Structured Light Camera Guidance for Dynamic Surgical Anatomy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Surgical guidance systems face challenges in accurately translating pre-operative planning into the intraoperative phase, particularly in intricate procedures like neurosurgery, due to the difficulty in maintaining spatial awareness of critical structures and adapting to real-time anatomical changes.
Innovation Solution
A surgical guidance system integrating a three-dimensional camera, structured light projector, and computation module that generates a dynamic, interactive three-dimensional model of the surgical target area, projecting real-time visual aids such as entry points, safety zones, and anatomical atlases directly onto the patient's body, adapting to movements and changes in anatomy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If pre-operative medical imaging data is used to generate surgical guidance shapes, then surgical planning accuracy is improved, but the system cannot adapt to real-time anatomical changes during the procedure
Solution Approach 1:
The system transitions from static pre-operative imaging to dynamic real-time 3D capture. The 3D camera continuously captures anatomical changes during surgery, and the computational module dynamically updates the 3D model and adjusts guidance shapes in real-time, allowing the system to adapt to anatomical variations while maintaining precision.
Solution Approach 2:
The system implements a feedback loop where the 3D camera captures real-time anatomical data, the computational module compares it with the pre-operative plan, and adjusts the guidance projections accordingly. This closed-loop feedback enables continuous adaptation to actual anatomical conditions while maintaining surgical planning accuracy.
2Adaptability or versatility
If a three-dimensional camera and structured light projector are integrated for real-time guidance, then adaptability to anatomical changes is improved, but device complexity increases
Solution Approach 1:
The system merges the 3D camera, structured light projector, and computational module into an integrated surgical guidance system. This consolidation reduces the number of separate devices needed, simplifies system integration, and enables seamless real-time guidance while maintaining adaptability to anatomical changes.
Solution Approach 2:
The integrated system performs multiple functions: the 3D camera captures anatomical data, the computational module processes and generates guidance information, and the structured light projector displays real-time feedback. This multi-functionality reduces the need for multiple separate devices and simplifies the overall system while providing comprehensive real-time guidance.
3Ease of operation
If surgical guidance shapes are projected directly onto the patient, then spatial awareness is improved, but the system must account for surface irregularities and movements
Solution Approach 1:
The system creates a digital 3D copy of the patient's anatomy using the 3D camera and computational module. This virtual model is used to generate guidance shapes that automatically account for surface irregularities and movements, eliminating the need for direct physical measurement and simplifying spatial awareness while accurately compensating for anatomical variations.

AI summary
A method for providing surgical guidance can include: capturing, with a three-dimensional camera, a three-dimensional image of a surgical target area on a patient; generating, from pre-operative medical imaging data, a three-dimensional model of the surgical target area; adjusting a visual representation of surgical instructions based on the three-dimensional model to create an adjusted visual representation; and projecting, via a structured light projector, the adjusted visual representation onto the surgical target area to guide a medical professional during a surgical procedure.
