Abstract
Microsurgeons require dexterity to make precise and stable maneuvers to achieve surgical objectives and to minimize surgical risks during freehand procedures This work presents a novel common path swept source optical coherence tomography based smart micromanipulation aided robotic surgical tool SMART that actively suppresses surgeon hand tremor The tool allows enhanced tool tip stabilization more accurate targeting and the potential to lower surgical risk Freehand performance is compared to smart tool assisted performance and includes assessment of the one dimensional motion tremor in an active microsurgeon s hand Surgeon hand tremor the ability to accurately locate a surgical target and maintain tool tip offset distances were all improved by smart tool assistance
