Apertured Prosthesis Patches for Implant Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing prostheses face challenges in providing reliable and rapid information to surgeons for precise implantation without compromising cell colonization or causing fabric distortions, as current methods like colored ink or embroidery are either harmful to cell recolonization or time-consuming and distortive.
Innovation Solution
A prosthesis with an apertured surface and biocompatible patches of different colors, featuring barbs that grip onto the fabric to provide information without affecting cell recolonization or distorting the fabric, allowing for easy and rapid production and visibility during implantation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If coloured ink is deposited directly on the yarns to provide information means, then the visibility of information is improved, but cell colonization is hindered at the ink-covered points
Solution Approach 1:
The information means are segmented into separate coloured patches that are applied only at specific locations on the prosthesis rather than coloring the entire fabric. This segmentation allows the majority of the prosthesis surface to remain free of harmful substances, preserving cell colonization capability while providing visible information at critical positioning points.
Solution Approach 2:
Coloured patches serve as intermediary elements that carry the information without directly contacting the tissue. These patches are applied to the prosthesis surface and provide visual guidance to the surgeon without the harmful effects of ink deposition on the base fabric, thus mediating between the need for information visibility and the need for biocompatibility.
2Reliability
If embroidery is added to provide information means, then the visibility and reliability of information is improved, but the production time increases and fabric distortions occur
Solution Approach 1:
The information provision is segmented into separate, pre-manufactured coloured patches rather than integrating information means directly into the fabric through embroidery. This allows the patches to be prepared independently and attached rapidly to the prosthesis, significantly reducing production time while maintaining reliable visual information.
Solution Approach 2:
The coloured patches are prepared in advance as separate components with their information patterns already established during patch manufacturing. This preliminary action eliminates the need for time-consuming embroidery work during prosthesis production, as the patches can be simply attached to the finished prosthesis.
3Loss of information
If embroidery is added to provide information means, then the visibility of information is improved, but fabric distortions and excess neofibrosis occur
Solution Approach 1:
The information means are segmented into separate coloured patches applied to the prosthesis surface rather than being integrated through embroidery that distorts the fabric structure. This segmentation preserves the original fabric integrity and avoids the mechanical stress and distortion caused by embroidery threads.
Solution Approach 2:
The coloured patches act as intermediary elements that provide visual information without requiring direct integration with the fabric structure. This eliminates the need for embroidery that causes fabric distortion and the subsequent excessive neofibrosis response, as the patches can be attached superficially without penetrating or distorting the base fabric.
