AI Technical Summary

⚠Technical Problem

Existing artificial acetabular cups have excessively thick solid metal parts, making it difficult to effectively transmit force to the human bone, thus affecting bone growth. Furthermore, they do not fit well with the human bone, making it difficult to promote bone growth.

⚗Method used

An artificial acetabular cup is designed with a solid inner dome and a porous outer dome. The inner layer is thinner than the outer layer. It is manufactured using 3D printing technology, and the outer surface is designed with spike structures to optimize the structure of orthopedic implants.

🎯Benefits of technology

It reduces production costs and weight, improves force transmission efficiency, promotes bone growth, enhances frictional fit with human bones, and has better adaptability.

Abstract

An artificial acetabular cup (100) and a method for manufacturing the same are provided. The artificial acetabular cup (100) has an annular seat (101) and a dome (102) extending from the annular seat. The dome (102) has an inner layer (1021) and an outer layer (1022) covering the inner layer. At least a portion of the inner layer (1021) of the dome (102) is a solid layer. At least a portion of the outer layer (1022) of the dome (102) is a porous structure layer. The thickness of the inner layer (1021) is less than the thickness of the porous structure layer of the outer layer (1022). The artificial acetabular cup (100) of this application has lower production costs and better performance.
