Solution Overview

Problem

Existing treatment devices for coagulation and incision of living tissue using high-frequency energy often require multiple types of forceps and manual operation, leading to increased surgical time and risk of tissue damage due to the need for sharp blades.

Innovation Solution

A treatment device with a pair of jaws capable of opening and closing, featuring electrode portions and a tissue pressing mechanism that uses high-frequency current to coagulate and incise tissue without a knife, allowing for selective operation modes via foot pedals to control coagulation and incision, reducing the need for multiple forceps and minimizing tissue trauma.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple types of forceps are used for different treatments, then treatment versatility is improved, but device complexity and surgical time increase

Engineering Contradiction:
Improvetreatment versatilityVSAvoiddevice complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The forceps integrates both coagulation and incision functions into a single device. The first electrode portion enables coagulation treatment, while the second electrode portion enables incision treatment. This multi-functional design eliminates the need for multiple separate forceps, reducing device complexity and surgical time while maintaining treatment versatility.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Ease of operation

If a knife is used for incision, then incision capability is improved, but risk of tissue damage increases

Engineering Contradiction:
Improveincision capabilityVSAvoidtissue damage
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The device replaces the mechanical knife system with an electromagnetic field-based incision system. The second electrode portion generates high-frequency current that flows through the tissue to produce heat for incision, eliminating the need for sharp blades and reducing mechanical tissue damage while maintaining effective incision capability.

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

3Ease of operation

If manual operation is required for treatment switching, then operational flexibility is improved, but surgical time increases

Engineering Contradiction:
Improveoperational flexibilityVSAvoidsurgical time
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The device enables self-service operation through foot pedal control. The operator can switch between coagulation and incision modes by simply pressing different pedals, allowing hands-free operation during critical procedures. This automatic mode switching reduces surgical time while maintaining operational flexibility.

Inventive Principle:
Principle #25Self-service

Applied Scientific Principles
