SURGICAL RETRACTOR
A surgical retractor includes a blade and a handle. The blade has a top surface and a bottom surface. The handle extends at an angle from a proximal end of the blade. In one exemplary aspect, the retractor has one or more slip-resistant patterns molded into the blade, in order to prevent slippage of the retractor against patient tissue.
