Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a bronchoscope for children and a method of using the bronchoscope. Background Art

[0002] The bronchoscope is suitable for observation of lesions in lobes, segments and subsegments of the bronchi, biopsy sampling, bacteriology and cytology examinations, and can be used in conjunction with a TV system for photography, teaching and dynamic recording. The bronchoscope is equipped with a biopsy sampling mechanism to help discover early lesions and can perform internal surgical operations such as polypectomy. It is a good precision instrument for research on bronchial and lung diseases and postoperative examinations. For children with abnormally deviated and narrow nasal cavities, where it is difficult for the bronchoscope to enter, the bronchoscope is inserted through the oral cavity.
