摘要：
A laser therapeutic device for a laser endoscope capable of relatively reducing the diameter of the endoscope while being capable of emitting a laser beam of a uniform intensity over a wide area is provided. An optical guide element (a square-shaped rod lens 15, a guide tube 2b) having a quadrangular cross section and guiding a therapeutic laser beam emitted from the tip of an optical fiber toward the tip side of a probe is used. On the tip side of a probe tube 2 being a barrel, using clearances C1 to C4 formed between the optical guide element and the inner circumferential surface of the probe tube, a camera unit 11 as imaging means and white-color LED units 12 and an ultraviolet LED unit 13 as illumination means are arranged.
