Abstract: A device for endoscopic simulation includes an endoscopic interface with a guiding tube for guiding an endoscope. The tube is mounted on bearings for free rotation and includes windows for allowing a contact between the endoscope and friction rollers for tracking axial displacement of the endoscope and for imposing a linear force feedback on the endoscope. One friction roller is connected to a motor for transmission of torque generated by the motor. Another friction roller is connected to an encoder for tracking its axial displacement. The device further includes an axial brake for blocking axial movement of the endoscope while allowing rotation of the endoscope. The axial brake includes two pairs of brake rollers placed around the endoscope. One pair of brake rollers is movable relatively to another pair for realizing the axial blocking.
