Surgical Interface Dynamics for Parameter Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current ophthalmic surgical interfaces are complex and difficult to navigate, lacking effective representation and control of various operating parameters, particularly in ultrasound power modes, which can complicate surgical procedures and reduce safety and effectiveness.
Innovation Solution
A graphical user interface that allows surgeons to adjust surgical device parameters by moving representations on a display screen, incorporating stages of procedures and using linear, logarithmic, or polynomial functions to control power modes such as continuous, pulsed, and burst ultrasound, along with fluidics parameters, enhancing visual organization and operational flexibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple operating parameters are displayed and controlled using traditional interfaces with fixed-position controls, then the system can provide comprehensive control over surgical parameters, but the interface becomes unnecessarily complicated and difficult to navigate
Solution Approach 1:
The interface allows dynamic reconfiguration of control elements. Instead of fixed-position controls, the system enables surgeons to customize the display and control of parameters by dragging and dropping control elements to desired positions on the screen, making the interface adaptable to individual surgical needs while reducing perceived complexity
Solution Approach 2:
The interface segments control parameters into distinct, manageable categories (e.g., ultrasound power, fluidics, mechanical settings). Each parameter can be independently controlled and displayed, allowing surgeons to focus on specific parameters without being overwhelmed by the complexity of controlling all parameters simultaneously
2Device complexity
If traditional fixed-position control interfaces are used, then the system structure is simple, but the ease of operation is reduced due to difficulty in navigating and adjusting multiple parameters
Solution Approach 1:
The interface transforms from a static, fixed-position control scheme to a dynamic system where control elements can be freely positioned and repositioned. This dynamic capability allows surgeons to create personalized control layouts that enhance ease of operation while maintaining relatively simple underlying system architecture
Solution Approach 2:
The interface introduces a customizable display layer as an intermediary between the surgical parameters and the surgeon's control inputs. This intermediary layer can be configured to present parameters in the most intuitive manner for each surgical task, significantly improving ease of operation without fundamentally changing the control system
3Adaptability or versatility
If the interface provides comprehensive control over multiple parameters including ultrasound power modes, then the adaptability for different surgical scenarios is improved, but the difficulty of detecting and measuring parameter values increases
Solution Approach 1:
The interface employs visual coding and color changes to represent different ultrasound power modes and parameter states. For example, different colors or color intensities can indicate continuous, pulsed, or burst modes, making parameter detection intuitive and reducing the cognitive load on surgeons while maintaining comprehensive control capabilities

AI summary
Graphical user interface system and method for displaying and controlling a surgical device, such as a device used in phacoemulsfication procedures. A graphical user interface is displayed on a display screen and includes one or more representations of operating parameters, such as aspiration rate, vacuum, and power that are used to control the surgical device. A parameter is adjusted by moving a portion of a representation from a first location on the display screen to a second location on the display screen to change the operating parameter and control the surgical device.
