Capsule Medical Device Magnetic Guidance with Color-Coded Imaging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current capsule medical device guidance systems lack the ability to clearly distinguish between in-vivo images captured by different imaging units during magnetic guidance, making it difficult for operators to accurately target and maneuver the capsule medical device within a subject's organ.
Innovation Solution
A system that includes first and second imaging units with different imaging directions, a permanent magnet, a magnetic guidance device, an operation input unit, a control device, and an image display device that clearly indicates which image is the operation target during magnetic guidance, allowing for precise control of the capsule medical device's location and orientation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple imaging units are used to capture in-vivo images from different directions, then the completeness of anatomical observation is improved, but the difficulty of identifying the operation target image during magnetic guidance increases
Solution Approach 1:
The patent applies color differentiation to distinguish between images from multiple imaging units. Each imaging unit is assigned a specific color (e.g., first imaging unit displays in red, second imaging unit displays in green), allowing operators to quickly identify which image corresponds to which imaging unit and thereby easily locate the operation target image among multiple displayed images.
2Speed
If real-time magnetic guidance is implemented, then the responsiveness of capsule positioning is improved, but the complexity of coordinating multiple imaging units and magnetic control increases
Solution Approach 1:
The patent segments the display interface by separating the display of different imaging units into distinct visual regions with different colors. The first imaging unit's images are displayed in a first region with first color, while the second imaging unit's images are displayed in a second region with second color. This segmentation simplifies the operator's task of coordinating multiple imaging units during real-time magnetic guidance by providing clear visual separation and identification.
3Quantity of substance
If multiple in-vivo images are displayed simultaneously, then the information availability for comprehensive observation is improved, but the ease of operation for targeted magnetic guidance deteriorates
Solution Approach 1:
The patent uses color coding to enhance the ease of operation when multiple images are displayed simultaneously. By assigning distinct colors to different imaging units (e.g., red for first imaging unit, green for second imaging unit), the system maintains comprehensive information availability while making it intuitively easy for operators to identify and select the operation target image based on color recognition rather than searching through unlabeled images.

AI summary
A system for guiding a capsule medical device comprising a magnet from a state in which surface tension of a liquid surface acts on the capsule medical device, the system having: a magnetic guidance device that generates: a reciprocally rotating magnetic field to the magnet at a predetermined frequency around a horizontal axis parallel to the liquid surface; and a guidance magnetic field to the magnet; and a control device that controls the magnetic guidance device to: in a first step, generate the reciprocally rotating magnetic field to the magnet to rotate the capsule medical device to eliminate the effect of the surface tension on the capsule medical device, and in a second step after the first step, generate the guidance magnetic field to the magnet in a direction away from the liquid surface to move the capsule medical device away from the liquid surface.
