Mesotherapy, in which a small amount of therapeutic drugs is injected into the skin layer and subcutaneous layer, is acute and chronic pain, partial obesity, and cosmetic plastic surgery.It increases blood circulation and lymph circulation at the treatment site to increase various pain, partial obesity, and skin. It removes wrinkles, prevents skin aging, increases skin elasticity, has immediate effects, has no pain during treatment, and has almost no side effects, and has been widely used in recent years.

In such a mesotherapy procedure, control according to the thickness, depth, angle, injection amount, and treatment site of the needle must be elaborately performed at the fingertips. In general, when a practitioner receives a prescribed drug in a disposable syringe and manually injects it into the treatment site, a lot of time is spent due to a long procedure, and there is a problem that the procedure is very inconvenient due to excessive fatigue. A mesogun or an injection gun is used as a means for injecting drugs.

However, since it is very cumbersome and inconvenient to inject one by one into a wide treatment area such as the skin scalp with a single needle, a multi-needle needle composed of a plurality of needle tubes has been developed. However, in the case of skin treatment with a multi-needle within 1~1.5mm, a needle including a suction cap that sucks the skin area into which the needle is to be inserted has been developed because the multi-needle needle tubes push the skin and are not properly inserted into the skin.
