Patent ID: 11642109

Abstract:
A soluble needle (100) for hair transplantation, wherein the soluble needle (100) comprises a fixing plate (30) and a plurality of micro-needles (20) made of water-soluble polymers arranged on the fixing plate (30), wherein each of said micro-needle (20) comprises a needle wall (21) to penetrate scalps and a needle cavity (22) confined by the needle wall (21) and configured for accommodating a hair follicle. A method of manufacturing a soluble needle (100) for hair transplantation, wherein the method includes: dissolving water-soluble polymers in water to prepare a molding solution (S101); delivering the molding solution into a mold (S102); letting the molding solution settle in the mold to shape (S103); and separating and removing the mold to produce the soluble needle (S104). The soluble needle (100) effectively shortens the time of surgery, reduces the pain of the patients, and increases the viability rate of transplanted hair follicles.
