The Sklar Kristeller Vaginal Speculum and Retractor Set are used in OB/GYN procedures. They are commonly used for visual examinations because both are handheld, manual, non-locking instruments. This set includes a 90mm x 36mm speculum and a 100mm x 32mm retractor. The sides of the speculum blade are curved upward slightly. The retractor has a smooth, flat blade. Both feature a slight hook at the bottom of the handle for pulling.
