A videoscope, particularly adapted to examine the cervix, vagina or colon for cancerous lesions or other abnormalities, comprises a video camera unit (32) adjustable along a guide (34) attached to the fixed blade (10) of a speculum (10, 14). By using the videoscope in combination with a monochromator (54), the physician can step through various wavelengths of the light spectrum to test for fluorescence of abnormal cells. Channels (94, 98, 70) are for providing gas under pressure, for inserting forceps (100) and for providing suction to remove smoke created by the destruction of the cells by a laser beam. The video camera unit (32) can be inserted into a sterile sheath (88), and then attached to the speculum for insertion into the body passage for further examination. The video camera unit (32) can be removed from the sheath (88), resterilized or desinfected and reattached to a sterile speculum for use with another patient. |
