A system for simulating a surgery, the system comprising: a first haptic arm representative of an actual surgical tool; a first haptic mechanism in mechanical communication with the first haptic arm, wherein the haptic arm and haptic mechanism are configured to provide real time haptic force feedback to a user of the system during simulation of a surgery; a haptic control unit configured to signal to the first haptic mechanism a level of haptic force feedback; a first computer in electronic communication with the haptic control unit and comprising a software module having a physics-based model of a portion of the human body and configured to calculate the haptic force feedback to be provided by the first haptic arm and first haptic mechanism, wherein the calculated haptic force feedback corresponds to substantially the same forces exerted on the actual surgical tool when it interacts with the portion of the human body during live surgery; and a simulated microscope having a display (2.2), wherein the display (2.2) is configured to show, at the same time and while said system is simulating a surgery, a three-dimensional simulated image of the portion of the human body, a three-dimensional image showing a first simulated surgical tool corresponding to the actual surgical tool, a two-dimensional simulated view of the portion of the human body, and a two-dimensional view showing the first simulated surgical tool, based on the current orientation and position of the first haptic arm under the simulated microscope; wherein the two-dimensional view of the first simulated surgical tool is displayed in relation to the two-dimensional simulated view of the portion of the human body including relative orientation and/or position of the portion of the surgical tool to the portion of the human body; wherein based upon changes in orientation and movements of the haptic arm under the simulated microscope, the display (2.2) is configured to update in real time the relative position of the three-dimensional simulated image of the portion of the human body, the three-dimensional image showing the first simulated surgical tool, the two-dimensional simulated view of the portion of the human body, and the two-dimensional view showing the first simulated surgical tool; wherein the calculated haptic force feedback is based on detected interactions between the first simulated surgical tool and the portion of the human body in the display (2.2); wherein the first simulated surgical tool has a tip at one end of the tool; and wherein the two-dimensional view of the portion of the human body and the two-dimensional view showing the first surgical tool are displayed within a window on the display (2.2), and wherein the entire window is displayed over at least a portion of the three-dimensional image of the portion of the human body. a first haptic arm representative of an actual surgical tool;
