The Cohen Uterine Cannula with 2 Cones is a specialized, reusable gynecological instrument designed for uterine manipulation, insufflation, and chromopertubation procedures. Its defining feature is a set of two interchangeable, cone-shaped tips that accommodate different patient anatomies and procedural requirements.

The two cones are typically a large and a small size. For example, the KARL STORZ system includes a large cone with a maximum insertion width of 25.0 mm and a small cone of 19.0 mm.
