According to the survey, about 200,000 people in China have rhinoplasty every year, and about 50% of them use filler injection. But last year alone, there were three cases of blindness caused by improper injection rather than filler problems. At present, medical research believes that the safety of injection has nothing to do with the doctor's department, but is closely related to the anatomical variation of blood vessel direction and the tools used for injection (sharp needle or blunt needle). In response to these cases, the well-known cosmetic medical association in China replied to Fu Weibu, asking doctors to use "blunt needles" as much as possible when injecting fillers around the eyes to avoid the risk of blindness caused by occlusion of ophthalmic arteries. The safety of blunt needle is high. Consumers need to use blunt needles at their own expense. As the name implies, the front end is blunt. Generally speaking, the tip is designed as a round head. Therefore, if you come into contact with important nerves and blood vessels in the process of beating, you will slide down without hurting them. At present, except for a few manufacturers of hyaluronic acid, the application of blunt needles in the micro-plastic surgery market is not very popular, and most doctors still use sharp needles to smear hyaluronic acid. The reason is not only the use habits of domestic doctors, but also the consideration of cost. The cost of blunt needle is almost more than 100 of that of sharp needle, which greatly reduces the doctor's willingness to use it. Therefore, it is suggested that consumers can ask doctors to apply fillers with blunt needles at their own expense to reduce possible risks and medical disputes. Medical devices with the number of blunt needles as Grade II risk must be inspected and licensed. Blunt needle belongs to the second-class risk medical device under the specification of the Ministry of Health, which has certain use risk. The reason is that the subcutaneous tissue uses a blunt needle, and if the disinfection and sterilization procedures are not rigorous enough, it is easy to cause unnecessary infections and complications. Therefore, it is necessary to use the medical device license that has been inspected and registered by the Ministry of Health, and clearly indicate the "Medical Device License Number" on the product packaging (such as the Ministry of Health). In addition, before using the blunt needle, it is necessary to carefully check whether the seal is complete, so as to avoid being polluted by the surrounding environment and losing the isolation effect.
