Solution Overview

Problem

Current endoscopic procedures for removing gastrointestinal tract lesions are time-consuming and invasive, requiring multiple instruments for excision, cautery, and irrigation, which can cause trauma and increase procedural time and cost.

Innovation Solution

A combined electro-cautery and electro-cutting device with a flexible tube, an elongate member for cutting tissue, and a cauterizing member that moves relative to the tube, allowing simultaneous excision, cautery, and irrigation without the need for multiple instruments.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If multiple endoscopic instruments are used for excision, cautery, and irrigation, then complete lesion removal is achieved, but procedural time increases and patient trauma increases

Engineering Contradiction:

Improvecomplete lesion removalVSAvoidprocedural time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The patent combines multiple endoscopic instruments (excision device, cautery device, and irrigation device) into a single integrated device. The device includes an elongate member with a cutting edge for excision, a cauterizing member with electrical conductive material for cautery, and a fluid delivery system for irrigation, all accessible through a single endoscopic instrument. This merging eliminates the need to insert and remove multiple separate instruments during the procedure, thereby reducing procedural time while maintaining complete lesion removal capability.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The integrated device performs multiple functions through a single instrument: it can excise tissue using the elongate member with cutting edge, apply cautery using the cauterizing member with electrical conductive material, and deliver irrigation fluid through the fluid delivery system. This multi-functionality allows the device to replace several specialized instruments, reducing the overall procedural time while ensuring all necessary steps for complete lesion removal are accomplished.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Reliability

If multiple endoscopic instruments are used for excision, cautery, and irrigation, then complete lesion removal is achieved, but patient trauma increases

Engineering Contradiction:

Improvecomplete lesion removalVSAvoidpatient trauma

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

By merging excision, cautery, and irrigation functions into a single endoscopic device, the patent reduces the number of times instruments need to be inserted and removed from the patient's body. The single instrument approach minimizes mechanical trauma to the gastrointestinal tract while maintaining the ability to perform complete lesion removal through coordinated use of the elongate member, cauterizing member, and fluid delivery system.

Inventive Principle:

Principle #5Merging (Combining)

3Adaptability or versatility

If multiple instruments are inserted and removed repeatedly, then each function can be performed, but device complexity and procedural steps increase

Engineering Contradiction:

Improvefunctional capabilityVSAvoidnumber of instruments

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent merges multiple separate instruments into a single integrated device that incorporates an elongate member for excision, a cauterizing member with electrical conductive material, and a fluid delivery system. This consolidation reduces the number of discrete instruments from three or more to one, simplifying the overall device complexity while preserving all necessary functional capabilities for complete lesion removal.

Inventive Principle:

Principle #5Merging (Combining)
