Uterine sound, single-use

A uterine sound, single-use, is a sterile, hand‑held instrument that clinicians use to measure or explore the internal depth of the uterus, cervix, and vagina during gynecologic examinations. It is a slender cylindrical tool, often made of metal or plastic, and marked with length graduations to provide accurate sizing.

These devices are supplied sterile for one‑time use and are regulated as medical devices that must meet applicable safety and sterility standards. They are typically offered in a range of sizes and flexibilities to suit different clinical needs.
