An anesthesia workstation includes a sliding track system attached to the front of the anesthesia workstation for the mounting of one or more displays. The counter mass is arranged such that the rest position is closer to the main handle than the center of gravity is to the main handle. The output shaft has a magnetized region. Stopping occlusion growth at the zone of the infusion ports prevents further growth distally to the aspirating port and protects the aspirating port from being blocked by the growth of occlusion.
