Detachable Endoscope Elevator Segmented for Cleaning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing endoscope designs with elevators are complicated, making them time-consuming and effort-intensive to clean after endoscopic examinations.
Innovation Solution
An elevator system for endoscopes featuring a lever at the distal tip with a rotating portion, a first elevation portion with a recessed surface, a second elevation portion that protrudes, and a lever connection portion, made from a material with a tensile yield stress of 40 megapascals or more, allowing for easy attachment and detachment for simplified cleaning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the elevator structure is made complicated to improve functionality, then the elevator can perform better functions, but the cleaning time and effort increase
Solution Approach 1:
The elevator is divided into multiple independent portions (first elevation portion, second elevation portion, lever connection portion) that can be detached from the endoscope. This segmentation allows the elevator to maintain complex functionality while enabling easy removal for cleaning, resolving the contradiction between functional complexity and cleaning time.
2Adaptability or versatility
If the elevator structure is made complicated to improve functionality, then the elevator can perform better functions, but the cleaning effort increases
Solution Approach 1:
By segmenting the elevator into detachable portions, the invention allows complex functional capabilities while reducing cleaning effort. Each portion can be independently removed and cleaned, transforming a difficult cleaning task into a simple process despite the elevator's functional complexity.
Solution Approach 2:
The elevator portions are extracted from the endoscope as separate detachable components. This extraction enables the elevator to maintain its functional complexity while allowing easy removal and cleaning, reducing the effort required for maintenance.
3Ease of operation
If the elevator is made detachable for easy cleaning, then cleaning becomes simpler, but the structure becomes more complex
Solution Approach 1:
The elevator is segmented into multiple portions with specific connection structures (lever connection portion, elevation portions). While this creates structural complexity, it enables detachability for easy cleaning. The segmentation principle allows the structure to be more complex internally while maintaining simplicity in operation and cleaning.
