Disposable Endoscope Plug Body With Destructible Locking Frame
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing endoscope plug bodies, particularly disposable types, lack a reliable and user-friendly mechanism for secure attachment and easy removal from the endoscope channel opening while maintaining air-tightness, which can lead to leakage and contamination issues during medical procedures.
Innovation Solution
The endoscope plug body comprises a cylindrical plug frame with lock and destruction means, featuring V-shaped grooves and a projection portion for secure fitting and easy destruction, along with an elastic plug member and lid member for air-tight sealing, allowing for secure attachment and removal without compromising the seal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a disposable plug body is used to prevent contamination and ensure air-tightness, then reliability is improved, but device complexity increases due to the need for secure attachment and destruction mechanisms
Solution Approach 1:
The plug body is divided into separate functional components: a plug frame for attachment, a lid member for sealing the channel opening, and a plug member for blocking the insertion channel. This segmentation allows each component to be optimized for its specific function while maintaining overall simplicity
Solution Approach 2:
The plug body is pre-assembled with the lid member and plug member in their correct positions before being attached to the endoscope. The lock means is pre-configured to engage with the base, ensuring that air-tight sealing is achieved immediately upon attachment without requiring additional sealing steps
2Reliability
If a secure lock mechanism is provided to ensure air-tight attachment, then reliability is improved, but ease of operation deteriorates due to difficulty in removal
Solution Approach 1:
The material properties of the plug frame are specifically selected to allow it to be locked securely during use but destroyed easily when needed. The frame is made of a material that maintains structural integrity for reliable attachment but can be broken by simple manual force or scissors, transforming the state from locked to removed
Solution Approach 2:
The plug body is designed as a disposable component where the plug frame can be easily destroyed after use. This allows the secure lock mechanism to function reliably during the procedure while enabling simple removal by destroying the frame rather than unlocking it, improving ease of operation
3Ease of operation
If the plug body is designed for easy removal by destruction, then ease of operation is improved, but reliability deteriorates due to potential leakage during the destruction process
Solution Approach 1:
The separation of the lid member from the plug frame allows the destruction operation to occur on the frame only, after the lid member has already established the air-tight seal. This ensures that reliability is maintained during the removal process as the sealing component remains intact while the frame is destroyed
Solution Approach 2:
The lid member is attached and seals the channel opening before the plug frame is destroyed. This preliminary sealing action ensures that air-tightness is established prior to any destruction operations, preventing leakage during the removal process
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
The solution ensures air-tight sealing during medical procedures and facilitates easy and hygienic removal of the plug body, preventing contamination and reuse errors, while maintaining the plug body's structural integrity for efficient operation.
Implementation Method 1
The plug member is a body separate from the plug frame, formed of an elastic member and has a plug-member treatment instrument insertion portion through which the treatment instrument for an endoscope to be introduced into the pipe line is inserted

AI summary
An endoscope plug body comprises a plug frame, a lid member and a plug member and shuts off an inside of a treatment instrument insertion channel from an outside. The plug frame is provided with annular projection portions, a plug body destruction portion and a plug-frame destruction operation portion. A flange portion is arranged between the annular plug portions and fitted to a base of the endoscope. The plug body destruction portion and the plug-frame destruction operation portion releases the lock state by destruction. The plug frame is cylindrical and communicates with a pipe line disposed inside the endoscope. The lid member is separate from the plug frame and has a lid portion disposed at an opening at the other end of the plug frame. The plug member is separate from the plug frame, formed of an elastic member and has a plug-member treatment instrument insertion portion.
