Injection simulation system and method

摘要

Provided is an injection simulation system and method. The system includes a syringe comprising an injection needle, a haptic unit which measures an insertion angle and insertion depth of the injection needle, and which comprises a motor unit that is driven by a haptic force corresponding to the measured insertion angle and insertion depth. The system also includes a control unit which calculates the haptic force corresponding to the insertion angle and the insertion depth, and transmits the calculated haptic force to the motor unit of the haptic unit.

1. An injection simulation system providing a haptic interface, comprising:
a syringe comprising an injection needle; a haptic unit comprising an internal structure configured to rotate corresponding to the insertion angle of the injection needle and comprising a motor unit, the haptic unit configured to measure the insertion angle and the insertion depth of the injection needle using the rotation of the internal structure, and the motor unit configured to be driven by a haptic force corresponding to the measured insertion angle and insertion depth; and a control unit configured to calculate the haptic force corresponding to the insertion angle and the insertion depth and to transmit the calculated haptic force to the motor unit of the haptic unit, wherein the injection hole comprises
a first rotating unit directly connected to a shaft of the motor unit and configured to transmit the haptic force; anda second rotating unit the height of which is controllable, wherein the injection needle is inserted between the first rotating unit and the second rotating unit; the injection needle comprises flat-shaped thin panel which increase an area of contact with the first rotating unit and the second rotating unit; and the first rotating unit and the second rotating unit are coated with urethane to increase friction with the injection needle.
