The invention relates to medical technology, in particular, to devices for eliminating the deformities of the spinal column and costal hump.

The aim of the invention is to correct torsional, angular deformities of the spine and costal hump.

To achieve this goal, a scoliosis treatment device containing a telescopic support, couplings, a pelvic anchor, adjustable crossheads, a telescopic support is connected by an axial gear with a retainer that can be axially rotated and hooked, and a rotating slide is attached to the telescopic anvil connected to adjustable crossbars , and a spring rigidly fixed on the basis of a telescopic support. In addition, adjustable crossheads are plates with grooves and movable rib clamps, and the pelvic anchor is made in the form of a staple and an extension with a sleeve.

FIG. 1 shows a device for treating scoliosis, a general view; in fig. 2 is a view A of FIG. one; in fig. 3 - vertebral support, front view; in fig. 4 is a view B in FIG. 1 (pelvic clamp); in fig. 5 - rib grip, general view; in fig. 6 - dozer, general view.

A device for treating scoliosis consists of a telescopic carrier stop including a base 1 (Fig. 1) and a rod 2 on which screw 3 is mounted and fixed by screw 3 sleeve 4 and hook 5. Sleeve 4 is made sliding with splined engagement and fixed by screw 6. Base 1 is connected to the platform 7, on which the kerchief 8 and the worm gear 9 are in engagement with the worm tester 10, fixed with its axis in the hole 11 of the base with a pin 12. To the scarf 8 through the holes 13 (FIG. 4) fasten successively 14 and 15 with multi-directional threads connected by sleeves 16. To the free ends of the strut 15, pelvic clamps 17 are attached in the form of a staple with holes 18 for bone screws 19 (Fig. 4). On the rod 2 (Fig. 1), the assembled slider 20 with the ears 21 is rotatably and longitudinally mounted. Inside the precast slide 20 there is a screw groove for the spring 22, in which the spring 22 can move while rotating. Regarding the slider 20, the spring can be fixed with the screw 23 (Fig. 6). The spring 22 is rigidly fixed to the base 1. In the ears 21 by means of the axes 24, triangular planes 25 are installed, in which also by means of the axes 26 the adjustable crossbars 27 are installed, representing are oval in cross section of the plate with grooves 28 (Fig. 5). In the grooves 28 are installed movable axis 29 with flats 30, fixed relative to the cross member 27 by nuts 31 and 32 and

knurled 33. On axis 29 there is a nut 34 and a left rib clamp 36, which is worn by a groove 35 and also a right rib gripper 37 with a groove. The rib grips 36 and 37 have the ability to engage with each other with tongs 38. Axis 29 ends with a pointed pinch 39 On hook 5 (figs. 2 and 3), a screw 43, nuts 41 and slits 42 are fitted with a holder 43 with a fixed hook 44 and a movable hook 45, which has slots 46, a nut 47 and the possibility of movement along the holder along the groove 48. Hook 5 also has the ability to move along the holder 43 due to the groove 4 9.

A device for treating scoliosis is mounted on the spine as follows.

Two incisions 4-5 cm long expose the wings of the iliac bones posteriorly along the paravertebral lines and impose 50 pelvic clamps 17 (Fig. 4) of the device in assembled form (the axis of the spine is conventionally indicated by a dash-dotted line 51) in such a way that Stretches 15 came out of soft tissues (the border of soft tissues is shown by a dotted line 52). In this case, the extensions 14 and 15 should be as close as possible with the help of the clutch 16. Next, impose a device on the spine of the patient. To do this, make a soft tissue incision on the right or left side (which depends on the type of curvature of the spine) from the spinous processes of the spine to install the hook 5 (Fig. 2 and 3). To do this, the holder 43 with a fixed hook 44 leads under the lateral process 53 of one of the vertebrae 54 (with a weakened screw 40) and tightens the screw 40. Then, under the next vertebra (through one), a movable hook 45 is brought under its lateral process 55 with a weakened nut 47 and put it down. Then, with a loosened screw 6 (Fig. 1) and a nut 41, the plant has a hook 5 under the spinous process 56 of the vertebra 57 (preceding the vertebra 54). The nut 41 and the screw 6 are tightened. Then, with a weakened screw 23 (FIGS. 1 and 6), by rotating the worm gear 9 (using an Allen key), raise or lower the slider 20 until the rib grips are conveniently applied. To do this, on three adjacent edges at the top of the hump and at the bottom of the concavity of the chest on each side, cuts 2-3 cm long are made and spines 39 axes 29 are made into holes 59 made in edges 58 (Fig. 5). right edge 58 and left ribbed grips 58, align them with slots 38 and fix them with nut 34. Then fix axis 29 with nuts 31 and 32. After installing rib grips, fix rotating screw 20 relative to spring 22 by screwing in screw 23. Sections around the device inlets in meters soft fabrics sew and impose

sterile dressings. After that, proceed to the imposition of the necessary loads on the spine through the device.

The load on the spine is imposed gradually, periodically increasing after 4-7 days. The torsion of sleeves 16 (Fig. 1) is carried out to straighten the spinal column, as a result, the stretches 14 and 15 are diverted, and the spring 22 is compressed, exerting its spreading energy on the spinal column. As a result of the spring action, the distance between the pelvic clamps 17 and the hook 5 increases - a spinal column gradually straightens out.

To correct the torsion of the spine, the worm gear 9 is rotated in one direction or another, depending on the direction of the torsion of the spine. In doing so, the spring 22 twists and acquires springy properties in the circumferential direction. The force of the spring twist ultimately acts through the rotating slider 20, the plane 25 and the adjustable crossheads 27 on the rib grips (Fig. 5), a moment of spinal spin is created that affects the spine through the ribs and also through

hooks 5, 44 and 45, mounted on the processes of the vertebrae. Thus, the spine is loaded with a straightening force and an unwinding moment. A gradual return to normal (or a state close to normal) occurs after 2-3 months of treatment.
