Abstract
Certain embodiments provide surgical retractors that include an arm and a blade, the arm including an opening and a first notched surface comprising a plurality of notches that extend radially outward from the opening, the blade including a nipple and a second notched surface comprising a plurality of notches that extend radially outward from the nipple. Attaching the blade to the arm such that the notched surfaces mate can secure the blade relative to the arm such that the blade cannot swivel radially about the opening. Certain embodiments provide methods for securing a retractor blade that can include inserting a nipple on a retractor blade into an opening and mating a first notched surface comprising a plurality of notches that extend radially outward from the opening with a second notched surface comprising a plurality of notches that extend radially outward from the nipple.
