Since mankind has appeared on Earth, we have constantly been evolving. Around 50 thousand years ago making their journey out of Africa humans took a great leap forward in their development, evolving physically, intellectually, emotionally and socially. With diverse civilizations and cultures created in the wake of human advancement. Our natural interest in innovation and technology has shaped our culture and our perception of each other and the world around us. Advancements in biomedical science have allowed us to alter this perception. Starting from the creation of the prosthetic limb people who have lost their motility and dexterity were able to regain their abilities. But it doesn’t stop there, recent and future developments have created bionic and alternative prosthetics that have allowed for improved physical abilities and aesthetic appeal. Technology has allowed us new means of human expression, has gifted the unfortunate with means of re-entering society and has allowed humans to reach new heights unfathomed in the years prior.
Evidence of early uses of prostheses date back to the ancient Egyptians. Early prostheses were mainly used for function, cosmetic appearance and a psycho-spiritual sense of wholeness (Thurston). The Greeks and the Romans were the first to develop true rehabilitation aid prostheses (Thurston). In the Medieval era prostheses were primarily used for battle and hiding deformity, they were heavy and crude and made of wood, metal and leather.
Ambroise Paré revolutionized prostheses in the 16th century with his inventions of both upper and lower limb prostheses. His “Le Petit Lorrain”, a mechanical hand operated by catches and springs and an above-knee prosthesis consisting of a kneeling peg and a prosth...

Modern technology has helped with the growth of many medical discoveries, but the original ideas all had to start from somewhere. One of the most famous surgeons in the medical world, Ambroise Pare is responsible for many of this generation’s practices. Ambroise Pare was born in 1510. He was a French surgeon, and later advanced to do his work as a royal surgeon for kings Henry II, Francis II, Charles IX and Henry III. From there, he went on to become one of the most influential people in medical work this world has seen. Because of him, many are still able to learn and grow from his teachings. Ambroise Pare impacted many people and ideas of medicine because of the innovative ideas he shared, the lives he saved, and the legacy he left behind.
Organisms are limited by the structure of their bodies. Some creatures are capable to do great things because of the number of limbs they have, or the density of their skin. Humans in particular are extremely reliant in the capabilities that our bodies bring to us. Our bodies however, are not all dependable, as we can injure ourselves, and even lose parts of our body. To combat this loss of body, the great minds of our species have created false limbs to replace what we have lost. This great improvement to our lives is known as, the prosthetic. In recent years this technology has expanded into a new form, that combines prosthetics and robotics to make life for people
In Frankenstein’s Cat by Emily Anthes, she talks about how humans change animals by biotechnology or adding limbs. The chapter “Pin the Tail on the Dolphin” discusses the many forms of prosthetics for animals. The prosthetics service animals from marine wildlife to a domesticated dog. A substantial focus zones in on a dolphin named Winter that loses her tail due to a fishing net that cut off the circulation from the tail to rest of her body. Two scientists come together to manufacture a fake tail for the dolphin. Eventually they invent a prosthetic tale that fits on Winter. Scientists even create prosthetic legs for animals such as dogs or flamingos. People construct beaks for birds and shells for turtles. Numerous uses of prosthetics benefit animals, but some seem more frivolous, like fake testicles for your neutered dog (122-142). I agree with Anthes on how prosthetics benefit animals by giving them a better life and allowing them to execute actions they could not before, but some prosthetic uses seem more for the owner’s comfort rather than
I picked an article on the prosthetic limbs, which are controlled by your own thought. The unique part of this prosthetic is that It has 26 joints, is controlled by the person’s own mind and has the power to curl up to a incredible 45 pounds. Imagine being able to control a prosthetic just by thinking about the next move. The limb has been described as Modular, which gives them the power to accommodate anyone in particular that has either the hand missing to the whole entire arm. It can be also used as a surrogate arm for those who have suffered a stroke and lost movement of their own arm. This just an incredible part of science that getting develop and study by John Hopkins University.
