Description

The utility model relates to medical equipment, namely to the construction of orthoses and orthoses.

Orthopedic devices for the lower extremity are known, in which the thigh, lower leg, and shoe are made of genuine leather, and the supporting elements are metal tires, half rings, and the insole that make up the apparatus frame (see Orthopedic devices for patients 0 and I of clinical groups according to the Central Scientific Research Institute for Hygiene and Epidemiology. Technological instruction TI RSFSR 1-044-74).

The disadvantages include excess weight due to the use of heavy metal tires in them, as well as the need for a laborious manual operation to fit metal tires in the form of a plaster cast by the straightening method, which impairs the strength characteristics of the tires and leads to their premature failure.

Known an orthosis for the whole leg with sleeves made of polymeric materials containing thigh, lower leg and slipper sleeves made on the basis of synthetic resin, the thigh and lower leg sleeves being connected by knee hinges, and the lower leg sleeves and shoe connected by ankle joints (see RF patent No. 2127569, published on March 20, 1999).

The reasons that impede the achievement of the technical result indicated below, when using the known device include the high complexity of manufacturing, weighting of the structure, the use of additional technological equipment.

The objective of this utility model is to create an orthosis for the lower limb from polymeric materials, which provides a technical result consisting in simplifying the design, significantly reducing the complexity and production time, ease and strength of the orthosis.

The specified technical result in the orthosis for the lower limb of polymeric materials is achieved by the fact that it contains sleeves on the thigh and lower leg made of polymeric materials impregnated with synthetic resin, and the liners of the thigh and lower leg are connected by knee joints.

The peculiarity is that the sleeves are made of several layers of a polymer bandage directly on the patient’s limbs and are in the form of a longet with fasteners fixed on their edges, while the knee hinges in the block part have holes designed to fix the orthosis in certain sectors of the amplitude of motion of the patient’s limb, and the legs of the knee joints are fixed between the layers of the polymer bandage, and the ends of the legs of the knee joints are bent at an angle of 90 ° to the main part of the legs of the knee joints from the patient's limb.

As the polymer material, a polymer bandage is used, including woven fiberglass fibers impregnated with a polyurethane resin.

Velcro tapes are used as fasteners.

The essence of the utility model is illustrated by drawings, where in Fig.1 shows the construction of the orthosis, in Fig.2 - knee hinge, type A.

The orthosis for the lower limb made in accordance with medical indications and purposes is an orthopedic orthopedic product made to order for a specific patient. The orthosis contains a sleeve 1 of the thigh and sleeve 2 of the lower leg (Fig. 1) made of several layers of a polymer bandage, including woven fiberglass fibers impregnated with a polyurethane resin.

The sleeve 1 of the thigh and the sleeve 2 of the lower leg are individually made for each patient directly on his limb. The sleeve 1 of the thigh and the sleeve 2 of the lower leg are in the form of a longet with fasteners 3 fixed on their edges, for example, Velcro tapes.

The sleeve 1 of the thigh and the sleeve 2 of the lower leg are connected by knee hinges 4, which are fixed in the sleeve 1 of the thigh and sleeve 2 of the lower leg with the legs 5. The knee hinges 4 have holes in the block part, which are designed to fix the orthosis in certain sectors of the amplitude of motion of the limb of the patient. The ends of the legs 5 of the knee joints 4 are bent at an angle of 90 ° (FIG. 2) to the main part of the legs 5 of the knee joints 4 outward from the limb of the patient.

Apply the orthosis as follows.

In the manufacture of an orthosis, two layers of a polymer bandage consisting of woven fiberglass fibers impregnated with a polyurethane resin are applied to two adjacent segments of the lower limb (thigh, lower leg-foot) of the patient, forming a thigh sleeve 1 and 2 lower leg sleeve. The legs 4 of the knee joints 3 are fixed with several layers of a polymer bandage to the sleeve 1 of the thigh and the sleeve 2 of the lower leg of the orthosis along the lateral and medial surfaces of the knee joint of the patient so that the axis of movement of the knee joints 3 coincides with the axis of motion of the knee joint of the patient.

After hardening of the polymer bandage with an oscillatory saw, cuts are carried out along the lateral and medial surfaces of the thigh sleeve 1 and the lower leg sleeve 2, giving them the shape of a longet. Then the liner 1 of the thigh and the liner 2 of the lower leg are removed from the limb of the patient and the sharp edges of the sawdust are treated, and the lining material is applied to the inner surface of the liner 1 of the thigh and the liner 2 of the lower leg. Velcro elastic bands are fixed to the edges of the thigh sleeve 1 and the shin sleeve 2 by metal rivets.

The model of the knee joints 4 may be different, but preferable with fixing sectors of the bending angles and range of motion.

The ends of the legs 5 (approximately 0.5 cm long) of the knee joints 4 are bent at an angle of 90 ° outward from the patient’s limb to tighten and stabilize the legs 5 of the knee joints 4 in the sleeve 1 of the thigh and sleeve 2 of the lower leg of the orthosis.

The proposed device allows you to completely eliminate gypsum work, the use of additional technological equipment and under optimal conditions provides the manufacture of an orthosis within 1-2 hours.

The cost of manufacturing these orthopedic products is low, and the reduction in the period of temporary disability is significant (30-40%).

Thus, the proposed lower limb support made of polymeric materials has the following advantages:

- lightness: 5-7 times lighter than similarly used orthoses;

- strength: an adequate degree of immobilization was maintained for the entire period of use of the orthosis (observation up to 8 months);

- resistance to moisture;

- high x-ray permeability,

- the absence of allergic reactions in the patient;

- aesthetics.
