Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing ophthalmic surgical displays often obscure the surgeon's view, are overcrowded, and use distracting ring-shaped patterns, making them inconvenient and less usable during procedures.

Innovation Solution

A display system for ophthalmic surgical consoles that generates non-overlapping, user-selectable display sectors on an image of the patient's eye, allowing surgeons to customize and prioritize surgical parameters without obstructing the view, using a processor-controlled display device integrated with the surgical microscope.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If additional information is included in the display, then the amount of surgical parameters displayed is improved, but the display becomes crowded and less usable

Engineering Contradiction:

Improvesurgical parameter informationVSAvoiddisplay usability

Core Design Contradiction:

Loss of informationVSEase of operation

Solution Approach 1:

The display is divided into multiple separate display sectors, each dedicated to showing a specific surgical parameter. This segmentation allows multiple parameters to be displayed simultaneously without crowding, as each parameter occupies its own designated sector rather than competing for space in a single display area.

Inventive Principle:

Principle #1Segmentation

2Loss of information

If display information is placed on the surgical microscope view, then information accessibility is improved, but the surgeon's view of the eye is obscured

Engineering Contradiction:

Improvesurgical parameter visibilityVSAvoidview obstruction

Core Design Contradiction:

Loss of informationVSObject-affected harmful factors

Solution Approach 1:

Different display sectors are positioned in specific regions of the composite image where they are least likely to obscure the surgical field. The display sectors are strategically located to minimize interference with the surgeon's view of the eye while still providing accessible parameter information.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The display sectors are overlaid on the composite image in a way that utilizes the two-dimensional space efficiently, placing information in peripheral or less critical viewing zones rather than blocking the central surgical field.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

3Measurement precision

If ring-shaped patterns with measurement scales are used, then measurement functionality is improved, but the patterns become distracting to the surgeon

Engineering Contradiction:

Improveparameter measurement capabilityVSAvoidsurgeon distraction

Core Design Contradiction:

Measurement precisionVSObject-affected harmful factors

Solution Approach 1:

The display sectors utilize color coding to differentiate between various surgical parameters and their measurement states. Different colors or color intensities indicate different parameter values or alert states, providing measurement information through color variation rather than distracting ring patterns.

Inventive Principle:

Principle #32Color changes

AI summary

An ophthalmic surgical system includes a display device and a user interface. The display device generates a display on an image of a patient's eye comprising a plurality of non-overlapping display sectors. Each display sector displays one of a plurality of user-selectable surgical parameters. A user interface receives a user selection of one or more of the user-selectable surgical parameters to be displayed.
