Movable Bone Plate System for Controlled Compression
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current bone and joint compression methods relying on screws and ramped compression holes are insufficient when bone quality is poor, leading to inadequate compression forces.
Innovation Solution
A movable bone plate implantation system comprising a movement instrument, a translation member, and a bone plate, which allows for controlled movement and alignment of bones using a method that includes aligning the bone plate, inserting fasteners, and utilizing a temporary fixation pin to achieve compression or distraction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If screws and ramped compression holes are used for bone compression, then the compression method is simple and widely applicable, but the compression force becomes insufficient when bone quality is poor
Solution Approach 1:
The bone plate is designed with a movable portion that can dynamically adjust its position relative to the fixed portion. This dynamic mechanism allows the plate to adapt to varying bone qualities and apply optimal compression force regardless of whether the bone is of poor quality, thereby resolving the contradiction between method simplicity and compression force effectiveness
Solution Approach 2:
The system changes the mechanical parameters of the compression application by introducing a movable bone plate with adjustable positioning capabilities. This allows modification of the compression force parameters based on bone quality, enabling sufficient compression force to be applied even when bone quality is poor, while maintaining operational simplicity
2Reliability
If bone quality decreases, then the bone becomes more vulnerable to compression failures, but the compression force application becomes more difficult
Solution Approach 1:
The movable bone plate system incorporates feedback mechanisms that allow real-time adjustment of the compression application based on bone response. This feedback enables the system to adapt to poor bone quality conditions and maintain reliable compression force application, making the procedure easier to perform despite varying bone qualities
Solution Approach 2:
The dynamic nature of the movable bone plate allows it to respond to and adapt to poor bone quality conditions during the compression procedure. This dynamic adjustment capability ensures reliable compression force application while simplifying the surgical operation, as the system automatically adjusts to accommodate poor bone quality without requiring complex manual intervention
