Abstract
The benefit of using retrieval systems in minimally-invasive surgery is to facilitate the removal of operative specimen, while minimising the contamination of the peritoneum and port-sites in the abdominal wall. We have developed an innovative retrieval system with a mechanism of action and design that differs widely from other devices. Its increased functionality is achieved by combining it with a laparoscopic instrument: the resected tissue is wrapped in plastic foil, rather than being entrapped in a bag. During delivery through the abdominal wall, permanent traction is exerted on the specimen and thus obstruction in the port-site is avoided. The retrieval system has been tested for impermeability and proven to be safe and able to avoid spillage of cells.
