Segmented Mesh Strip for Even Tension Distribution in Tissue Lifting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current minimally invasive procedures for facial and body tissue lifting, such as thread lifts, face limited in longevity and often result in irregularities like 'cheese wiring' due to concentrated tension points, lacking effective distribution of tension across tissue anchoring sites.
Innovation Solution
Development of mesh strips or cords with anchors like barbs, hooks, or cones made of absorbable or non-absorbable materials, introduced via an introducer device, which self-expand to distribute tension evenly across tissue layers, reducing puckering and enhancing lift longevity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If thread lifts are used for minimally invasive facial lifting, then the procedure is less invasive, but the longevity is limited and irregularities occur
Solution Approach 1:
The lifting device is segmented into multiple anchoring points along its length, allowing tension to be distributed across multiple tissue attachment sites rather than concentrated at single points. This segmentation enables the device to maintain lifting effect longer while reducing tissue damage and irregularities.
Solution Approach 2:
The invention transitions from traditional single-point or limited-point anchoring to multi-point anchoring along the length of the lifting device. This dimensional expansion of anchoring points creates a more distributed tension system that improves both longevity and reduces harmful concentration effects.
2Device complexity
If traditional lifting devices are used, then the procedure is simple, but tension is concentrated at anchor points causing irregularities like cheese wiring
Solution Approach 1:
The lifting device incorporates multiple anchoring points segmented along its structure, transforming the tension distribution from concentrated to distributed. This segmentation maintains relative device simplicity while eliminating the cheese wiring effect caused by single-point tension concentration.
3Ease of operation
If fewer anchoring points are used, then the device is simpler to insert, but tension distribution is poor leading to irregularities
Solution Approach 1:
The device features multiple anchoring points segmented along its length, which can be inserted through a single minimally invasive access point while providing distributed tension. This segmentation achieves both ease of insertion and uniform tension distribution simultaneously.
Solution Approach 2:
The invention adds the dimension of multiple anchoring points along the length of the device, transforming from single-point to multi-point anchoring. This dimensional change enables uniform tension distribution without compromising insertion ease, as all points are accessed through one entry site.
