High frequency treatment handpiece having roller electrodes

A high frequency treatment handpiece having roller electrodes, the high frequency treatment handpiece comprising:

• a handpiece casing part;
• and
• a plurality of roller electrode members rotatably positioned on a lower surface of the handpiece casing part and configured to apply a high frequency by being brought into contact with a skin of a patient,
• wherein the plurality of roller electrode members are selectively used in a roller fixed mode that limits a rotation and a one direction movement mode, and the plurality of roller electrodes members are rotated only in one direction by a ratchet part,
• wherein the ratchet part includes:
• a ratchet wheel member positioned in a hollow hole of the plurality of roller electrode members and on which the plurality of roller electrode members are rotatably positioned, and
• a pawl member positioned on the plurality of roller electrode members and caught on outer teeth of the ratchet wheel member in a state of being elastically supported by a spring so as to allow the plurality of roller electrode members to rotate in one direction.
