In the human world, world peace seems to be an unattainable ideal. Compared to the last century, although there seem to be a lot of peace on the surface, there are still many regional conflicts and wars. The effects of these war conflicts are different from diseases, and the disease can be cured, but the damage caused by war may never be calmed down. Some of the victims of the war are lucky enough to save their lives, but they may have to face bigger problems, traumatic or defective external limbs. Psychological trauma takes time and everyone's efforts to calm down. Victims with defects in appearance and physical function cannot return to their original appearance in their lifetime, and their lives are affected. They must also bear the same vision. Like a two-year-old Israeli girl, she was killed because a terrorist drove into a crowded bus stop in Jerusalem. She survived, but under the doctor's efforts, her left foot still needs amputation. The good news is that thanks to the rapid progress of science, there are several companies that are committed to developing a body part that can be completely replaced. Although it takes some time to reach the goal, the little girl has the opportunity to use it in her adulthood. Brand new feet to walk. The replaceable limbs that people used to dare not think about may never be an illusory dream. In addition to Israel, the biomedical innovations include the United States, the Netherlands, Iceland, and the United Kingdom. The following will introduce five companies that are committed to the development of alternative limbs that will reinvigorate countless people in the future. ReWalk (Israel) ReWalk literally means “walking again.†The company, formerly known as Argo, was founded in 2001 by Dr. AmitGoffer, a quadriplegic surgeon who uses thick extracorporeal stents to help people who are undergoing physical therapy or spinal cord injuries. In vitro mechanical stent development company accredited by the US Food and Drug Administration (FDA). ReWalk became a publicly traded company in September 2014. It has plunged from a price of $43.71 per share, but it was again in the last month because of the cooperation of the US Veterans Affairs Office (VA), which led to a sharp rise in ReWalk's share price. O ssur (Iceland) The leadership role played by this company must not be ignored. Unlike traditional accessories, the mechanical aids made by Ssur are based on batteries, and the wearers do not need to use more normal walking. Strive to walk, so as to prevent strain caused by excessive use of muscles. Not only does Ossur's goal stop there, they are testing new aids that link to the user's peripheral nervous system. Currently this test is being conducted in a small number of customers, and it is hoped that the new aids can be controlled by the user's ideas. This innovation is not only the implementation of ?ssur, but ?ssur can make the time delay of the nerve signal from the human mind to reach the aid is almost removed, the technology is to combine the wired and wireless signals, so that the brain signal is transmitted to The time required for the aid is almost equal to the time required to reach the normal limbs. In this way, the function of the auxiliary device and the normal limb can be greatly improved, so that the auxiliary device gradually achieves the effect of complete replacement.
