摘要

The retractor for laparoscopic surgery performed in the peritoneal cavity is given the form of a balloon (1) fitted with an insufflation/desufflation conduit (2), where upon insufflation the balloon (1) has the shape of a hollow cylinder, ring-shaped in cross-section, and before insufflation it is accordion-folded towards the balloon (1) axis and the fold is curled around the balloon (1) axis. The balloon (1) is made of a thin-wall plastic polymer material, preferably modified nylon or duraline. Preferably, the retractor is disposable.
