Carlos was a factory worker like a lot of people.
But, unfortunately, Carlos suffered a major accident at work.
His hand was pulled into a machine, like the one below.
After screaming several times, an operator finally came to his rescue.
But upon freeing his hand from the machine, he quickly realized that he was facing a major problem.
All the skin had been ripped from his hand. In addition, he lost two fingers, all the veins, and the nerves.
Originally, doctors feared they would have to amputate.
But thankfully for Carlos, one doctor was determined to save his hand.
