Acetabular cup guide plate and manufacturing method thereof

Abstract

The invention relates to an acetabular cup guide plate and a manufacturing method thereof, relating to the technical field of medical equipment and solving the problems of key parameters such as the abduction angle, the anteversion angle and the rotation center of the acetabular cup when the acetabular cup is placed in the hip arthroplasty, and is helpful to improve the initial stability of the hip prosthesis after implantation and reduce the occurrence of the hip prosthesis dislocation. The main technical scheme of the acetabular cup guide plate is that a sticking surface; a plurality of positioning holes uniformly fixed on the sticking surface; a first hollow guide column connected with the sticking surface through three connecting rods, and comprising a proximal end of the first hollowguide column and a distal end of the first hollow guide column. When an acetabular cup guide plate is used in the acetabular fossa, the proximal end of the first hollow guide column does not exceed the acetabular fossa, and the distal end of the first hollow guide column is located at the rotational center of the acetabular fossa. The invention is mainly used for guiding the acetabular cup when the acetabular cup is implanted in the acetabular fossa.

AI Technical Summary

Benefits of technology

This patented technology helps create better bone for replacing damaged parts during orthopedic surgeries such as total knees or shoulder replacements. By aligning these guided columns along specific areas on both sides of the foot's heel where there are no teeth (the gums) between them), this allows precise placement without causing any damage from drilling holes into those regions. Additionally, when inserting screw implants, they help prevent their displacement due to gravity forces caused by weight bearing against other components like rods attached thereto. Overall, this method improves stability and reduces complications associated with existing methods used for hip replacement procedures.

Problems solved by technology

This patents describes various technical problem addressed in this patented text relating to orthopedic diseases caused by osteonecrosis due to improper procedures performed before replacing damaged teeth called primary implants. These issues include poor fit rates, reduced mobility, increased risks associated with revision operations, potential negative effects like pain relief medications, and difficulty determining optimal alignment of these prosthetic components. Current techniques involve measuring the orientation of the head relative to the body axis through X ray fluorescence analysis, but they lack accuracy.
