Abstract
Natural Orifice Translumenal Endoscopic Surgery (NOTES) is a type of minimally invasive surgery. This surgery needs working space when the surgeon operates endoscope in body cavity. We have been developing a surgical tool system that can make the space and is less-invasive for patient. In this paper,we had formulated new abdominal wall lifting method using magnets and supplementary tool. We use electro magnet outside the body and neodymium magnet inside of body cavity to fix abdominal wall when surgeon lifts it. Also, supplementaly tool is used in body cavity with neodymium magnet to keep abdominal wall. And we had experimented the adsorption force of magnets as to thickness. Experimental results indicated that this force decreases in an exponential manner and secures it until thickness of 6-millimeter.
