Zigzag Seam Prosthesis for Surgeon Guidance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing textile prostheses face challenges in providing reliable and quick information to surgeons for precise implantation without affecting the prosthesis's properties, such as elasticity and thickness, as existing methods like embroidery are tedious, distort the textile, and alter its essential properties.
Innovation Solution
A prosthesis with a zigzag seam incorporated into the textile, which traverses its thickness without altering its elasticity or porosity, serving as a means of information for the surgeon while maintaining the textile's initial thickness and properties.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If embroidery is used to provide information markers on the prosthesis, then the surgeon can be guided during implantation, but the textile's elasticity is blocked and its essential properties are altered
Solution Approach 1:
The seam is constructed with porous threads that maintain the textile's porosity and elasticity. The porous structure allows the textile to stretch and deform without the seam blocking the elasticity, while still providing visible information to the surgeon through the contrasting thread pattern.
Solution Approach 2:
The seam follows a curved or zigzag path rather than a straight line, which allows it to accommodate the elastic deformation of the textile. The curved configuration enables the seam to flex and stretch with the textile while maintaining structural integrity and visual visibility.
2Loss of information
If embroidery is applied to mark the prosthesis, then information can be provided to the surgeon, but the textile's thickness is changed making it unsuitable for certain applications
Solution Approach 1:
The seam follows a curved or zigzag path rather than a straight line, which allows it to accommodate the elastic deformation of the textile. The curved configuration enables the seam to flex and stretch with the textile while maintaining structural integrity and visual visibility.
Solution Approach 2:
The seam is designed to be minimally intrusive, with threads that match the textile's thickness profile. The stitching is configured to lie flat against the textile surface, providing local information marking without creating protruding excesses that would alter the overall thickness profile.
3Loss of information
If embroidery is used to provide markers, then the prosthesis can be oriented correctly, but the process is tedious and time-consuming
Solution Approach 1:
The information-providing seam is integrated into the prosthesis manufacturing process itself, rather than being added as a separate post-processing step. The seam is formed during textile production, allowing information markers to be created automatically as part of the base material fabrication, thereby eliminating tedious manual embroidery operations.
Solution Approach 2:
The seam serves dual functions: it provides structural reinforcement of the textile while simultaneously serving as the information-bearing element. This multi-functionality eliminates the need for separate embroidery operations, as the same stitching process that strengthens the textile also creates the visible markers for surgeon guidance.
