IPA: /lɪˈθɒtrɪptə/
KK: /lɪˈθɑːtrɪptər/
A device used in medical procedures to break down kidney stones into smaller pieces so they can be passed more easily.
The doctor used a lithotriptor to treat the patient's kidney stones.
Lithotriptor → It is formed from "litho-" (from Greek "lithos", meaning stone) and "triptor" (from Greek "tripsis", meaning to crush). The word "lithotriptor" refers to a device that crushes stones, particularly in the medical context of breaking down kidney stones.
Think of 'stone' ('lithos') being 'crushed' ('tripsis') — that's what a lithotriptor does, it crushes stones.
