Abstract
Abstract A method and apparatus for creating a surgical work space by lifting the abdominal wall and retracting abdominal organs during surgery utilizes a pair of lifting rods each hinged at their distal ends to opposite ends of an elongate cross-member. One of the lifting rods is slidable within a strap fastened to the proximal end of the other of the rods. The hinged relation of the lifting rods to the cross members and the sliding relation of the lifting rods to each other allow the apparatus to be pivoted into a streamlined configuration to facilitate insertion into a puncture opening in an abdominal cavity, and then to be pivoted into a triangular frame for defining an area of the abdominal wall to be lifted. After insertion the apparatus is locked into the triangular configuration, connected to a lifting arm, and lifted to cause the retraction rods to lift and support the abdominal wall.
