RFID Technology
Radio Frequency Identification Technology
serves as the foundation of our system, providing real-time tracking of surgical instruments throughout the procedure.
Counting System
Counting system is at the core of our design. By tracking and counting the surgical instruments at various stages and locations in the operating room, we maximize the prevention of URFO.
Integrated Back Table
Act as the enabler of our system.
It presents the instrument count on the screens in real-time, continuously assisting and reminding the surgical staff to monitor instrument usage throughout the surgical procedure.
Passive RFID technology is the foundation for the later tracking and counting.
Each surgical instrument is fitted with an RFID tag without battery, while a reader is embedded in the back table.
The RFID reader emits radio waves, and when the tagged instruments come into range, the tags are activated by the energy from the reader, then send back their unique identification data, allowing the system to continuously monitor and count instruments in real-time.
Counting system is the most important part in the design.
The most basic logic is that as long as the instrument count outside the patient in the operating room is accurate and correct, the occurrence of URFO incidents can be completely prevented.
The areas where instruments are placed in the operating room are generally divided into the back table, Mayo stand, and dirty area.
Through continuous RFID tracking, we ensure that the instrument count is accurate at every stage when the instruments are outside the patient—from being taken out of storage, through the preparation stage, to after use—thereby guaranteeing no instruments are left inside the patient.

Unintended Retention of Foreign Objects (URFOs)
Surgical materials or equipment unintentionally left in a patient's body after completing the operation, which poses a significant risk to patient safety.
