The behavior of sucking disks, used to stabilize human tissue during surgeries, was investigated using conventional plastic sucking disks. The contact load to control a sustainable tangential load was calculated from the pressure and area of the internal cavity and the normal load. We observed an interesting phenomenon wherein the more the disk was pulled, the more it was pressed against the counter-surface. We also investigated the maximum tangential frictional force for several pre-loads applied perpendicularly to clarify the potential for sticking. We found that higher the pre-load, the lower was the maximum tangential friction force obtained.
