Abstract—This paper presents the development of an insertion simulation of colonoscopes with different diameters inside colon models using ANSYS LS-DYNA. The purpose is to provide insight on the performance efficiency of small-caliber (SC) colonoscopes in reducing patient pain during a colonoscopy considering the effect of gender. In developing such a simulation, the structural differences between the female and male human colons were firstly analyzed and further used as the basis of establishing colon models. The colonic tissue was comprised of a three-parameter Mooney Rivlin model whose parameters were obtained through an optimization procedure with the use of ANSYS and Optislang programs. Colon deformation induced by colonoscopes during the insertion simulation were investigated to provide prediction of patient pain. The simulation results show that colonoscopes with smaller diameters may be helpful in reducing patient pain for females while having no or less advantage for males.
