Solution Overview

Problem

Conventional methods for handling viscoelastic substances during cataract surgery require repeated insertion and retraction of separate injection and handling tools, leading to astigmatism and prolonged surgery time.

Innovation Solution

A surgical tool designed to integrate both injection and handling functions, with a body, a first gripping part, and a second gripping part protruding in opposite directions, allowing simultaneous injection and handling of viscoelastic substances without alternating tools.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If separate injection tool and handling tool are used alternately, then injection and handling functions are performed, but repeated insertion and retraction causes astigmatism and prolongs surgery time

Engineering Contradiction:

Improveinjection and handling function separationVSAvoidsurgery time

Core Design Contradiction:

Ease of operationVSLoss of time

Solution Approach 1:

The patent combines the injection tool and handling tool into a single integrated surgical tool. The tool includes a syringe holder for injecting viscoelastic substance and a chopper component for handling the substance, both integrated into one device that can perform multiple functions without requiring separate tools to be alternately inserted and retracted

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The surgical tool is designed with multi-functionality, allowing it to perform both injection of viscoelastic substance and handling operations within the lens capsule. The tool can switch between injection mode and handling mode without requiring tool replacement, making it a universal instrument for multiple surgical tasks

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Ease of operation

If separate injection tool and handling tool are used alternately, then specialized functions are performed, but repeated insertion and retraction causes astigmatism

Engineering Contradiction:

Improvespecialized function performanceVSAvoidastigmatism

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The patent merges the injection tool and handling tool into one integrated device, eliminating the need for repeated insertion and retraction of separate tools. The combined tool maintains specialized functions for both injection and handling while reducing mechanical disruptions to the cornea that cause astigmatism

Inventive Principle:

Principle #5Merging (Combining)

3Adaptability or versatility

If multiple separate tools are used for injection and handling, then specific tasks are performed, but device complexity increases

Engineering Contradiction:

Improveinjection and handling capabilityVSAvoidnumber of tools

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent integrates multiple separate tools (injection syringe and handling chopper) into a single surgical tool device. The integration maintains the adaptability and versatility of performing both injection and handling tasks while reducing the number of separate devices needed

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The surgical tool is designed as a universal instrument that can perform multiple functions including injection of viscoelastic substance and handling operations. This multi-functionality reduces device complexity by consolidating what would otherwise require multiple separate specialized tools

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A surgical tool for handling a viscoelastic substance syringe includes a body configured to allow a syringe in which a viscoelastic substance is stored to be coupled to the body in a front-rear direction, a first gripping part protruding from the body in one side direction perpendicular to the front-rear direction, and a second gripping part protruding from the body in an opposite direction to the one side direction.
