<p>Disclosed is a self-retaining surgical retractor (10) suitable for use in small surgical incisions or punctures, able to expand the incision or puncture to one or more enlarged cross-sectional areas and designed to protect the edges of the incision or puncture. The surgical retractor (10) comprises a radially expandable tubular body (20) having a control (60) at the proximal end (22). Pull wires (100) couple the control (60) to the tubular body (20) such that force applied to the control (60) is transmitted to the tubular body (20) as axially compressive force.</p> |
