The position of opening portion 13 is reliably within the body of the patient. A shaft 14 is arranged along the interior of the trocar, along an edge of the opening portion 13. Several bearings 15 are fixed to the inter wall of the pipe portion 11, with the shaft 14 being rotatably mounted in the bearings 15. The end portion of the shaft 14 extends to the exterior of the trocar, outside the body of the patient. A selection lever 16 is provided at the outer end portion of the shaft 14. The selection lever 16 can be changed over between a stored position and a deployed position, and can be fixed in each of these positions. A camera 17 is rigidly and integrally attached to the shaft 14 at a position that corresponds to the opening portion 13. A cable 18 is connected to the camera 17, extends through the interior of the trocar 1, and is connected to an external image processing device 6.
