Endoscopic Video Processor Retrospective Clip Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current endoscopic systems face challenges in efficiently documenting and storing images from procedures, leading to large datasets and difficulties in reviewing important moments, which can result in missed clinical events and repeated procedures.
Innovation Solution
The implementation of a video processor that enables retrospective selection and storage of images, allowing medical personnel to selectively record clinically relevant moments without storing entire procedures, thereby reducing file size and improving documentation efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the entire endoscopic procedure is recorded, then complete documentation of all clinical events is achieved, but the file size becomes very large and difficult to review
Solution Approach 1:
The patent segments the continuous endoscopic procedure into discrete, manageable video clips based on clinically relevant events. Each clip captures a specific anatomical location or procedural moment, allowing the system to store only necessary portions rather than the entire procedure, thus reducing overall file size while maintaining documentation completeness.
Solution Approach 2:
The system extracts and isolates only the clinically relevant portions of the endoscopic procedure for permanent storage. By identifying key events such as anatomical landmarks, pathological findings, or procedural milestones, the system extracts these moments as separate video clips, leaving out redundant or less important segments.
2Measurement precision
If high resolution image sensor is used, then image quality is improved, but the file size increases significantly
Solution Approach 1:
Instead of continuously recording at high resolution throughout the entire procedure, the system uses periodic capture at high resolution only when clinically relevant events are detected or anticipated. The image sensor operates at high resolution intermittently rather than continuously, reducing total data volume while maintaining image quality for important moments.
3Productivity
If retrospective selection of images is enabled, then storage efficiency is improved, but the complexity of the recording system increases
Solution Approach 1:
The system performs preliminary buffering of video data in memory before final storage decisions are made. This allows the system to review and select clinically relevant clips after they are captured but before permanent storage, enabling intelligent selection without requiring complex real-time processing during the procedure itself.
4Reliability
If the endoscope is retracted and re-inserted to re-examine locations, then thorough examination is achieved, but the procedure time increases and patient discomfort increases
Solution Approach 1:
The system creates digital copies of examined anatomical locations by storing video clips that capture the visual appearance of each site. These digital records serve as references that can be reviewed later, eliminating the need to physically re-insert and re-examine locations to verify what was previously observed, thus reducing procedure time and patient discomfort.

AI summary
A video processor configured to record images captured by an image sensor of a visualization device and including a processing circuit including volatile memory, non-volatile memory, and a controller; a housing; and a communication interface, wherein the controller is configured to: present with the display a frame selector and frames stored in the image buffer, update the image buffer with the frames, repeatedly receive a first user input responsive to movement the frame selector, cause the display to present at least some of the frames in response to receipt of the first user inputs, receive a second user input responsive to release of the frame selector, and store a retrospective video file in non-volatile memory, the retrospective video file beginning and ending with frames corresponding to the first and second user inputs.
