None of the above: I’m a surgical tech, my role is to get the instruments, supplies, and equipment needed for a surgery; establish sterile fields and get those instruments etc on them in a sterile way; facilitate the actual surgery by making sure the surgeon never has idle hands (we have to know the surgeries well enough to anticipate what instrument the surgeon will want in each step), and get the room turned over for the next case.
It’s a cool job, but the pay’s kinda shit, so I don’t recommend it as anything other than a stepping stone to something like nursing, which is what I’m currently working toward.