The idea of having an amputated limb and being able to receive a prosthetic limb within a few short hours is still a dream in today’s world. Scientists and researchers have made huge leaps and bounds in recent years, but prosthetic limbs have been around for decades. The oldest ever found was in Cairo, Egypt in the year 2000. It was a prosthetic toe made of leather and wood from 3000 years ago (Clements, 2008). This limb showed us that for the most part prosthetics have not changed a whole lot, but how they are made has improved. Prosthetic limbs can now be designed by using CAD/CAM, computer aided design and manufacturing. They can speed up the process it takes to make the limbs for patients. Clinical use of this process is still slow to get going in a lot of states and the world. The most important part of the prosthetic limb to the patient is not whether the limbs functionality is better, but the comfort of the socket. The socket is where the residual limb will reside in the actual prosthetic limb. When the handmade casts are used, it is hard to make a socket that will work well for the patient because it is hard to make an exact replica of the limb. That is why more funding needs to go to places that will teach people how to use the CAD/CAM design process and to help companies buy the expensive fabrication sites to actually make the limbs. Not only is the use of CAD/CAM a better process, but it is faster and will get the patients a better fitting limb that they will want to use more often.
With advances in weaponry came an increase in deaths and major limb injuries. During WWI the primary action was to amputate the limb rather than try and salvage it. This was due to the little time nurses, surgeons and anaesthetists had with each patient in the field hospitals, because they were overrun by more than double their expected capacity. There-fore, surgeons had to choose which critical patients to treat first, resulting in 41,000 ampu-tees during the First World War, all in need of artificial limbs (Pensions, 1939).
, from which time we have evidence of crude devices being made to replace a missing lower leg. These consisted of metal plates being hammered over a wooden core, which was then strapped to the stump of the remaining leg. These very early prostheses were usually made by blacksmiths, armor
There wasn’t much progress for centuries till World War I. Many soldiers were coming back home with severe injuries on their bodies. Since there were more and more people in need of these surgeries, reconstructive surgery started to develop even further. They came up with new techniques such as trying to rebuild entire limbs, ...
The materials in prosthetic limbs have always evolved along side technology, usually changing for the better. Prior to the development of electronics and plastics,
Limb lengthening surgery has come a long way since the days of the first procedures that took place in the early 1950's. What a ground-breaking idea it was to lengthen limbs. This surgery meant freedom for people who were afflicted with crippling disabilities. For those who had suffered the debilitating disease of polio - to congenital limb defects or dwarfism, the hope of having straight, longer limbs was a God-send.

Many great inventions have been made through research in biomedical engineering, for example, genetic engineering, cloning, and insulin. After insulin has been invented, there are still a lot of problems with the purity and the quantity of the insulin produced. Biomedical engineering devised a way to produce large quantities of insulin with a higher level of purity, which has saved a lot of human lives. Although biomedical engineering just been officially founded 200 years ago, its practice has been with us for centuries. According to The Whitaker Foundation website, 3,000-year-old mummy from Thebes, which uncovered by German archeologists, with a wooden prosthetic tied to its foot to serve as a big toe is the oldest known limb prosthesis and Egyptian listen to the internal of human anatomy using a hollow reed, which is what today’s stethoscope. No matter what the date, biomedical engineering has provided advances in medical technology to improve human health. These advances by biomedical engineering have created a significant impact to our lives. I have determined to become a biomedical engineer. Biomedical engineering will have a good prospect because it will become one of the most important careers in the future.
By convention, the field of healthcare research was entirely occupied by physicians and doctors. They were the ones who came up with new methods to treat diseases and get better results from diagnostic tests. Technology, on the other hand, was always looked at as a way to solve problems that we faced that didn’t pertain to the medical sector. It was employed to enhance the quality of life and make day to day work easier. But as technology progressed, so did the areas of application. The structural balancing techniques which were previously used to hold a building steady were now being used to develop near-perfect artificial joints and prosthetic limbs. Transparent polymers, developed to enhance robotic vision, were being suggested as a candidate for an artificial lens for the human eye. Before anyone could even understand what was happening, engineering had taken up the mantle to further medical technology to dizzying new heights.
Prosthetic limbs, one of the examples of physical enhancement, have improved to such an extent that the capabilities and...
