[0065] Preparation of porous Ti6A4V prosthesis
[0066] The porous titanium alloy stent used in the embodiment of the present invention is prepared by EBM (electron beam melting) rapid prototyping technology, including 3 kinds of specifications for different test and detection respectively: (1) a cylinder with a diameter of 10mm and a height of 5mm , used for cell experiments; (2) A cylinder with a diameter of 5 mm and a height of 6 mm, used for material characterization, in vitro mechanical testing, cell culture, implantation experiments, etc.; (3) EBM technology was used to prepare pictures with a diameter of 10 mm and a thickness of 1 mm Ti6A14V-like material was used for characterization. See Table 1 below.
[0067]
[0068] The prosthesis is designed based on CAD image software (CATIA and INCATUSA), with an internal pore diameter of 640 μm, and a pillar diameter of 400 μm, which is a cylinder with diamond-like lattice pores. After the design is completed, export the ...
Embodiment 1
[0069] Embodiment 1: Structure and parameter design of photofunctionalized instrument
[0070] See attached figure 1 , provides an example of the photofunctionalized irradiation device of the present invention, its parameters satisfy:
[0071] 1) The light source is composed of two groups of wave bands, one group is 365±20nm (365nm is the peak value, hereinafter referred to as the 365nm band), and the other group is 270±20nm (270nm is the peak value, hereinafter referred to as the 270nm band); the light source is an LED light source, which is small in size and convenient Compactly arranged, the ultraviolet wavelength emitted by the light source is usually dominated by a certain wavelength, supplemented by adjacent wavelengths, so only the peak value is used to describe the light source;
[0072] 2) When irradiating, the energy distribution at any position of the cavity: the irradiating energy in the 270nm band is greater than 2mw / cm 2 , 365nm band irradiation energy is great...
Embodiment 2
[0078] Embodiment 2: Using the optical functionalization instrument of the present invention to carry out optical functionalization treatment on titanium alloy materials and experimental detection of treated titanium alloy materials
[0079] 2.1 Experimental grouping and corresponding processing
[0080] The experiment was divided into 5 groups, namely GC (control group), GL, G270, G365 and GU. Among them, GC did not accept light treatment, and GL accepted 15 minutes of ultraviolet high-pressure mercury lamp irradiation; G270, G365 and GU groups were instrument treatment groups of the present invention, which were respectively 270nm, 365nm, 270nm and 365nm dual-wavelength irradiation, and the irradiation time was 15 minutes. minute.
[0081] GC (control group) treatment process: after 4 weeks in a laboratory environment (normal temperature, normal pressure, air environment), place it on a sterile operating table for 15 minutes (without irradiation), and keep it sealed for 24 ...
