Selectively Actuated Fiberbots for High-precision Minimally Invasive Surgery
Selectively Actuated Fiberbots for High-precision Minimally Invasive Surgery
This paper presents an electrothermally actuated fiber-based robot designed for minimally invasive surgery (MIS). The robot uses Joule heating in a distal active segment to achieve precise manipulation, with a diameter of 1.9 mm and length of 1.2 m. It can operate independently within endoscopic systems, offering potential improvements in surgical precision.

w independent motion. A phantom demonstration combining the robotic fiber with a da Vinci instrument conceptually demonstrated its compatibility with existing endoscopic systems for clinical applications. Our robotic fiber enables precise distal motion and holds the potential to improve clinical outcomes by enhancing precision in MIS procedures.
