In 1868, Bevan used an esophagoscope to remove foreign bodies in the esophagus. The following year Pantaleoni used a hysteroscope to find a polyp in an old woman's womb and cauterized it with chemical reagents. The German doctor Kussmaul was inspired to watch a sword swallowing performance by a Jianghu artist. He chose a straight metal tube about half a meter long and more than 1 cm in diameter, and made a hard tube mirror with a little equipment. With the cooperation of the artist, Kussmaul inserted the hard tube into the stomach through the artist's mouth, but failed due to insufficient lighting.

He can be regarded as the first person to use an internal light source. Bruck later developed a water-cooling device. In order to avoid burning the tissue with the overheated platinum wire.
