Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current surgical methods for spine surgery lack accurate real-time assessment of vertebral alignment and load distribution, making it difficult to determine optimal placement and sizing of spinal implants, which can lead to suboptimal fusion and prolonged recovery.
Innovation Solution
A spine measurement system with a spinal instrument equipped with sensors and alignment circuitry that measures load, balance, and alignment, providing real-time data on force, pressure, orientation, and edge loading, and a graphical user interface for visual guidance on optimal prosthetic size and placement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional surgical methods are used for spine surgery, then the surgical procedure can be performed, but accurate real-time assessment of vertebral alignment and load distribution cannot be obtained
Solution Approach 1:
The patent replaces traditional mechanical surgical tools with an instrumented tool that incorporates electronic sensors and circuitry. The alignment circuitry with accelerometers and the load sensor replace conventional mechanical alignment methods, enabling electronic detection and measurement of vertebral alignment and load distribution in real-time during the surgical procedure.
Solution Approach 2:
The instrumented tool serves as an intermediary device between the surgeon and the vertebral structures. It includes a sensored head that interfaces with the vertebrae, containing load sensors that measure forces applied to the vertebrae during surgery, and alignment circuitry that provides positional information about the tool's orientation and location relative to the vertebral column.
2Manufacturing precision
If spinal implants are placed without real-time data, then the surgery can be completed quickly, but optimal placement and sizing cannot be determined
Solution Approach 1:
The system provides real-time feedback to the surgeon during the surgical procedure. The alignment circuitry continuously monitors the position and orientation of the instrumented tool relative to the vertebral column, and the load sensors provide feedback on the forces applied to the vertebrae. This feedback is displayed on a user interface, allowing the surgeon to make precise adjustments to achieve optimal implant placement and sizing.
Solution Approach 2:
The alignment circuitry and sensors are integrated into the instrumented tool before the surgical procedure begins. The system is pre-configured with alignment algorithms and measurement capabilities, allowing the surgeon to perform precise measurements and assessments during the surgery without requiring separate preliminary steps or additional equipment setup.
3Reliability
If traditional methods are used, then the surgical procedure is simple, but fusion outcomes are suboptimal and recovery is prolonged
Solution Approach 1:
The instrumented tool is designed as a multi-functional device that combines several capabilities in one tool. It includes alignment circuitry for positional assessment, load sensors for force measurement, and a user interface for data display. This universal tool can perform multiple functions including measuring vertebral alignment, assessing load distribution, and guiding implant placement, replacing the need for multiple separate surgical tools and assessment methods.
