Endoscope Auxiliary Tool Operating Device With Rotational 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 comprising 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 over the bendable body of the endoscope.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional operating device is used for endoscope auxiliary tool, then the device 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 additional degree of freedom. This segmentation allows each component to handle specific movement types, improving overall operability while keeping each individual component relatively simple.
Solution Approach 2:
The patent adds another dimension of control by introducing the rotational movement member that rotates around a rotational movement axis. This adds rotational freedom to the linear movements provided by the first operating member, creating a multi-dimensional control space that significantly improves operability for manipulating the bendable body.
2Adaptability or versatility
If the operating device is made more complex to improve operability, then the flexibility and control are enhanced, but the manufacturing cost increases
Solution Approach 1:
The bendable body itself is constructed using flexible materials and thin-film structures that allow it to be bent and shaped. This flexibility in the distal end part enables the endoscope to adapt to various anatomical structures and recessed areas, providing versatility without requiring an overly complex operating device.
Solution Approach 2:
The operating device is designed with multi-functional capability, where the combination of linear and rotational movements can achieve various manipulation tasks. This universal design allows a single device structure to handle multiple operational requirements, reducing the need for specialized components and thereby controlling manufacturing costs.

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.
