Solution Overview
Problem
Current treatments for skin warts, such as over-the-counter products and liquid nitrogen, often fail to provide effective and long-lasting solutions, leading to recurrence and frustration for both patients and dermatologists.
Innovation Solution
The use of non-thermal, atmospheric pressure plasma is employed to treat warts by guiding it over the affected areas, utilizing a device with a high-voltage electrode, insulating barrier, and power source to generate non-thermal plasma without causing thermal damage to the tissue.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional treatments such as liquid nitrogen or over-the-counter products are used to treat warts, then the treatment process is simple and accessible, but the effectiveness is poor and recurrence is common
Solution Approach 1:
The patent replaces conventional mechanical or chemical wart removal methods (such as liquid nitrogen freezing or topical salicylic acid applications) with a plasma-based treatment system. The plasma device uses controlled electrical discharge to generate reactive species that selectively destroy wart tissue, thereby improving treatment effectiveness and reducing recurrence while maintaining practical usability through a handheld applicator design.
2Duration of action of moving object
If aggressive treatments are applied to remove warts quickly, then the treatment duration is reduced, but the risk of tissue damage and scarring increases
Solution Approach 1:
The patent employs precise control of plasma generation parameters including voltage, current, gas flow rate, and treatment duration. By optimizing these parameters, the system achieves effective wart removal within seconds to minutes while maintaining tissue temperature and energy levels that prevent damage to surrounding healthy skin, thereby eliminating the trade-off between treatment speed and safety.
Solution Approach 2:
The patent introduces a controlled plasma field as an intermediary between the energy source and the wart tissue. This plasma mediator delivers therapeutic effects through reactive oxygen and nitrogen species that selectively target abnormal cells, while the system's control mechanisms ensure that energy delivery remains within safe thresholds, preventing thermal or electrical damage to surrounding tissues.
3Object-affected harmful factors
If multiple treatment sessions are scheduled to ensure complete wart removal, then the risk of tissue damage is reduced, but the treatment time and patient burden increase
Solution Approach 1:
The patent achieves complete wart removal in a single continuous treatment session by maintaining optimal plasma discharge conditions throughout the procedure. The system continuously delivers controlled plasma energy across the entire wart surface, ensuring thorough destruction of all abnormal tissue without interruption, thereby eliminating the need for multiple follow-up appointments while maintaining safety through real-time parameter monitoring.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This method achieves partial to complete amelioration of warts with minimal risk of tissue damage, as demonstrated by clinical trials where all lesions of one patient resolved and a new wart cleared with subsequent treatments, although recurrence was noted in another patient.
Implementation Method 1
a high voltage electrode, an insulating or semiconducting barrier, a power source capable of providing a voltage, and a pulse generator. The device is capable of generating non thermal plasma
Implementation Method 2
guiding non-thermal, atmospheric pressure plasma over areas of the tissue having the wart

Data Source
AI summary
A method for treating a wart on skin of a patient includes guiding non-thermal, atmospheric pressure plasma over areas of the tissue having the wart for a length of time effective to give rise to an at least partial amelioration of the wart.
