Handheld portable examination device for diagnostic use

A medical examination device for spectral detection of cancer having:

• an illumination source;
• a first lens unit conditioning a light beam from the illumination source;
• an excitation optic fiber delivering conditioned light beam from the first lens unit to a tissue to be examined;
• an image optic fiber receiving a light beam emanating from a tissue illuminated with a conditioned light beam and transmitting a emanated light beam through a second lens unit;
• and
• a viewing assembly having
• a pivotable linkage including a first side having a first and second link and a second side having a first and second link,
• a first lens holder mounted on a proximal end of the second link of the first side and a proximal end of the second link of the second side,
• a second lens holder mounted on a distal end of the first link of the first side and a distal end of the first link of the second side,
• a pivoting mechanism interconnecting the first and second sides of the pivotable linkage wherein the pivoting mechanism allows an operator to adjust a angle of the first lens holder in relationship to the second lens holder, and
• a mirror carrier having a mirrored surface rotatably supported by an interior end of the first and second links of the first and second sides proximal the pivoting mechanism, wherein the first lens holder is held in an aligned position that is coaxially aligned with the second lens unit while the mirror carrier and the second lens holder are angularly adjustable about the aligned position;
• and
• whereby the emanating light beam passing through the second lens unit is directed through the viewing assembly.

• an image optic fiber receiving a light beam emanating from a tissue illuminated with a conditioned light beam and transmitting the emanated light beam through a second lens unit;
• a beam splitter that splits the emanated light beam from the second lens unit into a first light beam and a second light beam;
• an image capture device for selectably capturing the first light beam;
• and
• a viewing assembly having
• a pivotable linkage including a first side having a first and second link and a second side having a first and second link,
• a first lens holder mounted on a proximal end of the second link of the first side and a proximal end of the second link of the second side,
• a second lens holder mounted on a distal end of the first link of the first side and a distal end of the first link of the second side,
• a pivoting mechanism interconnecting the first and second sides of the linkage between the first and second lens holders wherein the pivoting mechanism allows an operator to adjust the angle of the first lens holder in relationship to the second lens holder, and
• a mirror carrier having a mirrored surface is rotatably supported by an interior end of the first and second links of the first and second sides proximal the pivoting mechanism, 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;
• and wherein the second light beam is directed through the viewing assembly to a lens mounted in the second lens holder for visualization of the second light beam by the operator.
