Description

Technical Field

[0001] This utility model relates to the field of medical polymer materials technology, specifically to an expanded polytetrafluoroethylene (ePTFE) with tear trough depressions. Background Technology

[0002] Currently, the most commonly used materials for filling tear troughs in the domestic market are hyaluronic acid, hyaluronic acid compound emulsion, and collagen. These materials have relatively short-lasting effects, and the skin under the eyes is thin with delicate blood vessels, posing certain risks during injection. Expanded polytetrafluoroethylene (ePTFE) material can solve these problems when used to fill tear trough depressions. Importantly, it has good biocompatibility, is soft, and can be implanted long-term.

[0003] Therefore, it is necessary to develop a type of expanded polytetrafluoroethylene (ePTFE) that can accommodate tear trough depressions. Utility Model Content

[0004] The purpose of this invention is to provide a expanded polytetrafluoroethylene (ePTFE) with tear trough depressions to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a expanded polytetrafluoroethylene (ePTFE) with tear trough depressions, comprising a tear trough filling ePTFE, wherein a three-dimensional mesh is provided at the center of the tear trough filling ePTFE;

[0006] The tear trough filling emulsion includes, from the outside to the inside, an outer protective layer, a buffer layer, a functional layer, a reinforcing layer, and a bottom support layer.

[0007] Preferably, the left side of the tear trough filling protrusion is a thick area, the right side of the tear trough filling protrusion is a thin area, and the whole protrusion has a gradually thickening concave surface design.

[0008] Preferably, the three-dimensional mesh is porous and can adapt to changes in tear troughs.

[0009] Preferably, the thickness of the outer protective layer, buffer layer, functional layer, reinforcing layer and bottom support layer is set to 1mm-4mm.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] By employing designs with varying thicknesses based on the anatomical characteristics of tear troughs, the tear trough filler propellant gradually thickens from the edge to the center. This effectively disperses pressure, reduces skin irritation, provides a natural appearance, and better integrates with surrounding tissues. The three-dimensional mesh structure in the center of the tear trough filler provides excellent breathability and flexibility, effectively addressing the issue of short-lasting effects associated with materials like hyaluronic acid, hyaluronic acid composite emulsions, and collagen. It also minimizes the safety risks associated with injection-based fillings, effectively improving the safety of tear trough filler.

[0012] By employing a multi-layered approach in tear trough filling emulsion, each layer possesses unique functions and effects, working together to enhance the overall performance of the tear trough filling emulsion and ensuring its advantages in safety, comfort, and aesthetics.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] This utility model provides the following technical solution: a expanded polytetrafluoroethylene (ePTFE) with tear trough depressions, please refer to [link / reference]. Figures 1-2 The product includes a tear trough filling implant 1. The left side of the tear trough filling implant 1 is designed as a thicker area, and the right side is designed as a thinner area. The overall design is a gradually thickening concave surface. By adopting different thicknesses according to the anatomical characteristics of the tear trough, the tear trough filling implant 1, which gradually thickens from the edge to the center, can effectively disperse pressure, reduce skin irritation, provide a natural appearance, and better integrate with the surrounding tissue. The center of the tear trough filling implant 1 has a three-dimensional mesh 2. The three-dimensional mesh 2 is porous and can adapt to changes in the tear trough. The three-dimensional mesh 2 in the middle of the tear trough filling implant 1 adopts a mesh structure, which makes the tear trough filling implant 1 have good breathability and flexibility. This effectively solves the problem of short maintenance when using materials such as hyaluronic acid, hyaluronic acid composite emulsion, and collagen. It also avoids the safety risks that may occur when filling by injection. This effectively improves the safety of the implant for tear trough depression.

[0018] The tear trough filling emulsion 1 comprises, from the outside to the inside, an outer protective layer 101, a buffer layer 102, a functional layer 103, a reinforcing layer 104, and a bottom support layer 105. The thickness of the outer protective layer 101, buffer layer 102, functional layer 103, reinforcing layer 104, and bottom support layer 105 is set between 1mm and 4mm, with a range of 3mm. Based on the multi-layered effect of the tear trough filling emulsion, the first layer, the outer protective layer 101, uses a soft, biocompatible polymer, such as polyvinyl alcohol, to provide a smooth surface and reduce friction with the surrounding skin; it also protects the inner layer of the emulsion from external contamination, improving safety and comfort. The second layer, the buffer layer 102, uses a mixture of polylactic acid (PLA) and a plasticizer, possessing moderate elasticity and flexibility, effectively buffering the impact of external forces. The first layer, the pressure-relieving layer 103, is a functional layer made of bioactive materials, such as polymers containing hyaluronic acid, which provides better filling effect, maintains good moisture content, improves skin radiance, and directly improves the appearance of tear troughs. The second layer, the third layer, is made of high-strength biopolymers, such as polycaprolactone (PCL) or polyester, which enhances the strength and durability of the expanded polytetrafluoroethylene (ePTFE), extends its service life, and ensures stability in the body. The third layer, the bottom support layer 105, is made of biodegradable polymers, such as polylactic acid (PLA) or polycarbonate, which provides support for the overall structure, ensures the stability of the ePTFE shape, and allows it to adapt to the dynamic changes of tear troughs. Each layer has its unique function and effect, and they can work together to improve the overall performance of the tear trough filling ePTFE 1.

[0019] Working Principle: When using this invention, by adopting a design with varying thicknesses based on the anatomical characteristics of tear troughs, the tear trough filling emulsion 1, which gradually thickens from the edge to the center, can effectively disperse pressure, reduce skin irritation, provide a natural appearance, and better integrate with surrounding tissues. The three-dimensional mesh 2 in the middle of the tear trough filling emulsion 1, with its mesh structure, provides excellent breathability and flexibility, effectively solving the problem of short-lasting effects when using materials such as hyaluronic acid, hyaluronic acid composite emulsions, and collagen. It also minimizes the safety risks associated with injection filling, effectively improving the safety of the emulsion for tear trough depressions. Based on the multi-layered effect of the tear trough filling emulsion, the first layer, the outer protective layer 101, uses a soft, biocompatible polymer, such as polyvinyl alcohol, to provide a smooth surface and reduce friction with surrounding skin; it also protects the inner layer of the emulsion from external contamination, enhancing safety and comfort. The second layer serves as a buffer. Layer 102 is made of a mixture of polylactic acid (PLA) and plasticizer, possessing moderate elasticity and flexibility. It effectively cushions the impact of external forces, disperses pressure, enhances comfort during wear, and reduces discomfort. The third layer, functional layer 103, uses bioactive materials, such as polymers containing hyaluronic acid, to provide better filling effect, maintain good moisture content, improve skin radiance, and directly improve the appearance of tear troughs. The fourth layer uses high-strength biopolymers, such as polycaprolactone (PCL) or polyester, to enhance the strength and durability of the expanded polytetrafluoroethylene (ePTFE), extend its service life, and ensure stability within the body. The fifth layer, bottom support layer 105, uses biodegradable polymers, such as PLA or polycarbonate, to provide overall structural support, ensure the stability of the ePTFE shape, and allow it to adapt to the dynamic changes in tear troughs. Each layer has its unique function and effect, working together to enhance the overall performance of the tear trough filling ePTFE 1, ensuring its advantages in safety, comfort, and aesthetics.
