Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems lack effective methods for analyzing and presenting videos of surgical procedures, particularly in identifying key intraoperative events and their properties, which hinders comprehensive documentation and learning from surgical practices.
Innovation Solution
A system that captures and analyzes videos of surgical procedures, identifies key intraoperative events, and presents their properties to users, allowing for the selection of specific events within the video for detailed review, utilizing a combination of image and audio sensors, processing units, and cloud platforms for data storage and communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If video documentation of surgical procedures is obtained and analyzed to identify key intraoperative events, then the completeness of surgical documentation is improved, but the complexity of the system increases
Solution Approach 1:
The surgical video is segmented into discrete key intraoperative events using automated detection algorithms. The system divides the continuous video stream into meaningful segments based on detected surgical events, allowing comprehensive documentation without requiring manual review of entire procedures.
Solution Approach 2:
An automated event detection system acts as an intermediary between the raw video data and the final documentation. This intermediary layer processes video frames and audio signals to identify key events, reducing the complexity burden on users while maintaining documentation completeness.
2Measurement precision
If properties of key intraoperative events are extracted and presented to users, then the quality of surgical analysis is improved, but the processing time increases
Solution Approach 1:
The system performs preliminary processing of video and audio data during the surgical procedure itself, extracting and storing event properties as they occur. This preliminary action allows for rapid retrieval and analysis of surgical events without requiring extensive post-processing time.
Solution Approach 2:
Manual analysis of surgical videos is replaced with automated computer vision and audio processing algorithms. These computational systems rapidly extract event properties from video frames and audio signals, providing high-quality analysis without the time investment required for manual review.
3Adaptability or versatility
If multiple key intraoperative events are identified and stored with their properties, then the value for surgical training and assessment is improved, but the data storage requirements increase
Solution Approach 1:
The system extracts only the essential properties and characteristics of key intraoperative events rather than storing complete video segments. By taking out only the critical event data, timestamps, and relevant properties, the system maintains high training value while reducing storage requirements.
Solution Approach 2:
The system transforms raw video and audio data into structured event parameters and metadata. By changing the data representation from continuous media to discrete event parameters, the system enables versatile surgical training applications with significantly reduced storage requirements.

AI summary
Systems and methods for analysis and presentation of videos of surgical procedures are provided. For example, a video of a surgical procedure may be obtained, time points corresponding to key intraoperative events may be obtained, and properties of the key intraoperative events may be obtained. Further, the properties of the key intraoperative events may be presented to a user, and a selection of a selected intraoperative event may be received from the user. In response, part of the video associated with the time point corresponding to the selected intraoperative event may be presented.
