Surgical retractor

A surgical retractor comprising:

• a frame member;
• first and second retractor blades coupled to the frame member, the retractor blades having retraction surfaces configured to engage an incision in a patient's body;
• the retractor blades being relatively movable with respect to the frame member toward or away from the each other along a first axis to position the retractor blades closer or away from each other;
• at least one of the retractor blades being rotatable about a second axis which is generally perpendicular to the first axis;
• a rotational locking mechanism for selectively locking said at least one retractor blade against rotation about the second axis;
• a foot coupled to the frame member, the foot having a support surface configured to engage a surface of a patient's body;
• and
• an actuator for imparting relative movement to the retractor blades along the first axis.

A surgical retractor comprising:

• a frame member;
• first and second retractor blades coupled to the frame member, the retractor blades having retraction surfaces configured to engage an incision in a patient's body, wherein one of the retractor blades is movable with respect to the frame member along a first axis to position the retractor blades closer or away from each other;
• a foot coupled to the frame member, the foot having a support surface configured to engage a surface of a patient's body, wherein the foot and the frame member are adjustable in a linear direction along an axis which is transverse to the first axis;
• a locking mechanism for locking the foot and the frame member in a selected relative position along said axis which is transverse to the first axis;
• and
• an actuator for moving said at least one retractor blade with respect to the other retractor blade along the first axis.
