Prosthetic components
Prosthetic components are the standard parts a prosthetist assembles into an artificial limb, such as adapters, pylons, socket connectors and liners. They are bought by prosthetic and orthotic workshops, rehabilitation centres and humanitarian limb-fitting programmes.
Common types
- Pyramid adapter: the standard male and female connection that allows alignment between parts.
- Tube adapter and pylon: the tube that forms the shank and links the knee or socket to the foot.
- Socket adapter and lamination anchor: connects the hand-made socket to the rest of the limb.
- Rotation and shock-absorbing adapter: allows twisting or cushions impact.
- Liners and suspension: silicone or gel liners, locks and valves that hold the socket on.
What to tell us when you ask for a quotation
- Component type and the connection system it must match
- Material (titanium, stainless steel or aluminium) and component weight
- Maximum user weight and activity level rating
- Tube diameter and length, and adapter offsets
- For liners: size, thickness, profile and lock or seal-in type
- Quantity, destination country and the delivery terms you want (for example EXW, FOB or CIF).
Documents to ask for
Buyers usually ask for CE marking under the EU MDR or local registration, ISO 13485 for the maker, and ISO 10328 structural test reports for lower limb components.
Certificates and registrations belong to the product and its manufacturer. We check them with you against the rules of your market before any order.
Are components from different makers interchangeable?
Many lower limb components use the common pyramid connection, so parts from different makers can often be combined. The prosthetist should still check that each part is rated for the user's weight and activity level.
Send us the specification and quantity. We compare manufacturers in China and reply with options, lead times and the documents that come with each product. NJMC sources and checks; it does not manufacture.
