Abstract: A surgical retractor device has a housing with press arms coupled thereto, each arm having rotational movement in a plane, and a gripping member pivoting at right angle with the plane, at an outer end of the arm; an attachment means at an inner end of the arm; an opening and closing mechanism with rotatable press arm attachment structures attaching the attachment means of the press arms, symmetrically positioned from a centerline of the device; rotatable handle attachment structures, and; a transfer mechanism transferring rotation from handle attachment structures to press arm attachment structures. The device also has handles for operating the opening and closing mechanism. Each handle has a handle attachment means at an inner end of the handle for attachment to the handle attachment structures; and, a handle structure. The handles have a rotational movement in the plane and are symmetrically positioned from the centerline of the device.
