Endoscope Auxiliary Tool Operating Device With Circular Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing endoscope auxiliary tools lack high operability, limiting the flexibility and efficiency of endoscope operations.
Innovation Solution
An operating device for an endoscope auxiliary tool featuring a first operating member connected to an endoscope, a rotational movement member, an accommodating member, and a second operating member that is movable along a virtual circle, enhancing the operability by allowing precise control and increased movement range of the endoscope's distal end.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional operating device is used, then the structure is simple, but the operability is insufficient
Solution Approach 1:
The operating device is divided into multiple functional components: a first operating member for linear movement, a rotational movement member for rotational control, and a second operating member for enhanced rotational control. This segmentation allows each component to perform its specific function independently, improving overall operability while maintaining manageable structural complexity
Solution Approach 2:
The device incorporates dynamic movement capabilities through the rotational movement member that can rotate around a rotational movement axis, and the second operating member that protrudes from the accommodating member to provide additional degrees of freedom. This dynamic design enables precise control of the endoscope auxiliary tool's distal end, significantly enhancing operability
2Adaptability or versatility
If the movement range is limited, then the device complexity is low, but the flexibility in accessing hard-to-reach areas is reduced
Solution Approach 1:
The operating device adds dimensional freedom by incorporating rotational movement around a rotational movement axis, in addition to linear movement provided by the first operating member. The second operating member further extends this by providing additional rotational control. This multi-dimensional movement capability enables the distal end to access hard-to-reach areas with enhanced flexibility
Solution Approach 2:
The rotational movement member is accommodated within the accommodating member, creating a nested structure where the rotational mechanism is housed within the overall device body. This nesting approach allows complex movement mechanisms to be integrated without proportionally increasing external dimensions or overall complexity

AI summary
An operating device for an endoscope auxiliary tool includes: a first operating member having one end side connected to the endoscope auxiliary tool that is mounted on an insertion part of an endoscope; a rotational movement member that is rotationally movable and that is connected to the other end side of the first operating member; an accommodating member configured to accommodate the rotational movement member; and a second operating member that is provided to protrude from the accommodating member and that is connected to the rotational movement member. A protruding end of the second operating member is configured to be movable along a portion of a circumference of a virtual circle centered on a rotational movement axis of the rotational movement member, and the accommodating member has a grippable region inside the virtual circle.
