Abstract

The invention discloses a bronchial navigation model. An application method of the bronchial navigation model comprises the following steps: shooting 1 mm thin chest CT and performing three-dimensional reconstruction; inserting a column into a metal strip of a base; connecting a core wrapping guide wire onto the column and then a splitter onto the core wrapping guide wire; separating a target branch and non-target branch from the splitter; respectively inserting and connecting an analog target bronchial open section ring and a non-target bronchial open section ring onto the target branch and the non-target branch; regulating a navigation model from a secondary bronchus according to CT of a patient to simulate the bronchus path required for reaching a target focus and the opening positions of all bronchi, and changing the direction if necessary; and entering a fiber bronchial microscope for operation according to indication of the navigation model. Compared with blind material taking, the bronchial navigation model can remarkably improve the examination accuracy and the operation efficiency, relieves discomfort caused by long-time operation of the patient or anesthesia side effects, and dispenses with electronic navigation or virtual navigation and other expensive devices and equipment.

Description

technical field [0001] The invention belongs to the field of medical instruments, in particular to a bronchial navigation model. Background technique [0002] The biopsy, brushing, and lavage of lung lesions through bronchoscopy are relatively blind, the accuracy and efficiency of the inspection are low, the operation is cumbersome, and expensive electronic navigation or virtual navigation equipment is required. Contents of the invention [0003] The purpose of the present invention is to provide a bronchial navigation model and its use method, aiming to solve the problem of the existing biopsy, brushing and lavage of pulmonary lesions through bronchoscopy, the blindness of the operation is relatively large, and the inspection is accurate Low performance and low operating efficiency, cumbersome operation, and high inspection costs. [0004] The present invention is achieved in this way, a bronchial navigation model includes a base, a cylinder, a metal strip, a cored guide...
