Modular External Bone Fixator for Fracture Stabilization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current external orthopedic fixation devices are inadequate for treating fractures, particularly in conflict zones, as they are often heavy, uncomfortable, and scarce, leading to prolonged recovery times and limited treatment options, with a need for devices that are lighter, more versatile, and cost-effective.
Innovation Solution
A novel external bone fixator apparatus featuring adjustable arch-shaped support members with wire retainers and strut-rod assemblies that allow for precise positioning and adjustment of Kirschner wires to stabilize fractures, incorporating a method for compression, distraction, flexion, retraction, and rotational adjustments to facilitate healing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional external fixation devices are used, then fracture stabilization is achieved, but the devices are heavy and uncomfortable for patients
Solution Approach 1:
The fixation device is divided into multiple modular components including arch-shaped support members, wire retainers, and connection elements. This segmentation allows the device to maintain structural integrity for fracture stabilization while reducing overall weight through optimized component design and selective material usage.
Solution Approach 2:
Different portions of the device utilize different material properties and structural characteristics. The arch-shaped support members use high-strength materials localized at critical stress points, while other portions use lighter materials, achieving weight reduction without compromising fracture stabilization capability.
2Reliability
If traditional external fixation devices are used, then fracture stabilization is achieved, but treatment options are limited and recovery time is prolonged
Solution Approach 1:
The device incorporates universal wire retainers that can accommodate different wire configurations and attachment methods. The arch-shaped support members can be positioned and oriented to address various fracture patterns, and the modular design allows adaptation to different anatomical sites, providing multiple treatment options within a single device system.
Solution Approach 2:
The device allows dynamic adjustment of wire tension, arch positioning, and component configuration during treatment. This dynamic capability enables adaptation to changing patient needs and fracture healing progress, extending treatment options beyond static fixation approaches.
3Reliability
If traditional external fixation devices are used, then fracture stabilization is achieved, but the devices are scarce and costly in conflict zones
Solution Approach 1:
The modular segmented design allows individual components to be manufactured separately using simpler, more cost-effective processes. This segmentation enables local manufacturing in resource-limited settings while maintaining the reliability of the complete assembly for fracture stabilization.
Solution Approach 2:
Certain components of the device are designed to be inexpensive and potentially disposable, reducing the need for complex sterilization and maintenance infrastructure. This approach lowers overall cost and improves availability in conflict zones where medical resources are scarce.
