Abstract:
Objective To explore the establishment of 3D thoracic model by finite element methods,and study the mechanical mechanism of minimally invasive surgery for correcting the chest wall deformity,and provide personalized surgery solution in the future.Methods According to admission and exclusion criteria,we selected 10 cases of pectus carinatum that received chest CT scan.The finite element model of pectus carinatum was established and analyzed by Mimics,ABAQUS,etc.The validity of finite element method for chest wall was verified by comparing the sternal displacement between the simulated values and actual values with the same force.Results The 3D finite element model of pectus carinatum was successfully established and analyzed.The stress distribution of the 10 cases in the posterior ribs was mainly in the 1-6 ribs on both sides,mostly concentrated in the 4th to 6th ribs,and the stress was symmetrical on both sides.Statistical analysis showed that the displacement value of the sternum was correlated,and the validity of the model was verified.Conclusion Mimics,ABAQUS and other finite element modeling and analysis software can effectively establish the thoracic 3D finite element model and mechanical analysis,which can help the further development of personalized minimally invasive surgery for correcting chest wall deformities.
