A medical video endoscope system for allowing high-resolution three-dimensional images to be viewed has a stereoscopic endoscope for converting optical images of an object to left and right video image signals. An electronic processor module controls the stereoscopic endoscope and processes the left and right video image signals into time-multiplexed signals representative of high-resolution three-dimensional images having stereoscopic depth. The time-multiplexed signals are provided to a monitor which displays high-resolution video images based on the signals. A viewing device is provided which allows a viewer to see high-resolution three-dimensional video images having stereoscopic depth on the monitor. A rigid sheath assembly with an angled distal tip can be placed over a barrel of the endoscope and rotated with respect thereto in order to change the viewing direction of the stereoscopic endoscope. A conventional two-dimensional endoscope can be coupled to the three-dimensional medical video system by using a camera head designed to convert the two-dimensional optical images generated by the conventional endoscope into left and right signals which are then processed by the system as if they were received from a stereoscopic endoscope to create a two-dimensional video image.

Stereoscopic endoscope system

An endoscopic device includes an endoscopic tube for insertion into a cavity to be viewed; an optical system including a video camera and illuminating means for viewing the cavity, the image on the screen being a noninverted image; and a removable, rigid, sterilizable or discardable sheath completely enclosing the endoscopic tube and the illuminating means to prevent their exposure to the cavity environment.

Endoscopic device

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.

Endoscopic device for intraoral use

A coaxial illuminator adapted for surgical coaxial illumination and viewing including an opaque housing defining a longitudinal axis and having a tilted, anti-reflection coated window located at one end of the housing. A beamsplitter is located within the housing and is positioned so as to reflect light, from a light source, along the longitudinal axis of the housing through the window to illuminate the object and to permit image light from the object being viewed to pass along the longitudinal housing through the beamsplitter. An absorber is positioned to absorb light which passes from the light source through the beamsplitter unreflected.
