Bronchoscopy is One of the Most Effective Methods in Diagnosis of Lung Cancer

Bronchoscopy is one of the most effective methods in diagnosis of lung cancer.We have been making researches and developed the prototype of a new Flexible-Broncho-Fiberscope since 1965.At this time of accomplishment of this new fiberscope, we make the report on its specification and clinical experience records, as follows:-A. Specification of flexible Broncho-fiber-scope:1. External diameter: 5mm.2. Total length: 75cm.3. Flexibility of the apex: 180 degrees (Possible bending in the form of “U-turn” by remort control system)4. Attachments of the biopsy needle and the mucous anaesthetic tube are equipped.B. Clinical experience records:1. We have applied the operation of frexible broncho-fiberscope to 148 cases from January to August, 1967.2. 89%of 62 lung cancer cases have been visible with this instrument.3. We have taken motion-pictures of these cases which are to be put on exhibition.
