Sterile Nerve Stimulation Probe With In-Field Monitoring Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing nerve monitoring systems require a monitor user to provide instructions remotely, which can be inconvenient for a procedure user, and the monitoring systems are often not immediately available for placement in a sterile field during procedures.
Innovation Solution
A nerve stimulation probe with integrated switches that allow a procedure user to operate the nerve monitoring system directly, including a control module and sterile switches for in-field control, connected via conductive materials like copper or aluminum wire, enabling direct interaction with the monitoring system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a monitor user operates the nerve monitoring system remotely, then the monitoring system can be controlled from a distance, but the procedure user experiences inconvenience and reduced operational efficiency
Solution Approach 1:
The system is divided into separate functional modules: a sterile field controller with switches for procedure user access, a monitoring system for data processing, and conductive material for signal transmission. This segmentation allows the procedure user to control only the necessary functions directly at the sterile field without managing the entire complex system.
Solution Approach 2:
Conductive material serves as an intermediary component that transmits control signals from the sterile field controller to the monitoring system. This intermediary enables communication between the procedure user's controls and the remote monitoring system without requiring direct connection or complex integration.
2Adaptability or versatility
If the monitoring system is placed remotely from the sterile field, then it can operate independently, but it is not immediately available for placement in the sterile field during procedures
Solution Approach 1:
The system configuration is made dynamic, allowing the monitoring system to be placed either remotely or within the sterile field based on procedural needs. The sterile field controller with integrated switches enables the system to adapt its physical arrangement without losing functionality, reducing deployment time when immediate sterile field access is required.
3Ease of operation
If switches are connected adjacent to the surgeon, then direct control is enabled, but sterile connectivity must be maintained
Solution Approach 1:
A sterile drape or barrier with integrated conductive elements is used to physically separate the procedure user's hand from the sterile field while maintaining electrical connectivity. This flexible barrier allows the procedure user to operate switches adjacent to the surgical site without compromising sterile field integrity, as the drape prevents contamination while transmitting control signals.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables the procedure user to control nerve monitoring systems directly and safely within a sterile field, enhancing operational convenience and efficiency during procedures.
Implementation Method 1
The physical connection may include a wire (e.g. copper or aluminum wire), conductive polymer, or other appropriate conductive material. The physical connection may allow for both a signal from the remote to the monitoring system to interact with the monitoring system and/or to transmit a signal to and/or from the instrument.
Data Source
AI summary
A monitoring system may include a processor and display system for displaying results from the monitoring. A user may be in a sterile field away from the processor and display system and selected input devices. A controller may be physically connected to the monitoring system from the sterile field to allow the user to control the monitoring system.
