Surgical dilators designed for mechanically augmenting the caliber of the umbilicus to provide access to the abdominal cavity and intestines during surgical procedures. These surgical dilators typically consist of an instrument with an oblique distal end to facilitate placement and to displace tissue near angled surfaces. Umbilical surgical dilators are usually made of stainless steel or plastic latex -free material; they are available in a variety of sizes according to the surgical procedure to be performed. The dilators can be supplied as sterile and non-sterile instruments; some dedicated umbilical dilators are intended to provide arterial or vein access in neonates.
