Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrode apparatuses struggle to accurately and safely enclose the outer wall of tubes in the body without damaging them, particularly during nerve denervation procedures, and lack precise control over the tensile force applied.
Innovation Solution
An electrode apparatus with a shaft, electrode unit, electrode guide, and motor-interlocked driving units that allow for precise control over the electrode's contact with the tube's outer wall, using a combination of motors and springs to regulate tensile force and guide the electrode's movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the electrode unit is directly attached to the outer wall of the tube, then the nerve denervation effect is improved, but the tube may be damaged by external stimuli
Solution Approach 1:
The patent introduces a component including an electrode that acts as an intermediary between the electrode unit and the tube outer wall. This component is brought into close contact with the outer wall through the electrode guide, which guides and controls the contact process. The component serves as a protective mediator that enables effective nerve denervation while preventing direct attachment that could damage the fragile tube structure.
2Productivity
If the component including the electrode is rapidly attached to the outer wall of the tube, then the surgical efficiency is improved, but the accuracy and safety of attachment is reduced
Solution Approach 1:
The patent employs preliminary action through the electrode guide, which is configured to guide the component including the electrode before actual attachment to the tube outer wall. The electrode guide pre-position s and controls the component's approach, ensuring accurate alignment and controlled contact. This preliminary guiding action enables both rapid deployment and precise, safe attachment to the outer wall.
3Stability of the object's composition
If the tensile force of the component including the electrode is increased, then the contact stability with the outer wall is improved, but the risk of tube damage increases
Solution Approach 1:
The patent applies parameter changes by using a spring configured to provide a tensile force to the electrode unit, with the tensile force regulation block enabling dynamic adjustment of this force. The system can finely regulate the tensile force parameter to maintain optimal contact stability between the component and the tube outer wall, while preventing excessive force that could damage the fragile tube structure.
4Reliability
If the electrode unit is brought into close contact with the outer wall of the tube, then the nerve modulation effectiveness is improved, but the tube structure may be compromised
Solution Approach 1:
The patent uses the component including the electrode as an intermediary structure that can be brought into close contact with the tube outer wall. This intermediary component enables effective nerve modulation through controlled contact while protecting the fragile tube structure from direct exposure to external stimuli. The electrode guide controls this contact process to maintain both effectiveness and structural integrity.
