Abstract

The embodiment of the invention provides a medical treatment path navigation method and a medical treatment path navigation system. The medical treatment path navigation method comprises the following steps: at the path planning stage, determining a puncture initial point and a puncture target point leading to a lesion area path, and at the path navigation stage, by combining electromagnetic navigation, puncture and balloon dilatation, breaking through a passage leading to the lesion area via pulmonary parenchyma, thus navigating a guide catheter to the lesion area, therefore, the problem that the lesion position having no communicating obvious natural air passage can not be reached is solved, and the guide catheter can be navigated to any lesion area in the lung.

Description

technical field [0001] The present application relates to the field of medical technology, in particular to a medical path navigation method and system. Background technique [0002] The diagnosis and treatment of pulmonary nodules have become more and more important for the early detection and treatment of lung cancer. The conventional method of biopsy of pulmonary nodules is to directly insert a puncture needle into the lung to obtain a biopsy sample by means of percutaneous puncture. This puncture method has the risk of pneumothorax. Studies have shown that the incidence of pneumothorax is 20-40% in percutaneous lung puncture, and pneumothorax is a serious adverse reaction that may be fatal. A safer way is to use bronchoscopy to biopsy pulmonary nodules through the natural airway, which can reduce the risk of adverse reactions. [0003] However, some lesion locations are special, for example, there is no obvious natural airway access, so the bronchoscope cannot reach th...
