The Technology of Today (and What to Expect in the Future)
According to Which-50: “11 million children and adults globally face a life without a hand, arm, foot, or leg due to war, diabetes, cancer and trauma.” It’s therefore more important than ever to carry on research that is fundamental to the advancement of prosthetic technology.
So far, this research has led to significant progress. Businesses like Next Step Bionics & Prosthetics provide the most progressive technology in the industry by working directly with manufacturers. The company offers products such as the BiOM Ankle System from iWalk, a prosthetic designed to improve mobility via propulsion technology while reducing stress on the body.
3D-printed prosthetics are also becoming more common. They’re not as cost-prohibitive as other high-end prosthetics, making them sustainable and easy to tailor to different individuals. They’re also heavily used in developing countries where most citizens can’t afford expensive medical prosthetics. LimbForge have been creating and printing 3D models of arms, elbows, forearms, wrists and hands from a plastic material which can be easily adapted to the wearer.
UK-based company Open Bionics are also creating 3D-printed limbs for the NHS which can allow amputees to write, walk and shake hands again. Not only are they aesthetically desirable, but they’re also cost-effective.
The brain will be key to developing even more complex prosthetics that increasingly resemble natural limbs. Cathy Hutchinson, a quadriplegic 58-year-old woman, was able to lift a bottle to her mouth to drink after researchers at Brown University connected a robotic arm to Hutchinson’s neural network. In 2012, Zac Vawter climbed up the 103 floors of the Willis Tower in Chicago by walking up the stairs while wearing a prosthetic leg connected to his brain. While myoelectric limbs, which convert muscle movements to electric signals, have become a lot more common in the past few years, thought-controlled prosthetics may very well be the future of medical prosthetics. They’re capable of offering the closest approximation to natural limbs, especially in regard to functionality.
Prosthetics are not just limited to limbs, however. Researchers have already been able to replace certain organs in the body with artificial ones, like the pancreas. This has the possibility to become a widespread treatment for type 1 diabetes (or even the prominent method) after a successful trial where 29 patients were given an artificial pancreas.
Springs and Prosthetics
Springs have always played an important role in the functionality of prosthetics, and not just recently. In fact, even during the Middle Ages, it was possible to find tradesmen capable of crafting prosthetics with gears and springs to improve the functionality of the limbs.
Modern body-powered prosthetics, such as artificial arms, use cables and harnesses that react to muscle movements. A type of body-powered prosthetic system called ‘voluntary opening’ relies on elastic bands or springs for gripping force.
Prosthetics have changed immensely from uncomfortable wooden limbs to high-tech prosthetics that are capable of moving like natural limbs through implants in the brain. With new advancements made in the field of prosthetics and bionics, it’s not that far-fetched to believe that we’re moving towards the bionic human. 彈簧展-2019第二十屆廣州國際彈簧工業展覽會-全球最大彈簧展會-巨浪展覽 -The 20th China (Guangzhou) Int’l Spring
