Abstract:
1. A method of performing a minimally invasive medical procedure within a body cavity, comprising the steps of: providing an access system including a mount, a rigid tube having a distal end and first and second cannulas extending from the distal end, and first and second actuators fixed to the mount; forming a percutaneous incision; advancing a distal end of the rigid tube through the incision to position the distal ends of the rigid tube and the cannulas within the body cavity; attaching the mount to an operating room fixture, the mount maintaining the position of the rigid tube in the incision; introducing a first end effector of a first instrument into a port on the first actuator, and advancing the end effector through the first cannula and out the distal end of the first cannula; introducing a second end effector of a second instrument into a port on the second actuator, and advancing the end effector through the second cannula and out the distal end of the second cannula; manipulating the handles of the first and second instruments, the handles engaging the actuator to deflect distal portions of the cannulas, said deflection altering the orientation of the instruments within the body cavity; and performing a procedure in the body cavity using the end effectors.
