Abstract

The invention discloses a medical titanium alloy screw airbag magnetorheological brush polisher which comprises a lathe, a polishing solution containing magnetorheological fluid, a magnetic polishing assembly fixed on a tool post carriage of the lathe and a pump body which sprays the polishing solution on the magnetic polishing assembly; the magnetic polishing assembly comprises a clamp holder fixed on the tool post carriage of the lathe, a magnetic field emitter arranged on the clamp holder, an airbag assembly arranged on the magnetic field emitter and a guide magnetic brush plate which is movably arranged on the airbag assembly, an air pump is further fixed on the tool post carriage of the lathe, and a breather pipe which is communicated with the magnetic filed emitter and the airbag assembly and penetrates through the clamp holder is connected to the air pump. The medical titanium alloy screw airbag magnetorheological brush polisher has the advantages that by means of the airbag assembly and the guide magnetic brush plate, pressure stress does not occur on the surface layer of a workpiece, damage does not exist, the hardness of the magnetorheological brush is controlled by controlling the magnetic field intensity, and a large area of magnetorheological brush is arranged on the exterior of an airbag to grind the workpiece, so that the workpiece is ground in multiple directions.

Description

technical field [0001] The invention relates to a medical titanium alloy screw airbag magneto-rheological brush polishing machine. Background technique [0002] At present, medical intramedullary nails and bone screws are mostly made of titanium alloy materials. The main problem of titanium alloy implant materials is corrosion. On the one hand, corrosion causes corrosion products to enter the human body, causing serious physiological hazards, such as tissue poisoning, cell Distortion, etc.; on the other hand, cause failure behaviors such as loosening and early fracture of the implanted prosthesis. The corrosion resistance of titanium alloy decreases with the increase of its surface roughness, among which smooth surface and microscopically rough surface have good corrosion resistance and low ion release rate. Therefore, it is particularly necessary to carry out proper surface finishing treatment on medical titanium alloy implants. Contents of the invention [0003] The ob...
