摘要：
A system for performing multi-tool minimally invasive medical procedures through a single instrument port in a body cavity includes a pair of steerable tool cannulas extending from a rigid tube that is supported by an operating room fixture. The rigid tube is extendable through an incision to position distal ends of the rigid tube and tool cannulas within a body cavity. Each tool cannula has a lumen for receiving a corresponding surgical instrument so that an end effector of the each instrument may be used within the body cavity. Control devices are operatively associated with each tool cannula and include ports for receiving the surgical instruments. User manipulation of the handles of the surgical instruments results in steering of the tool cannulas, and thus the surgical instruments, within the body cavity.
