Instructions On The Handling Of The Prosthesis; Description And Function; Design - Ottobock 7E10 Helix3D Gebrauchsanweisung

NOTICE
Risk of damage caused by overheating of the hydraulic unit. Extended, continuous use (e.g. lengthy downhill
walks) can lead to overheating of the hydraulic element/ hydraulic damper involving liquid leakage. If activities
are continued, the Helix
The joint must then be sent to an authorised Ottobock Service for inspection.

1.6.3 Instructions on the handling of the prosthesis

NOTICE
Damage caused by corrosion. Prosthetic components must not be exposed to corrosive elements such as
fresh water, salt water and acids.
Using this medical product in such environmental conditions will render all claims against Otto Bock HealthCare null
and void.
NOTICE
Damage due to incorrect environmental conditions. Prosthetic components must not be subjected to intense
smoke, dust, vibrations, shocks or high temperatures. Do not allow solid particles or liquids (such as sweat)
to get into the components. Failure to follow these instructions can lead to malfunctioning and damage to the
prosthesis.
• Avoid areas with extremely high humidity and temperatures.
• Should the joint come into contact with liquid, remove the cosmetic foam cover and let the components dry.
• Should the joint come into contact with salt water, immediately clean it with a cloth moistened with freshwater
and let it dry. Contact your prosthetist to have the hip joint sent to an authorised Ottobock Service Centre for
inspection.
NOTICE
Damage caused by improper cleaning agents. Do not use any aggressive cleaning agents since they could
cause damage to bearings, seals and plastic parts.

Description and function

2.1 Design

The patented Helix Hip Joint is the first commercially available hip joint with hydraulic stance phase and swing
3D
phase control. Its design features enable the prosthesis wearer to achieve a harmonious and smooth gait pattern.
The following particularities characterise the hip joint:
• Spatial movement of the hip: The patented, multi­axis joint structure effectuates spatial movement of the hip.
In addition to usual flexion and extension, this spatial movement is a combination of abduction and adduction
as well as inward and outward rotation imitating the natural movement. Therefore, the Helix
7E10=L for left­side amputees and 7E10=R for right­side amputees are available. In addition, the multi­axis
joint structure results in greater reduction of the leg length during the swing phase and thus facilitates walking
with the prosthesis.
• Hydraulically controlled extension and flexion: An innovative hydraulic unit controls the resistance of the hip
joint during each phase of gait. During the stance phase, it allows for dampened, controlled heel strike with
significantly reduced backward tilt of the pelvis (hypolordosis) as well as harmonious hip joint extension. The
hydraulic unit also controls the stride length during the swing phase. It can be adjusted to the individual require­
ments of the prosthesis wearer.
Helix
can become damaged in extreme cases.
