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

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
