C-Leg 4 Knee Joint Ottobock
Desain
In order to withstand the varied demands of everyday life, the frame is made of carbon – an especially strong, high-grade and lightweight material. The frame houses and protects the electronics, the hydraulic unit and the battery. Thanks to its new design, the C-Leg has a lower system height and therefore a larger fitting spectrum.
Hidrolik
The hydraulic unit controls the C-Leg. It generates movement resistance for flexion and extension during the stance and swing phase.
Bluetooth
Integrated Bluetooth® technology permits straightforward communication with the joint. An existing connection is displayed with an LED. Bluetooth® can be deactivated if necessary.
Lithium-ion battery
A lithium-ion battery provides energy for controlling the knee joint. It is located right in the rotation axis of the C-Leg. If you use the C-Leg on a daily basis, we recommend that you always charge the battery overnight.
Knee angle sensor
The knee angle sensor provides important data: It measures the flexion angle and angular velocity of the joint.
Electronic Control Unit
The integrated microprocessor receives and processes sensor signals. It controls the movement of the knee joint in real time.
Inertial motion unit (IMU)
The gyroscope and acceleration sensors allow the position and acceleration of the C-Leg in space to be measured.
Weatherproof
The C-Leg 4 has an IP 67 rating, which protects it from damage due to incidental contact with or temporary submersion in fresh water. Because the C-Leg 4 is considered weatherproof, you don’t have to worry about getting caught in the rain or being around water.
Intuitive Stance
Available only in Ottobock microprocessor knees, intuitive stance automatically activates to fully block the C-Leg from bending or buckling while you are standing, allowing you to distribute your weight evenly between both legs. This helps alleviate pressure on your sound side and helps you maintain a more stable, comfortable position when standing for a long period of time, even on slopes or uneven terrain.
Backward Walking
The patented inertial motion unit (IMU) on the C-Leg provides stability when taking steps backward or while backing up. Contrast this to other manufacturer’s microprocessor knees, which do not accommodate backward walking, potentially causing their knees to collapse when stepping backward.
Stairs, Slopes, & Ramps
The stance flexion feature in C-Leg provides hydraulic resistance against knee flexion (bending) mimicking the quadriceps muscle. This controlled knee flexion occurs early in the stance phase of your gait cycle while you are bearing weight on the prosthesis. Providing shock absorption, stance flexion allows you to securely walk up and down slopes and ramps, negotiate uneven / challenging terrain, and to descend stairs step-over-step.
Enhanced Stumble Recovery
With sensors that are always actively controlling and adjusting resistance while you are in the swing phase of gait, the C-Leg 4 can detect the pattern of movement that resembles a fall and will respond immediately by providing even greater resistance. This constant presence of swing flexion resistance paired with an immediate increase in resistance allows you to safely put your full weight onto your prosthesis, so you can easily recover from a stumble and prevent a potential fall.
MyModes & Cockpit App
The Cockpit app allows you to adjust the C-Leg to your individual needs in everyday life using an iOS or Android device. With the Cockpit app, you can check your C-Leg’s battery life, determine your daily step count, or select preconfigured MyModes for specific activities like biking or golfing.
Original Microprocessor Knee
The Ottobock C-Leg is the original microprocessor knee. Since its launch in 1997, the C-Leg has set the standard for every other knee available, and is the world’s most studied prosthetic device. Our research proves that with C-Leg, you will experience less falls. Because of the increased safety, your confidence in the knee will give you the freedom to no longer think about how or where you walk. No wonder 94% of amputees who use C-Leg prefer it to their previous prosthesis.² Not all microprocessor knees improve quality of life. Know the difference.
