The present invention relates to a low-power laser treatment device having an improved structure of a handpiece for treating a patient using a laser.

In general, a laser treatment device connects a handpiece to a main body having a power supply and a laser generator with a connecting cable, and the operator holds the handpiece and irradiates a laser to a specific area of the patient.

The laser treatment device controls the laser irradiated from the handpiece using a foot switch (or foot switch) installed in the body. In the following (Patent Document 1), a button unit that operates separately from the foot switch is installed in the handpiece, and as another example (Patent Document 2), an emergency switch is installed in the handpiece and the emergency switch is operated to provide power to the power supply unit of the body. supply can be controlled.
