Then why'd they staple the skin, just cauterize it with the magic 2089 laser. My imagination says that when you cut completely thru some organ, the laser cauterizing trick doesn't work, the staples action says the writers believe that as well, but phuck it we've gotta keep this thing moving.

It stapled her tummy back together to keep her organs from falling out. You can't sew something together with a laser, only cut it apart. It wasn't set up for a female, so it wouldn't have known to staple the uterus back up anyway.
