Modular Knee Joint with Rotary Hydraulic

The 3R60 knee joint was developed to support you with a variety of movement patterns in everyday life. The large knee flexion angle facilitates activities in a kneeling position as well as sitting on the floor, thereby providing greater freedom of movement in various everyday situations.

How does the EBSpro work?The mechanical principle of the EBSpro is based on the proven 3R60 prosthetic joint.The polycentric prosthetic joint has five axes that are arranged to form a ring. The anterior axis chain is designed like a conventional four-axis joint, but the posterior linkage bar is interrupted by an additional pivot point (Fig. 1). The proven design thus allows for two different modes of operation: swing phase mode and stance phase flexion mode. Two specially configured miniature hydraulic units (Fig. 2, A+B) control the two modes. Outstanding performance during the stance phase is the key feature of the 3R60.The spring and hydraulics combination in stance phase flexion mode is individually adjustable and can be precisely adapted to suit the requirements of the prosthesis wearer. Thanks to the progressive nature of the EBS resistance – realised with an auto-adaptive EBS unit – the effect can adapt itself over a large range of walking speeds for the first time.The higher the walking speed, the greater the extent to which flexion is limited. The lower the walking speed, the less damping resistance takes effect. This ensures greater stance phase flexion (Fig. 3). In this way, this important function adapts to various everyday situations. For the prosthesis wearer, this means enhanced safety and comfort as well as a highly natural gait pattern.

With over 100,000 fittings to date, the C-Leg is trusted by more users than any other microprocessor knee in the world. And it’s no wonder: Studies show the C-Leg provides the exceptional reliability and performance users need to focus on what really matters: enjoying a healthy, active lifestyle.The C-Leg combines proven reliability with a waterproof design (IP68), providing confidence across a wide range of everyday environments.

Do you need a reliable partner that helps you easily overcome a variety of challenges, both at work and in everyday life?Dynion lets active users like you do things such as walking down stairs and ramps, walking dynamically in all directions, cycling and swimming in fresh, salt and chlorinated water.
