Description

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

Analogs: It is known "Device for reposition and compression of bone fragments of the patella" (A. S. 1621903, class A61B 17/56, publ. 23.01.91. BI 3), used to reposition fragments of the patella. The device has a repair mechanism consisting of a threaded rod with a screw inside and a support platform. A cone with a rotary ring and handles rotates along the thread on the rod. The rod has a flange with crackers, on which four levers are mounted with thrust elements in the form of blind bushings, bolted to the levers. The ends of the bushings have loops on which hooks with pointed ends are semi-movably fixed.

A device is known: “Reponator” (A.S. 1618401, class АВВ 17/58, published on January 7, 91. BI 1), which is used to simultaneously fix and correct fragments with the creation of the necessary distraction between them. The device consists of two intersecting branches, connected in pairs by plane-spherical hinges, having handles with cremalleres. The ends of the branches are equipped with spikes. Flat spherical joints are connected by axles to a tightening nut and a coupling that tightens the ends of the axes.

A device is known: “Repositioning forceps” (Shmulevich M.V., Milyukov A.Yu., Pronskikh A.A., Bogdanov S.V., Gilev Y.Kh. (Patent No. 2195211, Classes of patent А61В 17/28, А61В 17/56 2000128612/14, filing date 11/16/2000, publication date 12/27/2002) consists of two handles, bent at an angle of 150 °, which are interconnected by a folding hinge. At the ends of the handles there are oval ring handles that allow easy manipulation with tweezers using the fingers of one hand, a high-speed self-locking lock allows you to fix the handles in the right position. jaws with an angle of 20 ° between them in the closed position and 50 ° in the open position are married. The distance between the jaws in the closed position is 60 mm, in the maximum open position - 170 mm. There are two pairs of U-shaped bent legs on the branches, then there are two legs on each branch, four cylindrical thickenings with flat supporting platforms, with sharp conical spikes located in the centers, are made on the legs. The diameter of the flat bearing pads is 10 mm. The length of the spikes is 4 mm. The distance between the centers of the flat supporting platforms on the upper jaw is 12 mm, on the lower jaw is 36 mm. U-shaped legs are located on the branches so that the distance between the spikes of one pair of legs is less than the second pair of legs opposite to them, and in the closed position of the tongs they are located so that one pair of legs is located in the closed position inside the other pair, then there are formed an inner and outer pair of legs. All four supporting platforms lie in one plane, while the distances between the spikes located in the center of each platform are equal, and in the open state during operation, each pair of supporting platforms lies in its own plane.

Criticism of analogues:

- There are no supporting elements that prevent further perforation of the cortical layer of the bone with spikes with pointed ends;

- For reposition of fragments, additional effort is required from the surgeon;

- Designs do not create an effective lever when performing reposition, as they are small in size, providing effort only in the fracture zone.

Prototype: The “Combined method of reposition and fixation of long tubular bones during skeletal traction” is known (RF Patent No. 2192194, Class A61B 17/56, A61F 5/048, application number No. 98112440/14, application filing date 06/26/1998, publication date 10.11 .2002) by means of a tire consisting of a U-shaped frame on which the nodes for fixing the damaged segment of the limb are located: the foot rail, the popliteal grip, has reponent nodes, at the ends of which reposition-fixing elements are fixed that allow you to set the desired direction of reposition of the fragments eliminate their displacement in three mutually perpendicular planes, each fixing unit and repositioned in assembly is movable relative to the frame in three mutually perpendicular planes fixable in selected positions. The popliteal grip is made of two arcuate stops on one side connected by a flat hinge, and on the other a belt with a buckle. The stops on the inner surface are lined with soft gaskets, and from the outside they are connected through flat hinges, rods and loops with telescopic rods. The last connection is made through sliding couplings, in the loops of which the ends of the rods rotate. Couplings are fixed on telescopic rods with locking screws. The rods in the hinges are fixed with nuts screwed onto the threaded ends of the rods on both sides of the hinges. The foot assembly consists of a channel-shaped base, in the lateral backs of which there are blind cuts and under the threaded ends of the rails of the U-shaped frame, on which fastening nuts are screwed on both sides of the walls. On the outer plane of the base, a footplate is mounted semi-mobile with a thrust bearing. Spoke holders are threaded rods, with holes for the ends of the spokes with bearing pads. Threaded studs are passed through loops of U-shaped frames and telescopic rods sliding along the rails. The threaded rods with the help of couplings are fixed in the distal part of the tire on the rails of the U-shaped frame with nuts screwed from both couplings. The threaded rods and with the help of couplings are fixed in the proximal part of the tire on telescopic rods with locking bolts screwed into the couplings. The threaded rods are fastened, screwed onto the ends on both sides of the loops. For ease of use and transportation, another arc is provided. This arc is at the same time a clamp for the parallel relative positioning of the threaded rods and the U-shaped frame and telescopic rods and can be located above and below the tire frame. It is mounted on couplings with locking bolts with the ability to move along telescopic rods with locking screws attached to them. At the ends of the telescopic rods facing the rail, there are flange nuts for axial movement of the telescopic rods (sliding and sliding) along the threaded rods.

