The invention belongs to the technical field of bone fracture medical materials, and particularly relates to a biological activity glass material broken bone connector used for bone fracture surgery,and a use method of the biological activity glass material broken bone connector. The broken bone connector comprises a steel plate and bolts cooperated with the steel plate through anti-falling elements, wherein the surface of the steel plate is coated with a biological activity glass coating; the bottom of the nut of each blot is provided with a spacing bulge; and the steel plate is provided with assembling grooves adaptive to the anti-falling elements, and fixing holes adaptive to the bolts. The anti-falling elements are additionally arranged on a traditional broken bone connection device structure, a fastening connection way is adopted to realize fixing between a spacing inner ring plate and an anti-falling outer ring plate, a contact area between the bolts and the steel plate is enlarged, so that bolt connection is stable and firm, and an anti-falling effect is better. The biological activity glass composite material is applied to the broken bone connection device, and the biological activity of the biological activity glass composite material is used for performing the functions of accelerating cell multiplying and enhancing gene expression of osteoblasts and growth of bone tissues.
Description
technical field [0001] The invention relates to the technical field of fracture medical materials, in particular to a bioactive glass material fracture connector for fracture surgery and a method for using the same. Background technique [0002] Bioactive glass is a kind of material that can repair, replace and regenerate body tissues, and can form a bond between tissues and materials. Discovered by Hench in 1969, BAG is a silicate glass composed of basic components such as SiO2, Na2O, CaO and P2O5. The degradation products of bioactive glass can promote the production of growth factors, promote the reproduction of cells, enhance the gene expression of osteoblasts and the growth of bone tissue. It is the only artificial biomaterial that can bond with bone tissue and connect with soft tissue so far. [0003] Proximal humeral locking kits are often used in the surgery of proximal humeral fractures, and the humerus is fixed and connected with bone plate screws. In the process...
