“…This method is extremely effective; however, insertion of the anvil into the colon is rather complex. Uematsu et al [41] reported another SILS technique that uses movement of an extracorporeal magnet to retract the tissue grasped by a magnetized intracorporeal short vascular clip. This interesting method allows mesenteric dissection to be facilitated by effective countertraction; however, it requires the use of a special sterilized magnet.…”

“…Single-incision laparoscopic techniques have been utilized in most colorectal procedures for which standard laparoscopic techniques are used, including right and left colectomy, sigmoid colectomy, low anterior resection, and total proctocolectomy [11][12][13][14][15][16][17][18]. The most frequently reported single-incision operation in colorectal surgery has been right hemicolectomy.…”

“…The Hospital de Clínicas in Buenos Aires has reported the clinical use of magnetized instruments (NdFeB) for single site laparoscopy [15], [16]. Clinical investigation of single-port laparoscopic colectomy was demonstrated to be safe and effective with the aid of magnetic retraction by Uematsa et al [17] while single site laparoscopy investigations by Cho et al have been limited to canine ileocecectomy (resection of the lower small intestine) [18]. In one of the only clinical examples of an electromagnet used for coupling, Kobayashi et al [19] demonstrated the use of the Pentax-developed magnetic anchoring system.…”

Citation information: DOI 10.1109/TBME.2014.2366032, IEEE Transactions on Biomedical Engineering TBME-00722-2014.R2 1Abstract-The use of magnets for anchoring of instrumentation in minimally invasive surgery and endoscopy has become of increased interest in recent years. Permanent magnets have significant advantages over electromagnets for these applications; larger anchoring and retraction force for comparable size and volume without the need for any external power supply. However, permanent magnets represent a potential hazard in the operating field where inadvertent attraction to surgical instrumentation is often undesirable. The current work proposes an interesting hybrid approach which marries the high forces of permanent magnets with the control of electromagnetic technology including the ability to turn the magnet off when necessary. This is achieved through the use of an electropermanent magnet, which is designed for surgical retraction across the abdominal and gastric walls. Our electropermanent magnet, which is hand-held and does not require continuous power, is designed with a centre lumen which may be used for trocar or needle insertion. The device in this application has been demonstrated successfully in the porcine model where coupling between an intraluminal ring magnet and our electropermanent magnet facilitated guided insertion of an 18Fr Tuohy needle for guidewire placement. Subsequent investigations have demonstrated the ability to control the coupling distance of the system alleviating shortcomings with current methods of magnetic coupling due to variation in transabdominal wall thicknesses. With further refinement, the magnet may find application in the anchoring of endoscopic and surgical instrumentation for minimally invasive interventions in the gastrointestinal tract.
