1.2 Principal Dimensions and
Specifications

The bebionic small hand provides 14 dierent 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 o.

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.
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 eect 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 hex screw as shown above. This acts to adjust the endstop of the thumb when in the opposed position.
To adjust the position of the thumb, first loosen the adjustment screw to allow free rotation of the thumb.
Reposition the thumb to the optimum tripod or pinch position, and retighten the adjustment screw to set the
new position.
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 dierent planes to move the thumb in,
as detailed below.

8
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 dierent 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

9
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.
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).
The bebionic hand MUST NOT be used to operate a firearm
SERIOUS WARNING

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.
