However, when the existing artificial bone particles are implanted into the defect site, the contact between the artificial bone particles and the host bone is not stable, especially the artificial bone particles are loose and unstable after being washed by blood, so that the artificial bone material in the defect site low stability, which affects the effect of artificial bone implants

[0107] The present disclosure also relates to a preparation method of artificial bone particles. The artificial bone particle 10 mentioned above can be obtained by the following method for preparing the artificial bone particle. It should be noted that the method for preparing artificial bone particles involved in the present disclosure can also prepare artificial bone particles with other structures. For example, structures such as twister, twister king, cube, cross or quadruped. The preparation method of artificial bone particles involved in the present disclosure can save raw materials and obtain artificial bone particles 10 with higher integrity. A detailed description will be given below in conjunction with the accompanying drawings.
[0108] Figure 14 is a flow chart showing the preparation method of the artificial bone particle 10 involved in the example of the present disclosure. Figure 15 is a flowchart showing a sintering treatment method of the artificial bone...

Abstract
The present disclosure relates to an artificial bone material for repairing bone defects, which is characterized in that it includes a plurality of artificial bone particles, and the plurality of artificial bone particles are stacked with each other to form an artificial bone material with a porosity of 60% to 90%, the artificial bone particles It includes a main body and a plurality of support columns formed on the main body. The main body is elongated and has an upper surface and a lower surface oppositely arranged. The main body has a through hole that runs through between the upper surface and the lower surface; the plurality of support columns The support column is arranged around the main body along the length direction of the main body part, and protrudes from the main body part along the length direction. According to the present disclosure, the stability of the artificial aggregate at the defect site can be improved.
Description
technical field [0001] The present disclosure generally relates to the field of clinical bone repair, and in particular to an artificial bone material for repairing bone defects and a preparation method of artificial bone particles. Background technique [0002] Bone defect is one of the common clinical diseases, such as trauma, inflammation, bone disease, surgery and other factors can cause bone tissue defect. At present, there are many methods for treating bone defects, such as autologous bone transplantation and allogeneic bone transplantation. Although autologous bone grafting is the gold standard for clinical bone defect repair, its bone supply is limited, shaping is difficult, and it cannot meet the repair requirements of large-scale specific shapes. Although allogeneic bone can solve the problem of limited bone source, it is prone to absorption deformation and strong antigenicity after implantation, which affects the therapeutic effect. [0003] In order to solve th...
