Precise light-dose delivery is essential for photodynamic therapy (PDT), yet current handheld systems remain operator-dependent and lose accuracy under motion. We present a SLAM-guided, closed-loop control framework that enables co-temporal and co-spatial photodynamic diagnosis (PDD) and PDT with a …
In this study, we present a visual servo control framework for fully automated nasopharyngeal swab robots. The proposed framework incorporates a deep learning-based nostril detection with a cascade approach to reliably identify the nostrils with high accuracy in real time. In addition, a partitioned…
This paper presents the design and control of a fully handheld robot for robot-assisted microsurgery. The handheld robot incorporates a miniature 6-PUS parallel micromanipulator that can impose a remote center of motion (RCM) at the incision point of entry during microsurgery. An optimization framew…
We develop a surgical forceps-driver and a haptic feedback master device that could be applied to a tele-operated microsurgical robotic system for peripheral nerve surgery. Considering that the neurological damage could occur to the peripheral nerve when an excessive force is applied to the nerve ti
We develop a miniature suction-gripper with the goal to realize the novel robotic surgical instrument that can grip slippery and flexible peripheral nerves. In developing the instrument, we place a priority on devising the method that can robustly grip the nerve bundles during the surgical operation…
In this paper we describe work towards retinal vessel cannulation using an actively stabilized handheld robot, guided by monocular vision. We employ a previously developed monocular camera based surface reconstruction method using automated laser beam scanning over the retina. We use the reconstruct…
