摘要：
Systems and methods for performing a surgical procedure within a body cavity. The systems include a cannula having a tubular body with ports located at first and second ends thereof, wherein the second end is configured to be inserted into the cavity. The systems further include one or more tools configured to be inserted into the cannula through the ports on the first end, extend through the body of the cannula, and protrude from the ports on the second end. The tools each include a shaft with a working element on a distal end of the shaft, at least portions of which are capable of articulation relative to the shaft, rotation relative to the cannula, and are configured to perform tasks in the cavity. The working element may be produced with an additive manufacturing technique.
