Medical Insertion Apparatus with Integrated Electrode for Nerve Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current medical insertion apparatuses face challenges in efficiently detecting nerves and preventing neurological damage during surgeries, while also requiring complex procedures and potentially high radiation exposure.
Innovation Solution
A medical insertion apparatus featuring a screw body with a through-hole and an externally exposed electrode, where the electrode is disposed in a central portion of the screw body and extends externally, allowing for nerve detection and guiding the insertion process, and is designed for easy assembly and connection/separation, using biocompatible materials like titanium and platinum for enhanced conductivity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional screw body without integrated electrode is used, then the device structure is simpler, but the nerve detection efficiency is reduced and neurological damage risk increases
Solution Approach 1:
The patent combines the screw body and electrode into a single integrated medical insertion apparatus. The electrode is positioned within the screw body structure, allowing simultaneous mechanical fixation and neurological monitoring functions. This merging eliminates the need for separate electrode insertion procedures and ensures coordinated operation of both components.
Solution Approach 2:
The medical insertion apparatus performs multiple functions: mechanical fixation through the screw body and neurological detection through the integrated electrode. This multi-functional design allows a single device to replace what would traditionally require separate instruments, improving surgical efficiency and nerve detection capability simultaneously.
2Manufacturing precision
If complex insertion procedures are used, then the insertion precision may be improved, but the surgical time and radiation exposure increase
Solution Approach 1:
The electrode is pre-positioned within the screw body structure before surgery. This preliminary arrangement eliminates the need for complex intraoperative electrode placement procedures, reducing surgical time and radiation exposure while maintaining precise insertion capability through the integrated design.
3Strength
If the electrode is fully embedded in the screw body, then the structural integrity is improved, but the electrical conductivity and signal detection capability are reduced
Solution Approach 1:
The electrode is strategically positioned within specific regions of the screw body structure, allowing different parts of the device to serve different functions. The screw body provides mechanical strength while the electrode maintains electrical conductivity for signal detection, achieving local optimization of both properties.
4Stability of the object's composition
If the screw body and electrode are permanently bonded, then the structural stability is improved, but the ease of maintenance and replacement is reduced
Solution Approach 1:
The medical insertion apparatus is designed with separable components - the screw body and electrode can be detached from each other. This segmentation allows the electrode to be replaced or maintained independently while preserving the screw body structure, facilitating easier repair and replacement procedures.
