Rotatable Magnetic Coupling for Endoscopic Instrument Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current medical systems for endoscopic procedures face challenges in efficiently coupling secondary medical devices to primary devices, leading to increased user fatigue, prolonged procedure duration, and higher costs due to limited movement and articulation of medical instruments.
Innovation Solution
A coupling device with a first and second portion, featuring magnetic and trapezoidal protrusion arrangements, allows for rotatable and pivotable coupling of medical devices, enabling flexible positioning and reduced user fatigue during procedures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the secondary medical device is coupled to the primary medical device using a fixed connection, then the structural stability is improved, but the movement flexibility and articulation range are reduced
Solution Approach 1:
The coupling device incorporates a rotatable joint mechanism that allows the second medical device to rotate relative to the first medical device around a pivot point. This dynamic connection enables the system to transition from a fixed to a movable state, providing both structural stability when needed and movement flexibility when required, thus resolving the contradiction between stability and adaptability.
2Device complexity
If the secondary medical device is inserted through the primary device, then the device complexity is reduced, but the movement range and user control are limited
Solution Approach 1:
The coupling device is divided into distinct segments: a first portion that couples to the first medical device, a second portion that couples to the second medical device, and a rotatable joint connecting them. This segmentation allows each component to maintain its functional independence while enabling relative movement between them, improving user control without significantly increasing overall device complexity.
3Adaptability or versatility
If multiple endoscopic instruments are used for tissue resection, then the treatment capability is improved, but the user fatigue increases due to limited manipulation range
Solution Approach 1:
The rotatable joint mechanism enables the second medical device to articulate through a range of motion, allowing the user to manipulate multiple instruments with greater freedom. This dynamic capability reduces user fatigue by enabling more natural hand movements and better access to treatment sites, thus maintaining high treatment capability while improving ease of operation.
