Main body of endoscope (for aural, rectal or urethral use). Unknown maker. c.1875-1885 CE.
A physician uses an endoscope to look into body cavities. This is to examine a patient and diagnose disease. Specialised endoscopes have different designs and names according to what part of the body they look at, for example the throat, rectum or bladder.
This endoscope comes with attachments, called specula. These are for aural, rectal or urethral use. An endoscope uses a light source, in this case a lighted wick, to illuminate the cavity via reflective surfaces. The light bounces off an angled mirror inside the endoscope. This projects the light and enables the physician to see into the body.
In 1865, British physician John Brunton (1835–1899) described using a modified endoscope or ‘auriscope’ to examine the ear. This instrument is a development of Brunton’s auriscope (see A647320).
