In fact, blunt needles have been successfully used in autologous fat transplantation. In recent years, they have been applied to injection filling for cosmetic reasons for safety reasons.
The needle of the sharp needle is like a bayonet, the tissue it passes through will first be "cut" by it, easy to cut the blood vessel and cause bleeding, and if the filler is injected into the blood vessel, it will cause skin necrosis at best, and serious problems such as blindness, cerebral infarction and myocardial infarction can be caused at worst. At the same time, when injecting a large area with a sharp needle, it is necessary to inject multiple points, which is easy to increase the discomfort and discontinuity of the transition site.
The entire needle of the blunt needle is made of flexible and elastic stainless steel, and the rounded blunt tip can advance smoothly in the soft tissue, which can reduce postoperative swelling. The flexible needle tube can better meet the needs of face curve, so it can make a more even and natural face line with the fewest needle holes.
