Power
With the thumb opposed, all four fingers close into the palm
until they meet resistance or the close signal stops. When
fingers are approaching a fully closed position, the thumb drives
in to cover the fingers for additional grip security. This pattern
allows round objects such as a ball or a piece of fruit to be held
securely. This grip can also provide a handshake. Cylindrical
shaped objects such as bottles, home and garden utensil
handles are also held easily and securely.
Tripod
When the thumb is opposed, the hand closes into Tripod Grip
with index and middle fingers meeting the thumb. Ring and little
fingers continue to close until they meet resistance or the close
signal stops. This type of grip allows users to pick up, hold and
manipulate a variety of everyday objects such as car keys, coins,
jar lids and pens.
Hook
With the thumb in opposed position, a partially closed Power
Grip provides Hook Grip. This is ideal for carrying a shopping
bag or briefcase. Hook Grip can also be achieved by closing the
fingers from the relaxed hand position.
Finger Adduction
The fingers of the bebionic hand move together naturally as the
fingers close. This allows the user to securely grip thin objects,
such as cutlery or a toothbrush, between the fingers to achieve
function in a different plane. Finger Adduction is most functional
with the hand in Power Grip but can also be achieved with the
hand in Key Grip and Pinch Grip.
