bebionic hand
Benefits at a glance
Aesthetic design
The aesthetic hand design is based on the anatomical skeletal structure of the human hand. Impressive design features include the natural-looking shape of the joints and the transition between the wrist and back of the hand.
Modern look
The bebionic hand is available in two colour versions: a white Kevlar look and black carbon look.
Numerous different grips
Individually and independently driven fingers enable fourteen selectable grips, so you can perform a large number of everyday activities with ease.
Individually adjustable
The O&P professional sets the parameters of the bebionic hand individually in the adjustment software to fit your needs and situation.
Optimum weight distribution
The arrangement of the finger motors near the wrist leads to a natural, balanced distribution of weight so the hand is lighter and more comfortable to wear.
Synchronised finger movements
Sensors in the motor control system allow the coordinated and synchronised movement of the individual fingers when grasping.
Grips
Active index grip
The active index grip is the ideal hand position for using a keyboard. Objects are grasped and held with the thumb, middle, ring and little fingers, and the index finger subsequently bends. You can then control and position the index finger independently.
Power grip
This grip enables you to hold round or cylindrical objects more easily and, above all, more securely. This includes not just balls or pieces of fruit, but also bottles or the handles of household utensils. The power grip also lets you shake hands.
Pinch grip
The pinch grip is especially useful for the fine handling of objects. For this purpose, ask your O&P professional to manually reposition the thumb so that it touches only the index finger.
Hook grip
The hook grip is ideal for carrying a shopping bag or a briefcase. Two options are available for this grip: either with the thumb in opposition and a partially closed power grip, or by closing the fingers from the relaxed hand position.
Precision closed grip
This grip is similar to the precision open grip, but is particularly suitable for situations where extended fingers would get in the way – for instance when working at a desk. The middle, ring and little fingers are bent first and close into the palm; the thumb then moves to the midpoint of its movement range and pauses there. After that, you have full control of the active index grip.
Finger adduction
The fingers of the bebionic hand move together naturally and simultaneously as they close. This allows you to grip thin objects, such as cutlery or magazines, between the fingers more securely for a uniquely confident grasp. Finger adduction performs especially well with the hand closed. It can also be used together with the key grip and pinch grip.
Tripod grip
This grip allows you to pick up, hold and manipulate a variety of everyday items such as car keys, lids, pens and other small objects. As soon as the thumb is in opposition, you can close the entire hand in the tripod grip so the thumb, index and middle fingers meet. The ring and little fingers close.
Precision open grip
With the precision open grip, you can pick up and manipulate small objects with the thumb in opposition. The index finger meets the static thumb in this case. When you apply a close signal, the thumb moves to the midpoint of its range and pauses there. The index finger is then active and under your control while the middle, ring and little fingers remain extended.
Open palm grip
The open palm grip is suitable for carrying trays or plates. You can fully open the hand to provide a flat palm when the thumb is in the lateral position.
Finger point
Finger point allows you to operate keyboards and touchscreens, and to press a bell or button. The hand can be moved to the finger point position when the thumb is in the lateral position. The middle, ring and little fingers close against the palm, and the thumb moves against the middle finger.
Mouse grip
The mouse grip lets you operate a computer mouse. The thumb and little finger close to hold the sides of the mouse, with the middle and ring fingers providing additional stability. The index finger moves to the mouse button to click it and is then retracted. If you want to click, give the hand a signal to close. Use the open signal to let go of the mouse.
Column grip
You can use this grip to push objects or operate larger buttons and switches. We also recommend this grip for dressing since the thumb will not get caught in clothing. With the column grip, the thumb is moved from the lateral position towards the palm. The fingers then close over the thumb, making a sort of fist.
Key grip
This grip is ideal for reading a magazine, using a spoon and for holding flat objects such as plates, credit cards or keys. The fingers close part way when the thumb is in the lateral position. The thumb then closes and touches the side of the index finger. You can then raise and lower the thumb position without moving the other four fingers. This allows you to easily reposition, hold or release the object being gripped.
Relaxed hand position
In the relaxed hand position, the thumb is positioned slightly towards the palm in the lateral position. The other fingers are slightly bent. By applying a further signal, the hand is moved into the hook grip for carrying objects.
