For the diagnosis of lung cancer, the current common method is to find the focus through the imaging examination of X-ray film, CT, PET-CT, etc., and then take the tissue biopsy to make the pathological diagnosis clear. For central lesions above the segmental bronchi, the location and extent of the tumor can be observed by bronchoscopy, and tissues are taken for pathological examination. However, the bronchoscope has high difficulty in diagnosing peripheral lung lesions due to the limitation of the caliber of the conventional bronchoscope. For peripheral lesions close to the lung margin, the tissue can be obtained by percutaneous lung puncture for pathological examination, but the lesions have the possibility of pneumothorax and hemorrhage, and are only suitable for lesions close to the lung margin within 2 cm. The focus between the two is often the blind area of examination, visible by CT, and inaccessible by biopsy.
In the existing bronchoscope, the diameter of the thinnest bronchoscope can reach 2.6mm, but the working channel is only about 1mm, although the diameter can reach the 10 th grade of lung bronchus, the obtained biopsy tissue is very small, and the tissue examination of a deeper part is difficult to be performed through an OCT probe, so the bronchoscope cannot be used for the pathological examination of lung marginal tracheal lesions and the diagnosis of peripheral lung lesions.
