The bebionic hand provides 14 different grip patterns, allowing the user to have a more complete device to assist them in their
day to day life. The hand has two selectable thumb positions: opposed and
non-opposed.
Opposed places the thumb in opposition to the fingers on the hand, allowing grips like Tripod and Power.
Non-Opposed places the thumb parallel with the fingers of the hand and allows grips like Key and Finger Point.
Opposed Non-Opposed
2.0 bebionic Grips
The hand is supplied preset in Mode 4. This provides two input
operation with proportional control of grip and speed. Speed
and grip force are set to maximum.
To alternate between the default and alternative grip pattern,
an OPEN OPEN signal must be applied (i.e. the hand must be
fully opened, the signal relaxed and then a second open signal
supplied). To alternate between the primary grip pattern table
and secondary grip pattern table, press the Program Switch for
less than two seconds. The Auto Grip feature is turned off.

2.31. Thumb ML Adjuster 2.32. Thumb Contact Point Adjuster
An adjuster has also been provided to alter the baseline position
of the thumb, in order to optimize the contact point of the thumb
tip against the opposing finger(s) for Tripod, Pinch and Precision
Grips. This is done by moving the thumb either towards the palm
or away from the palm. This adjuster is located under the thumb
bracket as shown above. Using a hex drive the adjuster should
be turned clockwise to move the thumb towards the palm and
counterclockwise to move the thumb away from the palm. The
effect will not be observed while making the adjustment and can
only be observed by resetting the hand i.e. switching the hand
OFF and ON again.
An adjuster is provided to allow repositioning of the thumb for
contact with either the index and middle fingers, as in Tripod
Grip, or with index finger only, as in Pinch and Precision
Grips. The thumb pivot assembly is fitted with a slotted screw
as shown above. This acts to adjust the friction on an internal
clamp and is loosened by making two complete turns and
pushing the screw inward. With the clamp slackened the
thumb position can be manually repositioned. The assembly
must be retightened before electrically driving the thumb.
A Program Switch is provided on the back of the hand. This has four functions;
1. Switch the hand ON and OFF
A single press for approximately three seconds will switch the hand OFF. A single
press for more than two seconds will switch the hand ON.
2. Alternate between the primary and secondary grip patterns
When the hand is switched ON, a single press of less than two seconds will alternate between
the primary and secondary grip patterns. This will be accompanied by a short bleep and
vibration (if activated on bebalance).
3. Enable / disable the in-hand bluetooth module
With the hand switched ON, a single press for more than six seconds will enable the bluetooth module. A double beep/vibrate
will indicate connection has been made.Pressing the switch again for more than two seconds or disconnecting the power to
the hand will disable the bluetooth module.
4. Enter / exit glove mode as follows
With the hand switched OFF, press the switch until the thumb begins to drive in. Then release the switch. For more information
please see page 20.
Thumb adjustment MUST be completed
by a qualified technician or practitioner
CAUTION

2.2 Program Switch
2.3 Thumb Adjustment
To achieve certain grips it is necessary to adjust the thumb position.
There are two different planes to move the thumb in,
as detailed below.
08
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.
Grips
2.4 Opposed - Thumb in opposition to the fingers
09
Active Index
With the thumb opposed Active Index Grip will grasp the handle of an object
with the middle, ring and little fingers and secure the grip with the thumb.
The index finger will then close – this may be positioned over the lever of
the device held such as a spray bottle, it also offers the ideal finger position
for typing. The index finger is under independent user control and may be
positioned accordingly. To exit Active Index, an open signal will fully open
the index finger before the other fingers and thumb release their grip.
The bebionic hand MUST NOT be used to operate a firearm.
SERIOUS WARNING
Precision Closed
This grip can be used in situations similar to the Precision Open Grip, but
where extended fingers would be obstructive, such as working at a desk.
Initially the middle, ring and little fingers close into the palm. The thumb
moves to the midpoint of its range and pauses. The Index is then active and
under user control.
(To achieve this grip it is necessary for the thumb to be manually
repositioned by the practitioner/technician so that the thumb only contacts
the index finger.)
Precision Open
With the thumb opposed, the index finger meets the static thumb allowing
the user to pick up and manipulate small objects. When this grip is selected
and a close signal is applied, the thumb closes to the midpoint of its range
and pauses. The index is then active and under user control. The middle,
ring and little fingers remain extended. (To achieve this grip it is necessary
for the thumb to be manually repositioned by the practitioner/technician so
that the thumb only contacts the index finger.)
Pinch
The thumb only contacts index finger and is used for the fine manipulation
of objects. To achieve this grip it is necessary for the thumb to be manually
repositioned by the practitioner/technician so that the thumb only contacts
the index finger (See section 2.3).
10
Finger Point
With the thumb in the non-opposed setting, the user can move to Finger
Point position. The middle, ring, and little fingers close against the palm
and the thumb moves against the middle finger. With this grip, typing on
a keyboard or input pad, pressing a bell or a button can be achieved.
Key
In the non-opposed thumb position, the four fingers partially close. The
thumb then closes onto the side of the index finger. The thumb position
may be raised and lowered without moving the other four fingers
allowing for release, capture or reposition of the object being gripped.
This pattern is ideal for carrying paper or letters, using a spoon and for
holding a thin flat object such as a plate, a credit card or a key.
Grips
2.5 Non-Opposed - Thumb is parallel with the fingers
Open Palm
With the thumb in the non-opposed position the hand may be fully
opened to provide a flat palm suitable for carrying a tray or a plate.
