The application provides a lung segment bronchus catheter, which comprises a catheter tail end ventilation and suction interface, a cuff inflation device, an outer tube, an inner tube, a front end cuff and a guide end formed by the inner tube; the cuff is annularly arranged on the outer surface of the catheter head, and is in the form of a ring ball wrapped around the inner tube in the inflated state; the cuff inflation interface and the cuff inflation conduit are communicated between the gap between the outer tube and the inner tube at the catheter tail and lead to the cuff; the catheter ventilation and suction interface is communicated with the inner tube and the guide end formed by the inner tube, and a guide wire is arranged in the catheter ventilation and suction interface to form a straight lumen. The catheter can enter the target lung segment or sub-lung segment bronchus through the operation channel of the bronchoscope, the inflated cuff seals the airway cavity around the lung segment bronchus catheter cavity, then the guide wire is pulled out from the lung segment bronchus catheter cavity, the target lung segment or sub-lung segment is inflated through the catheter ventilation and suction interface, so that the anatomical range of the target lung segment or sub-lung segment after ventilation is revealed, the technical problem that a thoracic surgeon cannot accurately identify the anatomical range of the target lung segment in the operation is effectively solved, and the thoracic surgery anatomical partial lobectomy operation is facilitated.
