An oral cancer screening device 10 used for the detection of pre-cancerous and cancerous tissue has a power supply 100 , an illumination source 200 , a selector switch 300 that enables the activation of a specific wavelength of light from the illumination source 200 , an electrical system 400 in communication with the selector switch 300 and the illumination source 200 , a heat sink 500 in thermal communication with the illumination source, a filter or cover 600 to protect the illumination source, and a transparent sheath 700 for providing a sanitary shield for the device when it is brought into contact or close proximity with the patient oral cavity. The sheath may optionally have an angled mirror incorporated at a distal end of the sheath to provide the operator with a reflected image of the illuminated tissue 900 . The operator will optionally utilize head mounted lenses 800 to assist the operator's visualization of the light from the illuminated oral cavity. |
