The invention discloses a multifunctional visual sputum suction tube for thoracic surgery anesthesia, and belongs to the field of biomedical engineering. The multifunctional visual sputum suction tube for thoracic surgery anesthesia comprises a tube, a negative pressure adjusting assembly is arranged at one end of the tube, a protection tube is arranged outside the other end of the tube, and rolling wheels are arranged on the two sides of one end of the protection tube. The visual sputum suction tube solves the problems that in the using process of an existing visual sputum suction tube, the sputum suction tube needs to be manually drawn during sputum suction, the sputum suction tube needs to be rotated and twisted during sputum suction tube drawing, and when medical staff draw the sputum suction tube, the sputum suction effect is easily reduced due to the difference and change of the rotating speed and the drawing speed. By pinching the anti-skid pieces on the two sides of the pair of rollers, the anti-skid
