Tissue Lifting Implant With Pore-Filled Mesh
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional tissue lifting methods using medical threads face issues such as uneven tissue pulling, cog damage, thread escape, low adhesion, and recurrence of sagging due to inadequate fixing strength, especially in areas like the naso-labial fold, and require invasive procedures with potential tissue damage and complex removal processes.
Innovation Solution
An implant integrating a bioimplantable thread with a mesh member having numerous pores, which is coupled to the thread to enhance adhesion and tensile strength, allowing for natural tissue pulling and reducing damage, while being designed for easy removal and biocompatibility to prevent foreign body sensations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a conventional medical thread with cogs is used for tissue lifting, then the thread can pull and lift sagged tissue, but the cogs are damaged and the thread escapes from the tissue due to low adhesion and insufficient fixing strength
Solution Approach 1:
The patent combines a medical thread with a mesh structure into an integrated implant. The mesh structure provides a larger surface area for tissue adhesion while the thread provides tensile strength for lifting. This merging of functions resolves the contradiction by distributing the lifting force across the mesh-tissue interface rather than relying solely on cog-tissue interaction, preventing both thread escape and cog damage.
Solution Approach 2:
The mesh structure is inherently porous, allowing tissue to grow through and adhere to the mesh structure. This porosity increases the effective contact area between the implant and tissue, significantly enhancing adhesion strength and preventing thread escape while reducing stress concentration that would damage cogs.
2Ease of operation
If a conventional thread is used for tissue lifting, then the thread can be inserted and pulled to lift tissue, but it causes uneven pulling and damages tissue due to point contact instead of distributed force
Solution Approach 1:
The invention transitions from a one-dimensional thread to a two-dimensional mesh structure. This dimensional change allows the implant to distribute lifting forces across a broader area of tissue, transforming point contact into distributed contact. The mesh structure can engage multiple tissue layers simultaneously, providing even pulling without concentrating stress at single points, thereby preventing tissue damage.
3Strength
If a band shaped mesh is used for tissue lifting, then the mesh can provide surface support, but it requires invasive incision and complex removal procedure
Solution Approach 1:
The implant is segmented into a flexible mesh structure that can be inserted through a small incision rather than requiring a large incision. The mesh can be folded or rolled for insertion and then expanded to provide surface support. For removal, the segmented structure allows it to be collapsed back into a compact form and extracted through the same small incision, significantly simplifying the removal procedure compared to a rigid band-shaped mesh.
