    摘要： An inflatable retraction apparatus is provided for retracing an organ inside a body to gain access to an adjacent tissue. The apparatus includes an able chamber formed from a single thin envelope, and capable of being collapsed for insertion through an incision and being expanded to a predetermined shape for retracing the organ. An inflation mechanism is adapted to selectively inflate the chamber to the predetermined shape. The inflation mechanism includes at least one inflation tube attached to the inflatable chamber in fluid communication theretween, and an inflatable maintaining lattice operatively enveloping the inflatable chamber and in operative association with the inflation mechanism. The inflatable maintaining lattice defines a plurality of single layered access windows around the inflatable chamber, and is configured and adapted to maintain the inflatable chamber in substantially the predetermined shape after an aperture is pierced in at least one of the plurality of access windows of the inflatable chamber.

    摘要： Retraction of an organ or tissue plane to be retracted is performed to gain access for a surgical instrument to treat an organ or tissue plane to be treated. An inflatable retractor, including a main envelope enclosing a main chamber, is provided with the main envelope in a collapsed state. The main envelope of the retractor is placed adjacent the organ or tissue plane to be retracted. The main chamber is inflated to an expanded state to retract the organ or tissue plane to be retracted. An aperture is pierced in the main envelope to provide access for the surgical instrument passed into the main chamber to contact an organ or tissue plane to be treated while the main chamber is maintained in the expanded state, notwithstanding the aperture pierced in the main envelope. The organ or tissue plane to be retracted and the organ or tissue plane to be treated may be different parts of the same organ or tissue plane. The method may be used in procedures including retracting the bowel to provide anterior access to organs, including the spinal column, the aorta and the kidneys, lying outside the peritoneum; retracting one part of the lung to provide access to another part of the lung; retracting the pericardium from the heart to provide access to the outer surface of the heart; retracting the liver to provide access to the gastro-esophagal junction; and retracting the brain from the dura mater to provide access to the brain.
