We designed a method for remote-controlled endoscopic surgery using magnet-retracting forceps. To evaluate the feasibility of this technique, laparoscopic cholecystectomy was attempted in a swine model. This method takes advantage of the attractive force between two magnets, one inserted into the peritoneal cavity and the other located outside the abdominal wall. An intra-peritoneal magnet was fixed to the fundus of the gallbladder using an endovascular clip. Laparoscopic cholecystectomy was accomplished by magnetic retraction of the gallbladder. This magnet-retracting forceps provided port-less access to the abdominal cavity. Since the direction and range of retraction were unrestricted by the location of access-ports fixed on the abdominal wall, surgery could be less invasive. In addition, this procedure provided surgeons with excellent endoscopic views, as retraction force was supplied without any shaft device in the abdomen. This operation system using magnetic retraction appears promising.
