PROTEOR HYDEAL II Notice D'utilisation page 9

C. Mechanism of action
When in extension, the system of linkages ensures that the instantaneous centre of rotation is to the rear of the load line, which keeps
the knee stable during the stance phase. The speed of every flexion and extension movement can be adjusted independently.
An adjustment on the extension assist cylinder modifies the force applied to extend the knee.
Comment: a "Short cylinder" kit is available. It reduces the total height of the knee by 22 mm.
3. INTENDED USERS/INDICATIONS
This medical device is supplied to healthcare professionals (prosthetists/orthotists) who then instruct the patient in how to use it. The
prescription is drawn up by a doctor. The doctor works with a prosthetist/orthotist to assess whether the patient is suited to using the
device.
This device should be used on ONE PATIENT ONLY. It must not be reused on other patients.
The maximum knee flexion is 145°. This flexion may, however, be limited by the volume of the socket or by the cosmetic covering.
4. CLINICAL BENEFITS
The device allows:
•
Everyday activities and certain sports (cycling, running, rowing) thanks to the absence of a cusp (or "over-centre" point) in flexion
and a flexion angle of up to 145°.
•
Changes in pace of walking, accommodated by the hydraulic unit.
•
High levels of stability and safety in the stance phase thanks to the 4-axis joint geometry.

6. ASSEMBLY AND FITTING TO THE PATIENT
A. Assembly
When tightening, comply with the following sequence and torques for the screws on the 34 mm diameter tube:
1. Tighten screw V1 to a torque of 5 Nm
2. Tighten screw V2 to a torque of 5 Nm
3. Retighten screw V1 to a torque of 5 Nm
Assembling the short cylinder kit (1P11067):
Using the kit (sold separately):
Suitable when a smaller overall knee size and/or less powerful extension assist is preferred.
Installation:
Remove the cylinder and the spring mounted on the knee and replace them with the elements supplied.
Do not tighten the assembly forcefully until it locks.
Guideline information:
The new assembly at its maximum "screwed-in" setting applies a force equivalent to the original assembly
tightened to 6 turns less than its maximum setting. The knee is then about 30 mm shorter overall.
B. Aligning
Static alignment:
INSTRUCTIONS FOR USE
This device is exclusively intended to be used as prosthetic equipment for patients who have undergone
transfemoral amputation, hip disarticulation or knee disarticulation. It is specifically recommended for active
to very active patients (L3/L4) as it enables them to perform everyday activities as well as certain sports
(cycling, running, rowing).
Maximum weight (including carried load): 125 kg
