Abstract

The present application provides a method, device and system for measuring the angle of an acetabular cup prosthesis. The method includes: obtaining CT data of the pelvis after hip replacement surgery; performing three-dimensional reconstruction on the CT data to obtain a three-dimensional model of the pelvis and a three-dimensional model of the acetabular cup prosthesis; The model measures the anteversion and abduction angles of the acetabular cup prosthesis. This method obtains the three-dimensional model of the pelvis and the three-dimensional model of the acetabular cup prosthesis through three-dimensional reconstruction of CT data, so as to measure the anteversion angle and abduction of the acetabular cup prosthesis according to the three-dimensional model of the pelvis and the three-dimensional model of the acetabular cup prosthesis Angle, because the anteversion angle and abduction angle of the acetabular cup prosthesis are three-dimensional angles, compared with the existing technology to measure the anteversion angle and abduction angle of the acetabular cup prosthesis by two-dimensional X-ray film, the error is greatly reduced The method solves the problem of large measurement error in the measurement method of the acetabular cup angle in the prior art.

Description

technical field [0001] The present application relates to the field of medical technology, in particular, to a method, device, computer-readable storage medium, processor and measurement system for measuring the angle of an acetabular cup prosthesis. Background technique [0002] With the continuous development of medical technology, hip replacement surgery has made great progress in many aspects, and the condition of patients after surgery has also received extensive attention. The acetabular cup angle greatly affects the stability of the hip joint after surgery, the life of the prosthesis, and the risk of postoperative complications. In traditional total hip arthroplasty, doctors design the angle of acetabular cup implantation based on experience and intraoperative auxiliary tools, so evaluating the accuracy of postoperative acetabular cup placement and measuring the actual angle of the acetabular cup appears to be very meaningful. [0003] Even if doctors use a navigati...
