Abstract:

Micro-surgeons rely on excellent motor control to perform critical tasks and may have hand tremor on the order of 50-100 microns. Surgical procedures on the retina require especially precise motor control to achieve surgical objectives and minimize surgical risks. In this talk, I will introduce a bimanual microsurgical platform, SMART (Smart Micromanipulation Aided Robotic-surgical Tool) for effectively reducing the surgeon hand tremors during vitreoretinal surgery. This SMART was achieved by implementing common path, swept source optical coherence tomography (CP SS-OCT) into a prototype surgical tool that effectively cancels undesirable surgeon hand tremor and unintended instrument drift. Bimanual surgical technique enables completion of complex micro-surgical tasks while enhancing ease and safety. The essential advantage is the ability to strategically grasp tissue with one hand while simultaneously dissecting with the other. The bimanual SMART micro-surgical system effectively suppresses asynchronous hand tremor and efficiently assists ambidextrous tasks. It allows precise bimanual dissection of biological tissues with enhanced efficiency as compared to procedures performed with conventional one-handed approaches. Clinical value would include but not be limited to more accurate instrument targeting, novel micron scale tool actions, minimization of surgical risk, novel microsurgical teaching approaches, and enhanced surgeon capabilities.
