    Area of Science:

    • Medical Informatics
    • Surgical Technology
    • Computer Vision

    Background:

    • Modern workflow management in operating rooms (ORs) necessitates integrating legacy medical devices.
    • Extracting device data and usage times is crucial for a cohesive OR environment.
    • Existing methods struggle to retrieve data from older devices, particularly video outputs.

    Purpose of the Study:

    • To develop and evaluate a video-based approach for extracting device information from legacy OR equipment.
    • To enable the integration of older devices into modern workflow management systems.
    • To enhance the understanding of surgical workflows by analyzing video streams.

    Main Methods:

    • A four-level approach was developed: defining regions of interest, capturing video signals, analyzing content (textual and graphical), and structured data storage.
    • The method was prototyped and applied to neurosurgical case videos.
    • Evaluation involved real intervention recordings of intraoperative ultrasound, neuro-navigation, and microscopes.

    Main Results:

    • The video-based approach achieved recognition rates for device usage exceeding 95%.
    • The method successfully extracted relevant patient and device usage information from video streams.
    • Analysis of microscopic video streams provided insights beyond simple device recognition.

    Conclusions:

    • The developed video-based method effectively extracts essential data from legacy medical devices for integrated OR environments.
    • This approach is versatile, applicable across surgical disciplines without device modification.
    • It significantly enhances surgical workflow analysis by leveraging existing video outputs.
