Homemade prothesis hands

The year-old woman lost her leg in a freak accident early in when her foot was crushed while she changed the brakes on her car. Now, she is an internet phenomenon. Stevens, who is an occupational therapist, said that she got the inspiration for the Lego stunt from a colleague who jokingly suggested it.

However prosthetic finger attachments can restore the ability, the look, and the usage of having real fingers. The prosthetic finger was created to give someone the use of a fully functioning hand.

The person could have been born without a finger or fingers, lost the finger in an accident, or had the finger amputated for another reason.

Therefore, the use of medical technology has made it possible for someone to play the guitar again using prosthetic finger attachments, or other tasks that we use our hands for.

One of the most amazing things about our fingers is how we use them to hold objects, play an instrument or even give a handshake.

The fingers are controlled by the brain. The finger digits do not have muscles in the same way the arm or leg would.

Instead they are a collection of tendons, nerves, and blood vessels. The only muscles that are in the hand are located within the palm of the hand, etc. The fingers are composed of bones called the phalanges with three joints in between. There is also a nerve and artery running along the side of the outer edges of the bone.

Below the bones are the tendons that move the fingers.


These tendons are the two flexor digitorum superficialis and the one flexor digitorum profundus. Therefore, the flexor superficialis will bend the finger at the proximal joint, whereas the flexor profundus will bend the finger at the distal joint.

When a person wants to pick up an object, the brain will send messages using the ulnar and radial nerve to the muscles in the palm that move the hand. The nerves will activate the muscles to contract the tendons. The tendons will bend the fingers at the appropriate joints to curl the fingers around the object.

The muscles in the arm and forearm will then be used to pick up the object, after the fingers have tightened around it. When a person is to be given a prosthetic finger, the physician will first have to look at the reason the finger was lost. He will also consider how much of the finger can be replaced with a prosthesis.

Therefore, it is possible to have only a prosthetic finger placed on at the promixal finger joint or whole finger prosthesis can be placed on.

The main task during a placement of prosthetic finger attachments is to ensure that nerve signals from the muscle in the hand are programmed correctly for the person to move the replacement finger.

The prosthetic finger is often made of metal, wires, and covered in silicone to give the appearance of skin. When the prosthetic finger is to be fitted, several measurements and skin color comparisons are made to achieve a very realistic prosthetic device.Homemade Prosthetic Hand Project September 27, September 27, - by Miranda Hansen - Leave a Comment There are a variety of very cool DIY animatronic hands online, however for this project I wanted to build something that could be reasonably applied as a prosthetic.

Oct 20,  · To make a fake hand, start by getting a paper plate, tracing the outline of your hand on it, and cutting the shape out.

Next, cut 19 pieces of plastic straws at a length of inches each.

Additionally, cut a small “v” in the middle of each straw so it can bend%(34). You should be able to build an artificial hand that can pick up light objects, such as ping-pong balls, empty plastic bottles or small stuffed animals. It will be difficult to build a hand . Therefore, the use of medical technology has made it possible for someone to play the guitar again using prosthetic finger attachments, or other tasks that we use our hands for.

Cardboard, String, Rubber Bands and Prosthetic Hands Eighth-graders at North Middle School spent the week building functioning prosthetic hands with household items.

It was a test of creativity.
