[0061] When clamping foreign matter, the composite part 72 needs to first pass through the rotary joint 713, and then extend along the middle end insertion part 2 to the outside of the front end bending part 3, and then connect the rotary joint 713 to the quick joint 5, push the push rod 715 to control the piston 716 to slide inside the syringe 711, so that the inner core 722 can slide a certain distance outside the outer tube 721, and the inner core 722 can control the swing of the connecting rod 735 when moving, and then control the rotation of the rotating piece 732, so as to control the jaws 1 733 and the jaws 2 734 to present two states of biting or separation, and the jaws 1 733 and the jaws 2 734 can cut large-sized foreign matter in a continuous opening and closing state;

[0062] When sucking the fluid in the bronchus, by squeezing the airbag 82, the airflow can be blown in the direction of the one-way valve 83, and the airflow will be discharged through the one-way valve 83. When the airbag 82 is in the inhalation state, the one-way valve 83 is in a sealed state. When the airbag 82 is in the inhalation state, the air cavity 10 sucks the fluid in the bronchus into the air cavity 10 under the action of the air pressure difference. As the airbag 82 continuously exhausts and inhales back and forth, the fluid will eventually be sucked into the airbag 82, completing the entire liquid suction operation.

[0063] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
