SYMBIONIC® LEG 3

SYMBIONIC® LEG 3


HC005139

Featuring the latest advances in Bionic Technology by Össur, SYMBIONIC LEG 3 is the next generation of integrated prosthesis that combines a microprocessor knee and powered microprocessor ankle with proactive ankle flexion. SYMBIONIC LEG 3 was designed to enable users to experience greater safety, symmetry and confidence when walking, without needing to adapt their walking style or otherwise compensate for their prosthesis.

Key features

  • Designed to enhance user’s safety through powered toe lift and stumble recovery, which can help reduce the risk of trips and falls.
  • Enabling consistent ground clearance allows the prosthetist to better match the user’s native limb length. Combined with easier swing initiation, SYMBIONIC LEG 3 encourages greater symmetry while walking and helps restore a more natural gait.
  • With its unique intelligent terrain adaptation capabilities, the SYMBIONIC LEG also can help enhance users’ confidence, by providing stability while walking on such everyday surfaces as grass, slopes, or uneven ground. This enables the user to walk more easily without having to literally watch their every step.
  • Extension lock mechanism, to lock the knee in full extension and increase safety and comfort under specific circumstances.

SYMBIONIC LEG 3 now features a more powerful knee actuator and new kinematic sensor for better stability, increased support across a wider range of stance flexion, and faster, more consistent swing extension.

Impact Levels

Impact LevelExample

Low

Daily activities involving gentle, steady walking with the use of a walking aid.

Example: Moving around at home, modest walking in the community.

Moderate

Daily activities involving average walking with the ability to vary speed or walking pattern.

Example: Going to the shops, confident outdoor walking.

SYMBIONIC® LEG 3 Features

Full Length Toe Lever

Full Length Toe Lever

The full length keel/toe lever matches the length of the sound foot, providing improved support to the prosthetic limb during late stance. It ensures that users spend equal time on the prosthetic foot and natural limb, thus providing improved walking dynamics and reduced impact to the sound limb.

Benefit: Improved walking symmetry and reduced impact to the sound limb.

Heel Height Adjustability

Heel Height Adjustability

Heel height can be adjusted for various types of shoes to ensure correct alignment. Users can easily change shoes to fit most occasions as the heel height can be adjusted within the given range.

Benefits: Adjustable heel height minimizes misalignment of the prosthesis thus reducing walking fatigue and discomfort experienced with poor alignment.

Proportional Response

Proportional Response

The layering of carbon fiber, optimized through extensive computer analysis and mechanical testing, ensures that the deflection of the carbon fiber heel and forefoot components are proportional to the user’s weight and impact level.

Benefit: Customized construction optimizes walking efficiency thus reducing fatigue for the user.

Split Toe

Split Toe

A split toe feature allows the foot to adjust to uneven surfaces, allowing amputees to walk with stability and comfort on uneven ground.

Benefit: Helps to maintain balance, stability and reduces peak impact during loading.
