Solution Overview

Problem

Existing devices for anastomosis of hollow organs, such as blood vessels, face challenges in efficiently turning vessel ends over sleeves without damaging the vessels and require specific fittings for different organ diameters, making the process cumbersome and prone to errors.

Innovation Solution

A sleeve with an adjustable diameter, made of expandable material mesh, and a turning-over device using pressurized fluid to facilitate the turning-over of vessel ends, allowing for secure contact and connection of hollow organs with varying diameters.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If traditional stitching or manual turning-over methods are used, then the surgeon can connect blood vessels, but the process takes a lot of time and requires multiple people, reducing productivity

Engineering Contradiction:

Improveanastomosis speedVSAvoidsurgical time

Core Design Contradiction:

ProductivityVSLoss of time

Solution Approach 1:

The patent replaces manual mechanical turning-over operations with an automated mechanical turning-over device that uses a turning-over member and elastic member to automatically evert the vessel end over the sleeve, eliminating the need for multiple pairs of tweezers and manual manipulation by multiple surgeons

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The turning-over device uses an elastic member that automatically expands to push the vessel end over the sleeve and then retracts, performing the turning-over action autonomously without requiring continuous manual intervention or coordination between multiple surgical assistants

Inventive Principle:

Principle #25Self-service

2Manufacturing precision

If specific fittings and sleeves are used for each hollow organ diameter, then the connection can be precise, but the device complexity increases and requires multiple different components

Engineering Contradiction:

Improveconnection precisionVSAvoidnumber of different fittings

Core Design Contradiction:

Manufacturing precisionVSDevice complexity

Solution Approach 1:

The patent designs the sleeve with a compressible elastic member that can be adjusted to fit different vessel diameters, allowing a single universal device to accommodate various organ sizes rather than requiring separate fitted components for each diameter

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The elastic member of the sleeve is designed to be dynamically compressible and expandable, allowing it to adapt its diameter to match different vessel sizes during the anastomosis procedure, providing precision for various diameters with a single adjustable component

Inventive Principle:

Principle #15Dynamics

3Ease of operation

If manual turning-over with tweezers is used, then the vessel end can be turned over, but the risk of vessel damage increases due to difficult manipulation

Engineering Contradiction:

Improveturning-over easeVSAvoidvessel damage risk

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The patent replaces the delicate manual manipulation with tweezers with a dedicated turning-over device that uses a turning-over member to gently engage and evert the vessel end, and an elastic member to provide controlled pushing force, eliminating the pinching and grasping actions that risk damaging the vessel

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The turning-over member acts as an intermediary between the surgeon's control and the vessel end, providing a specialized interface that is gentle on the tissue, while the elastic member serves as a mediator that translates controlled compression into the gentle pushing force needed to turn over the vessel without direct manual contact

Inventive Principle:

Principle #24Intermediary (Mediator)
