摘要: In vitreoretinal surgery instruments are inserted through the sclera to perform precise surgical maneuvers inside eyeball, which exceeds typical human capabilities. Robotic assistance can enhance skills of a novice surgeon, provide guidance during tool manipulation based on desired behavior defined by expert surgeons' maneuvers, and consequently improve outcome. This paper presents an experimental study characterizing safe/desired magnitude forces between instrument insertion port as function depth. We explore two types regressions, polynomial sum sines fit, describe observed user our one-user pilot study, variable admittance control scheme be implemented robotically guide other users towards this for safe operation.
