摘要：
The present invention has a simple structure which is convenient in preparation and easy to use. Moreover, in combination with three-dimensional preoperative analysis and rapid molding technology, the present invention has a high customized precision and clinical applicability, and is cost-effective. Based on the three-dimensional preoperative analysis and 3d printing model, the problems of high technical difficulty and cost of the customized accurate implantation of acetabular cup prosthesis in the total hip arthroplasty can be effectively solved, so that the learning curve of operator can be shortened. The present invention can realize the customized accurate implantation of acetabular cup prosthesis without fitting the positioning guiding module with the articular surface area, so that the assisted positioning and assisted reaming depth determination are realized without removing the guiding module when the acetabulum is being reamed, thus the accuracy of the assisted positioning can be guaranteed.
