Bone Plate With Transverse Slider Slots for Lateral Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bone plates for osteosynthesis offer limited adjustability, primarily allowing longitudinal and rotational positioning, but lack lateral adjustability, which restricts their temporary repositioning capabilities.
Innovation Solution
Incorporating a slider with a transverse slot on the bone plate that allows sliding along a longitudinal axis, enabling temporary repositioning laterally in addition to longitudinal and rotational adjustments, facilitated by a fastener system that allows for final securement after desired positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional bone plate design with only longitudinal slots is used, then the structure remains simple, but lateral adjustability is lost
Solution Approach 1:
The bone plate is segmented into multiple functional components: a plate body with longitudinal slots, and separate sliders with transverse slots that can be independently positioned. This segmentation allows each component to provide specific adjustment capabilities (longitudinal vs. lateral) while maintaining overall structural simplicity through modular assembly.
Solution Approach 2:
The invention adds lateral adjustability by introducing transverse slots perpendicular to the existing longitudinal slots. This creates a two-dimensional adjustment plane, allowing the bone plate to be repositioned not only along the longitudinal axis but also laterally, thereby expanding the adjustment versatility without fundamentally complicating the base structure.
2Adaptability or versatility
If multiple adjustment directions are added to the bone plate, then positioning flexibility improves, but the risk of improper fixation increases
Solution Approach 1:
The fastening system transitions from a static, fixed-position design to a dynamic, multi-stage adjustment mechanism. Sliders can be freely positioned within longitudinal slots during the adjustment phase, allowing flexible repositioning. Once the desired position is achieved, the fasteners are tightened to lock the sliders in place, providing stable fixation. This dynamic system accommodates both positioning flexibility and fixation stability.
Solution Approach 2:
The design allows preliminary positioning adjustments to be made before final fixation. Surgeons can temporarily position the bone plate and sliders in various configurations, test the fit and alignment, and make necessary adjustments before securing the fasteners. This preliminary action ensures optimal positioning while maintaining the ability to correct any improper fixation before commitment.
3Measurement precision
If transverse slots and sliders are added to enable lateral movement, then surgical accuracy improves, but the device complexity increases
Solution Approach 1:
The complex function of lateral and longitudinal adjustment is segmented into separate, simple components: sliders provide lateral movement through transverse slots, while the plate body provides longitudinal positioning through longitudinal slots. This segmentation allows each component to perform its specific function with simple geometry, avoiding the need for a single complex mechanism and thereby reducing overall device complexity while maintaining surgical accuracy.
