In the context of robotic surgery, time delays—often referred to as latency—between the surgeon's control console and the operating site are a significant technical hurdle for telesurgery.

These delays interfere with the procedure by creating a disconnect between the surgeon's physical inputs and the real-time response of the robotic instruments. Because surgical precision relies on immediate feedback and fluid coordination, even slight lags can disrupt the surgeon's ability to perform delicate maneuvers safely and accurately. This lack of synchronization was a primary reason why remote surgery failed to gain widespread popularity despite early successful demonstrations like the 2001 Lindbergh Operation.1
