Description

The invention relates to surgical apparatus for repositioning, fixing, functional treatment and eliminating the vicious position of the limb in fractures and false joints of the long bones. Compression-distraction devices are known, which contain rings and arcs, spokes retainers, fastening screws, spherical hinges, fasteners. The purpose of the invention is to ensure the elimination of deformations of the long tubular bones and contractures of the large joints, to maintain a constant size of the joint gap during movements in the joint and their compression fixation. This is achieved by the fact that each pair of clamping screws is connected by a spherical joint, and the rings and arcs are set at an adjustable distance from the plane of the hinges. FIG. 1 shows the proposed apparatus, a general view; in fig. 2 is a view along arrow A in FIG. 1; in fig. 3 - spherical joint node, axial section. The device contains a proximal 1 and distal 2 rings, clamps 3, needles 4 and telescopic pin snips 5. Each of the telescopic clamp screws 5 is rigidly connected to a spherical hinge by one threaded end, which consists of a ball 6, a saddle 7 and a fixing nut 8, and others with nuts and locks 9 - with ring 1 or 2, respectively. The spokes 4 are guided through the bone, secured in the rings by the clips 3 and tensioned with a lead (not shown). The telescopic fastening screws 5 are connected to the holes in the rings 1 and 2 and connected with spherical hinges. When the long tubular bones are deformed, the rings are not set parallel to each other, but so that the axes of the telescopic fastening screws 5, which are perpendicular to the plane of the rings, intersect at the centers of the ball joints at an angle equal to the deformation angle. In this case, all the hinges are in the same plane BB. This is ensured by loosening the clamping screws and unharming them relative to the rings. After installing the hinges, the clamping screws 5 are fixed with nuts and lock nuts 9 to the rings / and 2. Two hinges are located, for example, in the plane BB, passing through the longitudinal axes of the bones and the top of the angle of deformations. -G perpendicular to her. Then. . by dosed gradual screwing into the opposite sides of the jack and lock nuts 9 on the tightening screws 5,
