Medical Image Recording Apparatus with Dual Processing Sections
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional image recording apparatuses for medical images struggle to balance recording quality and capacity, often requiring low image quality for backup and high image quality for educational purposes, leading to complex operation and inefficient data management.
Innovation Solution
An image recording apparatus with first and second processing sections that encode medical images based on setting information, allowing for simultaneous recording of low and high image quality videos, with the control section determining the recording destination and switching between image quality settings based on operation signals from an electric knife or endoscope, enabling easy switching between backup and educational recording modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If medical images are recorded at high image quality for educational purposes, then image quality is improved, but recording capacity is consumed faster
Solution Approach 1:
The patent segments the recording function into multiple processing sections (first processing section for low quality backup recording, second processing section for high quality educational recording). Each section handles different quality requirements independently, allowing simultaneous operation with different compression ratios and recording destinations, thus resolving the contradiction between image quality and recording capacity consumption
Solution Approach 2:
The patent implements dynamic switching between different recording modes based on operation signals. The control section automatically switches between backup recording and educational recording modes, adjusting image quality and recording parameters in real-time according to the surgical procedure phase, thereby optimizing the balance between image quality and recording capacity utilization
2Quantity of substance
If medical images are recorded at low image quality for backup purposes, then recording capacity is preserved, but image quality deteriorates
Solution Approach 1:
The patent divides the recording system into separate processing sections: the first processing section handles backup recording with lower quality requirements, while the second processing section handles educational recording with higher quality requirements. This segmentation allows each section to optimize for its specific purpose without compromising the other
Solution Approach 2:
The system performs preliminary classification of recording purposes before actual recording occurs. By detecting operation signals (electric knife signals, endoscope operation signals, scene designation signals), the system pre-determines whether the current phase requires backup-quality or educational-quality recording, and switches modes in advance to ensure appropriate image quality is maintained when needed
3Adaptability or versatility
If multiple recording modes are supported for different purposes, then adaptability is improved, but device complexity increases
Solution Approach 1:
The patent merges multiple recording functions into a unified system with parallel processing sections. Both backup recording and educational recording are handled within the same apparatus, sharing common components like the recording medium and control section, while using separate processing paths for quality encoding. This merging reduces overall system complexity compared to having separate dedicated systems
Solution Approach 2:
The control section dynamically manages the switching between different recording modes based on real-time operation signals. The system automatically adjusts encoding parameters, compression ratios, and recording destinations without requiring manual intervention or complex configuration, thereby simplifying operation despite supporting multiple recording modes

AI summary
An image recording apparatus includes a first processing section that encodes an inputted medical image based on setting information and outputs a first encode result, a second processing section that encodes the inputted medical image based on the setting information and outputs a second encode result, a setting section that retains the setting information, and a control section that controls, based on the setting information corresponding to an operation signal generated based on an output signal of an electric knife, an operation signal obtained by an endoscope that generates a medical image, or an operation signal for designating a medical case scene, the first and second processing sections to output at least one of the first and second encode results and determines a recording destination of the first and second encode results based on the setting information corresponding to the operation signal.
