Endoscope Channel Sensing for Safe Instrument Insertion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing digestive organ endoscope systems require slow and time-consuming insertion of endoscope instruments to avoid damaging the digestive organ, as quick insertion can lead to instantaneous protrusion and potential injury.
Innovation Solution
A digestive organ endoscope system equipped with a sensing portion that informs the user whether the tip of the endoscope instrument approaches the tip of the endoscope channel within a certain distance, allowing for quicker insertion while preventing damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the endoscope instrument is inserted quickly to reduce procedure time, then productivity is improved, but the risk of instantaneous protrusion and digestive organ damage increases
Solution Approach 1:
The sensing portion is positioned in advance at a specific location within the endoscope channel to detect the approaching endoscope instrument tip before it reaches the channel tip. This preliminary detection allows the operator to be alerted in advance, enabling controlled insertion while maintaining quick overall procedure time.
Solution Approach 2:
The sensing portion provides real-time feedback to the operator about the position of the endoscope instrument tip relative to the channel tip. This feedback mechanism allows the operator to adjust insertion speed dynamically, preventing instantaneous protrusion while maintaining efficient procedure flow.
2Reliability
If the endoscope instrument is inserted slowly to prevent digestive organ damage, then safety is improved, but procedure time increases
Solution Approach 1:
By positioning the sensing portion in advance within the channel, the system provides early warning of the instrument tip's approach. This allows the operator to maintain steady, controlled insertion speed without needing to slow down progressively, thus preventing damage while minimizing time loss.
Solution Approach 2:
The sensing portion continuously monitors instrument position and provides feedback to the operator. This real-time information allows the operator to insert the instrument at optimal speed - fast enough to reduce procedure time but controlled enough to prevent damage - eliminating the need for unnecessarily slow insertion.
3Reliability
If the position of the endoscope instrument tip is monitored continuously through a monitor to ensure safety, then reliability is improved, but device complexity increases
Solution Approach 1:
The sensing portion is extracted as a separate, simple component within the endoscope channel that detects instrument tip position mechanically or through simple sensing. This separates the detection function from complex monitoring systems, providing reliable position information through a straightforward mechanism.
Solution Approach 2:
The sensing portion acts as an intermediary element between the endoscope instrument and the operator. It translates the complex task of continuous tip position monitoring into a simple detectable signal or tactile feedback, reducing the complexity of the overall monitoring system while maintaining reliability.

AI summary
The present invention provides a digestive organ endoscope system which allows a user to perceive whether or not the tip of an endoscope instrument inserted along a channel approaches the tip of an endoscope channel portion within a certain distance, thereby being capable of quickly inserting the endoscope instrument up to a position close to the tip of the endoscope channel portion, and thus, it is possible to reduce a procedure time and to prevent a digestive organ from being damaged due to instantaneous protrusion of the tip of the endoscope instrument occurring when the endoscope instrument is quickly inserted.
