Abstract

Usage: in medicine for the operative correction of spinal deformity. SUBSTANCE: device for correction of spinal deformity contains a rectangular frame made with the possibility of changing the longitudinal size and consisting of two U-shaped parts, each of which is pivotally connected to the knots for fixing the spokes. 1 ill.

Description

The invention relates to the field of medicine, in particular to devices used in the operative correction of spinal deformity, as a device for performing distraction.

A device for correction of the spine is known, comprising a frame made in the form of guide rods connected at the ends by arches, hooks and hook holders, and a hook holder with a hook with the possibility of vertical movement is mounted on one of the arcs - we take it as an analog.

But the known device does not allow for permanent external correction of spinal deformity with the exception of trauma and pressure sores, and also does not allow longitudinal distraction in the frontal plane.

A device for correcting the spine is known, consisting of two guide rods having a screw thread,

and at one end of the connecting axis, cutting gears are made, in addition, the device is equipped with wires of vertical movement, connecting with arcs, in the slot of which a hook holder with strain gauges is installed - we take for the prototype.

But the known device cannot be used for external correction of spinal deformity (distraction) in the presence of a hump, which is an integral part of scoliotic spinal deformity in the thoracic region of children with II-IV degree of scoliosis. Those. at those deformities when the question is decided in favor of surgical treatment.

In addition, a knot for fixing spokes is not provided in the known device.

An object of the invention is to provide a predetermined dosage load on a patient's spine during scoliotic deformity.

The goal is achieved in that the rectangular frame consists of two U-shaped parts, each of which is pivotally connected to the knots of the knitting needles.

The drawing shows a device for correcting spinal deformity in two projections.

The proposed device consists of arcs, the construction of which is made integral: consisting of a central fixed element 1, to which two U-shaped movable elements 2 are pivotally mounted with the ability to move each around the longitudinal axis 3 from 0 to 90 °, and the guide rods 4 contain a sliding element (actuator), made telescopically in the form of a threaded sleeve 5, inside the guide 2 and a nut 6, limiting the necessary diffraction.

The fixed element 1 for fixing the needles 7 contains a central hole 9 under the holder 8 (the latter has a rectangular nut 10 for fixing the needles 7 in the slot 11), in which the external threaded nut 12 is placed for fixing the spoke 8 in the fixed element 1.

The slot for the needles 11 in the spoke holder 8 is made at an angle to the base (to the site).

Method of use. After the operation is completed, the supporting elements are inserted behind the arch of the vertebrae and the needles are inserted into the cranial and caudal sides transdermally, followed by suturing of the wounds, the proposed device is installed.

The rectangular nut 10 is relaxed with the possibility of inserting the knitting needle 7 into the slot 11 (the oblique arrangement of the slot 11 is provided so that it is possible to fix the needle at a different distance from its exit, since the farther from its exit, the higher the height from the skin knitting needle). The external threaded nut 12 is also relaxed (which allows, thanks to the ability to rotate the spoke holder 8 along the axis, to fix the spoke even when they are not aligned, i.e. the principle of the apparatus to the spoke is maintained, and not vice versa).

Then the knitting needles are planted in the slot 11 (indents 1-2 cm from its exit from under the skin), center coaxially to its direction by turning the spoke holder 8 and clamp with

on both sides with a rectangular nut 10. Then, the established position of the spoke holders 8 is fixed to the fixed element 1 with a special key using a threaded nut 12.

After fixing the spokes with the proposed device, of which one of the spokes is calibrated, the necessary distraction is carried out by tightening the nuts 6 by the required amount (with X-ray control of the correction of spinal deformity in dynamics).

It should be noted that when applying the device, in order to prevent pressure sores in the presence of a pronounced hump, one

from the U-shaped halves 2 is raised by the required amount (for example, 1-2 cm from the skin surface). The predetermined position is maintained during the distraction due to the created distraction voltage.

Thus, due to the design features of the device, the latter allows for multiple correction of spinal deformity before the child's growth is completed, the occurrence of pressure sores on the skin of the knitting needle during distraction is eliminated, correction is maximally dosed, and there is no need to apply a gypsum corset,

there is the possibility of correction of the spine and in outpatient settings, minor injuries of repeated correction.
