Abstract
A manipulator adapted to grasp and draw tissue comprises first and second arms having proximal ends and distal ends separated by a distance. First and second grasping surfaces each connected to and extending from respective distal ends of the first and second arms are biased toward each other by a respective spring force. When the first and second arms are actuated to reduce the distance, the manipulator is configured such that tissue arranged between the first and second grasping surfaces resist actuation of the first and second arms. The first and second arms are further actuatable to overcome the spring force of the first and second grasping surfaces so that the first and second grasping surfaces pivot at respective pivot points such that the distance between the distal ends of the first and second arms is reduced.
