A prosthesis from wrist to finger

Can be equipped with electromechanical prostheses. At present, the most advanced prosthesis in the world is intelligent bionic prosthesis, which can be reserved at present.

On July 23rd, 2007, Juan arredondo, an American soldier who lost his left hand in the Iraqi war, demonstrated the function of a new bionic prosthesis.

A bionic hand that can perform complex movements that ordinary prostheses can't, was first marketed in Britain. According to the British "Daily Mail" reported on the 20th, this bionic hand named i-LIMB allows users to smoothly perform fine movements such as unlocking, entering passwords and opening cans, which is as flexible as a real hand.

I-LIMB bionic hand is made by Levin Si Tong's bionic contact company in Lothian, England.

Dr David Goh, from the Scottish National Health Service.

The bionic hand is connected with the user's arm through the arm sleeve, which is equipped with a rechargeable battery and a pair of electrodes. When the user has the idea of moving his hand, the brain signal will be collected by the electrodes in the arm sleeve. The electrodes transmit brain signals to the microcomputer located on the back of the bionic hand, and then the computer sends instructions to the motor nerves on the fingers, thus making the fingers move.

This bionic hand is made of light plastic commonly used in automobile engine parts, which is lighter than the real hand, and is covered with a layer of high-fidelity artificial skin with beautiful appearance. high function

Ordinary manual workers usually have only one motor nerve and can only perform some simple actions, which is difficult to meet the user's requirements for unlocking and inputting passwords. The five fingers of the I-limb bionic hand have 1 motor nerve, so it can complete more delicate movements, which perfectly makes up for the shortcomings of similar products and brings great convenience to users.

The wrist of the bionic hand can move freely, and all five fingers can rotate freely and move independently. Can successfully complete unlocking, lifting glass, supporting board and other actions. Even detailed actions such as entering a password and opening a can are difficult.

The new bionic hand is currently on sale in limited quantities at a price of 8,500 pounds (about 65,438+7,000 US dollars).
