Lung nodule puncture navigation system

Abstract

The invention relates to the technical field of medical equipment, and specifically relates to a lung nodule puncture navigation system. The system comprises a three-dimensional visualization displayunit, a coarse registration unit, a fine registration unit and a navigation tracking unit, the three-dimensional visualization display unit is used for displaying a lung three-dimensional model, a lung nodule three-dimensional model, a thoracic cage three-dimensional model and a skin three-dimensional model of a patient, the coarse registration unit is used for acquiring information of dissectionposition points from a thoracic cage and the thoracic cage three-dimensional model of the patient and performing registration on the information of the two dissection position points, the fine registration unit is used for performing registration on a point cloud model of the patient skin and the skin three-dimensional model, the point cloud model acquires contour information of the body surface skin of the patient in real time through a positioning tool, and the navigation tracking unit comprises an infrared tracking system used for real-time navigation tracking of the position of the positioning tool on the body surface of the patient. According to the system, the damage to people due to arrangement of a spring coil and the radiation damage to people caused by repeated guiding of CT in the conventional method can be avoided.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a pulmonary nodule puncture navigation system. Background technique [0002] Pulmonary nodule is a multi-system multi-organ granulomatous disease of unknown etiology. It often invades the lungs, bilateral hilar lymph nodes, eyes, skin and other organs, and the chest invasion rate is as high as 80% to 90%. [0003] In traditional lung tumor nodule resection surgery, the localization of lung tumor nodules mainly depends on the placement of spring markers under the guidance of preoperative CT, so that the lung segment where the nodules are located can be located during the operation according to the position of the spring markers. Inserting the spring into the human body before will cause additional damage to the human body, and the insertion of the spring needs to be carried out under the repeated guidance of CT, which will also cause the patient to suffer greater radiati...
