Project Circleg is developing the Circleg lower-limb prosthetic system for above-knee and below-knee amputees. It is made from reinforced and certified recycled plastic, creating lightweight, high-quality and comfortable prosthetic components.
Appropriate & User-centered
Project Circleg has collaborated with Swiss and East African amputees and orthopaedic technicians to develop an appropriate prosthetic system according to ISO standards and recommendations from ISPO and WHO. The user-centeric design approach is key to integrate the needs and requirements of amputees into product development, and thus simplify their everyday life with appropriate prosthetic care.
Modular & Customisable
Project Circleg ensures individual customisation of the Circleg prosthetic system through its modular design. This allows for adaptation to body size, activity level and color preferences of the beneficiary, while simultaneously enabling simplified maintenance and replacement of broken parts.
Swing-control mechanism
A mechanism incorporated in the knee joint swings the leg forward while walking in order to prevent dangerous trip hazards.
Protection cap
The polycentric knee joint is equipped with a protection cap, which allows a kneeling position and protects the joint from dirt.
Ankle joint
The ankle joint allows a squatting position and therefore the use of a squat toilet.
Modular System
The Circleg prosthetic system consists of a polycentric knee, a pylon and a dynamic foot with an ankle joint. Its components can be adjusted individually to the body measurements of users and are connected with the well-known pyramid adapters.
Protective Cap
Enables a kneeling body position and protects the polycentric knee joint from dirt and external impacts.
Polycentric Knee
Provides a high level of stability and includes a swing-control and foot clearance mechanism to prevent dangerous trip hazards. A manual lock secures the prosthesis in a straight position when needed.
Pylon
Provides the Circleg prosthetic system with an appealing shape and is customizable to the leg length of the users.
Ankle Joint
Allows a squatting position and therefore the use of a squat toilet. The ankle joint can be manually released and secured.
Dynamic Foot
Enables a satisfying roll-over and energy return while walking by simultaneously offering great stability in the stance phase. Its modularity allows the individual adjustments to body weights, foot sizes and activity levels of the users.
Be among the first to benefit from the Circleg system
Project Circleg aims to launch the Circleg prosthetic system in 2022 in East Africa. However, you are already now more than welcome to contact us for detailed product information and pre-orders.
Interdisciplinary Development
Project Circleg’s team of designers and engineers is currently refining and testing the prosthetic system in close exchange with acclaimed experts, academia and industrial partners in Switzerland and East Africa. For this, we follow the procedures outlined by the European Medical Device Regulations ensuring quality and safety for the users.
High-performance material
The Circleg prosthetic system is made from reinforced and quality controlled recycled plastics meeting the demanding requirements of a durable lower-limb prosthesis. Development efforts are aimed at fulfilling the highest static and dynamic load requirements, as well as ensuring biocompatibility and recyclability.
Circleg Cycle
Project Circleg is establishing a local material cycle with partners active in plastics recycling and manufacturing – in line with the principles of the circular economy.
Recycling
Post-consumer plastic is collected, sorted, washed, shredded and reinforced with glass fibres to create a certified material that meets the requirements of a lower-limb prosthesis.
Production
The prosthetic parts are manufactured by simple and on-site available production methods, differentiating between standard parts and components adaptable to the individual body measurements of the users.
Distribution
The pre-assembled prosthetic parts are dispatched to local Hospitals, NGO’s, Health Centres and Orthopaedic Workshops.
Fitting & Adjustment
The Circleg parts are individually adapted to the user by an orthopaedic technician.
Use & Repair
The Circleg prosthetic system is now ready for use. Thanks to it’s modularity, individual parts can be easily maintained, repaired and replaced.
Return
Broken parts are collected and returned to the material cycle in order to produce new Circleg components.
