Endoscopic Replay Mode for Simultaneous Live and Recorded Video
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing endoscopic image recording systems lack user-friendly methods for reviewing and analyzing videos recorded during surgical interventions, particularly in advanced imaging modes like fluorescence imaging, which are crucial for assessing tissue perfusion, requiring complex navigation and manual parameter adjustments.
Innovation Solution
An endoscopic image recording system with a replay mode that allows simultaneous display of a previously recorded video and live video, enabling easy switching between imaging modes, optimized recording and playback parameters, and user-friendly input methods like manual, foot switches, or speech inputs for navigating and analyzing the recorded video.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the video is stored in memory and loaded for playback, then the video can be reviewed in detail, but the system requires complex navigation and manual parameter adjustments
Solution Approach 1:
The system automatically switches to replay mode and loads the previously recorded video from memory without requiring manual intervention. The replay mode is activated automatically after recording ends, and the system self-manages the playback process including displaying both the replayed video and live video simultaneously, eliminating the need for complex manual navigation and parameter adjustments.
Solution Approach 2:
The video is pre-stored in the system's memory during the recording phase, allowing for immediate replay without requiring external storage devices or complex file management. The system prepares the video data in advance by buffering it in memory, so that when replay mode is activated, the video is readily available for immediate detailed review.
2Measurement precision
If the replay mode displays only the recorded video, then detailed analysis is possible, but the operator loses overview of the current operation scene
Solution Approach 1:
The system merges the displayed replayed video and the current live video into a single unified display interface. Both video streams are shown simultaneously on the same display device, allowing the operator to conduct detailed analysis of the recorded video while maintaining continuous awareness of the current operation scene. This combining of multiple information sources resolves the contradiction between detailed review and overall awareness.
3Ease of operation
If the system supports multiple input methods for replay control, then user flexibility is improved, but the device complexity increases
Solution Approach 1:
The operating element is designed with multi-functionality to support multiple input methods including manual operation, foot switch control, and speech input recognition. This single universal interface can adapt to different user preferences and surgical situations, providing hand-free operation options when needed while maintaining simplicity through a unified control mechanism that handles all input types through the same underlying system architecture.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Facilitates quick and detailed review of surgical procedures, ensuring thorough tissue perfusion assessment without losing oversight of the operation scene, enhancing user experience and operational efficiency by simplifying navigation and parameter settings.
Implementation Method 1
the tissue/organ is irradiated using excitation light and with the aid of an endoscope, the fluorescence wavelengths generated by the fluorophore in reaction to the excitation are recorded using the endoscope

AI summary
In summary, a simplified approach for user-friendly playback of a video (5) is provided, which was previously recorded using an endoscopic image recording system (1). To offer the user a high level of security in the use of the image recording system (1) and good usage properties at the same time, it is provided that in a replay mode (37), to which the user can change, for example, by a replay user input (22), on the one hand, a currently recorded live video image (6) is visualized using the image recording system (1), and at the same time the user can observe a playback of the previously recorded video (5) on a display device (8) of the system (1).
