Michelangelo hand

The AxonBus prosthesis system with the Michelangelo Hand restores numerous functions of the natural hand with various gripping options. Thanks to its highly natural design, it integrates harmoniously into the natural body image.

Soft fingertips

The fingers are made of soft as well as harder materials and thus modelled on nature down to the detail.

Flat oval wrist

The flat oval wrist has a very natural appearance. You can bend and stretch the wrist and also passively rotate it inwards and outwards. Flexion and extension are b.ased on the relaxed wrist (flexible mode).

Main drive

The powerful main drive supplies the gripping movements and gripping force. Actively controlled elements are the thumb, index finger and middle finger. The ring finger and little finger passively follow the movements.

Separately movable thumb

A separate active thumb drive allows you to move the thumb independently. This expands your gripping options – moving the thumb outwards creates a flat, open hand.

Relaxed wrist joint

The AxonWrist mechanical wrist can be flexed and extended as well as rotated inwards and outwards. In a flexible mode, the AxonWrist simulates the movement characteristics of a relaxed, natural wrist. Unnatural compensating movements are thereby avoided, promoting a healthy body posture.

Michelangelo hand design
Natural design

For the product designers and developers, making the appearance and feel of the Michelangelo hand resemble a natural hand as closely as possible posed a special challenge. The fingers are made of both hard and soft materials, and thus based on the natural hand in detail. More so than previously available round wrist joints, the flat oval hand adapter adds to the natural appearance. Compatible prosthetic gloves are available in six hues.

Compatible gloves

Suitable for everyday use, the prosthetic gloves have a multilayer structure and come in six shades. Coloured fibres on the inside simulate the natural vein structure of the human hand. Lamella integrated into the hand shells lend a natural appearance to the movement of the wrist and thumb. A translucent and a black prosthetic glove are available for those who want to show off their modern prosthesis.

Functionality

Variability and gripping force

Seven different grips

Very few parts of the human body are as complex as our hands. Only the perfect interplay between nerves, sinews, a total of 27 bones, 39 muscles and 36 joints makes it possible for us to carry out everyday activities as a matter of course. One of the greatest challenges faced by medical technology is using prostheses to model as many of these numerous functions as possible. With its seven different gripping possibilities, the Michelangelo hand restores numerous functions of the natural hand. Its gripping force is between 6 and 7 kg. You can adjust and control the force needed to hold a heavy or light object with the Michelangelo hand.

Lateral pinch

With a lateral pinch, also known as a key grip, the thumb moves laterally to the index finger. This allows you to laterally grip flat objects such as paper or credit cards.

Lateral power grip

The thumb moves laterally to the index finger. This allows you to also grip medium-sized objects such as a mobile phone.

Finger abduction/adduction

By spreading and closing the fingers, you can hold flat and thin (< 3 mm) objects such as bank notes.

Tripod pinch

With the so-called pinch grip, the thumb, middle finger and index finger form a three-point support to securely hold small objects such as a pen.

 

Opposition power grip

The large opening width of the hand allows you to securely hold objects with a larger diameter.

Open palm

With an open palm, a flat hand position is achieved which allows you to carry, for example, a plate or documents quite naturally.

Natural mode

The Michelangelo hand looks very natural in the resting position. In flexible mode, the wrist yields slightly when counter-pressure is applied.
When you relax the muscles, the Michelangelo hand also assumes a natural, relaxed hand position.

The right prosthesis training helps with its practical use

A good fitting doesn't end once a prosthesis has been professionally adjusted. The better you know your new Michelangelo hand, the more efficiently you can use it in everyday life. This is why Ottobock has developed accompanying practical exercises to familiarise you with the prosthetic hand – so you can reap the full benefits of the numerous functions and gripping options of the Michelangelo hand. Ideally, a specially trained therapist will support you as you work through the multi-level training concept. The contents include information on the daily handling of the prosthesis such as charging the battery, care instructions, storage or switching the prosthesis on and off. This is followed by exercises for learning the different grip options. In addition to the training with your therapist, there is also a DVD which allows you to repeat and familiarise yourself with the exercises at home.

FAQS

Answers for you

How do I get a Michelangelo hand?

There are specialised and certified medical supply companies across Germany that fit users with the Michelangelo hand. Your O&P professional will advise you and answer all your questions regarding a possible fitting with the Michelangelo hand.

I have an upper arm amputation. Can I be fitted with the Michelangelo hand?

For amputations above the elbow joint, Ottobock has developed the AxonArm Ergo elbow components which also work with the Michelangelo hand. Your O&P professional will advise you in detail and answer all your questions about a possible fitting.

How do I control the Michelangelo hand?

The Michelangelo hand is known as a myoelectrically controlled prosthesis, which means you control it with your own muscle signals. Here's how it works: “myoelectric” is the technical term for the current created by muscle activity, which can be measured on the surface of the skin. An electrode on the surface of the skin of your residual limb transmits the muscle signals you produce to the Michelangelo hand in the form of electric voltage. Electric motors and microprocessors then convert these signals into specific movements.

What movements are possible with the Michelangelo hand?

The Michelangelo hand features seven different possible grips. This allows you to grip and hold objects in a targeted manner and to lift heavy as well as light items.

Is it difficult to learn how to use the Michelangelo hand?

 

The technology is highly intuitive, and users can easily learn how to use the Michelangelo hand. However, regular training is important, especially at first. A specially developed training concept, which should ideally be carried out with a therapist, provides the necessary assistance.

Can I shower with the Michelangelo hand?

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

There are no standard prosthesis components for showering and swimming; individual adaptations are made by your O&P professional.

Can I use a touchscreen with the hand prosthesis?

No, this is not possible at the moment, but research and development are underway.

Can I wash my hands with a Michelangelo hand?

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