Adjustable Titanium Orthognathic Plates for Minimally Invasive Surgery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing orthognathic surgical plates are large, non-anatomical, and require manual shaping, leading to increased surgical trauma, longer procedure and recovery times, and higher risks of infection and blood loss.
Innovation Solution
Development of adjustable plates made of pure titanium with pre-molded, anatomical designs, low profile, and a rigid fixation system, featuring reduced designs, angled posterior holes, and restructured central regions, designed for minimally invasive orthognathic surgery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If traditional large non-anatomical plates are used, then fixation strength is ensured, but surgical trauma increases and recovery time lengthens
Solution Approach 1:
The plate design incorporates varying thicknesses and densities in different regions to match the local anatomical requirements of the jawbone. The anatomical contouring provides optimal contact and distribution of forces at specific locations while maintaining overall strength, reducing the need for excessive material throughout the entire plate structure.
Solution Approach 2:
The plate is divided into multiple sections with different functional zones - some areas provide rigid fixation while others offer flexibility or anatomical adaptation. The segmented design allows each portion to be optimized for its specific location and function, reducing overall trauma while maintaining necessary fixation strength.
2Stability of the object's composition
If traditional large non-anatomical plates are used, then fixation stability is achieved, but surgical procedure time increases
Solution Approach 1:
The plates are pre-contoured and pre-shaped to match the anatomical geometry of the jawbone before surgery. This preliminary preparation eliminates the need for time-consuming intraoperative bending and shaping, allowing surgeons to directly implant the plates while maintaining fixation stability.
3Strength
If traditional robust plate designs are used, then mechanical strength is ensured, but post-operative recovery time lengthens
Solution Approach 1:
The plate design optimizes parameters such as thickness, width, and material distribution to achieve the minimum necessary mechanical strength required for fixation. By adjusting these parameters to match actual clinical needs rather than using overly robust designs, the biological response is improved and recovery time is reduced while maintaining adequate mechanical support.
4Adaptability or versatility
If traditional non-anatomical plates requiring manual shaping are used, then adaptability to patient anatomy is achieved, but surgical complexity increases
Solution Approach 1:
The plates are manufactured with pre-contoured anatomical shapes that match the natural geometry of the jawbone. This preliminary action of pre-shaping eliminates the need for complex intraoperative bending and adaptation procedures, reducing surgical complexity while maintaining excellent anatomical fit and adaptability.
