Description

The invention relates to medical equipment, namely, devices for osteosynthesis.

Known clamp for the spokes to the compression-distraction apparatus, which contains a U-shaped bracket with slots and screws. Moreover, the slots form an asymmetric groove and a recess on the inner opposite groove surface. For fixing more than two or two knitting needles at the same time, a clamping plate with a threaded hole and an insert are provided in the clamp. This clamping provides for fixation of parallel spokes, implementation of the traction of several paired bones simultaneously, and also allows you to install additional spokes without dismantling the device and weakening its fixation qualities [ί] · ^{ν '20}

However, this clamp does not provide quick assembly and installation of the compression-distraction apparatus, which makes it difficult to provide assistance with 25 mass arrivals of victims.

The aim of the invention is to accelerate the assembly and installation of the device in conditions of mass influx of victims. thirty

This goal is achieved in that the clamp is provided with a plate with grooves mounted on the ends of the bracket, the slots are located at the ends of the bracket and are made in the form of rectangular and oval grooves, and the width of these grooves corresponds to the thickness of the plate, and the screw is provided with a spherical abutment pad.

FIG. 1 shows a clip for the spokes to the compression-distraction apparatus, front view; in fig. 2 the same, side view; FIG. 3 - P-image-. naya brace, general view; in fig. 4plate, general view.

The clamp is made in the form of a U-shaped bracket 1, on the lintel of which there is a threaded hole into which the clamping screw 2 is screwed with a hinged spherical abutment pad 3 at the end. At the ends of the U-shaped bracket there are hook-shaped grippers 4 formed by oval grooves in which the needles 5 are fastened. The clip is provided with a plate 6 with slots 7 under the ends of the U-shaped bracket 1. The last one is necessary to press the spokes into the hook-shaped grippers and prevent their deformation by curved pressure the surface of the round ring. On

The side surfaces of the U-shaped bracket are formed by two gifts of rectangular grooves 8, the width of which is commensurate with the thickness of plate 6. The lower pair of rectangular grooves 8 is aligned with the oval grooves of the hook-shaped hooks 4. The grooves on the side surface. collection without knitting needles, as well as without knitting needles and without a ring.

The harness is used as follows.

After treating the patient's skin and anesthesia, appropriate open or closed interventions on the bone fragments are performed. Manual or electric drill through the bone fragments hold the spokes 5. Accordingly, the crosses of the spokes on the limb are mounted ring 9 compression compression apparatus with a circular cross-section. On the rings 9 install U-shaped bracket 1 clamp, then on the lower ends of the U-shaped bracket 1 wear plate with slots above the level of the lower pair of rectangular grooves. In the oval grooves of the hook-shaped grippers 4, the needle 5 is immersed. By screwing the clamping screw 2 into the threaded hole of the clamp as far as it will go into the ring 9, the plate is moved down the bracket and the needle is clamped into the hook-shaped grippers of the brackets. With the help of a special spicenator, the needles are tensioned, after which the needle is finally fixed.

The installation of the clamp on the ring without the spokes, carry out the displacement of the plate 6 in the lower pair of rectangular grooves

8. The clamp assembly is fixed by screwing into the threaded hole of the clamping screw 2. The assembly of the clamp assembly without a ring and the spokes is carried out by shifting the plate b into the upper pairs

5 rectangular slots 8. The clamp assembly is fixed by screwing into the threaded hole of the clamping screw 2.

Thus, with the help of a clamp, convenient and reliable fixation of the spokes without their deformation is carried out, and the installation of the apparatus and the manipulation of bone fragments are significantly accelerated. In addition, the clamp design allows it to be fixed to the ring without the spokes, as well as without the spokes and without the ring; which guarantees the safety of the clamp in the intervals between use on the device.

Claims (1)

Claim 20 A clip for the needles to a compression-diffraction apparatus, containing a U-shaped bracket with slots and a screw, characterized in that 25 in order to speed up the assembly and installation of the apparatus in the conditions of mass casualties, the clamp is equipped with a plate with grooves mounted on the ends of the bracket, the slots are located 30 at the ends of the bracket and made in the form of rectangular and oval grooves, and the width of these grooves corresponds to the thickness of the plate, and the screw is provided with a spherical thrust pad. 35
