Design and Comparison of Magnetically-Actuated Dexterous Forceps Instruments for Neuroendoscopy 170 177 IEEE Transactions on Biomedical Engineering (TBME)
Robot assistance is revolutionizing minimally invasive surgical (MIS) techniques. As robot assistance becomes standard in areas such as urology and general surgery, it remains largely absent in neurosurgery. The primary reason is a lack of dexterous wristed tools that are small and compact enough to maneuver within the confines of the brain. In this study, we present a wireless magnetic power transmission that enables the design of unconventional tiny wristed robot tools. By deploying the tools endoscopically within a silicone brain model, we demonstrate the feasibility of these novel devices for future neuroendoscopic robots. read more

Optical Coherence Tomography Guided Robotic Needle Insertion for Deep Anterior Lamellar Keratoplasty 170 177 IEEE Transactions on Biomedical Engineering (TBME)
Deep anterior lamellar keratoplasty (DALK) is a promising form of partial-thickness cornea transplantation, but its popular “big bubble” technique frequently fails due to difficulty controlling a needle insertion into the cornea. We addressed the surgeon challenges that reduce success rates by demonstrating an optical coherence tomography (OCT)-guided, robotically stabilized workstation for manually or automatically performing DALK needle insertions. In a study with cornea fellows, we found that OCT visualization versus the standard stereo microscope was a key enabler in manual attempts and that our automatic robotic method met or exceeded the performance of cornea fellows. read more
