Abstract
Abstract The present invention provides a surgical grasper device that comprises a generally elongate housing member having a handle member at a proximal end and first and second grasping arms at a distal end. First and second grasping elements are preferably releasably attached to the first and second grasping arms respectively. The grasping elements are positioned on the arms in an opposed facing relationship to enable grasping a targeted surface such as living tissue between the elements. A gripping material at least partially covers or is otherwise incorporated into the surface of one or both of the grasping elements. The gripping material provides enhanced holding power to the targeted surface relative to the holding power provided by the grasping elements in the absence of the gripping material.
