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 or black carbon.

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

Your prosthetist sets the parameters of the bebionic hand individually in the adjustment software to fit your personal 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 finger, 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 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 prosthetist 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 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.

FAQ

  • Who can wear a bebionic hand?

    The bebionic hand is suitable for all users who have intact muscle activity in one or more muscles in the residual limb.

    The bebionic hand is especially suitable for users with low to moderate activity levels, as heavy activity should be avoided.

  • Where can I test a bebionic hand prosthesis?

    The bebionic hand is fitted by certified prosthetists and a trial fitting may be obtained. It takes place over a period of time and is monitored by Ottobock when needed.

  • How long will it take before I can use the bebionic hand correctly?

    As everyone is different, it is difficult to give an exact time frame. It may take less time for some than for others. However, the amount of training required to confidently use a myoelectric hand prosthesis can be compared with learning to play a musical instrument.

    After a few hours, it is usually possible to open and close the prosthetic hand. After this, the hand prosthesis also needs to be used on a regular basis if it is to be integrated successfully at work and in your everyday routine. It usually takes around three to six months before most users have integrated the prosthesis into their daily lives.

  • What is involved in a fitting with a bebionic prosthetic hand?

    A fitting includes all the components integrated into a socket, a customised socket and the correct settings for the hand, which will be adjusted by the prosthetist. The assembly and training with the prosthesis are of course part of this, as well as regular service inspections.

  • How long does the battery in the bebionic prosthetic hand last?

    The operating time of the battery in the prosthesis depends largely on how the prosthesis is used in day-to-day life. On average, the battery will last a whole day. We recommend charging the battery every day. This ensures that the prosthesis is always ready to use.

  • Can the bebionic hand be used without the glove?

    Wearing the bebionic hand with the prosthetic glove is recommended for daily use. It protects the hand against moisture, dirt and dust.

  • How do I control the bebionic hand?

    The bebionic hand is what is known as a myoelectrically controlled hand prosthesis, which means you control it with your own muscle signals in the residual limb.

    Here's how it works: "Myoelectric" is the technical term for muscle activity in the residual limb that generates electric current in the microvolt range. This is registered by electrodes and calculated in fractions of a second. Based on this data, electric motors in the prosthesis control the gripping and turning movements of the prosthetic hand.

  • I have an upper arm amputation. Would a fitting with the bebionic hand be a possibility for me as well?

    Ottobock has developed the ErgoArm and DynamicArm elbow components for amputations above the elbow joint. Your prosthetist will advise you in detail and answer all your questions regarding a possible fitting.

  • What movements are possible with the bebionic hand?

    The bebionic hand offers 14 different gripping options. The user and prosthetist can select a total of eight of these options. You can see the different grips under the "Grips" tab.

  • Can I shower or wash my hands with a bebionic hand?

    No, you cannot shower or bathe with the bebionic hand.

    There is no standard prosthesis components for showering and swimming; individual adaptations are made by your prosthetist.

    However, you can wash your hands provided that the prosthesis glove is intact and the cuff is long enough that no water can get into the prosthesis from the end.

  • Can I use a touchscreen with the hand prosthesis?

    A touchscreen can be used with the bebionic hand small if no glove is worn.
