LASER IRRADIATION TIP, LASER IRRADIATION HANDPIECE, LASER TREATMENT APPARATUS, AND LASER IRRADIATION TIP END MEMBER

摘要

A laser irradiation tip has a main body and a tip end portion. The main body is connected with a handpiece and irradiating therapeutic laser with high absorbability in water. The tip end portion being connected with the main body. The main body of the laser irradiation tip has an optical fiber for guiding the therapeutic laser, a water flow path, and an air flow path in a parallel manner. The tip end portion of the laser irradiation tip has a connection portion with the main body, a water guide path communicated with the water flow path of the main body, an air guide path communicated with the air flow path of the main body, a fiber guide portion capable of inserting a tip side portion of the optical fiber, and a mixing chamber of water and air.
