Implant for face filling and preparation method thereof

Abstract

The invention discloses an implant for face filling and a preparation method thereof. The implant for the face filling is a mixed suspended matter prepared by expanded polytetrafluoroethylene particles and a mixture, wherein the expanded polytetrafluoroethylene particles are obtained through the steps of: based on polytetrafluoroethylene as a raw material, expanding via extrusion and stretch, sintering, forming and cutting; the mixture contains sodium hyaluronate gel or botulinum toxin type A; and the mixed suspended matter can also contain antibiotics. The invention also provides the preparation method of the implant for the face filling. The implant for the face filling, prepared by adopting the method, can be implanted by adopting an injection way, is small in wound and convenient for forming, has good biocompatibility and has the advantages that through controlling sizes of micro pores in the expanded polytetrafluoroethylene particles, the histiocyte can grow in and the implant for the face filling can be permanently planted and cannot be absorbed by the body.

Description

Technical field [0001] The invention relates to a medical filler, which belongs to the field of medical devices; in particular, to a face-filled implant and a preparation method thereof. Background technique [0002] Both congenital and posterior human facial depressions seriously affect the overall characteristics of the person. With the improvement of people's living standards, more and more people choose to use surgery to reshape facial features, especially rhinoplasty. There are two types of facial soft tissue filling surgery: the traditional way of implanting a prosthesis and the more popular way of injection. [0003] Prosthesis implantation methods still occupy a certain market, because the effect of prosthesis implantation is relatively long-term. Because of the injection method, some effects can only last for 6 months, while prosthesis implantation, such as expanded polytetrafluoroethylene Can be permanently implanted. However, in this way, the surgical incision is larg...
