Abstract
Abstract A surgical stay apparatus provides a frame that can be annular and conforming to a patient's body at a surgical site. An opening allows a surgeon to access the surgical site through the central portion of the frame. A stay includes a handle body having proximal and distal ends. The first bore extends through the handle body communicating at least with the proximal end of the handle body. The second bore extends at least a partial distance through the handle body and communicates with the proximal surface of the body. An elastic member extends through the first bore, the elastic member having an elongated portion that extends from the distal end of the handle body and a short proximal end that is positioned at the handle body occupying at least a portion of the first bore. A hook member having proximal and distal end portions occupies the second bore of the handle body, the hook member has a curved hook at the distal end portion of the handle body for retracting body tissue. The handle body can be of an injection molded plastic construction. The elastic member can be an elongated section of hollow silicone tubing. The hook can be shaped to snap into one of the bore of the handle body for anchoring the hook to the handle body. In one embodiment, a plastic injection molded stay handle can have a "V" slot to retain the distal end of the elastic tubing.
