Abstract:
1. A medical examination device for spectrally screening tissue for cancer having: an illumination source transmitting a light beam through a first lens unit to condition the light beam; a fiber optic bundle including an excitation fiber and an image fiber, wherein the excitation fiber delivers the conditioned light beam from the first lens unit to a tissue to be examined and wherein the image fiber directs a light emanating from an illuminated tissue to a second lens unit; an angularly adjustable visualization unit having a pivotable linkage with a first lens holder mounted on a first end of the pivotable linkage, a second lens holder mounted on a second end of the pivotable linkage, a pivoting mechanism positioned between the first and second ends of the linkage that allows an operator to adjust an angle of the first lens holder in relationship to the second lens holder, and a mirror rotatably supported by the pivotable linkage proximal the pivoting mechanism such that a light beam conditioned by the second lens unit passes through the angularly adjustable visualization unit and is visualized by the device operator through a lens mounted in a second lens holder and wherein the first lens holder is held in an aligned position that is coaxially aligned with the second lens unit while the mirror and the second lens holder are angularly adjustable about the aligned position.
