Claim 9:
10. 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 retraction elements comprising alternating pairs of small ramps and large ramps,
wherein each pair of the small ramps have a first ramped tooth and a second ramped tooth such that both teeth increase in height from a first end to a second end,
wherein each pair of the large ramps has a first ramped tooth and a second ramped tooth such that both teeth increase in height from a first end to a second end, and
wherein the first end of the small ramps are adjacent the second end of the large ramps such that the small ramp pairs and large ramp pairs face in opposite directions.
