VERTEBRAL REPLACEMENT AND DISTRACTION DEVICE FOR PLACING SAID IMPLANT

摘要

The invention relates to a vertebral replacement device comprising two longitudinal elements which are slidingly mounted in relation to each other, and locking means (8), comprising an anchoring surface (10) on one of said elements and the following items on the other element: an anchoring element (12) which is translationally guided in order to assume a first position wherein the elements slide freely between themselves and a second position wherein the anchoring element (12) cooperates with the anchoring surface (10) in order to lock the elements, and a system (15) for transforming a rotational movement into a translational movement transmitted to the anchoring element (12).
