Elastic Lifting Thread with Thorn and Binding Projections
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional lifting threads used in surgical operations for skin lifting have projections that are not elastic, leading to damage of subcutaneous tissue, unintended tissue sinking, and a short-lasting lifting effect due to rapid melting of projections and inelasticity.
Innovation Solution
The improved lifting thread features a dual-part design with thorn projections for lifting and binding projections for fixation, both of which are elastic, increasing the cross-sectional area and maintaining shape, allowing for adjustable lengths to enhance lifting duration and prevent tissue sinking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If thorn-like projections are formed entirely around the lifting thread, then lifting capability is improved, but subcutaneous tissue damage occurs and the lifting effect decreases over time
Solution Approach 1:
The lifting thread features different projection types in different regions: thorn projections with elastic properties in the lifting part for gentle tissue engagement, and binding projections in the fixed part for secure anchoring. This local differentiation allows the thread to provide strong lifting capability while minimizing tissue damage through selective application of different projection characteristics in different functional zones.
Solution Approach 2:
The projections are designed with elastic properties that allow them to deform and adapt to tissue characteristics. The elastic thorn projections can flex during insertion and adjustment, reducing mechanical damage to subcutaneous tissue while maintaining lifting effectiveness. The binding projections also exhibit elasticity to accommodate tissue movement without causing damage.
2Duration of action of moving object
If projections are formed on the lifting thread, then skin lifting is achieved, but the projections melt rapidly and lose elasticity causing tissue sinking
Solution Approach 1:
The lifting thread is constructed from composite materials that combine high melting point components with elastic elements. The thread core provides structural integrity and resistance to melting, while the elastic thorn and binding projections maintain their shape and mechanical properties over time. This composite structure prevents the rapid melting and loss of elasticity that plagues conventional lifting threads.
3Ease of operation
If the lifting thread diameter is small, then insertion ease is improved, but tensile strength is insufficient causing tissue damage
Solution Approach 1:
The lifting thread employs a dynamic structure where the elastic projections can expand and contract during insertion and operation. The thread maintains a compact profile for easy cannula insertion, then the elastic thorn and binding projections expand to engage tissue securely. This dynamic behavior allows small diameter insertion while achieving sufficient tensile strength through projection engagement.
4Area of stationary object
If projections are entirely formed on the lifting thread, then lifting coverage is improved, but unintended tissue sinking occurs
Solution Approach 1:
The lifting thread is segmented into distinct functional parts: a lifting part with elastic thorn projections for gentle tissue engagement and lifting, and a fixed part with binding projections for secure anchoring. This segmentation prevents unintended tissue sinking by concentrating binding functions in the fixed part while the lifting part provides distributed, gentle elevation across the treatment area.
