The invention provides a positioning measuring device used for hip replacement
surgery and a measuring method. Through the using of a high-precision sensor and a high-performance
microprocessor to measure, the problems of manual error and
body position error of rulers can be solved; and the measuring device can be installed and fixed on the anterior superior iliac spines of the hip
pelvis of a patient with corresponding supporting tools to carry out measuring with the moving of the
pelvis, and the patient is the measured target, so that the influences of patient
standing positions on data canbe reduced. Through the measuring device and measuring method,
surgery can be high in flexibility, for the specific conditions of the patient, surgical programs can be planned in advanced, so that suitable supine and lateral positions can be selected; and the data can be measured in real time during operation, through two-way data comparison and
verification, better clinical curative effects can be achieved, and the probability of reoperation can be reduced. Based on a three-dimensional motion
data model, the position plane of a human
coronal plane can be accurately obtained according to three-dimensional motion data, so that the
processing of angles can be more accurate.
