Abstract

The invention provides a method, a device and a system for measuring the angle of an acetabular cup prosthesis. The method comprises the following steps: acquiring CT data of a pelvis after a hip replacement operation; 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; and according to the three-dimensional model of the pelvis and the three-dimensional model of the acetabular cup prosthesis, measuring the front rake angle and the abduction angle of the acetabular cup prosthesis. According to the method, three-dimensional reconstruction is carried out through CT data to obtain a three-dimensional model of a pelvis and a three-dimensional model of an acetabular cup prosthesis, and therefore the front rake angle and the abduction angle of the acetabular cup prosthesis are measured according to the three-dimensional model of the pelvis and the three-dimensional model of the acetabular cup prosthesis. Compared with the prior art that the anteversion angle and abduction angle of the acetabular cup prosthesis are measured through a two-dimensional X-ray film, errors are greatly reduced, and the problem that in the prior art, an acetabular cup angle measuring method is large in measuring error is solved.

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, great progress has been made in many aspects of hip replacement surgery, and the condition of postoperative patients has also received extensive attention. The angle of the acetabular cup greatly affects the stability of the hip joint, the life of the prosthesis, and the risk of postoperative complications. In traditional total hip replacement, doctors design the angle of acetabular cup implantation based on experience and intraoperative auxiliary tools, so it is important to evaluate the accuracy of postoperative acetabular cup placement and measure the actual angle of acetabular cup. very meaningful. [0003] Even if the doctor uses the navi...
