Extremity Bone Fixation Implant With Adjustable Joint Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional bone fixation implants lack flexibility and require multiple components with intricate mating features, leading to increased costs and less desirable healing outcomes, especially for smaller bones.
Innovation Solution
A bone fixation system with a bone implant and internal implant core that allows for adjustable alignment of bone segments using a flexible elongated element, along with joint preparation jigs and fixation plates for secure attachment, enabling less invasive procedures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If conventional bone fixation implants use generic screws and wires to create rigidly fused joints, then structural stability is improved, but adaptability and ease of intraoperative adjustment deteriorate
Solution Approach 1:
The bone fixation implant incorporates a dynamic adjustment mechanism that allows the angle between the first and second bone segments to be modified intraoperatively. The implant includes adjustable components with movable joints that enable real-time reconfiguration of the fixation angle without requiring additional surgical procedures or component replacements.
Solution Approach 2:
The implant is divided into multiple separable components including a first segment for engaging the first bone, a second segment for engaging the second bone, and an adjustable connection element between them. This segmentation allows independent positioning and angulation of each segment while maintaining overall structural integrity.
2Adaptability or versatility
If bone fixation implants offer limited flexibility for specific circumstances, then adaptability is improved, but device complexity and surgical procedure difficulty increase
Solution Approach 1:
The implant design provides multiple adjustment capabilities within a single device structure, allowing it to accommodate various bone configurations, angles, and patient anatomies without requiring multiple specialized implants. The universal design includes adjustable angulation, position, and orientation features that can be configured for different surgical scenarios.
Solution Approach 2:
Multiple adjustment functions are integrated into a single implant component rather than requiring separate adjustment mechanisms. The implant combines angular adjustment, positional adjustment, and fixation capabilities in one unified structure, reducing the number of parts and simplifying the surgical procedure.
3Adaptability or versatility
If multiple components with intricate mating features are used for customization, then adaptability is improved, but manufacturing cost and device complexity increase
Solution Approach 1:
The implant achieves customization through adjustable parameters such as angulation, position, and orientation that can be modified intraoperatively rather than requiring custom-manufactured components for each patient. The device includes adjustable elements that allow surgeons to optimize the fixation configuration based on patient-specific anatomy without increasing manufacturing complexity.
