Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing biopsy support methods face challenges in accurately recognizing tissue sampling due to erroneous operation signals, cumbersome sampling determination buttons, and increased costs, leading to potential diagnostic inaccuracies.
Innovation Solution
A biopsy support device and method utilizing an endoscope with an imaging element, featuring a sampling recognition unit that identifies tissue sampling based on captured image data and generates identification information, reducing operator error and costs by relying on image analysis rather than dedicated operation signals or buttons.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If operation signals from sampling instrument are used to recognize tissue sampling, then sampling recognition is enabled, but erroneous recognition occurs due to erroneous operation and additional transmission configuration cost is required
Solution Approach 1:
The patent replaces the mechanical/electrical signal transmission system with an optical system. The endoscope's imaging element captures images to detect sampling events, substituting the need for dedicated operation signal transmission circuits. This reduces device complexity while maintaining or improving recognition reliability through visual confirmation of the sampling act.
Solution Approach 2:
Instead of relying on direct operation signals from the sampling instrument, the system creates a visual copy (image) of the sampling event. The imaging element captures an image that serves as evidence of the sampling action, allowing recognition without direct signal transmission from the sampling instrument's operation mechanisms.
2Reliability
If sampling determination button is used to recognize tissue sampling, then sampling recognition is enabled, but operation becomes cumbersome and additional button cost is involved
Solution Approach 1:
The system makes the sampling instrument self-descriptive by equipping it with an imaging element that automatically captures images during sampling. The instrument itself provides the recognition data through its own imaging capability, eliminating the need for separate determination buttons or external signal transmission, thereby simplifying operation while maintaining reliability.
3Reliability
If dedicated sampling recognition systems are implemented, then sampling recognition capability is provided, but system cost increases
Solution Approach 1:
The patent makes the endoscope multi-functional by enabling it to perform both its primary imaging function and the secondary function of detecting sampling events. The same imaging element used for general endoscopic imaging is also used to capture sampling moments, eliminating the need for dedicated sampling recognition hardware and reducing overall system cost while maintaining recognition accuracy.

AI summary
A biopsy support device that supports an inspection using a living tissue sampled by a sampling instrument which is used by being inserted into an endoscope having an imaging element, the biopsy support device including a processor configured to recognize that the living tissue has been sampled by the sampling instrument on the basis of captured image data obtained by capturing an image using the imaging element; and generate identification information corresponding to the living tissue in a case where the living tissue is recognized to have been sampled.
