Abstract：
The invention discloses an attitude acquisition method and system for acetabulum and femoral head in artificial hip joint replacement. Pressure sensors and/or touch sensors are arranged at concerned pressure point positions of hip joint replacement on femoral head prosthesis template, to form a sensor array; the sensor array acquires contact and stress conditions between the femoral head prosthesis template and acetabulum, and sends out signals; and a receiving terminal receives the signals, and displays on a display module, to acquire simulated attitudes of acetabulum and femoral head. The system comprises the sensor array, necessary peripheral circuits, and a signal receiving and display device for receiving and displaying signals sent from the peripheral circuits. The method and system provided by the invention can accurately simulate attitude of femoral head prosthesis in artificial hip joint replacement, so that a doctor can visually observe position and movement condition of femoral head prosthesis during operation process, to greatly improve success ratio and surgical effect of hip joint replacement.
