The invention relates to an anti-
thrombosis and anti-infection
titanium alloy implantation instrument with an alveolate porous structure and belongs to the technical field of
surface modification of
metal materials. According to the method, a traditional
femtosecond laser shaping mode is replaced with a
femtosecond laser dual-
pulse mode, correspondingly a local instantaneous electronic state of amaterial is adjusted and controlled, and different micro-nano composite structures can be prepared. Through dynamic regulation and control of electrons, the unique alveolate porous structure is finally processed. According to the structure, the static
contact angle between the structure and fresh rabbit blood is 143.4 degrees + / - 2.6 degrees, and the
rolling angle is 8.5 degrees + / - 2 degrees. Because a fluorinated material has low
surface energy, certain
frictional resistance and excellent bactericidal and
antithrombotic capability, by conducting fluorination treatment on a
NiTi alloy surfaceof the alveolate porous structure, a super blood dispersing surface is obtained, wherein the static
contact angle between the super blood dispersing surface and the fresh rabbit blood is 167.3 degrees + / -3.2 degrees, and the
rolling angle of the super blood dispersing surface is 1.6 degrees + / - 0.3 degree; meanwhile, the obtained surface also has excellent antibacterial performance. The method isapplicable to the surfaces of
titanium alloy materials different in size and shape.
