12K50 ErgoArm Elbow with Electric Lock

Our newest addition to the ErgoArm Elbow family, the 12K50, can be controlled electrically or by cable.

Infinite Possibilities

Engage the unique SlipStop function with either a myoelectric signal 12K50 or a slight pull on the cable.
Reposition the arm without fully cycling the lock (only 7mm excursion) and then lock wherever needed.

All elbows lock and unlock completely for an infinite number of positions - even under a 50 lb. load.

Innovative Wiring System

Power and signal wires are already integrated into the elbow with our Easy Plug, protecting the wires from damage while also creating a more natural look and feel.

Adjustable Automatic Forearm Balance (AFB)

AFB compensates for the weight of the forearm and gives it a comfortable and natural-looking swing.

Compact Turntable

Turntable is so compact that the distal end of socket can be brought within 3cm of the elbow axis.

Ideal for long transhumeral and elbow disarticulation amputees.
Easy-access external humeral rotation friction adjustment can be set with a coin.

Versatile

All ErgoArm elbows come in two sizes, 45mm and 50mm, and work in conjunction with Otto Bock 45mm and 50mm wrist units.

With the new 13Z68 adapter it's easy to connect sockets built for other systems to ErgoArms.

The 12K50 allows for the electric control of 6 functions:

Opening and closing the hand
Pronation and supination of wrist unit
Locking and unlocking of elbow unit

Otto Bock's ErgoArms offer unique function with good looks and low height.
