Description

A blunt needle for rejuvenation plastic surgery

technical field

The utility model relates to the technical field of plastic surgery instruments, in particular to a blunt needle for rejuvenation plastic surgery.

Background technique

In recent years, injection of hyaluronic acid is often used in rejuvenation plastic surgery to achieve the effect of wrinkle removal. This cosmetic injection method has been favored by many beauty seekers for its convenience, speed and tracelessness. It is popular as a "lunch beauty". Using a sharp needle to inject hyaluronic acid, if the doctor's technique is not in place, bruising or even more serious complications will occur. The emergence of blunt needle injection technology, its excellent safety can just avoid similar accidents. Painless blunt needle injection, this drug delivery system can avoid needle tip damage to the human body, prevent drug leakage and bleeding at the injection site, and can inject highly viscous or particulate-containing drugs at any depth of the skin (intradermal or intramuscular). The mixture is precisely administered, allowing the drug to penetrate into difficult-to-inject areas where ointments cannot be used.

At present, when using a blunt needle for injection, an ordinary sharp needle (hollow needle tube, oblique needle tip) is used to make a hole in the skin, and then the blunt needle can be used to enter the skin for injection; most of the existing blunt needles use The round needle tip has great resistance during use, is not easy to operate, and is easy to deviate from the puncture direction; the needle tip of a sharp needle used with a blunt needle is actually like a flat bayonet, "cutting" the skin into a straight opening; and When the round-headed blunt needle that follows is inserted through the mouth, the skin tissue of the in-line opening will be squeezed or torn apart by the round-headed blunt needle, causing pain or secondary trauma.

Therefore, the injection process of the current rejuvenation plastic surgery has the disadvantages of difficult injection operation, imprecise injection position, and easy to cause secondary trauma.
