Prosthesis

A US$270 programmable, 3D-printed electromyographic prosthetic hand may soon change the li...

A PhD candidate and six undergraduate students at the University of Illinois at Urbana-Champaign (UCIC) have created a low-cost, programmable, 3D-printed prosthetic hand that may soon change the lives of amputees in Ecuador. The hand costs just US$270 to manufacture, making it a small fraction of the cost of a typical prosthetic of this type.  Read More

A 3D printed model of the patient's jaw helped surgeon's overcome problems posed by his in...

While the idea of cruising around in a 3D-printed car and munching on 3D-printed chocolate before returning to a 3D-printed home sure is nice, no industry is poised to benefit from this burgeoning technology in quite the way that medicine is. Replacing cancerous vertebra, delivering cancer-fighting drugs and assisting in spinal fusion surgery are just some of the examples we've covered here at Gizmag. The latest groundbreaking treatment involves an Indian cancer patient, who has had his upper jaw replaced with the help of 3D printing.  Read More

The Moto Knee is a prosthetic leg designed for a variety of high-impact sports

You probably wouldn't try using the same motorbike for both racing over rough trails and commuting on smooth roads, so ... why use the same prosthetic leg? That's the thinking behind the Moto Knee, a prosthesis that's designed for activities such as skiing, horseback riding, cycling and motocross. In order to withstand the impacts that come with such activities, it even incorporates a Fox DHX Air mountain bike shock absorber.  Read More

Touch Bionics has unveiled the latest enhancements to its i-limb Ultra Revolution at OTWorld 2014 International Congress. Users can now set and assign different grips for different objects and configure the prosthetic hand via Android apps.  Read More

Many modern prosthetic limbs are so intricate that they seem like something from the sci-fi cyborg realm. Unfortunately, to the wearer these marvels still feel like lumps of dead metal and plastic. DARPA's recently announced Hand Proprioception and Touch Interfaces (HAPTIX) program aims to change this. Using implantable sensors linked wirelessly to external modules, the goal is to provide lifelike prosthetic limbs with such a high degree of sensory feedback that they bring a sense of being part of the the wearer’s body, not something just strapped on.  Read More

Although computer-controlled artificial legs have been around for a few years now, they generally still feature an ankle joint that only allows the foot to tilt along a toe-up/toe-down axis. That's fine for walking in a straight line, but what happens when users want to turn a corner, or walk over uneven terrain? Well, in some cases, they end up falling down. That's why researchers at Michigan Technological University are now developing a microprocessor-controlled leg with an ankle that also lets the foot roll from side to side.  Read More

Artist’s concept of a flat interface nerve electrode (FINE)

Artificial limbs have come a long way in recent years with the development of prostheses that can be controlled directly by the patient’s nerves. The problem is, links between living nerves and the prostheses break down over time, which makes permanent attachment and practical control difficult. To understand why this happens and to help give patients more control over their prostheses, DARPA has instituted a number of programs aimed at improving neural interfaces and allowing amputees to have better control of advanced prostheses in the near term.  Read More

The i-limb is controlled by a smartphone app

Whichever marketing genius came up with the Apple catchphrase, "There's an app for that," has a lot to answer for – or brag about. It's heard so often these days that it’s become a cliché. Touch Bionic’s i-limb ultra revolution robotic artificial hand gives yet another reason to repeat the phrase. It’s linked to a smartphone app, which allows for greater control of the hand, including the ability to program it to suit the wearer’s personal needs.  Read More

Argus II consists of a tiny video camera mounted in glasses that is wirelessly linked to a...

While the word prosthesis usually evokes images of artificial legs, arms, and these days even sophisticated thought-controlled hands, an entirely new class of replacement body part has now become a reality – the bionic eye. One of the pioneers in this field is California-based Second Sight and the company has now announced that its Argus II System has received U.S. market approval from the Food and Drug Administration (FDA).  Read More

The basic components of the Argus II Retinal Prosthesis, used in the experiment

Second Sight’s Argus II Retinal Prosthesis is definitely an interesting piece of technology, allowing a blind user to “see” objects, colors and movement in their environment. Ordinarily, this is done with the help of a video-camera-equipped pair of glasses worn by the user. In a recent experiment, however, researchers bypassed the camera, transmitting visual braille patterns directly to a blind test subject’s retina.  Read More
