ABSTRACT:
A uterine sound is described having a probe with measuring indicia inscribed thereon and a horseshoe-shaped body slidable along said probe and cooperative therewith for measurement of uterine position and dimension. A raised rib is located along a substantial length of the probe to normally retain the horseshoe-shaped body in parallel alignment with the longitudinal axis of the probe. When the body is displaced from parallel alignment with the probe, the rib interacts with the body to fix the body relative to the probe, and permit withdrawal of the probe and body as a unit. An internal stop mechanism is employed to prevent excessive movement of the body relative to the probe.
