Overview

With the 3R41, the latest in synthetic material technology is conquering lower limb prosthetics.

This locking knee joint offers additional advantages: it is moisture-resistant, lightweight and especially resistant to wear. Transfemoral amputees with very low activity levels and the highest need for safety benefit from the easy handling of the innovative release mechanism in particular it can even be triggered under partial load.

The lower joint section is equipped with a 30 mm diameter tube clamp.

Functions and Benefits:

The innovative locking mechanism automatically secures the joint at full extension and the user can hear and feel the lock latch engage. The joint can be unlocked using the pull cable or by pressing the lock latch (patella). In developing this knee joint, special attention was paid to the balanced relationship between the unlocking force and the load on the prosthesis in order to make handling even safer.

Through the use of plastics, the joint is particularly lightweight, wear-resistant and easy to maintain. It is also resistant against humidity and splashed water, offering the user greater flexibility.

Its modern design has functional advantages as well. The front plastic flap prevents pinching the fingers in the joint gap and also protects the cosmetic foam cover. To adjust the prosthetic alignment or to compensate for a hip flexion contracture, the proximal pyramid adapter can be shifted in the A/P direction.
