Abstract

The invention discloses a biological ceramic artificial joint spherical surface cyclic polishing machine. A first through hole is formed in a polished main body. A conveying screw is arranged in the first through hole in a penetrating manner. A circular arc-shaped first conveying groove is formed in the polished main body. Second conveying grooves are formed by two opposite side walls of the polished main body and end covers respectively. The top ends of the second conveying grooves communicate with the first conveying groove, and the bottom ends of the second conveying grooves communicate with the first through hole. Coils are located inside the polished main body. A magneto-rheological polishing liquid is located in the first conveying groove, the second conveying grooves and the first through hole. The biological ceramic artificial joint spherical surface cyclic polishing machine has the advantages that the conveying screw arranged in the first through hole in a penetrating manner plays a pushing part; cyclic polishing is conducted on a polished body placed in the first through hole in a closed cyclic channel; while the magneto-rheological polishing liquid is utilized for polishing; the magneto-rheological polishing liquid is in a liquid state form if not under the action of a magnetic field, and the closed cyclic channel wall can be covered completely by the magneto-rheological polishing liquid; and the magneto-rheological polishing liquid is transformed into a solid state form, numerous magneto-rheological brushes are formed, and omni-directional polishing is conductedon the periphery of the rotating polished body.

Description

technical field [0001] The invention relates to a bioceramic artificial joint spherical circular polishing machine. Background technique [0002] Joint lesions caused by human diseases or joint damage caused by accidents destroy the normal function of human joints and bring great inconvenience to the life and work of patients. According to statistics, about 10% of the world's population is using artificial hip joints to replace natural hip joints. The human hip joint is a spherical joint consisting of a spherical femoral head and a bowl-shaped acetabulum. Its alternative materials should have the properties of light weight, high strength, good biocompatibility, strong corrosion resistance, low fatigue caused by repeated stress, and wear resistance. The materials used for joint replacement implants are mainly metals, ceramics, polymers and composite materials. Ceramics are widely used due to their biological inertness, extreme stability in the human body, high hardness, an...
