3 Function
The EchelonVT comprises a hydraulic body assembly containing adjustable hydraulic valves.
The valves can be independently adjusted to increase and reduce hydraulic resistance to
plantarflexion and dorsiflexion. The proximal part of the hydraulic body assembly contains a
spring component that allows the pyramid tube to deflect and/or rotate through a limited range
under an axial and/or torsional load. When the load is removed the spring returns to its original
position. The effect of this movement is to attenuate any shock forces that would otherwise
be transmitted to the residuum/socket interface both in axial and rotational directions. The
hydraulic body assembly is connected to a carrier assembly via two pivot pins. Heel and toe
springs are attached to the carrier assy using screws. The foot is wrapped in a UHM PE sock which
is in turn surrounded by a PU foot shell.
4 Maintenance
Maintenance must be carried out by competent personnel.
It is recommended that the following maintenance is carried out annually:
• Check for visual defects that may affect proper function
• Clean and relubricate bearing surface. Use Sapphire Endure ( 928015) or equivalent PTFE
loaded grease
(see Section 8 Maintenance Instructions).
• Remove the foot shell and glide sock, check for damage or wear and replace if necessary.
• Check all screws for tightness, clean and reassemble as necessary.
• Visually check the heel and toe springs for signs of delamination or wear and replace if
necessary. Some surface damage may occur after a period of use, this does not affect the
function or strength of the foot.
The User should be advised to contact their Practitioner if their condition changes.
Any changes in performance of this device must be reported to the Practitioner. Changes in
performance may include:
• Increase in ankle stiffness
• Changes in axial or torsional stiffness
• Reduced ankle support (free movement)
• Softening of springs
• Excessive play in bearings
• Any unusual noise
Cleaning:
Use a damp cloth and mild soap to clean outside surfaces, do not use aggressive cleansers.
