Notched Helix Bone Implant for Flexible, Stable Fixation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bone implants are rigid, limiting movement and prone to detachment, making it difficult for patients to move freely after surgery and increasing the risk of implant failure.
Innovation Solution
A flexible bone implant design featuring a helix body with pillars and notches that enhance structural strength and flexibility, allowing for reduced movement restriction and improved stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a rigid bone implant is used, then the implant maintains structural strength, but the movement of the injured portion is limited and the implant may break due to excessive movement
Solution Approach 1:
The bone implant is divided into multiple segments (first bone implant portion, second bone implant portion, and connecting portion) that can move relative to each other. The connecting portion includes a first connection element and a second connection element that allow controlled movement while maintaining overall structural integrity, resolving the contradiction between rigidity and movement freedom.
Solution Approach 2:
The implant transitions from a static rigid structure to a dynamic structure with movable connecting portions. The first and second connection elements can rotate and move relative to each other, allowing the implant to adapt to natural bone movement while maintaining strength, thus resolving the contradiction between structural strength and movement freedom.
2Reliability
If a rigid bone implant is used, then the implant provides stable fixation, but the implant may be accidentally detached due to movement limitations
Solution Approach 1:
The implant is segmented into multiple portions with connection elements that allow controlled movement. This segmentation enables the implant to maintain stable fixation through the helical screw structure while allowing natural bone movement through the flexible connecting portions, preventing accidental detachment.
Solution Approach 2:
The implant changes its structural parameters by allowing relative movement between connection elements. The first and second connection elements can change their relative positions and orientations, enabling the implant to maintain fixation stability while adapting to movement, thus preventing detachment.
3Ease of operation
If the bone implant allows movement, then movement freedom is improved, but the structural strength may be compromised
Solution Approach 1:
The implant divides the structure into strong fixed portions (helical screw parts embedded in bone) and flexible connecting portions. The first and second bone implant portions provide anchoring strength while the connecting portion allows movement, maintaining overall structural strength while enabling movement freedom.
Solution Approach 2:
The implant uses dynamic connection elements that can move and rotate relative to each other. The first connection element and second connection element maintain structural strength through their connection structure while allowing controlled movement, resolving the contradiction between strength and movement freedom.
