The invention relates to traumatology and orthopedics for the treatment of fractures and bone disease.Widely known external fixation device, intended for orthopedic fixation and to hold together the bone fragments. Through external locking device broken bones are fixed in their mutual position so that the healing could occur in the correct position. To do this, in bone or inserted through a bone bone nails, preferably with a thread (e.g., screws Trench or arched rods), and are interconnected at their projecting from the body ends, at least one element in the form of a rod, such as a sliding or guiding rod. This connection is clamping elements made in the form locking elements, hinges and, if necessary, in the form of ball joints, couplings or Barashkova items or so on, Thus, can be formed frame konstruksiyali device and the clamp rods such frame construction is relatively unstable, shaky and movable in and of itself, as mutual be holding the rods have to ease into the clamping elements to set them in correct position. So, placing the locking device cannot be done by one person, and requires other assistants who have to keep the hinges and frame. To facilitate this work, can be used a special clamping device. Since steel has a very high coefficients of elasticity and smooth surface, it is impossible by tightening the clamping screw to achieve only a weak clamp. Because of the high coefficients of elasticity even a slight rotation of the adjusting screw causes a very large change in the clamping pressure. Therefore, when fitting the locking device rods, bone nails and screws can only loose in the clamping elements. Added to this is also that used for the fixing device elements change radiographs. In addition, the cost of manufacturing such fixing devices is very high.Predominant is the use of a metallic element which forms the locking device depending on the individual requirements of the surgeon. To the ski materials.A device for immobilization and/or fixing the limbs of humans and animals having pairs of opposite connecting parts, receiving at least one bone screw or one bone nail, which are connected to threaded clamping elements with connecting rods. During this fitting, clamping elements and connecting rods, as well as the unified coupling castles made of reinforced fibers of thermoplastic synthetic materials.Known orthopedic device for fixation of fractures containing at least one above the limb of the patient tubular element, connected via a bone pins or similar enshrined in various bone fragments. When this tubular part and the pins form a stationary frame, holding the fragments in the desired splicing position, and the tubular element includes an elongated flexible support form cured material, existing in the support with an inert fluid.It is also known external locking device comprising at least one flexible, in the form of a tube part of synthetic material, nails or screws fixed in different bone fragments, while filled with cured material part in the form of a tube after curing material forms with knitting needles, nails or screws in a durable design that holds together the bone fragments to splice in the desired position, and some in the form of a tube consists of a synthetic material, and in the cavity of a closed system of tubes is injected synthetic material. Apply these cured materials, which otverzhdajutsja under the influence of visible or other light, some in the form of a tube filled with cured material wrapped opaque outer coating that for the hardening process is removed. As a synthetic tube is applied wave tube, which provides the change in cross-section, if the tube should be placed in different planes and twisted. However, United with fragments of bones, nails and needles cannot poke through the plastic tube, as in this case, which is in the cavity synthetic tube cured material could leak. For the reception of wires, nails or etc., serves as the connecting pipe.Chrome is omery synthetic material. To varying degrees, all homogeneous synthetic materials have only a small tensile strength while at the same time a small elasticity. Hence the need for large cross sections of the carrier tube retainer, with no guarantee that the latch at peak load will not break. It should be added that the mixing synthetic material already filled tube carries many disadvantages: risk of incomplete mixing, the probability of remaining under certain conditions, toxic monomers in the retainer, the lack of a guaranteed constant cross-section of synthetic material, in particular, when the tube retainer arranged in numerous turns, the output of synthetic material from the perforations nails with loss of substance and stability. When cured by heat or radiation arise the following problems: polymerization with radiation only surfaces, the need for infrared radiation to penetrate through a system of tubes lying near the level of the skin (2-5 cm), from which it is necessary to protect the patient. Ultraviolet light instead of infrared, you can make hodnoceni hard.The purpose of the invention is the elimination of these disadvantages increase the reliability of fixation of the bone fragments and the increase in the rigidity of fixation of bone fragments.In Fig.1 shows in schematic form the outer locking device, superimposed on the two bone fragment; Fig.2 in schematic form of a locking device consisting of a bent loop, a tubular element connected At-(or T-)shaped detail for the case of fixation of bone fragments spokes; Fig.3 the adapter of Fig.4 view And Fig.3; Fig.5 a longitudinal section in Fig.3; Fig.6 retainer in the form of a harness for securing the V-shaped curved spokes; Fig.7 the latch for the case of fixation of bone fragments transosseous pin; Fig.8 a cross-section in Fig.7; Fig.9 the latch for the case of fixation of bone fragments sleeve with an external thread with transosseous core in the inner channel of Fig.10 section b-B in Fig.9; Fig.11 is a longitudinal section of the hammer for the introduction of a sleeve with an external thread; Fig.12 spiral cut tubular element filled with rolled fiberglass; Fig.13 section b-b of Fig.12; Fig.14 section area of the tubular element made of synthetic material placed in the Cabinet glass cloth trubka the military cured material with the lumen; in Fig.17 the slit tubular element with a housing of synthetic material reinforced with fiberglass, and Fig.18 the slit tubular element with a housing made of synthetic material with glass fibers.The outer locking device comprises a frame 1 in the form of a flexible synthetic tubular element 2 with the lugs 3, at least one adapter 4 connecting tubular elements 2 and percutaneous rods 5 tabs 6 mounted on the tubular elements.The adapter is made in the form of nuts 7 with opposite thread ends: right and left L, which are connected to lugs 3, made in the form of glasses with an external thread corresponding direction and the pipe 8, in which the projections 9 for fixing a tubular element 2.
