Problems solved by technology

Many patients have long-term loosening and central dislocation due to excessive bone loss, which affects the survival rate of the metal outer cup; and if the patient needs revision due to bone resorption, the standard metal outer cup can no longer meet the matching requirements. Require

Abstract

The embodiment of the invention provides a three-dimensional metal outer cup and a manufacturing method. The three-dimensional metal outer cup comprises a cup body and an outer casing sleeving the cupbody; the cup body is fixedly connected with the outer casing; the cup body is of a bowl-shaped structure, the inwards-sunken face of the cup body fits the shape of an outer cup lining, and the face,away from the outer cup lining, of the cup body fits the outer casing; and the outer casing is of a bowl-shaped structure, the inwards-concave face of the outer casing fits the cup body, and the face, away from the cup body, of the outer casing fits the shape of the acetabulum side of a patient. Through the three-dimensional printed outer casing, the outer casing is matched with the acetabulum side of the patient, so that excision rate of more high-quality bone is reduced. The central dislocation caused by long-term looseness caused by excessive bone loss of the patient is prevented, the survival rate of the metal outer cup is improved, and the matching degree is improved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a three-dimensional metal outer cup and a manufacturing method. Background technique [0002] In recent years, with the acceleration of the population aging process, the number of hip joint patients has continued to increase, with an annual growth rate of 20%. Artificial hip replacement has become an effective treatment for many end-stage hip joint patients. Through hip replacement, It can solve patients' pain, difficulty in movement and various complications, such as deep vein thrombosis, pneumonitis and decubitus and other high-risk diseases, and restore the functions of the patient's hip joints, effectively improving the quality of life. When the hip joint creates a hip, the cartilage is no longer smooth, the synovial bursa becomes inflamed and shrinks, and the joint can no longer function as well as it normally does. Hip metal cup replacement can relieve pain, improv...
