Embodiment Construction

[0031] Embodiments of the present invention will be described in detail below. It should be emphasized that the following description is only exemplary and not intended to limit the scope of the invention and its application.

[0032] refer to figure 1 , the construction method of the biomechanical simulation model of the patient with cleft lip and palate includes:

[0033] S100, reconstructing the three-dimensional data model;

[0034] The model refers to the model of the skull. The three-dimensional data model of the skull in this step comes from CTScan (Computed Tomography Scan, computerized tomography scan) data, and can also be obtained from other ways according to the actual situation. Considering the feasibility and rapidity of engineering calculations, the unit size of the skull reconstruction model is usually greater than 2mm. Refactored Model Reference figure 1 . Then the reconstructed data model is divided into grids. The grid adopts a tetrahedron model. The te...

Abstract

The invention provides a construction method of a biomechanical simulation model of a cleft lip and palate patient. The method comprises the following steps: reconstructing a three-dimensional data model; Optimizing the reconstructed model so as to carry out biomechanical analysis; Establishing a bone material model based on human body bone material characteristics; And a mechanical environment ofcleft lip and palate is established. The method has universal applicability and clinical popularization, main influence factors of the postoperative rehabilitation effect of the cleft lip and palatepatient can be further mined based on the result, theoretical and data support is provided for evaluation of the postoperative rehabilitation effect of the patient and formulation of a next operationscheme, and the medical cost can be saved.

Description

technical field [0001] The invention relates to the field of computer simulation, in particular to a method for constructing a biomechanical simulation model of a patient with cleft lip and palate. Background technique [0002] Cleft lip and palate is one of the most common congenital deformities. It not only affects the child's appearance, but also affects the child's psychological development in future interpersonal communication. There are various surgical methods for cleft lip and palate, but it takes a long time to verify the surgical effect, and it is difficult to have a unified evaluation standard in the short term. In addition, due to differences in the understanding and technical level of different doctors on the principles of surgery, many cases of postoperative deformities also appeared. For these practical clinical problems, the best solution is to combine computer-aided and 3D medical imaging. However, there is currently a lack of advanced three-dimensional vo...
