Surgical Navigation Probe Pose Detection and Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current surgical navigation systems have limited ability to virtually plan and prepare for the placement of tools and implants, especially for subcutaneous locations inaccessible without an incision or burr hole, and struggle with precise tracking and storage of specific virtual locations within a 3D anatomical volume.
Innovation Solution
The system employs anatomical imaging information and a tracking system to detect the pose of a probe, identify locations within a 3D anatomical volume, and store these locations using a processor and memory, allowing for precise tracking and planning of surgical instruments and implants without direct physical access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If surgical navigation systems use tracking systems to monitor probe position, then the ability to track and guide surgical instruments is improved, but the ability to plan and prepare for placement of tools and implants in subcutaneous locations remains limited
Solution Approach 1:
The system performs preliminary action by allowing surgeons to plan and prepare surgical procedures virtually before actual surgery. The system stores 3D anatomical information and enables virtual placement of tools and implants, allowing surgeons to rehearse and optimize surgical approaches without making actual incisions or accessing subcutaneous locations physically.
Solution Approach 2:
The system creates a virtual copy of the patient's 3D anatomical structure using imaging data. This digital replica allows surgeons to interact with and plan procedures on a virtual model, which can be manipulated and explored without risking harm to the actual patient. The virtual model preserves all critical anatomical relationships and measurements.
2Measurement precision
If the system stores specific virtual locations in 3D anatomical volume, then the precision of location identification is improved, but the complexity of the system increases
Solution Approach 1:
The system replaces complex mechanical tracking and measurement systems with a computational approach. Instead of using intricate mechanical devices to physically measure and mark locations, the system uses 3D imaging data and computational algorithms to identify, store, and retrieve virtual locations with high precision. This substitution of mechanical systems with information processing simplifies the overall system architecture.
3Productivity
If the system allows virtual planning without physical access, then the need for manual intervention is reduced, but the ability to confirm actual placement accuracy may be compromised
Solution Approach 1:
The system implements feedback by continuously monitoring the actual position of surgical instruments during procedures and comparing it with the pre-planned virtual locations. The tracking system provides real-time feedback on instrument position, allowing surgeons to verify that actual placements match the virtual plan. This closed-loop feedback ensures placement accuracy while maintaining surgical efficiency.
