Analyse du besoin en assistance robotique dans la chirurgie de l'oreille

Otologic surgery has some specificities compared to others surgeries. The working space is small, with various anatomical structures to, like ossicles or facial nerve. This requires the use of microscope or. The microscope let the surgeon use both hands, but allows only vision. The endoscope leaves only one hand to the surgeon to use his, but provides a "fish-eye" vision. The rise of endoscopy these past few has led to the development of numerous devices for the surgeon: the, first otological robot designed to performed some movements and hold endoscope, or the Endofix Exo. Both devices need the hand of the surgeon to moved. No robotic device allows the endoscope to be directed autonomously the surgeon keeps both hands free to work, just like when he is working a microscope. The objective of our work is to define the specific needs of otological assistance surgery.
