A surgical system includes a robot main body, a slave controller, a display device that displays an endoscopic image, and an manipulation input device. The robot main body includes an entry guide having a plurality of guide bores, an entry guide support device that supports the entry guide, an instrument manipulator that has a surgical instrument provided at a distal end and is inserted into the entry guide, and an endoscope manipulator that has an endoscopic camera provided at a distal end and is inserted into the entry guide. The slave controller operates the robot main body such that the surgical instrument advances from an exit of the entry guide after the endoscopic camera advances from the exit of the entry guide and starts capturing in response to a body cavity insertion command received by the manipulation input device.
