Solution Overview
Problem
Current nerve stimulation methods, such as Continuous Radiofrequency and Pulsed Radiofrequency, face challenges with nerve tissue healing and the formation of neuroma, leading to persistent pain, and existing devices require precise control of pulse duration and temperature to avoid tissue damage.
Innovation Solution
An embedded electromagnetic stimulation device using low-power, low-temperature, high-frequency electromagnetic fields, generated by positive and negative electrodes separated by specific distances, applies a preset voltage between 200 KHz and 800 KHz to increase nerve threshold and reduce pain without damaging nerve tissue.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If continuous high-frequency signal is applied to create high temperature, then nerve pain is alleviated by destroying nerve tissue, but neuroma is formed and causes more serious pain
Solution Approach 1:
The patent applies pulsed radiofrequency stimulation instead of continuous high-frequency signal. The stimulation is delivered in intermittent pulses (e.g., 20ms on, 80ms off) which prevents sustained high temperature buildup, thereby avoiding nerve tissue destruction and neuroma formation while still providing pain relief through repeated threshold modulation
Solution Approach 2:
The patent changes the temperature parameter from high temperature (above 42°C) to low temperature (below 42°C) operation. By controlling the stimulation parameters to maintain low temperature, the patent achieves pain relief through nerve threshold modulation without causing tissue damage or neuroma formation
2Object-affected harmful factors
If pulsed radiofrequency stimulation is used to avoid high temperature damage, then neuroma formation is prevented, but precise control of pulse duration and temperature is required
Solution Approach 1:
The patent employs a self-regulating pulsed stimulation mechanism where the intermittent pulse delivery inherently limits temperature accumulation. The system automatically prevents overheating through its pulsed operation mode, reducing the need for complex external temperature monitoring and control systems while maintaining tissue safety
3Reliability
If high-frequency electromagnetic field stimulation is applied, then nerve threshold is increased and pain is reduced, but the mechanism must avoid biomolecule production that could lead to tissue damage
Solution Approach 1:
The patent utilizes high-frequency electromagnetic field stimulation at frequencies and power levels that modulate nerve thresholds without triggering significant biomolecule production. By operating in a specific parameter range, the patent achieves pain relief through nerve threshold elevation while avoiding the harmful biological responses associated with tissue damage

AI summary
A high frequency electromagnetic field stimulator for changing nerve threshold comprises at least one electrical stimulator (1), the electrical stimulator (1) comprises at least one positive electrode terminal (12) and at least one negative electrode terminal (13), an insulating spacing of a first gap (b) is arranged between the positive and negative electrode terminals, the positive and negative electrode terminals are a second gap distance (c) away from a to-be-stimulated nerve, a voltage is electrically conducted by the electrical stimulator (1), and the voltage is caused to be less than or equal to 10 V and has a frequency ranging from 200 KHz to 800 KHz. An electromagnetic field is generated by the positive electrode terminal (12) and the negative electrode terminal (13) of the electrical stimulator and is enabled to cover the to-be-stimulated nerve (2) therearound to perform a low-intensity electromagnetic stimulus on the to-be-stimulated nerve, thereby increasing the thresholds of the electromagnetically-stimulated neural regions and achieving the effect that neuropathic pain a patient feels is reduced effectively.
