Abstract

Minimally Invasive Surgery (MIS) needs continuous tool design innovation to support and facilitate the complex task executions of surgeons. In this article, an easily deployable magnetic structure design is presented, which is developed to retract the liver during MIS procedures. During the concept designing phase, a most critical research question, the stability of magnetic anchoring was investigated and analyzed through various experiments. The clinically relevant pulling forces have been applied to N52 neodymium magnets in different size, shape and arrangement to derive the maximum force certain retractor designs could withheld. The numeric results confirmed that the distributed load arrangement would be able to perform a stable human liver retraction. Magnetic encoring technology could have a significant future, encouraging other researchers to investigate the potential of magnetic tissue retraction in MIS procedures that could lead tothe development of specialized tools for human clinical deployment.
