Abstract
The aim of this study is the development of the neurosurgical training system with force feedback device based on finite element analysis. Authors implemented several functions necessary for the training system to simulate microscopically-controlled surgery. These were the selection function of the surgical instruments, the zoom function of the operative field and the display function of the reaction force indicator which displays the real time applied force to the cerebellar tissue. Authors implemented the regional detailed model which were three-dimensional surface models of neurovascular systems to the developed training system. In this study, not only visual view of the surgical scene similar to the surgical field but also tactile sensation due to intraoperative interaction between brain tissue and surgical instruments were successfully demonstrated. Our next goal is to implement a three-dimensional finite element model of the neurovascular system in order to perform surgical tasks on the vessels and cranial nerves as microvascular decompression which exist in the root exit zone just after the cerebellar retraction.
