The utility model provides a general stereo microscopic shooting and demonstrating device used for surgical operations. The device is composed of a 3D high-definition digital camcorder, a c and an adjusting support. The small-size integrated 3D high-definition digital camcorder is adopted. A microscopic adapter, a microscopic camera lens and a focusing light source are added in front of a lens of the small-size integrated 3D high-definition digital camcorder and are fixed with the bed-side-type, a suspension-type or a floor-type adjusting support and connected with the small-size integrated 3D high-definition digital camcorder. The microscopic lens is a single lens or is composed of multiple lenses and the focal length is 250mm to 500. The focusing light source is a cold light source connected through light conducting fibers or an LED light source whose front end is equipped with a condensing lens having a consistent optical axis focus with a 3D camera lens. The general stereo microscopic shooting and demonstrating device used for surgical operations provided by the utility model is small in size, low in weight and convenient to carry and also has functions of operation illumination, 3D real-time high-definition camera shooting, image recording, voice recording, displaying, image transmission and the like at the same time. The general stereo microscopic shooting and demonstrating device used for surgical operations is suitable for applying to multidisciplinary microscopic operations and regular open operations in surgical systems.
