- Rudenko elbow module with a passive flexion. It is used
in Rudenko arm prostheses. 2 dimension-types. The passive flexion
is up to 120° in the elbow joint. There is a stepless fixing and
unfixing device of the elbow joint. Fixing and unfixing are provided
by the lever displacement by of healthy limb or by pushing of
the underarm key. There is an arm passive rotation unit (rotation
range of ±45°). The rotation moments are adjusted.
- Elbow module with an active flexion. It is used in Rudenko
mechanical pulling arm prostheses with a single cable hand module
with a spring grip both with a passive rotation unit and without
it. There is an automatic fixing in the elbow grip. Unfixing and
active flexion is performed when the control cable pulling. There
is a passive rotation of the forearm around the arm. Maximum flexion
angle of elbow joint - 120°.
- Active elbow module. It is used in mechanical pulling
arm prostheses with a single cable hand module with a spring grip
and with a passive rotation unit. The active flexion is provided
by the pulling of the control cable with automatic fixing in every
intermediate position. The unfixing is happened when the initial
control cable pulling. When pulling of the control cable weakens
the flexion mechanism is automatically fixed. The maximum flexion
angle of elbow joint - 110°.
- Child's elbow module with a passive flexion. It is used
in arm prostheses with a single cable hand module with a spring
grip. The elbow joint fixing mechanism has a key on the internal
side of the elbow. The turn-on of the fixing and unfixing mechanism
happens by the key pushing against an amputee's body. There is
a passive rotation unit.
