Abstract: A wearable image display device for surgery includes a display unit, a wireless receiver and a processing core. The wireless receiver wirelessly receives a medical image or a medical instrument information in real-time. The processing core is coupled to the wireless receiver and the display unit for displaying the medical image or the medical instrument information on the display unit.

Abstract: An optical tracking system for a medical equipment includes optical markers, optical sensors and a computing device. The optical markers are disposed on the medical equipment. The optical sensors optically sense the optical markers to respectively generate sensing signals. The computing device is coupled to the optical sensors for receiving the sensing signals, and comprises a surgical situation 3-D model. The computing device is configured to adjust a relative position between a virtual medical equipment object and a virtual surgical target object in the surgical situation 3-D model according to the sensing signals.
