The Iron Intern® Retractor, which mimics the human arm, is of much utility in General, Bariatric, and Transplantation Surgery. It is well adapted for laparoscopic surgery with the Grippers which are designed to hold laparoscopic instrumentation. When conversion to laparotomy is necessary, the retractor is of equal utility in providing exposure.”

Dr. Robert Greenstein

I’ve been using the Iron Intern® Stieber Rib Grip  for the last 25 years.  In our OR, it’s been commonly known as “The Big Boy.”  I have been utilizing it for Bariatric, Hepatobiliary, and Foregut surgery, including Whipple, Esophagectomy, Liver Resections, Gastric Resections and Trauma. I haven’t seen a retractor with better exposure than the Stieber.”
