Phacoemulsification GUI for Dynamic Pulse Mode Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current graphical user interfaces for phacoemulsification surgical systems are complex and lack intuitive control over pulse modes, particularly in representing and adjusting the on-time and off-time parameters, which limits surgeons' ability to easily switch between and customize different ultrasound modes.
Innovation Solution
A graphical user interface that allows surgeons to quickly select and adjust pulse modes by varying the on-time and off-time representations linearly, non-linearly, or keeping them constant in response to foot pedal displacement, enabling the generation of multiple pulse modes, including hybrid modes, through touch-screen interactions and menu selections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple pulse modes (continuous, linear, pulse, burst) are supported with separate controllers and fixed parameter fields, then the system can accommodate different operating modes, but the user interface becomes complex and difficult to manipulate
Solution Approach 1:
The graphical user interface uses a single unified display element that can represent multiple pulse modes (continuous, linear, pulse, burst) through different graphical representations. The same display element adapts its visualization based on the selected mode, eliminating the need for separate controllers for each mode and reducing interface complexity while maintaining versatility
Solution Approach 2:
The display element dynamically changes its graphical representation based on the selected pulse mode and real-time parameter values. The visualization transitions between different modes (continuous line, stepped line, pulse waveforms) and updates on-time/off-time representations as parameters change, providing an adaptive interface that responds to user interactions
2Ease of operation
If on-time and off-time parameters are fixed or vary linearly with foot pedal displacement, then the system is simple to control, but the surgeon cannot customize pulse characteristics for different surgical needs
Solution Approach 1:
The system provides preset pulse mode configurations (continuous, linear, pulse, burst) that are pre-configured with characteristic on-time and off-time relationships. These presets are automatically applied when selected, providing immediate customized control without requiring manual parameter adjustment, thus maintaining ease of operation while enabling customization
Solution Approach 2:
The on-time and off-time parameters dynamically adjust based on foot pedal displacement according to the selected pulse mode characteristics. The system automatically varies these parameters in real-time to match the desired pulse behavior, allowing surgeons to customize pulse modes without manually setting individual parameters
3Ease of manufacture
If the interface displays fixed parameter fields for each pulse mode, then parameter setting is straightforward, but switching between modes requires manual selection and reconfiguration
Solution Approach 1:
The graphical display element automatically transforms its visualization when pulse modes are switched. The same display element continuously updates to show the appropriate representation (continuous power line, stepped linear mode, pulse waveforms with varying on-time/off-time) based on the currently selected mode, eliminating the need for manual reconfiguration of separate parameter fields
Solution Approach 2:
Multiple pulse mode controls and parameter displays are merged into a single unified graphical user interface element. This consolidation allows mode switching to occur automatically through the existing foot pedal control mechanism, reducing mode switching time while maintaining ease of implementation

AI summary
A graphical user interface for use in phacoemulsification surgical systems that allows a user to select different pulse modes by touching portions of the display screen. The user interface includes first and second display elements. One display element includes a representation of the on-time of the pulses, and the other display element includes a representation of the off-time. The representations show how the on-time and off-time change relative to a position of a controller, such as a foot pedal. The representation show a constant time, or that a time increases or decreases as the foot pedal is pressed. To select a pulse mode, a user can scroll through different pulse representations by touching the screen at the display elements. The selected pulse mode can be continuous, pulse, burst, or a combination or derivation thereof.
