Abstract
A system for performing multi-tool minimally invasive medical procedures through a single instrument port into a body cavity includes a rigid tube carried by a mount. Cannulas having instrument channels and steerable distal ends extend distally from the rigid tube. During a procedure using the system, the mount is supported by an operating room fixture, and instruments are advanced through the steerable instrument channels. Manipulation of the instrument handles engages actuators positioned on the mount, which steer the distal ends of the cannulas through the action of pull cables. The distal ends of the instruments may thus be steered within the body by the distal ends of the steerable cannulas.
