| The repairing of cleft lip affects the patient's face; it leads to less and less opportunity for the interns and grassroots physicians to practice, so it's hard for them to mater the repair technique in a short time. In the traditional surgery of cleft lip, most doctors make preoperative simulation in the brain to determine surgical plan, then do operation according to the formed 3d (three-dimensional) impression. In addition, the repairing of cleft lip is abstract and complicated. Therefore, it's urgent to build a virtual repair platform for cleft lip which is dynamic, can simulate the procedure and forecast the effect of surgery.Moreover, how much the stress generated by the surgery of cleft lip and the stress difference between different repair methods, they are concerned with the formation of scar and the comfort of the patient's wound site, the research can also help doctors to make better surgical plan, then to take treatment.At first, the text is to build website platform in repairing cleft lip which combined computer technique and clinical repair technique of cleft lip. The website platform includes 3d virtual repair animation of cleft lip which is made by 3dmax software, 2d (two dimensional) virtual repair animation based on FLASH software, and the database of patients'information, the relevant professional knowledge about cleft lip etc.In addition, the text is to analyze the stress situation at the time of repairing cleft lip. The partial model of cleft lip is built in SolidWorks software, then the harelip forms after cutting are constructed based on the methods of low triangular flap and revolving propulsion; The model is imported into ANSYS Workbench software to get the figures about total formation and stress distribution after meshing, defining material under the method of linear elastic model, determining the boundary condition and loading. |
