Since introducing a robot-assisted microsurgery system in June 2025, the Li Ka Shing Faculty of Medicine at the University of Hong Kong has completed 48 microsurgical procedures without any reported complications. The advanced robotic technology allows surgeons to perform highly precise operations on tissues as small as 0.1 millimeters, addressing challenges posed by hand tremors and physical fatigue during complex surgeries.

The system is equipped with robotic arms that offer seven degrees of freedom, enabling surgeons to navigate and operate within extremely confined anatomical spaces. This capability is particularly advantageous for delicate microsurgeries where manual precision is limited by human physiological factors.

In a landmark achievement last year, the medical team used the robotic system to conduct the world’s first robot-assisted microsurgical reconstruction on a patient with head and neck cancer. This case demonstrated the potential of robotic assistance to enhance surgical accuracy and patient outcomes in complex oncological procedures.

The deployment of this robot marks a significant step forward in microsurgical techniques at the University of Hong Kong, with ongoing evaluation of its benefits in improving surgical precision and reducing complication rates.
