Embodiment 1
[0033] A multi-scale surface structure implant, which includes a micron-scale microstructure array, and the surface of the implant is covered with nanoscale holes with a diameter of 200nm, the microstructure array is a micro-pyramid array, a micro-barb array or a micro-groove any of the arrays.
[0034] Wherein, the micro-pyramid array is several pyramids arranged equidistantly, and the longitudinal section of the pyramid is a triangle I; the base length b1 of the triangle I is 30 μm, the height h1 is 20 μm, and the distance s1 between two adjacent triangles I is 80 μm, the size of the pyramid is adapted to the placement of the implant, see figure 1 .
[0035] The micro-barb array is a number of barbs arranged equidistantly. The longitudinal section of the barb is a triangle II and a rectangle connected up and down. h2 is 100 μm, the distance s2 between two adjacent rectangles is 80 μm, the size of the barb is adapted to the implantation position of the implant, see figure...
