Abstract
A surgical tool for minimally invasive surgery. The surgical tool in one embodiment includes a manipulator as a user interface, a proximal universal joint mounted to the manipulator, a hollow elongated member such as a tube mounted to the proximal universal joint, and a distal universal joint mounted to the other end of the elongated member. An end effector is mounted to the distal universal joint second end. Pivoting of the first end of the proximal universal joint causes the second end of the distal universal joint to move in a corresponding motion, and cabling operatively couples the proximal and distal universal joints. The proximal and distal universal joints may each include two yokes and a center block. Cabling may include four cables that each engage two round elements at the proximal and distal universal joints mounting locations to the center block.
