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.
我们设计了一种使用磁力回缩钳进行远程控制的内镜手术方法。为评估该技术的可行性，我们在猪模型中尝试了腹腔镜胆囊切除术。该方法利用了两块磁铁之间的吸引力，一块插入腹腔，另一块位于腹壁外。使用血管夹将腹腔内的磁铁固定在胆囊底部。通过对胆囊进行磁力回缩完成腹腔镜胆囊切除术。这种磁力回缩钳提供了无需端口进入腹腔的途径。由于回缩的方向和范围不受固定在腹壁上的进入端口位置的限制，手术的侵入性可能更小。此外，由于在腹部没有任何轴装置提供回缩力，该手术为外科医生提供了极佳的内镜视野。这种使用磁力回缩的操作系统似乎很有前景。
