Radiolucent Pelvic Reduction System Multi-Planar Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for stabilizing and reducing pelvic ring fractures are challenging due to the complexity of pelvic anatomy and the need for multi-planar alignment, which often results in substantial manual pressure, potential nerve or vessel injury, and inadequate alignment with uni-planar traction.
Innovation Solution
A radiolucent pelvic reduction system using semi-circular carbon fiber rings clamped to an operating table, allowing for multi-planar alignment and stabilization of fractured bones through adjustable crossbars, reducing the need for substantial manual traction and minimizing soft tissue dissection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If manual traction and uni-planar traction are used to achieve fracture reduction, then fracture alignment can be achieved, but the pressure required is substantial and may cause nerve or vessel injury
Solution Approach 1:
The patent transitions from uni-planar traction to multi-planar alignment by introducing a pelvic ring fixation device that applies forces in multiple planes simultaneously. The device includes superior and inferior fixation points connected by rods, allowing alignment in vertical, horizontal, and rotational planes, thereby achieving precise fracture reduction without requiring substantial manual traction pressure that could harm nerves or vessels.
2Manufacturing precision
If manual pressure is applied to correct fracture deformity, then fracture reduction can be achieved, but the force required is substantial due to deforming forces from major muscle groups
Solution Approach 1:
The patent introduces an intermediary mechanical system (the pelvic ring fixation device) between the surgeon and the bone. The device includes fixation pins inserted into the pelvic bones, connected by rods that form a rigid structure. This intermediary system allows the surgeon to apply controlled forces through the rod mechanism rather than applying substantial manual pressure directly to the bone, reducing the risk of muscle group counterforces and enabling precise fracture reduction with manageable forces.
3Reliability
If percutaneous screw fixation is used to stabilize pelvic ring disruptions, then definitive stabilization can be achieved, but the procedure requires multi-planar fluoroscopic imaging and skilled radiology technician coordination
Solution Approach 1:
The patent applies preliminary action by first establishing the pelvic ring fixation device with superior and inferior fixation points before performing definitive screw fixation. The multi-planar fluoroscopic imaging is used to guide the placement of the fixation pins and rods in advance, ensuring proper alignment and positioning. This preliminary stabilization structure is then in place to guide and facilitate the subsequent definitive screw fixation procedure, reducing the overall complexity and improving reliability.
4Manufacturing precision
If traditional skeletal traction is used to improve alignment, then alignment can be achieved, but the traction must be uni-planar longitudinal which is insufficient for perfect reduction
Solution Approach 1:
The patent fundamentally changes the traction approach by moving from uni-planar longitudinal traction to multi-planar alignment. The pelvic ring fixation device enables application of forces in superior-inferior, anterior-posterior, and rotational planes simultaneously. The rod structure connected to fixation pins allows adjustment and application of forces in multiple dimensions, providing versatile alignment capability that addresses complex pelvic fractures more effectively than traditional single-plane traction.
