The invention relates to medical equipment, namely to traumatology and orthopedics, and can be used for transosseous osteosynthesis.

Know the device according to U.S. Pat. SN No. 663347, 1984, contains the basis in the form of two longitudinal parts of the form, which are connected by a longitudinal link having a built-in screw-plate. Each longitudinal portion serves as blocks of pins and fixation installed in the bones of the locking rods. In one of these parts is embedded spherical block bearings.

However, the device of few parts and complex support block leads to an increased complexity of the device and reduces its reliability, and the complexity of combining nodes of the device along one axis can lead to the loss of stability of fixation in the treatment process. In practice, this device cannot provide high quality reposition, as well as lengthening the bones of a screw-tightening device, and therefore, the device does not provide a stable osteosynthesis.

In combination with the mobility of the blocks of the tabs relative to the base facilitates replacement of modules or elements in the repair and simplifies the operation.

The distance between the axes of the holes 11 under the locking rods 3 is equal to the height of the beam is M=N, which increases strength and allows the use of the device for patients of all ages.

The length of the guide groove 7 is equal to the difference of the base length L and doubled distance (2L1) from the edge blocks-clamps to the closest point of the bolt hole extreme series, made in the presser plate 9, which increases the convenience of use.

With one of the ends of the screw-coupler 4 is made of an adjusting hole 20 (see figure 5) turnkey having, for example, hexagonal shape.

The device is used as follows.

After you perform a reposition of bone fragments with the drill in the bone fragments in a horizontal plane to form transverse channels under the screw block terminals 3 (for example, under the screws of the Trench). A blocking rod 3 is introduced into these channels and spend two cortical bone layer at a distance corresponding to the spacing of the holes 11 formed in the apparatus adjacent sides of the slide 8 and the pressure plate 9 blocks-clamps 2.

Then put into fragments of bone locking rod 3 is fixed in the apparatus. To do this, enter the blocking rods 3 into the holes 11 blocks-clamps 2, they are weakened when the bolts 17, 18. When this pressure plate 9 and the locking strap respectively extend from hard contact with the slider 8 blocks of tabs that allows you to move freely blocks-clamps 2 on the base 1 and it is easy to enter the ends of the rods 3 into the holes 11. Holes 11 may have a diamond shape, which facilitates the installation allows the use of rods of different diameters, extends the capabilities of the device and improves the reliability of the attachment.

The fixation rods 3 with the device operates by bolts 17 by clamping rods between the plate 9 and the slider 8 blocks-clamps. Moving the locking bars 10 in the cavity 6 of the tee select the coaxial location of the screw holes 13 PLC in the strip 10 and the bolt 17, which fasten the strap 10 with the slider 8 (with the tab 12 of the slide). Thus, the commit block-latch 2 to the base 1. Of all IDNO, that mobility unit-retainer relative to the base need only loosen the bolt 17.

When using the device as a static latch, distractor or acute shortening or lengthening of the bone using the base with two power-holders 2, which is fixed rods introduced into the bone. In this case, the rods are inserted into the bone fragments on different sides relative to the fracture. The fixation rods with machine perform using the block-clamps, as described above. Blocks-clamps connect to the screw-tightening device, passed through holes in the lugs. One of the blocks of the clamps still attached to the base, and the securing strap 10 by the screw 17 is tightly pressed to the bottom wall 11ibeam On another block retainer fixed eye with which the screw-coupler is connected to the thread. This block retainer by loosening the screw 17 the bar 10 is removed from contact with the wall 11ibeam than provide this block-latch mobility relative to the base and rigidly associated with block lock. At 5-7 days after surgery fastening rods introduced into the bone fragments, with the apparatus small turns special hex key (not shown)that interacts with an Allen hole 20 (figure 5), available in screw-coupler 4, which are upholstered with small movements of the rolling block-lock consequently, small movements associated bone fragments. Thus provide compression or distraction of bone fragments in the treatment of fractures or acute segment shortening or lengthening of the bone. Screw-coupler attached on the outside of the devices that are available for configuration, operation, and Assembly-disassembly when repairs and replacement of items. This increases comfort during treatment.

When the elongation of the bones of the patient is easy to ensure that the turns of the screw-screed above the key installed in the end hole 20. The distraction of the segment is done usually in mode 1 mm per day, completing one full turn of the screw-rod. In practice, it is established that the reduction of pain in a patient with lengthening occurs if the distraction to spend 4 times a day 1/4 turn.

In the case of replacement of bone defects after osteotomy, use a device with three blocks-clamps 2 and with a screw-coupler, attached to the two adjacent blocks-place. The ratio of the length L of the base 1 to its height H equal to 17.5:1, allow us to do this for patients of different ages and extends the capabilities of the device.

In this case, the osteotomy is performed in advance. The rod is introduced into fragments on one side of the bone defect on different sides of the osteotomy and fix them accordingly in two blocks-place. Crucial and, put on the other side of the bone defect, fix in the third block retainer apparatus. Two adjacent block latch located on different sides of the bone defect, connect a screw-coupler. Fastening rods in blocks-place perform, as described above. At 5-7 days after an operation key that has been installed in the hole 20, it is possible to perform compression or distraction of bone fragments in the treatment process. When performing the metered movement of the screw-ties of the bone in the direction of convergence of fragments (decrease bone defect) in the plane of the osteotomy is observed dosed self bone regenerate. Gradual filling of the bone defect perform a full restoration of the damaged bone. These extend the capabilities of the device and increase the treatment effect.

Technical and economic effect of the proposed device is to extend the functionality in the selection of the form and parameters of the device, including its weight, providing reliable and stable osteosynthesis in the treatment of fractures, with the substitution of the defect bone after osteotomy and lengthening of the long bones for patients of different ages, while simplifying operations, improving convenience and reducing the time as well as simplifying and reducing the cost of operation is Oia, improving the reliability, strength of fixation and increase the service life of the device.

SUBSTANCE: group of inventions refers to medicine. A device for treating bone fractures comprises a number of levers, a number of joint elements, a mechanical device, a controller and a frame. Each of the levers extends from a proximal end to a distal end and is movable in the three-dimensional space. The proximal end of each lever is connected to the frame. Each of the joint elements is connected to the distal end of the respective lever, wherein the joint element encloses and blocks a bone fixation element attached to the respective bone fragment so that each of the levers is connected to the respective bone fragment. The mechanical device makes the lever move for advance each of the levers in relation to the frame. The controller obtains data respective to a desired final position of the bone fragments in relation to each other and controls the mechanical device to advance the levers in relation to each other for achieving the desired final position of the bone fragments in relation to each other. The frame comprises a long element with a number of levers attached thereto. The long element is configured rotatable to rotate a number of levers in relation to the frame. A method of treating the bone fractures involves: attaching a first bone fragment to a first bone fixation element and a second bone element to a second bone fixation element; connecting a distal end of the first lever with the first bone fixation element and a distal end of the second lever with the second bone fixation element; each of the first and second levers extends between the distal end and proximal end connected to the frame; the frame comprises a long element with a number of levers attached thereto; the long element is configured rotatable to rotate the first and second levers in relation to the frame; obtaining the data corresponding to the desired final position of the first and second bone fragments in relation to each other; and controlling the mechanical device to advance the first and second levers in relation to each other to achieve the desired final position of the bone fragments.
