摘要：

Surgeons performing robotic-assisted surgical tasks need to establish the density and constituency of hidden tissue structures using only surgical tools. This is possible by integrating a miniaturized sensor into the end-effectors of robotic surgical systems. In this present work, optical microsystems technology is utilized to develop a miniature force-distribution sensor that can be integrated into surgical end-effectors. The sensing principle of the sensor is based on the mechanism of splice coupling. Since the device is fully optical, the sensor is magnetic-resonance compatible and is also electrically passive. The experimental results performed on the developed sensor confirm its ability to measure the distributed force information. Such information is used to detect different tissue structures such as lumps, arteries, or ureters during robotic-assisted surgical tasks.
