Surgical Video Extract Generation via Marker-Based Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for monitoring physiological parameters during surgical operations or diagnostic investigations do not allow for the simultaneous evaluation of multiple parameters from different instruments, nor do they facilitate the extraction of significant phases of a video recording in real time.
Innovation Solution
A method for generating an extract of significant steps from video footage of a surgical operation or diagnostic investigation, involving the definition of markers representing significant passages, identification of marker pairs, duplication and recording of video segments between markers, and merging these segments into a single extract file.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If all video footage from surgical operations is stored in full, then complete documentation is achieved, but storage space and post-processing time are excessively consumed
Solution Approach 1:
The patent extracts only the significant portions of video footage by detecting keyframes that represent critical surgical events. Instead of storing and processing all video data, the system identifies and extracts only the essential segments marked by keyframes, thereby reducing storage requirements and post-processing time while maintaining complete documentation of important surgical moments
Solution Approach 2:
The system performs preliminary detection and marking of keyframes during the surgical operation itself. By identifying and tagging significant moments in real-time or near-real-time, the system prepares the video data in advance, so that when post-processing is needed, only pre-identified segments require detailed analysis, significantly reducing the time and computational resources needed later
2Reliability
If multiple instruments and equipment are monitored simultaneously, then comprehensive patient monitoring is achieved, but system complexity and data integration difficulty increase
Solution Approach 1:
The patent merges data from multiple surgical instruments and equipment into a unified video feed by overlaying graphical representations of physiological parameters directly onto the video footage. This integration approach combines multiple data streams into a single composite view, allowing comprehensive monitoring of patient condition while simplifying the user interface and reducing the complexity of managing separate displays for each instrument
Solution Approach 2:
The system creates a multi-functional video recording that simultaneously serves as both a visual documentation of the surgical procedure and an integrated physiological monitoring record. By embedding parameter data within the video stream itself, the system enables a single medium to fulfill multiple functions: surgical documentation, patient monitoring, and event correlation, thereby reducing overall system complexity

AI summary
A method for generating an extract of significant steps of a video footage representative of the performance of a surgical operation or complex diagnostic investigation is produced by a medical recorder 100 and displayed on its monitor. And includes:the definition of a set of markers provided in the video footage, and representative of the beginning and end of significant passages thereof;the identification, in said video footage, of one or more pairs of said markers, each of said pairs being constituted by an initial marker and a final marker defining portions;merging all the recorded portions of the video footage in order to obtain, on the computer medium, a significant extract of the whole video footage.
