Solution Overview

Problem

Current treatment systems using ultrasound energy for body tissue treatment face challenges in accurately determining the completion of procedures like incision, as they rely on single parameters which can be influenced by tissue type and environmental conditions, leading to potential over-treatment or under-treatment.

Innovation Solution

A system that generates training data by combining ultrasound and high-frequency energy parameters, using machine learning to create an estimation model that determines treatment completion based on multiple energy metrics, preventing unnecessary damage to tissues.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If single parameter monitoring is used to determine treatment completion, then the system is simple to operate, but the measurement precision is insufficient due to tissue type and environmental condition variations

Engineering Contradiction:
Improvetreatment completion detection accuracyVSAvoidsystem complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent combines multiple energy parameters (ultrasound energy parameters including impedance and power, and high-frequency energy parameters including impedance and power) into a unified monitoring system. This merging of multiple measurement dimensions enables accurate treatment completion detection without requiring complex separate systems for each parameter, as the control device integrates all measurements and uses machine learning models to synthesize the information.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent introduces machine learning estimation models as intermediaries that process multiple raw energy parameters and translate them into treatment completion predictions. These models act as mediators between the complex multi-parameter measurements and the simple binary decision of treatment completion, enabling high precision while maintaining operational simplicity through automated intelligent analysis.

Inventive Principle:
Principle #24Intermediary (Mediator)

If multiple energy parameters are monitored and combined using machine learning, then the measurement precision improves, but the device complexity increases

Engineering Contradiction:

Core Design Contradiction:

Solution Approach 1:

The system employs self-service through automated machine learning models that automatically process multiple energy parameters and determine treatment completion without requiring complex manual intervention. The control device autonomously integrates ultrasound and high-frequency energy parameters, applies pre-trained estimation models, and generates treatment completion predictions, thereby improving reliability while keeping the operational interface simple.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent applies preliminary action by pre-training machine learning estimation models with extensive data before actual treatment use. This preliminary model training phase allows the system to handle complex multi-parameter analysis during treatment without requiring complex real-time processing, as the decision-making logic has already been established in advance through machine learning training.

Inventive Principle:

Solution Approach 1:

The patent implements comprehensive feedback by continuously monitoring multiple energy parameters (ultrasound impedance, ultrasound power, high-frequency impedance, high-frequency power) and using machine learning models to provide real-time treatment completion feedback. This multi-dimensional feedback loop enables precise treatment application while maintaining ease of operation, as the system automatically processes the feedback and guides the treatment process without requiring complex manual analysis from the operator.

Inventive Principle:
Principle #23Feedback
