[Problem] To provide a medical training simulation model having a display enabling training by a simulation model simulating the structure of an organism, and objective and visual recognition of the three-dimensional position of an inserted endoscope, a finger or the like in an organ or tissue. [Means for Solving the Problem] A teaching material model system having a teaching material model for clinical examination inside of an organism has a display screen creating device for creating the internal structure of an organism model formed of a nonmagnetic material by three-dimensional CG on a display screen, a specific signal transmitting device, and a sensor for detecting a signal from the specific signal transmitting device as constituting device, wherein the signal generated by the specific signal transmitting device is detected by the sensor, the signal detected by the sensor is transmitted to create a display screen by the display screen creating device, and the system is provided with a real time display device for displaying the positional situation of the sensor created on the display screen for the internal structure of a teaching material organism model displayed on the display screen by three-dimensional CG.
