Yes. There are definitely PAs in surgery. They practice under the licensure of the surgeon (physician), but they can sometimes do a lot of stuff under those auspices. They are not surgeons, and they are still PAs, but they work in the operating room and they do more than most surgical techs. Talk with a nearby PA program to see if they can put you in touch with a PA who works in this specialty, and s/he can tell you more specifics/limitations. Good luck.
