Description

The present invention relates to the field of medical technology and can be used in the treatment of the spine, namely lumbalgia, discogenic radiculitis and spondylolisthesis to eliminate compression of the spinal disc during protrusion, hernia, etc.

A device is known for repositioning hernias of disks, vertebrae, containing a base with a fixed platform, provided with guides on which a movable platform is connected, which is hinged to the pelvic section, a loading mechanism with a flexible traction and a dynamometer, as well as patient fixation elements located on a fixed platform and pelvic sections. The hinge is installed at the proximal end of the pelvic section on its longitudinal axis of symmetry and is made with three degrees of mobility [1].

However, the known device has the disadvantages of:

- the entire lumbar spine is subjected to stretching;

- reduction is achieved by additional manipulations, for example, pressing through soft tissue to the projection point of the fallen core of the spinal disc;

- manipulations are performed in the unbent position of the spine, which creates a risk of pinching.

A device for stretching the spine, containing a base, a bed with chest fixators, a pelvic girdle connected by flexible rods with a vibrator and a loading unit in the form of a bracket fixed to the base with a block, cable and load [2].

However, when using the known device, the entire spine, fixed by the thoracic and pelvic retainer, undergoes straightened lordosis. In this case, the force exerted during traction acts on the entire spine equally in all planes.

Closest to the proposed is a table for manual therapy of the lumbar spine, containing support for the torso of the patient, a movable part connected to one of the ends of the support. A footrest for the patient is attached to the lower end of the movable part, the position of which is changed using the handle. The femur of the limbs and the chest of the patient’s torso are fixed with straps to the table. Using a special mechanism, the movable part of the table moves smoothly in the horizontal direction, thereby gradually extending the spine, adjustable by a measuring device (from 0 to 100 pounds) [3].

However, this design has significant drawbacks, since the entire lumbar spine is subjected to stretching and there is no direct effect on the damaged vertebra.

The known design does not allow to act quite effectively on the affected segment of the spine, since it only contributes to the straightening of lordosis, and in the proposed it is unbending.

Based on the existing level of designs to correct spinal deformity and eliminate identified deficiencies, the task was set: to provide more efficient reduction of hernia of the spinal disc of the posterior localization due to local direct exposure to the damaged vertebra.

The problem is solved as follows.

A table for traction therapy, containing a base, a working surface, consisting of the chest and pelvic sections, a mechanism for changing the position of the working surface. New in solving this problem is that the chest of the working surface is equipped with a lifting platform. On the sides of the chest of the working surface, vertical screw posts are reinforced. At the free ends of the vertical racks there is a load element made in the form of a wedge, the top of which is oriented towards the lifting platform. In this case, the stabilization of the load element on the uprights is provided by nuts with wing nuts.

We explain the essential distinguishing features of the proposed table for traction therapy.

Equipping the chest of the working surface of the table with a lifting platform allows you to enhance the effect of detension and create more comfortable conditions for the patient by adjusting the height of the lifting platform.

Strengthening on the sides of the chest of the working surface of the table of vertical screw racks allows you to place the load element directly in the place of deformation of the spine in the projection of a hernia of the disk.

Placing a load-bearing element in the form of a wedge at the free ends of the uprights, the apex of which is oriented towards the lifting platform, provides for “wedging” of the spine due to the expansion of the spinous processes, and, accordingly, of the vertebral bodies in the rear projection, which, in turn, eliminates posterior compression of the disc, and also eliminates spondylolisthesis. At the same time, soft tissue edema in the damage zone is reduced, which stops lumbalgia and radicular syndrome.

Patent studies on subclasses A61F 5/01, 5/04, A61G 13/00, A61H 1/00, 1/02 and analysis of scientific and medical information reflecting the existing table designs for manual and traction therapy did not reveal devices identical to the proposed one. Thus, the proposed table for traction therapy is new.

The interconnection and interaction of the essential distinguishing features of the proposed table for traction therapy ensures the achievement of a new technological medical result in solving the task: to provide more efficient reduction of the hernia of the spinal disc of the posterior localization due to local direct exposure to the damaged vertebra. Thus, the proposed technical solution has an inventive step.

The proposed traction therapy table is industrially applicable in the field of practical healthcare. The device is available for manufacture at the present stage of development of the medical industry. The proposed table design can be reproduced repeatedly and does not require the use of exceptional means for implementation.

The essence of the design of the table for traction therapy is illustrated by drawings, where:

- figure 1 presents a General view of the table in side view;

- figure 2 is a view of the table in direct projection;

- figure 3 is a diagram of the application of force during traction using the proposed table design.

The traction therapy table contains a base 1, a working surface consisting of a thoracic 2 and a pelvic 3 sections and a mechanism for changing the curvature 4 of the pelvic section 3. The thoracic part 2 of the working surface is equipped with a lifting platform 5 and vertical screw posts 6. At the free ends of the vertical screw posts 6 placed the load element 7, made in the form of a wedge, the top of which is oriented towards the lifting platform 5. The load element 7 is stabilized on the vertical screw racks 6 using a nut with a wing 8.

The proposed table for traction therapy is used as follows.

The patient is laid on his stomach on the working surface of the table, on the thoracic 2 and pelvic 3 sections, positioning the zone of damage to the spine on the lifting platform 5 so that the damaged segment of the spine is located exactly under the top of the load element 7. The pelvic 3 section of the table is lowered using the curvature change mechanism 4, the angle of inclination can be 25-45 degrees. The lifting platform 5 is installed at a height of 10-15 cm from the working surface of the table, namely the chest section 2. The top of the load element 7 is installed between the spinous processes of the vertebrae. By tightening the nuts with the wing 8 increase the pressure on the load element 7 and on the damaged vertebrae, thereby pushing the vertebrae relative to each other.

Thus, the proposed table for traction therapy in comparison with the known designs allows you to push the vertebrae relative to each other, acting on the back surface of the spine with a locally dosed and stretched in time force at an optimal angle of inclination of the body relative to the damaged segment of the spine, thereby eliminating compression of the spinal disc during protrusion , hernia, spondylolisthesis and reduce the manifestations of discogenic radiculitis.
