Endoscope

Endoscopic neurosurgery (“channel” endoscopy) is mainly used in ventricle endoscopy. The neurosurgical instruments are introduced via working channels that are located within the endoscope.

The first endoscope is credited to Philipp Bozzini, a German physician, who demonstrated the “Lichtleiter”, a candlelit tube, in 1806 to the Academy of Medicine in Vienna 1). This was vastly improved in 1877 by Max Nitze, a German urologist, with the addition of lenses for magnification and an internal light source noting “to light up a room one must carry the lamp inside 2). ” His first endoscope used a water-cooled platinum wire for illumination but Edison's invention of the incandescent bulb in 1879 allowed the development of a cystoscope that no longer required water cooling. Using his invention, Nitze was the first person to perform endoscopic surgery with wire loops and to take endoscopic pictures. The next technological breakthrough occurred almost a century later when Harold Hopkins in 1960 vastly improved optical efficiency by inserting glass rods and neutral gas between the lenses. Around the same time, Basil Hirschowitz, an American gastroenterologist, developed a flexible endoscope using fiberoptics. The modern rigid endoscope was invented by Karl Storz in 1965 when he combined the optical rod system of Hopkins and used fiberoptics to carry illumination down to the tip of the endoscope 3).
