AI summary

Disclosed is an invasive high-frequency treatment device. The invasive high-frequency treatment device includes multiple micro needles including a first micro needle and a second micro needle, an elevation unit configured to raise the micro needle, and a control circuit configured to control the elevation unit. The control circuit determines a procedure zero point of the elevation unit corresponding to the multiple micro needles in an initialization step of the invasive high-frequency treatment device, and controls the elevation unit to rise at a predetermined height from the procedure zero point in a procedure step of the invasive high-frequency treatment device. Accordingly, it is possible to make consistent the location of the micro needles prior to a procedure regardless of conditions for a design, an assembly, and use.
