Description

Technical Field

[0001] The present invention relates to the technical field of bronchoscope-assisted instruments, and particularly relates to an auxiliary device for bronchoscopy in the respiratory system. Background Art

[0002] When a bronchoscope enters the respiratory tract, it can directly and dynamically observe airway lesions. By observing the morphological structure of the airway, lesions such as stenosis, softening, and foreign bodies can be detected. It can also directly see the degree and scope of airway structure damage complicated by pneumonia, whether there is obstruction by pus and sputum plugs, whether there is bronchiectasis, and whether there is airway stenosis caused by inflammation, etc.

[0003] The therapeutic effect of the bronchoscope is mainly used to relieve airway obstruction, remove necrotic substances in the airway, and can also administer drugs locally. The advantage of bronchoscope flushing and suction is that the bronchoscope can reach the bronchi of the lobe, segment, and below the segment and can be operated under direct vision. During the process of examining and repeatedly taking samples of the trachea through the bronchoscope, repeated insertion and extraction actions are required, and the repeated insertion and extraction actions may cause the bronchoscope to excessively rub against the inner wall of the trachea, thereby damaging the trachea.
