Does this make you cringe?

I'm writing a horror novel about a bunch of sick people getting a taste of their own medicine. One particular character is a mobster who kills little children and sells their organs and body parts on the black market. Yes, this stuff really does happen. Anyway, I designed this device just for him called "the chiropractor." It's a hydraulic machine that consists of several metal rectangles connected by hinges. You strap the individual to the chiropractor. The open spaces where the hinges adjoin are there the person's joints go. All the parts turn any direction 180 degrees until they're flush against each other. They bend all the person's joints backwards and sideways. It turns their ankles and wrists inwards until they're touching their inner forearms and forelegs. It hyperextends the knees and elbows until they're flush against their quadriceps and triceps. Then it hyperabducts the hips and shoulders until the outer thighs are flush against the rib cages and the shoulders are separated. Alas, it bends their spine backwards until it snaps like a toothpick.
