Surgical Robot Console Eye-Tracked Display Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The initial setup of surgical robotic systems is prone to human error due to the lack of automatic ergonomic adjustments, leading to suboptimal operating configurations and user discomfort, particularly in configuring the user console's seat and display positions.
Innovation Solution
An adjustable user console with an eye tracking system and actuators that automatically adjusts the seat and display column based on user input and eye position to ensure optimal ergonomic and operating configurations, ensuring the user's eyes are within the 3D perception and eye tracking workspaces and the UID is within the UID tracking workspace.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual configuration of the user console is performed, then the user can adjust the seat for comfort, but the display position may not be optimally configured due to lack of physical feedback
Solution Approach 1:
The system uses eye tracking technology to provide feedback about the user's viewing position and automatically adjusts the display column position to optimize the viewing angle and distance. This closes the loop between user position and display configuration, ensuring both comfort and precision.
Solution Approach 2:
The system performs self-configuration by automatically detecting the user's eye position and autonomously adjusting the display column without requiring manual intervention for display positioning, while still allowing manual seat adjustment for comfort.
2Manufacturing precision
If automatic configuration is implemented using eye tracking, then the display position precision is improved, but the device complexity increases
Solution Approach 1:
The patent replaces manual mechanical adjustment mechanisms with an automated optical sensing system (eye tracking) and electronic control system. This substitution reduces the need for complex manual adjustment mechanisms while achieving higher positioning precision through software-based control.
3Productivity
If the display column is automatically adjusted, then the operating efficiency is optimized, but the setup time increases due to additional configuration steps
Solution Approach 1:
The system performs preliminary configuration by automatically detecting eye position and adjusting the display column before the user begins the surgical procedure. This preliminary automatic setup eliminates the need for time-consuming manual trial-and-error adjustments during actual operation, optimizing operating efficiency.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The automatic configuration reduces the complexity of initial setup, enhances user comfort, and optimizes the operating efficiency by ensuring the user's optimal viewing experience and comfortable ergonomic positioning during prolonged surgical procedures.
Implementation Method 1
The system may include an eye tracking system that is arranged to detect a position of the user's eyes

AI summary
A method performed by a surgical robotic system that includes a seat that is arranged for a user to sit and a display column that includes at least one display for displaying a three-dimensional (3D) surgical presentation. The method includes receiving an indication that the user has manually adjusted the seat and in response, determining, while the user is sitting on the seat, a position of the user's eyes, determining a configuration for the display column based on the determined position of the user's eyes, and adjusting the display column by actuating one or more actuators of the display column according to the determined configuration.
