About

Makoto Ohbu is a leading researcher in the field of robot-assisted surgery, with a primary focus on haptic feedback systems and tissue safety. His most-cited work, "In vivo evaluation of tissue damage from varying grasping forces using the Saroa surgical system" (2025, 7 citations), represents a critical advance in understanding how robotic surgical tools interact with living tissue. Ohbu’s research addresses a fundamental challenge in minimally invasive surgery: the loss of tactile sensation that can lead to unintended tissue trauma. By systematically evaluating grasping forces with the Saroa system—a platform uniquely equipped with haptic feedback—he has provided empirical evidence linking specific force thresholds to tissue damage. This work has immediate implications for surgical training and instrument design, offering a data-driven path toward safer robotic procedures. Ohbu’s contributions are particularly notable for bridging the gap between engineering and clinical practice, ensuring that technological innovation translates directly into improved patient outcomes. His findings are already influencing the development of next-generation surgical robots, positioning him as a key voice in the ongoing effort to make robotic surgery both more precise and more forgiving.
