Abstract
Изобретение предназначено дл осуществлени визуального контрол степени дистракции при увеличении стабильности ее фиксации. Аппарат содержит кольцевые опоры 1, 2 св занные дистрактерами 3, на которых размещены зубчатые колеса 4, св занные кинематической св зью, выполненной в виде кольцеобразного элемента 5, зубчатые колеса расположены на дистракторах 3 парно по обе стороны поверхностей опоры 2 и закреплены посредством втулок 6, выполненных с одной стороны с шестигранными головами 7, а с другой стороны снабженных гайками 8 и контргайками 9, кольцеобразный элемент 5 выполнен цилиндрическим с двум р дами отверстий 10 под зубь 11 зубчатых колес 4 и расположен внутри опоры 2. Вращение одной втулки 6 вызывает вращение зубчатых колес 4, которые посредством кольцеобразного элемента 5 приводит в движение все втулки 6. Происходит перемещение опор по всем дистракторам одновременно. 3 ил.The invention is intended to visually control the degree of distraction while increasing the stability of its fixation. The device contains ring supports 1, 2 connected by distractors 3, on which gears 4 are placed, connected by a kinematic connection made in the form of an annular element 5, gears are located on distractors 3 in pairs on both sides of the surfaces of support 2 and fixed by means of bushings 6 formed on one side with hexagonal heads 7, and on the other side provided with nuts 8 and lock nuts 9, the ring-shaped element 5 is cylindrical with two rows of holes 10 under the tooth 11 of the gear wheels 4 and is located inside 2. The rotation of one sleeve 6 causes the rotation of the gear wheels 4, which, by means of the ring-shaped element 5, drives all the sleeves 6. The supports move along all distractors simultaneously. 3 il.
