“…For instance, Wang et al proposed a mechanical coefficients identification algorithm for MSM‐based vascular model, and they extended their work on how to formulate to get a set of accurate and efficient coefficients in another paper . Patete et al contributed to constructing the MSM‐based model of female breasts . There could be more complicated supplements to be added to the formulation of MSM for realism, such as anisotropic property of soft tissue to take into consideration in the reference by Gao et al Finite element method (FEM), which is based on continuous mechanics, divides the virtual model into plenty of discrete and nonoverlapped primitives to be analysed theoretically.…”

AbstractThe aim of this study is to improve treatment results and SSI prevention by differential usage of the contemporary suture materials and choice of proper suturing technique. To simulate suturing process and compared two suturing techniques, two FE models were developed. Finite-element analysis (FEA) was based on experimental data of contemporary commercial sutures and soft tissue properties. We applied obtained results for abdominal wall closure in rats and compared non-absorbable suture (capron) with absorbable suture (PDS Plus) for chosen technique. Cross-sections were examined by lighting electron microscope. Afterwards, the results of patients’ treatment are also presented. It was shown that running sew was more appropriate for aponeurosis suturing compared to interrupted sew. The optimal parameters of suturing techniques were computed. Single-row running sew by PDS Plus was proved to hold wound edges for 90 days with less inflammatory response compared to other suture in the result of histological analysis. Application of contemporary synthetic absorbable suture materials with antibacterial coating for laparotomic wounds closure and anastomosis decreases local inflammatory reaction and provides the successful tissue regeneration. Application of advanced SSI prophylactics algorithm was shown to decrease risk of post-operative suppurative complications from 14.2 to 1.6 %.

“…O trabalho de Patete et al (2013) objetivou o desenvolvimento e validação de um modelo de deformação tridimensional para a cirurgia de mama auxiliada por computador, extraindo dados de ressonância magnética e gerando um modelo de malhas tetraédricas representando a pele, gordura e glândulas mamárias; e o método de deformação aplicado foi o massa-mola levando em consideração as forças elásticas internas e externas. A metodologia utilizada neste trabalho envolveu a construção do modelo a partir da segmentação de imagens de ressonância magnética usando algoritmo baseado em Fuzzy C-Means com 4…”

ResumoMOREIRA, Hipólito Douglas França. Deformação de tecidos moles para simuladores médicos: uma abordagem sem malha 2016. 56 f. Dissertação (Mestrado em Ciências) -Escola de Artes, Ciências e Humanidades, Universidade de São Paulo, São Paulo, 2015.Esta dissertação de mestrado propõe o estudo e a implementação de um método de deformação usando modelos tridimensionais sem o uso de malhas baseado na técnica Smoothed Particles Hydrodynamics (SPH), que consiste num sistema de resolução de equações diferenciais para aplicação de conceitos físicos para simular deformação de tecidos moles.A opção pelo método sem malha para processo de deformaçãoé apresentado nesta dissertação como alternativa a um dos métodos mais comuns em simulação de deformação de tecidos, o método massa-mola, explorando questões referentes ao uso de recursos computacionais.Para chegada a definição do método foram analisados os temas envolvendo métodos de deformação, modelos baseados em pontos e o SPH como plataformas para alcançar o desenvolvimento do método proposto pela dissertação.Como forma de comprovar as propriedades do método desenvolvido foi realizada a implementação e testes levando em consideração os modelos de deformação e a interação em tempo real num ambiente de simulação que contempla a deformação de uma mama, levando em conta a comparação com o método massa-mola, o uso de recursos do próprio método em função do aumento de detalhe e do uso de objeto com múltiplas propriedades.Palavras-chaves: deformação de tecidos moles, simulação médica, hidrodinâmica de partículas suavizadas. This master thesis proposes a study and implementation of deformation method using tridimensional models without edge composed meshes based on Smoothed Particles Hydrodynamics (SPH) technique, that consists on differential equation solving system to reproduce physical concepts to simulate soft tissue deformation.
