Abstract
835,172. Endoscopes. CENTRE NATIONAL DE LA RECHERCHE SCIENTIFIQUE. Jan. 22, 1958 [Jan. 24, 1957], No. 2232/58. Class 81 (2). [Also in Group XX] An endoscope comprises a light source, the light from which is concentrated on one end of a light-guide rod, and an endoscope tube disposed parallel to the rod and displaceable relatively thereto. As shown, the endoscope comprises an air-cooled casing containing a lamp 2 the light from which is condensed at 8 and reflected at 9 into a transparent rod 20 as of quartz which fits into an aperture in the upper end of the casing and is supported at 22 on a block 16 which plugs into the casing. A second block 17 is also plugged into the casing and supports a clamp 26 through which passes an endoscope tube 24; the clamp 26 and a double ring 28 hold tube 24 parallel to rod 21. Preferably tube 24 is moved so that one end thereof is level with the bevelled end 21 of rod 20. Direct viewing of a cavity in which tube 24 and rod 20 may be accommodated is effected through the enlarged end 25 of tube 24 or a camera may be attached to this end. Specifications 720,141 and 792,099 are referred to.
