Solution Overview

Problem

Existing treatments for mucosal tissue abnormalities, such as vaginal relaxation, fail to effectively maintain tissue contractility and elasticity while ensuring safety and minimizing damage to surrounding tissues and nerves, and are often lengthy and uncomfortable for the patient.

Innovation Solution

A submucosa treating apparatus with a probe and electrode that applies electrical signals to blood vessels, guided by a movable and rotatable mechanism, allowing precise control and minimizing thermal damage to surrounding tissues.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If a scalpel is used to incise the submucosa, then the incision can be made, but the incision depth is difficult to control and bleeding occurs

Engineering Contradiction:
Improveincision depth controlVSAvoidbleeding
Core Design Contradiction:
Manufacturing precisionVSObject-generated harmful factors

Solution Approach 1:

The patent replaces the mechanical scalpel cutting system with an energy-based RF electrosurgical system. The RF electrode delivers controlled energy through the mucosa to the submucosa, creating a cutting effect without mechanical contact, thereby achieving precise depth control and minimizing bleeding through coagulation.

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

Solution Approach 2:

The patent changes the physical state and parameters of energy delivery by using RF electromagnetic energy with specific impedance matching and controlled power delivery. The system monitors and adjusts energy parameters to achieve precise thermal effects in the submucosa while sparing deeper tissues, enabling controlled incision depth and reduced bleeding.

Inventive Principle:
Principle #35Parameter changes

2Reliability

If RF energy is applied to treat the submucosa, then the submucosa can be treated, but excessive energy may damage surrounding healthy tissue

Engineering Contradiction:
Improvetreatment effectivenessVSAvoiddamage to surrounding healthy tissue
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent applies RF energy locally and selectively to the submucosa through a positioned electrode. The energy delivery is concentrated at the treatment site with controlled spatial distribution, allowing effective submucosal treatment while limiting thermal spread to surrounding healthy tissues through precise electrode positioning and controlled energy parameters.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The patent incorporates impedance sensing and temperature monitoring feedback mechanisms that detect tissue conditions in real-time. The system automatically adjusts energy delivery based on feedback signals, reducing energy input when adequate treatment effect is achieved or when approaching safe thermal limits, thereby preventing damage to surrounding healthy tissue while ensuring effective submucosal treatment.

Inventive Principle:
Principle #23Feedback
