Medical Procedure Video Capture with Pre-Trigger Buffering

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing integrated operating room systems lack the capability to efficiently capture and record fleeting moments during medical procedures for review or training purposes, often resulting in missed critical events due to delayed triggering.

Innovation Solution

The system employs a processor and memory to record video from multiple sources, buffer video segments before a triggering event, and capture a video segment including prepended buffered segments, allowing for efficient capture of events both before and after the trigger.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the system waits for a trigger event to capture video, then storage space is conserved and bandwidth is reduced, but critical moments may be missed due to delayed triggering

Engineering Contradiction:

Improvecapture reliabilityVSAvoidtime delay

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The system performs preliminary actions by continuously buffering video data in memory before a trigger event occurs. This allows the system to have video segments ready for immediate capture and playback when triggered, eliminating the time delay associated with traditional on-demand recording while maintaining reliability for capturing critical moments

Inventive Principle:

Principle #10Preliminary action

2Reliability

If the system buffers video segments before triggering, then critical moments including pre-trigger events are captured, but memory usage increases

Engineering Contradiction:

Improveevent capture completenessVSAvoidmemory usage

Core Design Contradiction:

ReliabilityVSQuantity of substance

Solution Approach 1:

The video stream is segmented into discrete video segments that are buffered in memory. Only the necessary portions (pre-trigger and post-trigger segments) are retained, while other portions are discarded. This segmentation approach ensures complete event capture while managing memory usage by not storing the entire video stream

Inventive Principle:

Principle #1Segmentation

3Loss of information

If the system captures extended video segments, then more context is available for review and training, but data transmission bandwidth increases

Engineering Contradiction:

Improveinformation completenessVSAvoidbandwidth consumption

Core Design Contradiction:

Loss of informationVSLoss of energy

Solution Approach 1:

The system applies partial action by capturing only the specific video segments needed - the buffer segment before triggering and the post-trigger segment - rather than capturing the entire video stream. This provides sufficient context information for review and training while minimizing bandwidth consumption during data transmission

Inventive Principle:

Principle #16Partial or excessive action

AI summary

A system can perform image capture during a medical procedure. The system can record video from one or more video sources. The system can store the recorded video in a cached memory as stored video. The system can receive a triggering event, such as receiving a signal, operation of an actuator, or issuance of a voice command. In response to the triggering event, the system can capture a video segment from the stored video. Because the video segment is captured from stored video, the video segment can optionally include video and/or frames that occurred before the triggering event is received.
