Dynamic Tensioning System for Wound Stabilization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for pre-surgical tissue expansion and post-surgical tissue stabilization are cumbersome, invasive, and often lead to complications such as wound reopening and prolonged healing times, while existing wound closure techniques fail to provide stable immobilization and optimal healing conditions.
Innovation Solution
A dynamic tensioning system comprising anchoring elements, a dynamic membrane, and a limiting element that applies controlled tension to tissues, stabilizes wounds, and promotes tissue expansion and healing, using breathable materials and adjustable tension to prevent dehiscence and facilitate wound closure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If adhesive tissue glues are used to bond wound edges, then wound closure is achieved, but wound edge approximation deteriorates due to glue leaking into the wound
Solution Approach 1:
The patent removes the adhesive component from the wound closure system entirely. Instead of using adhesive glues that bond wound edges, the invention employs a non-adhesive closure device that mechanically approximates wound edges through a closure element that can be adjusted and secured without adhesive, thereby preventing glue leakage into the wound while maintaining effective wound closure.
2Stability of the object's composition
If adhesive tapes are placed across the incision, then wound stabilization is provided, but wound eversion is prevented due to direct adherence to the wound surface
Solution Approach 1:
The patent eliminates adhesive tapes that directly adhere to the wound surface. The closure device uses a non-adhesive mechanism where the closure element is secured to the tissue edges mechanically rather than through adhesive bonding, allowing the wound to evert naturally while still providing stabilization and protection during the healing process.
3Volume of moving object
If balloon-type tissue expanders are embedded under the skin, then tissue expansion is achieved, but the procedure becomes invasive and complicated requiring multiple operations
Solution Approach 1:
The patent employs a disposable, single-use closure device that is applied externally to the wound rather than requiring embedded implantable devices like balloon expanders. The device is applied in a single procedure, provides the necessary tissue expansion and stabilization, and is then removed after serving its purpose, eliminating the need for multiple operations and reducing procedural complexity.
4Volume of moving object
If a constant load is applied to body tissue, then mechanical creep and tissue expansion are promoted, but the process takes lengthy time and requires multiple physician visits
Solution Approach 1:
The patent employs a dynamic closure device with an adjustable closure element that can be modified during the healing process. The device allows for dynamic adjustment of the tension and expansion force applied to the tissue, enabling optimization of the healing conditions without requiring multiple physician visits for incremental adjustments, thereby reducing overall treatment time while maintaining effective tissue expansion.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system effectively stabilizes wounds, reduces pain and discomfort, promotes tissue expansion, and enhances healing by applying controlled tension, reducing the risk of wound reopening and facilitating faster recovery, particularly for chronic wounds and post-surgical tissue management.
Implementation Method 1
