Abstract
Изобретение относитс к медицине. Цель изобретени - сокращение сроков реабилитации больных путем обеспечени сокращени времени созревани регенерата. Устройство содержит два телескопически соединенных корпуса 1 и 8, храповой механизм, соединенный с ходовым винтом 16, элементы фиксации корпусов 1 и 8 к отломкам кости. На ходовом винте 16 установлена втулка 13, имеюща наружный 12 и внутренний 14 резьбовые участки, имеющие разное направление резьбы. Внутренний 14 резьбовой участок взаимодействует с резьбой ходового винта 16, а наружный 12 - с внутренней резьбой внутреннего корпуса 8. Втулка 13 зафиксирована при помощи фиксатора 18 относительно внутреннего корпуса 8. При вращении ходового винта 16 внутренний корпус 8 выдвигаетс из наружного 1. После этого происходит расфиксаци втулки 15, она начинает вращатьс вместе с ходовым винтом 16 и своей наружной резьбой 12 обеспечивает возвратное перемещение внутреннему корпусу 8. При этом отломки кости сближаютс . 3 ил.This invention relates to medicine. The purpose of the invention is to reduce the time required for the rehabilitation of patients by ensuring that the regenerate maturation time is shortened. The device contains two telescopically connected shells 1 and 8, a ratchet mechanism connected to the lead screw 16, and fixing elements of shells 1 and 8 to the bone fragments. On the lead screw 16, a sleeve 13 is installed, having an outer 12 and an inner 14 threaded portions having different thread directions. The inner 14 threaded portion interacts with the threaded spindle 16, and the outer 12 with the inner thread 8. The sleeve 13 is fixed with a clamp 18 relative to the inner casing 8. When the spindle 16 rotates, the inner housing 8 moves out of the outer 1. After that unlocking the sleeve 15, it begins to rotate together with the lead screw 16 and its external thread 12 provides the return movement to the inner case 8. At the same time, the bone fragments come closer together. 3 il.
