Grasping Contact Analysis of Tissues With Semi-Cylindrical Teeth Grasper for Minimally Invasive Surgery Applications

This study presents both numerical and analytical methods to determine the contact pressure on the surface of tissues being grasped by an endoscopic grasper with semi-cylindrical teeth, in Minimally Invasive Surgery (MIS). It is highly important to avoid damage to the tissues during grasping and manipulation by endoscopes. Therefore, it is essential to determine the exact contact pressure on the surface of the tissue.Copyright © 2007 by ASME
