Disabled man creates prosthetic hands for himself

The innovation consists of a pair of metal hands and arms which can grip and hold thanks to a series of wires and pulleys inside the shell.

Sun was creating a bomb to help him fishing when it exploded prematurely, causing him to lose both hands.

Since he couldn’t afford the hospital's prosthetic limbs and he needed to work, he decided to invent prosthesis for himself.

“I survived but I had no hands and I couldn't afford to buy the false hands the hospital wanted me to have - so I decided to make my own,” he explained.

After eight years of development and prototyping, he finally had a solution.

“I control them with movements from my elbows and I can work, love normally and feed myself just like anyone else. The left arm transfers power from the natural movement of my elbow into the finger, allowing it to grab and hold… rotating the two bones that I have left in this arm allows my right hand to open and close,” he explained.

According to Sun, the only problem is that the hands are heavy (each hand weights around 1 kg).

“The only drawback is that steel is quite heavy so they're tiring to wear and get hot or cold in the extremes of summer and winter,” added Sun.

The farmer intends to improve the design so he can help other similarly disabled people, and he is selling this innovation for about $500. Up until 2013, he had already sold about 1000 hands.

“I made this from scrap metal for virtually nothing. There is no need to pay hospitals a fortune”, he stated.
