Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for stabilizing mammalian bony segments using elongated elements are complex and involve temporary constructs like guide wires and fixation pins, which complicate the fixation architecture and procedures for implantation.
Innovation Solution
A bony segment fixation system with a planar fixation element and retention modules that include fenestrations and serrations, allowing for secure engagement and stabilization of bony segments, along with a simplified procedure using guide wires and fixation pins to prevent dislocation and ensure optimal placement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional temporary constructs like guide wires and fixation pins are used for stabilization, then bony segments can be stabilized, but the fixation architecture and implantation procedures become complex
Solution Approach 1:
The patent combines the temporary guide wire function and permanent fixation element function into a single integrated temporary fixation element. This element serves both as a guide for placement and as the final stabilizing component, eliminating the need for separate guide wires and fixation pins, thereby reducing architectural complexity while maintaining stabilization reliability
Solution Approach 2:
The temporary fixation element is designed to perform multiple functions: it acts as a guide wire during insertion, provides temporary stabilization during implantation, and serves as the permanent fixation element after implantation. This multi-functionality reduces the number of components needed and simplifies the overall fixation architecture
2Reliability
If traditional temporary constructs are used, then bony segments can be stabilized, but the implantation procedures become complex
Solution Approach 1:
By merging the guide wire and fixation pin into a single temporary fixation element, the implantation procedure is simplified. The surgeon only needs to insert one element instead of coordinating multiple separate components, reducing procedural complexity while ensuring reliable stabilization
Solution Approach 2:
The temporary fixation element is designed with pre-formed geometric features (such as curved shapes or angled configurations) that are predetermined to match the anatomical geometry of the bony segments. This preliminary configuration allows for easier insertion and proper positioning without requiring complex intraoperative adjustments
3Reliability
If retention modules with fenestrations and serrations are used, then secure engagement is achieved, but the device structure becomes more complex
Solution Approach 1:
The retention module incorporates fenestrations and serrations only at specific localized areas where engagement with the bony segments is required. The rest of the structure remains simple and streamlined. This localized application of complex features provides secure engagement where needed without unnecessarily increasing overall device complexity
