Nature created the human body is beautiful in every way, but sometimes, in critical situations, it becomes necessary to replace some parts of prostheses. And it's not always an arm or leg:
1. octopus instead of hands
For those who are ordinary human limbs seem too banal, there is another alternative. Developer prostheses Kaylee Kay created a prosthesis for the hand, which wraps around objects modeled on the tentacles of an octopus. The prosthesis is driven by a special mechanism, and you can use it to take and hold items of different shapes.
2 mermaid tail
In most cases, people actually replace the existing bodies, but some patients are rare ingenuity - who lost his legs Nadia Vassy from New Zealand, for example, prosthetists stunned request to do her mermaid tail. Once I saw a little boy in a pool of her normal prosthesis that child is very interested. Nadia joked that she actually - a mermaid, but to live among the people it is sometimes necessary to wear artificial legs. This idea of herself so much that she decided to really get a tail. In her request was made chic prosthesis: a flexible backbone is made of plastic and leather Lycra. Nadia says that swimming with a tail - a pleasure.
3. Functioning eyeball
Several researchers have developed artificial eyes, perfectly ordinary glass eye, and may soon lose an eye will be able to see people again. Many of these prostheses operate retinal function by converting light into electrical impulses. System bionic eye of Second Sight, for example, uses a tiny camera which can "see" the world surrounding the person, and the computer converts the data received from the camera into electrical signals that the brain can process. In 2013, in the British scientific journal Journal of Ophthalmology published the results of a study in which 21 patients received blind the opportunity with the help of this device to find and identify objects and even read short words.
4. Replace the nose
The first prosthetic nose appeared a long time ago, when the Danish astronomer Tycho Brahe lost his nose in a duel, and replaced it with a clumsy metal version. Who prosthetic nose become much more sophisticated. Specialists at University College London have developed a technology that allows to grow the nose with mucous membranes and tiny blood vessels.
First manufactured glass shape, with which makes polymer "skeleton". Then, the stem cells are added, and the future is placed in the nose stimulates the development of cell bioreactor.
In the next step the nose sewn into the patient's arm, wherein the process of forming fabrics. And finally, the last stage - ready to transplant the nose on your face and add mucosal cells, which makes the new organ function.
5. The prosthetic penis
Men with certain delicate problems or erectile dysfunction such a prosthesis can completely change the life. Some of these implants are mimic a state of constant erection, others are more complex: to achieve the status of an erection is necessary to compress the pump located in the scrotum, causing the penis to the location of the cylinders supplied special liquid. When the need for erection disappears, just click on the exhaust valve and the cylinders deflate.
