Surgeon here. This is the equivalent of using it to “remember” what utensils to place at a formal dinner setting. It generated the headlines they wanted but they basically wasted $4k of government money for a lark. It’s not like the surgery was impossible without it or the outcome improved. The scrub nurse was probably insulted having to wear something telling her how to do a job she’s done hundreds if not thousands of times.  Also…how do you sterilize an AVP? As in, sterilize it sufficiently for a surgery, pre and post op.
