Embodiment Construction

[0032] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and embodiments. The following examples are intended to illustrate the present invention, but not to limit the scope of the present invention.

[0033] like figure 1 - Figure 4 As shown, a polyetheretherketone artificial vertebral body according to a preferred embodiment of the present invention includes a vertebral body main body 1 and a support frame 2, and a bone graft space 11 is provided in the middle of the vertebral body main body 1 to implant bone into the vertebral body. In the main body 1, the problem of slow bone growth can be solved, the osseointegration performance of the prosthesis-bone interface can be improved, and the fusion rate and fusion speed of the prosthesis can be improved; the support frame 2 is embedded in the outer periphery of the vertebral body main body 1, and all the The periphery of the support frame 2...

Abstract

The invention relates to the technical field of artificial prostheses, and discloses a polyetheretherketone artificial vertebral body, comprising a vertebral body main body and a support frame, the vertebral body main body is made of polyetheretherketone, and the middle part of the vertebral body main body is made of polyetheretherketone. A bone graft space is provided, the support frame is embedded in the outer circumference of the vertebral body, and the outer circumference of the support frame is flush with the outer circumference of the vertebral body. The invention increases the osseointegration performance of the artificial vertebral body-bone interface, improves the fusion rate and fusion speed of the artificial vertebral body, and forms a stable whole with the main structure of the vertebral body through the embedded support frame, thereby improving the artificial vertebral body. The overall rigidity of the artificial vertebral body is improved, thereby improving the supporting efficiency of the overall structure of the artificial vertebral body, and can meet the supporting strength requirements of the artificial vertebral body.

Description

technical field [0001] The invention relates to the technical field of artificial prostheses, in particular to a polyetheretherketone artificial vertebral body. Background technique [0002] Large-segment bone defects of the spine caused by various diseases, such as primary malignant bone tumors of the spine and en bloc resection of oligometastatic lesions of spinal metastases, all require prosthetic reconstruction. At present, the main prostheses used include titanium cages, traditional mechanically processed artificial vertebral bodies, and 3D printed artificial vertebral bodies. Among them, the application of 3D printing artificial vertebral bodies is more and more extensive. 3D printing technology enables the prosthesis to conform to the bone defect, so that the reconstructed prosthesis has optimal mechanical conduction performance; in addition, the 3D printing porous structure bone contact interface realizes rapid osseointegration, making the reconstructed prosthesis f...
