Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Wounds in the eye are difficult to visualize and suture due to fluid obscuration and tissue closure, complicating ophthalmological procedures.

Innovation Solution

A forceps with a transparent projection at the distal end that presses against the wound to displace fluids and enhance visibility, allowing for accurate suture placement.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If conventional forceps are used to access the wound, then the wound can be grasped and manipulated, but the wound remains difficult to see due to fluid obscuration and tissue closure

Engineering Contradiction:

Improvewound visualizationVSAvoidwound visibility

Core Design Contradiction:

Ease of operationVSDifficulty of detecting and measuring

Solution Approach 1:

A transparent projection is added to the forceps as an intermediary element that allows the surgeon to press against the wound to displace fluids and spread tissues, thereby improving wound visibility without interfering with the grasping function of the forceps

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The forceps combines two previously separate functions into one instrument: the grasping function (original forceps capability) and the wound spreading/visualization function (new transparent projection capability), allowing both functions to be performed simultaneously

Inventive Principle:

Principle #5Merging (Combining)

2Difficulty of detecting and measuring

If the wound is pressed to open it for visualization, then visibility improves, but the natural tendency of tissues to press closed creates resistance

Engineering Contradiction:

Improvewound visibilityVSAvoidtissue resistance

Core Design Contradiction:

Difficulty of detecting and measuringVSForce

Solution Approach 1:

The transparent projection serves as a mediator that distributes the pressing force across a larger area, reducing the concentrated resistance from tissues while still achieving wound opening and fluid displacement for better visualization

Inventive Principle:

Principle #24Intermediary (Mediator)

3Productivity

If a needle is inserted to suture the wound, then the wound can be closed, but the resistance of tissues to needle insertion makes suturing difficult

Engineering Contradiction:

Improvesuturing efficiencyVSAvoidneedle insertion resistance

Core Design Contradiction:

ProductivityVSForce

Solution Approach 1:

The transparent projection is used to pre-open and stabilize the wound before needle insertion, creating a more favorable pathway and reducing the resistance encountered during suturing

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The transparent projection acts as a stabilizing intermediary that holds the wound open and provides a clear visual guide during needle insertion, making the suturing process more efficient

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

Devices and methods to stabilize an eye and suture with wound visibility are shown. In selected examples, a forceps is shown that includes one or more transparent projections. In use, the one or more transparent projections can be concurrently pressed against the wound while holding an eye stable with gripping surfaces of the forceps. The one or more transparent projections and the gipping of the forceps work together to aid in a suture placement.
