| Outline of Final Research Achievements |
In neurosurgery, in order to secure an operating field, a brain fissure is retracted by surgical tools. Therefore, effects of deformation of soft tissue should be considered to avoid damaging brain tissues. The goal of this study is to develop an automatic path planner considering the deformation of brain tissues. This paper shows a scheme which combines FEM (Finite Element Method) and an optimization method for optimization of retraction in order to approach a deep part of a brain with a spatula. In this scheme, Pattern Search and Genetic Algorithm are implemented as a global optimization method. The FE model of a human brain used in FEM is based on simplified mechanical structure and properties of an actual human brain. This scheme enabled computing optimal posture and position of the spatula.
