Endoscope Insertion Tool Diameter Enlarging Structure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional endoscope apparatuses face difficulties in extracting the insertion section with a balloon from an insertion assisting tool due to the balloon being caught by the tool's tip end, leading to challenges in removing the endoscope from the body cavity.
Innovation Solution
The endoscope apparatus incorporates a diameter enlarging structure at the tip end of the insertion assisting tool, which can be enlarged using soft materials like rubber or sponge, notches, or an inclined surface, allowing the balloon to be easily extracted by preventing entanglement and allowing the balloon to protrude and be removed from the tool.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If the tip end of the insertion assisting tool is formed into a throttled shape to prevent intestinal wall entanglement, then the intestinal wall is protected from pinching, but the balloon of the endoscope insertion section is caught by the tip end part, making extraction difficult
Solution Approach 1:
The tip end part of the insertion assisting tool is designed with a diameter enlarging structure that can dynamically change its diameter. During insertion, the tip end maintains a smaller diameter to prevent intestinal wall entanglement. During extraction, the diameter is enlarged to allow the balloon to pass through smoothly, thus resolving the contradiction between preventing entanglement and enabling easy extraction
Solution Approach 2:
The diameter of the tip end part of the insertion assisting tool is changed as a parameter. The tip end part is constructed with materials or structures (such as soft members, expandable structures, or segmented designs) that allow the diameter to be enlarged during the extraction phase, enabling the balloon to pass through the tip end part without being caught, while maintaining a smaller diameter during insertion to prevent intestinal wall entanglement
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution enables the easy extraction of the endoscope insertion section with a balloon from the insertion assisting tool, facilitating the removal process without damaging the intestinal wall or causing pinching, thereby improving the operational efficiency of the endoscope apparatus.
Implementation Method 1
the tip end part of the insertion assisting tool is constructed to have a diameter enlarging structure capable of being enlarged in diameter... by constructing the tip end part of the insertion assisting tool by a soft member... a soft member such as rubber, sponge or the like is used for the material of only the throttled portion of the tip end part
