WITH

The invention relates to medical technology, namely to devices for the surgical treatment of diseases of the spine.

The purpose of the invention is to provide control over the correcting effect on the spine during the treatment process by bending the elastic plate,

FIG. 1 shows a device for treating spinal curvature with a partial section; in fig. 2 shows the installation of the device on the spine.

The device comprises a rigid threaded rod 1 and a curved elastic plate 2 pivotally connected to each other by ends. At the same time, holes 3 and 4 are made in the bent ends of the plate 2, through which a threaded rod 1 is held, having a spherical thickening 5 at one end. At the opposite end of the threaded rod 1 there is a nut 6, a coil spring 7 and a sleeve 8, which cooperates with the bent end of an elastic plates 2. In addition, the device contains transverse strips 9 and 10 movably mounted at the ends of the elastic plate 2 in openings 11 and 12. On the transverse strips 9 and 10 there are support elements in the form of hooks 13 with stop plates 14 and nuts 15.

The device is used as follows.

At the borders of the curved part of the spine, two transverse incisions 16 and 17 are made, exposing the spine. From the curvature of the spine and on top of it make a subcutaneous tunnel, through which the conductor passes the plate 2 from the curvature of the spinal column, is installed into the holes 3 and 4 of the threaded rod 1. Through the hole 12 of the plate 2 in cross section 16 transverse bar is held, on which they wear under the nut 15, the hook 13, which is hooked to the transverse process 18. On the other side of the transverse bar 10, the thrust plate 14 is fastened, the hook 13, which is hooked to the transverse process 19, and the nut 15 is screwed on.

Similarly, a cross bar 9 is installed through the cross-section 17 and a hook 13 is put under the nut 15, hooked onto the popeche process 20. On the other side of the bar 9, a thrust plate 14, hook 13 hooked to the transverse process 21 is put on, and a nut is screwed 5 to 5 15.

Further, screws 15 are screwed onto the ends of the strips 9 and 10, firmly fastening the ends of the plate 2 to the periphery of the curved portion of the spine.

In this case, the elastic plate 2, pressing its convex middle part to the vertex of the curvature of the spine, creates a constantly acting extension force on the curved spine, spreading its pathological curvature.

g After fixing the ends of the plate 2 on the spine, the cuts 16 and 17 are clamped, leaving a small hole at the top for the sleeve 8, through which the end of the rod 1 is passed. When tightening the nut 6 to the end of the rod 1, the spring 7

0 compresses and presses on the sleeve 8, and through it on the upper end of the plate 2, which at the same time bends like a bow and, giving the spinal curvature with its middle part to the top, straightens its pathological curvature.

In the course of treatment, the rotation of the nut 6 regulates (strengthens or weakens) the pressure on the curvature of the spine as needed, thereby without additional surgical intervention.

l intervention actively correct the curvature of the spine.
