Provided is a medical treatment apparatus using laser beams, which is used for treating arthritis, myositis, chronic pains and so on. A medical treatment apparatus using laser beams includes: a body a main laser unit irradiating a main laser beam in a direction perpendicular to an area to be treated a plurality of auxiliary laser units irradiating auxiliary laser beams to form a focus on a central axis of the main laser beam and an angle adjustment unit adjusting a focal distance by rotating the auxiliary laser units. The medical treatment apparatus using laser beams is capable of easily varying the angle and distance of the focus of irradiated laser beams. In addition, a treatment effect can be enhanced by the laser beams having different intensities, and the absorption rates of the laser beams can be controlled based on the color of light which is separately irradiated onto the skin of an affected area.
