First Claim
Patent Images
1. A uterine sound comprising:
- an elongated probe having a distal end and a proximal end, measuring indicia scribed thereon between said distal and proximal ends and an integral, raised first rib extending substantially the length thereof; and
an elongated body having a distal end and a proximal end mounted on said probe, said body being of horsehoe-shaped cross-section and having inwardly curved sides, at least one of said sides encompassing said first rib and cooperating therewith to retain said body on said probe at a first position whereat said body is parallel to the longitudinal axis of said probe and is slidably moveable along said probe, and said cooperating side being adapted to engage said first rib and cooperate therewith to hold said body on said probe at a second position whereat the proximal end of said body is displaced from said probe and said body is restrained from slidably moving along said probe.

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.
