Problems solved by technology

[0003] It is known that the artificial joint is a friction pair composed of metal, polymer material or ceramic material instead of the friction pair composed of articular bone (including articular surface and cartilage), and the artificial joint also lacks the secretion and storage of synovial fluid in human joints. Joint capsule
For this reason, a lot of research has been done in the existing design, and it is expected to improve the lubrication condition of the artificial joint by changing the design and material of the joint pair, but it has not been significantly improved, and a large number of related problems still exist
At the same time, the firmness of the growth of the hip prosthesis is still an ongoing problem

Embodiment Construction

[0016] like figure 1 As shown: the bionic hip joint includes a hip joint handle 1 and a bionic joint capsule 2; the lower end of the hip joint handle 1 is connected with a titanium alloy ball head 4 through wedge-shaped insertion, and the titanium alloy ball head 4 is connected with a polyethylene socket 3 Matching constitutes a joint friction pair; the bionic joint capsule 2 is a bowl-shaped capsule made of silicone, with a central hole on the top that is set and fixed with the hip joint handle 1, and the periphery of the bowl is glued to the top surface of the polyethylene socket 3. Combined with bonding and fixation, a joint cavity 6 is formed between the bionic joint capsule 2 and the hip joint handle 1, the titanium alloy ball head 4 and the polyethylene socket 3, and synovial fluid is stored in the joint cavity 6; the outer layer of the polyethylene socket 3 It is also matched with a titanium alloy socket 5, and three annular bosses 7 are attached to the surface of the t...

Abstract

The invention provides a hip joint prosthesis. The hip joint prosthesis comprises a hip joint handle and a bionic joint capsule, and a ball head is connected to the lower end of the hip joint handle and matched with a socket to form a joint friction matching pair; the bionic joint capsule is a bowl-type capsule, a center hole is formed in the top of the bionic joint capsule, hip joint handle is sleeved with the bionic joint capsule and fixedly connected with the bionic joint capsule, and the periphery of a bowl opening is attached to the top surface of the socket and fixedly connected with the top surface of the socket. According to the designed hip joint prosthesis, a plurality of grooves are additionally formed in the hip joint handle, so that mechanical properties are met well, the service life of the hip joint prosthesis is prolonged, the implantation comfort level of the hip joint prosthesis is improved, and stability and anti-rotation performance after the prosthesis is implanted are improved.

Description

technical field [0001] The invention relates to a hip joint prosthesis, which belongs to the medical and health field. Background technique [0002] In medical clinical treatment of various advanced diseases of the hip joint, such as femoral head necrosis, etc., the method of hip joint replacement surgery is generally used, and artificially manufactured hip joint prosthesis is implanted in the body to fix and support the human hip joint. The anatomical structure, and make it obtain normal mechanical properties to complete certain physiological functions, thereby achieving the purpose of relieving pain and improving function. [0003] It is known that the artificial joint is a friction pair composed of metal, polymer material or ceramic material instead of the friction pair composed of articular bone (including articular surface and cartilage), and the artificial joint also lacks the secretion and storage of synovial fluid in human joints. joint capsule. For this reason, a ...
