Conformal medical ultrasonic sound guide pad with adjustable thickness and length

The utility model discloses a conformal medical ultrasonic sound guide pad with adjustable thickness and length, which comprises a pad block and is characterized in that the bottom surface of the sound guide pad is rectangular, the thicknesses of two sides of the sound guide pad are unequal, the top surface of the sound guide pad is an inclined surface with gradually reduced thickness, and the tangent plane of the side surface of the sound guide pad is a right-angled trapezoid. A bag is wrapped outside the sound conducting pad and can be made of plastic PE (polyethylene), PVC (polyvinyl chloride), silica gel or rubber and the like. Lifting belts are arranged on the two sides of the bag and can lift, move and fix the sound conducting pad. The sound conducting pad can be folded along the central line of the inclined plane, and the thickness of the folded sound conducting pad is increased to form a cuboid. The thickness of the sound conducting pad is gradually changed, areas with different thicknesses of the sou
