1. A treatment apparatus, comprising:
a handpiece;
a tip module provided at an end of the handpiece, the tip module including an inner part in which micro needles and a substrate are disposed and a wall sealing the inner part, the micro needles being fixed to the substrate, the wall having at least one hole;
a driving unit disposed on an end portion of the handpiece, the driving unit including an output terminal that moves along the at least one hole and pressurizes the substrate when the driving unit operates; and
a cooling unit having a fan that supplies cooling air towards the inner part of the tip module through the at least one hole, thereby cooling all micro needles together,
wherein each of the micro needles comprises a first part and a second part, the second part being a protruded part penetrating the substrate to extend towards the handpiece in a specific length, the first part and the second part being included in a single body of each of the micro needles,
wherein the first part of each of the micro needles is configured to be inserted into a target tissue, so that energy is applied to the micro needles, the second part being positioned opposite to the first part of each of the micro needles with respect to the substrate,
wherein the cooling unit is configured to directly cool the second parts of the micro needles respectively without directly cooling a surface of the target tissue, after ending the applying of the energy,
wherein the specific length is shorter than a length of the first part of each of the micro needles, and
wherein the cooling unit is disposed between the driving unit and the wall of the tip module.
