i-Limb Ultra • Functional prosthetic hand. • Touch Bionics most advanced prosthetic. • Based off of the i-LIMB Pulse design. • “the most versatile prosthetic hand available” – Touch Bionics
What it can include • Fingers that move independently and bend at natural joints. • Manually rotatable thumb. • Multi-flex wrist option or manually rotatable. • 4 skin coverings: 2 active and 2 natural. • Variety of automated grips along with custom gestures. • Upgraded biosim software.
How it works • Electrode mounted on residual limb. • User tightens muscles, this generates an electrical impulse. • Impulse sent to computer on board the prosthetic. • Based which muscles are fired the hand will open or close. • Requires some prepositioning of fingers for some actions.
Positives • Individual has a hand to help assist them. • Provides them the ability to do daily activities. • Individually moving fingers allow for better grip. • Patients say it can help psychologically.
Setbacks • Cost: $18,000 per prosthetic. • Although versatile, does require some prepositioning for some actions. • Engineering: - Gears: without force will reverse. - Skin: Balancing Hardness and Elasticity.
