The invention belongs to the field of medical apparatus, and more specifically relates to titanium silver alloy nanotube for surgery fixing apparatus and preparation method thereof. The titanium silver alloy nanotube for surgery fixing apparatus contains 1-5 wt. % of silver, and the balance being titanium; the caliber of the nanotube is between 20 and 100 nm, and the length of the tube is between 1 and 50 mu m. The preparation method is as follows: firstly synthesizing titanium silver alloy using fusion method in a high temperature forge, and then carrying out a two-step anodic oxidation treatment for titanium silver alloy, finally drying in a muffle furnace at 400-500 DEG C, and controlling the heating speed for 2-4 DEG C/min, and obtaining a silver titanium alloy nanotube. The titanium silver alloy nanotube of the present invention is like a surgery fixing fixed apparatus, and antibacterial property of surgery fixing apparatus is added, and the silver and titanium have abundant sources with low price, and the product is easy to be popularized.
