Abstract：
The invention relates to a total knee replacement pressure balance measuring system, which comprises a pressure acquiring device and a signal receiving and displaying device. The shape and dimension of the pressure acquiring device are the same as those of a tibia gasket in artificial knee prosthesis, and the pressure acquiring device is arranged at the knee joint of a patient during the operation so as to acquire a pressure signal and transmit the pressure signal to the signal receiving and displaying device. The signal receiving and displaying device performs force processing on the received pressure signal and displays the pressure distribution condition in a form of a three-dimensional pressure diagram so as to provide the stress condition at the tibia gasket of the artificial knee joint for a doctor in real time. The pressure acquiring device is arranged at the knee joint of the patient during the operation so as to acquire the pressure signal and is taken out after the pressure is balanced, and a proper tibia gasket is put at the knee joint of the patient. The total knee replacement pressure balance measuring system can be widely applied to the total knee replacement.
