[0002] Bone defects, bone necrosis, fractures, etc. caused by trauma, inflammation, tumors, etc. cause great pain and inconvenience to patients. Bone tissue has a regenerative function, but it can only occur when the defect area is small. Autologous bone transplantation is convenient and simple to obtain, and will not cause rejection reactions, but after all, the source is limited, and patients have to experience secondary pain. Allogeneic bone has a wide range of sources, but there will be problems such as immune rejection. Therefore, the research on bone tissue regeneration and repair materials is an important topic of concern in the biomedical field. Bone repair materials mainly include three categories: inorganic non-metallic materials, polymer materials and metal materials. At present, bone induction filling materials have also appeared, and filling plays a key role in bone regeneration. However, in the practical operation process, the filling material needs to be prepared and the material is prepared into a mud state for use. It is prepared by ordinary small-scale stirring, but it is easy to have insufficient stirring, which leads to uneven distribution of the components of the prepared material, which has an adverse effect on its induction regeneration effect.
