Distal Force Sensing in 3D for Actuated Instruments: Design, Calibration and Force Computation

Unmet NeedRetinal microsurgery requires the careful manipulation of delicate tissues by exerting minute amounts of force which lie below the tactile sensory threshold of surgeons. Thus, motorized instruments with force sensing are needed to perform tasks such as membrane peeling - a process where the fibrous tissue is delaminated off the retina by applying...
