Current spinal surgery methods lack efficient systems for real-time intraoperative alignment and rod bending, leading to subjective and time-consuming procedures that can result in suboptimal spinal fixation and increased morbidity.
Innovation Solution
A system comprising an imaging device, spatial tracking system, and control unit with software for preoperative and intraoperative measurement input, generating rod bending instructions for precise alignment and correction of spinal parameters, including sagittal and coronal balance, to achieve global spinal alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If manual measurement and rod bending methods are used, then surgical flexibility is maintained, but procedural time increases and alignment precision deteriorates
Solution Approach 1:
The system performs preoperative planning and generates rod bending instructions before surgery. The rod bending instructions are based on patient-specific anatomical measurements and surgical goals, allowing the surgeon to execute precise bends during surgery without time-consuming intraoperative calculations or trial-and-error adjustments.
Solution Approach 2:
The patent replaces manual mechanical measurement and rod bending with an integrated system that uses imaging devices, spatial tracking, and computer-generated bending instructions. This substitution of mechanical processes with an automated system achieves higher precision while reducing procedural time.
2Manufacturing precision
If subjective rod bending methods are used, then device complexity is reduced, but manufacturing precision deteriorates
Solution Approach 1:
The patent replaces subjective mechanical rod bending with an automated system that uses imaging, spatial tracking, and computer algorithms to generate objective bending instructions. This eliminates surgeon subjectivity and variability, achieving consistent high-precision results.
Solution Approach 2:
The system creates a digital replica of the patient's spinal anatomy through imaging and spatial tracking. This digital model is used to generate accurate rod bending instructions that precisely match the patient's unique anatomy, eliminating the need for physical trial-and-error fitting.
3Measurement precision
If real-time intraoperative measurement is performed, then alignment precision improves, but device complexity increases
Solution Approach 1:
The system integrates multiple functions into a unified platform: preoperative planning, intraoperative imaging, spatial tracking, rod bending instruction generation, and assessment. This multi-functional integration allows real-time precise measurement while managing complexity through a single comprehensive system.
Solution Approach 2:
The system provides real-time feedback during surgery by comparing actual spinal parameters against the preoperative plan. This feedback loop allows the surgeon to make immediate adjustments to achieve the desired alignment, with the system automatically updating rod bending instructions based on measured parameters.
