Abstract
A method and apparatus for creating a surgical work space by lifting the abdominal wall and retracting abdominal organs during surgery utilizes a lifting body having two or more retraction rods supported by the lifting body. The rods are designed to be introduced into the abdominal cavity through a laparoscopic puncture opening and to be extended within the abdominal cavity to provide a lifting area. In the preferred embodiment, a pair of retraction rods disposed with the bores and substantially parallel to each other are inserted into the abdominal cavity through an incision in the abdominal wall. The retraction rods are spread apart from each other while their parallel orientation is maintained. The lifting body is connected to a lifting arm and lifted, causing the retraction rods to lift and support the abdominal wall.
