ROOT CANAL INSTRUMENT HANDLE MADE OF TWO CO-AXIAL PORTIONS JOINED IN AXIAL TRANSLATION AND IN ROTATION

摘要

The invention relates to a root canal instrument handle of rotating endodontic type, for example a bur shank, comprising at its end, intended to engage in a driving assembly of the head of a headpiece or a counter-angle, an annular groove and a flat section to engage with an additional means for axial linkage and rotating links provided in the driving assembly, a handle characterized in that it is made up of two co-axial portions in which an internal part (3) and an external sleeve covering the internal portion at least on a portion of its length, a means being provided to fix the sleeve (2) to the external portion (3) in axial translation and rotation, in that it comprises translational and rotational blocking means to engage with a root canal instrument. To easily identify an instrument, it can be provided that for a given instrument, there is a match of a given combination of colors of the two portions of the handle.
