Endoscope Raise Base Detachable Rotary Shaft
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing endoscopes face challenges in efficiently attaching and detaching treatment tools, such as puncture needles, from the distal end, which complicates in-vivo treatments and cleaning processes, leading to potential damage and reduced cleaning efficiency.
Innovation Solution
An endoscope design featuring a rotary shaft with a raise base that is detachable and attachable in a specific direction, allowing for easy rotation and removal of treatment tools, facilitated by a wire connection and seal ring for contamination prevention, enabling intuitive attachment and detachment, and facilitating cleaning by allowing the raise base to be removed and replaced.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the raise base is fixed and integrated with the rotary shaft, then the structural stability is improved, but the cleaning efficiency and ease of repair deteriorate
Solution Approach 1:
The raise base is designed as a detachable component that can be separated from the rotary shaft. This segmentation allows the raise base to be removed for cleaning or replacement while leaving the rotary shaft intact, thereby improving cleaning efficiency without compromising the structural stability when the raise base is attached and properly engaged with the rotary shaft.
2Ease of operation
If the raise base is detachable and attachable, then the ease of operation and cleaning efficiency are improved, but the device complexity increases
Solution Approach 1:
The raise base is designed as a detachable component with engagement features that simplify attachment and detachment operations. This segmentation improves ease of operation by allowing quick removal for cleaning or replacement, while the engagement mechanism is designed to be simple and intuitive, minimizing the increase in device complexity.
Solution Approach 2:
The raise base can be designed as a disposable component that is replaced rather than cleaned. This approach significantly improves ease of operation by eliminating complex cleaning procedures, and while it does increase device complexity slightly due to the attachment/detachment mechanism, the simplicity of the replacement process outweighs this increase.
3Ease of operation
If the raise base is made disposable, then the hygiene and ease of operation are improved, but the loss of substance increases
Solution Approach 1:
The raise base is designed as a disposable component made from inexpensive materials that can be easily manufactured and replaced. This approach improves ease of operation by eliminating complex cleaning and sterilization procedures, and while it does result in loss of material, the low cost and simple manufacturing process make this an economically viable solution that prioritizes hygiene and operational simplicity.

AI summary
An endoscope adapted to insert a treatment tool includes: an opening portion from which the treatment tool protrudes, the opening portion being provided on a distal end of the endoscope; a rotary shaft rotatably mounted in the opening portion, a direction of a shaft center being perpendicular to a longitudinal direction of the endoscope; and a raise base that is attachable to the rotary shaft and detachable from the rotary shaft in a predetermined attaching/detaching direction through the opening portion and is capable of rising around the rotary shaft while being attached to the rotary shaft.
