Description
Technical Field
The application relates to the field of medical equipment, in particular to a bronchus intervention continuum robot facing small pulmonary nodules.
Background
Lung cancer is the most prevalent tumor with increased morbidity and mortality. Early diagnosis of lung is therefore critical for lung cancer treatment. In the early diagnosis of lung cancer, the existence of pulmonary micro-nodules can be diagnosed by combining CT images, but the pathological change of the pulmonary micro-nodules into lung cancer needs to be determined by lung bronchial biopsy. The biopsy mode comprises two modes of lung bronchus interventional biopsy and percutaneous puncture. Percutaneous aspiration biopsy is to determine the location of a lesion in the lung by CT or X-ray scanning, and to obtain a biopsy tissue by passing a puncture needle through the skin of the chest into the lesion in the lung, but percutaneous aspiration biopsy is not suitable for a micronode. Meanwhile, the lung cancer cannot be completely eliminated without detecting cancer cells by taking materials in percutaneous aspiration biopsy, and the risk of false negative exists. Meanwhile, complications such as pneumothorax are also likely to occur. For the lung bronchus interventional biopsy mode, for the central lesion at the lung portal part, the diagnosis accuracy rate of the lung bronchus interventional biopsy is higher, and for the lung nodule outside the air passage, the focus is difficult to reach by the traditional bronchoscope. The lung has numerous bronchial branches and a narrow lumen.
At present, in the biopsy confirmation, the clinical difficulty of accurately extending the interventional lung biopsy exists, and the development of a lung interventional robot is hindered.
