Description

Technical Field

[0001] The utility model relates to the technical field of bone repair material production, in particular to a pulverizing device for producing micro-particle bone repair material. Background Art

[0002] Bones are important tissues and organs of the human body. Bone defects are very common in clinical practice. Bone defects hinder the crawling of bone cells, causing bone nonunion and affecting bone healing. The most effective method to repair bone defects is the transplantation of bone repair materials. The original bone repair materials were autologous bones, allogeneic bones and animal bones. These materials are not only very limited in source, but also cause the pain of secondary surgery for autologous bones and allogeneic bones; allogeneic bones and animal bones are prone to immune rejection reactions. Therefore, it is of great significance to develop artificial bone repair materials with a wide range of sources. As a bone repair material, in addition to having excellent mechanical properties, it is also required to have: 1. Good hydrophilicity to facilitate cell adhesion, proliferation and differentiation; 2. Good biocompatibility, no adverse reactions to the body. Polyphenylene sulfide (PPS) is a special engineering plastic with excellent comprehensive performance. It has the characteristics of excellent high temperature resistance, corrosion resistance, radiation resistance, flame retardancy, balanced mechanical properties, excellent dimensional stability and excellent electrical properties. Polyphenylene sulfide and its modified or composite materials have been successfully applied in the fields of electronics, aerospace, automobile transportation, etc., but as a high-performance polymer material, polyphenylene sulfide is rarely used in the field of medical materials. In the production process of composite polyphenylene sulfide, glass fiber, carbon fiber, calcium carbonate or other inorganic fillers are generally added to polyphenylene sulfide by physical blending. Since nanopowders have significant advantages over conventional powders in improving the comprehensive properties of polymers (such as hydrophilic properties, mechanical properties, etc.), the preparation of various composite materials with nanomaterials is also one of the hot spots in the current research field of materials science.
