Retrieval system for facilitated and safe extraction of resected specimen in minimally-invasive surgery

The benefit of using retrieval systems in minimally-invasive surgery is to facilitate the removal of operative specimen, while minimising the contamin ation of the peritoneum and port-sites in the abdominal wall. We have devel oped an innovative retrieval system with a mechanism of action and design t hat differs widely from other devices. Its increased functionality is achie ved by combining it with a laparoscopic instrument: the resected tissue is wrapped in plastic foil, rather than being entrapped in a bag. During deliv ery through the abdominal wall, permanent traction is exerted on the specim en and thus obstruction in the port-site is avoided. The retrieval system h as been tested for impermeability and proven to be safe and able to avoid s pillage of cells.
