1. A surgical retractor, comprising:
a distal end comprising a handle extending longitudinally to form a neck;
a proximal end comprising a blade, where the blade comprises two or more curved fingers, where terminal ends of each finger project in a distal direction towards the handle;
a releasable lock located at a proximal end of the neck, where the releasable lock is configured to allow for the removable attachment of the blade to the neck; and
a textured surface formed on an inside top surface of each finger, where the textured surface comprises a tightly meshed anisotropic pattern of retractor elements that terminate before the terminal ends of each finger such that the terminal ends minimize tissue trauma and preserve glove integrity,
wherein the anisotropic pattern comprises a repeating pattern of retraction elements where a first group of retraction elements overlaps back walls of a second group of retraction elements.
