Abstract
A laparoscopic surgical retractor has a substantially rigid insufflation tube insertable through a laparoscopic trocar, a valve for introducing fluid or gas into one end of the tube, and an elastic skin enclosing a variable volume cavity connected to the opposite end. During laparoscopic surgery, the retractor is inserted into a body cavity through a laparoscopic trocar, and then the elastic skin is inflated through the insufflation tube. The elastic skin is positioned against the tissue to be retracted. The retractor may either be held in place by the laparoscopic trocar, or else fully inserted into a body cavity and held in place by its own weight. Following the surgical procedure, the elastic skin is deflated and the device removed through the trocar.
