Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Current anastomosis procedures are prone to complications due to the skill and experience of the physician, leading to prolonged times, improper suturing, blood leakage, and tissue damage, especially in connecting tubular bodies like blood vessels or intestinal sections.

Innovation Solution

An anastomosis suturing device with a dismantable casing, tubular sections, needle activators, and drivers that facilitate the insertion and protrusion of suture needles through the tubular bodies, reducing manual handling and enabling faster and more precise suturing.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If manual suturing is used to connect tubular bodies, then the physician can control the suturing process, but the procedure takes prolonged time and is prone to complications due to skill and experience limitations

Engineering Contradiction:

Improvesuturing accuracyVSAvoidprocedural time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The device enables self-aligning and self-suturing functionality where the tubular sections automatically position themselves and the suturing mechanism operates without continuous manual intervention, reducing procedural time while maintaining reliability through automated precision

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The invention replaces manual mechanical suturing with an automated mechanical system that includes needle drivers, suture feeders, and cutting mechanisms, eliminating the dependency on physician skill and experience while reducing procedural time

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Ease of operation

If manual handling is used during anastomosis, then the physician can adjust suturing in real-time, but tissue damage and blood leakage risks increase

Engineering Contradiction:

Improvemanual controlVSAvoidtissue damage

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The device performs self-contained suturing operations where the automated mechanism handles needle insertion, suture feeding, and cutting, minimizing manual handling of delicate tissues while reducing the risk of tissue damage and blood leakage

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The device acts as an intermediary between the physician's intent and the actual suturing action, using automated mechanisms to perform precise operations that minimize direct manual contact with vulnerable tissues

Inventive Principle:

Principle #24Intermediary (Mediator)

3Productivity

If automated suturing device is used, then procedural time is reduced and precision is improved, but device complexity increases

Engineering Contradiction:

Improvesuturing speedVSAvoiddevice structure

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The device is divided into modular functional components including tubular sections with integrated needles, needle drivers, suture storage, and cutting mechanisms, allowing each segment to perform a specific function efficiently while reducing overall system complexity through functional decomposition

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The device integrates multiple functions into a single unified system where the same structural components serve multiple purposes - tubular sections provide structural support and needle guidance, while also serving as the anastomosis structure itself, thereby reducing device complexity despite high productivity

Inventive Principle:

Principle #6Universality (Multi-functionality)
