Retractable Tool Endoscope for Unobstructed Camera Views
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing endoscopes are costly to sterilize, invasive due to large channel diameters, and obstructive tools limit camera visibility and ease of introduction.
Innovation Solution
A retractable tool integrated into the endoscope with a control handle allows for a smaller diameter and easier introduction, eliminating the need for a large channel and providing unobstructed camera views by retracting during insertion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a tool is introduced inside the endoscope channel, then the operation function is enabled, but the channel diameter must be relatively large which increases invasiveness
Solution Approach 1:
The tool is merged with the endoscope by integrating it into the flexible element structure. The tool is formed as an integral part of the flexible element, eliminating the need for a separate large-diameter channel to accommodate a sliding tool, thus reducing invasiveness while maintaining operational capability
Solution Approach 2:
The tool is nested within the flexible element structure rather than requiring a separate channel. The tool can be positioned within the flexible element's construction, allowing it to be deployed from a compact configuration without requiring excessive space during insertion
2Adaptability or versatility
If fixed tools are positioned at the flexible end of the endoscope, then operation capability is provided, but the tools obstruct the camera view and make introduction difficult
Solution Approach 1:
The tool transitions from a fixed position to a retractable configuration. The tool can be retracted into the flexible element or head portion when not in use, clearing the camera's field of view during insertion and imaging phases, then extended when operational capability is needed
Solution Approach 2:
The tool is preliminarily positioned in a retracted state during the introduction phase, ensuring unobstructed camera views and easier insertion. The tool is then deployed to its operational position only when needed at the work area
3Ease of manufacture
If reusable endoscopes are used, then cost is reduced, but complex sterilization is required which takes much time and expensive material
Solution Approach 1:
The endoscope is designed as a single-use disposable device rather than a reusable instrument. This eliminates the need for complex and time-consuming sterilization processes, reduces healthcare facility costs for sterilization equipment and materials, and allows the device to be manufactured from less expensive materials that don't require sterilization-resistant properties
