A method for species-specific identification of a Mycobacterium species is provided. When the movable member is moved to a desired position in the X direction, power supply to solenoids is stopped in a clamp mechanism, and a clamp plate presses the movable member against the fixing-side member to fix it. With this tube inserted until its distal end is located inside the trachea, the catheter enters the bronchus to be obstructed. In an embodiment, the navigating automatically the volumetric data is initiated from an interaction by the user. This configuration allows the overall mesial-distal width of the bracket to be reduced, thereby facilitating the bonding of brackets to narrow andor maloccluded teeth.
