A constructive improvement in a device for removing fragments of endodontic instruments inside the root canal of a tooth is disclosed, which improvement represents a solution that makes it possible to minimize the need of aggressive and traumatic interventions to the tooth body, thus reducing the intervention time in view of the practical and easy way the operation is handled, to be applied to any type of fragment generated by an endodontic instrument, which improvement is represented by a device for removing fragments (1) which is comprised of a handle (2) that provides the device with support and rotational movements for removing fragments (6) through a bidigital contact, said handle being attached to a rod (4) the function of which is to connect the handle (2) and the active spiraled tip (4) that provides the coupling to the fragment (6), said coupling being made easier by positioning a guide tip (5) at the end of the active spiraled tip (4) which, once properly locked to the fragment (6), makes it possible to remove same from inside the root canal (g) by means of rotational movements. |
