LUNG TISSUE MODEL FOR USE IN PUNCTURE SURGERY EXPERIMENT

摘要

Disclosed is a lung tissue model for use in a puncture surgery experiment, the lung tissue model comprising: a mounting base plate (1) serving as a model base; an optical positioning unit (2) for identifying a marker (21) by means of an optical positioning apparatus, acquiring the position of the model, and providing reference information for three-dimensional registration with CT data; a lung tissue unit (3) for providing a physiological environment of a lung and a tumor target required for the puncture surgery experiment; a breathing simulation unit (4) connected to a balloon embedded in the lung tissue unit via a pipeline and controlling expansion and contraction of the balloon to simulate the deformation of physiological tissue of the lung and the displacement of the tumor target in a breathing process of a patient; and a data acquisition and control unit (5) for controlling the breathing simulation unit (4) to simulate the breathing process of the patient and recording parameters of the induced motion of the bionic lung tissue. The lung tissue model integrates a pulmonary alveoli bionic model, a tumor bionic model, and the optical positioning of a marker, can simulate respiratory motion of a lung on the basis of real data, and is suitable for use in a puncture surgery experiment based on optical positioning navigation.
