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.

The invention relates to a postoperative anti-regurgitation self-cleaning drainage tube which is suitable for chest drainage after pulmonary lobectomy. In order to solve the problems that a traditional drainage tube depends on gravity to conduct passive drainage, a tube cavity is prone to forming a biological membrane due to sediment to cause blockage and drainage efficiency is insufficient, a plurality of cilia are arranged on the inner wall of a drainage tube body in a surrounding mode in the circumferential direction, the sizes of the cilia are gradually reduced from the root to the top end, and the elasticity modulus is reduced in a gradient mode in the drainage direction; and the vibration device is matched to drive the cilia to swing directionally in the same direction as the drainage direction. According to the design, by simulating the respiratory tract cilia function and utilizing the synergistic effect of cilia structural characteristics and vibration excitation, tube wall sediments are actively and physically stripped, a biological membrane is destroyed to form a foundation, and meanwhile, cilia directionally swings to form drainage auxiliary thrust. According to the application, the occurrence rate of lumen blockage can be obviously reduced, the drainage efficiency is improved, the postoperative pain and medical cost of a patient are reduced, the recovery period is shortened, and the clinical efficient drainage and anti-blockage requirements are met.

The invention discloses a multi-modal score construction method for identifying benign and malignant pulmonary nodules and application of the multi-modal score construction method. The multi-modal score construction method comprises the steps that 1, data are collected, and data sets serve as a training set and a verification set respectively; step 2, preprocessing the collected low-dose spiral CT image; 3, aiming at the preprocessed low-dose spiral CT image, extracting marker features of the pulmonary nodule under imaging; the pulmonary nodule deep learning malignant probability is acquired, and the pulmonary lobe radiomics detection result of the participant is acquired; 4, based on the extracted pulmonary nodule features, constructing a single-mode nodule score, and verifying and evaluating a score identification effect; and step 5, constructing a pulmonary nodule benign and malignant identification multi-mode comprehensive score. According to the method, after the patient completes low-dose spiral CT or provides biological information, the individualized risk score is automatically generated, and the relative risk level in the screening crowd is visually displayed in a risk percentage mode to assist doctors in decision making and grading intervention.

A method for segmenting an anatomical feature into a plurality of parts may include receiving an image of the anatomical feature; segmenting the image into a plurality of parts based on a trained image segmentation neural network, wherein each part of the plurality of parts is assigned a part label; determining a nodule location associated with a nodule within the anatomical feature; assigning the nodule to a part of the plurality of parts in the image based on the nodule location; calculating at least one distance metric between a first point on a boundary of the part and a second point away from the boundary of the part; and generating a distance-coded image based on the distance metric, wherein the distance-coded image indicates a distance from the boundary of the part to points outside the boundary based on a color scheme.
