چکیده
|
Realistic simulation of tool-tissue interactions can help to develop more effective surgical training systems and simulators. this study uses a finite element and meshless modeling approach to simulate the grasping procedure of a large intra-abdominal organ, i.e. a kidney, during laparoscopic surgery. results indicate that the accuracy of the meshless method is comparable with that of the finite element method, with root mean square errors in the range of 0.8 to 2.3 mm in different directions. for the model presented in this study, the computational cost of the meshless method was much less than that of the finite element model.
