Lung tissue model for puncture operation experiment

Abstract

The invention discloses a lung tissue model for a puncture operation experiment. The modal comprises a mounting chassis, an optical positioning unit, a lung tissue unit, a simulated breathing unit anda data acquisition and control unit; a pulmonary alveolar biomimetic model, a tumor biomimetic model and an optical positioning marker are integrated by the lung tissue model, so respiratory movementof the lung can be simulated on the basis of real data; the lung tissue model is particularly suitable for puncture operation experiments based on optical positioning navigation, and the real environment is greatly restored.

Description

technical field [0001] The invention relates to the field of medical experiments, in particular to a lung tissue model used for puncture operation experiments. Background technique [0002] As the most common primary lung tumor, lung cancer is the malignant tumor with the fastest increasing morbidity and mortality worldwide and the highest threat to human health and life. Percutaneous lung biopsy can be used to diagnose lung cancer and other lung diseases. At the same time, various tumor ablation techniques based on puncture surgery (such as microwave ablation, radiofrequency ablation, argon-helium knife, etc.) and radioactive particle implantation are newly developed in recent years. minimally invasive tumor therapy techniques. Therefore, lung puncture surgery is of great significance to the detection and treatment of lung tumors. [0003] However, due to the respiratory characteristics of the lungs, the tumor target is constantly moving during puncture, which causes grea...
