ENDOSCOPE APPARATUS
First Claim
1. An endoscope apparatus comprising:
- a first light source that outputs laser light for diagnosis for use in photodynamic diagnosis;
a second light source that outputs laser light for therapy for use in photodynamic therapy, wherein the laser light for therapy is different in spectrum from the laser for diagnosis;
an endoscope leading end portion to be inserted into an object to be examined;
an irradiation window provided in the endoscope leading end portion;
an observation window provided in the endoscope leading end portion;
a light irradiation unit that emits the laser light for diagnosis and the laser light for therapy to the object to be examined through the irradiation window; and
an emission angle changing unit that changes an emission angle at which the laser light for therapy is emitted through the irradiation window to be smaller than an emission angle at which the laser light for diagnosis is emitted, whereinthe object to be examined is observed through the observation window.

Abstract
An endoscope apparatus includes first and second light sources, an endoscope leading end portion, an irradiation window, an observation window, a light irradiation unit and an emission angle changing unit. The first light source outputs laser light for diagnosis. The second light source outputs laser light for therapy. The laser light for therapy is different in spectrum from the laser for diagnosis. The irradiation window and the observation window are provided in the endoscope leading end portion. The light irradiation unit emits the laser light for diagnosis and the laser light for therapy to the object through the irradiation window. The emission angle changing unit changes an emission angle at which the laser light for therapy is emitted through the irradiation window to be smaller than an emission angle at which the laser light for diagnosis is emitted. The object to be examined is observed through the observation window.
