Abstract
A robust and low-cost surgical microscope is created by incorporating commercial binoculars intended for close focusing into a housing having a contained mirror system providing both a diversion of the optical path and a reduced distance between the microscope and surgical site thus adapting these binoculars for ergonomic surgical application.
Claims17
A microscope system comprising:
- a binocular assembly including left and right eyepieces and corresponding left and right objective lenses separated by optical-path-folding left and right prism assemblies, the objective lenses receiving light along left and right axes;
- and
- a mirror assembly of at least two planar mirrors positioned along an optical path between the objective lenses and a corresponding focal spot at an operating site, the at least two planar mirrors operating with the binocular assembly to divert the angle of light received from the operating site to align with the left and right axes of the objective lenses.
A microscope system comprising:
- a binocular assembly including left and right eyepieces and corresponding left and right objective lenses separated by optical-path-folding left and right prism assemblies, the objective lenses receiving light along left and right axes;
- and
- a mirror assembly of at least two planar mirrors positioned along an optical path between the objective lenses and a corresponding focal spot at an operating site, the at least two planar mirrors operating with the binocular assembly to divert the angle of light received from the operating site to align with the left and right axes of the objective lenses;
- further including a second binocular assembly including left and right eyepieces and corresponding left and right objective lenses separated by optical-path-folding left and right prism assemblies, the left and right objective lenses receiving light along second left and right axes;
- further including a second mirror assembly of at least two planar mirrors positioned along an optical path between the objective lenses and corresponding focal spots at an operating site, the first and second planar mirrors cooperating with the second binocular assembly to divert the angle of light received from the operating site to align with the second left and right axes.

A binocular adapter system comprising:
- a housing providing a receptacle for receiving a pair of commercial off-the-shelf binoculars providing a binocular assembly including left and right eyepieces and corresponding left and right objective lenses separated by optical-path-folding left and right prism assemblies, the objective lenses receiving light along left and right axes, the receptacle including at least one stop for positively orienting the pair of binoculars to a predetermined optical axis;
- wherein the housing further supports a mirror assembly of at least two planar mirrors positioned along an optical path between the objective lenses and corresponding focal spots at an operating site, the first and second planar mirrors cooperating with the binocular assembly to divert the angle of light received from the operating site to align with the left and right axes by an acute angle.
