Surgical Headset Display for Phacoemulsification Imaging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current surgical methods for phacoemulsification, such as those using microscopes, require surgeons to frequently pause and change their gaze between the surgical site and the surgical console, leading to decreased surgical efficiency and potential discomfort due to awkward head positioning.
Innovation Solution
A surgical imaging system that includes a headset with a semi-transparent screen, allowing surgeons to view real-time visual and thermal images of the eye during a phacoemulsification procedure without needing to pause or change their gaze, while also enabling them to see a second field of view for monitoring other aspects of the surgery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a microscope is used for visualization and magnification of the surgical site, then the surgeon can view the surgical site with magnification, but the surgeon must frequently pause and change gaze between the surgical site and the surgical console, decreasing surgical efficiency
Solution Approach 1:
The patent combines multiple imaging modalities (optical coherence tomography, infrared thermography, visible light imaging) into a single integrated surgical imaging system that displays all images simultaneously on a single display device, allowing the surgeon to view multiple parameters without pausing or changing gaze between separate consoles
Solution Approach 2:
The patent adds a new dimension of thermal imaging capability to the traditional optical imaging system, enabling the surgeon to monitor temperature distribution at the surgical site alongside anatomical structures in the same field of view, providing comprehensive visualization without requiring separate viewing actions
2Measurement precision
If a microscope is used for visualization of the surgical site, then the surgeon can achieve magnification, but the surgeon must hold the head at an awkward angle, causing fatigue and discomfort over time
Solution Approach 1:
The patent creates a virtual copy of the surgical site visualization that can be viewed on a display device positioned at an ergonomic angle for the surgeon, eliminating the need to maintain an awkward head position while still providing magnified and detailed views through the imaging system
3Loss of information
If the surgeon checks settings or surgical parameters on the surgical console, then the surgeon can monitor surgical parameters, but the surgeon must pause surgery and change gaze from the surgical site to the console, decreasing efficiency
Solution Approach 1:
The patent merges the display of surgical parameters and imaging data into a single integrated display interface that presents thermal images, optical coherence tomography images, and surgical settings simultaneously, allowing the surgeon to monitor all parameters without pausing or shifting attention between separate consoles
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
This system enhances surgical efficiency by allowing continuous visualization of the surgical site without the need for frequent gaze changes, reducing fatigue and improving comfort for the surgeon.
Implementation Method 1
a second imaging device configured to generate a real-time thermal image of the first field of view
Implementation Method 2
a semi-transparent screen configured to be mounted on the structure in front of the eye of the operator

AI summary
A surgical imaging system, including a first imaging device configured to generate a real-time visual image of a first field of view of a patient, and a second imaging device configured to generate a real-time thermal image of the first field of view. The system also includes a retaining structure, configured to be positioned in proximity to an eye of an operator, and a semitransparent screen configured to be mounted on the structure. The system additionally includes a processor configured to receive the images, and upon receiving an indication from the operator, to present, on the screen, the real-time visual image, or the real-time thermal image or the real-time thermal image overlaid on the real-time visual image, focused to a point in proximity to a near point of the eye while the operator can view, through the screen, a second field of view different from the first field of view.
