Abstract
Improved end effector mechanisms for a surgical instrument used in minimally invasive surgical instruments as well as instruments for general surgery or as part of robotically controlled end effectors. These end effector mechanisms include multiple grasping elements paired with drive links. Each grasping element also serves as a stabilizing link for the next most distal grasping element, forcing it to maintain its relative angle with respect to the opposing grasping elements.
