Gastrointestinal Full-Thickness Resection Marking

Solution Overview

Problem

During endoscopic full-thickness resection of the gastrointestinal tract, the escape of air into the abdominal cavity causes deformation, making it difficult for surgeons to accurately identify and suture the resected site, as existing methods lack effective marking and suturing solutions to maintain visibility and precision.

Innovation Solution

A method involving the formation of pair markings on the gastrointestinal tract's peripheral tissues to sandwich the lesion, followed by precise suturing at these marked locations using a medical stapler attached to an endoscope, ensuring accurate suture placement despite air escape and deformation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If full-thickness resection is performed on the gastrointestinal tract, then the lesion can be completely removed, but air escapes into the abdominal cavity causing deformation that makes it difficult to grasp and suture the resected site

Engineering Contradiction:

Improvecomplete lesion removalVSAvoidgrasping and suturing the resected site

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent applies preliminary action by marking the peripheral tissues on both sides of the lesion before performing the full-thickness resection. These markings serve as reference points that remain visible even after air escape and deformation, enabling the surgeon to accurately identify and suture the resected site without difficulty.

Inventive Principle:

Principle #10Preliminary action

2Device complexity

If no markings are made before resection, then the procedure is simpler, but the surgeon cannot accurately identify the suture location after air escape and deformation

Engineering Contradiction:

Improveprocedure simplicityVSAvoidsuture location identification

Core Design Contradiction:

Device complexityVSMeasurement precision

Solution Approach 1:

The patent applies preliminary action by marking the peripheral tissues on both sides of the lesion before performing the full-thickness resection. These markings serve as reference points that remain visible even after air escape and deformation, enabling the surgeon to accurately identify and suture the resected site without difficulty.

Inventive Principle:

Principle #10Preliminary action

3Productivity

If the gastrointestinal tract is resected without markings, then the operation is faster, but the deformation caused by air escape makes it difficult to maintain visibility and precision during suturing

Engineering Contradiction:

Improveoperation speedVSAvoidsuture placement precision

Core Design Contradiction:

ProductivityVSManufacturing precision

Solution Approach 1:

The patent applies preliminary action by marking the peripheral tissues on both sides of the lesion before performing the full-thickness resection.

AI summary

A full-thickness resection method for a gastrointestinal tract includes forming a pair of first markings in surrounding tissue on both sides of a lesion to sandwich the lesion therebetween; performing a full-thickness resection to a portion including the lesion; identifying a pair of suture locations in the vicinity of the pair of first markings; and suturing the pair of first suture locations.