The disadvantages of the prototype device are:

- A large number of elements requires significant time spent on the layout of the structure, which complicates reposition.

- The additional use of knitting needles with thrust pads increases the risk of complications: teething and suppuration of soft tissues, after reposition.

An example of a specific implementation: Patient D. (33) underwent osteosynthesis of the right lower leg with the Ilizarov apparatus. Due to violation of the regime, after a month and a half, there was suppuration of soft tissues in the area of the spokes. The structure was dismantled and a plaster cast was applied. The patient continued to break the regime, load the limb, which led to deformation at the level of the fracture. To eliminate it, the proposed “Device for closed reposition of lower leg bones” was used. The foot lying on the couch, the patient was placed in the foot (Fig. 1, pos. 25; Fig. 3, pos. 25), profile 23 cm long, 1.5 cm wide, 3 cm high (Fig. 1, pos. .1; Fig. 2, Pos. 1; Fig. 3, Pos. 1) are placed on the front surface of the lower leg, so that the stop (Fig. 1, Pos. 2; Fig. 2, Pos. 2; Fig. 3 , pos.2) was located in the upper third and the emphasis (Fig.1, pos.5; Fig.2, pos.5; Fig.3, pos.5) was located in the lower third. Then they connected the foot (Fig. 1, pos. 25; Fig. 3, pos. 25) with the frame (Fig. 1, pos. 1; Fig. 2, pos. 1; Fig. 3, pos. 1) by means of a rod ( figure 2, position 13; figure 3, position 13), rods (figure 2, position 14; figure 3, position 14), rods (figure 1, position 28, figure 2, pos.28), rods (Fig.2, pos.29, Fig.3, pos.29) and moved the slider (Fig.1, pos.4; Fig.2, pos.4; Fig.3, pos.4 ) so that the replacement plate (figure 1, item 34; figure 2, item 34; figure 3, item 34) was located at the level of the fracture. After installation is complete, by rotating the nut (figure 1, position 30, figure 2, position 30), nuts (figure 1, position 31, figure 2, position 31), nuts (figure 2, position .32, Fig. 3, pos. 32) and nuts (Fig. 3, pos. 33) approximated the replacement plate (Fig. 1, pos. 34; Fig. 2, pos. 34; Fig. 3, pos. 34) to a profile 23 cm long, 1.5 cm wide, 3 cm high (Fig. 1, Pos. 1; Fig. 2, Pos. 1; Fig. 3, Pos. 1) and, focusing on the crest of the tibia, eliminated recurrence. After control x-ray, the device was removed and the limb was fixed with a circular plaster cast.

From the known structures intended for closed reposition of the lower leg bones, this device is characterized in that:

- Does not contain sharp elements that can perforate the bone;

- Does not require additional effort from the surgeon to perform reposition;

- Creates an effective lever when performing reposition, as it has stops that ensure the application of efforts both in the fracture zone and at a considerable distance from it;

- Contains few elements and does not require significant time for layout;

- Not intended for the use of additional elements involving the perforation of the skin and bone;

- It can be used for closed reposition of other tubular bones.

The technical result of the proposed utility model is the elimination of recurrence of the lower leg bones.
