Abstract
An inta-oral device for viewing the oral cavity comprises a handle having a tube extending therefrom for insertion into the oral cavity to be viewed; an optical system within the tube; a video camera within the handle and illuminating means for illuminating the cavity; and a removable, rigid, sterilizable sheath completely enclosing the tube and illuminating means to prevent their exposure to the oral cavity. The optical means provides a non-reversed image to appear on a video screen.
