Abstract
A tool apparatus and a method for actuating a tool apparatus are disclosed. The tool apparatus includes an actuator housing, and an elongate tool manipulator extending outwardly from the actuator housing and having a plurality of control links extending along a length of the tool manipulator. The control links are operable to cause movement of a distal end of the tool manipulator in response to movement of the control links in an actuating direction generally aligned with the length of the tool manipulator. The apparatus also includes a plurality of actuators, each actuator being associated with at least one of the control links and being mounted in the actuator housing to facilitate a range of travel in a transverse direction substantially orthogonal to the actuating direction, and a plurality of linkages. Each linkage is associated with one of the control links and extends between the control link and the respective actuator and is operable to transmit drive forces between the actuator and the control link.
