There are many studies about tissue model for surgical simulation. It is important to construct tissue model for minimally invasive hip joint surgery because muscle is retracted strongly for securing workspace. In conventional studies the mechanical property of muscle tissue is thought as homogeneous inside of tissues. But it is not proper that muscle tissues has heterogeneity. In this study, it is purpose that the proper muscle model is constructed for minimally invasive hip joint surgery. By approximating the result of viscoelasticity examination to three elements, it is found that elastic modulus is different in different places. Indentation test and simulation evaluate for making sure of effectiveness of parameter in viscoelasticity examination. At last, by comparing between heterogeneity and homogeneity models, necessity of heterogeneity model is identified.
