A simple yet highly useful cervical videoscope has been provided which can easily be used by the doctor to examine the cervix and vagina far cancerous lesions or other abnormalities. Also, because of the small size of the video camera unit there is sufficient space between the video camera unit and the blades of the speculum for inserting forceps and other instruments that may need to be used. By using the cervical videoscope in combination with a monochromator the physician can step the wavelength of light from one end of the light spectrum to the other until he observes florescence which identifies abnormal cells. Thereupon, he can destroy the cells by use of a laser beam. When he observes that no more florescence is occurring, then he can discontinue the operation of the laser, knowing that the lesion has been completely eradicated. Also, a channel for drawing a suction to remove smoke created by the destruction of the lesion can be provided. The video camera unit also is adjustable along a guide on the fixed blade of the speculum to focus it. The video camera unit can be removed from the speculum and inserted into a sterile sheath for reinsertion into the vagina for examination for lesions and areas covered by the speculum blade. It can also be inserted into the colon and other body passageways where lesions are suspected. The video camera unit can be removed from the sheath, resterilized or disinfected and reattached to a sterile speculum for use with another patient.
