Solution Overview

Problem

Current treatments for cervical intraepithelial neoplasia are heavily dependent on practitioner skill and experience, leading to inconsistent results due to the inability to visually detect pathological tissue changes, resulting in over-treatment, under-treatment, or irregular treatment.

Innovation Solution

A treatment device comprising a diagnostic device for imaging and identifying tissue pathology, an application device for applying a non-thermal plasma treatment medium, and a navigation device for controlling treatment intensity based on location-specific diagnosis, creating a treatment plan card that guides the practitioner in delivering precise therapy recommendations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If practitioner skill and experience are relied upon for treatment, then treatment flexibility is maintained, but treatment consistency and precision deteriorate

Engineering Contradiction:
Improvetreatment flexibilityVSAvoidtreatment consistency
Core Design Contradiction:
Ease of operationVSManufacturing precision

Solution Approach 1:

The system creates a digital copy (treatment plan map) of the tissue pathology based on image analysis, which then guides the treatment process. This digital replica allows standardized treatment protocols to be applied consistently while maintaining the ability to adjust based on the specific copied data, resolving the contradiction between flexibility and consistency.

Inventive Principle:
Principle #26Copying

Solution Approach 2:

The system automatically adjusts treatment parameters (energy dose, exposure time, intensity) based on analyzed tissue characteristics and pre-defined treatment protocols. This automated parameter adjustment ensures consistent treatment delivery while allowing flexibility through protocol selection and modification, directly addressing the contradiction.

Inventive Principle:
Principle #35Parameter changes

2Ease of operation

If visual inspection methods are used to identify pathological tissue, then treatment simplicity is maintained, but measurement precision deteriorates

Engineering Contradiction:
Improvetreatment simplicityVSAvoidpathology detection accuracy
Core Design Contradiction:
Ease of operationVSMeasurement precision

Solution Approach 1:

The system replaces manual visual inspection with automated image analysis using diagnostic devices and software algorithms. This substitution maintains operational simplicity through automated processing while dramatically improving measurement precision in detecting and characterizing pathological tissue, directly resolving the contradiction.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The system introduces an intermediary layer (image analysis software and diagnostic devices) between the practitioner and the tissue. This intermediary automatically performs precise measurements and generates treatment recommendations, maintaining simplicity for the practitioner while achieving high measurement precision through automated analysis.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Ease of operation

If uniform treatment intensity is applied across all tissue areas, then treatment process simplicity is maintained, but treatment effectiveness deteriorates

Engineering Contradiction:
Improvetreatment process simplicityVSAvoidtreatment effectiveness
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The system applies the principle of local quality by determining treatment parameters based on location-specific tissue characteristics identified through image analysis. Each area receives treatment intensity and duration tailored to its specific pathology, improving treatment effectiveness while maintaining process simplicity through automated localization and parameter assignment.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The system automatically changes treatment parameters (intensity, duration, energy dose) based on the specific characteristics of different tissue areas identified in the treatment plan map. This automated parameter variation ensures each area receives appropriate treatment for its condition, improving effectiveness without complicating the treatment process for the practitioner.

Inventive Principle:
Principle #35Parameter changes

Implementation Method 1

The instrument (19) is an instrument for applying a treatment medium to tissue, in particular an instrument for generating an argon plasma stream. The plasma is preferably not in thermal equilibrium. It preferably has a gas temperature (i.e. temperature of the heavy particles; e.g. argon atoms in the case of an argon plasma) that is significantly lower than the electron temperature

Methodology Applied
Scientific EffectPlasma: Plasma

Implementation Method 2

The plasma is preferably not in thermal equilibrium. It preferably has a gas temperature (i.e. temperature of the heavy particles; e.g. argon atoms in the case of an argon plasma) that is significantly lower than the electron temperature, so that human tissue can be contacted by the plasma

Methodology Applied
Scientific EffectNon-thermal plasma: Plasma

Implementation Method 3

The diagnostic device (15) has an image recording device (16) for recording at least one image, an image sequence or a video of the tissue

Methodology Applied
Scientific EffectOptical imaging: Photography

Implementation Method 4

Cervical intraepithelial neoplasias are typically identified through a staining test, in which the tissue area to be examined is treated with acetic acid solution and then with iodine-potassium iodide solution, resulting in a gradually fading acetic white or iodine-negative staining of the tissue

Methodology Applied
Scientific EffectChemical staining: Absorption Spectroscopy
