Mesh Assembly with Diagonal Hook Members for Soft Tissue Fixation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mesh assemblies for soft tissue lifting face issues with adhesion strength under shaking or external shock, leading to potential separation from the skin tissue, and difficulty in maintaining the correct position during procedures due to instability.
Innovation Solution
A mesh assembly with a fixed member and a hook member composed of protrusions on the fixed member's surface, designed to enhance adhesion power and secure fixation, using threads that are harmless to humans, and forming grooves to prevent thread snapping, with a method involving adhesion and groove formation to create the hook member.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the mesh assembly is inserted into the skin to increase adhesion area, then adhesion power is improved, but the mesh assembly separates from the skin tissue due to shaking or external shock
Solution Approach 1:
The mesh assembly utilizes a porous net body structure with multiple through holes that allows skin tissue to grow through and adhere to the mesh. This porous configuration increases the effective adhesion area while maintaining structural integrity against shaking and external shock, resolving the contradiction between adhesion power and fixation stability.
Solution Approach 2:
The mesh assembly combines the net body made of flexible material with rigid fixation members that have biting portions. This composite structure integrates the advantages of both flexible materials (for adhesion) and rigid structures (for stable fixation), preventing separation due to external forces while maintaining strong adhesion to the skin tissue.
2Strength
If the mesh assembly is inserted into the skin to increase contact area, then adhesion power is improved, but the mesh assembly deviates from the targeted position due to shaking or external shock
Solution Approach 1:
The fixation members with biting portions are pre-positioned at specific locations on the mesh assembly before insertion. These fixation members engage with the skin tissue in advance, anchoring the mesh assembly at the targeted position and preventing deviation caused by shaking or external shock during and after the procedure.
Solution Approach 2:
The porous net body structure allows skin tissue to penetrate and interlock with the mesh, creating a stable positional relationship. This tissue-mesh interlocking through the porous structure prevents the mesh from deviating from the targeted position while maintaining adhesion.
3Strength
If the mesh assembly is inserted into the skin to increase contact area, then adhesion power is improved, but the mesh assembly is not fixed to the correct position due to shaking or external shock
Solution Approach 1:
The fixation members are pre-configured on the mesh assembly with specific geometries designed to engage with skin tissue at precise locations. This preliminary configuration ensures that when the mesh is inserted, the fixation members automatically engage at the correct position, maintaining positioning accuracy despite shaking or external shock.
Solution Approach 2:
The combination of the flexible net body with rigid fixation members creates a composite structure where the rigid fixation members provide precise positional anchoring while the flexible net body maintains adhesion. This composite design ensures both correct positioning and strong adhesion simultaneously.

AI summary
Provided is a mesh assembly inserted to a soft tissue or a human tissue for lifting the soft tissue, the mesh assembly including: a mesh member inserted into the soft tissue or human tissue and supporting the tissue; a fixed member provided at the mesh member and adopted to increase a coupling force in the soft tissue or the body; and a hook member formed on an upper surface or a lower surface or both of the fixed member to protrude in a diagonal direction, so that fixation of the soft tissue or human tissue can be firmly conducted, thereby allowing the soft tissue and the like to be fixed at a normal position without undergoing an influence by shaking or an external shock.
