Background
Lung cancer has become the leading cause of death from malignant tumors in china and is one of the most common and deadliest cancers worldwide. According to statistics, the lung cancer incidence rate of Chinese men increases by more than 20% every year, and 50.93/10 ten thousand and 43.24/10 ten thousand of the death rate of Chinese men in 2015; the incidence rate of the lung cancer of the female is 22.4/10 ten thousand, and the death rate is 17.78/10 ten thousand.
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.
At present, for the exploration of the lung marginal trachea, an electromagnetic navigation bronchoscope system can be adopted, but the system is used by means of a bronchoscope and limited by the outer diameter of the bronchoscope, the bronchus in the lung marginal area cannot be directly observed, and meanwhile, the system is expensive in manufacturing cost and is not beneficial to popularization and use.
In recent years, not only the incidence of lung cancer has continued to increase, but also the incidence of pulmonary nodules has significantly increased. Even if the imaging examination such as CT, PET-CT and the like and the invasive examination such as fiberbronchoscope, percutaneous lung puncture and the like are comprehensively used, the qualitative diagnosis of the pulmonary nodules still faces huge difficulties, and a novel pulmonary examination device is needed to solve the problems.
