a wooden tube born because a doctor felt awkward pressing his ear to a woman's chest
means a medical instrument doctors use to listen to the sounds inside your body — heart, lungs, gut — usually two earpieces, a flexible tube, and a chest piece.
from From the Greek 'stethos' (chest) and 'skopein' (to look at, examine) — literally a 'chest-examiner.' The name was coined in early 19th-century France by physician René Laennec, who also invented the device itself: famously, he rolled up a sheet of paper into a tube to listen to a patient's heart, then refined it into a hollow wooden cylinder. The 'skopein' root, oddly, means 'to see' rather than 'to hear' — it's the same root lurking in 'telescope' and 'microscope.'
