The present invention discloses a multifunctional medical thoracic wall reconstructor, which includes a rib expander, a thoracic cavity protection sheet and a buckle. The rib expander is implanted between two ribs to expand the distance between the two ribs, and the rib expander is fixed on the ribs by a holding claw. Then, the thoracic cavity protection sheet is implanted between the two rib expanders to protect the thoracic cavity and fix the relative position between the two rib expanders. Both the rib expander and the thoracic cavity protection sheet have different specifications to meet the needs of different patients. This device is simple and practical, which can effectively expand the thoracic cavity of the lung transplantation recipient to adapt to the size of the donor lung, and increase the lung function of the recipient patient and avoid cutting the donor lung. At the same time, the implant has sufficient hardness and toughness, and has good biocompatibility.

The invention provides a method for predicting human lung injury under the action of shock waves, and relates to the technical field of data processing. The method comprises the following steps: constructing an explosion flow field model; constructing an explosion propagation model based on air propagation; the method comprises the following steps: simplifying the chest of a human body into a multi-layer composite medium containing muscles, chest walls and lungs in the front-back direction and the left-right direction, enabling the muscles to be equivalent to a spring damping unit, enabling the chest walls to be equivalent to a mass unit, enabling the lungs to be equivalent to a spring damping unit of a viscoelastic porous structure, and constructing a chest wall speed response dynamic model; determining shock wave pressure when explosion is transmitted to the human body; according to the chest wall speed response kinetic model and the Newton second law, constructing a chest wall speed response motion equation set; the determined shock wave pressure generated when the explosion is transmitted to the human body is substituted into a chest wall speed response motion equation set, the chest wall speed response motion equation set is solved, and chest wall displacement under the action of shock waves is determined; and predicting the lung injury of the human body according to the chest wall displacement.
