Optical fiber light guide 1 has flexibility and guides light including infrared rays emitted from a light source to probe 4 which is located at the tip end thereof, through a flexible guide tube 3. The tapered conduit part 5, 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 4. The rectilinear polarization plate 8 rectilinearly polarizes light including infrared rays emitted from the tip end plane of the tapered conduit part 5 and irradiates the same onto an affected part.
BACKGROUND OF THE INVENTION AND RELATED ART STATEMENT The present invention relates to an optical fiber unit for medical examination and treatment and arm device for the optical fiber. In particular, the invention relates to an optical fiber unit for medical examination and treatment which is able to cure or treat an affected part by a heating effect, etc. by irradiating infrared rays to the affected part, and an arm device for the optical fiber which is able to retain the optical fiber unit so as to easily operate the same.
OBJECTS AND SUMMARY OF THE INVENTION In view of the abovementioned points, it is therefore an object of the invention to provide an optical fiber unit for medical examination and treatment in which no light condensing lens group is required by making the tip end part of the optical fiber light guide a tapered conduit part, the diameter of which is gradually made smaller toward the tip end thereof.
BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a side elevational view showing an upper cross-section of an optical fiber unit for medical examination and treatment according to a first preferred embodiment of the invention.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a side elevational view showing an upper cross-section of the major parts of an optical fiber unit for medical examination and treatment according to the first preferred embodiment of the invention. The principal part of the optical fiber unit for medical examination and treatment according to the preferred embodiment consists of optical fiber light guide 1, protection pipe 2, flexible guide tube 3, probe 4, tapered conduit part 5 and tip end cap 6.
The first joint part 102′ of this example, which is constructed as described above, is such that the locking effected by the one-way clutch consisting of the notch 193 a of the hollow shaft 193 and the roller 200 can be manually cancelled by providing the same with a ball knob 203. That is, although the bearing member 195 can be rotated without any load when the same is rotated in the direction of arrow �a�, the roller 200 is engaged in the notch 193 a to effect the locking if the bearing member 195 is attempted to rotate in the direction of arrow �b�. When the ball knob 203 is pushed up from this locked state, the lock cancelling pin 201 is engaged with the roller 200 via the arm 202 and rotating plate member 199, thereby cancelling the engagement of the roller 200 with the notch 193 a of the hollow shaft 193, wherein the lock comes off. Therefore, since both the axial fixing member 191 and the bearing member 195 are made free, it is possible to comparatively easily shift down the first flexible arm part 103 to any desired inclination position. And if your hand is released from the ball knob 203 at a position where the first flexible arm part 103 is inclined, the rotating plate member 199 is reset by a restoration resiliency of the reset spring 104 to cause the roller 200 to be again engaged in the notch 193 a and to cause the one-way clutch to be locked again. Furthermore, in a case where the first flexible arm part 103 is reset to the initial erect position, since the lock of the one-way clutch does not operate, it is possible to reset the first flexible arm part 103 to the erect position with a comparatively weak force.
