Abstract

The device for extending the long bones contains the outer housing and the inner hollow extendable housing connected telescopically and designed with the protrusion and the groove. The openings in the housings are intended for the fixing screws attaching them to the bone fractures. The outer housing is connected with the ratchet-and-pawl comprising the drive ratchet toothed wheel, the driven ratchet toothed wheel, the stop gear, the traverse screw disposed inside the housings, the supporting ring for the traverse screw designed as a whole piece with the outer housing, the telescopic piston-rod with the ball hinged with the drive ratchet wheel of the ratchet-and-pawl, the latter in its turn is connected with the outer housing by means of the bayonet joint. The end of the housing of the driven ratchet wheel is equipped with the ratchet teeth geared with the ratchet teeth of the driven ratchet wheel sleeve. The stop gear is designed as the stop sleeve equipped with the ratchet teeth from one side for connection with the sleeve of the driven ratchet wheel and the flange matched with the groove – from another side. The groove is made in the stop ring for the traverse screw. The flange in the inner housing is designed as the half-prismatic dowel.
