I'm sorry I can't be of much help in med mal. Surgeon nicked my nerve when doing CTR and that has been difficult to deal with, but you have had a complete cut. There must be attorneys somewhere that would take the case.
This is something I would consider as a reportable incident to your state medical licensing board. In my state, there is supposed to be a list, one can access, of medical mistakes, where they occurred and what doctor made them. If I were you, I'd look into that route as far as reporting the surgeon to the American Medical Association and your state's licensing board.
But again, I'm sorry not to be of more help in the med mal end of things. What happened to you should not have happened. It is so frustrating, in order to get the surgery in the first place, you have to sign a paper that basically signs your life away.
After I had had a second surgery to try to correct my problem, I called the first surgeon to tell him that he had done something wrong, even though he denied it. The second surgeon confirmed the nick. The original surgeon's response was to say that that is why the patient signs a release form.
