History of Prosthetic Limbs
Prosthetic limbs have been around for 3000 years.
Typically made of iron or wood.Served no real purpose. Insertion was crude.Until recently, prosthetics utilized hooks.
Hook Hands
Hooked prosthetics are controlled manually.
Incorporate a pulling system.
Very limited in function.
The First Commercial Active Prosthetic
Touch Bionics I-Limb Ultra™Developed by David Gow of the Scottish
National Health Service and built by Touch Bionics™
Major advance on previous hooked limbs.Became commercially available in 2007.
How It Works
Sensors are imbedded in the arm.Impulses from the brain are read.A microprocessor controls each finger
individually.Determines the amount of force necessary to
grasp an object.
Future
Other Bionic Limbs -Shoulders, Wrists, Elbows
Smaller Price Tag -Currently: $48,000.
Greater Force Exertion
