Two Belarusian Men Invent Simple Prosthetic Arm
Accidents in which people lose an arm or leg often take place in communities with large numbers of poor people.
In such areas, victims may not have enough money to pay for costly prosthetic replacements. But two men from Belarus have used simple and easily available materials to make a prosthetic arm. Almost anyone can build one of the limbs at home.
Oleg Galtsev was four years old when his father Sergei lost his arm in an explosion on a military firing range. At the time, Sergei Galtsev was an army captain in the former Soviet Union.
Almost 30 years later, he is using a prosthetic arm designed by his son and another engineer.
He says "They gave me the prosthesis to test for three weeks. I used it to saw firewood, cut the grass and to do many other things in the field."
The mechanical arm looks nothing like the new prosthetics available in industrial countries. But it is easy to make, has a low cost, and does not need much maintenance.
Oleg Galtsev says the device is designed for people who do not feel at ease with electronics.
Galtsev says it took two years to design the prosthesis. They used a 3-D printer to create some parts and bought others online.
The creators did not ask for a legal patent to control ownership of the device. In fact, they have published directions on how to make it online. They say it costs just one-tenth of the price of other mechanical prostheses.
Sergei Galtsev says he can now perform many outdoor activities, including using a chain saw to cut tree limbs.
"I am proud that my son decided to tackle this problem. There are many people who really need this device in their daily lives."
Oleg Galtsev says many people have watched videos of his prosthetic arm invention on YouTube. He says he hopes his work will influence others to invent new prosthetic devices.

在一些落后的地区，伤患可能无力承担昂贵的假肢置换费用 。不过，两名白俄罗斯人却用简单、易得的材料发明了假肢 。几乎所有人都可以在家自制假肢 。
奥列格·盖尔特瑟夫（Oleg Galtsev）4岁时，他的爸爸赛奇（Sergei）在军事火练靶场的一次爆炸事故中失去了一条胳膊 。当时的赛奇是前苏联任军队上尉 。
赛奇说，“他们把假肢送来让我试用三周 。我用假肢砍柴、割草还能干很多农活 。”
这只假肢看起来一点都不像工业化国家新制造的义肢 。但是这种假肢制作方法简单，成本低廉，而且不用定期保养 。
盖尔特瑟夫还称，设计这款假肢耗时两年时间 。假肢部分零件是用3D打印机制作完成的，剩下的零件是在网上购买的 。
两位设计师并未申请专利来宣告假肢的所有权 。其实，他们已经将制作步骤发布到网上了 。他们称，这款假肢的制作成本仅是其他机械假肢价格的十分之一 。
“儿子决定解决这个问题，让我深感自豪 。在日常生活中，很多人都需要这套装置 。”
盖尔特瑟夫称，很多网友在YouTube上观看了假肢制作的视频 。同时他还表示，希望自己设计的产品可以鼓励其他人发明更多新型假肢 。
