Endoscope Length Measurement Mode via Compatibility Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing endoscope systems lack the ability to determine whether a length measurement mode can be executed based on the connection of a compatible endoscope, necessitating the need for a system that can differentiate and enable or disable length measurement modes accordingly.
Innovation Solution
The endoscope system includes a measurement light-emitting unit and a system controller that determines the connection of a length measurement-compatible endoscope, enabling or disabling the length measurement mode based on the presence of this unit, and superimposes a virtual scale on the subject image for accurate length measurement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the system always displays virtual scale for length measurement, then measurement functionality is available, but the system cannot accommodate both measurement-compatible and non-measurement endoscopes
Solution Approach 1:
The system dynamically adjusts its measurement functionality based on the detected endoscope type. When a measurement-compatible endoscope is detected, the system enables virtual scale display and length measurement mode. When a non-measurement endoscope is detected, the system disables these features. This dynamic adaptation resolves the contradiction by making the measurement features conditional rather than fixed.
2Ease of operation
If the system enables length measurement mode for all endoscopes, then measurement function is provided, but incorrect measurements may occur with incompatible endoscopes
Solution Approach 1:
The system performs preliminary detection of the endoscope type before enabling length measurement mode. The processor device checks whether the connected endoscope is measurement-compatible through detection signals or identification mechanisms. Only after confirming compatibility does the system activate the virtual scale display and measurement functions, preventing inaccurate measurements from incompatible devices.
3Measurement precision
If the system adds detection mechanisms for endoscope compatibility, then measurement accuracy is ensured, but system complexity increases
Solution Approach 1:
The system uses an intermediary detection mechanism where the processor device receives identification signals from the endoscope or checks compatibility through intermediate detection steps. This intermediary approach allows the system to verify endoscope type without requiring complex direct analysis of the endoscope's internal structure, thus maintaining measurement precision while limiting the increase in system complexity.

AI summary
There are provided an endoscope system that can determine whether or not a length measurement mode can be executed depending on connection of an endoscope and a method of operating the endoscope system. An endoscope system (10) includes an endoscope (12) and a processor device (14) that includes a system controller (41) formed of an image control processor. The system controller (41) determines whether or not the endoscope (12) is a length measurement-compatible endoscope in a case where the endoscope (12) is connected to the processor device (14), and enables switching of a mode to a length measurement mode in a case where the endoscope (12) is the length measurement-compatible endoscope.
