ABSTRACT A heat sterilizable electronic video endoscope is provided in which a lens system is mounted by the use of elements such as metal spacers, which are not adversely affected by heat. Similarly, the electronic circuitry is arranged in the center of the endoscope and is formed of heat resistant material. In addition, glass fibers are provided which surround the lens system and the electronic circuitry to further protect it from the heat of sterilization. The light fibers themselves are made of glass and are not adversely affected by the heat sterilizing process. In addition, a sterilizable sheath may be provided which will extend over the endoscope and has an accordion shaped extension to extend along the electrical cable and light cable for those situations where it is not possible to resterilize the endoscope for a second procedure. In addition, a removable handle can be provided over the sheath which facilitates positioning the endoscope during an operative procedure or investigation.
