Problems solved by technology

[0004] However, the real acetabular cup coverage is a three-dimensional concept, and the use of two-dimensional imaging data will lose some information in three-dimensional space, and different perspective angles often lead to a deviation between the calculated acetabular cup coverage and the real value
In addition, due to the use of X-ray imaging during the operation, the radiation generated will cause a certain degree of harm to the patient's body.

Abstract

The invention relates to the technical field of medical instruments, in particular to a method, device and equipment for calculating the coverage rate of a three-dimensional acetabular cup prosthesis and a storage medium. According to the method, a collision detection algorithm based on point primitives is introduced into calculation of the three-dimensional acetabular cup coverage rate, so that a doctor can obtain a relatively real acetabular cup coverage rate through a planned operation scheme and a patient CT image before an operation, and the operation scheme planned before the operation can be better evaluated. In the operation, a doctor can adjust the position of the acetabular cup in the acetabular fossa and the forward and abduction angle of placement or replace the model of the acetabular cup, so that the coverage rate of the three-dimensional acetabular cup reaches 70% of the lowest coverage rate which is internationally recognized at present, and the possibility that the acetabular cup falls off after the operation is greatly reduced. In addition, experiments show that compared with the conventional image-based two-dimensional acetabular cup coverage rate, the method can more accurately reflect the implantation condition and stability of the current acetabular cup.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a method, device, equipment and storage medium for calculating the coverage ratio of a three-dimensional acetabular cup prosthesis. Background technique [0002] In recent years, artificial total hip replacement surgery is an effective treatment for hip joint diseases and has been widely carried out at home and abroad. However, the follow-up found that the service life of artificial joints was affected by postoperative complications (loosening), among which, the loosening of the acetabular cup side prosthesis was particularly common. There is a certain correlation between the loosening of the acetabular prosthesis and the bony coverage of the acetabular cup immediately after surgery. The acetabular prosthesis coverage is used to test the coverage of the acetabular prosthesis. When the acetabular prosthesis coverage is greater than 75% Only in this way can the postoperati...
