PROBLEM TO BE SOLVED: To promote efficiency of human power for performing tooth and oral treatment and examination with less practitioner and assistants that conventionally require four hands of the practitioner and the assistant, and also increase the visibility of a mirror thereby enabling easy operation of a suction path pipe and a mirror without help and raising suction force of a suction path pipe.SOLUTION: A tip end 1b of a suction path pipe 1 is flattened, and slanted to a suction port 1a of the tip end 1b. Also, a suction side circumferential edge 2d of a mirror 2 is fitted in a crescent-shaped notch 1d of a lower side vent edge 1c of the tip end to link these top surfaces. Then, a vent channel pipe 3 of a small diameter is penetrated from the outside of the suction path pipe 1, and is opened at the position facing a mirror face 2c of the suction port 1a to enable air blowing. Also, the mirror 2 has the handle 2a screwed to a screw part 1g of the lower outer surface of the tip end 1b of the suction path pipe to be detachable.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2017,JPO&INPIT
