| Zusammenfassung: | A trocar for inserting a surgical instrument in a body may include: a pipe including an outer cylinder relatively slidable in an axial direction, and an inner cylinder; a head located on a proximal end of the pipe; a camera that is journaled in a distal end notch of the pipe inner cylinder so as to be turnable between a deployment state in which the camera rotates to the outside of the pipe and a storage state in which the camera is stored inside the pipe; and a coil spring biasing the camera to the deployment state. |
