Surgical Site Mapping for Microscope Orientation and Navigation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing surgical microscopes require frequent adjustments for changing the field of view, zoom, and focus, which can disrupt the surgeon's orientation and efficiency during operations, and post-operative video playback is not intuitive for training and education.
Innovation Solution
A surgical imaging device that acquires and stitches multiple images to create a map of the surgical site, allowing real-time updates and additions of unmapped regions, different resolutions, or focus positions, and provides navigational aids like markers and labels to enhance orientation and playback functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the microscope position, zoom, and focus are frequently adjusted to view different areas of the surgical field, then the surgeon can observe different regions, but the procedural time increases and efficiency decreases
Solution Approach 1:
The system performs preliminary actions by automatically capturing images and generating a comprehensive surgical site map before the surgeon needs to navigate to different areas. The map is pre-computed with multiple views and orientations, allowing the surgeon to quickly jump to any region without manual microscope adjustments during the procedure.
Solution Approach 2:
The system creates a digital copy of the entire surgical field as a navigable map that replicates the physical surgical site's geometry and features. This virtual map serves as a surrogate for the actual surgical field, allowing surgeons to orient themselves and navigate to different areas by selecting locations on the map rather than physically moving the microscope.
2Measurement precision
If the microscope field of view is limited to provide magnified view, then detailed visualization is achieved, but the surgeon loses overall orientation of the surgical site
Solution Approach 1:
The system adds a spatial dimension by creating an overhead or panoramic map view that displays the entire surgical site layout. This map dimension provides contextual orientation showing where the current magnified view fits within the larger surgical field, allowing surgeons to maintain both detailed view and overall spatial awareness simultaneously.
Solution Approach 2:
The system implements a nested display structure where the magnified real-time microscope view is nested within or alongside the broader surgical site map. The map contains multiple levels of detail, with the current field of view highlighted and contextual landmarks visible, creating a nested information hierarchy that preserves both detail and orientation.
3Adaptability or versatility
If manual navigation and adjustments are required to access different surgical areas, then the surgeon can adapt the view, but the complexity of operation increases and efficiency decreases
Solution Approach 1:
The system performs self-service by automatically capturing images, processing them into a navigable map, and updating the display in real-time without requiring manual intervention from the surgeon. The system autonomously tracks surgical progress and regenerates the map as new areas are exposed, freeing the surgeon from navigation tasks.
Solution Approach 2:
The system replaces the mechanical manual adjustment of the microscope with an automated computational system. Instead of physically moving the microscope and manually focusing, the surgeon interacts with the digital map interface, and the system automatically adjusts the view by selecting and displaying the appropriate captured images and generating updated maps.
