Zeus
1
Zeus is a multi-articulating myoelectric hand combining ease of control with an
elegant, robust design. The ngers and thumb provide a rm grasp to perform
everyday tasks with ease. The ngers stall individually, allowing them to conform
to the shape of the object, regardless of shape or size.
Read this document carfully before tting Zeus.

Intended Use
2
Zeus is an external prosthetic hand intended to be used alone or with other
appropriate upper limb components to form a complete arm prosthesis, to
be tted only by qualied and certied clinicians. It should be used only by
upper limb amputees and by people with congenital absence of an upper limb.
Zeus is suitable for 3 amputation levels: below-elbow, above-elbow and shoulder
disarticulation, but the nal decision whether Zeus should be used belongs to
qualied medical personnel. Its functionality covers most hand movements.
Zeus including the socket (made by CPO) is designed for only one person during
the whole lifetime of the prosthesis.
Fitting of the product to the patient’s upper limb may be exclusively done by a
qualied and certied CPO.
Zeus is designed for mild to moderate activities.
Indications
Amputation level below-elbow, above-elbow and shoulder disartiqulation
For unilateral or bilateral amputation
Congenital limb deciency of the forearm or upper arm
The patient must be able to understand usage and safety messages and put
them into practice

You can choose from 12 grip modes. The hand has two selectable thumb positions:
opposed and non-opposed.
Opposed thumb in opposition to the ngers on the hand allows choosing grips
like Tripod and Power.
Non-Opposed thumb parallel with the ngers of the hand allows grips like Key
and Finger Point
The speed and force applied by the fingers can be modulated on the basis of
EMG signal

Power Grip
Trigger Grip
This grip is useful for operating
appliances which require trigger
mechanisms like sprays. The hand
grasps the object and conforms
to the shape of the object. The
index nger and middle nger
are controlled proportionatally to
operate the trigger mechanism.
The speed and force applied by
the index nger can be modulated
on the basis of EMG signal.
In this grip, the thumb is opposed,
while all of the ngers can be closed
until they meet the object or no
further close signal is given. The stong
grip provides 152N of force spread
over all four ngers and thumb. This
multi-purpose grip allows you to open
a door or shake hands.
Individual nger stalling means the
grip conforms to the shape of the
object so that you can lift things such
as a wine glass. Thanks to advanced
sensors, the hand optimizes the force
spplied to the object.

also be used to provide
support when getting up
from a seated position.
Open Palm

extent where it provides
a slight curvature to
support plates, bowls

Changing Grips
There are 2 dierent modes to change grip.
Sequential mode
In the sequential mode you can cycle between the grips in the loop. Using the
Change Signal (CS) you go forward in the loop; using the Secondary Change Signal
(SCS), you go back. The grips are split into two groups: with the thumb opposed
and non-opposed. To switch between the groups, you need to manually adjust the
thumb position and a Change Signal or a Secondary Change Signal.
Pairing mode
In the pairing mode, the grips are arranged in a hierarchical manner, allowing for
quick access. The rst level of division is based on the position of the thumb. When
the thumb is in the opposed position, the opposed group of grips is active and when
the thumb is in the non-opposed position, the non-opposed group of grips is active.
To switch between the opposed group of grips and the non-opposed group
of grips, the user has to move the thumb in the desired position and then
provide a Change Signal.
Within each group of grip, there are two subgroups - the primary group and
the secondary group. Each subgroup has two grips within it, the default
grip and the alternate grip.
To switch between the default grip and the alternate grip, provide a Change
Signal.
To switch between the subgroups, primary group and the secondary group,
provide a Secondary Change Signal.
When you change the position of the thumb, provide a Change Signal
to allow the prosthesis to change between the opposed and non-opposed
group of grips.
