The 6 3/8" Freer Septum Knife (E Model) is a specialized surgical instrument used in ENT surgeries, particularly for septoplasty and other nasal procedures. The E model typically refers to a specific design or style of the Freer Septum Knife, known for its precision cutting capabilities. The knife is designed to dissect and separate tissue with minimal trauma to the nasal septum, making it ideal for removing obstructive tissue, reshaping the septum, or preparing the area for further reconstruction.
