control panel 19. In this case, the electric motor 4 is turned on, which rotates the spindle 3 through the gearbox 5, as a result of which the nut 7 is lowered, moving the rod down.

 Rod 6 pulls the cable 8, thrown over the system of blocks 9 and connected with the help of rods 10 and carabiners 11 with a belt 12. As a result, the patient rises. After the patient is raised to a height of 500 mm, the "Up" button is released and the lifting stops. The doctor moves the latch 13 along the axis of the rack 2 until the dog 15 comes into the groove 18 of the rod 6. In this position, the latch 13 is fixed by a clip 14.

 Then the doctor presses the Down button on the control panel 19 and holds it for a while, until the nut 7 moves away from the rod 6 by the amount of discharge. After the patient has relaxed the muscles of the lumbar region, the doctor presses the lever 17, which leads the dog 15 out of the groove 18, and the rod 6, under the influence of the patient’s weight, moves up to the stop with the nut 7. In this case, the patient falls down by the amount of discharge and then stops abruptly. The resulting dynamic forces eliminate the rotational and axial displacements of the vertebrae of the lumbar spine. If necessary, the procedure is repeated.

 When lowering the patient to its original position, it is necessary to bring the dog 15 out of the groove 18 and press the "Down" button on the control panel 19. The button must be held until the patient is completely lowered. When the patient is on the floor, it is necessary to unfasten the carabiners 11 and remove the belt 12.

 The parachute shell is implemented as follows: the patient at the level of the lower thoracic spine with D7-D12 is secured with a belt 12, and when tightening, a force cone should be created, i.e. the lower section is stronger than the upper. The patient is pulled up, resulting in traction of the lumbosacral spine.

 After 5-7 minutes of stretching, the patient is lowered to the stop and the stop is adjusted to determine the necessary distance the patient is in a state of free fall in cm (from 3 to 10 cm) to its rigid fixation at the lower level. In the patient’s position in the hanging, there is an increase in intervertebral distances, disc depression, elimination of compression of the roots of the spinal cord.

 With a sudden stop of the patient’s body after discharge, additional increases in intervertebral distances occur. The amount of discharge is determined by the doctor individually for each patient, taking into account weight, age, pathology of the spine, disc protrusion, the presence of radicular syndrome. Contraindications are spina bifila, osteoporosis, the presence of oncological pathology with metastases in the bone structure.
