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.
