Embodiment Construction
[0030] The preparation method of the PEEK composite material artificial hip joint suitable for 3D printing of the present invention comprises the following steps:
[0031] (1) Three-dimensional modeling design of artificial hip joint
[0032] Use CT scanning technology to obtain the shape data of the patient's hip joint, including the femur and acetabulum, and use computer CAD 3D reconstruction technology to construct a 3D model of the artificial hip joint based on the scan data. Then, according to the effect of computer virtual hip joint replacement, the three-dimensional shape of the artificial hip joint is corrected; then the contact surface between the artificial hip joint and the human bone is designed into a network slot structure or a honeycomb hole structure, and the artificial hip joint The contact surface between the joint and human bone includes the contact surface between the artificial acetabulum and the human hip bone and the contact surface between the artificia...

Abstract
The invention provides a method for preparing a PEEK composite material artificial hip joint suitable for 3D printing, which uses digital technology to design the three-dimensional shape of the artificial hip joint, and designs the contact surface of the artificial hip joint and human bone into a mesh like grooved structure or honeycomb hole structure, and then use CaCO 3 The PEEK composite material of the whiskers is used as the 3D printing material of the artificial hip joint. According to the designed modeling data, the artificial hip joint is printed with a special 3D printer, and then the contact surface between the artificial hip joint and the human bone is treated and the active bone paste is applied. , thereby obtaining an artificial hip joint with superior performance. This method can be used to quickly prepare personalized artificial hip joints, and the prepared artificial hip joints have good mechanical properties and wear resistance, and the elastic modulus is similar to that of human bones, and also have good biological activity and osteoinductivity, and can be Guide bone regeneration, so that the interface between artificial hip joint and human bone can heal well.
Description
technical field [0001] The invention relates to a preparation method of an artificial hip joint, in particular to a preparation method of a PEEK composite material artificial hip joint suitable for 3D printing, and belongs to the technical field of orthopedic surgery medical material preparation. Background technique [0002] In recent years, with the development of economy and science and technology, the development level of tissue engineering and regenerative medicine has been greatly improved, thus providing a new option for the repair of bone defects, applying bone tissue engineering technology to large areas of bone defects Treatment can overcome the shortcomings of autologous bone graft and allogeneic bone graft. Bone tissue engineering requires artificial bone to be composed of biomaterials with good osteoconductivity and osteoinductivity, and good biocompatibility and biodegradability. [0003] With the advent of an aging society, femoral head necrosis and femoral n...
