Abstract

Изобретение относитс  к медицине, а именно к травматологии и ортопедии. Цель изобретени  - обеспечение возможности удлинени  костей бедра и голени. Устройство дл  удлинени  кости содержит внутренний корпус 1 и наружный корпус 2, св занные телескопически. На конце 3 внутреннего корпуса 1 установлен фиксирующий винт 5. В пазу 6 внутреннего корпуса 1 установлена зубчата  рейка 7, с которой взаимодействует зубчатое колесо, размещенное во втулке 9. Втулка 9 имеет отверстие, в котором расположен наружный корпус 2. На втулке 9 закреплен редуктор 15, св занный с зубчатым колесом. 4 ил.This invention relates to medicine, namely to traumatology and orthopedics. The purpose of the invention is to provide the possibility of lengthening the bones of the thigh and lower leg. The bone lengthening device comprises an inner body 1 and an outer body 2 connected telescopically. At the end 3 of the inner body 1, a fixing screw 5 is installed. In the groove 6 of the inner body 1, a gear rail 7 is installed, with which a gear wheel interacts that is housed in the sleeve 9. The sleeve 9 has an opening in which the external case 2 is located. On the sleeve 9, a gearbox is fixed 15 associated with a gear wheel. 4 il.
