NTUST Applies Mixed Reality Navigation to Improve Hip Joint Implantation Accuracy
National Taiwan University of Science and Technology announced today that traditional artificial hip joint replacement surgery heavily relies on the surgeon's experience. However, existing high-precision navigation equipment or robotic arm systems are expensive. Therefore, Hsieh Yi-cheng led a research team, in collaboration with clinical doctors, to introduce mixed reality technology, hoping to develop a more intuitive and effective surgical assistance solution.

National Taiwan University of Science and Technology (NTUST) announced today in a press release that traditional artificial hip joint replacement surgery heavily relies on the surgeon's empirical judgment. However, existing high-precision navigation equipment or robotic arm systems are prohibitively expensive. In response, Hsieh Yi-cheng led a research team, in collaboration with clinical doctors, to introduce mixed reality technology, with the aim of developing a more intuitive and effective surgical assistance solution.
Hsieh Yi-cheng explained that mixed reality technology allows surgeons to access critical information in real-time within their field of vision during surgery, eliminating the need to frequently look at external monitors. This enables intuitive "eyes-on, hands-on" operation. The system can also instantly display the tilt angle and anteversion angle of the implant, helping to reduce surgical errors, minimize reliance on additional imaging examinations, enhance surgical accuracy, and lower radiation risks.
To ensure the system's design closely aligns with actual medical scenarios, the team observed complete surgical procedures in an operating room. Tsou Cheng-hao, a PhD student in NTUST's Department of Electrical Engineering, noted that observing clinical surgeries allowed for a deeper understanding of the needs and limitations of the medical field, thus enabling adjustments to the system design.
This research also involved collaboration with Dr. Chang Shu-hao, an orthopedic surgeon at Fu Jen Catholic University Hospital, who incorporated clinical experience into the system's development.
Hsieh Yi-cheng stated that the key to interdisciplinary collaboration in biomedical engineering is being "demand-oriented." Clinical doctors provide first-hand needs and suggestions, helping the team accurately grasp practical application scenarios. In the future, the team hopes to secure funding to continuously optimize the system, aiming for Taiwan medical device certification and clinical application. (Editor: Wu Su-jou) 1150413
