A recently granted patent (Publication Number: US11883116B2) discloses a tracker for a surgical navigation system that includes a first switch capable of being operated between two switch configurations. The tracker comprises one or more sources of electromagnetic radiation that can emit radiation with different characteristics based on the switch configuration. The first switch is pre-configured to assume the first configuration and switches to the second configuration only while being operated or for a fixed duration after operation. The radiation characteristics can include different frequencies, wavelengths, and emission patterns, with the ability to selectively control the emission based on the switch configuration.

Furthermore, the patent describes a surgical navigation system incorporating the tracker, an optical sensor for detecting radiation characteristics, and a processor for identifying the switch configuration based on the detected characteristics. The processor can assign different tracking modes to the two switch configurations, enhancing the functionality of the system. Additionally, the optical sensor, which can be a camera, is designed with a frame rate higher than the operation frequencies of the tracker, ensuring accurate detection and tracking. Overall, the patent introduces a novel tracker design and system architecture for surgical navigation, offering improved control and tracking capabilities during medical procedures.
