Step 5, respectively inserting and connecting the simulated target bronchial opening section circle and the non-target bronchial opening section circle on the target branch and the non-target branch;

Step 6. Adjust the navigation model from the second-level bronchus according to the patient's CT, simulate the bronchial path and the position of the bronchial openings at all levels to reach the target lesion, and rotate the direction if necessary;

Step 7. Follow the instructions of the navigation model to enter the fiberoptic bronchoscope for operation.

The present invention is mainly used for path navigation for biopsy, brushing and lavage of pulmonary lesions through bronchoscopy. By analyzing the patient's chest CT and combining this model, it is very convenient to find the target through the simulated bronchial path at all levels. Lesions, the present invention can be divided into 8-9 grades of bronchi, compared with blind sampling, it can significantly improve the accuracy of inspection and the efficiency of operation, reduce the patient's discomfort or side effects of anesthesia caused by long operation time, and does not require electronic navigation or Expensive equipment and equipment such as virtual navigation.

detailed description

In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

The application principle of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

Please refer to Figure 1-Figure 3:

A bronchial navigation model includes a base 1, a cylinder 2, a metal strip 3, a cored guide wire 4, a brancher 5, a target branch 6, a non-target branch 7, a target bronchial section circle 8, and a non-target bronchial section circle 9;

The base 1 includes an upper and lower layer of transparent plexiglass base, the metal strip 3 is installed on the base, and the column 2 is inserted on the metal strip 3;
