The objective of this project is to develop a robotic system for in-office laser surgery of the vocal folds. Laryngeal tumors affect approximately 2.5% of the adult population, and office surgery is emerging as a convenient treatment option for these tumors, as opposed to traditional (and more expensive) surgical treatment in the operating room. Unfortunately, not every patient qualifies for office surgery: recent studies indicate that 1 in 3 patients have tumors in locations that physicians cannot reach with the limited instrumentation available in the clinic. To tackle these issues, we explore a new set of needle-thin, highly dexterous robotic instruments, with the overarching goal of amplifying a physician’s reach during office procedures. We articulate our proposed instruments using a concentric agonist-antagonist mechanism, which enables tight bending in a small form factor. We propose a novel intuitive control system and an experimental procedure to verify its ability to reduce the difficulty of completing the in-office procedure. Our experiments verify the mechanical capabilities of the device and demonstrate that our device increases the portion of the voice box accessible to the physician during an endoscopic procedure.
