Patterned silver coating antibacterial implantation device based on subtractive thinking and preparation method thereof

The invention discloses a patterned silver coating antibacterial implantation device based on subtractive thinking and a preparation method thereof. The antibacterial implantation instrument is prepared by using a combined process of vacuum magnetron sputtering silver plating, electrochemical silver plating, chemical deplating, mechanical deplating and the like in sequence, and the specific preparation process is as follows: performing vacuum ion cleaning on a medical titanium/titanium alloy base material to remove impurities and an oxide layer on the surface of the base material; performing vacuum magnetron sputtering silver plating and electrochemical silver plating on the medical titanium/titanium alloy base material to obtain the silver coating antibacterial implantation instrument. Using a protective sleeve to physically shield the silver coating antibacterial implantation instrument, and placing the silver coating antibacterial implantation instrument in a deplating solution to carry out primary chemica
