Problems solved by technology

[0004] After the existing hip joint prosthesis is implanted in the human body, the hip joint prosthesis moves between the angle formed by a cylindrical femoral neck and the edge of the acetabulum. In actual use, the femoral neck is prone to breakage, and the hip joint is easy to loosen , the femoral stem inserted into the bone is also prone to detachment

Abstract

The invention provides a novel titanium alloy joint stent coated with calcium phosphate bioactive ceramics. The stent comprising a joint handle, a metal ball head and a polyethylene mortar, wherein the metal ball head is connected with one end of the joint handle, and the metal ball head and the polyethylene mortar form a joint friction pair. The invention provides a novel titanium alloy joint support coated with calcium phosphate bioactive ceramic, which has good biocompatibility, long service life and convenient maintenance.

Description

technical field [0001] The invention relates to the field of medical technology, in particular to a novel titanium alloy joint support coated with calcium phosphate bioactive ceramics. Background technique [0002] The hip joint is composed of the femoral head and the acetabulum, which is a ball and socket joint. Only the lunate surface of the acetabulum is covered with articular cartilage, and the acetabular fossa is filled with fat, also known as the Haversian gland, which can be squeezed out or inhaled with the increase or decrease of intra-articular pressure to maintain the balance of intra-articular pressure. [0003] The hip joint is a multi-axial joint capable of flexion, extension, extension, rotation and circular motion. However, since the femoral head is deeply embedded in the acetabulum, and the acetabulum is deepened by the glenoid rim, which surrounds nearly 2 / 3 of the femoral head, the area difference between the joint head and the glenoid socket is very small...
