TELESCOPIC ROD OF EXTERNAL BONE FIXATION DEVICE

摘要

PURPOSE: A telescopic rod for controlling the length in an external fracture fixation device for external fixation of a bone fracture to treat is provided which improves the stability and fixation force of the external bone fixation device and imparts the clear X-ray photograph of a fractured portion. CONSTITUTION: This telescopic rod comprises: a screw rod(12) formed by a head part(26) on its one end; a movable hollow shaft(14) which is constructed outward to the screw rod, moves in the opposite direction of the screw rod according to the rotation of the screw rod and formed by a sliding groove in the longitudinal direction on its outer peripheral surface; a stationary hollow shaft(16) having the head part placed adjacent to the head part of the screw rod and a relative motion only in the longitudinal direction; a first connector(18) coupled to the side of the head part of the screw rod; a second connector(20) coupled to the movable hollow shaft; and a cap assembled body(22) which is fixed to the head part of the screw rod and coupled to the stationary hollow shaft to be freely rotated.
