Capsule Medical Apparatus Tissue Biopsy Feedback Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current capsule medical apparatuses lack a reliable method to determine the success of tissue obtaining operations and provide real-time feedback to users, leading to inefficiencies and potential failures in obtaining tissues for biopsy.
Innovation Solution
A capsule medical apparatus equipped with a tissue obtaining unit, a detecting unit, and an output unit that transmits successful/unsuccessful information to the outside, allowing for real-time monitoring and repeated attempts until a tissue is successfully obtained.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a capsule medical apparatus performs tissue obtaining operations without real-time feedback, then the device complexity is reduced, but the reliability of tissue acquisition decreases
Solution Approach 1:
The patent implements a feedback mechanism where the control unit receives detection results from the detecting unit and uses this information to determine whether tissue acquisition was successful. The control unit then outputs this determination to the outside, providing real-time feedback on the tissue obtaining operation's success, thereby improving reliability without requiring complex additional hardware
2Loss of time
If the capsule medical apparatus waits for manual confirmation of tissue obtaining, then the ease of operation is improved, but the loss of time increases
Solution Approach 1:
The capsule medical apparatus performs self-service by automatically determining tissue acquisition success through the detecting unit and control unit, and transmitting this information externally without requiring manual intervention. The system autonomously monitors and reports its own operational status, eliminating time delays associated with manual confirmation while maintaining operational simplicity
3Productivity
If the tissue obtaining operation is performed only once, then the ease of operation is improved, but the productivity decreases due to potential failures
Solution Approach 1:
The feedback mechanism enables the control unit to receive detection results and determine whether tissue was successfully obtained. Based on this feedback, the system can decide whether to repeat the tissue obtaining operation, thereby improving productivity by allowing multiple attempts only when necessary, rather than requiring complex automated retry mechanisms

AI summary
A capsule medical apparatus includes a tissue obtaining unit that obtains a tissue from a body site of a subject; a detecting unit that detects a state of the tissue obtaining unit that varies depending on whether the tissue obtaining unit succeeds in obtaining a tissue; an output unit that outputs information representing whether the tissue obtaining unit succeeds in obtaining a tissue; and a control unit that determines whether the tissue obtaining unit succeeds in obtaining a tissue based on the state of the tissue obtaining unit, which is detected by the detecting unit, and causes the output unit to output the information representing whether the tissue obtaining unit succeeds in obtaining a tissue.
