Fracture operation method and operation instrument of facial bone such as mandible

摘要

(57) Abstract This invention regards the operation instrument for fracture operation of facial bone such as mandible. It inserts the operation instrument, incising the side of the mandible inside the buccal cavity with the external incision of the face, after guaranteeing the space which possesses the distance approximately of 20mm from the surface of the bone, via the buccal cavity. The traction vessel which relates to this invention, from the knob bending with angle approximately of the 45, traction, fixing and cutting is accomplishment possible simultaneously with the activity power of the tip/chip which it appears frequently at the end which becomes, facing toward the semi- annular section and this. The drill driver which relates to this invention is enabled with the replacement of the screw and the drill tip/chip as a drill and a driver. Processing the thin metallic plate where the gripper for the metallic plate fixing which relates to this invention has elastic power to gripper condition, twisting with angle approximately of the 90 vis-a-vis the body section, and this body section which become in order for the wide aspect to become plane surface, consists of with the screw head insertion groove and at the advanced surface of both leg section the metallic plate which is penetrated to both sides it inserts and is packed and the groove which formed the clamp tooth in the point of both leg section and both leg section which it provides.
