Microprocessor Elbows
The Ottobock DynamicArm Elbow is a myoelectric prosthesis, which incorporates a powerful electric motor to help both flex and extend the elbow while holding up to 11 lbs. In addition to hand and rotation of the wrist joint, elbow joint flexion can also be controlled by muscle signals. The prosthesis is particularly inconspicuous, thanks to operating noise optimized by sound engineering as well as the slightly dampened – and completely silent – free swing phase. These special technology features are integrated in an elbow joint-forearm system with a natural, anatomic design. The shape and basic color blends in with the overall image of the human body.
The Espire Pro from College Park is a revolutionary powered elbow that is easy to use and anatomically correct. With a removable 3000 mAh battery and a comfortable center of mass, this elbow functions all day with ease. The electrical lock, free swing options, and accessible power button add ease to patients’ everyday tasks. The Pro is compatible with most terminal devices, switches, touch pads, and electrodes on the market. Prosthetists have access to settings for control strategy and device setup via the Espire Hub iPad app.
12K50 ErgoArm Electronic Plus is a lightweight and versatile electronic locking elbow that is compatible with a myoelectric hand or terminal device. The internal Infinite Position lock is cable-operated and can be locked, or unlocked, under load in any position. It can bear a load of up to 230Newtons (51.71lbs) at a forearm length of 305mm (12 in). The Slip-Stop function makes it possible to lower the forearm in a controlled manner without having to fully release and reactivate the lock. In the ErgoArm Electronic plus, this feature is electronic versus mechanical. Automatic Forearm Balance (AFB) supports flexion by using energy stored during extension. It promotes a smoother motion when swinging the arm, making it easier to lift the arm. For improved cosmesis, the AFB finger wheel is now the same color as the forearm shell. Easy Plug allows the electrode and battery connecting cables to be plugged into the elbow cover. Internal cables enhance overall cosmetic appearance while also increasing durability. Electronic Lock enables the user to control the elbow’s locking and unlocking with myoelectric signals or by means of a switch. Eight switching modes are available for customization of the lock control system to the user’s personal requirements. A new membrane cover in the crook of the arm protects internal components and prevents user’s clothing from potentially getting trapped, enhancing overall appearance and functionality.
The Fillauer Motion E2 Elbow is a small, lightweight electric elbow for use with smaller individuals or adolescents. A very versatile elbow, it can be used with switch control for simplicity, or with a ProControl 2 for myoelectric proportional control. Available in tan, light brown, brown and jet black colors.
The Utah Arm 3+ provides sensitive and precise electronic control of the elbow and optional Hand or ETD (Electric Terminal Device) simultaneously. Automatic sensitivity adjustment can be performed using Auto-Cal. Options include MC Wrist Rotator, Flexion Wrist, and Multi-Flex Wrist. The U3+ includes a Dual Lock System (friction lock and a locking pin for heavier loads). Silent Freeswing is provided, disengaging the motor and saving battery life as well as providing a more natural movement of the arm when relaxed. Wireless Bluetooth communication is available for computer interface. The U3+ is compatible with almost all other manufacturers’ terminal devices. Available in tan, brown, or black.
