| Outline of Final Research Achievements |
A new concept of forceps pressure sensing system using a Fabry-perot interferometer with a processed optical fiber attached to a wire part in the forceps of robotic surgery was constructed. This system used an optical fiber with a specially processed tip to convert the wire displacement caused by forceps motion into an optical signal to measure the force sensation. An interferometer was created using a spacer for the interference part that constitutes the displacement sensor, and the interference spectrum due to cavity creation was measured with a spectrometer. Force sensing of forceps was considered to be possible resolution in this system. We also implemented this displacement sensor on the driving wire in the forceps model and measured the minute displacement of the driving wire against the forceps grasping force, and the correlation was confirmed.
