Radiolucent Pelvic Reduction Scaffold for Multi-Planar Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for stabilizing and reducing pelvic ring fractures are inadequate, as they often require substantial manual pressure and multi-planar corrections, which can lead to complications such as blood loss and nerve or vessel injury due to errant screw placement, and existing fracture tables do not allow for sufficient multi-planar alignment.
Innovation Solution
A radiolucent pelvic reduction system consisting of semi-circular rings and crossbars made of carbon fiber, which are clamped to an operating table to form a rigid scaffold for non-powered skeletal traction, enabling multi-planar alignment and stabilization of fractured bones with reduced soft tissue dissection and wound complications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If manual traction and multi-planar corrections are used to achieve fracture reduction, then alignment precision is improved, but the risk of nerve or vessel injury increases due to errant screw placement
Solution Approach 1:
The patent introduces a radiolucent scaffold as an intermediary device between the surgeon and the bone. This scaffold provides a stable anchoring point for reduction instruments and guide wires, enabling precise multi-planar alignment while reducing the risk of errant screw placement by establishing a controlled reference framework during the surgical procedure
Solution Approach 2:
The patent replaces traditional metal surgical instruments with radiolucent materials (carbon fiber) that are invisible on fluoroscopy. This substitution allows real-time visualization of bone anatomy and implant placement without interference from the reduction device, improving alignment precision while reducing harmful effects from metal instrumentation
2Force
If traditional metal surgical instruments are used for fracture reduction, then force application is effective, but blood loss and wound complications increase
Solution Approach 1:
The patent changes the material parameter of the reduction device from metal to radiolucent materials (carbon fiber). This parameter change maintains the structural integrity and force application capability while eliminating the harmful effects of metal instrumentation such as blood loss and wound complications, allowing for softer tissue interaction and reduced trauma
3Measurement precision
If fluoroscopy is used to guide screw placement, then placement accuracy is improved, but the complexity of the surgical system increases
Solution Approach 1:
The radiolucent scaffold serves multiple functions simultaneously: it provides structural support for instrument attachment, establishes alignment references, and acts as a fluoroscopy-transparent framework. This multi-functionality reduces the need for separate guidance systems and instruments, simplifying the overall surgical system while maintaining high placement accuracy through fluoroscopic guidance
