The setting of the spring 6342 facilitates a better clamping and limiting effect on the suction tube, and the force applied by the spring 6342 is not sufficient to over-squeeze the suction tube.

[0025] The working process is as follows:

[0026] 1. When using the device, the operator needs to clean the handle 1 and the soft tube mirror 5 with alcohol, then inject anesthetic drugs into the patient's nasal cavity or oral cavity, and then turn on the working state of the display screen 4 and the soft tube mirror 5 through the switch 3, and then insert the soft tube mirror 5 into the patient's nasal cavity or oral cavity, and then control the soft tube mirror 5 through the operating rod 2 according to the screen effect fed back by the display screen 4 to confirm the patient's condition;

[0027] 2. After confirmation is completed, the external sputum suction tube is inserted into the limiting tube 66, so that the external sputum suction tube and the exhaust pipe 62 are in a connected state. Then, the staff pushes the push rod 65 to the left, and when the push rod 65 slides toward the left end of the first slide groove 64, the push plate 634 will slide in the second slide groove 633. When the push rod 65 is pulled to the leftmost end of the first slide groove 64, the clamping plate 6343 will be separated from the shell 631, and then the potential energy of the spring 6342 set at the bottom of the fixing plate 6341 will pop the clamping plate 6343 downward, thereby clamping and fixing the sputum suction tube up and down, thereby preventing the sputum suction tube from falling off, and then inserting the hose on the negative pressure machine into the exhaust pipe 62, finally, the sputum suction tube can be inserted into the patient's cavity for sputum suction treatment;

[0028] 3. After use, unplug the suction tube and clean the equipment. The staff will pull the push rod 65 to the rightmost end of the first slide groove 64. During this process, the slope surface set at the right end of the bottom of the clamping plate 6343 will slide with the slope surface set on the shell 631, and then the spring 6342 can be compressed, thereby facilitating the quick and convenient storage of the clamping plate 6343.
