The invention relates to medicine, namely to traumatology and orthopedics, neurotraumatology and can be used in the treatment of injuries and diseases of bones and joints.

Known bracket for tension spokes: Kirchner, cyto, Ural research Institute, Capitol records (N. P. Novichenko, F. E. Eliasberg, Constant traction, M. Medicine, 1972, S. 25 27).

They contain branches (curved plate), the fastening elements and the tension of the spokes in the bracket, the securing pins in the bone. Staples are used for implementation of targeted skeletal traction in the treatment of injuries and diseases of the long bones.

The disadvantages of the above brackets are:

bend the arc produced by the industry, stand and the magnitude of the cross-section of the segment of the limb in the area of the spokes (too small or "close" bracket with an increase in traumatic oedema of the legs may form a bedsore of soft tissues from indentation branches; too "free" bracket facilitates migration, infection and teething spokes in bone);

given the size of the bracket limits the use of fixtures, fixing and stabilizing the needle in the bone from moving it in the direction of its axis, which causes migration, infection and eruption of spokes;

the latches of the needles in the bones used in these brackets are designed to support soft tissue, which can cause sore soft tissues in their adhesion;

brackets are used only for use in the system voltage spokes.

They contain branches (curved plate), having at the free end of the tip-nozzle for introduction into the bone to a depth.

Staples-terminals are used for implementation of targeted skeletal traction in the treatment of lesions of the long bones.

The disadvantages of the above terminals are:

the invasiveness of the manipulation on Walachian hammer tip-branches into the bone;

cannot be used when the ASS="ptx2">

Known bracket-terminal of the Ural research Institute for skeletal traction for parietal tubercles skull in the treatment of injuries and diseases of the cervical spine (N.P. Novichenko, F. E. Eliasberg. Constant traction, M. Medicine, 1972, S. 33).

It consists of two pivotally connected branches, the ends of which are fixedly mounted cylindrical protrusions with limiter for inserting them in preseve holes parietal tubercles skull.

The disadvantage of this bracket is:

the need for preliminary application rasevych holes with a hand drill or drill in parietal bone;

the complexity and duration of this surgical intervention, its invasiveness;

the need for this operation specialist neurotraumatology;

cannot be used in other systems skeletal traction.

The closest to the invention is a bracket for osteosynthesis containing lateral and transverse plate with holes and fasteners. Side plates along the length have a number of additional openings, and a transverse strap has two rows of additional holes arranged in a checkerboard pattern with lateral and transverse plate with the 120o(SU, and.with. N912158; class A 61 B 17/18, 1982).

Disadvantages closest analogue:

limited opportunity to establish lateral slats in the direction of increasing or decreasing the distance between them depending on the amount of soft tissue limb of the patient in the place held spokes;

the absence of clamp devices, bend the needle, which requires additional instrumentation;

complexity when moving side planks (additional manipulation, time costs);

limited ability to use fixtures that secures the needle in the bone, which can lead to migration, infection and teething spokes;

the inability to use the other systems skeletal traction (for example, when the traction skull).

Object of the invention is a device for universal application, i.e., the possibility of its use in any system, skeletal traction, simplification of fixation and tension the spokes in the device, reliable stabilization her bones, reducing the morbidity and reducing the time of surgical intervention.

When the task is achieved therapeutic effect, which consists in the following:

nigerrima, when applying the device to the cranial vault surgery duration is five minutes, when applying analog 40 minutes of Operative interventions overlay rasevych holes is eliminated, easy application allows you to perform this manipulation by any surgeon.

when using the device creates optimum conditions for successful reposition of bone fragments and the process of reparative regeneration, the possibility of occurrence of decubitus soft tissues.

the proposed device may be used in the system voltage spokes and blending terminals through a removable fastening element on the bottom side of the plate.

The versatility of the device, reducing the time of blending, easy application, no special tools, the ability, if necessary, to do without electricity in extreme conditions, allows us to recommend the device to be used in the conditions of a massive influx of casualties.

To solve this task, side plates pivotally connected to the transverse sliding bar, with holes for rigid fixing it bolt to the required length, by angle due to the gap between the side plates and the ends of the transverse sliding of the strap. The upper ends of the side plates proobraz bent outwards and connected adjustably sliding the Jack sleeve, having a stock length greater than the length of the transverse sliding of the strap. The lower ends of the side plates have square holes for clamps spokes, made in the form of a bolt with a square base and a slot in it for the spokes and screw it cylindrical nut with a through hole for inserting a removable handle with sliding the Jack sleeve. On the needle, after conducting her through the bone, put the stabilizers spokes consisting of a cylindrical tube with a thickening at the end, is fixed in the through hole of the bolt, and screw it elongated cylindrical nut. In the square holes of the lower ends of the side plates, if necessary, fixed removable attachment terminals sharpened triangular sharp ends and limiter in the form of a cylindrical threaded sleeve and nut.

