Abstract: The present invention provides a surgical thread, comprising a modified cross-section fiber, wherein the modified cross-section fiber is in a twisted state. The surgical thread of the present invention has advantages of good coefficient of kinetic friction, good tensile strength, good elongation rate and good softness, and good safety, comprising no inflammatory potential, no cytotoxicity, no pyrogen, no acute systemic toxicity and no intradermal irritation potential, and has the efficacy of promotion of collagen formation, thereby being suitable for embedding in the face. The present invention further provides a cosmetic treatment and a manufacturing method for the surgical thread.

Abstract: A syringe includes a sleeve and a pressure vessel with high pressure fluid therein. The sleeve further comprises a sleeve piston. As the high pressure vessel contacts the sleeve piston, and a bump on the sleeve piston destroys the airtight status of the high pressure vessel. While the seal of the high pressure vessel is removed, the compressed fluid flows into the sleeve through the opening of the high pressure vessel and the hole of the sleeve piston. When the closed end of the sleeve moves closer to the closed end of the sleeve piston, the fluid in the sleeve is pressed and flows out of the sleeve through the sleeve hole of the sleeve.
