Abstract
A retractor system, kit and method of use includes a plurality of retractors for use in retracting a wound during a minimally-invasive hip replacement surgery to define an access space to a surgical site is discussed. Each of the retractors comprises a handle portion configured to be held by a user, a curved bend portion distal of the handle portion, and a wound contact portion attached to the curved bend portion. The wound contact portion is configured to contact tissue of the wound when at least a portion of the retractor is inserted through a skin incision that defines the wound. Each retractor also has a distal portion disposed distally of the wound contact portion, wherein the wound contact portion has a generally curved cross-sectional profile perpendicular to its length that is configured to prevent necrosis of the tissue during retraction. In addition, the cross-sectional profile provides an improved line of sight during the surgical procedure. Furthermore, the cross-sectional profile prevents the jamming of a cutting device, such as a reamer inserted through the incision, while the retractors retract the wound.
