Preformed Orbita Implant with Breaking Lines
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current surgical implants for orbita fractures, such as meshes or plates, are difficult to manually shape to accurately replicate anatomical structures, leading to potential misalignments and vision disturbances if not properly reconstructed, and excessive manipulation can result in sight loss.
Innovation Solution
A preformed, three-segment implant with a first segment for the orbita bottom, a second segment for the medial wall, and a third segment for attachment at the latero-caudale orbita edge, allowing precise fitting and adjustable depth, with preset breaking lines for easy modification and safe insertion, reducing the need for manual adaptation by the surgeon.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If flat meshes or plates are used for orbita reconstruction, then the implant is easy to manufacture and store, but the surgeon must manually fold and bend them intraoperatively which increases surgical complexity and risk
Solution Approach 1:
The implant is preformed outside the body to match the complex anatomy of the orbita bottom and medial wall, including pre-formed breaking lines for depth adjustment. This preliminary shaping eliminates the need for intraoperative folding and bending, reducing surgical complexity while maintaining manufacturing ease through standardized preforming processes
Solution Approach 2:
The implant is divided into multiple segments separated by preset breaking lines, allowing the surgeon to adjust the depth and configuration intraoperatively by breaking along these lines. This segmentation provides flexibility for depth adjustment while the overall preformed shape maintains anatomical accuracy
2Adaptability or versatility
If the surgeon manually shapes the implant intraoperatively, then some anatomical structures can be adapted, but the result strongly depends on surgeon experience and deeper structures cannot be clearly defined
Solution Approach 1:
The implant is preformed with high precision to match the complex anatomy of the orbita bottom and medial wall, including the floor and the lateral orbital wall. This preliminary precise shaping ensures accurate reproduction of anatomical structures without relying on surgeon skill, while still allowing depth adjustment through preset breaking lines
3Ease of operation
If excessive manipulation is performed on the eye during operation, then the implant can be adjusted to fit, but the risk of sight loss increases
Solution Approach 1:
The implant is preformed with the correct anatomical shape and includes preset breaking lines that allow minimal intraoperative manipulation for depth adjustment. This reduces the number of times the implant needs to be inserted and manipulated, thereby minimizing the risk of damage to the eye and optical nerve
Solution Approach 2:
The preset breaking lines are strategically positioned to allow depth adjustment without requiring manipulation of the entire implant. This localized adjustability minimizes handling of the implant near the eye, reducing surgical risk while maintaining ease of operation

AI summary
The implant according to the invention is intended to be used as a replacement for an orbita bottom and optionally also for the medial orbita wall. The implant comprises the form of a single-piece preformed plate or grid which comprises a first segment, a second segment and a third segment. The first segment is designed in accordance with the form of the orbita bottom and the second segment is designed according to the form of the medial side-wall. The first and second segments adjoin each other along a first preset breaking line. The third segment adjoins the first segment and is arranged for fixing the implant to the lateral orbita edge.
