Researchers at Vanderbilt University have developed a continuum robot that achieves multi-scale motion and may allow previously impossible complex microsurgeries. The robot can provide both large macro motion workspace as necessary for surgical intervention, as well as small micro motions workspace with motion resolutions of one micron or less.
The miniaturization and range of motion achieved by this technology would allow precise control during procedures on complex aneurysms, tiny veins and arteries, nerves, and the delicate structures of the eye, the inner ear, and the vocal cords.
Said Vanderbilt researcher Nabil Simaan, "This new class of robots will provide micro-precision while traversing macroscale sinuous pathways to the operation site."
