Adjustable Lead Wire Sheathing for Tangle-Free Length Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lead wire management systems in neuromonitoring procedures face challenges such as tangling, limited free length of individual wires, and susceptibility to interference, leading to disconnections and inconvenience during EEG and IONM procedures.
Innovation Solution
An adjustable sheathing system with movable end portions and securing mechanisms, including a non-conductive composite material sheath, allows for adjustable pressure control and encapsulation of lead wires, enabling customizable free length and protection against interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If lead wires are wrapped in a fixed harness sheath secured with heat shrink, then tangling is prevented, but the free length of individual lead wires cannot be adjusted
Solution Approach 1:
The sheath incorporates movable end portions that can slide along the lead wires, transforming the fixed structure into a dynamic one. This allows the sheath to maintain its bundling function while enabling adjustment of the free length of individual lead wires by moving the end portions to different positions.
Solution Approach 2:
The sheath is divided into a body portion and separate movable end portions. This segmentation allows the end portions to be independently positioned and secured at different locations along the lead wires, providing flexibility in adjusting free length while maintaining overall bundling stability.
2Object-affected harmful factors
If all lead wires are enclosed in a single sheath, then protection from interference is improved, but access to individual wires becomes difficult
Solution Approach 1:
The movable end portions can be slid open or detached from the sheath body, allowing temporary access to individual lead wires when needed. After use, the end portions can be returned to enclose the wires, maintaining protection from interference.
Solution Approach 2:
The sheath is designed to pre-enclose all lead wires for protection, while the movable end portions are prepared in advance to be easily displaced or opened when individual wire access is required, balancing protection and accessibility.
3Stability of the object's composition
If the sheath is made rigid to maintain shape, then structural stability is improved, but the securing mechanism cannot adjust pressure on lead wires
Solution Approach 1:
The sheath body is made rigid to maintain overall structural stability, while the end portions incorporate securing mechanisms with adjustable pressure features. This local differentiation allows the sheath to provide both structural support and adaptive securing pressure where needed.
Solution Approach 2:
The securing mechanisms in the end portions allow adjustment of physical parameters such as compression force and positioning location. This enables the rigid sheath to adapt to different lead wire configurations and secure them with appropriate pressure without compromising overall structural integrity.

AI summary
An adjustable sheathing system is provided for securing and protecting medical lead wires, comprising a lead wire bundle with multiple lead wires, connectors, and electrodes. The system includes first and second end portions, each containing a length of the lead wires and incorporating a securing mechanism. A sheath is connected to both the first and second end portions, encasing the lead wires to provide protection and organization. The securing mechanisms within the end portions enable adjustable retention of the lead wires, enhancing stability and reducing strain on the connections. This configuration facilitates secure management of medical lead wires while maintaining flexibility and protection throughout their length.
