Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current orthopedic diagnostic methods are limited in detecting and addressing spinal joint issues, particularly in determining the target geometry for spinal surgery and projecting loads across spinal orthopedic implants, which affects the accuracy and effectiveness of spinal surgery.
Innovation Solution
A system that uses medical images to generate optimized anatomical datasets for spinal surgery, including target disc height, anterior-posterior offset, and lordosis angle, and projects estimated weights and loads onto spinal joints, providing real-time feedback during surgery to ensure accurate implant placement and alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If current orthopedic diagnostic methods (X-Rays, MRI, physical exams) are used, then the diagnostic process is simple and widely available, but the ability to detect and address spinal joint issues is limited
Solution Approach 1:
The patent combines multiple diagnostic modalities (X-Rays, MRI, physical exams) into a unified navigation system that integrates pre-operative imaging data with intra-operative visualization, creating a comprehensive diagnostic platform that overcomes the limitations of individual methods
Solution Approach 2:
The navigation system acts as an intermediary between traditional diagnostic methods and surgical decision-making, processing and synthesizing data from various sources to provide enhanced diagnostic capabilities without requiring surgeons to directly manage complex individual imaging systems
2Manufacturing precision
If traditional surgical planning methods are used, then the surgical process is straightforward, but the accuracy of target geometry determination is insufficient
Solution Approach 1:
The system performs preliminary surgical planning and target geometry determination before surgery using pre-operative imaging data, allowing surgeons to review and adjust plans in advance while maintaining the ability to refine targets intra-operatively based on real-time feedback
Solution Approach 2:
The navigation system provides continuous feedback during surgery by comparing actual anatomical structures with pre-planned targets, enabling real-time adjustments to maintain high precision without excessively extending surgical time
3Measurement precision
If detailed anatomical analysis is performed on all spine levels, then the accuracy of target geometry determination is improved, but the processing time and complexity increase
Solution Approach 1:
The system applies different levels of analysis to different spinal levels based on surgical relevance, performing detailed anatomical measurements only on levels requiring intervention while using streamlined assessment for other levels, optimizing the balance between precision and efficiency
