Hand
modules for Rudenko mechanical pulling forearm and arm
prostheses:
- Rudenko hand module with an active grip. The module has three
control cables (grip, finger opening and finger fixing with manual
locks) and a passive rotation unit
- hand module with a spring grip (pulling forearm prostheses).
The module has three control cables (grip, finger opening, finger
fixing with manual locks). Finger opening cable passes through
the palm part. Other cables - through the rotation unit. There
is a passive rotation unit
- Rudenko hand module with a spring grip and an active control
cable. The module has three control cables (finger opening, clutch
and finger fixing with manual locks).
Hand modules for mechanical pulling forearm and arm prostheses:
- single cable framed hand module with spring grip. High strength
of the spring grip. Capability of the fourth finger fixing in
the maximum flexion position (so called "hook" position). This
position allows carrying loads. There is an opening finger cable.
The fourth finger unfixing from "hook" position happens when the
hand opens on 40 mm. The hand mechanism fulfills finger fixing
in the closed finger position. There is a passive rotation unit.
- single cable framed hand module with an active grip. Capability
of the fourth finger fixing in the maximum flexion position (so
called "hook" position). Griped objects are fixed between the
thumb and the forefinger and the middle finger block with the
following clutching when the cable is pulled. The hand is opened
by the spring when cable is pulled. Repeated pulling of cable
closes the hand. There is a passive rotation unit.
- single cable framed hand module with a spring grip There are
2 variants: with a passive rotation unit and without a passive
rotation unit. The grip is provided by a spring. The finger opening
is provided by the control cable. Finger fixing is performed in
the closed position and when they are open on 80 mm. The fourth
and the little fingers fix in "hook" position when fingers are
in closed position. Unfixing of "hook" happens automatically when
fingers open on 40 mm.
- Framed functional cosmetic hand module with spring gripIt is
capable to fix the fourth finger in the maximum flexion position
(so called "hook" position). The hand module is opened by a healthy
limb.
Child's hand modules:
- child's single cable hand module with a spring grip. The module
is designed for children from 2 to 6 years. It is used in forearm
and arm prostheses. Stepless finger fixing in the grip position
with a passive clutching. There is a passive rotation unit.
- child's hand module is used in mechanical pulling forearm and
arm prostheses and designed for children from 7 to 10 years. The
grip is provided by spring. Finger opening is provided by the
control cable. Finger opening is fixed when the finger opens on
distance of 40 mm. The fourth and the little fingers fix in "hook"
position when fingers are in closed position. Unfixing of "hook"
happens automatically when fingers are opened by control cable.
There is a passive rotation unit (hand rotation around its longitudinal
axis).