Device for skeletal traction has two side plates 1, pivotally connected with 2 transverse sliding bar having a receiving case 4 with an opening 5 and a sliding bar with holes 6, rigidly fixed on the desired length of the bolt 7 in the holes 5 and 6. Side plates 1 can change the angle of inclination with respect to the transverse sliding plate at a given angle through the gap 26 (2 2) between the side plates 1 and the ends of the receiving case 4 and the sliding plate. The upper end of the side plates 1 proobraz curved outwards 3 and movably connected with the sliding Jack sleeve consisting of two rods 8 with right and left threads and exciting their sleeve 9, having a removable handle 10 and facet 11 for gripping rings. The two connecting rods 8 in cross section have an oval shape 26 (Type-In) under the openings of the upper ends of the side plates 24 (Fig. 2) and end at one end am 8 through the corresponding oval recess 25 (Fig. 2) under the bonnet 13. On the connecting rod 8 between the sleeve 9 and an oval recess 25 has a stabilizing nut and washer 12. At the lower end of the side plates 1 is the bolt-latch needles, G-G, consisting of a bolt with a square base 27 under the square hole 14 on the side plate 1 and slot 18 therein for spokes 19. The bolt is screwed a cylindrical nut 16 with a hole 15 for detachable handle 10 with the sleeve 9. In the base of the cylindrical nut 16 has a washer 17, covering his hole square flange bolt 27, protruding above the side plate 1. The needle 19 is conducted through the bone 20, wearing stabilizers spokes (Fig. 3), consisting of a tube with a thickening at the end 21, is fixed in the through hole of the bolt 22, and a screw therein an elongated cylindrical nut 23. In square holes 14 of the lower ends of the side plates 1, if necessary, fixed removable attachment of the terminals 28 (Fig. 4, d-D), having a three-sided sharpened sharp ends 30 and stopper in the form of a cylindrical threaded sleeve 31 and nut 32.

New in this invention is used in conjunction with sliding of the transverse plate, sliding the Jack sleeve, slidably connected with the side of platismatia angle of the side plate at a given angle (for example, 65oto 125o), it is rational to set the device that stabilizes the needle in the bone, to use the device in any system skeletal traction.

More stock length sliding the Jack sleeve through proobraz curved outwards of the upper ends of the side plates, allows you to fully use the stock length of the transverse sliding of the strap and secure fastening of the ends of the connecting rods in the Jack sleeve. Allows you to fold and unfold the side plate.

Removable attachment of the terminals with sharpened triangular sharp ends and limiter in the form of a cylindrical nut and the locking nut allows to use the device in the system terminal, as the skull and bones; give the opportunity to adjust the length of the protruding tip; exclude pre-overlay rasevych holes on the skull; facilitate the immersion of the tip of the nozzle into the bone.

Device for skeletal traction works as follows. Patients with injuries or diseases of musculoskeletal apparatus according to the usual method is spoke of Krishner 19 through the bone 20. On the spoke with both of its ends to put the stabilizers (Fig. 3) assembled at the end of a pointed scalpel skin is pierced near the spokes for 3 mm Then, in accordance with displacement of the soft tissue of the limb of the patient, the side plates 1 are extended to the desired length. To do this, heed the bolt 7, a little spin stabilizing nut with washer (12) on the connecting rod 8 and the hand, picking up the support 11 of the sleeve 9, spin it the necessary distance so that the pull-out rail 6 extends from the receiving case 4 to the position of the lower ends of the side plates 1, when they would touch the ends 23, mounted on the spoke stabilizers (Fig. 3). This position is fixed on the transverse sliding rod 6 bolt 7, is introduced into the opening 5 at the receiving sleeve 4. Then fix the spoke Kirchner in the bolts of the clamps G G, to which the hand is a bit out of the cylindrical nut 16 with bolts, slid the needle 19 in the slot of the bolt 18 and twist tightly the nut 16 with removable arm 10 with the sleeve 9 by inserting it into the hole of the nut 15 of the latch needles. Again, the handle 10 is inserted into the hole of the sleeve 9 and back strain 19 in the bracket by twisting the sleeve 9 on the connecting rod 8. Stabilizing nut and washer 12 are pressed tightly to the upper ends of the side plates 1. Then by untwisting the nuts 23 of the stabilizer spokes on the bolt 22 are pressed tightly thickened by Conetoe sliding rod 6 and sliding the Jack sleeve at a given angle (for example, in the range from 65oup to 115oprovides a more accurate and convenient adjustment of the distance between the side plates 1, and also allows you to strain the needle 19 or, conversely, to bring together the side plates 1 to each other (for traction for the skull (Fig. 4) when the lower ends of the side plates 1, if necessary, are recorded 5-5 removable attachment of the terminals 28 with stop 31, triangular and ostrozatochennymi ends 30 which are embedded in the parietal bone. For this, in terms of dressing in observance of aseptic pointed scalpel produced puncture to the bone soft tissue in the parietal tubercles, size 7 mm, Introduced into the puncture sharp ends 30 with the stopper 31 of the nozzle-terminals 28, already pre-equipped square hole 29 on square base 27 of the bolt-lock, protruding above the side plate 1 so that the bend 33 of the nozzle-terminals 28 lay on the end of the side plate 1. This provision is tightly fixed by a nut 16. After that, the rotation of the sleeve 9 sbohem the lower ends of the side plates, with triangular and ostrozatochennymi end 30 of the nozzle-terminal 28 is embedded in the parietal protuberance. The rocking bracket in the frontal plane and re-convergence of the side plates achieve that will limit Ormerod passage in the bone. The limiter 31 is set in advance so as to have the necessary Vistana edge 30, and is fixed in this position by a lock nut 32.

If necessary, use on tubular bones stopper 31, the nut 32 can be removed and use the ledge 34 at the base of the tip 30 having a smaller diameter than the remaining portion 35 of the terminal.

A larger supply of distances sliding the Jack sleeve through proobraz curved outwards of the upper ends 3 of the side plates 1 with respect to the transverse sliding rod 6, provides the reliability and durability of the grip ends of the connecting rods 8 sleeve 9 at the most advanced retractable rod 6.
