Once upon a time, in a land far, far away, lived a less than honorable ship captain who lost his hand during a sword fight with a young boy. The captain’s only option to replace his once very agile and useful hand was a simple iron hook. Although the story of Captain Hook and Peter Pan is not one based in fact, the existence of a hook-style prosthetic hand is no work of fiction. Thanks to the hard work and ingenuity of countless individuals spanning more than 2000 years, gone are the days where the well-known Captain Hook claw hand is the only hand prosthesis option.
Although select individuals continue to use a hand hook, there is a large variety in types, styles, and functions of hand prostheses commercially available on today’s market. Two of these hand prosthesis options include the i-limb Ultra and the Vanderbilt Multigrasp. One of the up-and-coming models of hand prostheses is the bebionic3 designed and produced by RSLSteeper. It is necessary to discuss information regarding the technology, biomechanical basis, functional abilities, suitable population, financial cost, metabolic cost, equipment specifications, and therapy’s role, to more fully understand this product.

bebionic3 Technology:
The bebionic3 is a type of myoelectric prosthesis. A myoelectric prosthesis is custom-made to fit and attach to the remaining limb of the user (either above the elbow or below) with maximum suspension using suction technology. Once attached, the prosthesis uses electronic sensors to detect muscle, nerve, and electromyography (EMG) activity. It then translates this m...

- Prosthetic Limb Essayexplanatory essayI 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.

Throughout the years, since the first invention, people have been developing and enhancing limb prosthetics to produce a device that would be functional and aesthetically pleasing for people who have had amputations. There are many materials that have been used to manufacture limb prosthetics, such as wood, copper, and bronze, but nowadays, lighter materials, namely carbon fiber are being used for comfort. Because of prosthetic enhancements, the perceptions of people toward amputees have shifted from negative to positive; people are becoming more appreciative rather than

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.

This paper will outline the advanced technology of bionic limbs. These bionic products combine artificial intelligence with human philosophy to create a more human-like way to restore the function of a lost limb. These bionic limbs take the pressure off amputees by sensing how their lost limb should move and adapts to movement of the amputee. The bionic product automatically controls itself without the amputee having to think about how to move it. The purpose of this paper is to inform about bionic products. It will further explain how they operate, along with their efficacy in prosthetics. Innovative bionic technology continuously increases the quality of life for amputees. That innovative technology will be explored through this paper, along with their specific functions and operations. The new products like the Power Knee, the Rheo Knee, the Propio Foot, and Symbiotic leg allow more mobility and individualistic movement for the amputee. Each was developed and tested to be efficient in the prosthetic world. I will explore case studies of people who have these products. I will explore the struggles and adaptions they had to make with the use of this technology.
