The Perkins Retractor (Blade Rig 3 Blunt Prongs, Left, Self-Retaining) is a surgical instrument designed for use in otologic and other microsurgical procedures. It features a left-facing blade with 3 blunt prongs, which are used to gently retract tissues and structures, providing better visibility and access to the surgical site. The self-retaining mechanism allows the retractor to stay in position without continuous manual adjustment, helping to free the surgeon’s hands during the procedure.
