Abstract

An injection needle for filling that can avoid vascular embolism. The front end of the needle body is equipped with a needle point made of degradable material. The needle point and the front part of the needle body are sprayed with a coating made by electrospinning technology; the coating is made of collagen , chitosan, hyaluronic acid, gelatin, collagen and chitosan blends and other biodegradable materials. After the injection filling needle of the present invention penetrates into the skin and reaches the site to be filled, the needle tip with inverted teeth hooks and locks the soft tissue around the filling site, and the injection filling needle retracts and injects filling materials (hyaluronic acid, fat, etc.) at this time. The material is fixed in the electrospinning membrane that is detached from the needle body. The needle tip and the electrospinning membrane sleeve of the injection filling needle of this invention are made of degradable materials, which can prevent the injection material from entering the blood vessel and causing blood vessel damage during injection filling. Embolism can be degraded into metabolizable products in the human body at the same time, without any residue, and has high biological safety, thus ensuring a good injection filling effect.

Description

technical field [0001] The invention relates to an injection needle for filling which can avoid blood vessel embolism, and belongs to the technical field of medical instruments. Background technique [0002] Due to the advantages of short treatment time, fast recovery, and good effect, facial cosmetic injection filling is favored by more and more beauty seekers and plastic surgeons. Hyaluronic acid (HA) and autologous fat are currently the most widely used injection materials. According to data released by the International Society of Aesthetic Plastic Surgery (ISAPS), 3,298,266 people received HA injections in 2017 alone, accounting for 14.1% of all cosmetic plastic surgery projects, and it is the second non-surgical cosmetic plastic surgery after Botox injections. projects, accounting for 25.4% of non-surgical cosmetic surgery projects. Autologous fat filling is derived from autologous adipose tissue, which can survive partly permanently in the body and has high tissue c...
