Transvaginal Single Access “Pure” NOTES Sleeve Gastrectomy Using a Deployable Magnetically Anchored Video Camera

Maximizing coupling strength of magnetically anchored surgical instruments: how thick can we go?

“…This contrasts with work described by other researchers, who have designed systems that appear to nicely provide liver retraction, but utilize a much larger external magnet [17,18], which may prove cumbersome. Indeed, the agility of our system has allowed us to perform a wide array of complex surgical tasks using magnetic instruments, including dissection, cauterization, optics delivery, as well as retraction [2][3][4][5][6][7][8][9][10][11].…”

“…This system includes deployable instruments (camera, light source, grasper, retractor, and cautery dissector) that are inserted into the abdominal cavity through a single access point (laparoscopically, NOTES or LESS) [2][3][4][5][6][7][8][9][10][11]. The internal components contain magnets and are manipulated by using an external magnet, which is held on the surface of the abdominal wall.…”

Tissue Compression Analysis for Magnetically Anchored Cautery Dissector During Single-Site Laparoscopic Cholecystectomy

“…Both our MAGS cautery dissector and camera instruments have proven valuable in facilitating NOTES and SSL procedures in animal models. 9,[11][12][13][14]17 More recently, we successfully used the MAGS camera for visualization during two SSL human cases (nephrectomy and appendectomy). 13 These reports document the utility of magnetically anchored instruments in overcoming numerous hurdles associated with limited access approaches.…”

“…Numerous reports of animal and human work using magnetically anchored instruments have not documented any adverse tissue effects during the use of available instruments. [8][9][10][11][12][17][18][19][20][21][22]24 However, there has been very little work done to document the safety of these instruments from a histological perspective. It is this paucity of literature that has driven our group to explore these areas and publish our findings.…”

“…in either a NOTES or SSL environment. 11,12 By coupling the instruments across the abdominal wall, an otherwise occupied access port is freed for use by other instruments. Angles needed to perform dissection (sharp or blunt) can be attained even with associated space constraints of current platforms.…”
