Problem
Existing external fixation devices lack versatility in pin placement, are complex to use, and are not cost-effective, making them inadequate for a wide range of bone injuries, particularly in the upper and lower extremities.
Innovation Solution
A modular external fixation device with adjustable clamp systems and rails that allow for multi-planar and multi-joint correction, enabling versatile pin placement without disturbing existing pins, and incorporating compression and distraction nuts for precise bone manipulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing external fixation devices are used, then bone stabilization is achieved, but versatility in pin placement is limited
Solution Approach 1:
The external fixation device is divided into modular components including multiple rails, clamps, and pins that can be independently positioned and configured. Each rail can accommodate pins at various locations and angles, allowing customized pin placement patterns while maintaining overall system stability for effective bone fixation.
2Ease of operation
If existing external fixation devices provide stable fixation, then bone injury treatment is effective, but device complexity increases
Solution Approach 1:
The device employs universal components such as standardized rails with multiple attachment points and adjustable clamps that can accommodate different pin configurations for various bone injuries. This multi-functionality allows a single device design to handle diverse clinical scenarios without requiring multiple specialized devices, reducing overall system complexity while maintaining versatility.
3Ease of manufacture
If existing external fixation devices are used, then bone stabilization is achieved, but cost-effectiveness decreases
Solution Approach 1:
The external fixation device incorporates dynamic adjustment capabilities allowing clinicians to modify pin positions, rail orientations, and clamp configurations as the bone heals and treatment requirements change. This adaptability extends the device's useful life and treatment effectiveness across different healing stages, improving cost-effectiveness by eliminating the need for multiple device replacements.
