Abstract
A combined operating microscope and illumination system having a coaxial and/or par focal light source for illumination for precise instrumentation during intraocular and other operating procedures. Stereoscopic view for a surgeon and an assistant is provided with an alternatively selective light diverting system in the assistant's light system for photographic purposes. Coaxial and par focal slit illumination are achieved by a light source movable on an arc shaped tract without reflecting light through the surgeon's lens system thereby permitting additional space for a second light system to the assistant without reducing that available to the surgeon.
Claims2
A dual stereo-microscope for performing micro-surgery comprising:
- an objective lens positioned to view an operating area and on a first line effective to develop a collimated beam of light from said operating area;
- a first pair of stereo-lenses disposed in and normal to said collimated beam and adapted to intercept and develop a first pair of tracts of light;
- a first pair of stereo-eyepiece lenses mounted for observation by a surgeon of the light intercepted by said first pair of stereo-lenses;
- meaans defining a first light transmission path for transmitting the total light intercepted by said first stereo-lenses to said first stereo-eyepiece lenses;
- a second pair of stereo-lenses disposed in and on a second line normal to said collimated beam and perpendicular to said first line and adapted to intercept and develop a second pair of tracts of light;
- a second pair of stereo-eyepiece lenses mounted for observation by a second observer of the light intercepted by said second pair of stereo-lenses;
- and
- means defining a second light transmission path for transmitting the total light intercepted by said second stereo-lenses of said second stereo-eyepiece lenses.
