Abstract：
The invention discloses a method and a system for acquiring posture of an acetabular bone and a femoral head in novel hip arthroplasty. The method comprises the following steps of: setting pressure sensors and/or touch sensors and an image sensor on a femoral head false test mould to form a sensor array; acquiring the contact and stress condition and position information of the femoral head false test mould and acetabular bone by the sensor array, and sending a signal; and receiving the signal by a receiving end, and displaying the received signal on a display module, so as to acquire the analogue postures of the acetabular bone and the femoral head. The system comprises the sensor array, a necessary external circuit and a signal receiving and displaying device for receiving and displaying the signal emitted by the external circuit. According to the invention, the existing posture of the femoral head false body can be accurately simulated during the hip arthroplasty, so that a doctor can intuitively see the position and movement status of the femoral head false body during the hip arthroplasty, and further, the success rate and the surgical treatment of the hip arthroplasty can be greatly improved.
