Outline of Final Research Achievements

High level safety is required for a hydraulic active catheter system to support minimally invasive surgery that was expanding its scope of disease in recent years. In this research, the hydraulic active catheter system without electrical leakage even at any accident by integrating an optical bending sensor was constructed. The optical sensor was prototyped, output signal of the prototype sensor was measured and theoretical model of the sensor was constructed. A control system integrated with the hydraulic active catheter system and the sensor was developed.
