Laser device for an endoscope

Claim 1

A combination of an endoscope and laser device, wherein the endoscope comprises an insertable channel, a laser probe which is detachably taken into the insertable channel and is provided with a light-emitting member projecting from the insertable channel, and an observation section; and the laser device emits medical treatment laser beams and illumination light beams into the endoscope through the laser probe, and comprises a housing provided with a light-emitting section to which the laser probe can be connected, a medical treatment laser beam oscillator held in the housing conprising an infrared laser beam oscillator which can emit laser beams, a light source means received in the housing which can selectively emit at least two visible rays having different colors, said light source means being capable of issuing nonmonochromatic light beam and having means for selectively converting said nonmonochromatic light beams into light beams having at least two different colors comprising two different colored filters and means for selectively setting said two filters on the optical axis of the nonmonochromatic light beams, and an optical system which converges laser beams emitted from the medical treatment laser beam oscillator and visible rays sent forth from the assembly of illumination light sources, thereby conducting said laser beams and illumination light beams to the light-emitting section.
