Endodontic file for dental endodontic treatment

摘要

The present invention is to provide an endothelial file for dental neurotherapy, which is inserted into a power tool and detachably coupled to a head portion; A tissue removal blade inserted into the patient's root canal to remove diseased tooth nerve tissues by rotation; And a stress distribution unit composed of a helical coil spring rib having the same inner diameter and central axis between the head portion and the tissue removal blade portion, thereby focusing the stress concentration generated due to the rotational resistance generated when the endopil rotates in the root canal. It is configured to prevent and minimize the breakage of the endo file.
