<p>A simple yet highly useful cervical videoscope (V) has been provided which can easily be used by the doctor to examine the cervix for cancerous lesions or other abnormalities. Also, because of the small size of the camera there is sufficient space between the camera and the blades of the speculum (S) for inserting foreceps and other instruments that may need to be used. By using the cervical videoscope (V) 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 fluorescence which identifies abnormal cells. Thereupon, he can destroy the cells by use of a laser beam. When he observes that no more fluorescence is occurring, then he can discontinue the operation of the laser, knowing that the lesion has been completely eradicated. Also, a channel (70) for drawing a suction to remove smoke created by the destruction of the lesion can be provided. Finally, the camera is adjustable along a guide (34) on the fixed blade (10) of the speculum (S) to focus it.</p> |
