US Patent 10039474 System for tracking microsurgical instrumentation

An embodiment in accordance with the present invention provides a tracking system architecture for tracking surgical tools in a surgical field. The system architecture is integrated into a mask placed directly on the face of the patient. The system can combine multiple imaging and range finding technologies for tracking the eye and the surgical instrumentation. The system can be used to generate a three dimensional scene for use during the surgical procedure. Additionally, the system can incorporate a modular design to account for variable anatomy. The system described is for eye surgery applications. However, the system could also be used for other procedures such as cochlear implant or craniotomy.
