Wildhorse, the best tool to prevent intestine puncture would be a knife with a gut hook feature. It's not really necessary, but that's what I would recommend. Even if you nick or cut the intestines, so what, open up the cavity quickly and flush with your charged garden hose. Really it's no big deal. I my photo I nicked the stomach lining and a portion of the intestine peeked out. During deer season we teach young hunters how to dress a deer, plenty of mistakes there, just clean and cook the meat properly, enjoy. Now if I had cut the intestine in half than I would have cancelled all photos and opened the stomach quicker and dumped the guts into the blue container. Either way there really is no panic needed. Keep in mind when you visit your local market, the products you buy are a gamble, you have no information about their beginning nor their ending. By breeding and raising your own meats and veggies you are now in control and have eliminated hidden variables and question marks.
