Description

Technical Field

[0001] This utility model relates to the field of cosmetic hair transplantation technology, specifically to an artificial hair follicle and its usage method. Background Technology

[0002] Current hair transplantation methods are generally divided into artificial hair transplantation and autologous hair transplantation. Autologous hair transplantation involves extracting hair follicles from the patient's own body and transplanting them to the relevant area. The advantage of autologous hair transplantation is that once the hair follicles survive, they will grow healthy new hair and maintain the biological characteristics of the patient's own hair. Therefore, autologous hair transplantation is a very popular hair transplantation method.

[0003] However, autologous hair transplantation requires a sufficient number of hair follicles. If there are insufficient hair follicles, autologous hair transplantation is not possible. In this case, artificial hair transplantation is the only option. One drawback of existing artificial hair transplantation methods is that the artificial hair and follicles are fixedly connected. If an unexpected force is applied to the artificial hair, both the hair and follicle can be pulled out of the scalp, damaging the scalp and compromising the transplant's effectiveness. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide an artificial hair follicle. This invention can implant one or more hairs wrapped in a polymer material into the scalp to form hair that is visible on the outside. It does not require the collection of one's own hair follicles, and hair can be transplanted even if there are no hair follicles. The number of hairs is unlimited. The appearance of the fixed wig is consistent with real hair. It is not easy to fall out or turn white, and the hair transplant effect is good.

[0005] To achieve the above objectives, the present invention adopts the following solution: an artificial hair follicle, characterized in that it is composed of at least one hair and a biocompatible polymer material encapsulation body; The polymer material encapsulation is fixed in the middle section of the hair and does not cover the two ends of the hair; The hair is selected from real hair, synthetic hair, or a combination of both.

[0006] In this invention, the length of both ends of the hair can be adjusted as needed when wrapping and securing it. The middle fixing method provides bidirectional mechanical support to prevent the hair from coming out in both directions.

[0007] This invention uses a biocompatible polymer material to form an encapsulation with a rejection rate of <0.1%. Furthermore, the encapsulation surface can be provided with a microporous structure, which can accelerate cell adhesion.

[0008] In this invention, stem cell inducing factors (such as Wnt3a protein) can also be loaded onto the surface of the encapsulation to promote the directed differentiation of dermal fibroblasts into hair papilla cells, thereby achieving biofunctional integration.

[0009] This invention can use real hair to provide a natural texture. Synthetic hair can be used to customize color or curl.

[0010] As another improvement of the artificial hair follicle of this utility model, the polymer material encapsulation is in the form of a tubular, thin film, coating or olive-shaped structure, and has elastic deformation capability.

[0011] In this invention, the polymer material encapsulation is configured as a tubular structure, and its axial elastic modulus (0.5-3MPa) matches the mechanical properties of the dermis, buffering daily traction forces (such as 1-5N dynamic loads when combing hair), effectively preventing implant displacement and reducing the risk of folliculitis.

[0012] In this invention, the polymer material encapsulation is designed with an olive-shaped structure, mimicking the morphology of a hair follicle bulb, which reduces tissue shear stress during implantation. This minimizes capillary damage and accelerates wound healing.

[0013] As another improvement of the artificial hair follicle of this utility model, the polymer material encapsulation is integrated with the hair through injection molding, dip coating and curing, tube fixation or heat shrinking process.

[0014] As another improvement of the artificial hair follicle of this utility model, the surface of the polymer material encapsulation body is a smooth surface or a corrugated structure or is provided with anti-slip protrusions or barbs.

[0015] In one embodiment of this invention, the surface of the polymer material encapsulation is smooth. A smooth surface effectively reduces friction, making insertion and removal of the encapsulation smoother and reducing frictional damage to surrounding tissues. In artificial hair follicles, a smooth surface can reduce patient discomfort and provide a better user experience.

[0016] In one embodiment of this invention, the surface of the polymer material encapsulation is configured with a corrugated structure, significantly increasing the contact area with the scalp environment. The corrugated structure provides a hinge-like function, making the encapsulation easier to bend and deform in specific directions, adapting to the morphological changes of surrounding tissues and improving comfort and durability. In the direction perpendicular to the corrugations, the corrugated structure increases rigidity, preventing excessive bending or collapse of the encapsulation and providing better support. The corrugated structure can absorb and disperse impact energy, acting as a buffer and reducing the impact of external impacts on the encapsulation and surrounding tissues.

[0017] In one embodiment of this invention, the surface of the polymer material encapsulation is provided with anti-slip protrusions. These protrusions significantly increase surface friction, providing better grip and stability, ensuring the encapsulation's firmness within the perforated skin layer. This prevents the encapsulation from sliding or falling off due to external pulling during use.

[0018] In one embodiment of this invention, the surface of the polymer material encapsulation is provided with a barbed structure. This barbed structure allows for smooth insertion of the encapsulation but provides significant resistance during removal, achieving a secure unidirectional fixation. In this invention, the barbed structure can be bidirectional. One direction of the barb can be wrapped with a soluble film to close that section. After implantation through the skin penetration hole, the soluble film dissolves, opening the barb and allowing for fixation from both sides.

[0019] As another improvement to the artificial hair follicle of this utility model, the axial length of the polymer material encapsulation is 1-50mm and the diameter is 0.1-5mm.

[0020] As another improvement to the artificial hair follicle of this utility model, the axial length of the polymer material encapsulation is preferably 3-10 mm, and the diameter is preferably 0.3-1.5 mm.

[0021] As another improvement to the artificial hair follicle of this invention, the polymer material encapsulation is made of one of the following materials: medical-grade silicone rubber, polytetrafluoroethylene, medical-grade polyurethane, polycaprolactone, collagen, gelatin, silk fibroin, and chitosan.

[0061] Second, the artificial hair follicles of this utility model do not require the collection of one's own hair follicles, and hair can be transplanted even without hair follicles, with no limit on the number; the hair transplant process is simple and the cost is greatly reduced.

[0062] Third, the wigs fixed with artificial hair follicles using this utility model have the same appearance as real hair, are not easy to fall out or turn white, and can be replaced as needed. Attached Figure Description
