An optical fiber unit for medical examination and treatment according to the invention has an object of not requiring a light condensing lens group by tapering the tip end side of the optical fiber light guide. Optical fiber light guide,has flexibility and guides light including infrared rays emitted from a light source to probe,which is located at the tip end thereof, through a flexible guide tube,The tapered conduit part,the diameter of which is made smaller toward the tip end thereof condenses the light and allows the same to be emitted from the tip end plane of the probe,The rectilinear polarization plate,rectilinearly polarizes light including infrared rays emitted from the tip end plane of the tapered conduit part,and irradiates the same onto an affected part.

Optical fiber unit for medical examination and treatment and arm device for the optical fiber

An arm device for retaining and positioning an optical fiber unit for medical examination and treatment, so as to easily operate the same. The arm device is provided with flexible arm parts and a lockable, rotatable joint assembly for easy manipulation and positioning of the optical fiber unit.
