A standard Hank Uterine Dilator Set of 6 is a comprehensive, reusable gynecological kit containing six double-ended, surgical-grade stainless steel dilators. They provide 12 total size increments to safely and progressively widen the cervical canal. Each instrument is 26.5 cm to 27 cm (10 1/2" to 11") long and features slightly curved, tapered tips with built-in depth stops to minimize the risk of uterine perforation.
