The W.M. is a customized version of the traditional Deaver retractor. For deep abdominal, pelvic, or thoracic procedures, the Lemmon Extra Deep model is made to provide the most exposure possible. Its 15 1/2" length allows for deep retraction and extended reach while preserving tissue integrity. It is made of premium surgical stainless steel for strength, corrosion resistance, and complete sterilization compatibility, making it perfect for procedures that need access to difficult-to-reach areas.
