Spinal Implant Detection Device Tension Release
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current surgical treatments for spinal disorders often require invasive procedures and can lead to over-correction or excessive tension in implanted correction systems, which may result in undesirable tissue damage and cosmetic or functional impairments.
Innovation Solution
A spinal implant detection device with a detectable marker and tether release system that allows for minimally invasive manipulation and tension adjustment of implanted longitudinal elements, such as tethers, using a posterior surgical approach and image guidance to avoid excessive correction and tissue disruption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional surgical treatments are used for spinal disorders, then correction and stabilization can be achieved, but invasive procedures and tissue damage increase
Solution Approach 1:
The patent replaces traditional open surgical mechanical manipulation with image-guided percutaneous instrumentation. The surgical system uses fluoroscopic or CT imaging guidance to navigate and position implants through small incisions, substituting direct visual mechanical exploration with imaging-based mechanical placement, thereby reducing tissue disruption while maintaining correction effectiveness
Solution Approach 2:
The patent introduces image guidance systems as an intermediary between the surgeon and the surgical field. Imaging technology serves as a mediator that provides real-time visualization of implant positioning and spinal anatomy, enabling precise placement without extensive tissue dissection, thus reducing harmful mechanical trauma while achieving reliable correction
2Stability of the object's composition
If traditional correction systems are implanted, then spinal stabilization is achieved, but over-correction and excessive tension may occur
Solution Approach 1:
The patent employs image guidance systems that provide real-time feedback during implant placement and tether tensioning. The imaging system allows surgeons to monitor spinal alignment and implant positioning continuously, enabling adjustments to prevent over-correction while achieving adequate stabilization, thus eliminating the harmful effect of excessive tension
Solution Approach 2:
The patent introduces adjustable tether tensioning mechanisms that allow dynamic modification of correction forces after initial implantation. The system enables progressive tensioning and adjustment based on observed spinal alignment, transitioning from static to dynamic control to prevent over-correction while maintaining necessary stabilization
3Measurement precision
If detectable markers are added to implants, then manipulation and detection precision improve, but device complexity increases
Solution Approach 1:
The patent incorporates radiopaque markers on implant components that appear as distinct radiographic signatures on fluoroscopic or CT images. These markers provide high-contrast visual indicators that enhance detection precision and positioning accuracy without adding mechanical complexity to the implant structure, as the markers are integrated into existing components
