Self-Retaining Hernia Mesh with Anchoring Structures
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional surgical implants for hernia management often lead to recurrent hernias due to displacement and cause inflammatory reactions and tissue trauma, especially when using staples or sutures for fixation.
Innovation Solution
A self-retaining surgical implant with a textile fabric featuring threads with anchoring structures that project from the fabric, allowing secure anchoring in biological tissues without additional fixing means, reducing the risk of inflammatory reactions and tissue trauma.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional fixing means (staples or sutures) are used to fix the mesh, then the mesh can be secured in position, but this leads to inflammatory reactions and additional tissue trauma
Solution Approach 1:
The mesh is equipped with self-retaining anchoring structures (protrusions, loops, or hooks) that enable it to secure itself to the tissue without requiring external fixing means such as staples or sutures. This self-service mechanism eliminates the need for additional fixing materials, thereby preventing the inflammatory reactions and tissue trauma associated with conventional fixing methods while maintaining reliable mesh positioning.
2Reliability
If additional fixing means are used to secure the mesh, then displacement is prevented, but the device complexity and number of incorporated materials increase
Solution Approach 1:
The anchoring function is merged directly into the mesh structure itself through integrated protrusions, loops, or hooks. This combines the mesh and fixing mechanisms into a single unified component, eliminating the need for separate fixing materials and reducing overall device complexity while maintaining effective mesh stabilization.
3Area of stationary object
If the mesh edges lie between tissue layers, then coverage is achieved, but fixing becomes difficult and inconvenient
Solution Approach 1:
The mesh's self-retaining anchoring structures enable it to secure itself automatically to the tissue layers it covers. This self-service capability allows the mesh to maintain its coverage area effectively while eliminating the difficulty and inconvenience of manual fixing operations, as the mesh fixes itself without requiring additional surgical steps or tools.
