| Research Abstract |
In these decade, intraoperative MRI-guided surgeries are performed using real time biological information of the patients. For more precise surgery, a robotic device with navigation is considered useful inside the MRI environment. In this project, we proposed a novel MRI compatible rotation-and-brake actuator for MRI-guided surgical device to achieve precise positioning tasks. The actuator combines a stepping rotation mechanism using pneumatic power and a freezing brake mechanism using peltier cooling element with water. Prototype actuators are developed and evaluated. There is a problem in the response speeds, it is realized that the positioning accuarcy and the strength of the fixing force are enough for the positioning use.
