Thoracic cavity operation lung recruitment simulation teaching aid

The utility model provides a thoracic surgery lung recruitment simulation teaching aid, and belongs to the field of medical instruments. The thoracic cavity operation lung recruitment simulation teaching aid comprises a thoracic cavity model, a lung model and a ventilation pipeline. A chest wall opening is formed in the lower part of the side surface of the chest model; an air tap is arranged in the chest wall opening; a through hole is formed in the top of the thoracic cavity model; the lung model is located in an inner cavity of the thoracic cavity model, and holes are formed in the lung model; one end of the ventilation pipeline is connected with the lung model, and the other end of the ventilation pipeline penetrates through the through hole in the thoracic cavity model and is connected with the external environment. According to the utility model, the lung state of a human body before, during and after a thoracic surgery can be simulated, and the process of lung recruitment can be simulated; and the stru
