Why can't you just bypass affected tissue in major hemorrhages?

Pretend this is an arm and my anatomy is okay.

So supposing a large vessel got a lac, why can't we just reroute the blood with some needles and tubing and bypass effected areas?

I know ischemia following hypoxia is a concern, but isn't that the same if we don't stop the bleeding?

I know in complex injuries that involve a lot of layers and vessels this probably isn't feasible, but I guess for the occasional moderate case?

Probably a dumb idea, but it's been floating around in my head enough that I'd like someone to dismantle it.

Take a cooked spaghetti noodles. Cut it in half. And using pliers for hands stitch it back together in the back of a truck going down a washboard road. Oh and covered in butter!

Okay but why not us in the field?

Especially when transport time is longer, like rural areas?
Because you need anesthesia, sterile fields, surgical instruments, assistants and a surgeon to do what you're talking about. This should give you some idea of the technical realities:

Nvm the fact that 3 doctors are in this video opening credits shows me I underestimated what it takes

I guess in my head I had it as two large bore needles/catheters, tegaderms and some tubing. 🤷‍♀️
