Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If current surgical imaging and navigation hardware and software are used, then basic imaging functionality is provided, but robust procedure guidance for both hard and soft tissues is not achieved
Solution Approach 1:
The system integrates multiple imaging modalities (3D scanning, intraoperative imaging, augmented reality) into a single platform that can handle both hard tissue (bone) and soft tissue imaging, making the system universally applicable across different surgical applications and tissue types
2Measurement precision
If a system combines augmented reality, real time imaging, procedure guidance, and decision support, then surgical precision and navigation are enhanced, but device complexity increases
Solution Approach 1:
The patent merges multiple previously separate systems (3D scanning, intraoperative imaging, augmented reality display, tracking hardware) into an integrated surgical imaging and navigation system, reducing the number of separate devices surgeons must manage while maintaining high precision capabilities
Solution Approach 2:
The system introduces a control computing device as an intermediary that coordinates and integrates data from multiple imaging modalities and processing algorithms, managing system complexity centrally rather than requiring direct integration between all components
3Measurement precision
If 3D scanning and intraoperative imaging are integrated with tracking and image processing, then accurate real-time guidance is provided, but processing time and computational requirements increase
Solution Approach 1:
The system performs preliminary 3D scanning and image processing before surgery begins, creating pre-processed datasets and registration information that can be quickly accessed and updated during surgery, reducing real-time processing requirements

AI summary
A system for executing a three-dimensional (3D) intraoperative scan of a patient is disclosed. A 3D scanner control computing device projects the object points included onto a first image plane and the object points onto a second image plane. The 3D scanner control computing device determines first epipolar lines associated with the first image plane and second epipolar lines associated with the second image plane based on an epipolar plane that triangulates the object points included in the first 2D intraoperative image to the object points included in the second 2D intraoperative image. Each epipolar lines provides a depth of each object as projected onto the first image plane and the second image plane. The 3D scanner control computing device converts the first 2D intraoperative image and the second 2D intraoperative image to the 3D intraoperative scan of the patient based on the depth of each object point provided by each corresponding epipolar line.
