ABSTRACT:
An apparatus for allowing two retractors, preferably fan retractors, to be used to lift the abdominal wall to provide improved visualization and working space in the abdomen of obese patients, and in the lateral regions of the abdomen of normal patients. The apparatus connects a first retractor and a second retractor to a mechanical lifting arm, and comprises a bar, and first, second, and third connecting devices. The first and second connecting devices are each slidably mounted on the bar, are each lockable to the bar, and connect the first retractor and the second retractor, respectively, to the bar. The third connecting device is attached to the center of the bar and connects the bar to the mechanical lifting arm. The apparatus is used by making a first incision and a second incision in the abdominal wall at separated locations. The first retractor is inserted into the first incision, and the second retractor is inserted into the second incision. The first retractor and the second retractor are attached to the crossbar, anal a lifting force is applied to the crossbar.
