[0023] In the embodiment, temperature sensors 8 are provided at the corners of the gallbladder opening, the four corners of the gallbladder top, the center of the gallbladder top, the midpoint of the gallbladder top four quarters, the center of the operator's inner side, the midpoint of the operator's inner four quarters, the center of the operator's side, the midpoint of the operator's side four quarters, the center of the operator's left side, the midpoint of the operator's left four quarters, the center of the operator's right side, and the midpoint of the operator's right four quarters.
