Description

The invention relates to medical orthopedic technology and can be used in the treatment of pathology of the cervical spine due to curvature of its shape due to injuries, abnormalities and degenerative-dystrophic processes.

A device for the treatment of pathology of the cervical spine [1], comprising a detachable frame in the form of two coaxially arranged with elastic rollers fixed to them and connected by elastic elements, and the elastic elements are made in the form of arcuate wires. The disadvantage of this device is that it allows you to electively affect either one or the other half of the cervical spine by adjusting the tension of the cables. The device is difficult to control the timeliness and dosing of the corrective effort.

Closest to the proposed device is a device containing two coaxially and opposite disposable detachable support sleeves connected by wire elements made of titanium nickelide superelastic, symmetrically and motionlessly fixed by end sections to adjacent sections of the support sleeves between the points of projection of the occipital protuberance and the angle of the lower jaw . Active elements are made in the form of identical flat meander structures with smoothly articulated arched elements [2]. The disadvantages of the known device are:

1) the use for the manufacture of the upper and lower sleeves of simulated plastic (polyvic), which is initially given the shape and which it retains during the treatment, which increases the discomfort when wearing the device during a fairly long course of treatment, reduces the quality of life of the patient. It leads to the appearance of irritation on the skin surface of the neck as a result of sweating of the skin and its maceration;

2) the execution of active elements in the form of flat meander structures with smoothly jointed arched elements limits the amplitude of the normal working movement of the elements, an increase in the amplitude of movement leads to its bending in space and the violation of its functional properties necessary to maintain the magnitude of the corrective action.

A new technical task is to improve the operational characteristics of the device, which allows to simplify control over the magnitude of corrective efforts and increase convenience when used in the treatment process.

To solve this problem, in a device for treating pathology of the cervical spine, containing two coaxially and opposed disposable detachable support sleeves connected by active elements made of superelastic titanium nickelide, located symmetrically and motionlessly fixed by end sections to adjacent sections of the support sleeves between the projection points on them occipital tuber and the angle of the lower jaw, sleeves are made of layer-by-layer connected high-pressure polyethylene and foam rubber, on a layer of polyethylene recesses-pockets are placed according to the place of fastening on the sleeves of the active elements, the active elements are made W-shaped and contain a top, first and second legs of the same length, with the top and ends of the legs made in the form of at least one coil of spring, the ends of the turns of the legs are provided fixed support plates of a rectangular shape made of dense material, the active elements are also oriented anteriorly with their vertices, while the entire device is placed in a protective case, are proportionate size and containing fasteners.

The device for the treatment of pathology of the cervical spine, shown in Fig.1, 2, contains: two coaxially and opposite opposed detachable support sleeves 1, 2 connected by active elements 3 made of superelastic titanium nickelide, located symmetrically and fixedly fixed by end sections to adjacent sections of the support sleeves between the projection points of the occipital protuberance and the angle of the lower jaw on them, the sleeves are made of layer-by-layer connected high-pressure polyethylene and foam rubber, the size of the polyethylene layer There are recesses-pockets 4 according to the place of fastening on the sleeves 1, 2 of the active elements 3, the active elements 3 are made W-shaped and contain a vertex 5, the first and second legs of the same length 6, with the vertex 5 and the ends of the legs 7 made in the form of at least than one turn of the spring 7, the ends of the legs are equipped with fixed support plates of rectangular shape 8 made of dense material, the active elements 3 are also oriented with their vertices 5 anteriorly, while the entire device is placed in a protective cover 9, are proportionate size and containing fasteners 10.

The W-shape of the active elements 3 made of superelastic titanium nickelide is chosen optimal for maintaining a given direction vector of the corrective force without the appearance of undesirable deformation, depending on changes in the amplitude of movement, reduces the possibility of displacement of the device on the patient’s neck, maintains a given corrective force to obtain a stable therapeutic effect. The use of removable fixing of the active elements 3 on the support sleeves 1, 2 by tightly inserting the support plates 8, which are equipped with the ends 7 of the legs of the active elements 3, in the recesses pockets 4 of the support sleeves 1, 2 allows, if necessary, changing the amount of corrective effort, it is easy to change work items. The implementation of the support sleeves from layers of high-pressure polyethylene and foam instead of plastic (polyvic) makes wearing the device in the process more convenient, comfortable. In order to increase convenience and prevent possible engagement of the hair or clothing elements of the patient, the device is placed in a cover made of cotton fabric, equipped with Velcro clips.

The device operates as follows. By breeding the ends of the support sleeves, the device is mounted on the neck with support on the base of the patient’s neck and is fixed with Velcro on the back. In this case, the active elements are in a state of stress. The decompressing effect of the device is carried out gradually, steadily for the patient.

The attainability of the technical result is confirmed by specific examples of the clinical application of the proposed device in an orthopedic clinic in Tomsk.
