Auxiliary supporting device in ultrasonic examination and using method thereof

The invention relates to an auxiliary supporting device in ultrasonic examination and a using method thereof.The auxiliary supporting device comprises a vertical supporting rod, a rotating supporting rod and a supporting unit, the vertical supporting rod is a height-adjustable telescopic rod, and the end of the rotating supporting rod is rotationally connected to the top of the vertical supporting rod; the supporting unit is arranged at the end part of the other side of the rotary supporting rod; when the lung position or the chest of a human body needs to be examined, the arm and the ultrasonic probe can be driven to move along a fixed route through the path guidance of the virtual transverse line and the longitudinal line and the automatic driving effect of the structure, so that the preset route can be well completed to complete the examination, and the examination efficiency is improved. The arm is driven to move at intervals in the longitudinal direction and then continuously and slowly move in each tran
