Plastic and Reconstructive Surgery is your game, my friend! Lots of procedures, many of the patients are long-term (ie, repeat aesthetic patients, trauma, burn, skin CA, congenital, etc.) and the lifestyle, for a surgical specialty is much more benign than other surgical specialties.
Derm would also be a good choice, although the potential for procedures in the OR is pretty darn low, mostly office type of stuff.
ENT also has a great lifestyle, as does Urology (which is not a surgical SUB-specialty, but is considered one of the Core Surgical Specialties, along with General, Ortho, Neuro, ENT - ie, each having their own residency [not following after a Gen Surg residency]).
Things you wanna stay away from: Trauma/Crit Care, Neuro (lots of middle of the nights), Transplant (ditto and LONG operations), Vascular (same, lots of emergencies), just off the top of my head.
Hope this helps. Seriously consider Plastics - its a great field, with so much diversity in patients and work and if you aren't working in academics, your after-hours work will be seriously limited (making your family happy)> 🙂
