Abstract: Surgical instrument tracking systems, methods and devices are described. The system can include tracking devices configured to detect location events. The tracking device can include sensors, circuits, power sources, memories, and radio interface. The tracking devices can automatically determine a location of the tracking device when the tracking device detects a location event. The tracking device can automatically transmit the location and information related to the location event to a data analytics platform. The data analytics platform can allow a user to track multiple surgical instruments and surgical instrument tray in order to accurately determine when surgical instruments should be replaced, and how efficiently the surgical instruments are used.
