INFORMATION
Risk of injury as a result of excessive strain.
Excessive impact loading typical with competitive sports beyond running or jumping activities,
may weaken the spring elements.
To avoid the risk of accident and possible injury to the patient, the foot must no longer be used
after a noticeable loss of function has occurred.
This noticeable function loss may be the result of reduced spring effect or forefoot resistance,
in some cases accompanied with abnormal noises.
Measure: Have the prosthetic foot examined and, if necessary, replaced at a specialist workshop.
The Functional Ring is to be protected against mechanical damage. The Functional Ring must
be replaced by qualified personnel if it shows any signs of damage (see Sections 4.3 and 4.6).

2.6.2 Carbon Fiber Foot with integrated Shock Absorber and Torsion unit
The main features of the 1C61 Triton Vertical Shock carbon fiber foot are the lightweight construc-
tion and the integrated shock absorber with rotation functionality. This system permits amputees
with MG 3 or 4 the ability to walk effortlessly in everyday life situations including participation in
high energy activities.
The integrated Shock Absorber and Torsion unit helps to reduce vertical and torsional forces in
the extremities during walking. The result is an improvement for both the function and loading
situation of the prosthesis wearer.
The 1C61 Triton Vertical Shock is designed to be used with the footshell and the detachable Foam
Connection Cap. The Foam Connection Cap provides effective connection between the foot and
cosmetic skin foam cover.
The combination of the carbon fiber foot together with the integrated Shock absorber and Torsion
unit offers the following functional advantages:
• Secure heel strike with noticeable plantar flexion
• Progressive movement of the ankle in the mid-stance phase for the natural rollover of the foot
• Dynamic transition from the stance to swing phase
• Smooth dynamic forefoot response and energy return
• Compensation for uneven terrain
• Axial shock absorption
• Compensation of torsion moments
