Operating microscope

The surgical microscope is an applied in minimal invasive surgery and microsurgery microscope with comparatively low magnification (about 6 - to 40-fold ), and provides an upright, three-dimensional image. The magnification goes beyond the magnifying glasses. It comes in the medical field for almost all operating directions are used.

History

The surgical microscope was first used by Carl Olof Nylen Siggesson at a oto- rhino - laryngological intervention in September 1921. 1922 modified Nyléns boss and teacher G. Holmgren ( 1875-1954 ) a binocular microscope from Carl Zeiss by adding a light source and a state apparatus in order to use it in Fenestrationsoperationen. In 1950 it was introduced in ophthalmology. Horst Ludwig Wullstein built, dissatisfied with the then established, rigid Dissektionsmikroskopen, a private, significantly more mobile surgical microscope.

Advantages over the loupes

Compared to the magnifying loupe is a higher magnification (up to 40 - instead of 2 to 7- fold). Furthermore, there is a quieter operation field, as head movements do not interfere with the field of view and the surgeon and the assistant see the same operational area under magnification without having to come up with the head too close to the surgical site. Unlike a magnifying loupe view and lighting follow an almost identical beam path, which is reflected in a much better illumination of the surgical field. In addition, documentation of the operation and the transmission of the operation field on the other monitors is possible.

Special supplements

The settings of the microscope can be made with footswitches. The microscope can be covered with a special sterile film ( Draper ), which does not interfere with the view, but allows for aseptic working.

Manufacturer

Operating microscopes are, inter alia, from Zeiss, Leica Microsystems, Möller- Wedel and capes made ​​optics.
