Boston University School of Medicine: surgery technical training
Don’t miss to take a look at this website. There are few videos with orientation to the OR, scrubbing, sharp safety in OR, and some others interesting things.
I personally like the section about Basic Knot Tying & Suturing-A series of pages with both still and streaming video demonstrations of basic knot tying (two-handed tie, one-handed tie, instrument tie) and basic suturing techniques (simple interrupted, vertical mattress, simple running).
So, if you have time and wanna learn more about OR and some surgery techniques, go ahead and give it a try.
