CUHK recently won the top prize for the first time ever at the 17th National College Students’ Extracurricular Academic Science and Technology Contest (Challenge Cup). The University was the only one in Hong Kong to receive the top and first prizes for its outstanding performance.
Top Prize: Miniaturised Robotic Steerable Surgical Drill for Confined-Space Bone Work
Supervised by Professor Samuel AU Kwok Wai, PhD students WANG Yan, LIN Hongbin, and WANG Xuchen from the Department of Mechanical and Automation Engineering (MAE) developed a miniaturised steerable surgical drill for bone work in a confined space. The tip’s miniature size (4.5 mm in diameter) and large distal bending angle of 65° allow it to target surgical sites through small incisions while steering around anatomical corners – reducing intraoperative damage, shortening hospitalisation and recovery times, and lowering the risk of complications in the process. The team integrated the drill into lightweight and easy-to-use handheld devices for precise yet dexterous surgical operations, along with the option of mounting the devices onto robotic arms for robot-assisted surgeries at a higher level of surgical precision. The surgical robotic system works in a human-robot shared control mode, allowing surgeons to move their surgical tools by dragging the robot-guided arm safely and precisely. Cadaver studies show that the proposed devices have the potential to minimise intraoperative tissue damage in many confined-space surgical procedures, including trans-nasal transsphenoidal pituitary surgeries and transoral mandibular fracture internal fixation surgeries.
