Bone screw for medical treatments

Abstract

The disclosure relates to a bone screw for medical treatments. On one hand, the disclosure relates to an anchor screw for orthodontic treatments, which has a head portion enabling tightening or unscrewing of the anchor screw and simultaneously allowing an orthodontic device such as a wire to be hung thereon. An anchor screw for orthodontic treatments includes a threaded portion to be inserted through rotation into the palatine bone so as to form a female thread therein and to fasten the screw to the palatine bone, an intermediate portion extending from the threaded portion and having an increasing diameter, and a head portion extending from the intermediate portion. The head portion has a predetermine width while extending from the intermediate portion and protruding in a direction of a central axis of the anchor screw, and includes a pair of parallel flat surfaces spaced apart by a predetermined distance from the central axis of the anchor screw to tighten and unscrew the anchor screw, at least one opening formed to penetrate through the pair of flat surfaces so that an orthodontic device including a wire can be installed therein, and an insertion slit extending from an inner surface of the opening facing the threaded portion to the outside so that the opening can communicate with the outside.
