Laser treatment device

摘要: A laser treatment device provided with a light source, laser-light transmitting optical fiber for output from the source and probe guiding transmitted by to an object be irradiated. Further, is constituted separated fiber. Moreover, cooling chamber fibers in neighborhood of end fiber, which output, input Thereby, medical deep part affected or diseased region can achieved without worsening state exit optical-fiber. optical-fiber kept favorable condition even after region. Thus there no obstacle next thereof.
