INSTRUMENT FOR THE POSITIONING OF AN IMPLANT IN THE HUMAN SPINE

摘要

An instrument for the positioning of an implant into the human spine, as a replacement for one or more vertebra bodies with: - vertebra body plates attachable to the healthy vertebra bodies - distraction rods which at one end are attachable to a vertebra body plate - two U-shaped parts, whose limbs telescopically cooperate and form a tubula r housing around the attached distraction rods, wherein the U-shaped parts comprise inner sections which are supported on the distraction rods and - a distraction instrument which is connectable to the other ends of the distraction rods for exerting a force onto the rods transversely to their longitudinal extension.
