Fiber-optic Navigation Technology for Continuum Surgical Robots:Status and Future Perspectives

Continuum robots are gradually being widely used in minimally invasive interventional surgery. The precise navigation and control of continuum robots has become a research hotspot and difficulty in the field of medical imaging and surgical robots. Fiber-optic navigation is regarded as one of the most promising navigation technologies for continuum robots. After more than 40 years of development, great progress has been made in related theories and methods, technology and systems, and clinical trials at home and abroad, which has promoted the clinical application of this technology. However, there are still several problems that limit the application and development of this technology, and it is urgent to explore solutions. To this end, the research and development history of optical fiber navigation technology is sorted out. The main technical types, technical advantages and disadvantages and key core algorithms of fiber-optic navigation are analyzed. The key issues that need to be studied and resolved are pointed out. The future development is discussed considering the high-precision positioning, force tactile feedback, multi-modal image fusion recognition, intelligence and productization etc.
