An application of television to the demonstration of operative surgery

The paper discusses the provision of television equipment for viewing surgical operations in teaching hospitals. After considering the specific conditions which prevail in an operating theatre, the description of a particular television equipment demonstrates an approach to these problems. Electrically this design follows closely that used in a standard 405-line camera channel employed with the C.P.S. Emitron. The novelty of the unit lies chiefly in the mechanical and optical features of the camera and lighting apparatus, and these are treated in greater detail. The paper concludes with a critical review of the value of television as a teaching aid and of the possibilities for its future development, based on extensive experience of the equipment in the Department of Surgery, Guy´s Hospital, London.
