Endoscope Mounting Mechanism for One-Person Operation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mother-baby endoscope systems face challenges in operability and instrument insertion efficiency, particularly when using a baby endoscope with a baby endoscope system, requiring complex hand movements and additional accessories for mounting, which can decrease usability and increase the difficulty of performing medical procedures.
Innovation Solution
A medical device and endoscope system design that includes a first endoscope with a bending operation member and a detachable second operation portion, allowing for improved operability by simplifying the mounting process and reducing the need for external accessories, with a concave portion on the baby endoscope to fit the mother endoscope's braking finger grip, enabling one-person operation and enhanced instrument insertion without looping.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a baby endoscope is inserted into a treatment instrument insertion channel of a mother endoscope using conventional mounting methods (strap and looping), then the baby endoscope can be secured to the mother endoscope, but the operability decreases and hand movements become more complex
Solution Approach 1:
The mounting structure is divided into separate components: a mounting portion with a concave portion on the baby endoscope and a corresponding凸起 portion on the mother endoscope. This segmentation allows for easier attachment and detachment while maintaining secure mounting, resolving the contradiction between mounting stability and ease of operation.
Solution Approach 2:
The complex looping and strapping methods are replaced by a simplified mounting mechanism where the baby endoscope is directly attached to the mother endoscope through complementary mounting portions. This extraction of unnecessary mounting steps improves operability while maintaining secure attachment.
2Reliability
If additional accessories (strap and looping) are used to mount the baby endoscope, then the mounting stability is achieved, but the device complexity increases
Solution Approach 1:
The mounting function is merged into the endoscope structures themselves through the mounting portion and凸起 portion design. This integration eliminates the need for separate straps and looping accessories, reducing device complexity while maintaining mounting stability.
Solution Approach 2:
The endoscopes are designed with self-mounting capabilities through their mounting portions. The baby endoscope can be directly attached to the mother endoscope without requiring external accessories, simplifying the overall system while ensuring stable mounting.
3Ease of manufacture
If the baby endoscope operation portion is mounted on the distal end side of the mother endoscope, then the insertion is simplified, but the hand movement complexity increases reducing usability
Solution Approach 1:
The mounting position of the baby endoscope is made adjustable along the mother endoscope rather than being fixed at the distal end. This dynamic positioning allows optimization of both insertion simplicity and operational usability, resolving the contradiction between the two parameters.

AI summary
A medical device includes an operation portion, an insertion portion that is insertable into a treatment instrument insertion channel of a mother endoscope, and a mounting portion provided at an operation portion to detachably mount the operation portion onto a bending operation member of the mother endoscope.
